Things Are Super Weird Right Now, but It’s Not a Glitch in the Matrix, Says Harvard Physicist – ScienceAlert

Posted: March 4, 2017 at 1:32 am

If the past 12 months have you feeling like you're stuck in the beta version of some giant, buggy simulation, we're right there with you, what with the World Series, the Super Bowl, the Oscars, and depending on which side of the fence you sit, the US and UK elections.

But despite what Elon Musk says, the barrage of weirdness we've been experiencing lately is just the way of the Universe, says Harvard theoretical physicist Lisa Randall, who once described the probability that we're living in a giant video game of the future as "effectively zero".

If you're unfamiliar with the simulation hypothesis, it's based in a 2003 paper by Swedish philosopher Nick Bostrom from the University of Oxford, who argued that at least one of the following propositions must be true:

That 'posthuman' stage Bostrom is talking about refers to the probability that at some point in the future, our technology would be so advanced, a single computer could simulate the entire mental history of humankind, using less than one-millionth of its processing power for 1 second.

Now imagine that a posthuman civilisation in the distant future manages to build a massive network of these 'ancestor-simulations', into which we could upload replicas of the minds of our ancestors to play out their lives in a giant computer program.

Assuming these minds had a 'consciousness' - something that scientists have been considering recently - they would realistically demand something akin to human rights so they weren't some kind of robotic slave race. But that's starting to sound a whole lot like us...

In a nutshell,Bostrom proposedthat humans will either almost certainly die out before any of this even happens (thanks, climate change); no advanced civilisations in the history of the Universe contained individuals with the means to build ancestor-simulations; or we almost certainly live in a simulation.

Last year, Elon Musk revealed that he's a big believer in the simulation hypothesis, arguing that "the odds that we're in base reality is one in billions".

And hell, it makes sense when you're going through weird times like these that something other than "base reality" is at play:

But Lisa Randall is here to ruin all our fun, because when Corinne Purtill from Quartz asked her if the recent Oscars mix-up has her rethinking her anti-simulation stance, the answer is not even a little bit.

"At this point, we cannot prove that we do or don't live in a simulation. More to the point, there is no reason to believe that we do," she said.

"However, we can pretty much be sure that people will do amazing things and they will also mess up in spectacular ways."

At a public debate last yearmoderated by Neil deGrasse Tyson, Randall seized on Musk's probability argument as one of the biggest reasons for why the simulation hypothesis doesn't make sense.

"Part of the problem is that probabilities have to have a well-defined meaning, or are only useful when they have a well-defined meaning. So, among all possible scenarios we can actually say which one is more or less likely," she said.

"When we run into infinities ... it stops making sense. I mean, I could say really by probability I'm very likely to be Chinese, because there's a lot more Chinese than Americans. But I'm clearly not Chinese. So, probabilities are tricky, and you have to be careful what you mean when you're saying them."

Randall added that it's incredibly egotistical for us to assume that some highly advanced civilisation would build simulations that look just like us, and the probability argument only works if countless alien civilisations saw the human species as something worth simulating.

"It's just not based on well-defined probabilities. The argument says you'd have lots of things that want to simulate us. I actually have a problem with that," she said.

"We mostly are interested in ourselves. I don't know why this higher species would want to simulate us."

Case closed? Randall thinks so, but there are still some in the simulation corner, including cosmologist Max Tegmark from MIT,who argued, "If I were a character in a computer game, I would also discover eventually that the rules seemed completely rigid and mathematical."

And that sounds an awful lot like laws of physics, asJames Gates, a theoretical physicist at the University of Maryland, pointed out:

"In my research I found this very strange thing.I was driven to error-correcting codes - they're what make browsers work. So why were they in the equations I was studying about quarks and electrons and supersymmetry? This brought me to the stark realisation that I could no longer say people like Max are crazy."

It would be nice to blame all of the recent weirdness on a glitchy simulation, but Randall sayswe're better off coming up with more realistic explanations for the mysteries of the world, rather than blaming it all on a giant computer program.

And that sounds a whole lot more scientific to us.

