Imagine, if you will, that future humans manage to travel to other worlds and find… more humans. According to one University of Cambridge astrobiologist, that scenario may be more likely than you'd think. In a new interview with the BBC 's Science Focus magazine , an evolutionary palaeobiologist at the institution's Department of Earth Sciences named Simon Conway Morris declared that researchers

Any long term human presence on Mars — colonization, research, visit and travel — that didn't confine settlers to airtight compounds would rely on a stable atmosphere that doesn't lose too many particles or fry human bodies with too much radiation. Now, scientists from a star-studded list of universities and organizations, including NASA's own chief scientist James Lauer Green, are suggesting tha
T he change started about a year ago. I had just finished cooking my Thanksgiving turkey. I'd picked up smoking meats as a hobby during the first year of the pandemic, but that day, I couldn't really taste much. Later that night, I wasn't able to smell anything. Soon I was quarantined in a room in our house. For 11 days my wonderful, patient wife would bring bottles of Pedialyte to my door. I was

Feel the Love The United Kingdom has confirmed what everybody who ugly cried during "My Octopus Teacher" already knew: Octopuses are sentient — capable, that is, of perceiving things like pain and pleasure. The country is adding an amendment to its Animal Welfare Sentience Bill to recognize creatures such as octopus, crabs, squids, and lobsters along with "all other decapod crustaceans and cephal
Programme to allow those with prestigious global prizes to get fast-track visas dismissed as 'elitist' and a 'joke' A post-Brexit scheme to draw the world's most celebrated academics and other leading figures to the UK has failed to attract a single applicant in the six months since it opened, it has been reported. The visa route open to Nobel laureates and other prestigious global prize winners
Ring of hollows has been called the largest prehistoric structure found in Britain, but some were sceptical When a series of deep pits were discovered near the world heritage site of Stonehenge last year, archaeologists excitedly described it as the largest prehistoric structure ever found in Britain – only for some colleagues to dismiss the pits as mere natural features. Now scientific tests hav
Bank Memes Last week JPMorgan sued Tesla , arguing the company owed it $162 million. "We have provided Tesla multiple opportunities to fulfill its contractual obligations, so it is unfortunate that they have forced this issue into litigation," read a statement issued by the bank. And now, Musk is beefing with the bank — in the most Musk way imaginable. "If JPM doesn't withdraw their lawsuit, I wi
A new book tells the story of the painstaking process to preserve the 1,200-year-old Faddan More Psalter One summer's day in Tipperary as peat was being dug from a bog, a button peered out from the freshly cut earth. The find set off a five-year journey of conservation to retrieve and preserve what lay beyond: a 1,200-year-old psalm book in its original cover. Bogs across Europe have thrown up al
Test drive of planetary defence system aims to provide data on how to deflect asteroids away from Earth That's one large rock, one momentous shift in our relationship with space. On Wednesday, Nasa will launch a mission to deliberately slam a spacecraft into an asteroid to try to alter its orbit – the first time humanity has tried to interfere in the gravitational dance of the solar system.

