Conceptual Martian greenhouse created by team of UC Davis undergraduates in 2019 presented at this year’s ASCE conference – The Aggie – The Aggie
Posted: September 8, 2021 at 10:13 am
Two years after being recognized by NASA for their conceptual design, the team reflects on how this project influenced where they are today
In 2019, a team of eight UC Davis undergraduate students developed a concept for the Martian Agriculture and Plant Science (MAPS) Greenhouse that was selected as a Top 5 Finalist in the 2019 NASA BIG Idea Challenge. Two years later, their ideas continue to circulate as their paper was presented in April 2021 at the American Society of Civil Engineering (ASCE) Earth and Space Conference, while the team members continue to pursue new and varied opportunities.
The conference, which according to their website, aims to bring the experience and knowledge of experts in the aerospace industry together to share and discuss the latest research and engineering techniques that affect the exploration and settlement of space, was originally set to take place in 2020 before being delayed a year by the pandemic.
Fifth-year aerospace science and mechanical engineering double major and MAPS team lead Duha Bader represented the team by presenting the paper at the conference, and she commemorated the opportunity with a recent LinkedIn post where she thanked project mentor and former NASA astronaut Professor Stephen Robinson, as well as her teammates.
Last week, I had the honor of speaking at the annual ASCE Earth and Space Conference 2021 as an Author for the Martian Agriculture and Plant Science (MAPS): A Food Production Solution for Sustainable Human Presence on Mars paper, read Baders post. MAPS introduces a unique method of transforming Martian regolith into arable soil as well as the implementation of a smart irrigation system.
Journey Byland, a UC Davis alumni and soils lead for MAPS, elaborated via email on the content of the technical report originally written to address the challenge of designing a Martian Surface Greenhouse capable of providing enough calories and nutrition for a crew of four astronauts.
While the popular solution was to integrate hydroponics, which according to the U.S. Department of Agriculture is a method of growing plants in a soilless setting by using a nutrient solution root medium, Byland said that their team chose to instead utilize the martian regolith, or soil, to plant the crops.
Lucas Brown, a fourth-year physics major at UC Davis and irrigation lead for MAPS, explained why the team made this decision.
While employing hydroponics is the first and most obvious choice for designing a greenhouse on Mars, I think theres a real benefit in the long term to exploring the use of martian regolith, Brown said via email. One such benefit being that it would allow for a direct utilization of resources present on Mars rather than relying on entirely synthetic systems that have to be brought along with each launch, another such benefit being that it could contribute to soil research that might benefit us here on Earth as we adapt to a changing climate.
Byland explained how they were able to design this concept.
[We] designed a system that would intake Martian regolith, rinse it in water to dissolve out the [toxic] perchlorate salts, and use an electron beam decontamination system to kill any bacteria, Byland said.
As well as having a unique design, another factor that set the team apart was their interdisciplinary approach, as they drew from a wide variety of fields such as agriculture, structural engineering, thermodynamics and more.
We pulled from a huge variety of resources when producing our design: professors with a variety of specialties, friends who grew plants indoors, fellow students majoring in engineering and one majoring in nutrition, online databases about Martian soil composition, textbooks, research articles, etc., said fourth-year aerospace science and engineering major Isabella Elliot via email. I believe that collaboration and consultation are part of the foundation for productive research and design: science is not a solitary discipline, and working alone without input from other specialties can be detrimental to a project.
Elliot offered one example of how collaboration played a part in their project.
One person suggested having the LEDs in our greenhouse turn on and off in succession so as to mimic the movement of the sun across the sky on earth to help plants grow more evenly and produce a more uniform harvest, a concept that never would have crossed my mind but made absolute sense, Elliot said. Working with persons from other fields as an engineer is enormously enlightening, and fundamentally helped our design take shape and thrive.
Brown had a similar appreciation for the role of interdisciplinary science in their project.
Engineering and design projects like this are inherently interdisciplinary, as there are just so many different problems to solve and constraints to work with, Brown said. Not only did we have to think up ways to sustain a crews food supply for multiple years in a small and isolated environment, but we had to consider the many limitations on that design that come with launching hardware on top of a rocket, through interplanetary space, and later deploying it remotely on the surface of a hostile planet where temperatures reach far below anything seen on Earth.
However, he also emphasized the importance of niche research and specialists, explaining that throughout the project their team both consulted specialists in specific areas and delegated research responsibilities to different individuals on the team.
It helps to have a wide array of people working on that problem and communicating about it, all employing different areas of expertise, Brown said. I know personally Im a huge advocate for breaking down barriers between disciplines for this very reason. One of the things Ive been thinking a lot about these days is trying to increase open collaboration between the sciences and non-STEM disciplines like philosophy or sociology to ensure the scientific community continues to make progress and employ creativity while also being self-reflective about things like methodology and social responsibility.
Both Elliot and Brown considered what theyve learned since the MAPS project that would influence them to approach the problem differently if they were working on it today.
Now that some time has passed and I have more technical experience, my repertoire for problem solving has expanded greatly and I imagine that my approach to problems would be more methodical and less sporadic, Elliot said. More than anything, I would know where to start looking for answers when difficult questions come up.
Brown talked about what perspective the past two years have given him as far as overlooked but essential aspects of space travel design.
I [] wouldve spent some more time thinking about the role of our greenhouses interior design as being a psychological aid to the astronaut crew, Brown said. While this was definitely given some thought in our design, I am coming to increasingly realize that a Martian voyage is likely to be extremely taxing on a human level, and a lot of focus needs to be given to how living spaces like our greenhouse are designed to maximize crew comfort if such a mission is to be successful. We are really only beginning to understand the psychological effects of a human transition into long-term space travel ventures.