You can watch the whole debate below, and read the transcript here:

Ascension serves a slice of faith – Forest Lake Lowdown

Posted: at 1:30 am

STILLWATER When Stillwater said arrivederci to downtown restaurant Luna Rossa last year, Ascension Episcopal Church said buon giorno to the businesss wood-fired pizza oven.

The church hopes to set up a food and social ministry by installing the oven at the church office site on Fourth Street in downtown Stillwater.

Reverend Buff Grace said that the church is in the midst of putting a team together to lead the charge to install the oven. There will most likely be a few hurdles to overcome, such as acquiring the proper building permits and making sure the building and oven are in compliance with health codes.

Grace explained that the idea for a pizza oven ministry was inspired by his brother-in-law, Jim Schmitt.

He installed a pizza oven back in the 90s, Grace said. Its been a lot of fun; every time I go over he fires up the pizza oven. He has a flagpole, and whenever the oven is on, he runs a flag up the pole and neighbors know they can bring whatever they want ... Since then weve had a dream of putting a pizza oven in here, and having that space for our congregation and anyone who wants to come in and join us.

It was also through Schmitt that the opportunity presented itself. Schmitt is a collector of antique architecture items, and had arranged to take sconces from the restaurant interior after it closed. He noticed that the pizza oven was still on the site, and learned it might be available.

We talked with the owner and were able to work out a deal, Grace said. It had to be out within a couple of days. We scrambled to get a team to move it out and move it to the church. It was somewhat of a windfall; we didnt have a (project) team together right away, so we wanted to wait until beginning of the new year (to begin planning for the ovens use).

Luckily for Ascension, one of the congregations most recent members is former pastor Bryce Johnson, who spearheaded the installation of a bread oven at United Methodist Church in White Bear Lake.

He has a lot of skills and capacity with this, Grace said. The work that he did was mainly along the lines of bread making. He had done some study in Europe for bread making, so this would be slightly different than what were doing.

Grace said that there has been a large amount of interest from people within the parish.

You say, lets gather a meeting to talk about some of the usual things you would expect in a church, but you say wood-fired oven and people come out of the woodwork, he joked. It stirred up a bunch of interest.

The group discussed the many options for the oven ministry and at this point, plans on an adult fellowship-type of ministry, not that it wouldnt be available for youth and kids, he said. Were seeing that theres a lot of ways to get connected with the church community, and Sunday morning is not necessarily the best avenue for everybody. We think that Christian community is really important, and it doesnt have to be on Sunday morning. This turned out to be a brilliant way to do that.

Grace estimated that the oven might be in use by the end of next summer. He doesnt expect the oven will move far from its current garage location, but hed like to see improvements to the driveway and garage area before everything is complete.

Ascension officials visit Washington DC, want piece of Trump infrastructure pie – The Advocate

Posted: at 1:30 am

DONALDSONVILLE In the days leading up to President Donald Trump's first address to Congress, a large contingent from Ascension Parish government that included Parish President Kenny Matassa, seven of 11 Parish Council members and handful of staffers came to Washington hat in hand.

Specifically, they are seeking a slice of the $1 trillion in infrastructure spending that Trump said he'll be asking Congress to supply.

Council Chairman Bill Dawson said Thursday that parish officials believe Ascension's important role in the nation's energy sector should give it a priority for some of those dollars and made that case to new U.S. Sen. John Kennedy, R- La., and others in Congress.

"If the Trump administration has an infrastructure bill, we think we should get some priorities because we're carrying the load for the energy in the United States," Dawson said during a council meeting in Donaldsonville. "We have a large section of industrial development here. We don't have the roads, the exit roads. We don't have the supply roads that we need to supply those industries."

Trump hasn't yet offered a lot details about where the $1 trillion will come from or how much will go toward traditional public works projects.

The Associated Press reported Wednesday that Republican Pennsylvania Congressman Bill Shuster said billions of that investment could come in the form of planned private sector investment, like pipelines, that is being held up by federal agencies.