Are we alone in the universe? It comes down to whether intelligence is a probable outcome of natural selection, or an improbable fluke . By definition, probable events occur frequently, improbable events occur rarely—or once. Our evolutionary history shows that many key adaptations—not just intelligence, but complex animals, complex cells, photosynthesis, and life itself—were unique, one-off even
A University of Alaska Fairbanks scientist has discovered a method for detecting and better defining meteorite impact sites that have long lost their telltale craters. The discovery could further the study of not only Earth's geology but also that of other bodies in our solar system.
Just about everyone knows that exercise is good for you. Some people can even rattle off reasons it keeps your muscles and joints strong, and how it fights off certain diseases. But how many people can tell you the story of why and how physical activity was built into human biology?
An international team of astronomers reports the detection of a black hole in a globular cluster known as NGC 1850. The newly found black hole is about 11 times more massive than the sun and turns out to be a part of a binary system. The finding was detailed in a paper published November 12 on arXiv.org.
After studying the effectiveness of varying layers of masks in stopping respiratory droplets from escaping face masks, a team of international researchers has now turned their attention to modeling what happens to droplets when they come in contact with wet masks. Their results show that damp masks are still effective at stopping these droplets from escaping the mask and being atomized into smalle
Scientists recently added a whopping 301 newly validated exoplanets to the total exoplanet tally. The throng of planets is the latest to join the 4,569 already validated planets orbiting a multitude of distant stars. How did scientists discover such a huge number of planets, seemingly all at once? The answer lies with a new deep neural network called ExoMiner.
Researchers from the University of Cambridge have used a suite of correlative, multimodal microscopy methods to visualize, for the first time, why perovskite materials are seemingly so tolerant of defects in their structure. Their findings were published today in Nature Nanotechnology.
Fast radio bursts (FRBs) are bright pulses of emission at radio wavelengths (seen mostly at wavelengths of tens of centimeters) whose physical mechanism(s) are mysterious. The bursts last between hundredths of a millisecond to a few milliseconds, and none of them has been associated with a specific source, even though thousands of FRBs have been detected since the first one was spotted fourteen ye
Quantum dots, discovered in the 1990s, have a wide range of applications and are perhaps best known for producing vivid colors in some high-end televisions. But for some potential uses, such as tracking biochemical pathways of a drug as it interacts with living cells, progress has been hampered by one seemingly uncontrollable characteristic: a tendency to blink off at random intervals. That doesn'
In the strange, dark world of the ocean floor, underwater fissures, called hydrothermal vents, host complex communities of life. These vents belch scorching hot fluids into extremely cold seawater, creating the chemical forces necessary for the small organisms that inhabit this extreme environment to live.
A new study has shown that the airborne transmission of COVID-19 is highly random and suggests that the two-meter rule was a number chosen from a risk 'continuum', rather than any concrete measurement of safety.
Scientists have discovered a new process to break bulk metal into atoms to produce heterogeneous catalysts without any chemical waste, which will lead to new sustainable ways of making and using molecules in the most atom-efficient way.
By disrupting normal societal activities, such as driving, COVID-19 lockdowns afforded a unique opportunity to study their impacts on the environment. Researchers now report in ACS' Environmental Science & Technology Letters that satellite data from before and during the spring 2020 lockdown in Los Angeles shows that vehicles, rather than agriculture, are the main source of urban airborne ammonia
A new study from The Australian National University (ANU) has revealed the death rate of babies in ancient societies is not a reflection of poor healthcare, disease and other factors, but instead is an indication of the number of babies born in that era.
The launch of the James Webb Space Telescope, which astronomers hope will herald a new era of discovery, has been delayed until December 22 after an accident at its launch facility in French Guiana, NASA said Monday.
Many studies in psychology have shown that people judge how trustworthy a person is on the basis of their first impression of the other person's facial features. Whether there actually are differences between men and women in this respect has now been investigated by the researchers Dr. Johanna Brustkern, Prof. Dr. Markus Heinrichs and Dr. Bastian Schiller from the Department of Psychology at the
A pair of researchers at the University of California, Davis has found that the neonicotinoid pesticide imidacloprid can reduce fertility rates in the blue orchard bee. In their paper published in Proceedings of the National Academy of Sciences, the group describes testing the response of the valuable pollinator to the presence of imidacloprid.
Researchers and sleep experts are ringing alarm bells about a nascent marketing tactic: injecting advertisements into your dreams.

Potty Humor In an extremely shocking turn of events, Tesla and SpaceX CEO Elon Musk has claimed that he posts "at least" half of his tweets from the toilet. "At least 50% of my tweets were made on a porcelain throne," Musk tweeted Sunday night , presumably from the toilet. "It gives me solace," he added . On a basic level, this isn't that shocking, because really, who among us can claim they don'
Thomas Gehrmann remembers the deluge of mathematical expressions that came cascading down his computer screen one day 20 years ago. He was trying to calculate the odds that three jets of elementary particles would erupt from two particles smashing together. It was the type of bread-and-butter calculation physicists often do to check whether their theories match the results of experiments. Source
If you thought polarization was bad during the last two elections, get ready for the next iteration of Facebook and Mark Zuckerberg's power over reality.

"Folks should be worried," AR entrepreneur Shawn Frayne told Insider
Watching Saturday Night Live has always been an uneven experience—there are duds and gems, silliness and darker satire, and often stark shifts in tone from one sketch to the next. But given the anxious state of the world today, watching the show has started to feel uncannily like doomscrolling through a social-media feed. The news the show is riffing on has been unrelentingly bleak for years, and
Opportunities for business, health and the environment offered by superfast processors are huge – and so are the hurdles The technology behind everyday computers such as smartphones and laptops has revolutionised modern life, to the extent that our day-to-day lives are unimaginable without it.