Several members of the team also described where they are now, how the early years of their college experience got them to where they are today and what their plans are looking forward.
Byland graduated with a Bachelors of Science in physics this June, and is starting graduate school this fall at the UC Davis Physics Department as a PhD student, currently studying experimental condensed matter physics.
Elliot, an English major upon starting college, solidified her interest in aerospace through working on the MAPS project and is currently working with a professor on hybrid electric aircraft power generation, hoping to work in the future toward designing sustainable air and space craft.
Its always nice to look back on that project, Elliot said. It was one of the most influential parts of my college career so far and Im proud of the work my team and I produced.
Jackson Liao, a fourth-year aerospace engineering major on the team who was always passionate about space exploration, similarly had his interests solidified through the experiences and the connections that the NASA BIG Idea Challenge offered him.
Being able to be at the forefront of new ideas for the purpose of space exploration gave me an even deeper appreciation of the technicality, challenges, and creativeness that comes with developing new technology for space, Liao said.
As for Brown, he came to the realization after the competition was over that he wanted to pursue physics rather than aerospace engineering; he found himself gravitating toward abstract problems, especially as they are related to space and the universe. He now aims to attend graduate school for physics in the future and has aspirations for research in one of several space-based fields.
I think in part due to this project, Im also increasingly interested in the intersection of physics and engineering with other disciplines from philosophy to sociology and politics, Brown said. When working on projects like this that require you to think about the future of technology and humanitys presence in space, I think its important to really think big, making sure youre questioning foundational assumptions along the way, so you can make sure that future youre helping to shape is truly a better world for everyone in it. So these are all definitely ideas that Ill be taking with me as I go forward in my career.

Return trip to Earth is like ‘a series of car crashes,’ says astronaut – CNET
Posted: at 10:13 am
The Soyuz MS-04 spacecraft touched down in Kazakhstan on Sept. 3, 2017, with NASA astronaut Jack Fischer on board.
Four years ago, Jack Fischer -- a now-retired NASA astronaut -- came back to Earth from the International Space Station with a ride in a Russian Soyuz spacecraft. Fischer is reliving his experiences on Twitter, and the posts show just how rough it is to get home from space.
The video shows Fischer, NASA astronaut Peggy Whitson and Roscosmos cosmonaut Fyodor Yurchikhin tucked into their Soyuz seats in 2017. It's three minutes of shakes, rattles and bumps with time-lapse sections of the reentry and landing.
Unlock the biggest mysteries of our planet and beyond with the CNET Science newsletter. Delivered Mondays.
"Some astronauts compare it to a series of car crashes... and I wouldn't disagree," Fischer tweeted.
We're used to seeing images of astronauts on the ISS floating calmly around in microgravity. Fischer's inside-the-capsule video gives us a very different view of the astronaut experience. It's not all pizza parties and space-gardening.
Fischer also shared a stunning short video with a window view of reentry. "I came home from space four years ago this week, and if you've ever wondered what it looks like when you travel through this atmosphere -- here you go," Fischer said.
Fischer spent over nine years with NASA before returning to the US Air Force in 2018. While the ride from space to might have been on the bumpy side, he seems to be looking back fondly on his time traveling between orbit and Earth.

We Think CF Industries Holdings (NYSE:CF) Can Stay On Top Of Its Debt – Simply Wall St
Posted: at 10:13 am
Some say volatility, rather than debt, is the best way to think about risk as an investor, but Warren Buffett famously said that 'Volatility is far from synonymous with risk.' So it might be obvious that you need to consider debt, when you think about how risky any given stock is, because too much debt can sink a company. Importantly, CF Industries Holdings, Inc. (NYSE:CF) does carry debt. But the more important question is: how much risk is that debt creating?
Debt and other liabilities become risky for a business when it cannot easily fulfill those obligations, either with free cash flow or by raising capital at an attractive price. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. However, a more usual (but still expensive) situation is where a company must dilute shareholders at a cheap share price simply to get debt under control. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.
See our latest analysis for CF Industries Holdings
As you can see below, CF Industries Holdings had US$3.71b of debt at June 2021, down from US$3.96b a year prior. However, it also had US$777.0m in cash, and so its net debt is US$2.94b.
Zooming in on the latest balance sheet data, we can see that CF Industries Holdings had liabilities of US$643.0m due within 12 months and liabilities of US$5.41b due beyond that. On the other hand, it had cash of US$777.0m and US$401.0m worth of receivables due within a year. So its liabilities total US$4.87b more than the combination of its cash and short-term receivables.
This deficit isn't so bad because CF Industries Holdings is worth US$9.77b, and thus could probably raise enough capital to shore up its balance sheet, if the need arose. But it's clear that we should definitely closely examine whether it can manage its debt without dilution.
In order to size up a company's debt relative to its earnings, we calculate its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and its earnings before interest and tax (EBIT) divided by its interest expense (its interest cover). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.
CF Industries Holdings's net debt is sitting at a very reasonable 1.7 times its EBITDA, while its EBIT covered its interest expense just 4.7 times last year. It seems that the business incurs large depreciation and amortisation charges, so maybe its debt load is heavier than it would first appear, since EBITDA is arguably a generous measure of earnings. We saw CF Industries Holdings grow its EBIT by 8.1% in the last twelve months. Whilst that hardly knocks our socks off it is a positive when it comes to debt. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if CF Industries Holdings can strengthen its balance sheet over time. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.
Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. Happily for any shareholders, CF Industries Holdings actually produced more free cash flow than EBIT over the last three years. That sort of strong cash conversion gets us as excited as the crowd when the beat drops at a Daft Punk concert.
