A new rover to land on Mars – ScienceBlog.com

The Mars 2020 mission is scheduled to launch at the end of July. Its goal is to land the Perseverance rover on the Red Planet and collect samples in the hope of finding signs of past life.

While Mars remains an inexhaustible source of inspiration for Hollywood films, it equally fascinates NASA, which has made its exploration a priority. Since the early 2000s, the US space agency has successfully carried out eight missionsdesigned to study its geological and climate history. The next step in this programme is the upcoming launch from Cape Canaveral of a massive Atlas V rocket carrying the Perseverance rover on a new mission dubbed Mars 2020, which will land on the Red Planet on 18 February 2021.

Packed with cameras and high-tech scientific instruments, the rover, approximately the size of a car, aims to answer the question that has been nagging the astrophysics community ever since the early days of Martian exploration: could Mars have once been home to life? After focusing on the presence of water on the planet and on its habitability, Mars 2020 marks the third and latest step in a series of missions, and will be primarily dedicated to the search for signs of fossil life, says Sylvestre Maurice, an astronomer at the IRAPin Toulouse (southwestern France). With the support of around 200 scientists, engineers and technicians from several CNRS and French university laboratories,the scientist helped develop the SuperCam laser camera, one of seven scientific instruments carried by the Perseverance rover. Based on many of the features of the Curiosity rovers ChemCam deployed on Mars in 2012, SuperCam was enhanced with new functionalities such as Raman and infrared spectrometers. These techniques, the first of their kind to be used on the Red Planet, can identify bonds between atoms and the way in which molecules are organised. As a result, they are able to detect complex structures favourable to the preservation of biosignatures in SuperCams targets, he explains.

To maximise their chances in the search for Martian biosignatures, the Mars 2020 team chose the Jezero crater as their landing site. Approximately 3.5 billion years ago, this area, 45 kilometres in diameter, was home to a vast lake to which several rivers converged, forming deltas whose remains are still visible today. The very early presence of water, together with extensive sedimentary deposits, makes Jezero a particularly promising environment for the detection of traces of life. The site also includes a wide range of geological features, which will help Mars 2020 achieve its other primary goal, namely the collection of some thirty soil core and rock samples reflecting the geological diversity of the planet. Once the samples have been enclosed in metal tubes kept inside the rover, they will be sealed and stored on the Martian surface, and eventually brought back to Earth during a future sample return mission scheduled by 2030, Maurice explains.

This unprecedented sampling operation will be carried out using the SuperCam instrument. Its high-resolution colour camera attached atop Perseverances mast will make it possible to accurately determine the geological and environmental context associated with each sample of rock or regolith thanks to the analysis performed by the instruments three spectrometers.In addition, SuperCam will be the very first scientific instrument sent to Mars to be equipped with a microphone. By listening to the impact on the rocks each time the laser is fired, this system will provide information about the hardness of the geological samples targeted, Maurice says. The device will also be used to pick up the sound of the Martian wind and detect possible signs of wear and tear to the equipment by continuously recording the noises made by the rover.

Filled with cutting-edge technology, the SuperCam laser camera took five long years to develop by several French research laboratories. Although from the outside the instrument looks like Curiositys ChemCam, which our team had previously helped to design, it contains three additional analysis technologies packed into exactly the same volume. This required the miniaturisation of numerous components, explains Pernelle Bernardi, a systems engineer at the LESIA,in charge of the specifications and performance of the SuperCam. This was a major challenge that the French team met with flying colours. However, just as the production of the flight model to be mounted on the rover neared completion, things went badly wrong when the optical component of the instrument was being tested inside a heat chamber in November 2018. The temperature rose to nearly 250 C, well above the acceptable limits, quite literally roasting the instrument.

Following a crisis meeting with US mission officials and representatives from the French space agency, CNES,the decision was taken to rebuild the entire laser camera, using all the available spare parts. The French team worked flat out, day and night, and rebuilt the instrument in six months, even managing to enhance its performance. The primary mirror of the first SuperCams telescope had a tendency to deform when cold, which resulted in a significant widening of the focus point of the infrared laser beam, Bernardi explains. The November 2018 incident therefore gave us the opportunity to replace this defective mirror and thereby significantly improve the laser shot.

Completed in June 2019, the upgraded version of the SuperCam was then shipped to NASAs Jet Propulsion Laboratory in California in order to be attached to the top of the rover mast. We visited the site several times last year to ensure that the instruments laser beams were still perfectly aligned during tests carried out in an environment very close to that of Mars, and it was indeed the case, says Bernardi, who was awarded the CNRS 2020 Crystal Medal for her key role in the construction of the device. A few weeks before the Covid-19 crisis broke out, the fully-assembled rover had reached the Kennedy Space Center at Cape Canaveral and was docked to the descent vehicle. It was then placed in the capsule that will enter the Martian atmosphere, this structure being itself attached to the cruise stage, which will fly the entire system to its final destination. Sheltering behind its heat shield, Perseverance is now waiting for the green light from NASA to begin its long journey to Mars.

Exploring the Fundamental Mysteries of the Universe by Seeing the Invisible – SciTechDaily

Michael Troxel has always liked puzzles, especially challenging ones. Which is fortunate, since his job is solving some of the most perplexing, fundamental mysteries of the universe.

At some point in middle school I asked myself, Whats the hardest thing that I could try to do? he said. And at that point the hardest thing I knew about was astrophysics, so I think that was probably the first motivation for choosing this career, if Im honest. But that was before I understood what it actually meant.

A cosmologist and assistant professor in the Department of Physics, Troxel has spent the past two years as the cosmology analysis coordinator in the Dark Energy Surveyan international collaboration involving 500 scientists analyzing a massive dataset of about 400 million celestial objects. It has been what I think is one of the most complex and difficult analyses ever performed in cosmology, which has only been possible with the contributions and leadership of dozens of my colleagues, Troxel said. The outcome will span about 30 published research papers with more than 200 contributing scientists.

Today, in recognition of his contributions to the field, Troxel was granted an award through the Department of Energy Early Career Research Program. Founded to bolster the nations scientific workforce by providing support to exceptional researchers during crucial early career years, when many scientists do their most formative work, the program will support 76 scientists in 2020. It is a welcome validation that my time supporting this project has been well spent, Troxel said. It will also give my research group the resources to tackle some of the hardest problems we face in cosmology.

The award offers five years of funding for a specific project, which Troxel will partly use to support his work on a successor to the Dark Energy Survey: research using the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST), which is scheduled to begin operations in 2023, within the Dark Energy Science Collaboration (DESC). Located in Cerro Pachon, Chile, the facility is one of the three large, state-of-the-art telescopes that will come online in the coming decade, including the Nancy Grace Roman Space Telescope that Troxels group also works with. Rubin and Roman will do many of the same things that the Dark Energy Survey does, but 10 times better, Troxel said.

All focus, in part, on the two most pressing cosmological mysteries left to solve: dark matter and dark energy. Theyre the pieces of the universe that we just dont understand, Troxel said. And a bit frighteningly, they seem to make up 95 percent of the universe.

The first, dark matter, is difficult to research because scientists have yet to see itit doesnt interact with light in the way ordinary matter does. But it does interact with gravity, and current astrophysical modelswhich have been very successful at predicting how the universe has evolvedimply that there is five times as much matter as we can see in the form of this dark matter.

Troxel specializes in gravitational lensing, or how gravity bends the path of light and distorts images of distant galaxies. By taking large-scale images of the universe from observatories like Rubin and Roman and analyzing those distortions, he can map where dark matter is located. Through the Dark Energy Survey, Troxel and others have made such maps for about an eighth of the sky. Rubin will allow them to map the entire southern hemisphere.

The other mystery, dark energy, involves the expansion of the universe. Since the Big Bang, all of the universes cosmological objects have been moving away from each other. Until the last few decades, scientists largely expected that the objects would slow down due to the gravitational force pulling them back together. But the opposite is happening.

What we observed is that instead of slowing down, everything is speeding up and accelerating away from each other, Troxel said. This is like throwing a ball up in the air and instead of having it fall back down, it starts shooting up faster and faster.

Since the acceleration is inexplicable through gravity from massive objects, scientists have concluded that there must be another force or component of the universe at play. In fact, this other component of the universe makes up 70 percent of the dynamics of the universe, Troxel said. It is also invisible to observation, but through gravitational lensing, Troxel and his colleagues can use data from the Rubin and other telescopes to learn more about it.

With the funding from his Department of Energy Award, Troxel said he will be able to hire another graduate student and postdoc to support Dukes cosmology research, which also includes professors Dan Scolnic and Chris Walter, expanding the departments recent focus on the field. One of the benefits for students is that they will have the opportunity to visit the observatory in Chile as the commissioning of Rubin starts.

Its those opportunities to support future scientists that are most meaningful to Troxel. A first-generation student, Troxel credits those who supported his career for his current success. My path to where I am now was not easy, and I only made it due to the support of my teachers and mentors, he said.

But he also hopes to welcome a more diverse group of students into cosmology. It was only last week [with the US Supreme Court ruling on Title VII], for the first time in my life, that I am protected at the national level from being fired from my job solely for who I am, said Troxel, who is LGBTQ.

The story of modern physics and cosmology has been one of turning around our perspectives and viewing the physical world in a new light, leading to fundamental new insights about how the world works, he added. Physics and cosmology benefit from new and diverse perspectives, but we must ensure that the field is worthy of those new voices. The most rewarding part of my role now as a teacher at Duke is to help make sure the next generation of diverse voices are heard and supported while they find their own paths to grappling with the mysteries of the universe.