Shuster chairs the U.S. House Transportation and Infrastructure Committee. In late January, Congressional Democrats proposed their own $1 trillion, 10-year infrastructure plan with a focus on major public infrastructure projects but left unclear how it would be paid for as well.

Ascension Council Chairman Dawsonmade the announcement as he and other parish officials recapped the large parish delegation's visit to Washington, D.C., over the Mardi Gras weekend and through the middle of the week. They made the stops on Capitol Hill after a weekend National Association of Counties conference in Washington.

He said the visit with Kennedy was among several with federal agencies that affect the parish and other members of the parish's congressional delegation, including U.S. Rep. Garret Graves, R-Baton Rouge, and aides to U.S. Rep. Cedric Richmond, D-New Orleans.

The group also met with U.S. Rep. Clay Higgins, R-Port Barre, who was sworn in to his first term in January.

Matassa said he was able to deliver a letter to the U.S. Army Corps of Engineers that was signed by him and the presidents of four other parishes in the region. In the letter, they indicate their support for construction of the Comite River Diversion Canal, extension of the proposed West Shore hurricane protection levee so it protects St. James and Ascension parishes, and the dredging of Bayou Manchac.

Matassa also pressed for Ascension to get a greater share of federal disaster recovery dollars for the March and August 2016 floods in the next round of funding that state officials are pursuing.

"We would like to see some of those funds come directly to the parish, so we can get going and do what we need to do," Matassa said.

Gov. John Bel Edwards has asked for nearly $4 billion to recover from the floods, but Congress has approved about $1.7 billion. In the first batch of funding, nearly $438 million, Ascension has been projected to receive just a small fraction due to restrictions on the money.

Parish officials also used the D.C. visit to air a few grievances, from the slow pace of permitting by the Corps on major drainage projects to how ozone attainment is enforced in the parish.

Dawson also noted that parish officials aired their complaints with the Federal Emergency Management Agency over their response to the August flood and, in particular, the speed with which residents are receiving their insurance payouts under the National Flood Insurance Program.

"People pay their premiums on time. People pay their taxes on time, but they didn't receive their payments on time," Dawson said.

Blessed Sacrament Huguenot baseball looking to continue VCC ascension – Richmond.com

Posted: at 1:30 am

Last season, the Blessed Sacrament Huguenot Knights finished runner-up in the Virginia Colonial Conference (VCC) and qualified for the Virginia Independent Schools Athletic Association (VISAA) state tournament for the 12th time in the last 16 seasons as the number seven seed.

The season before that, the Knights finished fourth in the VCC.

Every year, weve improved, Blessed Sacrament Huguenot baseball coach James Poore said. Now, its just a matter of putting it all together. Weve got a lot of guys coming back. Weve got some good baseball players.

Coming into the 2017 season, the Knights lost just two seniors from last years team. Tanner Dobrucky, a second team All-VCC selection also departed for Douglas Freeman.

Among the returning players are Carter Davis, who was a first team All-VISAA selection last season, as well as Coleman Smith and James Heldmann, just to name a few.

James Heldmann had a fantastic year pitching, Poore said. He threw a ton of strikes and didnt walk a lot of people. He pitched really good baseball. Hitting wise, you had Coleman do extremely well. Behind the plate, Carter did extremely well. We hit the ball really well.

As a team, Poore said that they hit at over a .300 average last season.

But, he does want to work on the defense side of the ball.

I think we struggled a bit defensively, he said. Were going to work on that a lot, thats something I really want to focus on.

As far as new faces go, Chris Gupton is one player that Poore feels can make an impact this season for the Knights.

He played basketball and football for us, Poore said. (Gupton) played at Hermitage last year. He played the outfield for them. I havent seen him play much, but watching him play other sports, hes a really good athlete and a really good teammate. I think hell be a perfect fit for the team.

Just like last year, the Knights will face some of the best teams in the area when it comes to private school baseball.

Collegiate, the defending Division-I state champions, Steward School and Trinity Episcopal are just some of the teams that Blessed Sacrament Huguenot will face this year.

