Slashdot reader the_newsbeagle shares an article from IEEE Spectrum: Many associate XPrize with a $10-million award offered in 1996 to motivate a breakthrough in private space flight. But the organization has since held other competitions related to exploration, ecology, and education. And in November, they launched the Pandemic Response Challenge, which will culminate in a $500,000 award to be split between two teams that not only best predict the continuing global spread of COVID-19, but also prescribe policies to curtail it...

For Phase 1, teams had to submit prediction models by 22 December... Up to 50 teams will make it to Phase 2, where they must submit a prescription model... The top two teams will split half a million dollars. The competition may not end there. Amir Banifatemi, XPrize's chief innovation and growth officer, says a third phase might test models on vaccine deployment prescriptions. And beyond the contest, some cities or countries might put some of the Phase 2 or 3 models into practice, if Banifatemi can find adventurous takers.

The organizers expect a wide variety of solutions. Banifatemi says the field includes teams from AI strongholds such as Stanford, Microsoft, MIT, Oxford, and Quebec's Mila, but one team consists of three women in Tunisia. In all, 104 teams from 28 countries have registered. "We're hoping that this competition can be a springboard for developing solutions for other really big problems as well," Miikkulainen says. Those problems include pandemics, global warming, and challenges in business, education, and healthcare. In this scenario, "humans are still in charge," he emphasizes. "They still decide what they want, and AI gives them the best alternatives from which the decision-makers choose."

But Miikkulainen hopes that data science can help humanity find its way. "Maybe in the future, it's considered irresponsible not to use AI for making these policies," he says.
For the Covid-19 competition, Banifatemi emphasized that one goal was "to make the resulting insights available freely to everyone, in an open-source manner — especially for all those communities that may not have access to data and epidemiology divisions, statisticians, or data scientists."

"As COVID-19 relentlessly infects more and more of us, scientists are getting a close look at the strange and frightening damage it can inflict on our bodies," writes Science Alert (in an article shared by long-time Slashdot reader AmiMoJo): We've known since early in the pandemic this disease wreaks havoc on more than just the respiratory system, also causing gastrointestinal conditions, heart damage and blood clotting disorders. Now, a year into the pandemic, in-depth autopsies of COVID-19 patients have revealed greater details of widespread inflammation and damage in brain tissues. This may help explain the deluge of neurological symptoms that have manifested in some patients, from headaches, memory loss, dizziness, weakness and hallucinations to more severe seizures and strokes.

Some estimate that up to 50 percent of those hospitalised with COVID-19 could have neurological symptoms that can leave people struggling to do even common daily tasks like preparing a meal. "We were completely surprised. Originally, we expected to see damage that is caused by a lack of oxygen," said physician and clinical director at National Institute of Health (NIH), Avindra Nath. "Instead, we saw multifocal areas of damage that is usually associated with strokes and neuroinflammatory diseases...."

Their report was published in the New England Journal of Medicine.
The article also remembers a September remark by a University of Liverpool neurologist to Nature magazine back in September who had also suggested possible neurological symptoms from COVID-19. "We've seen this group of younger people without conventional risk factors who are having strokes, and patients having acute changes in mental status that are not otherwise explained."

The Weather Channel reports: One main reason humans need to get a flu vaccine annually: flu strains mutate regularly so vaccines need to be slightly altered every year. During past flu seasons, the CDC has noted a vaccine effectiveness range between 40-60%, and a reduced the risk of flu-related illness by 40-60% within the overall population. There are, however, several "universal" flu vaccines currently being studied that aim to make annual flu vaccinations a thing of the past. In fact, according to the American Society for Microbiology, some of these vaccine candidates are in phase 2 and phase 3 trials right now.
Now UPI reports: Researchers believe they are one step closer to a "universal" flu vaccine, even as concerns over the seasonal virus move to the back burner during the COVID-19 pandemic. T cells found in the lungs may hold the key to long-lasting immunity against influenza A, the more common and often more severe form of the virus, according to the researchers behind a study published Friday by Science Immunology.