CF Industries Holdings's conversion of EBIT to free cash flow suggests it can handle its debt as easily as Cristiano Ronaldo could score a goal against an under 14's goalkeeper. But, on a more sombre note, we are a little concerned by its level of total liabilities. Looking at all the aforementioned factors together, it strikes us that CF Industries Holdings can handle its debt fairly comfortably. Of course, while this leverage can enhance returns on equity, it does bring more risk, so it's worth keeping an eye on this one. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately, every company can contain risks that exist outside of the balance sheet. For instance, we've identified 2 warning signs for CF Industries Holdings (1 doesn't sit too well with us) you should be aware of.
At the end of the day, it's often better to focus on companies that are free from net debt. You can access our special list of such companies (all with a track record of profit growth). It's free.

Blue Jays: Randal Grichuk needs to be playing every day in CF – Jays Journal
Posted: at 10:13 am
He might not be bringing a lot to the table with his bat for the Blue Jays lately, but Randal Grichuk still needs to be starting in centre field every day down the stretch. Or at least if/until George Springer is able to play on both sides of the ball again.
That might sound like a weird thing to say when you consider that Grichuk has had a very difficult second half of the season with the bat. Over his last 30 games the 30 year old is hitting just .167/.253/.298 after entering the All-Star break hitting .259 with 16 home runs and 57 RBI. As a result, hes slowly but surely started to lose playing time to the growing group of Blue Jays outfielders.
I can understand why Charlie Montoyo might want a little more offence from the position, but over the last few days Grichuk has reinforced why he still needs to start every day. Quite simply, they need his defence up the middle.
On Sunday he made arguably the best catch of his career with the Blue Jays, diving for a ball in the left centre gap and taking away extra bases from Starling Marte in the first inning.
Well never know how that ball dropping in might have changed the game, but it was an early positive in the momentum department for the Blue Jays, and it helped Robbie Ray throw a scoreless first inning. The emerging Cy Young candidate went on to throw 6.2 scoreless while allowing just one hit, and Grichuk certainly helped to keep the line clean.
I wont go as far as saying that Grichuk is a Gold Glove candidate in centre field, or even a premium defender up the middle, but hes proven himself as more than capable at the important spot on the field over the last two seasons. It seems like hes taking things to another level lately as well, and if thats because of a motivation to try and get back to starting full time, then so be it.
When you consider the alternatives in centre, its pretty easy to see that Grichuk is the best option. With all due respect to Teoscar Hernandez and Corey Dickerson, I hope we dont see either of the corner outfielders in centre again in 2021, even if the former has a bit of experience there. Jarrod Dyson is capable of taking over in the late innings, but hes best used as a pinch runner/late-inning defensive replacement anyway, and doesnt offer any more with the bat than a struggling Grichuk.
With the way the Blue Jays lineup has been rolling over the last three games, they can afford to stash Grichuk and his capable glove right near the bottom of their lineup. Their top six will consist of some combination of George Springer, Marcus Semien, Vladimir Guerrero Jr., Bo Bichette, Teoscar Hernandez, and Lourdes Gurriel Jr., and Alejandro Kirk has been hitting well when hes started as well. That means that the Jays can leave Grichuk and whomever is playing third base for the last two spots in the order (at least when Kirk starts), and his power potential that low in the order could still be an asset.
More importantly, the Blue Jays cant afford to give away any outs on the glove side of the game, and Grichuk is their best defender in the outfield. Its not looking like George Springer is going to be able to play defence any time soon, and as long as thats the case, I hope Grichuk is a regular on Montoyos lineup card.

Cystic Fibrosis Therapeutics Market revenue to cross USD 26.6 Bn by 2027 – GlobeNewswire
Posted: at 10:13 am
Selbyville, Delaware, Sept. 08, 2021 (GLOBE NEWSWIRE) --
According to latest report Cystic Fibrosis Therapeutics Market by Treatment Method (Medications, Devices), Distribution Channel (Hospitals, Retail Pharmacies), Regional Outlook, Price Trends, Competitive Market Share & Forecast 2027, by Global Market Insights Inc., the market valuation of cystic fibrosis therapeutics will cross $26.6 billion by 2027. Increasing advancement in therapeutics for the treatment of life threating disorder that damages lungs will boost the market growth.
Growing advancements in therapeutics for cystic fibrosis is one of the key factors that accelerates the market expansion. According to the National Institute of Health, as of 2019, over 30,000 people in the U.S. are living with cystic fibrosis and around 70,000 worldwide. Numerous healthcare organizations support research and development activities to discover new potential therapies for cystic fibrosis treatment. The Cystic Fibrosis Foundation provides funding to pharmaceutical and biotechnology companies for new pharmaceutical products to cure cystic fibrosis and to maintain robust pipeline of therapies for further clinical development.
Request for a sample of this research report @ https://www.gminsights.com/request-sample/detail/5118
The devices segment captured 9% of the cystic fibrosis therapeutics market share in 2020 led by the usage of novel devices for treatment of cystic fibrosis. VibraLung, Aerobika, Flutter device, Cornet, and MetaNeb are some examples of devices that are used in the cystic fibrosis treatment.
The retail pharmacies segment in the cystic fibrosis therapeutics market is projected to witness about 16% growth rate through 2027. Retail pharmacies in developing countries are one of the key sources for availability of medicines. People prefer retail pharmacies due to ease of access, quality of services. Retail pharmacies dispenses the medications to public at cheaper price owing to several discount schemes. For instance, in January 2020, AllianceRx Walgreens Prime announced availability of Trikafta treatment for cystic fibrosis. This strategic move enhanced the retail pharmacies growth in the market.