Were going to play some good people, Poore said. The reason we do that is because I believe that I have some good kids, some good ballplayers. I think it pays dividends at the end of the year when youre facing tougher teams like that.

As far as what Poore would like to see from his team throughout the season, his mantra is simple.

Ive already told the guys this, but theyre goal should be to win every pitch, to win every inning and do that for seven innings, he said. Everything else will take care of itself.

The Knights begin the year on Mar. 15 against Walsingham Academy at 4:30 p.m.

Two Ascension schools to move from host locations following flood – WBRZ

Posted: at 1:30 am

ST. AMANT Two Ascension schools will move from their host sites since the August flood to temporary facilities on Mar. 6.

Lake Elementary will move from host sites Duplessis Primary, Prarieville Middle and the old RPCC campus to temporary buildings on its home campus. St. Amant Primary will move its PreK through second grades from G.W. Carver Primary to the old RPCC campus so the entireschool is on a single site.

Both schools have been at their respective host sites since the August flood. Teachers will move their classroom materials over the weekend in preparationfor the start of school on Monday. According to Ascension Public Schools, parents will receive information about schedules, bus and car drop-off/pick-up and classroom locations.

"This is yet another significant step toward our flood recovery, and we are very appreciative of all the hard work of internal and externalpartners that have madethis happen," said Ascension Public Schools Superintendent David Alexander.

St. Amant High School returned to its campus on Feb. 13 and Galvez Primary returned on Mar. 2 After Lake Elementary and St. Amant Primary's move, the last flooded school to leave a host site will be Galvez Middle.

Horst Simon to Present Supercomputers and Superintelligence at PASC17 in Lugano – insideHPC

Posted: at 1:30 am

Horst Simon, Berkeley Lab Deputy Director

Today PASC17 announced that Horst Simon will present a public lecture entitled Supercomputers and Superintelligence at the conference. PASC17 takes place June 26-28 in Lugano Switzerland.

In recent years the idea of emerging superintelligence has been discussed widely by popular media, and many experts voiced grave warnings about its possible consequences. This talk will use an analysis of progress in supercomputer performance to examine the gap between current technology and reaching the capabilities of the human brain. In spite of good progress in high performance computing and techniques such as machine learning, this gap is still very large. The presentation will then explore two related topics through a discussion of recent examples: what can we learn from the brain and apply to HPC, e.g., through recent efforts in neuromorphic computing? And how much progress have we made in modeling brain function? The talk will be concluded with a perspective on the true dangers of superintelligence, and on our ability to ever build self-aware or sentient computers.

Horst Simon is an internationally recognized expert in the development of parallel computational methods for the solution of scientific problems of scale. His research interests are in the development of sparse matrix algorithms, algorithms for large-scale eigenvalue problems, and domain decomposition algorithms. His recursive spectral bisection algorithm is a breakthrough in parallel algorithms. Honored twice with the prestigious Gordon Bell Prize, most recently in 2009 for the development of innovative techniques that produce new levels of performance on a real application (in collaboration with IBM researchers) and in 1988 in recognition of superior effort in parallel processing research (with others from Cray and Boeing).

Horst Simon is Deputy Laboratory Director and Chief Research Officer (CRO) of Berkeley Labs. The Deputy Director is responsible for the overall integration of the scientific goals and objectives, consistent with the Laboratorys mission. Simon has been with Berkeley Lab since 1996, having served previously as Associate Laboratory Director for Computing Sciences, and Director of NERSC. His career includes positions at Stony Brook University, Boeing, NASA, and SGI. He received his Ph.D. in Mathematics from UC Berkeley, and a Diplom (M.A.) from TU Berlin, Germany. Simon is a SIAM Fellow and member of SIAM, ACM, and IEEE Computer Society.

Dear Editor,

I welcome the news that the Smithsonian Institution will be sending the Apollo 11 command module Columbia on a four-city tour under the title Destination Moon: The Apollo 11 Mission (Fairfax County Times, The history of space travel encapsulated). Our manned and unmanned space exploration programs have set the pace of discovery for decades and achieved remarkable scientific breakthroughs that continue to have countless practical applications in science, engineering, medicine, and follow-on manned space missions.