S ocial media gets blamed for many of America's ills, including the polarization of our politics and the erosion of truth itself. But proving that harms have occurred to all of society is hard. Far easier to show is the damage to a specific class of people: adolescent girls, whose rates of depression, anxiety, and self-injury surged in the early 2010s, as social-media platforms proliferated and e
One of the things that astronauts need to contend with when we colonize Mars is isolation. After all, they'll be alone with just their fellow crew members for months or even years at a time. Plus, it could get even get worse if a "The Martian" situation occurs and someone ends up totally alone on the Red Planet. Unfortunately, a recent long term isolation experiment on a simulated Mars base found
Unplanned Release After decades of delays and billions of dollar spent, NASA's James Webb Space Telescope is encountering even more hiccups ahead of its launch — and this time, it appears to be plain old human error. This time, technicians encountered a heart-stopping "incident" while mounting the structure to the Ariane 5 rocket's launch vehicle adapter. "A sudden, unplanned release of a clamp b
Less than a year ago, America was led by a man who governed to please the Fox News host Tucker Carlson and toyed with the idea of imposing martial law . After Donald Trump, you'd think the American people would just enjoy having a normal president who doesn't use his Twitter account to threaten neighboring countries or corporations . But they don't. Take one look at national polling numbers and y
Bitcoin City El Salvador's president Nayib Bukele has announced plans to build the world's first fully crypto-backed "Bitcoin City." Bukele made the announcement over the weekend as part of a cringe-inducing live show featuring bright concert-style lighting — and even tacky CGI UFOs , for some reason. He says Bitcoin City will be income, property, and capital gains tax free, and be funded by El S
No one broke Adele's heart this time. Until now, her music has centered on the brutality of romantic rejection—the way it can throw a human soul against a wall, snapping bones that never heal right, instilling a kind of existential PTSD. Yet, though her new album is about " divorce, babe, divorce ," betrayal, cruelty, and nasty rumors are for once not part of the story. According to Adele's inter
Chief Email Officer According to an email sent to all staff at Tesla in early October and obtained by CNBC , CEO Elon Musk warned that any manager who doesn't execute his directions, state why they believe he is wrong, or request further clarification, will be "asked to resign immediately." It's a decisive tone that shouldn't come as too much of a shock — Musk is the CEO, after all. And, to be fa

The setting was grand: the French Senate, a chamber as elegant as an opera ho
If Donald Trump tries to run for president again, one of his former campaign advisers has a plan to dissuade him. Anticipating that Trump may not know who Adlai Stevenson was or that he lost two straight presidential elections in the 1950s, this ex-adviser figures he or someone else might need to explain the man's unhappy fate. They'll remind Trump that if he were beaten in 2024, he would join St

He's a law student who wan
Artificial neural networks are famously inspired by their biological counterparts. Yet compared to human brains, these algorithms are highly simplified, even "cartoonish." Can they teach us anything about how the brain works? For a panel at the Society for Neuroscience annual meeting this month, the answer is yes. Deep learning wasn't meant to model the brain. In fact, it contains elements that a

They burst into the home, eventually finding the movie star wearing a bathrobe in his kitchen. Gibson put his hands up and the agents cuffed him immediately, over protestations that he had done nothing wrong, and certainly nothing dangerous. His crime? The posses
It's a tempting thought: With climate change so difficult to manage and nations unwilling to take decisive action, what if we could mitigate its effects by setting up a kind of chemical umbrella—a layer of sulfuric acid in the upper atmosphere that could reflect the sun's radiation and cool the Earth?
If you brush against the wings of a butterfly, you will likely come away with a fine sprinkling of powder. This lepidopteran dust is made up of tiny microscopic scales, hundreds of thousands of which paper a butterfly's wings like shingles on a wafer-thin roof. The structure and arrangement of these scales give a butterfly its color and shimmer, and help shield the insect from the elements.
Children as young as age 6 develop ideas that girls are less interested than boys in computer science and engineering—stereotypes that can extend into the late teens and contribute to a gender gap in STEM college courses and related careers.
Hackers around the globe are smart: they know that it isn't just good code that helps them break into systems; it's also about understanding—and preying upon—human behavior.

Progress in quantum computing is no longer just about how big your chip is. But IBM has taken a major leap forward with the release of a 127-qubit processor. Milestones in quantum computing are getting increasingly difficult to asses as the variety of technologies and the yardsticks used to judge them proliferate. While both IBM and Google build their devices out of superconducting qubits, differ
Since the discovery of quasicrystals (QCs), solids that mimic crystals in their long-range order but lack periodicity, scientists have sought physical properties related to their peculiar structure. Now, an international group of researchers led by Tokyo University of Science, have reported a long-range magnetic order in QCs with icosahedral symmetry that turns ferromagnetism below certain tempera
Tiny amounts of heat can be used to control the movement of magnetic whirlpools called skyrmions, RIKEN physicists have shown. This ability could help to develop energy-efficient forms of computing that harness waste heat.
Terraforming Mars is one of the great dreams of humanity. Mars has a lot going for it. Its day is about the same length as Earth's, it has plenty of frozen water just under its surface, and it likely could be given a reasonably breathable atmosphere in time. But one of the things it lacks is a strong magnetic field. So if we want to make Mars a second Earth, we'll have to give it an artificial one

