Tardigrades, also known as water bears, are a diverse group of charismatic microscopic invertebrates that are best known for their ability to survive extreme conditions. A famous example was a 2007 trip to space where tardigrades were exposed to the space vacuum and harmful ionizing solar radiation, and still managed to survive and reproduce after returning to Earth. Tardigrades are found in all t

Frances Haugen, a former product manager at the company, says she came forward after she saw Facebook's leadership repeatedly prioritize profit over safety. Before quitting in May of this year, she comb
The Colorado healthcare system UCHealth is under fire for a new policy in which it will only give organ transplants to patients who have been vaccinated against COVID-19. Colorado State Representative Tim Geitner criticized the new rules when he said that an unvaccinated woman reached out to him after being told she would be denied a kidney transplant unless she got vaccinated within 30 days, The
Scientists at Stanford University have discovered a surprising pattern in how life reemerges from cataclysm. Research published Oct. 6 in Proceedings of the Royal Society B shows the usual rules of body size evolution change not only during mass extinction, but also during subsequent recovery.
Research published in the SIAM Journal on Applied Mathematics describes a new mathematical model for studying influence across social networks. Using tools from the field of topology, Robert Ghrist and Ph.D. graduate Jakob Hansen developed a framework to track how opinions change over time in a wide range of scenarios, including ones where individuals can use deceptive behaviors and propaganda age
Exoplanet hunters have found thousands of planets, most orbiting close to their host stars, but relatively few alien worlds have been detected that float freely through the galaxy as so-called rogue planets, not bound to any star. Many astronomers believe that these planets are more common than we know, but that our planet-finding techniques haven't been up to the task of locating them.
By decoding honeybees' waggle dances, which tell other bees where to find food, researchers have found that bees in agricultural areas travel further for food than those in urban areas. The findings are published in the British Ecological Society's Journal of Applied Ecology.
Farming should be as high-yield as possible so it can be limited to relatively small areas, allowing much more land to be left as natural habitats while still meeting future food targets, according to a major new analysis of over a decade of research.
To prevent the spread of COVID-19 indoors, the two meters physical distancing guideline is not enough without masks, according to researchers. However, wearing a mask indoors can reduce the contamination range of airborne particles by about 67 percent.
They've famously survived the vacuum of space, and even returned to life after being frozen for decades in Antarctic moss. But as hard as it is to kill the bizarre microscopic animal, the tardigrade, it's harder to find one fossilized. In fact, only two have ever been discovered and formally named — until now.
Raining Drones In an eerie bit of imagery, drones literally started raining from the sky in Zhengzhou, a city of 10 million people in the Chinese province of Henan. Videos shared on social media show a constellation of drones starting to quickly lose altitude before clattering down on the ground. Onlookers can be seen jumping out of the way to avoid getting struck by the small drones. The inciden
Pendraig milnerae was related to T rex and likely to have been apex predator despite its size, say experts A dinosaur distantly related to Tyrannosaurus rex – but with a body the size of a chicken – that would probably have ruled the roost about 200m years ago has been discovered. The diminutive but fearsome creature, whose fossilised remains were found in a quarry in south Wales, is the oldest t

What if managers and leaders at companies focused on a new goal: to elevate the human experience? This paradigm shift is something Amelia Dunlop, chief experience officer at Deloitte Digital, advocates for. She and her team have worked hard to measure the amount of humanity in the workplace—a measurement that often depends on how much trust exists between workers and leaders. Dunlop's team focuse
Cooling impact of very explosive eruptions could be amplified while moderate eruptions have less effect It's well known that volcanic eruptions alter the climate but can human-made climate change alter volcanic eruptions? Curiously, the answer appears to be yes. When the Philippine volcano Mount Pinatubo erupted in 1991, the resulting sulphuric acid haze suppressed global temperatures by 0.5C for

Chemists are constantly tasked not just with designing useful new molecules — ones for novel drugs, energy-storing materials and countless other jobs — but with designing better ways to make those molecules. One big hurdle is that desirable chemical reactions are often slow or inefficient, and can only become practical with the addition of catalysts, substances that can accelerate reaction rates.
Family groups for congenital Zika syndrome have sprung up across Brazil, and members are increasingly at odds with the scientists who have used their children for research. Some scientists recognize the problem, yet others are unsure of how to deal with the families' distrust.
This year's Nobel prize in physics has been split between Syukuro Manabe, Klaus Hasselmann and Giorgio Parisi. While Parisi is a theoretical physicist, the other two are climate modellers whose work laid the foundations of our understanding of how carbon dioxide would shape the climate.

We announce the creation of a new body within the National Academies of Sciences, Engineering, and Medicine called the Strategic Council for Research Excellence, Integrity, and Trust, charged with advancing the overall health, quality, and effectiveness of the research enterprise across all domains that fund, execute, disseminate, and apply scientific…
When bestselling science-fiction writer Kim Stanley Robinson opened his latest novel, The Ministry for the Future, he set the scene in India, where a deadly heat dome wipes out almost the entire population of a provincial city, sowing the seed for a radical political movement to combat climate change.
Considered an ultra-hot Jupiter — a place where iron gets vaporized, condenses on the night side and then falls from the sky like rain — the fiery, inferno-like WASP-76b exoplanet may be even more sizzling than scientists had realized.
Researchers have made a surprising discovery about the human gut's enteric nervous system that itself is filled with surprising facts. For starters, the fact that this "second brain" exists at all. "Most people don't even know that they have this in their guts," says Brian Gulbransen, professor in the College of Natural Science's physiology department at Michigan State University. Beyond that, th
A huge slick of oil stalked the California coast Tuesday as officials frantically tried to protect ecologically sensitive shorelines and investigators probed whether a ship's anchor caused a pipe breach that sent tens of thousands of gallons of crude into the waters off Orange County.
A "flash Joule" process to extract valuable metals from electronic waste would use up to 500 times less energy than current lab methods and produce a byproduct clean enough for agricultural land. Researchers have adapted the flash Joule heating method introduced last year to produce graphene from carbon sources like waste food and plastic to recover rhodium, palladium, gold, and silver for reuse.
Sense of smell or taste returns within six months for 4 out of every 5 COVID-19 survivors who have lost these senses, and those under 40 are more likely to recover these senses than older adults, an ongoing study found.
New research looks at ways to incentivize almond growers to adopt bee-friendly practices, such as planting cover crops, adopting permanent pollinator habitat, and adopting best management practices for bees. Almonds are big business in California, which grows 80% of the world's crop with a value of $5.62 billion. To get those almonds to grow, farmers need bees to pollinate their crop. And bee pop