How Galaxies Die: New Insights Into Galaxy Halos, Black Holes, and Quenching of Star Formation – SciTechDaily

A simple model explains a wide range of observations by describing a contest between galaxy halos and their central black holes that eventually turns off star formation.

Astronomers studying galaxy evolution have long struggled to understand what causes star formation to shut down in massive galaxies. Although many theories have been proposed to explain this process, known as quenching, there is still no consensus on a satisfactory model.

Now, an international team led by Sandra Faber, professor emerita of astronomy and astrophysics at UC Santa Cruz, has proposed a new model that successfully explains a wide range of observations about galaxy structure, supermassive black holes, and the quenching of star formation. The researchers presented their findings in a paper published on July 1, 2020, in the Astrophysical Journal.

The model supports one of the leading ideas about quenching which attributes it to black hole feedback, the energy released into a galaxy and its surroundings from a central supermassive black hole as matter falls into the black hole and feeds its growth. This energetic feedback heats, ejects, or otherwise disrupts the galaxys gas supply, preventing the infall of gas from the galaxys halo to feed star formation.

The idea is that in star-forming galaxies, the central black hole is like a parasite that ultimately grows and kills the host, Faber explained. Thats been said before, but we havent had clear rules to say when a black hole is big enough to shut down star formation in its host galaxy, and now we have quantitative rules that actually work to explain our observations.

The basic idea involves the relationship between the mass of the stars in a galaxy (stellar mass), how spread out those stars are (the galaxys radius), and the mass of the central black hole. For star-forming galaxies with a given stellar mass, the density of stars in the center of the galaxy correlates with the radius of the galaxy so that galaxies with bigger radii have lower central stellar densities. Assuming that the mass of the central black hole scales with the central stellar density, star-forming galaxies with larger radii (at a given stellar mass) will have lower black-hole masses.

What that means, Faber explained, is that larger galaxies (those with larger radii for a given stellar mass) have to evolve further and build up a higher stellar mass before their central black holes can grow large enough to quench star formation. Thus, small-radius galaxies quench at lower masses than large-radius galaxies.

That is the new insight, that if galaxies with large radii have smaller black holes at a given stellar mass, and if black hole feedback is important for quenching, then large-radius galaxies have to evolve further, she said. If you put together all these assumptions, amazingly, you can reproduce a large number of observed trends in the structural properties of galaxies.

This explains, for example, why more massive quenched galaxies have higher central stellar densities, larger radii, and larger central black holes.

Based on this model, the researchers concluded that quenching begins when the total energy emitted from the black hole is approximately four times the gravitational binding energy of the gas in the galactic halo. The binding energy refers to the gravitational force that holds the gas within the halo of dark matter enveloping the galaxy. Quenching is complete when the total energy emitted from the black hole is twenty times the binding energy of the gas in the galactic halo.

Faber emphasized that the model does not yet explain in detail the physical mechanisms involved in the quenching of star formation. The key physical processes that this simple theory evokes are not yet understood, she said. The virtue of this, though, is that having simple rules for each step in the process challenges theorists to come up with physical mechanisms that explain each step.

Astronomers are accustomed to thinking in terms of diagrams that plot the relations between different properties of galaxies and show how they change over time. These diagrams reveal the dramatic differences in structure between star-forming and quenched galaxies and the sharp boundaries between them. Because star formation emits a lot of light at the blue end of the color spectrum, astronomers refer to blue star-forming galaxies, red quiescent galaxies, and the green valley as the transition between them. Which stage a galaxy is in is revealed by its star formation rate.

One of the studys conclusions is that the growth rate of black holes must change as galaxies evolve from one stage to the next. The observational evidence suggests that most of the black hole growth occurs in the green valley when galaxies are beginning to quench.

The black hole seems to be unleashed just as star formation slows down, Faber said. This was a revelation, because it explains why black hole masses in star-forming galaxies follow one scaling law, while black holes in quenched galaxies follow another scaling law. That makes sense if black hole mass grows rapidly while in the green valley.

Faber and her collaborators have been discussing these issues for many years. Since 2010, Faber has co-led a major Hubble Space Telescope galaxy survey program (CANDELS, the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey), which produced the data used in this study. In analyzing the CANDELS data, she has worked closely with a team led by Joel Primack, UCSC professor emeritus of physics, which developed the Bolshoi cosmological simulation of the evolution of the dark matter halos in which galaxies form. These halos provide the scaffolding on which the theory builds the early star-forming phase of galaxy evolution before quenching.

The central ideas in the paper emerged from analyses of CANDELS data and first struck Faber about four years ago. It suddenly leaped out at me, and I realized if we put all these things togetherif galaxies had a simple trajectory in radius versus mass, and if black hole energy needs to overcome halo binding energyit can explain all these slanted boundaries in the structural diagrams of galaxies, she said.

At the time, Faber was making frequent trips to China, where she has been involved in research collaborations and other activities. She was a visiting professor at Shanghai Normal University, where she met first author Zhu Chen. Chen came to UC Santa Cruz in 2017 as a visiting researcher and began working with Faber to develop these ideas about galaxy quenching.

She is mathematically very good, better than me, and she did all of the calculations for this paper, Faber said.

Faber also credited her longtime collaborator David Koo, UCSC professor emeritus of astronomy and astrophysics, for first focusing attention on the central densities of galaxies as a key to the growth of central black holes.

Among the puzzles explained by this new model is a striking difference between our Milky Way galaxy and its very similar neighbor Andromeda. The Milky Way and Andromeda have almost the same stellar mass, but Andromedas black hole is almost 50 times bigger than the Milky Ways, Faber said. The idea that black holes grow a lot in the green valley goes a long way toward explaining this mystery. The Milky Way is just entering the green valley and its black hole is still small, whereas Andromeda is just exiting so its black hole has grown much bigger, and it is also more quenched than the Milky Way.

Spacewatch: Black holes, comets and key dates – Cosmos

The release of the closest-ever images of the Sun understandably grabbed the headlines this week (you can read Richard A Lovetts report for Cosmos here) but there was other news of note. Here are some announcements that took our fancy.

Astronomers reported watching as a supermassive black holes own corona, the ultrabright, billion-degree ring of high-energy particles that encircles a black holes event horizon, was abruptly destroyed.

The cause is unclear, though they guess it was a star caught in the black holes gravitational pull. Like a pebble tossed into a gearbox, it may have ricocheted through the disc of swirling material, causing everything in the vicinity, including the coronas high-energy particles, to suddenly plummet into the black hole.

The result was a precipitous and surprising drop in the black holes brightness, by a factor of 10,000, in under just one year.

We expect that luminosity changes this big should vary on timescales of many thousands to millions of years, says Erin Kara, from Massachussetts Institute of Technlogy, but in this object, we saw it change by 10,000 over a year, and it even changed by a factor of 100 in eight hours, which is just totally unheard of and really mind-boggling.

Following the coronas disappearance, Kara and colleagues watched as the black hole began to slowly pull together material from its outer edges to reform its swirling accretion disc. In just a few months it was able to generate a new corona, with close to its original luminosity.

Another group of astronomers at the Atacama Cosmology Telescope (ACT) in Chile took a fresh look at the oldest light in the Universe and, combining these observations with a bit of cosmic geometry suggest the Universe is 13.77 billion years old, give or take 40 million years.

The new estimate matches one provided by the Standard Model of the Universe and measurements of the same light made by the Planck satellite. This adds a fresh twist to an ongoing debate in the astrophysics community, says Simone Aiola, from the Centre for Computational Astrophysics in New York.

In 2019, a research team measuring the movements of galaxies calculated that the universe is hundreds of millions of years younger than the Planck team predicted. That discrepancy suggested that a new model for the Universe might be needed and sparked concerns that one of the sets of measurements might be incorrect.

Now weve come up with an answer where Planck and ACT agree, says Aiola. It speaks to the fact that these difficult measurements are reliable.

Journal abstract

Astrophysicists from Russia, South Korea and the US are suggesting that carbon is an indication of how long a comet has been in our Solar System; the less carbon, the longer its been in the proximity of the Sun.

The proof, they say, is the comet ATLAS (C/2019 Y4), which approached the Earth in May but disintegrated, displaying a major outbreak of the carbonaceous particles.

ATLAS was expected to be the brightest comet of 2020, visible from the Earth with a naked eye. However, instead of observing the comet itself, we witnessed its disintegration, says Ekaterina Chornaya, from Russias Far Eastern Federal University.

Luckily, we had begun photometric and polarimetric studies before the process started, and because of that, we are able to compare the composition of the coma before and after the disintegration.

The researchers say the polarimetric response of the particles from Comet ATLAS matches that of one of the brightest comets in the history of Earth Comet Hale-Bopp, or C/1995 O1.

Journal abstract

To finish, a couple of important dates were revealed this week.

The Japan Aerospace Exploration Agency (JAXA) and the Australian Space Agency jointly announced that the Hayabusa2 spacecraft containing samples from the asteroid Ryugu will arrive back on Earth in Woomera, South Australia, on 6 December this year. (You can read our most recent coverage of the mission here).

And NASA announced a new target date of 31 October 2021 for the launch of the James Webb Space Telescope from French Guiana. The ongoing coronavirus COVID-19 pandemic and technical challenges have required a move from the original planned launch in March.