The separate, previously unknown, missile release reportedly took place while the vehicle was soaring at hypersonic speeds China's launch of a nuclear-capable missile carrying a hypersonic glide vehicle also included the unprecedented launch of a separate missile from that vehicle, according to multiple reports. The test showed China's development of its strategic, nuclear-capable weapons as more
The hunt for planets beyond our solar system has turned up more than 4,000 far-flung worlds, orbiting stars thousands of light years from Earth. These extrasolar planets are a veritable menagerie, from rocky super-Earths and miniature Neptunes to colossal gas giants.
It's been 70 years since physicist Enrico Fermi asked his famous question: "Where is everybody?" And yet, the tyranny of the Fermi Paradox is still with us and will continue to be until definitive evidence of extraterrestrial intelligence (ETI) is found. In the meantime, scientists are forced to speculate as to why we haven't found any yet and, more importantly, what we should be looking for. By f

Scientific journals are expected to consider research manuscripts dispassionately and without favor. But in a study publishing on November 23rd in the open access journal PLOS Biology, Alexandre Scanff, Florian Naudet and Clara Locher from the University of Rennes, and colleagues, reveal that a subset of journals may be exercising considerable bias and favoritism.
Matthew Heineman's powerful documentary captures the most acute weeks of the crisis as a Long Island hospital struggles to cope Shot inside a New York hospital at the start of the pandemic, this documentary is an overwhelming emotional watch. In March last year, City of Ghosts director Matthew Heineman started filming on the wards of the Long Island Jewish Medical Center ; he stayed for four mont
No one remembers when you're right, but no one forgets when you're wrong. Your local weather person knows that saying all too well. But while they take a lot of the heat (get it?), how much of it is actually justified? In this episode, Mona Chalabi looks at weather forecasting data to see how accurate these predictions really are, and gives us tips for when we should–and shouldn't–trust the fore
How much and how long a severely burned Pacific Northwest mountain landscape stays blanketed in winter snow is a key factor in the return of vegetation, research by Oregon State University and the University of Nevada, Reno shows.
Analysis shows job adverts requiring candidates to be jabbed rose by 189% between August and October Employers in the UK are following the lead of their counterparts in the US by stepping up demands for staff to be vaccinated against Covid-19, analysis of recruitment adverts reveals. According to figures from the jobs website Adzuna, the number of ads explicitly requiring candidates to be vaccina
This may sound harsh, but Clint Barton, a.k.a. Hawkeye, was never the most exciting Avenger in the Marvel films. Next to near-invincible heroes such as Thor, Captain America, and the Hulk, he just looked ill-equipped, wielding a bow and arrow against monstrous aliens and killer robots. One of the original six protagonists in 2012's Avengers , the master archer (played by Jeremy Renner) gradually
The perception of gender in children's voices is of special interest to researchers, because voices of young boys and girls are very similar before the age of puberty. Adult male and female voices are often quite different acoustically, making gender identification fairly easy.
Artificial intelligence technology is now used by a growing number of companies looking to hire the best employees, but new research from Rice University warns how it can incorporate biases and overlook important characteristics among job applicants.
Over the past several decades, researchers have moved from using electric currents to manipulating light waves in the near-infrared range for telecommunications applications such as high-speed 5G networks, biosensors on a chip, and driverless cars. This research area, known as integrated photonics, is fast evolving and investigators are now exploring the shorter—visible—wavelength range to develop
Seismic data collected in Elysium Planitia, the second largest volcanic region on Mars, suggest the presence of a shallow sedimentary layer sandwiched between lava flows beneath the planet's surface. These findings were gained in the framework of NASA's InSight mission (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport), in which several international research partners,
The brightest star in the constellation Gemini, the twins, is named after the son of Leda and Zeus On the evening of 23 November, the moon will have a close encounter with the star Pollux, the brightest star in the constellation Gemini, the twins. Pollux marks the head of one twin. The other twin is marked by the star Castor. Although Pollux is the brighter star, it was Castor that was given the
Alberta's tar sands — also called oil sands — have helped make Canada the world's fourth-largest oil producer, with significant economic benefits. But the ecological impacts are so vast and so deep that the local Indigenous people say the industry has challenged their very existence.
The ancient arts of origami, the art of paper-folding, and kirigami, the art of paper-cutting, have gained popularity in recent years among researchers building mechanical metamaterials. Folding and cutting 2D thin-film materials transforms them into complex 3D structures and shapes with unique and programmable mechanical properties.
Coral reefs are among the most species-rich ecosystems on the planet. Octocorals, which include soft corals, gorgonians, and sea pens, are important members of these marine communities. They could even outcompete reef-building stony corals in the future, as they are better able to deal with heat stress and increasing ocean acidification, which makes them less sensitive to the consequences of globa
Rice University engineers have achieved a new benchmark in the design of atomically thin solar cells made of semiconducting perovskites, boosting their efficiency while retaining their ability to stand up to the environment.