Latin America cystic fibrosis therapeutics market size was USD 300 million in 2020. Increasing outdoor pollution, changing lifestyle is attributed to the growth of cystic fibrosis disease in region. Rising cases of lung infection in Brazil and Mexico may cause respiratory problems. The current statistical data showcases very low prevalence of cystic fibrosis in countries in Latin America. This is mainly credited to low reporting of cases and lack of availability of CF registries in the region. However, growing awareness about the disease and its treatment options in Latin American countries will spur the regional growth.

The Road to 2030 in the Age of Intelligence – Huawei
Posted: at 10:12 am
On May 11, 1997, IBM's supercomputer Deep Blue caused a sensation throughout the world when it defeated the then world chess champion, Garry Kasparov. It was hard to imagine that Deep Blue was a giant that weighed 1,270 kilograms, had 32 brains (microprocessors), and could perform 200 million calculations per second, with a computing power of 11.38 GFLOPS.
On March 15, 2016, AIphaGo, Google's Go-playing AI, won the final match in a five-part man-machine series of matches against then world Go champion Lee Sedol, beating Sedol four matches to one. According to Sogou CEO Wang Xiaochuan, AlphaGo's computing power is 30,000 times that of IBM's Deep Blue. Todays most powerful modern supercomputers boast hundreds of thousands of times more computing power than Deep Blue. In fact, any laptop has more computing power than Deep Blue, showing how quickly computing power has progressed over the past 20 years.
Kai-Fu Lee said that chess is considered as a standard for testing the level of an AI. Go has 300 more times the possible plays than chess, so if AI can defeat the best human Go players, that indicates that the development of AI has entered a new stage. To many observers, AlphaGo's victory over Lee Sedol heralded the dawn of the AI era. Google's former CEO Eric Schmidt said that no matter who wins the game, it is actually a victory for humans.
Today, AI technology is being widely applied. In the stock market, AI is better at adapting to changes and predicting results than people are. In the news media industry, AI writes faster and makes fewer errors than human writers. In smart manufacturing, more robots are being equipped with sensors and AI capabilities to work with people.
In the healthcare domain, AI-enabled medical equipment has greatly changed the way medical services are delivered and received, improving the well-being of patients at lower cost.
In the logistics domain, intelligent robotic warehousing systems use AI capabilities provided by micro data center facilities both on the cloud and on site to communicate with each other and handle tasks, shortening the time required for order picking to minutes.
Intelligent transportation systems use big data and cloud technology to improve transportation efficiency and reduce environmental pollution by easing traffic congestion and cutting energy consumption.
When COVID-19 broke out, intelligent technology played an active role in pandemic prevention and control, drug development, disease diagnosis and treatment, and more. Intelligent technology gave birth to new ways of working and living, such as cloud conferencing and cloud classrooms, and contributed greatly to resuming production.
Israel, for example, has a very small land area, less than half of the Pearl River Delta in China and 45% of the land is desert. Arable land accounts for only one-fifth of Israel's land area the country is pretty barren. Israel gets only two-thirds as much annual precipitation as China's rainless central and western regions. However, by using big data and AI, Israel has turned itself into a major agricultural exporter. The annual yield of cotton is 7,500 kg per hectare, and the annual yield of citrus fruits can be up to 4.5 tons per hectare.
This is the magic of intelligent technology. The core technologies of the first Industrial Revolution, second Industrial Revolution, and Information Revolution were steam engines, electricity, and computers/semiconductor chips, respectively. Each technological revolution reshaped the industrial landscape and created new industries that characterized the era.
We are now witnessing the Intelligent Revolution led by 5G, IoT, and AI. Intelligent technology will become a new driver of economic growth, a new blue ocean for industry development, and a new engine for the high-quality development of the digital world.
Bill Gates once said that we always overestimate the change that will occur in the next two years and underestimate the change that will occur in the next ten. This is exactly the mistake that many people are making with the Intelligent Revolution. We have overestimated the development speed of intelligent technology in the next two years. However, although 5G cannot meet the requirements of diverse IoT scenarios today, we've perhaps underestimated the changes it will bring in the next decade.
The Intelligent Revolution will bring us both unprecedented opportunities and challenges. We envision that a fully connected, intelligent world is just around the corner. However, the reality is that most current technologies are still far from mature and reliable.
Humanity and the capabilities that weve acquired through the use of current technology does not always mean we can outperform other animals in the natural world. For example, phone cameras have achieved 100x zoom, but theres still a huge gap between camera capabilities and a spiders eyes in terms of detecting the outlines of objects and motion. Therefore, we may learn from spiders to develop cameras that meet the requirements of autonomous driving. An ant's brain only consumes 0.2 mW of power, but can process many activities, like nesting, socializing, fighting, and feeding aphids. Today's deep neural network training in the AI domain is nowhere near as efficient as an ant's brain. If we can learn more about how the ant brain works, the industry may find new types of computing with lower power consumption and higher efficiency.
From a long-term perspective, the ICT industry is facing new challenges in the next 10 or even 20 years, and urgently needs a new round of breakthroughs. "The continuous development of IoT services such as autonomous driving requires ultra-broadband, low latency, and highly reliable computing power," said William Xu, Huawei's Director of the Board and President of the Institute of Strategic Research, at the Huawei Global Analyst Summit 2021. "However, 5G is currently not mature enough to support these diverse IoT scenarios."
Huawei believes that by the next decade, there will be hundreds of billions of connections around the world. Broadband speeds of 10 Gbps will be available for every user. We will see a 100-fold increase in computing power and storage capacity. More than 50% of energy will come from renewable sources. The technologies that power the generation, transmission, processing, and use of information and energy will need to evolve.