An open letter to Australia’s Education Minister Dan Tehan signed by 73 senior professors – The Conversation AU

This open letter is written in response to the Australian governments proposed reforms to the university sector, announced by Education Minister Dan Tehan on June 19, 2020. The so-called job-ready graduates package seeks to make courses in areas such as science, maths and teaching cheaper to encourage more students to get degrees in what the government sees to be job-growth areas. By contrast, fees for many humanities courses will more than double.

Read more: Fee cuts for nursing and teaching but big hikes for law and humanities in package expanding university places

Dear Minister,

We write regarding the recently proposed changes to Australian higher education funding. We welcome the much-needed intent to boost domestic student enrolments. But the complicated and inconsistent nature of the funding changes and the intent to identify work-relevant qualifications risk further undermining the nations fourth largest export industry at a time the Australian economy can ill afford it.

As laureate researchers spanning a wide range of disciplines in science, technology, engineering and mathematics (STEM), humanities, arts and social sciences (HASS) and other fields, we believe this proposal will bring severe negative national consequences for future university training. It is likely to have the unintentional effect of amplifying inequities in higher education, and will work against the very economic goals it is trying to achieve.

Successive Australian governments have refrained from picking winners in industry, but here we see that approach applied to education precisely at a time when future needs are becoming more heterogeneous and unpredictable.

Bracketing the humanities and social sciences as a category deemed less useful for future employment flies in the face of what we see among leaders in both politics and business. More Liberal frontbenchers, for instance, have received an arts degree than studied economics.

Business leader Jennifer Westacott, Chief Executive of the Business Council of Australia, emphasises the importance of a humanities education and Deloitte Access Economics stresses its value in teaching students to ask innovative questions, think critically for themselves, explain what they think, form ethical constructs and communicate flexibly across a range of perspectives.

Read more: If the government listened to business leaders, they would encourage humanities education, not pull funds from it

The proposed changes reflect an outdated view of both HASS and STEM. Each is concerned with advancing our understanding of the world and providing the intellectual framework and critical thinking skills needed to acquire that understanding.

These will be critical for creating a flexible, responsive workforce in an increasingly diverse economy. In the face of our uncertainty about where future needs will lie, what we can be sure of is that interdisciplinary training will become ever more important.

It is unhealthy for a democratic and inclusive society to make some fields the province of those who can pay more for them.

Different pricing is unhealthy for every academic field: the best outcomes grow from an optimal match between disciplines and the talents and interests of those who want to study them, undistorted by arbitrary price signals.

Even within its own premises, many of the subjects it claims to promote (such as maths) will suffer severe cuts. Universities may be discouraged from offering such subjects, or boost their offerings in fields that are cheaper to teach, to cross-subsidise the more expensive courses.

The recently floated patch of an integrity unit to prevent this would simply increase regulatory burdens and consume resources better spent directly on education.

Complex sets of discipline categories greatly reduce the transparency and efficiency of the system. Energy will needlessly be diverted into defining subjects into or out of categories favoured or disfavoured by the funding model.

Universities need to be able to plan intelligently, delivering world-class education and training in an uncertain 21st century. Well-intended but counter-productive distortions in the funding model will not help.

The national economic impacts of these decisions have not been convincingly worked through.

A forward-looking policy of higher-education funding thus needs to do three things:

1. Avoid complex different policies

These will necessitate increased regulation, while failing to achieve either the diversion of student numbers that are sought, or the social and technological goal of better preparing our students for the future.

The simplest way to achieve this is to reinstate a flat HECS rate a simple way to optimise the match between talent, interest and enrolment without distortions from family wealth, easy to administer, and immune from highly uncertain guesses about future trends.

2. Increase funding to universities in real terms

This will assure the growth in quality and capacity of one of Australias transformative success stories and its fourth greatest export. This should be a real increase, not funded from an arbitrary subset of future students at the outset of their careers in a time of great uncertainty.

We appreciate that the COVID-19 epidemic has put unprecedented pressures on the budget, but the need for greater support to our universities is more necessary than ever during this present time of huge financial stress, caused by the plummeting income of overseas students. Wise investment now will pay huge dividends later in the economic, scientific, social and cultural growth of the nation.

3. Integrate the systems for funding university and vocational education, which have long drifted apart

This will ensure every school-leaver has access to the level of training they need for a successful career. What is really needed is not a vocational approach to university education but a more systematic and thoughtful approach to vocational education.

In the modern economy, all kinds of work, including trades, require a broader range of skills than in the past, including communications and IT skills. We have much to learn here from the success of countries like Germany in integrating these two systems of higher education.

We urge this current piece of legislation be shelved in its current form, and replaced by one that has been drafted after proper consultation with a range of experts in the sector who are able to devise an optimal mechanism for building this vital part of our societys future.

What the pandemic can teach the climate movement – Fast Company

Politicians around the country have taken swift action to address the COVID-19 pandemic. But their all-hands-on-deck reactions have also exasperated climate change activists, who can only dream of the same urgency being applied to the arguably more deadly and far-reaching climate crisis.

But the pandemic does have something useful to teach the climate movement: How the courts might respond to intrusive but life-saving interventions.

Courts have on occasion enabled massive changes in societal structure before politicians were ready to, including school desegregation in Brown v. Board of Education and the more recent ruling on marriage equality. Moreover, judicial decisions have strength: Once legal precedent is established, it can be used by attorneys to shape subsequent cases. Furthermore, that precedent is binding on all courts lower than the deciding court, and highly persuasive to courts in other jurisdictions.

For these reasons, climate attorneys should be paying special attention to three distinct types of COVID-19 lawsuits, which could make the (literal) case for bolder action on climate.

First, the failure-to-protect suits that claim the government isnt doing its job in protecting the most vulnerable. Second, the misinformation suits that claim that media outlets are lying to the public about COVID-19 facts. And third, takings suits that claim government shutdowns are robbing people of property rights without just compensation.

Over the last two months, numerous pandemic-related lawsuits have been filed by civil libertarians and prison reform advocates against correctional authorities all over the country, from Los Angeles County to Kentucky to Connecticut. These suits seek the release of certain incarcerated persons from prisons to reduce their risk of contracting COVID-19. They have been filed on behalf of people held in jails on small bonds for nonviolent crimes, those to be released imminently from prison, and people at high risk of life-threatening complications, including those with autoimmune conditions and the elderly. These plaintiffs generally argue that deliberately putting them at risk of certain, but avoidable, bodily harm violates their Constitutional rights.

The pandemic has something useful to teach the climate movement: How the courts might respond to intrusive but life-saving interventions.

The theory that governments have failed to protect people from known threats has been usedunsuccessfully so farin climate suits. The most notable case is Juliana v. United States, where the plaintiffsmostly childrenclaimed that the federal government failed to protect them against climate change, despite knowing of its dangers. Indeed, the history of warning signs about a warming planet goes back more than a centuryfar longer than we have known of the dangers of COVID-19. Yet so far, the Juliana plaintiffs have failed: The Ninth Circuit recently dismissed their suit. (They have appealed.)

If any COVID-19 lawsuits are successful, the legal precedent created may support a more generalized type-of-harm claim for climate activists in the future.

The theory that misinformation disseminated by news media is actionable in court should also be watched by climate attorneys.

One pandemic-related suit that has received national attention is a complaint brought by a nonprofit against Fox News and several other defendants in Washington state court. The nonprofit alleges that, by misleading viewers about the true impact of the deadly virus, Fox News violated the states consumer protection act and committed the tort of outrage.

Despite overwhelming consensus among scientists that humans are the leading cause of climate change, news outlets often have displayed intentional or reckless disregard for the facts. If courts find disregard for COVID-19 facts to be actionable, perhaps the media will be held to a higher standard and climate activists can combat the denialism that persistently plagues the climate debate.

Several takings suits already have been filed against local and state governments. The plaintiffs include business owners closed by public orders and employees who have lost their jobs as a result. They argue that by forcing businesses to close to slow the spread of COVID-19, governments have violated the takings clause of the 5th Amendment.

Generally speaking, the Fifth Amendment requires governments to compensate those whose property has been taken for public use. This includes not just eminent domain but also regulatory takings. But courts have long held that if a government regulates to prevent a public nuisancefor instance, the spread of a deadly and fast-moving disease compensation will not be required.

So, barring novel arguments that resonate with courts, COVID-19 takings challenges will be unsuccessful. Yet they are still worth watching. If courts reject longstanding interpretations of the 5th Amendment and allow the plaintiffs to obtain compensation for the economic disruptions that they have faced, its time to worry.

In the future, climate activists are near-certain to need courts to uphold far-reaching actions needed to reduce carbon emissions into the atmosphere. These actions could include the shutdown of entire industries, such as fossil fuels or beef cattle, or production bans on certain products, such as gas-guzzling SUVs. Climate action might also involve limitations on energy or water consumption, which could be disruptive to our daily lives. As we have been hearing for decades from scientists, the longer we wait to take action, the more extreme future measures will have to be to save humankind.

We have all learned from the pandemic that changes in behavior can have dramatic and life-saving effects. We have bent the curve of COVID-19 infections, and our stay-at-home strategy appears to have worked, saving tens of thousands of lives. When it comes to climate action, though, individual changes in behavior may not be enough. We may need to turn to the courts. And its important to know how the courts will respond to government action (or inaction) when that time comes.