An elegant ballet of proteins enables modern cells to replicate themselves. During cell division, structural proteins and enzymes coordinate the duplication of DNA, the division of a cell's cytoplasmic contents, and the cinching of the membrane that cleaves the cell. Getting these processes right is crucial because errors can lead to daughter cells that are abnormal or unviable. Source
Cells can produce unique electrical signals. These signals can be linked to various cancers, such as the breast, lung, liver, brain, pancreas and prostate cancers, meaning that they can be used as indicators for early cancer diagnosis. Thus, using electrical signals as indicators and targets for cancer treatments could potentially improve the outcome for cancer patients. A team of researchers from
Based on the identification of plant remains, Tel Aviv University and Tel-Hai College researchers provide the first detailed reconstruction of the climate in the Land of Israel at the end of the last ice age (20,000-10,000 years before present). The researchers claim that significant climate changes characterizing the period, manifested by sharp differences in temperature and precipitation not onl
An exhausted star still has some punches to deliver. Astronomers have found that a white dwarf is pummeling a companion object—either a lightweight star or a planet—with incessant blasts of heat and radiation plus a relentless gravitational pull tearing it apart.
In the early weeks of their lives and even before birth, babies are skilfully processing important information about the sounds they hear. They are attuning to tones, patterns of language and distinguishing their own familiar adults' voices. Making sense of sounds, patterns, words and sentences are important skills that will help a child as they progress towards reading.
A putative brain surgeon with a penchant for fabricating his affiliations and co-authors — including Wolf Blitzer of CNN — has lost several more papers to retraction. As we reported in August, Michael George Zaki Ghali, or someone using that name: bought two fake web domains for the Karolinska Institutet [KI] to make it look … Continue reading
One of the environmental legacies of COVID-19 may well be vast amounts of plastic pollution. Since the beginning of the pandemic, scientists have warned of the long-term threat of littering face masks and other PPE into the environment.
The Prawn Nebula is a massive stellar nursery located in the constellation Scorpius, about 6,000 light years from Earth. Though the nebula stretches 250 light-years and covers a space four times the size of the full moon, it emits light primarily in wavelengths the human eye cannot detect, making it extremely faint to earthbound viewers. Hubble's gaze, however, shows a small section of the nebula
Albatrosses do not fall in love the way humans do. When the birds couple up, it's almost always for keeps. Their lives start lonely—albatross parents lay only one egg at a time, and may leave their offspring unattended for days—and at just a few months old, each juvenile embarks on an epic solo voyage at sea. They fly for months and months and months, learning what it is to be a bird. "It can be
Billionaires are extremely keen on getting into space — and taking other billionaires' money in exchange for a seat. Here's how to talk to your family about it. As You Pass the Mashed Potatoes As of right now, a handful of companies are starting to sell tickets on board their spacecraft to "space," with the hopes of establishing an entirely new industry. But everything from the environmental impa
Speech sounds elicit comparable neural responses and stimulate the same region in the brain of humans, macaques and guinea pigs, researchers report. The finding could help pave the way for better understanding and diagnosis of auditory processing deficits.
'Plague sceptics' are wrong to underestimate the devastating impact that bubonic plague had in the 6th to 8th centuries CE, argues a new study based on ancient texts and recent genetic discoveries. The same study suggests that bubonic plague may have reached England before its first recorded case in the Mediterranean via a currently unknown route, possibly involving the Baltic and Scandinavia.
Previous research has found that chemotherapy can trigger muscle loss in people living with cancer, but a new study out of found it may also affect the way the body builds new muscle — and at lower doses than previously known, having potential implications for treatments and rehab programs.
Researchers have conducted an empirical field study and concluded that single urban trees, such as street trees, function differently than trees grown in clusters featuring significantly greater transpiration rates. This result offers a new understanding of how to manage the landscape in urban settings to reduce the harmful effects of stormwater runoff.
Scientists have used glowing chemicals and other techniques to create a 3D map of the blood vessels and self-renewing 'stem' cells that line and penetrate a mouse skull. The map provides precise locations of blood vessels and stem cells that scientists could eventually use to repair wounds and generate new bone and tissue in the skull.
Researchers have new evidence that could help rapidly boost efforts to scale-up the adoption of clean cooking with liquefied petroleum gas (LPG) in sub-Saharan Africa. The new study suggests that supply-side interventions such as shortening the distance to LPG retail points and improving access to multi-burner LPG stoves could help increase the consumption of the clean cooking fuels, for the benef
Safe, cheap and sustainable technology for energy storage has been developed. It is based on two major breakthroughs: the manufacture of wood-based electrodes in rolled form, and a new type of water-based electrolyte.
Immune checkpoint inhibitors strengthen the immune response against cancer cells, but the medications are ineffective against certain tumors. Results from a new clinical trial indicate that adding radiation may overcome this resistance to immune checkpoint inhibitors.