Based on these predictions and assumptions, Huawei presented, for the first time, the challenges and research directions it foresees in the next decade.
These nine challenges and research directions are linked to each other. When we try to understand them based on the three pillars of our world matter, energy, and information, the logical relationship among these challenges and research directions will become clearer to us.
Lets consider the challenges of aging populations and accelerating energy consumption. Data shows that global energy consumption is growing at an annual rate of 1.7%. According to report statistics, the pace of energy consumption has increased by 22 times since the 18th century. Currently 85% of the energy comes from non-renewable fossil fuels, while other emerging energy sources are not ready yet to play a major role. Therefore, low-carbon energy, broader electrification of industries, and intelligence are the path to sustainability.
Huawei estimates that by 2030, more than 50% of all energy will come from renewable sources, and more than 50% of cars sold will be electric. By empowering a wide range of industries, ICT has the potential to reduce global carbon emissions by 20% over the next decade. To build an intelligent Internet of Energy to achieve green electricity generation, storage, and consumption, advancements in the following key technologies are required.
First, management technologies. Digital technologies, such as big data, AI, and cloud, need to be integrated with the Internet of Energy to achieve bit-based watt management through an energy cloud and energy network.
Second, control technologies. Power electronics-based energy routers can be used to build intelligent energy network controllers that realize bidirectional energy flow and intelligent energy distribution.
Third, energy storage technologies. New energy storage technologies, including new electrochemical and hydrogen storage mediums, need to be developed for multiple scenarios to meet these growing storage requirements.
Fourth, power electronic technologies. Wide-bandgap semiconductors, including SiC and diamond for medium- and high-voltage applications, and GaN for medium- and low-voltage applications will be needed to make energy components more efficient and compact.
The intelligent era is still in its infancy, but the next ten years promises to bring changes that are more revolutionary than ever imagined. To advance toward the intelligent world of 2030, we need to address a range of challenges, involving connectivity, capacity, protocols, and computing power.
According to William Xu, the nine technological challenges and directions for further research represent what Huawei believes is needed to achieve an intelligent world by 2030: stronger connectivity, faster computing, and greener energy.
With imagination, we can see the future, but with technology, we can get there. In his book The Inevitable, Kevin Kelly argues that there has never been a better day in the whole history of the world to invent something.
At the beginning of the third decade of the 21st century, we can see that the ICT industry is facing tremendous development opportunities and that the world is moving towards digitalization and intelligence. What will the world look like in 2030?
Many of the new technologies we know will reach the tipping point of revolution and penetrate further into every aspect of our lives. The creation and practices of entrepreneurs have shown people what the future can look like. In the future, technologies such as autonomous driving, robotics, IoT, 3D printing, blockchain, and hyper-reality, multi-modal experience will mature and be applied.
Yuval Noah Harari, author of the best-seller Sapiens: A Brief History of Humanity, once predicted that future machines would know you better than you know yourself, because artificial intelligence programs would be learning about you every day, beginning at birth, reading your every email and listening to every beat of your heart. Ultimately, it would be able to help you make better choices about anything, including life-changing decisions like who to marry and when. Heavy manual labor will increasingly be handled by robots, allowing humans to spend more time thinking and with family and friends.
What can we do today to advance toward the intelligent world of 2030? The answer lies in two key concepts technological innovation and trust-based cooperation.
Huai Jinpeng, an academician of the Chinese Academy of Sciences, once argued that choice of a direction and path has become an ability and wisdom. In his view, cooperation and communication are the best choice when facing challenges and confusion in the intelligent era. The right path to intelligent development is to ensure that we are moving in the right direction without being concerned about immediate benefits.
This is in line with Huawei's belief that to meet the needs of human development and solve the problems we face, we need to bring together the wisdom and creativity of all mankind. We must overcome challenges through an open, inclusive, collaborative, and innovative mechanism. We also need to combine industry, academia, research, and applications to address challenges and embrace opportunities with technological innovation.
Examples in this regard include:
Undoubtedly, in terms of the prospect of creating a fully intelligent world by the next decade, the ability to unite the entire industry for collaborative innovation in certain areas of focus will really make a difference. Restoring the normal business order of the semiconductor industry requires rebuilding global trust and collaboration in the global value chain. As William Xu said, we need to integrate industrial challenges and academic insight, then adopt a venture capital mindset to innovate together and build the intelligent world of 2030.
In the current environment, this trust and cooperation will not be easy to restore, but with the powerful vision of an intelligent world to guide us, we believe that humanity is bound to reach a consensus.

Rediscovering life before digital technology, Internet and social media
Walking through the exhibition feels like traveling back in time. For some, it will seem like an unknown life, whereas for others, it will seem familiar.
Exhibited at the historical Muse de Lachine, La vie sans applis invites viewers to take a walk in a space that shows them life without the internet or social media. The exhibition is presented through different sections, which include social media, photos, music, games, e-mail, and more. Its presented in a manner that displays the evolution of these different subjects. Each section also provides three types of information: a historical fact about Lachine, a did you know, and environmental facts.
When entering the room, viewers can see a blue wall to their left, where photographs of people are displayed. Pictures of hockey teams, as well as people fishing, playing tennis or running a marathon, can be admired among many other photographs. Ironically, in todays world, this would be similar to an Instagram or Facebook feed. Perhaps it could also make visitors think of an old family photo album that they peek at once in a while.
When looking at the photo, video and music sections, there are a variety of objects that can be gazed upon. One can see the evolution of cameras, now old relics with different shapes and sizes. In todays world, we are able to instantly take pictures with our cell phones. Still, some take pleasure in using a film camera, waiting with excitement for the shots to be developed. Aesthetically, old-school looks better.