Its Amazing to Me How Distinctly I Remember Each of These Women – Slate

When we started this project, our goal was to talk to as many of the women in Ruth Bader Ginsburgs Harvard Law School class as possible. My colleague Molly Olmstead and I spent months tracking down the ones who are still alive, and interviewing family members in depth about the women who have passed. But then Justice Ginsburg agreed to speak to us, too. And so in late January, just weeks before the court emptied and went remote, a few colleagues and I headed up the sweeping marble steps of the Supreme Court. While we waited, a pot of tea with a single cup on a saucer was placed on the table across from me. And then, a few minutes later, Justice Ginsburg sat down in front of it. This is a lightly edited transcript of our conversation, focused on her time at Harvard Law School almost 65 years agoand her memories of the nine other women in their class of 500-plus men.

Dahlia Lithwick: When we started this project, I think we thought the nine women in your class would clump together and be like a pack. I was remembering when I started at Stanford Law School, in 1992, thats kind of how it was. But based on my conversations with your classmates, it doesnt seem like that necessarily organically happened.

Ruth Bader Ginsburg: Well for me, I had no time to waste, because Jane was 14 months when I started. So my time was used very efficiently, for classes, for studying after class, then come home at 4 p.m. to take care of Jane. I didnt have time for any socializing, except on weekends. So the only person among the women, for a time, that I was close to was Jinnie Davis. And that continued after law school. Read about Jinnies life, and her memories of Justice Ginsburg.

She was in my section, and she was just a lovely person. She was a Christian Scientist. When Marty had cancer his third year, our second year, she visited him in the hospital a few times, and I was wondering how that would be for her, because I watched her once in class. She was sitting a couple of rows ahead of me and she cut her finger, she had a paper cut, and her finger was bleeding. And I wanted to go over and blot it for her, but she didnt, she just let it

Just bleed onto the desk?

Yeah.

And so you werent sure how she would be when Marty was in the hospital, because

Well, just reacting to a hospital.

Ive heard there was a real dividing line between the women in your class who came with children and spouses, and the women who didnt. Was that your experience, too?

Well, in my first year, I was the only one who was married and had a child. I think Carol, I think she got married. And Alice got married at the end of her first year. So my first year, I was the only married woman in the class. And the only mother, because Rhoda [who was married] took her first year at Penn, and then she was in our second year.

Your classmate Carol describes sitting on the steps and doing crossword puzzles, and she and Flora recalled cooking dinners for the men in law schoolit just seems like they were in a really different world than you were. Read Carols memories of Harvard Law School.

I think thats so. [There was something] called the Radcliffe cooking contest. [One male student] and his roommates decided theyd have a competition, and theyd have a different girl come and cook for them. And at the end of the year, theyd give a prize to the winner of the Radcliffe cooking contest.

Then some of the guys at the law school decided they would take up that idea, but they would use the women in the class instead of the Radcliffe girls.

And this was fun for the women?

I dont know.

There was, in those years, the Harvard Law Wives Club. So most of the women I knew were married to men mostly in Martys class. And I got invited to the Law Wives Association because I was a law wife. But that was to help the wives be supportive of their husbands who were engaged in this intense education at the law school.

Did you feel isolated? I mean, did you feel as though you were having a very singular experience that wasnt really comparable to the other women in your class?

No, I did not feel any lack of companionship. I had Marty, and the people that we socialized with were mainly in his class. And then I was just so engaged all the time, with either law school, or with Jane. I had no time to be lonely. I was just constantly engaged, and it was even more intense my second year, when Marty had cancer.

One thing that was really stunning to hear during these interviews was the way the women had such different paths to Harvard. I think when we undertook this project, we envisioned a bunch of singularly driven, ambitious women who said, Im going to go to law school. And as we talked to either the families or to the women themselves, it turned out that a lot of them were trailing a male law student. There wasnt as much, I think, agency as I expected. Im using the word trailing reluctantly, because I know you went in some measure to be with Marty. But I think I was surprised at how many of the women were following a man.

Yeah. I think an exception to that was Ellie Voss. That was such a tragedy. [Editors note: Eleanor Voss died in a motorized scooter accident in her last year at Harvard.] And you can imagine how a young man who was driving that motorcycle mustve felt. I mean, he eventually came to terms with it, and he married and I hope had a happy life. But I dont think Ellie Voss came to Harvard because she was following a boyfriend. BJ, I dont knowof all the women in the class, I was most impressed with her, because she had been both a model and an actuary. Read BJs story.A very unusual combination. Also, she dated a friend of mine in our class. He was in my study group, Herb Lobel. He went out with both BJ and with Jinnie Davis.

Can we talk about the famous Dean Erwin Griswold story, where the dean asked the women of Harvard Law School why they were there taking the place of a man? I only bring it up because Flora told us that she actually thought he was trying to be helpful to women.

He was trying, he was. Theres a book that you probably saw, its called Pinstripes and Pearls, by Judy Hope. And she has as an appendix on the budget, on what it was going to cost for women to come to Harvard Law School. The cost was fixing up a bathroom in Austin Hall, which, by the way, was always overheated. There was asbestos dripping from the ceiling before we knew that asbestos wasnt good for peoples health.

Anyway, [at the dinner], each of us had an escort. [The dean] arranged for somebody on the faculty to sit next to each of the women. And my escort was a very well-known Columbia Law School professor, Herb Wechsler.

Im told that the escorts, before they came to Griswolds home for dinner, went nearby to Judge [Calvert] Magruders house. Because the dean didnt serve any alcohol, they went there first. There were many good things about Dean Griswold, including his bravery in the McCarthy erain the book he wrote about the Fifth Amendment. But he didnt have a sense of humor, and because he had been a proponent of the admission of women, he wanted to assure the doubting Thomases on the faculty that these women were going to do something worthwhile with their law degrees. So he asked that question, Why are you here occupying a seat that could be held by a man?, because he wanted to be armed with stories from the women themselves, about how they plan to make use of their law degrees, and not just waste this wonderful education they would get.

He didnt have any sense that he was making the women feel uncomfortable about this. I dont know if Flora told you about her answer, but as I remember it, she said, Dean Griswold, there are X number of us. There are 500 of them. What better place to find a man? Read Floras memory of the dinner at Griswolds house.

Can you tell me a bit more about the escorts?

They were just to sit next to us at dinner, and sit next to us when we moved from the dining room to the living room. And [the dean] had the chairs arranged in a horseshoe. So, Herb Wechsler was sitting next to me. In those days I smoked, and Herb was a chain smoker. So I had the ashtray that we were sharing on my lap, and when I got up to say something all the cigarette butts went on the floor, in Griswolds living room. Oh, it was really one of those moments, when you wish you could have a trapdoor to fall through. So I mumbled something about my husband is in the second year of class, and I think its important for a wife to understand her husbands work.

If you could answer it again today in the fullness of knowledge, what would your answer be?

It wasnt a truthful answer when I gave it.

But Id say I went to law school because I wanted to study law. In fact, I took the LSAT before Marty did, although he was a year ahead of me.

There was a story I heard from several of the women that I have to say my jaw hit the floor. They described something called ladies day, where the women in the class had to answer all the questions, and even had to sing on the spot.

The professor notorious for ladies day was Barton Leach. My section, we had no ladies day.

I knew about [Leach] lining them up in the first row, and after ignoring them the whole semester, that one day concentrating all [the] attention [on them]. But I think my classmates were warned by the women in the class ahead, of what they could expect. This is a funny storywhen I was, years later, at Columbia, Billie Jean King had just won her match with Bobby Riggs. One of the professors announced with great glee, Tomorrow in honor of Billie Jean King, were going to celebrate ladies day. And he had no idea what the history of ladies day had been.

Was it deliberate hazing? Or was it meant to be funny? Both Carol and Flora remembered it, the singing, but they both laughed about it. And then after laughing about it, Flora said, That was so degrading. Read Floras recollection of ladies day.

Well there were episodes like that. We had as visitors two people wed been close to in the Army. And I brought the woman to class with me, Jill, and she, far from going to law school, she hadnt even gone to college. So [William] McCurdy, my contracts professor, calls on her, and I stood up and said, Shes my house guest. And he said, Any fool can answer that question. You answer it. And then I got up and told him that he was rude to my guest, and I would answer the question.

Really?

Yes. And he said something about Mrs. Ginsburg being a killjoy.

Did he give you a C-plus in contracts?

No.

Maybe the best teacher I ever had, my first year in law school, was Ben Kaplan. He never, never did anything to wound or offend. He was a master of the Socratic technique, but he always used it in a positive way. So a student would give an answer; he would rephrase it as in You mean

McCurdy was a typical Harvard professor at that time and liked to make students feel uncomfortable.

One of the things that we heard from Alice Vogels family was that she got on Law Review, and then got a letter, We dont have dorms for you. Its only the men who are arriving early who are going to get dorms, and theres no place for you to sleep. Read about Alices experience at Harvard.

The Law Review invitations went out at the end of the first year. So it wasnt a competition, it was just strictly on the basis of grades. Alice was getting married, or she had just gotten married. And she just turned it down, because of her husband.

The dormitory was something else. I had come from Cornell, where the girls had to live in the dorms. That was Cornells excuse for having a 4-to-1 ratiofour guys to every galbecause the boys could live in town, but girls had to live in the dormitory. And I get to the Harvard Law School, and they had no room for the girls in the dorm. It didnt matter to me because I wasnt going to be in the dorm anyway. But that, that was one of the many ironies, that the girls needed to be protected, by being sheltered inside a dorm at Cornell. But at Harvard they had to find their own place to stay.