These cells, which the researchers call resident helper T cells, help the body initiate antiviral responses against new influenza strains even after experience with only one type of the virus, the researchers said. This type of "generalized" immune response, against all virus strains, is not possible with the currently available yearly vaccine formulations, they said.

An anonymous reader quotes a report from The Guardian: Genetic differences between identical twins can begin very early in embryonic development, according to a study that researchers say has implications for examining the effects of nature versus nurture. Identical -- or monozygotic -- twins come from a single fertilized egg that splits in two. They are important research subjects because they are thought to have minimal genetic differences. This means that when physical or behavioral differences emerge, environmental factors are presumed to be the likely cause. But the new research, published on Thursday in the journal Nature Genetics, suggests the role of genetic factors in shaping these differences has been underestimated.

[Kari Stefansson, the co-author of the paper and head of Iceland's deCODE genetics] and his team sequenced the genomes of 387 pairs of identical twins and their parents, spouses and children in order to track genetic mutations. They measured mutations that occurred during embryonic growth and found that identical twins differed by an average of 5.2 early developmental mutations. In 15% of twins, the number of diverging mutations was higher. When a mutation happened in the first few weeks of embryonic development, it would be expected to be widespread both in an individual's cells and in those of their offspring.

In one of the pairs of twins studied, for example, a mutation was present in all cells in one sibling's body -- meaning it is likely to have happened very early in development -- but not at all in the other twin. Stefansson said that out of the initial mass that would go on to form the individuals, "one of the twins is made out of the descendants of the cell where the mutation took place and nothing else," while the other was not. "These mutations are interesting because they allow you to begin to explore the way in which twinning happens."

A new theory described today in Scientific Reports posits that hunter-gatherers whose omnivorous digestive system prevented too much protein consumption likely shared surplus meat with wolves. Those scraps may have initiated a step toward domestication. Scientific American reports: [Maria Lahtinen, a senior researcher at the Finnish Food Authority and a visiting scholar at the Finnish Museum of Natural History] did not originally set out to solve a long-standing dog mystery. Instead she was studying the diet of late Pleistocene hunter-gatherers in Arctic and sub-Arctic Eurasia. At that time, around 20,000 to 15,000 years ago, the world was engulfed in the coldest period of the last ice age. In frigid environments then, as today, humans tended to derive the majority of their food from animals. Nutritional deficiencies came from the absence of fat and carbohydrates, not necessarily protein. Indeed, if humans eat too much meat, diarrhea usually ensues. And within weeks, they can develop protein poisoning and even die. "Because we humans are not fully adapted to a carnivorous diet, we simply cannot digest protein very well," Lahtinen says. "It can be very fatal in a very short period of time."

During the coldest years of the last ice age -- and especially in harsh Arctic and sub-Arctic winters -- reindeer, wild horses and other human prey animals would have been eking out an existence, nearly devoid of fat and composed mostly of lean muscle. Using previously published early fossil records, Lahtinen and her colleagues calculated that the game captured by people in the Arctic and sub-Arctic during this time would have provided much more protein than they could have safely consumed. In more ecologically favorable conditions, wolves and humans would have been competing for the same prey animals. But under the harsh circumstances of the Arctic and sub-Arctic ice age winter, sharing excess meat with canines would have cost people nothing. The descendants of wolves that took advantage of such handouts would have become more docile toward their bipedal benefactors over time, and they likely went on to become the first domesticated dogs. As the authors point out, the theory makes sense not just ecologically but also geographically: the earliest Paleolithic dog discoveries primarily come from areas that were very cold at the time.

A new study provides early evidence that a Covid-19 vaccine might be effective against two new coronavirus strains first identified in South Africa and the UK, despite a concerning mutation. CNN reports: The two strains share a mutation known as N501Y that scientists worry could allow the virus to evade the immune protection generated by a vaccine. In research posted online Thursday, scientists found that antibodies from people who had received the Pfizer/BioNTech vaccine showed "no reduction in neutralization activity" against a version of the virus that carries the N501Y mutation, which they created in the lab. In order to do this, researchers tested the virus against blood from 20 people who had received two doses of the vaccine as part of a clinical trial.