Phonograph records dating from 1923, and an electric and battery operated radio circa 1937 are among other objects seen in the section. Today, theres no need to worry when it comes to music, considering the multitude of apps that allow people the opportunity to listen to whatever they like. The internet has allowed younger generations to discover music from once upon a time, and help older generations look for their favourite older music with a better sound quality.
One downside of todays music devices is streaming. According to an article published in 2019 by Rolling Stone, a researcher from the University of Oslo explored the environmental impact of streaming music and found out that music consumption in the 2000s resulted in the emission of approximately 157 million kilograms of greenhouse gas equivalents.
The exhibition suggests that the audience download and save the music on ones device.Knowing the amount of music we listen to per day, it would be a challenge for everyone to go back to cassettes and vinyl when everything we listen to is on our devices.
The game section of the exhibition displays familiar pastimes, such as a chess board from 1910, cards from the 20th century, lawn bowling balls from the 19th century and more. Though video games appear to have replaced some of these old forms of entertainment, they are still enjoyed by many out there. In all sincerity, game night with your pals at your favourite board game bar is far more exciting.
The exhibition also demonstrates the way information was received in the past, how products were promoted and the way encyclopedia collections were equivalent to todays search engines. Everything that is exhibited in La vie sans applis can be found on a cell phone. Whether you want to use a calculator, look at the world clock, or communicate with distant family members, everything can be done immediately.
Digital technology has shaped the way the world works as everything travels faster than ever. However, it is essential to take a break and recharge by doing an activity that doesnt involve using our cell phones. La vie sans applis encourages the audience to think about the relationship people have with their electronic devices.
In the end, the real question is: would it be possible today to live without them?
La vie sans applis is being displayed at 1 Chemin du Muse every day from 10:00 a.m. to 5:00 p.m. until Oct. 10.

Social Security is running out of money. Heres how to fix it. – The Philadelphia Inquirer
Posted: at 10:12 am
This is the year Social Security starts paying out more than it brings in. Which could become very expensive, for those of us who hope to retire someday.
The pension program for retired workers, their survivors, and the disabled built up a trillion-dollar reserve, back when the economy grew faster, and retirees didnt live so long. But with employers hiring less, and more workers retired, Social Security is selling its big pile of Treasury bonds to keep the checks coming, for a while.
Last Tuesday, the plans trustees warned they expect that money will run out in 12 years. When that happens, under current law, they say Social Security will have to cut payments to retirees, by about one-quarter forget about cost-of-living bumps and survive on what it still collects from workers and their bosses.
For decades, a dwindling pool of workers has been supporting an ever-growing number of baby boomer retirees. COVID-19 has exacerbated trends cutting the number of working people paying into the system, while increasing the number who have left the workforce and begun collecting from it.
All of which means Congress and the president may have to do something painful raise Social Security taxes, or trim payments, hike the retirement age, or do all of these at once. Which they have, in the past: notably in 1983, when President Ronald Reagan joined the Democrats in a deal to boost contributions a little, and slowly raise the age for normal retirement to the current 67, making the system more solvent, at least until that generation of Washington politicians was safely dead.
READ MORE: Social Security fund now expected to be depleted sooner, programs trustees say
Unfortunately, Reagan and Congress were unduly optimistic about the systems future. As Social Security historian Sylvester Schieber points out, the growth in income disparity has thrown an unexpected curveball into the system, as it releases the ultra-wealthy from payments after their incomes exceeds the tax cap (currently $142,800). Removing the cap would produce a gusher of money, but it strikes at the notion that Social Security checks should have some relationship to money paid in.
What to do?
The trustees have posted a lot of suggestions:
Cut yearly increases in Social Security. There are many schemes proposed for doing this, which would affect different retirees in different ways.
Boost the normal retirement age to 69 from the current 67. Raise the early retirement age from 62 to 65, and up the number of years you need to work to qualify. That would reduce stress on the system a lot. But, as the trustee report doesnt add, it would leave millions of current-retirement-age people in the workforce or cut their incomes, creating lots more stress.
Boost payroll taxes. Social Security already collects an amount equal to 12.4% of Americans gross pay, split between workers and bosses. A more realistic 16% would make the system pay for itself into the next century, the trustees estimate.
And yes, that would be hugely expensive. Social Security would end up consuming about $1 for every $6 in workers gross pay. Up from the current $1 for every $8.
Of course, smaller or later-life Social Security checks would also be terrifically unpopular. Which is why changes tend to get made quietly, over time.
Sens. Mitt Romney (R., Utah) and Joe Manchin (D., W.Va.) headed a bipartisan list of colleagues who in April called for a national Social Security fix-it commission of experts, like the one that recommended the 1983 changes, instead of debating what to do on the floors of Congress, under the heat of cameras and the threat of poisonous party politics.
Isnt 12 years a long way off? Whats the hurry?
The longer we wait, the less money the program will have left. Wait until its about to go broke, and the cuts will have to be a lot larger, or the bailout a lot more expensive, or well have to repeat it very frequently. According to Schieber, a former chair of the systems advisory board, another reason for a current predicament is that Congress used to tinker with Social Security quite often, only to lose its nerve after the early 1980s fixes.
Cant we just borrow the money? That might be a way out. But the system is currently barred from deficit funding. To change that would undo another of the guiding and popular principles of the system that it is a pay-as-you-go system, not welfare, but one in which people earned their payments.
Some senators lame-duck Pat Toomey (R., Pa.), for example also still warn that borrowing has a fiscal price. Sooner or later you end up pumping so much money into the economy that you inflate prices, which slows new hiring, makes incomes worth less, and creates pressure for more government help. Indeed, in recent talks, for example to the York Rotarians last month, Toomey has accused the Democrats of using borrowed money to fund ever more ways to make the middle-class more dependent on government help.