Another version of this was something we heard about Marilyn Rose: She wanted to be in the public defenders, a group at Harvard, and it was all male, and they were not going to let her in. And so, instead of trying to get herself in, she made sure that the women who came after her could be in the public defenders group. Read more about Marilyn Roses experience at Harvard.

And I think what Im trying to understand iswas that just a function of thats what you did if you couldnt get something, that you made sure the women who came after you got it?

I think you get that sense from Judy Hopes book too, that [the female students] benefited from the women in the class ahead of them. And in turn they wanted the women in the class behind them to have it easier. But most of this, it just came with the territory. We didnt even question it. I dont remember anyone asking to have a womens bathroom put in, in Langdell Hall. We just accepted thats the way it was. [Editors note: The family of Rhoda Solin Isselbacher actually recalled that Rhoda, as the law schools first pregnant student, once stood up in class to demand that the women be allowed to use the mens bathroom. Read that story here.]

And the same thing with the dormitories. They did have housing for married students. Marty had been in service for two years. So there are a number of people in his class who had been called into service at the tail end of the Korean War. And they were coming back to law school, and some of them lived in the apartments for married students. But none of their wives were attending law school.

We heard precious few stories of men who were great allies during that time. A lot of women, by the way, described Marty as a great ally but said they didnt have a lot of men around who were supporting them.

[There were] the two who tried to persuade Alice Vogel twice, at the end of her first year, end of her second year, [to join the Law Review]. John Winston and Frank Goodman. Frank ended up on the University of Pennsylvania law faculty, and he was married to Henry Friendlys daughter Joan Friendly. And John Winston, I dont know what he did, but hes still living, and hes living in New York. But they were very supportive of me, especially on the Law Review. Theyre both very funny fellows.

But then there was another type, there was someone who had been a year ahead of me at Cornell, who assured me that Harvard Law School was a very tough place, and I couldnt rely on a good memory to get me through. So there were those types that sort of resented the womens presence. But most of the people I mean for me, Harvard Law School was not a competitive place that second year. My second year, Martys third, when he was diagnosed with cancer, they rallied round us, his classmates, and they got him through that very trying year. And I had note takers in all of his classes, and members of his class came first to the hospital, and then to home to give him private tutorials.

Marty ended up having the best grades that he ever had in a semester. The semester was 15 weeks, I think he was in class for two weeks. But he had the best teachers, his classmates.

One of the most, Im sure, unsurprising things that Im going to tell you, is that all of these women had a really horrendous time getting jobs. And that the same doors that were closed to you were closed to them, and in many ways their stories track yours. Flora said something that I thought was sweet and wanted you to hear it: She said even after graduation and her father was telling her, Dont even bother to get a law job. Youre never going to get one. Find something else. She would look at you and say, Well, if Ruth Ginsburg cant get a job, then Im going to keep trying. She used you as her kind of marker of, Im not going to give up because this is systemic. She was using the fact that you were struggling to double down her effort. Read more about Floras attempt to get her first job.

There was one woman in Martys class, Nancy Boxley, later Tepper. She did get a job. She got a job with Whitney North Seymours firm. All through law school, I thought that Nancy Boxley from Virginia was in the fox-hunting crowd. It turned out that she was Jewish. She disguised who she was, and thats how she did get a job with a Wall Street firm. But for me, there wasnt a single firm in New York two called me back, I came down to have the interviews, but in the end

And one of the reasons was they were concerned about how their wives would feel about a man working closely with a woman. And it amazed me, because they all had women secretaries, but thats just the way it was.

Now Jerry Gunther [who taught me at Columbia Law School] tells a story that I was not aware of until he wrote it in the Hawaii Law Review. He said when he was in charge of clerkships for Columbia students, that he called every judge in Southern District, all the 2nd Circuit judges. And then he thought he had a good prospect, and that was Judge [Edmund] Palmieri, who had been a Columbia undergraduate and a Columbia Law School graduate. And as Jerry told the story, he said, Give her a chance, and if she doesnt work out, theres a young man in her class whos with a downtown firm, and hell jump in and take over. But if you wont give her a chance, then I will never recommend another Columbia clerk to you.

I thought all along that Palmieri took a chance on me, because he had two daughters, and he was envisioning how he would want the world to be for his daughters. It was not the case. In later years, he did become a big champion of womens opportunities. One of his daughters became a doctor, and he was very incensed about the discrimination that she was encountering, the uncompromising hours she had to work.

But anyway, I went through the clerkship thinking thats why Judge Palmieri took me on. But as Jerry tells the story, Palmieri wasnt resistant to having a woman as a clerk. He had already had one, but he was concerned about Jane, that he might need me and she might be sick.

There were so many women who described just being unbelievably proud of you. Carol talked about it. Its clear you represent so much that she is so proud of, and she sees it as her achievement too. Read more about Carol, who, like Justice Ginsburg, is still a practicing judge.

And then there were some who were, I think, frankly a little jealous. Who felt as though you had support from Marty, you had a loving spouse who put you and your career first. And if theyd had some of those breaks, they may have had a very different life. It was just such a complicated story about what we thought was a simple story of sisterhood, and support, and mutual admiration. While you were in it, did you ever have that sense, that this was a little bit fraught? That it was both competitive and supportive, and it was not uncomplicated?

Well, as I said, I had no time to think about emotions. Rhoda SolinI had no idea that she was ever jealous of me. I mean, that surprised me when you told me that. [Editors note: Prior to the interview, Slate sent Ginsburg some examples of what we had learned about her classmates. Read more about Rhodas familys memories of the relationship between the two women.]

For the women in my class and in Martys class, it was getting that first job that was powerfully hard. If the woman got her foot in the door, she did the job very well, and the second job was not the same hurdle.

What youre finding is these are not flaming feminists, these women, and its just pretty much the same in a book that I hope will before much longer see the light of day. [Former Berkeley Law Dean] Herma Hill Kay wrote many biographies of the 14 women in law teaching across the country who preceded her. She was the 15th woman on any law faculty. And when she died, I think she died in 2017, that manuscript got lost. And I dont know the full story of why it wasnt published earlier, but I was at Berkeley in September, and I encouraged Dean [Erwin] Chemerinskythey were having a celebration of herand I said, if you really want to celebrate her, youll see that her book is published. She spent 10 years writing it, and it tells the story of each of these women, and they have every kind of personality, some shy, some bold.

So there wasnt a type that became the first woman. When I transferred to Columbia, that class was considerably smaller than Harvard. But it had 12 women, including one who has been my friend for life, Nina Appel, who was dean of Loyola Chicago Law School for many years.

The women in my Harvard class I stayed in touch with Jinnie Nordin for many years. In fact, the summer after my second year, we had found an apartment across the street from the place where [Columbia] Law School is now, but we were going to live with Martys parents for the summer. So Jinnie was living in our apartment then. Shes the only one in the class that I stayed in touch with. I heard about Flora every now and then.

Floras a hoot. At the very end of her interview, I said, What should we be telling men? And she said, I just wish men were better. And that was very simple for her. But I love what youre saying, which is some of you were not flaming feminists, and some of you were just having fun, and some of you have gone on to have illustrious careers, and some have not. And that this wasnt a feminist project.

Right.

I interviewed you a couple of years ago, when Glamour made you woman of the year. And I asked, What do you do about young women who are coming up, who look at your life as though its a million years ago, and couldnt happen again? And yet theyre still facing glass ceilings at law firms, and theyre limited in some way. Not limited the way your life was, but limited opportunities and deep frustration about work-life balance. And I feel as though if I were a 1L listening to your story, it would seem like science fiction, so far away and so hard to relate to. And yet, I wonder if you can tell me the parts of what you were seeing at Harvard that are still urgently important for women to focus on.

Its an unconscious bias. Its the expectation. You have a lowered expectation when you hear a woman speaking, I think that still goes on. That instinctively when a man speaks, he will be listened to, where people will not expect the woman to say anything of value. But all of the women in my generation have had, time and again, that experience where you say something at a meeting, and nobody makes anything of it. And maybe half an hour later, a man makes the identical point, and people react to it and say, Good idea. That, I think, is a problem that persists. Some of it is getting over unconscious bias by becoming conscious of it, which I thought Ive told the story about the symphony orchestra many times. People were so sure that they could tell the difference between a woman playing and a man, and when put to the test, when blindfolded, they could not.

Willis Reese was a law professor at Columbia Law School. And he said, theres one thing he regrets about the old days. He said when the class was moving slowly, and you wanted to get a crisp right answer, You called on a woman. She was always prepared. And nowadays, he said, theres no difference, the women are as unprepared as the men.

Thats progress.

One thing that I did feel in law school was that if I flubbed, that I would be bringing down my entire sex. That you werent just failing for yourself, but people would say, Well, I did expect it of a woman. Its like they would say about a woman driver. So I was determined not to leave that impression.

Its Amazing to Me How Distinctly I Remember Each of These Women - Slate

This Century Will See Massive Shifts in the Global Population, Economy, and Power Structure – Singularity Hub

A lot of the predictions we hear about the future involve a hot, crowded planet, one where we need some serious science to figure out how to feed everyone and control rising global temperatures. The UNs population forecast of almost 10 billion people by 2050 is widely quoted, and with it has come much conjecture about what such a world will look like. Where will all those people live? What kind of jobs will they have? What will they eat?