The Flame Nebula or NGC 2024 is a large star-forming region in the constellation Orion that lies about 1,400 light-years from Earth. Hubble studied this nebula to look for protoplanetary disks, or "proplyds"—disks of gas and dust around stars that may one day form new solar systems.
When a person experiences a trauma that leads to significant bleeding, the first few minutes are critical. It's important that they receive intravenous medication quickly to control the bleeding, but delivering the medication at the right rate can prove challenging. Slower infusions can cause fewer negative reactions, but the medication might not work fast enough, particularly in the case of a ser
Floods, droughts, heat waves and cold blasts — why is the weather becoming more extreme? Environmentalist and "America's weatherman" Al Roker discusses the link between climate change and disruptions to weather patterns worldwide, followed by a conversation between Nobel laureate Al Gore and TED science curator David Biello about the science of extreme weather and emerging solutions to reduce the
Investing in green energy, holding large corporations accountable for their pollution, stopping pipeline and oil extraction initiatives — these are non-negotiable actions to protect the planet, but they are still just the bare minimum, say climate activists Xiye Bastida and Shiv Soin. In conversation with radio researcher Latif Nasser, Bastida and Soin share their list of six crucial climate dema

NASA has been working on the James Webb Space Telescope for 20 years, and there have been numerous delays. The marvel of astronomical technology is currently preparing for launch, but NASA says we'll have to wait just a bit longer . Following a minor "incident," NASA has pushed the launch of Webb back by four days. That will give the team time to check for damage one last time before launch. The
The development of inherently safe energy devices is a key challenge, and aqueous Li-ion batteries draw large attention for this purpose. Due to the narrow electrochemical stable potential window of aqueous electrolytes, the energy density and the selection of negative electrode materials are significantly limited. For achieving durable and high-energy…
The mapping from protein sequence to function is highly complex, making it challenging to predict how sequence changes will affect a protein's behavior and properties. We present a supervised deep learning framework to learn the sequence–function mapping from deep mutational scanning data and make predictions for new, uncharacterized sequence variants….
Cytokinin (CK) in plants regulates both developmental processes and adaptation to environmental stresses. Arabidopsis histidine phosphotransfer ahp2,3,5 and type-B Arabidopsis response regulator arr1,10,12 triple mutants are almost completely defective in CK signaling, and the ahp2,3,5 mutant was reported to be salt tolerant. Here, we demonstrate that the arr1,10,12 mutant is…
Common fragile sites (CFSs) are difficult-to-replicate genomic regions that form gaps and breaks on metaphase chromosomes under replication stress. They are hotspots for chromosomal instability in cancer. Repetitive sequences located at CFS loci are inefficiently copied by replicative DNA polymerase (Pol) delta. However, translesion synthesis Pol eta has been shown…
We studied the brain mechanisms underlying action selection in a social dilemma setting in which individuals' effortful gains are unfairly distributed among group members. A stable "worker–parasite" relationship developed when three individually operant-conditioned rats were placed together in a Skinner box equipped with response lever and food dispenser on opposite…
In recent years, we have come to appreciate the astounding intricacies associated with the formation of minerals from ions in aqueous solutions. In this context, a number of studies have revealed that the nucleation of calcium sulfate systems occurs nonclassically, involving the aggregation and reorganization of nanosized prenucleation species. In…
Ribosomes translate RNA into proteins. The protein synthesis inhibitor cycloheximide (CHX) is widely used to inhibit eukaryotic ribosomes engaged in translation elongation. However, the lack of structural data for actively translating polyribosomes stalled by CHX leaves unanswered the question of which elongation step is inhibited. We elucidated CHX's mechanism of…
Carriers of heterozygous germline BAP1 mutations (BAP1+/−) are affected by the "BAP1 cancer syndrome." Although they can develop almost any cancer type, they are unusually susceptible to asbestos carcinogenesis and mesothelioma. Here we investigate why among all carcinogens, BAP1 mutations cooperate with asbestos. Asbestos carcinogenesis and mesothelioma have been linked…
KATP channels are metabolic sensors that translate intracellular ATP/ADP balance into membrane excitability. The molecular composition of KATP includes an inward-rectifier potassium channel (Kir) and an ABC transporter–like sulfonylurea receptor (SUR). Although structures of KATP have been determined in many conformations, in all cases, the pore in Kir is closed….
Amyloid fibrils are associated with a number of neurodegenerative diseases, including fibrils of amyloid β42 peptide (Aβ42) in Alzheimer's disease. These fibrils are a source of toxicity to neuronal cells through surface-catalyzed generation of toxic oligomers. Detailed knowledge of the fibril structure may thus facilitate therapeutic development. We use small-angle…
Lipid membranes are complex quasi–two-dimensional fluids, whose importance in biology and unique physical/materials properties have made them a major target for biophysical research.