Nonetheless, without the site survey of NASAs unmanned Lunar Orbiter program (1966-1967) that identified Tranquility Base where Neil Armstrong landed the Apollo 11 lunar lander, there might not have been so many successful manned missions to the Moons surface. Lunar Orbiter reconnaissance missions identified other landing sites as well, making site selection much more accurate and reliable than Earth-based telescopic imaging could. They made possible subsequent landings in more mountainous areas.

I was an active participant in the Lunar Orbiter and Apollo programs (1967-1970) and researched and wrote a history for the NASA Historians Office. In 1977 NASA Headquarters published my book Destination Moon: A History of the Lunar Orbiter Program (NASA TM X-3487) that is available to read on NASAs website at https://history.nasa.gov/TM-3487.

NASAs Langley Research Center in Langley, Virginia managed the program and had five successful orbital missions for five attempts one of the best records of any unmanned program. Following this success Langley managed the 1976 Mars Viking program using much of the technology and experience from Lunar Orbiter.

In preparing for their missions Apollo astronauts studied the detailed photographs that Lunar Orbiters sent back to Earth. Resolution of lunar surface details through the Orbiters 610mm telephoto camera defined details down to one meter in size. Repeated orbital passes over specific target areas made possible stereoscopic pictures of surface features and landing sites that were used in landing simulations by the astronauts.

On August 23, 1966 Lunar Orbiter I took the very first image of the Earth from orbit above the Moon. On August 8, 1967 Lunar Orbiter V photographed the nearly full Earth from polar orbit. These and thousands of other images of the lunar surface, including the dark side of the Moon gave scientists and the public their first true views of the entire surface of Earths natural satellite.

In recent years the original Lunar Orbiter images have been digitized and cleaned up for use in possible future astronaut missions to the Moon. There has been no other orbital survey of the Moon that offers such high quality detail of its surface features.

Teachers attend space exploration conference, bring back lessons out of this world – Arlington Times

Posted: at 1:29 am

ARLINGTON Instructors use some fun ways to teach Earth-based sciences that bring out the natural curiosity in students.

But take those same fields of inquiry into orbit, then let student groups build a tabletop Mars colony project, and their imagination takes flight. After all, the basic science principles are the same whether you apply and test them here on terra firma, or in space. Space is just pun intended cooler.

Two Arlington science teachers are over the moon after attending the Space Exploration Educators Conference at Houston Space Center. They returned with a galaxy of ideas sure to inspire the next generation of scientists and engineers among their students.

Rachel Harrington, sixth-grade science and seventh-grade math teacher at Haller Middle School, and Angie Kyle, a seventh- and eighth-grade STEM teacher at Post Middle School, said the resources they gained were amazing.

It ignites the passion you had when you were a first-year teacher, and thats enough to move mountains with these kids, Harrington said. Youre excited and thrilled to bring this back and inspire kids to do something bigger than their wildest dreams.

Moreover, she added, Youre surrounded by other like-minded educators who also want to inspire future leaders.

Educators from around the globe participated in the annual event at NASAs Johnson Space Center and Space Center Houston for three days in February. The conference welcomed teachers from 41 states and nine countries, including Canada, India, Japan and the Philippines.

The conference included seminars, hands-on activities, tours and guest speakers. The hosts used space exploration initiatives and the latest information about the International Space Program to boost teachers skills in presenting science, technology, engineering and math, or STEM, lessons, in ways that inspire students.

Both Kyle and Harrington have found over time that whenever space science is part of the lesson plan, it gets the students attention.

All the science conducted on the International Space Station connects to all the science we do in middle school, whether growing plants or looking at the impacts of how human systems respond in different environments, Kyle said.

Before Kyle left for the conference to be a pretend astronaut, the class talked about getting a greenhouse. Classroom budgets being tight, she encouraged students to come up with their own proposal. When she returned, the students came up with three inexpensive proposals that used PVC pipe and tarps they just might have a greenhouse before the school-year ends.