But before we invest too much into preparing for an impending population boom, we should consider some factors that, though often overlooked, could have a massive impact on the worlds population 20, 30, and even 80 years from now. A paper published this week in The Lancet explores the impact on population of factors like fertility, mortality, and migration, and details potential deviations from a heavily-populated future Earth.

On top of forecasting the populations of 195 countries, the study looked at age demographics and the impact they could have on national economies and the global power structure.

Continued global population growth through the century is no longer the most likely trajectory for the worlds population, said the Institute for Health Metrics and Evaluation (IHME) Director Dr. Christopher Murray, who led the research. This study provides governments of all countries an opportunity to start rethinking their policies on migration, workforces, and economic development to address the challenges presented by demographic change.

Here are some of the papers key findings, and what they could mean for the future of our countries, economies, and planet.

The study predicts that the global population will peak at around 9.7 billion, but not until 2064. By the end of the century in 2100, that number will plummet by almost a billion people, to 8.8 billion.

Its a pretty huge fluctuation in 35 years time, especially barring events that would take out a big chunk of people at once, like world wars, natural disasters, or pandemics. According to the research, though, 23 countries will see their populations shrink by more than half, including Japan, Thailand, Italy, and Spain.

The US would reach its projected peak of 364 million people in 2062, then fall to 336 million by 2100. This would make the US the worlds fourth most populous country after India, Nigeria, and China, in that order, followed by Pakistan in fifth place. Chinas population is expected to shrink to 732 million by 2100, while Nigerias is set to explode, more than tripling from its current 206 million to 791 million by 2100. Sub-Saharan Africas total population is also forecast to triple, reaching 3.07 billion by 2100.

The percentage of a countrys population thats of working agedefined by the OECD as 15 to 64has a significant impact on its economy. Its part of why China was able to spur such a massive change in its GDP and poverty rates in just 30 years; high birth rates before the countrys one-child policy meant the opening of Chinas economy coincided perfectly with a huge working-age population. Its also why Japans aging population could be called a demographic time bomb.

The IHME study predicts major shifts in the global age structure, with far more old than young people by 2100; it estimates therell be 2.37 billion people over 65 and only 1.7 billion under 20. Moreover, the countries with the most young people will be those that are currently poorer, and their large working-age populations should accelerate their GDP growth.

IHME Professor Stein Emil Vollset, first author of the paper, said, Our findings suggest that the decline in the numbers of working-age adults alone will reduce GDP growth rates that could result in major shifts in global economic power by the centurys end.

At the moment, tensions between China and the West seem to be mounting, with multiple countries recently moving to ban Chinese companies like Huawei and TikTok; meanwhile, China is steadily advancing in technologies like AI and genetic engineering. The US and China are, in a sense, vying for global dominance, and the international leadership vacuum left by the current US administrations foreign policy isnt helping.

The study predicts China will overtake the US economically by 2035, but if the US maintains a liberal immigration policy, it will go back to having the worlds biggest economy by 2098.

The emphasis on immigration as an economic bolster here is critical. Countries that promote liberal immigration, the paper says, are better able to maintain their population size and support economic growth, even in the face of declining fertility rates.

For high-income countries with below-replacement fertility rates, the best solutions for sustaining current population levels, economic growth, and geopolitical security are open immigration policies and social policies supportive of families having their desired number of children, said Murray.

Its crucial, though, that countries put womens rights, education, and healthcare ahead of population growth; we already saw what happens when a government tries to force women to have as many children as possible, and it wasnt pretty.

According to the paper, the UN uses trends from the past to predict how fertility and mortality will evolve across countries in the future. But it leaves out one huge influencer: the fact that theres not only room for improvement, but improvement is likely.

Though it may not seem like it right nowCovid-19 has thrown a big wrench in all kinds of statistics regarding both the present and the futurehuman well-being has been on a steady upward trajectory for the past couple decades. Infant and maternal mortality are down. Life expectancy is up, and gender equality is progressing. The widespread dissemination of technologies like smartphones, combined with government policies aimed at helping the most vulnerable, are lifting people out of poverty.

These trends are likely to continue and even accelerate, and as further gains are made in gender equality and access to education, one of the biggest knock-on effects well see is fewer babies.

At present, women in poor countries are far more likely than women in rich countries to start having babies young, and to have a lot of them. This is due to cultural factors, like marrying young, as well as lack of education and access to contraceptives. The IHME research accounted for the likelihood that women will continue to have greater access to education and reproductive health services, and as a result will delay childbirth and have fewer kids.

The difference between this studys projections and UN forecasts, then, come mainly from the associated decline in fertility rates. The team predicts that in sub-Saharan Africa there will be 702 million fewer people by 2100 than UN forecasts predict, and over 1 billion fewer in south and southeast Asia.

Despite advances in technology that include bigger agricultural yields, cheaper manufacturing, and closely-linked global supply chains, the resources available to us do have a limit, and fewer people means more resources per person.

Looking again to Chinas example, the country was in part able to achieve its astounding economic growth and decline in extreme poverty due to its one-child policy. The Chinese population grew just 38 percent from 1980 to 2013, while Indias grew by 84 percent and Sub-Saharan Africas by 147 percent in the same time period. Fewer mouths to feed means more food per mouth, more wealth per capita, and more people having their needs met.

This applies on a global scale, too, and the papers authors point out that their forecasts have positive implications for the environment, climate change, and food productionthough they acknowledge the predictions could have negative implications for labor forces, economic growth, and social support systems in the countries with the biggest fertility declines.

Humans are pretty good at adapting, though. Whether learning to stay inside for three months straight to curb the spread of a disease or figuring out how to cope with a smaller working-age population, odds are, well manage. A lot can change between now and the year 2100, but from our current vantage point, having fewer than 10 billion people on Earth doesnt sound too bad.

Paul Andersen: ‘Beyond the wall of the unreal city ‘ – Aspen Times

A twig snaps in the dark woods near my camp. In the stillness of a calm night in the wilderness, its as loud as a gunshot. My ears are attuned to the slightest sound.

Something scratches around in the duff near the fire ring. Wavelets gently lap the shore of the lake. A faint whisper of a breeze stirs the spruce tops. Im fully in the moment and appreciate Ed Abbeys Nature Prayer.

Beyond the wall of the unreal city, beyond the security fences topped with barbed wire, beyond the asphalt belting of the superhighways, beyond the cemented backsides of our temporarily stopped and mutilated rivers, beyond the rage of lies that poisons the air

I am there, in Abbeys sacred place, alone and away from it all. I have found what Ed prescribes: the true world of the deserts, the mountains, the forests, the islands, the shores, the open plains. Go there. Be there. Walk gently and quietly deep within it.

Such was my goal in setting off last week from a trail head half an hour drive from my home on a three-day wilderness solo where Abbey set the tone.

May your trails be dim, lonesome, stony, narrow, winding and slightly uphill. May Gods dog serenade your campfire, may the rattlesnake and the screech owl amuse your reverie. May the Great Sun dazzle your eyes by day and the great Bear watch over you by night.

I dont see anyone for three days, yet I have plenty of company with my restive mind. In stillness, the brimming subconscious issues a flood of thoughts that bubble up randomly. Solitude affords communion with something bigger, as Thoreau discovered at Walden Pond: How could I be lonely; is not our planet part of the Milky Way?

John Muir became an accomplished soloist during his thousand-mile walk. Muir exulted while clinging ant-like to the swaying top of a 100-foot tree during a raging storm. He displayed his singularity by dancing a jig before President Teddy Roosevelt on the rim of Yosemite Valley after they had ignited a tall snag into a tower of flame.

Epiphanies of the ages have been instilled in wilderness through Moses, Jesus, Mohammed, Buddha, Elijah. Each had a distinctly personal relationship with solitude in the most profound sense, to which I humbly aspire.

My campfire is the burning bush. My mystic sprites buzz about me in the form of mosquitoes. My animal spirit is in the guise a chattering squirrel scolding this wayward member of the human race.

The rising trout make circles on the lake and remind me of the food chain: Mosquitoes eat me. Trout eat mosquitoes. I eat trout caught with my fly rod. A complete cycle.

I dont fish for fun; I fish for food. As two rainbows simmer in my pan, I give thanks, not to the bounty of nature, but to the fish and game folks who stocked the lake that morning while I ascended the high ridge above the lake. From the tundra, I watched their low-flying plane execute a bombing run with a live slurry of fingerlings.

My ridge hike takes me to a 13,000-foot knob with a 360-view that encompasses one-quarter of Colorados Fourteeners. After a scramble down a couloir to the tundra basin, I rest in the shade of a krummholz stand where I find a wad of wooly white down shed by a mountain goat. I press the soft wool to my nose for an earthy scent of the goat.

That night, I hear the snap of the twig. Within the flimsy shield of my tent I humbly offer myself to whatever night marauder visits my camp. Surrender comes from trusting the benignity of Mother Nature. As her loving son, Im in a place thats far safer than the tumultuous and volatile human world against which Abbey inveighed.

In the bright and sunny morning, I lean back against a log and compose bad poetry. I lift my gaze to watch the lake change complexion and texture as wind/light/shadow alter it from a smooth plate of green glass into corrugations of gray steel.

Im fully in the moment and alive!