People who live near the Great Lakes might go there to enjoy a swim or a boat ride. But if you're visiting from the National Institute of Standards and Technology (NIST), you might go boating for science.
Research conducted at Lawrence Livermore National Laboratory (LLNL) is taking a closer look at entropy—the measure of internal energy per unit temperature that is unavailable for doing useful work—in experiments at the National Ignition Facility (NIF).
So one thing I've been trying to understand recently is how people — specifically fans get so intensely emotionally invested in sports teams. I'm not immune to this myself as I also have teams which I root for. I get happy when they win and sad when they lose, but I usually get over it pretty quickly. I know lots fans who get significantly more into than I do, even for sports we both love. They p
From a viewpoint about 90 kilometers (56 miles) above Lacus Veris, "Lake of Spring," the camera aboard NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft imaged Saturn on October 13, 2021. In this view, the Lunar Reconnaissance Orbiter Camera (LROC) was looking down at the north face of the rings, and from this perspective the rings in front of Saturn appear below its equator.

Placentas from mothers of healthy newborns could one day be used to reduce brain injury in growth-restricted babies, according to new research. The findings show that stem cells sourced from a healthy placenta may reduce damaging inflammation in these babies after only three days. "There is currently no treatment to protect the brains of a growth-restricted baby," says Julie Wixey from the Centre
Sugars interact with the cell surface through sugar-binding proteins called lectins. These interactions play a fundamental role in many of the cell's biological processes. One important function is the modulation of the immune response towards an outside threat. In a recent Nature Chemical Biology paper, ICMS researchers team up with researchers from Leiden University to unravel the interactions o
It's been a year since America experienced one of its most divisive elections in decades. Although President Joe Biden has called for unity, recent data from a new measurement, the USC Polarization Index, has shown political polarization remains as bad today as it was a year ago.
A triboelectric nanogenerator (TENG) is an energy-harvesting device that converts mechanical energy into electricity through contact separation or relative sliding movements of two opposite tribo-polar materials. Researchers from Inha University previously reported the first example of sulfur backbone polymer-based TENG. The surface of the sulfur copolymer film was directly fluorinated using toxic
Alkynes have many uses in industry. Until now, it was assumed that gold- or platinum-based catalysts were absolutely necessary for certain chemical reactions with alkynes. Chemists at Martin Luther University Halle-Wittenberg (MLU) have now succeeded in carrying out the same reactions with considerably less expensive materials. The team reports on its work in the Journal of the American Chemical S
Scientists use superconducting detectors (MKIDs) to discern the spectrum of exoplanets from their faint glow.

After decades of sowing doubt about climate change and its causes, the fossil fuel industry is now shifting to a new strategy: presenting itself as the source of solutions. This repositioning includes rebranding itself as a "carbon management industry."
For the past 17 years, China has imported more agricultural products than it has exported. Finding ways to improve the export competitiveness of its agricultural products has been a pressing challenge for China since it joined the World Trade Organization (WTO) in 2001. To date, research into the issue has largely focused on the macro perspective; little research has been conducted from a micro po
The bifunctional catalysts consisting of spinel ZnAlOx and SAPO-11 zeolite can directly convert syngas (a mixture of H2 and CO) into high-quality gasoline. The selectivity of C5–C11 gasoline-range hydrocarbons can reach 79% with a high content of iso-paraffins. The formation of iso-paraffins over ZnAlOx/SAPO-11 catalyst follows a pore-mouth catalysis mechanism, which means the isomerization of lin
Although we usually do not realize this, lighting is an essential part of our daily lives. After all, without light, no sight. Next to enabling us to see safely and comfortably move from place A to B, lighting also has a large impact on how we perceive and appreciate spaces.