The N501Y mutation is located in the coronavirus' spike protein -- the same structure targeted by vaccines. The virus uses this protein to enter the cells it attacks. This particular mutation appears to help the virus attach to human cells, which may partly explain why these new strains appear to be more transmissible. But it is just one of many mutations in both strains that scientists have worried could make the virus less susceptible to vaccines or treatments. The study -- conducted by researchers at Pfizer and the University of Texas Medical Branch -- does not test the full array of these mutation, nor has it been peer-reviewed.

An anonymous reader quotes a report from New Atlas: One of the most remarkable "sixth" senses in the animal kingdom is magnetoreception -- the ability to detect magnetic fields -- but exactly how it works remains a mystery. Now, researchers in Japan may have found a crucial piece of the puzzle, making the first observations of live, unaltered cells responding to magnetic fields. Many animals are known to navigate by sensing the Earth's magnetic field, including birds, bats, eels, whales and, according to some studies, perhaps even humans. However, the exact mechanism at play in vertebrates isn't well understood. One hypothesis suggests it's the result of a symbiotic relationship between the animals and magnetic field-sensing bacteria. But the leading hypothesis involves chemical reactions induced in cells through what's called the radical pair mechanism.

Essentially, if certain molecules are excited by light, electrons can jump between them to their neighbors. That can create pairs of molecules with a single electron each, known as a radical pair. If the electrons in those molecules have matching spin states, they will undergo chemical reactions slowly, and if they're opposites the reactions occur faster. Since magnetic fields can influence electron spin states, they could induce chemical reactions that change an animals' behavior. In the living cells of animals with magnetoreception, proteins called cryptochromes are thought to be the molecules that undergo this radical pair mechanism. And now, researchers at the University of Tokyo have observed cryptochromes responding to magnetic fields for the first time. The research was published in the journal Proceedings of the National Academy of Sciences.

The 28 fastest days on record (since 1960) all occurred in 2020, with Earth completing its revolutions around its axis milliseconds quicker than average. Live Science reports: That's not particularly alarming -- the planet's rotation varies slightly all the time, driven by variations in atmospheric pressure, winds, ocean currents and the movement of the core. But it is inconvenient for international timekeepers, who use ultra-accurate atomic clocks to meter out the Coordinated Universal Time (UTC) by which everyone sets their clocks. When astronomical time, set by the time it takes the Earth to make one full rotation, deviates from UTC by more than 0.4 seconds, UTC gets an adjustment.

Until now, these adjustments have consisted of adding a "leap second" to the year at the end of June or December, bringing astronomical time and atomic time back in line. These leap seconds were tacked on because the overall trend of Earth's rotation has been slowing since accurate satellite measurement began in the late 1960s and early 1970s. Since 1972, scientists have added leap seconds about every year-and-a-half, on average, according to the National Institute of Standards and Technology (NIST). The last addition came in 2016, when on New Year's Eve at 23 hours, 59 minutes and 59 seconds, an extra "leap second" was added.

However, according to Time and Date, the recent acceleration in Earth's spin has scientists talking for the first time about a negative leap second. Instead of adding a second, they might need to subtract one. That's because the average length of a day is 86,400 seconds, but an astronomical day in 2021 will clock in 0.05 milliseconds shorter, on average. Over the course of the year, that will add up to a 19 millisecond lag in atomic time.

An anonymous reader quotes a report from New Atlas: Mundane as it may seem, glass is a surprisingly mysterious material. Now scientists at the University of Konstanz have identified a new state of matter called liquid glass, which has some unusual properties. [...] In the new study, the researchers discovered a form of glass where the atoms exhibit a complex behavior that's never been seen in bulk glass before. Essentially, the atoms can move but aren't able to rotate. The team made this discovery in a model system of colloidal suspensions. These mixtures are made up of large solid particles suspended in a fluid, making it easier for scientists to observe the physical behavior of atoms or molecules. Normally these particles are spheres, but for this experiment the team used elliptical ones so they could tell which direction they were pointing.