United Way’s Days of Action to continue throughout the summer – Herald Review

United Way of 1,000 Lakes hosted the first day of volunteering for its Days of Action initiative on Thursday, July 16. Joined by staff from Days of Action partners, a small group of volunteers came together to complete projects in and around downtown Coleraine. Volunteers began painting fresh parking lines and crosswalks on Roosevelt Avenue, installed wayfinding signs with Get Fit Itasca, and spent time cleaning up and doing light landscaping on the city-owned Old Log Church. Activities in the area also included volunteers from ASV Holdings, Inc., who spent two days clearing the asphalt from Longyear Parks ice rink. This is the first phase of park enhancements that will refurbish the outdoor skate rink, warming house, and park play area.

These projects laid the groundwork for a summer-long, community-wide undertaking to engage community members in improving conditions in the downtown Coleraine neighborhood. In the coming weeks, volunteers will continue to make aesthetic and functional improvements to public spaces in the city, as well as helping homeowners and business owners paint, garden, and complete minor improvements. Working closely with city leadership, the goal of this years Days of Action is to enhance the vibrancy of the citys main street corridor, building a stronger, more connected community in the process.

Days of Action provides an opportunity for residents and cabin owners to give a few hours or even a few days to improve the place where they live, work, and/or play, allowing volunteers to focus on taking positive action in the midst of the health and economic crisis.

I have lived in Coleraine for 44 years and would like to see our little town spruced up, shared Coleraine resident Mary Troumbly about her experience volunteering. I enjoy working on projects that help out others and therefore give me a sense of accomplishment and purpose. I have always loved living here and I think any improvements we can make just make it that much better a place to live.

Days of Action projects take place primarily outdoors, with small groups of volunteers practicing social distancing. Volunteers are screened and required to use protective equipment such as masks and gloves. United Ways next Day of Action will take place on Thursday, July 30, and will include a number of different projects. In particular, United Way is looking for skilled and amateur painters and encourages volunteer groups to take part. Future dates also include Aug. 13, Aug. 27, and Sept. 3. If any of the above dates dont work, individuals and groups can also request a specific date by calling 218-999-7570. Those interested in volunteering can find projects and registration at volunteer.uwlakes.org.

Heart health: Malaysian experts show ways to break vicious cycle of passing unhealthy habits to kids – Malay Mail

Improve your heart health by adopting healthy lifestyle habits. Pexels.com pic

KUALA LUMPUR, July 22 As parenting roles, expectations and demands continue to grow in todays fast-paced lifestyle, Malaysian parents are seen to be highly vulnerable to high cholesterol and heart diseases.

That scenario is even more evident now as the country continues to grapple with heart disease being the leading cause of death in the country.

Highlighting the long-term implications of an unhealthy diet, health experts have warned that the vicious cycle of poor cholesterol management may lead from one generation to another.

According to Institut Jantung Negara (IJN) consultant cardiologist Dr Beni Rusani, poor lifestyle choices are the norm for the new generation of young parents.

Unhealthy eating habits, increased stress levels, sedentary lifestyle and smoking largely as a result of hectic work schedules predispose young parents to high cholesterol and other non-communicable chronic diseases (NCDs).

Heart disease is commonly diagnosed amongst people in the 50-60 age group, but to my point that NCDs do not happen overnight, the groundwork has been laid for at least a good 20 or so years.

In fact, Dr Beni pointed out that the onset of heart diseases in Malaysia is the youngest compared to other countries in the Southeast Asian region.

All the more reason that parents should be concerned about their heart health and high cholesterol from an early stage, he says.

In fighting high cholesterol, prevention is absolutely better than cure, added Dr Beni in a press release.

He said the nature of high cholesterol is often long-term in the making, hence, the longer it is being ignored, the harder it becomes to fix the problem.

Many will argue that prevention is easier said than done, but if parents struggle to find the right motivation, then do it for the sake of their kids.

This is because children tend to copy their parents behaviour.

Dr Beni said parents need to start being better role models and set good examples such as practising a balanced diet and regular exercise for their children to copy.

This way, we can break the vicious cycle of repeating their parents habits even before they become young adults.

It really is common sense and responsible decision-making the qualities of good parenting.

UM Specialist Centre (UMSC) dietetic services head Rozanna M Rosly said it was as easy as starting with improving ones eating habits.

As Malaysians, we cant help but have a healthy appetite and the convenience of fast food, eating out and food deliveries certainly arent making the situation any better.

But taking stock of some of the more positive lifestyle changes that occurred as a result of the recent movement control order, such as home-cooked meals and increased time for family bonding, we are most certainly capable of making heart-healthy choices the new normal, she said.

A heart-healthy balanced diet, according to Rozanna, is not rocket science, nor does it necessitate drastic lifestyle changes.

All it takes is a handful of life hacks that even parents with busy schedules can apply.

She pointed out the Malaysian Healthy Plate a good lifehack to master.

The guide is based on the concept of dividing the regular meal plate into three sections: quarter-quarter-half.

The first quarter is filled with protein such as fish, poultry, meat and legumes) and the second quarter with carbohydrates such as rice, noodles, bread and cereals, while the remaining half is packed with fruits and vegetables.

Emphasis is on the half, as a staggering 95 per cent of Malaysian adults do not consume the recommended daily intake of fruits and vegetables, she said.

Another life hack Rozanna pointed out is food swaps.

You will be surprised by just how many healthier food swap options there are with our everyday Malaysian dishes.

A good rule of thumb is to reduce oily, deep-fried foods and foods that are high in salt, as well as to watch your calorie count, she added.

As for unhealthy eating habits that Malaysians need to start breaking, Rozanna advised parents to reduce the amount of snacking, and instead choose healthier options such as fresh fruits and vegetables.

Keep processed meats and fast foods to a minimum. Watch not only what you eat but also what you drink.

Excessive consumption of carbonated and sugary drinks adds to your calorie count and, according to recent studies, increases the risk of heart diseases as well.

Sean Swarner Leads 18th Climb to Kilimanjaro to Memorialize Those Touched by Cancer – PR Web

CancerClimber Association

DENVER (PRWEB) July 22, 2020

Sean Swarner, 2x cancer survivor, world-record holder, and co-founder of The CancerClimber Association (CCA) will embark on his 18th climb to Mount Kilimanjaro at the end of July with another group of cancer survivors and hikers. Every year, the cohort of CCA climbers will bring a HOPE flag that carries the names of friends and family members who have been touched by cancer. The hikers post the flag at the summit where it remains for thousands of people to see.

The flag is also how you can be a part of the team and a part of the climb. By making a donation you can include the name of a loved one, friend, or anyone you know who has been touched by cancer to this years flag, memorializing them forever on the roof of Africa.

To include a name on the flag, you can donate as little as $1. For those who donate $50 or more, their team will send you a signed photo of their team with the flag at the top of Mount Kilimanjaro. For those who donate $100 or more, they will receive the inclusion of loved ones names on the flag, the signed photo, and a copy of the HOPE flag.

All of us are alive, but not everyone is truly living, says Sean Swarner, Explorer Grand Slam Achiever, World Ironman Championship Competitor, and lifelong adventurer. After surviving cancer twice and learning how fleeting our time is on earth, it has been my greatest joy to now give others the hope that kept me - and continues to keep me - fighting because without hope we have nothing."

Donate and submit the names of those you know who were touched by cancer here:https://charity.gofundme.com/o/en/campaign/climbing-kilimanjaro-for-cancer-2020

Each year prior to the start of the climb, the team raises money for the following year.

human evolution | Stages & Timeline | Britannica

Human evolution, the process by which human beings developed on Earth from now-extinct primates. Viewed zoologically, we humans are Homo sapiens, a culture-bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago. We are now the only living members of what many zoologists refer to as the human tribe, Hominini, but there is abundant fossil evidence to indicate that we were preceded for millions of years by other hominins, such as Ardipithecus, Australopithecus, and other species of Homo, and that our species also lived for a time contemporaneously with at least one other member of our genus, H. neanderthalensis (the Neanderthals). In addition, we and our predecessors have always shared Earth with other apelike primates, from the modern-day gorilla to the long-extinct Dryopithecus. That we and the extinct hominins are somehow related and that we and the apes, both living and extinct, are also somehow related is accepted by anthropologists and biologists everywhere. Yet the exact nature of our evolutionary relationships has been the subject of debate and investigation since the great British naturalist Charles Darwin published his monumental books On the Origin of Species (1859) and The Descent of Man (1871). Darwin never claimed, as some of his Victorian contemporaries insisted he had, that man was descended from the apes, and modern scientists would view such a statement as a useless simplificationjust as they would dismiss any popular notions that a certain extinct species is the missing link between humans and the apes. There is theoretically, however, a common ancestor that existed millions of years ago. This ancestral species does not constitute a missing link along a lineage but rather a node for divergence into separate lineages. This ancient primate has not been identified and may never be known with certainty, because fossil relationships are unclear even within the human lineage, which is more recent. In fact, the human family tree may be better described as a family bush, within which it is impossible to connect a full chronological series of species, leading to Homo sapiens, that experts can agree upon.

Top Questions

Humans are culture-bearingprimates classified in the genusHomo, especially thespeciesHomo sapiens. They are anatomically similar and related to the greatapes (orangutans, chimpanzees, bonobos, and gorillas)but are distinguished by a more highly developedbrain that allows for the capacity for articulatespeechand abstractreasoning. Humans display a marked erectness of body carriage that frees thehandsfor use as manipulative members.