Of course, Social Security itself, which Toomey praised among other early 20th-century reforms in that same talk, faced enormous opposition from some conservative Republicans when it was new. Sun Oil Co. boss Joseph Pew even tried to convince professors at Pennsylvanias Grove City College, which his family funded, not to participate in Social Security, on grounds it eased the natural moral pressure that forced people to work and save. (He was disappointed that only two economists agreed and refused payroll deductions.)
Some people would actually benefit if Social Security payments were cut. Notably, winners would include big investment firms, which could count on attracting more savings from the minority of workers who feel they can afford to set aside significant income for retirement.
But not all conservatives opposed Social Security. Friedrich Hayek, a godfather of libertarianism, in The Road to Serfdom, praised worker-funded retirement and insurance plans though he warned that attempts to socialize the cost beyond participants would provoke bitter opposition.
That, of course, is the problem facing Washington today: Who pays for our most expensive benefits not just Social Security, but also Medicare, and highway spending, both of which are also running out of long-term funding? Just the users, so many of whom have less to spare? Or all Americans, including the most successful? How to balance funding and spending, and how to make it fair?
This is the stuff we should expect our candidates for federal office to be addressing, and proposing realistic solutions, many of which we wont like.

Jeff Bezos Ups His Investment in Immortality – The Motley Fool
Posted: at 10:12 am
Peter Thiel once famously said, "death is a problem that can be solved." Jeff Bezos seems to agree.
The world's richest man this week threw more money behind an obsession among some billionaires: the quest to defeat aging. Bezos' horse in the race is Altos Labs, a promising young start-up trying to reverse aging by reprogramming human cells. But his investing track record in the area leaves a lot to be desired.
Altos is banking on biological reprogramming, a technology that rejuvenates cells in a lab, which experts think could eventually help revitalize entire bodies.
The firm emerged out of a series of three-year, $3 million grants to longevity researchers by Yuri Milner, another middle-aged billionaire. When it became evident that a dedicated, well-funded start-up could pursue research more efficiently, Altos was born in the spring of 2021. And the company hasn't stopped growing since, poaching a who's who of the world's top longevity scientists:
Crowded Field: Despite Altos' distinguished personnel and adequate resources, many funded start-ups are already developing reprogramming technology, including Life Biosciences, Turn Biotechnologies, AgeX Therapeutics, and Shift Bioscience. None, however, have thus far produced treatments that advanced to human clinical trials.
Bad Bets: The track record of billionaire-funded firms with lofty goals for human longevity isn't particularly stellar. Bezos and Thiel previously backed Unity Biotechnology, which last year failed its first major study, canceled its main anti-aging program, laid off 30% of its staff, and shifted its focus to ophthalmology and neurology.
Meanwhile, Alphabet's longevity science subsidiary Calico Labs made headlines in 2013 when, similar to Altos, the firm hired elite scientists and lavished them with enormous research budgets. So far, Calico has produced no major breakthroughs and two of its top scientists jumped ship for greener pastures.

A Definitive Guide to Supplements for Healthy Aging – Healthline
Posted: at 10:12 am
Getting older is a process accompanied by changes in many aspects of health.
Not only can aging affect the way you look and feel, but it can also influence the specific nutrients and amounts of them that your body needs.
Fortunately, supplements are available that can make it much easier to meet your nutritional needs to support healthy aging and help keep you feeling your best.
This in-depth guide will explore everything you need to know about supplements for healthy aging.
Your body goes through several changes as you age, many of which can alter your nutritional needs and increase the risk of deficiencies.
For example, your stomach produces less acid, which can reduce your bodys absorption of micronutrients such as vitamins B6 and B12, iron, and calcium. For this reason, adults over 50 may need to take in more of these nutrients (1, 2).
Many older adults also experience reductions in bone mass, which is why calcium and vitamin D requirements are higher for those over age 70 (3, 4).
Adults over age 65 may also need to consume larger amounts of protein to help prevent sarcopenia, or age-related muscle loss (5).
Additionally, postmenopausal women need less iron because they lose less blood once they stop having regular periods (6).
Because many people experience a decrease in appetite as they get older, meeting their nutritional needs can become even more challenging. This is another reason some turn to supplements.
Decreased nutrient absorption, loss of bone mass, muscle loss, menopause, and reduced appetite can all change your nutritional needs as you age.
Supplements arent necessary for everyone. In fact, many people can meet their nutritional needs simply by consuming an overall nutritious, balanced diet.
However, some people may benefit from taking certain supplements.
For example, supplements may be recommended for those who have health conditions that impact nutrient absorption or who take medications that increase the risk of nutritional deficiencies.
People with certain dietary restrictions may also need to take a supplement to meet their nutrient needs.
For instance, vegans and vegetarians may find it more difficult to consume enough iron, vitamin B12, or omega-3 fatty acids because these nutrients are more abundant and easier to absorb in animal foods (7).
Vegans may also experience deficiencies in calcium, iodine, and zinc. Calcium is of particular concern for older adults who may be at risk of osteoporosis.
Individuals who are lactose intolerant should also be mindful of calcium intake. Increasing age is associated with a greater likelihood of lactose intolerance, and an inability to consume dairy products could contribute to a calcium deficiency.
Additionally, vitamin D is not commonly found in food sources, meaning that people who dont get regular sun exposure may require supplementation (4).
Studies show that vitamin D deficiency is common among older adults in assisted living facilities and nursing homes (8, 9).
Still, its best to work with a healthcare professional to determine whether you need supplements or can meet your nutritional needs through diet alone.