The researchers tested different concentrations of particles in the fluid, tracking how well they could move and rotate. Eventually they found that at higher concentrations, the particles blocked each other from rotating, but they could still move, forming a liquid glass state. "At certain particle densities orientational motion froze whereas translational motion persisted, resulting in glassy states where the particles clustered to form local structures with similar orientation," says Andreas Zumbusch, lead author of the study. The team says that the observed behavior comes from two competing glass transitions interacting with each other. Liquid glass has been predicted for decades, and the new observation suggests that similar processes could be at work in other glass-forming systems. The research was published in the journal Proceedings of the National Academy of Sciences.

Every day in the United States, 17 people die waiting for a lifesaving organ transplant. To address this crisis, one biotech company is turning to an unlikely source: pigs. Maryland-based United Therapeutics says it plans to begin transplanting organs from genetically modified pigs into people as soon as this year. From a report: "We're right on that cusp. We're looking to get into humans within the next year or two," said David Ayares, PhD, in an exclusive interview with Future Human. Ayares is the chief scientific officer of Revivicor, a subsidiary of United Therapeutics that's developing the pigs. "We think we have the pig that is going to be what we bring forward into humans in 2021 or 2022." For decades, scientists have been hopeful that organs from other species could be used to replace faulty ones in humans, known as xenotransplantation. But animal organs trigger immediate and severe immune reactions when transplanted into humans.

The Environmental Protection Agency has finalized a rule that limits scientific research used in the crafting of public health and environmental policy. From a report: Researchers argue the rule that prioritizes studies with all data available publicly "essentially blocks" research that uses personal information and confidential medical records that can't be released because of privacy conditions, per the New York Times, which first reported the news Monday. A requirement to disclose raw data would have prevented past major studies from going ahead. "Such studies have served as the scientific underpinnings of some of the most important clean air and water regulations of the past half century," the Times notes. The EPA declined a request for comment, but referred Axios to an op-ed by Administrator Andrew Wheeler in the Wall Street Journal published Monday evening headlined, "Why We're Ending the EPA's Reliance on Secret Science." Wheeler is expected to officially announce the rule Tuesday. In the op-ed, Wheeler insists the rule is "not a stick for forcing scientists to choose between respecting the privacy and rights of their study participants and submitting their work for consideration."

UK scientists have expressed concern that COVID-19 vaccines being rolled out in Britain may not be able to protect against a new variant of the coronavirus that emerged in South Africa and has spread internationally. From a report: Both Britain and South Africa have detected new, more transmissible variants of the COVID-19-causing virus in recent weeks that have driven a surge in cases. British Health Secretary Matt Hancock said on Monday he was now very worried about the variant identified in South Africa. Simon Clarke, an associate professor in cellular microbiology at the University of Reading, said that while both variants had some new features in common, the one found in South Africa "has a number additional mutations ... which are concerning." He said these included more extensive alterations to a key part of the virus known as the spike protein -- which the virus uses to infect human cells -- and "may make the virus less susceptible to the immune response triggered by the vaccines." Lawrence Young, a virologist and professor of molecular oncology at Warwick University, also noted that the South African variant has "multiple spike mutations."

Whole Foods CEO John Mackey says the key to keeping people healthy in the United States is for people to eat better and live healthier lives. From a report: "I mean, honestly, we talk about health care. The best solution is not to need health care," Mackey told Freakonomics Radio host Stephen Dubner in an episode. "The best solution is to change the way people eat, the way they live, the lifestyle, and diet," Mackey says. "There's no reason why people shouldn't be healthy and have a longer health span. A bunch of drugs is not going to solve the problem." Americans are not taking as good care of their own bodies as they ought to be, Mackey says: "71% of Americans are overweight and 42.5% are obese. Clearly, we're making bad choices in the way we eat," he says. "It's not a sustainable path. And so, I'm calling it out."