For both teachers, this was their first trip the Houston Space Center, but Harrington attended a Honeywell space conference a couple of years ago.

While at the conference, they saw Historic Mission Control Center as well as the space stations flight control room, including stories of what happened during the Apollo days. They also touched moon rocks. Space Center Houston has the worlds largest collection for public view, and more than 400 space artifacts. Their teacher team also successfully designed a Mars rover with mouse traps.

They took their turn in the Neutral Buoyancy Lab, an astronaut training facility operated by NASA near the Johnson Space Center. Their team performed simulated tasks in preparation for an upcoming mission, wearing suits designed to provide neutral buoyancy to simulate the microgravity that astronauts feel during space flight.

A highlight of the visit was meeting astronaut Nicole Stott, a keynote speaker who talked about art in space education. Stott said when growing up nobody told her she could be an astronaut. She went ahead and did it anyway, becoming an engineer first.

Matt Green, James Webb Space Telescope senior staff project scientist, gave a mind-bending presentation on the design and construction of the scope scheduled for completion in 2018. The telescope is expected to see galaxies formed 13.5 billion years ago, at the point when stars and galaxies began to form.

While in Houston, they were able to meet with the planning lead on the NASA Orion Mission, the next generation spacecraft that will carry astronauts to an asteroid, Mars and eventually deep space. Harrington had arranged for her students previously to talk with that person via Skype. She had time to meet with Harrington and Kyle at the conference, but was on her way to meet with the European Space Agency about the project.

A challenging workshop that Harrington and Kyle attended was one that involved working to design a heat shield from common materials. This was an activity the teachers were able to bring back as a classroom assignment, using materials to protect an egg from a blow torch.

The teachers have more experiments in store. For example, studying slingshot maneuvers around a planet, using magnets to mimic gravity. Designing a better space toilet, and creating a urine purification system to make the fluid potable.

Kids love gross-out science, Kyle said, jokingly.

Growing tomatoes from seeds and observing their growth to learn more about photosynthesis is a common science project. Add a few seeds in the mix that took a ride in the International Space Station and study the differences now thats a science project.

The students wont know which of their seeds are more earthly and which are from the space station until they start observing them once they are planted, Harrington said.

Thats the fun of inquiry for the students. They need to report back to the program the effects of space on plants.

Harrington likes to remind students that learning never ends.

I tell them that you need to do it for yourself, always personally and professionally, she said. I am constantly searching for ways to grow myself. They should be doing that every day, too, outside the confines of these four walls and fifty-three minutes.

Reviving Frozen Organs: Nanotech May Pave the Way – Live Science

Posted: at 1:29 am

Frozen organs could be brought back to life safely one day with the aid of nanotechnology, a new study finds. The development could help make donated organs available for virtually everyone who needs them in the future, the researchers say.

The number of donated organs that could be transplanted into patients could increase greatly if there were a way to freeze and reheat organs without damaging the cells within them.

In the new work, scientists developed a way to safely thaw frozen tissues with the aid of nanoparticles particles only nanometers or billionths of a meter wide. (In comparison, the average human hair is about 100,000 nanometers wide.) [9 Most Interesting Transplants]

The researchers manufactured silica-coated nanoparticles that contained iron oxide. When they applied a magnetic field to frozen tissues suffused with the nanoparticles, the nanoparticles generated heat rapidly and uniformly. The tissue samples warmed up at rates of up to more than 260 degrees Fahrenheit (130 degrees Celsius) per minute, which is 10 to 100 times faster than previous methods.

The scientists tested their method on frozen human skin cells, segments of pig heart valves and sections of pig arteries. None of the rewarmed tissues displayed signs of harm from the heating process, and they preserved key physical properties such as elasticity. Moreover, the researchers were able to wash away the nanoparticles from the sample after thawing.

Previous research successfully thawed tiny biological samples that were only 1 to 3 milliliters in volume. This new technique works for samples that are up to 50 milliliters in size. The researchers said there is a strong possibility they could scale up their technique to even larger systems, such as organs.