While supplements arent necessary for everyone, they can be helpful for older adults who have difficulty meeting their nutritional needs through diet alone.
The following is a list of supplements that may help with certain aspects of aging.
Calcium is an important mineral that plays a key role in bone health (10).
Women are at a higher risk of osteoporosis, or bone loss, as they get older. A calcium supplement may be beneficial to help preserve bone density, especially if youre not consuming enough calcium from foods (11).
Taking vitamin D can help improve your bodys absorption of calcium. Some supplements contain both calcium and vitamin D.
The form of calcium a supplement contains also makes a difference.
Calcium carbonate supplements should be taken with meals to improve absorption. Many older adults take stomach acid reducers, which may prevent adequate absorption of calcium carbonate.
Calcium citrate supplements, on the other hand, are easier to absorb and do not need to be taken with meals.
However, while studies show that increasing your intake of calcium may be linked to increased bone density and decreased bone loss, its unclear whether it can also help prevent fractures (12, 13, 14, 15).
Although calcium is an important factor in bone density, its not the only one. Smoking, not getting enough weight-bearing exercise, and decreases in estrogen and testosterone that occur with age can also negatively affect bone density.
Omega-3 fatty acids are a type of heart-healthy fat known for their ability to fight inflammation (16).
Impressively, some research even shows that omega-3s could slow declines in brain health and protect against conditions such as Alzheimers disease (17, 18).
Whats more, omega-3s may reduce symptoms of osteoarthritis and could aid in the prevention of heart disease (19, 20).
Although you can meet your omega-3 needs by consuming foods like fatty fish, you can also use a supplement such as fish oil, krill oil, or algal oil.
Collagen is a protein found throughout your body, including in your skin, muscles, tendons, and ligaments.
As you get older, your body begins to produce less of it. As a result, some older adults consider adding collagen supplements to their daily routine.
Studies show that collagen supplements can improve skin hydration and elasticity to support healthy skin aging (21, 22).
Collagen may also help reduce symptoms of osteoarthritis, including joint pain and stiffness (23, 24).
Coenzyme Q10, or CoQ10, is an important compound that aids in energy production.
Low levels of CoQ10 have been associated with several health conditions, including heart failure, type 2 diabetes, cancer, and progressive brain conditions such as Alzheimers disease (25).
Because your body tends to produce less CoQ10 as you get older, increasing your intake through foods or supplements is often recommended to help ensure healthy aging and protect against disease (26).
Sometimes called the sunshine vitamin, vitamin D is a fat-soluble vitamin that your skin produces in response to sun exposure (27).
However, because its found naturally in very few food sources, many people are at risk of deficiency (4).
Older adults may also be at risk of vitamin D deficiency because they may avoid sun exposure to reduce the risk of skin cancer or may otherwise spend more time indoors than younger people (4).
Studies show that in addition to boosting the absorption of calcium, vitamin D supplements may help increase muscle mass, enhance immune function, and decrease symptoms of depression, particularly in those with a vitamin D deficiency (28, 29, 30, 31).
B vitamins are involved in multiple aspects of health and are crucial for energy production, DNA repair, immune health, and brain function (32).
Whats more, some research even suggests that a B vitamin deficiency could be linked to a higher risk of cognitive decline, osteoporosis, and heart disease in older adults (32).
While most healthy adults can meet their needs for certain B vitamins, such as folate, riboflavin, and thiamine, by eating a balanced diet, others may require a supplement.
This may be especially important for those who follow restrictive diets or have health conditions that impact nutrient absorption.
Additionally, adults over age 50 may be at an increased risk of vitamin B12 deficiency and should speak with a healthcare professional to determine whether they need a vitamin B12 supplement (33).
Not only do adults over age 65 require higher amounts of protein, but studies show that eating more protein may also be linked to increased muscle mass and improved muscle function for older people (34, 35, 36).
This is partially because adults begin losing muscle mass and strength as they get older, which can increase the risk of falling and make many daily activities more difficult. Protein needs also increase due to a reduction in muscle protein synthesis with age (5, 34).
While not everyone needs a protein supplement, adding a scoop of protein powder to smoothies, pancakes, and baked goods can be an easy and convenient way to bump up your intake.
Several herbal supplements could also be beneficial for healthy aging, including:
Many supplements are available that can support healthy aging by improving bone health, increasing muscle mass, preserving brain function, and protecting against disease.
While certain supplements can be beneficial as you get older, its important to remember that not everyone needs to take supplements.
Furthermore, some products can interfere with medications or cause serious side effects in people with certain health conditions.
For this reason, its best to work with a healthcare professional to determine whether supplements are right for you.
Also, keep in mind that not all supplements are created equal.
Be sure to buy supplements from reputable brands and opt for products that have undergone third-party testing to ensure safety, purity, and quality. Look for a seal on a supplements packaging from a third-party organization such as NSF International, USP, or ConsumerLab.
To get the most bang for your buck, read ingredients lists carefully and steer clear of products with high amounts of sugar, artificial additives, or fillers.
Finally, be sure to use supplements only as directed and talk with a healthcare professional to address any concerns, especially if you experience adverse side effects.
Not everyone needs supplements, and some products may be harmful for those who are taking medications or have certain health conditions. Its also important to buy high quality products from reputable brands and use supplements only as directed.
As you get older, your needs for certain nutrients, such as protein, calcium, vitamin D, iron, and B vitamins, can change.
While not everyone needs supplements, they can be useful for older adults who have difficulty meeting their nutritional needs through diet alone.
Just be sure to buy high quality supplements from a reputable brand, use them only as directed, and talk with a healthcare professional before trying new supplements.