Astronomers have taken a new look at the oldest light in the universe, which suggests that the universe is 13.77 billion years old -- give or take 40 million years. Phys.Org reports: The new estimate, using data gathered at the National Science Foundation's Atacama Cosmology Telescope (ACT), matches the one provided by the standard model of the universe, as well as measurements of the same light made by the European Space Agency's Planck satellite, which measured remnants of the Big Bang from 2009 to '13. The research was published in the Journal of Cosmology and Astroparticle Physics.

The lead author of "The Atacama Cosmology Telescope: A Measurement of the Cosmic Microwave Background Power Spectra at 98 and 150 GHz" is Steve Choi, NSF Astronomy and Astrophysics Postdoctoral Fellow at the Cornell Center for Astrophysics and Planetary Science, in the College of Arts and Sciences. In 2019, a research team measuring the movements of galaxies calculated that the universe is hundreds of millions of years younger than the Planck team predicted. That discrepancy suggested a new model for the universe might be needed and sparked concerns that one of the sets of measurements might be incorrect. "Now we've come up with an answer where Planck and ACT agree," said Simone Aiola, a researcher at the Flatiron Institute's Center for Computational Astrophysics and first author of one of two papers. "It speaks to the fact that these difficult measurements are reliable."

71-year-old Hugh Pickens (Slashdot reader #49,171) is a physicist who explored for oil in the Amazon jungle, commissioned microwave communications systems in Saudi Arabia, and built satellite control stations for Goddard Space Flight Center around the world including Australia, Antarctica, and Guam.

After retiring in 1999, he wrote over 1,400 Slashdot posts, and in the site's 23-year history still remains one of its two all-time most active submitters (behind only long-time Slashdot reader theodp). Today theodp shares an article by Hugh Pickens: I am a Covid Survivor," writes former Slashdot contributor extraordinaire Hugh Pickens (aka pickens, aka Hugh Pickens writes, aka Hugh Pickens DOT Com, aka HughPickens.com, aka pcol, aka ...). "I got the Covid six weeks ago and yesterday I was declared virus free. I had what was called a moderate case of Covid. I was never hospitalized. I was never in any real danger of death. But I was in bed for three weeks.

"It knocked me on my ass. I have been talking about my Covid when I go out and a lot of people are interested in what it really means to have a moderate case of Covid. I don't claim to speak for every Covid patient. I certainly can't speak for the ones who went into the hospital and are on ventilators. But I think the majority of people have a moderate case of Covid so I thought I would write this up for people that were interested."
During those three consecutive weeks in bed, "I guess I ate Jell-O for about two weeks..." Pickens writes. "I was laying in bed all day long. I was sleeping 12 to 14 hours a day..." He lost 25 pounds — and vividly describes having nightmares "every night like clockwork." But the essay ends with him committed to making the most of his second chance. "I'm only going to do what's important from now on...

"I'm 71 years old and I may have five more years or ten but I am going to live every day like it's my last."

"An enormous black hole keeps slipping through astronomers' nets..." reports Space.com: The big galaxy at the core of the cluster Abell 2261, which lies about 2.7 billion light-years from Earth, should have an even larger central black hole — a light-gobbling monster that weighs as much as 3 billion to 100 billion suns, astronomers estimate from the galaxy's mass. But the exotic object has evaded detection so far. For instance, researchers previously looked for X-rays streaming from the galaxy's center, using data gathered by NASA's Chandra X-ray Observatory in 1999 and 2004. X-rays are a potential black-hole signature: As material falls into a black hole's maw, it accelerates and heats up tremendously, emitting lots of high-energy X-ray light. But that hunt turned up nothing.

Now, a new study has conducted an even deeper search for X-rays in the same galaxy, using Chandra observations from 2018... But the Chandra data didn't reveal any significant X-ray sources, either in the galactic core or in big clumps of stars farther afield. So the mystery of the missing supermassive black hole persists.

That mystery could be solved by Hubble's successor — NASA's big, powerful James Webb Space Telescope, which is scheduled to launch in October 2021. If James Webb doesn't spot a black hole in the galaxy's heart or in one of its bigger stellar clumps, "then the best explanation is that the black hole has recoiled well out of the center of the galaxy," NASA officials wrote.