The answer to this question is challenging, since paleontologists have only partial information on what happened when. So far, scientists have been unable to detect the sudden moment of evolution for any species, but they are able to infer evolutionary signposts that help to frame our understanding of the emergence of humans. Strong evidence supports the branching of the human lineage from the one that produced great apes (orangutans, chimpanzees, bonobos, and gorillas) in Africa sometime between 6 and 7 million years ago. Evidence of toolmaking dates to about 3.3 million years ago in Kenya. However, the age of the oldest remains of the genus Homo is younger than this technological milestone, dating to some 2.82.75 million years ago in Ethiopia. The oldest known remains of Homo sapiensa collection of skull fragments, a complete jawbone, and stone toolsdate to about 315,000 years ago.

No. Humans are one type of several living species of great apes. Humans evolved alongside orangutans, chimpanzees, bonobos, and gorillas. All of these share a common ancestor before about 7 million years ago.

Yes. Neanderthals (Homo neanderthalensis) were archaic humans who emerged at least 200,000 years ago and died out perhaps between 35,000 and 24,000 years ago. They manufactured and used tools (including blades, awls, and sharpening instruments), developed a spoken language, and developed a rich culture that involved hearth construction, traditional medicine, and the burial of their dead. Neanderthals also created art; evidence shows that some painted with naturally occurring pigments. In the end, Neanderthals were likely replaced by modern humans (H. sapiens), but not before some members of these species bred with one another where their ranges overlapped.

The primary resource for detailing the path of human evolution will always be fossil specimens. Certainly, the trove of fossils from Africa and Eurasia indicates that, unlike today, more than one species of our family has lived at the same time for most of human history. The nature of specific fossil specimens and species can be accurately described, as can the location where they were found and the period of time when they lived; but questions of how species lived and why they might have either died out or evolved into other species can only be addressed by formulating scenarios, albeit scientifically informed ones. These scenarios are based on contextual information gleaned from localities where the fossils were collected. In devising such scenarios and filling in the human family bush, researchers must consult a large and diverse array of fossils, and they must also employ refined excavation methods and records, geochemical dating techniques, and data from other specialized fields such as genetics, ecology and paleoecology, and ethology (animal behaviour)in short, all the tools of the multidisciplinary science of paleoanthropology.

This article is a discussion of the broad career of the human tribe from its probable beginnings millions of years ago in the Miocene Epoch (23 million to 5.3 million years ago [mya]) to the development of tool-based and symbolically structured modern human culture only tens of thousands of years ago, during the geologically recent Pleistocene Epoch (about 2.6 million to 11,700 years ago). Particular attention is paid to the fossil evidence for this history and to the principal models of evolution that have gained the most credence in the scientific community.See the article evolution for a full explanation of evolutionary theory, including its main proponents both before and after Darwin, its arousal of both resistance and acceptance in society, and the scientific tools used to investigate the theory and prove its validity.

Darwin’s Theory of Evolution: Definition & Evidence | Live …

The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring.

Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology.

The theory has two main points, said Brian Richmond, curator of human origins at the American Museum of Natural History in New York City. "All life on Earth is connected and related to each other," and this diversity of life is a product of "modifications of populations by natural selection, where some traits were favored in and environment over others," he said.

More simply put, the theory can be described as "descent with modification," said Briana Pobiner, an anthropologist and educator at the Smithsonian Institution National Museum of Natural History in Washington, D.C., who specializes in the study of human origins.

The theory is sometimes described as "survival of the fittest," but that can be misleading, Pobiner said. Here, "fitness" refers not to an organism's strength or athletic ability, but rather the ability to survive and reproduce.

For example, a study on human evolution on 1,900 students, published online in the journal Personality and Individual Differences in October 2017, found that many people may have trouble finding a mate because of rapidly changing social technological advances that are evolving faster than humans. "Nearly 1 in 2 individuals faces considerable difficulties in the domain of mating," said lead study author Menelaos Apostolou, an associate professor of social sciences at the University of Nicosia in Cyprus. "In most cases, these difficulties are not due to something wrong or broken, but due to people living in an environment which is very different from the environment they evolved to function in."

In the first edition of "On the Origin of Species" in 1859, Charles Darwin speculated about how natural selection could cause a land mammal to turn into a whale. As a hypothetical example, Darwin used North American black bears, which were known to catch insects by swimming in the water with their mouths open:

"I can see no difficulty in a race of bears being rendered, by natural selection, more aquatic in their structure and habits, with larger and larger mouths, till a creature was produced as monstrous as a whale," he speculated.

The idea didn't go over very well with the public. Darwin was so embarrassed by the ridicule he received that the swimming-bear passage was removed from later editions of the book.

Scientists now know that Darwin had the right idea but the wrong animal. Instead of looking at bears, he should have instead been looking at cows and hippopotamuses.

The story of the origin of whales is one of evolution's most fascinating tales and one of the best examples scientists have of natural selection.

To understand the origin of whales, it's necessary to have a basic understanding of how natural selection works. Natural selection can change a species in small ways, causing a population to change color or size over the course of several generations. This is called "microevolution."

But natural selection is also capable of much more. Given enough time and enough accumulated changes, natural selection can create entirely new species, known as "macroevolution." It can turn dinosaurs into birds, amphibious mammals into whales and the ancestors of apes into humans.

Take the example of whales using evolution as their guide and knowing how natural selection works, biologists knew that the transition of early whales from land to water occurred in a series of predictable steps. The evolution of the blowhole, for example, might have happened in the following way:

Random genetic changes resulted in at least one whale having its nostrils placed farther back on its head. Those animals with this adaptation would have been better suited to a marine lifestyle, since they would not have had to completely surface to breathe. Such animals would have been more successful and had more offspring. In later generations, more genetic changes occurred, moving the nose farther back on the head.

Other body parts of early whales also changed. Front legs became flippers. Back legs disappeared. Their bodies became more streamlined and they developed tail flukes to better propel themselves through water.

Darwin also described a form of natural selection that depends on an organism's success at attracting a mate, a process known as sexual selection. The colorful plumage of peacocks and the antlers of male deer are both examples of traits that evolved under this type of selection.

But Darwin wasn't the first or only scientist to develop a theory of evolution. The French biologist Jean-Baptiste Lamarck came up with the idea that an organism could pass on traits to its offspring, though he was wrong about some of the details. Around the same time as Darwin, British biologist Alfred Russel Wallace independently came up with the theory of evolution by natural selection.

Darwin didn't know anything about genetics, Pobiner said. "He observed the pattern of evolution, but he didn't really know about the mechanism." That came later, with the discovery of how genes encode different biological or behavioral traits, and how genes are passed down from parents to offspring. The incorporation of genetics and Darwin's theory is known as "modern evolutionary synthesis."

The physical and behavioral changes that make natural selection possible happen at the level of DNA and genes. Such changes are called mutations. "Mutations are basically the raw material on which evolution acts," Pobiner said.

Mutations can be caused by random errors in DNA replication or repair, or by chemical or radiation damage. Most times, mutations are either harmful or neutral, but in rare instances, a mutation might prove beneficial to the organism. If so, it will become more prevalent in the next generation and spread throughout the population.

In this way, natural selection guides the evolutionary process, preserving and adding up the beneficial mutations and rejecting the bad ones. "Mutations are random, but selection for them is not random," Pobiner said.

But natural selection isn't the only mechanism by which organisms evolve, she said. For example, genes can be transferred from one population to another when organisms migrate or immigrate, a process known as gene flow. And the frequency of certain genes can also change at random, which is called genetic drift.

Even though scientists could predict what early whales should look like, they lacked the fossil evidence to back up their claim. Creationists took this absence as proof that evolution didn't occur. They mocked the idea that there could have ever been such a thing as a walking whale. But since the early 1990s, that's exactly what scientists have been finding.

The critical piece of evidence came in 1994, when paleontologists found the fossilized remains of Ambulocetus natans, an animal whose name literally means "swimming-walking whale." Its forelimbs had fingers and small hooves but its hind feet were enormous given its size. It was clearly adapted for swimming, but it was also capable of moving clumsily on land, much like a seal.

When it swam, the ancient creature moved like an otter, pushing back with its hind feet and undulating its spine and tail.

Modern whales propel themselves through the water with powerful beats of their horizontal tail flukes, but Ambulocetus still had a whip-like tail and had to use its legs to provide most of the propulsive force needed to move through water.

In recent years, more and more of these transitional species, or "missing links," have been discovered, lending further support to Darwin's theory, Richmond said.

Fossil "links" have also been found to support human evolution. In early 2018, a fossilized jaw and teeth found that are estimated to be up to 194,000 years old, making them at least 50,000 years older than modern human fossils previously found outside Africa. This finding provides another clue to how humans have evolved.

Despite the wealth of evidence from the fossil record, genetics and other fields of science, some people still question its validity. Some politicians and religious leaders denounce the theory of evolution, invoking a higher being as a designer to explain the complex world of living things, especially humans.

School boards debate whether the theory of evolution should be taught alongside other ideas, such as intelligent design or creationism.

Mainstream scientists see no controversy. "A lot of people have deep religious beliefs and also accept evolution," Pobiner said, adding, "there can be real reconciliation."

Evolution is well supported by many examples of changes in various species leading to the diversity of life seen today. "If someone could really demonstrate a better explanation than evolution and natural selection, [that person] would be the new Darwin," Richmond said.