"We are at the level of rabbit organs now," said study senior author John Bischof, a mechanical and biomedical engineer at the University of Minnesota. "We have a way to go for human organs, but nothing seems to preclude us from that."

However, this research will likely not make it possible to return frozen heads back to life anytime soon, if ever, the scientists noted.

Since the first successful kidney transplant in 1954, organ transplantation has saved the lives of hundreds of thousands of patients. If it weren't for the large and growing shortage of donor organs, the life-saving procedure might help even more people. According to the U.S. Organ Procurement and Transplantation Network, more than 120,000 patients are currently on organ-transplant waitlists in the United States, and at least 1 in 5 patients on these waitlists die waiting for an organ that they never receive.

Right now, the majority of organs that could potentially be used for transplants are discarded, in large part because they can only be safely preserved for 4 to 36 hours. If only half the hearts and lungs that are discarded were successfully transplanted, the waitlists for those organs could be eliminated in two to three years, according to the Organ Preservation Alliance.

One way to save donated organs for transplantation is to freeze them. Ice crystals that can damage cells typically form during freezing, but in prior work, researchers have found a technique known as vitrification which involves flooding biological specimens with antifreeze-like compounds that could help cool down organs to stave off decay, while also preventing the formation of ice crystals.

Unfortunately, ice crystals can also form during the reheating process. Moreover, if thawing is not uniform across samples, fracturing or cracking may occur. Although scientists had developed methods to safely use freezing-cold temperatures to "cryopreserve" tissues and organs, they had not yet developed a way to safely reheat them. [5 Amazing Technologies That Are Revolutionizing Biotech]

In future research, scientists will attempt to transplant thawed tissues into living animals to see how well they do. "From my perspective and my collaborators' perspective, there is no reason why that should not work," Bischof told Live Science.

However, the researchers stressed that it was unlikely these findings would apply to the controversial field of cryonics, which seeks to freeze patients or their brains in the hope that future scientists will find a way to safely revive people. "There are huge scientific hurdles ahead of us, and it's rather premature to get into rewarming a whole person," Bischof said.

"Even if you preserved the whole body, the chances that neural pathways established during life were maintained during and after cryopreservation are probably remote," said study co-author Kelvin Brockbank, chief executive officer of Tissue Testing Technologies in North Charleston, South Carolina. "I don't think we'll see success for rewarming whole bodies within the next hundred years."

The scientists detailed their findings online March 1 in the journal Science Translational Medicine.

L. Gopalakrishnan, Managing Trustee of PSG Sons and Charities is seen in the picture . | Photo Credit: S. Siva Saravanan With efforts to encourage commercial production of innovative products in areas such as biotechnology, internet of things, and nano technology, about 30 % companies at the technology business incubators in the country are in such high-end technologies, Harkesh Mittal, advisor and head of National Science and Technology Entrepreneurship Development Board (NSTEDB), told presspersons here on Monday. He inaugurated here the PSG Nanotech Research, Innovation, and Incubation Centre, which is a collaboration of the PSG Institute of Advanced Studies, PSG College of Technology, and PSG-STEP and is supported by the NSTEDB. This is the only incubation centre so far for nano technology and it will focus on smart textiles, healthcare, renewable energy, and plastic electronics. The area of nano technology is new and lot of research is happening in this field. There is a need for transfer of technology, taking ideas to the market. The incubator will support such an effort, he said. The NSTEDB aims to start 20 new technology business incubators every year in different verticals. There are 110 technology business incubators in the country and 50 of these give seed support to the incubatees. The NSTEDB gives ?10 crore to each of these incubators and the amount is disbursed as loan or equity in two to three years. The National Initiative for Developing and Harnessing Innovations was launched last year. Under this initiative, an incubator gets seed support, has the scope to upscale, and will get support to covert ideas into prototypes. PSG STEP will launch shortly an entrepreneurial residential programme. It is among the 10 incubators in the country that will offer fellowship for a year to students who are entrepreneurs. A student can receive up to ?30,000 a month. E...