"Axiom Space has announced that it is creating an office park and manufacturing center at the Houston SpacePort at Ellington Field," notes an opinion piece for The Hill by Houston-based space writer Mark R. Whittington.

"The development is a hopeful sign that, despite foot dragging by Congress, a commercial replacement for the International Space Station may well happen." The United States has a chance to avoid a "space gap" when the ISS reaches the end of its operational life, like the one that happened between the end of the space shuttle program and the first launch of the SpaceX commercial crew Dragon mission. When Jim Bridenstine became NASA administrator, one of the questions confronting him was what to do about maintaining a presence in low Earth orbit after the ISS. The idea that he and experts at NASA have been pushing is to encourage private companies to build their own space station.

NASA would provide needed support by pledging to become an anchor tenant for such orbiting facilities. However, the commercial space stations would also have to find private customers. The problem is that Congress has been remarkably stingy when it comes to putting up real money for this approach. The fiscal 2020 budget request included $150 million for commercial space stations. Congress funded support for private orbiting labs for a grand total of $15 million...

Axiom Space has won the nod to attach one of its own modules to the ISS. Not waiting for Congress to cough up funding for NASA, Axiom has announced a facility to manufacture space station modules at the Ellington SpacePort in Houston. The company will also have private astronaut training facilities. Besides employing 1,000 people, the new Axiom facility represents a commitment to creating a commercial space station industry... It is also likely no accident that the Axiom facility is about a five-hour drive from the growing SpaceX spaceport in Boca Chica near the southern tip of Texas. No doubt SpaceX CEO Elon Musk would be pleased to launch finished modules to space, using the mighty Starship rocket, and later crews and cargo.

In the midst of a pandemic, part of a space future is taking shape in South Texas. This time it's being driven by the private sector. NASA had best jump on board or risk being left behind.

"When you do computer programming, what sort of mental work are you doing?" asks science/tech journalist Clive Thompson: For a long time, folks have speculated on this. Since coding involves pondering hierarchies of symbols, maybe the mental work is kinda like writing or reading? Others have speculated it's more similar to the way our brains process math and puzzles. A group of MIT neuroscientists recently did fMRI brain-scans of young adults while they were solving a small coding challenge using a textual programming language (Python) and a visual one (Scratch Jr.). The results?

The brain activity wasn't similar to when we process language. Instead, coding seems to activate the "multiple demand network," which — as the scientists note in a public-relations writeup of their work — "is also recruited for complex cognitive tasks such as solving math problems or crossword puzzles."

So, coding is more like doing math than processing language?

Sorrrrrrt of ... but not exactly so. The scientists saw activity patterns that differ from those you'd see during math, too.

The upshot: Coding — in this (very preliminary!) work, anyway — looks to be a little different from either language or math. As the note, in a media release...

"Understanding computer code seems to be its own thing...."

Just anecdotally — having interviewed hundreds of coders and computer scientists for my book CODERS — I've met amazing programmers and computer scientists with all manner of intellectual makeups. There were math-heads, and there were people who practically counted on their fingers. There were programmers obsessed with — and eloquent in — language, and ones gently baffled by written and spoken communication. Lots of musicians, lots of folks who slid in via a love of art and visual design, then whose brains just seized excitedly on the mouthfeel of algorithms.

Since 1976 "Project Censored," a U.S.-based nonprofit media watchdog organization, has been identifying "the news that didn't make the news," the most significant stories it believes are being systematically overlooked. Slashdot ran stories about its annual list of the year's most censored news stories in 1999, 2003, 2004, and in 2007, when they'd presciently warned that the media was ignoring the issue of net neutrality.

But their latest list of underreported stories includes this disturbing headline: "Antibiotic Abuse: Pharmaceutical Profiteering Accelerates Superbugs." Pharmaceutical giants Abbott and Sun Pharma are providing dangerous amounts of antibiotics to unlicensed doctors in India and incentivizing them to overprescribe. In August 2019 the Bureau of Investigative Journalism (BIJ) reported that these unethical business practices are leading to a rise in superbugs, or bacterial infections that are resistant to antibiotic treatment. Bacteria naturally evolve a resistance to antibiotics over time, but the widespread and inappropriate use of antibiotics accelerates this process. Superbugs are killing at least 58,000 babies each year and rendering a growing number of patients untreatable with all available drugs.

India's unlicensed medical practitioners, known as "quack" doctors, are being courted by Abbott and Sun Pharma, billion-dollar companies that do business in more than one hundred countries, including the United States. The incentives these companies provide to quack doctors to sell antibiotics have included free medical equipment, gift cards, televisions, travel, and cash, earning some doctors nearly a quarter of their salary. "Sales representatives would also offer extra pills or money as an incentive to buy more antibiotics, encouraging potentially dangerous overprescription," a Sun Pharma sales representative revealed to an undercover BIJ reporter... [P]atients without access to better care often turn to quack doctors for treatment, and many are unaware that their local medical "professionals" have no formal training and are being bribed to sell unnecessary antibiotics.

In September 2019, the BIJ reported on similar problems with broken healthcare systems, medical corruption, and dangerous superbugs in Cambodia. Their account describes how patients often request antibiotics for common colds, to pour onto wounds, and to feed to animals. Illegally practicing doctors and pharmacists in Cambodia admitted that they would often prescribe based on customer requests rather than appropriate medical guidelines. As the BIJ noted, "This kind of misuse speeds up the creation of drug resistant bacteria, or superbugs, which are predicted to kill 10 million people by 2050 if no action is taken...."

Although superbugs have attracted some attention, their cause and importance remain poorly understood by the public. The Independent and BuzzFlash republished the Bureau of Investigative Journalism's report; otherwise, the role of pharmaceutical companies in the rise of dangerous superbugs has been drastically underreported.
The site's list of the top 25 censored stories of 2019 - 2020 also includes:

• Growing interest in so-called "public" banks, "not legally obligated to maximize profits, as private banks are; instead, public banks are mandated to serve their communities."

• How rising sea levels and warmer waters will impact nuclear power plants, "posing increased risks of nuclear disasters."

• Proposals to revitalize journalism through public funding.

• How the U.S. military represents "a massive, hidden contributor to the climate crisis."

Writing in Time magazine, two neuroscientists share a surprising new theory on exactly how dreaming protects our brains: Neuroscience used to think that different parts of the brain were predetermined to perform specific functions. But more recent discoveries have upended the old paradigm. One part of the brain may initially be assigned a specific task; for instance, the back of our brain is called the "visual cortex" because it usually handles sight. But that territory can be reassigned to a different task... Recent decades have yielded several revelations about livewiring, but perhaps the biggest surprise is its rapidity...

In the ceaseless competition for brain territory, the visual system has a unique problem: due to the planet's rotation, all animals are cast into darkness for an average of 12 out of every 24 hours... So how did the visual cortex of our ancestors' brains defend its territory, in the absence of input from the eyes? We suggest that the brain preserves the territory of the visual cortex by keeping it active at night. In our "defensive activation theory," dream sleep exists to keep neurons in the visual cortex active, thereby combating a takeover by the neighboring senses. In this view, dreams are primarily visual precisely because this is the only sense that is disadvantaged by darkness. Thus, only the visual cortex is vulnerable in a way that warrants internally-generated activity to preserve its territory...

REM sleep is triggered by a specialized set of neurons that pump activity straight into the brain's visual cortex, causing us to experience vision even though our eyes are closed... The anatomical precision of these circuits suggests that dream sleep is biologically important — such precise and universal circuitry rarely evolves without an important function behind it... We suggest that dream sleep exists, at least in part, to prevent the other senses from taking over the brain's visual cortex when it goes unused. Dreams are the counterbalance against too much flexibility.

Thus, although dreams have long been the subject of song and story, they may be better understood as the strange lovechild of brain plasticity and the rotation of the planet.