Forskare har "filmat" hur ett protein, som reglerar energibalansen i cellen, förändrar sin struktur för att katalysera en kemisk reaktion. De molekylära mekanismerna som ligger till grund för hur en cell styr energikonsumtion och lagring är ännu inte helt kända. – Vår studie presenterar nya rön för en välkänd enzymatisk reaktion i cellen. Studien bidrar till den generella förståelsen av hur prote
The international climate summit in Glasgow aimed to "consign coal power to history". But while some major coal-consuming countries have agreed to phase out the fossil fuel in the 2030s, Australia is not one of them.
Psychedelics have always been around, and millions of people have turned to them for healing and personal growth, outside the designs of the law. Now they are back with renewed force, supported by scientific studies that empirically demonstrate the efficacy of 'medicines' such as MDMA, ayahuasca, ketamine or psilocybin , the molecule that confers the attribute of "magic" to mushrooms. submitted b
Why is NASA planning on deliberately crashing a spacecraft into a small asteroid that poses no threat to the Earth? It's a test of an asteroid deflection system – DART (Double Asteroid Redirection Test) . Why the "double"? Most articles on the topic don't say, and I had two hypotheses. The first is that the mission is targeting two asteroids, or actually a binary asteroid, Didymos (Greek for "twi
The New Puritans A growing illiberalism, fueled by social media, is trampling democratic discourse, Anne Applebaum argued in October. The result is a chilling atmosphere in which mob justice has replaced due process and forgiveness is impossible. The paramount value of the university has always been academic freedom, the freedom of university departments and professors to decide what to teach and

Ants are among the most diverse and abundant insects on the planet. Both native and invasive ants are capable of forming mutualisms with hemipteran insects, preying on non-hemipteran herbivores and indirectly affecting primary production. To date, most research has focused on only one or two levels of interaction between ants, other arthropods, and plants, and few studies have focused on the poten
Projections of the Earth's future climate at a finer scale are important in climate-related studies. However, the typical spatial resolution of CMIP6 models is approximately 100 km, which is not sufficient for resolving fine-scale orography, land cover and dynamics of the atmosphere, hindering their ability to simulate extreme weather and climate events.
Shigella, a bacterial pathogen that causes dysentery and is the leading cause of childhood diarrheal diseases, inserts a pore called a translocon into an infected person's intestinal cells and then injects bacterial proteins into the cells. There, the proteins hijack the cells' machinery to help Shigella multiply. In a study published in mBio, a team at Massachusetts General Hospital (MGH) has unc

Efficient and targeted sperm motility is essential for animal reproductive success. Sperm from mammals and echinoderms utilize a highly conserved signaling mechanism in which sperm motility is stimulated by pH-dependent activation of the cAMP-producing enzyme soluble adenylyl cyclase (sAC). However, the presence of this pathway in early-branching metazoans has remained…
Calcium (Ca2+) homeostasis is maintained through coordination between intestinal absorption, renal reabsorption, and bone remodeling. Intestinal and renal (re)absorption occurs via transcellular and paracellular pathways. The latter contributes the bulk of (re)absorption under conditions of adequate intake. Epithelial paracellular permeability is conferred by tight-junction proteins called claudin
In the laboratory, animals' motivation to work tends to be positively correlated with reward magnitude. But in nature, rewards earned by work are essential to survival (e.g., working to find water), and the payoff of that work can vary on long timescales (e.g., seasonally). Under these constraints, the strategy of…
Physicochemical principles such as stoichiometry and fractal assembly can give rise to characteristic scaling between components that potentially include coexpressed transcripts. For key structural factors within the nucleus and extracellular matrix, we discover specific gene-gene scaling exponents across many of the 32 tumor types in The Cancer Genome Atlas, and…
Synaptotagmin 1 (syt1) is a Ca2+ sensor that regulates synaptic vesicle exocytosis.

By the late 21st century, northeastern U.S. cities will see worsening hurricane outcomes, with storms arriving more quickly but slowing down once they've made landfall. As storms linger longer over the East Coast, they will cause greater damage along the heavily populated corridor, according to a new study.
Astronomers have discovered two previously invisible galaxies 29 billion light-years away. Their discovery suggests that up to one in five such distant galaxies remain hidden from our telescopes, camouflaged by cosmic dust. The new knowledge changes perceptions of our universe's evolution since the Big Bang.
Researchers explain why digital teaching cannot replace face-to-face teaching in university education, but can certainly be seen as a complementary tool. The future of teaching and learning may lie in so-called blended learning, a mix of face-to-face and online education.
Some ancestral rodents likely had repeated infections with SARS-like coronaviruses, leading them to acquire tolerance or resistance to the pathogens, according to new research. This raises the possibility that modern rodents may be reservoirs of SARS-like viruses, the researchers say.

As our world becomes increasingly digital, math becomes more and more important (not that it wasn't always important). Even in ancient times, math was a critical technology improving our ability to predict the seasons, design buildings and roads, and have a functioning economy. In recent decades our world has been becoming increasingly virtual and digital, run by mathematical algorithms, simulati
A new study suggests that the brain may treat similar environments as if they are even more different than a pair of environments that have nothing in common. Brain scientists call this concept "repulsion." For example, imagine you're walking through a chain supermarket, headed for the dairy section. You've done it a million times: Take a right at the entrance, away from the produce, and walk pas

A new analysis adds to evidence that nutritious diets are often more environmentally sustainable, while also demonstrating the feasibility of evaluating diet sustainability at the scale of specific foods—rather than broader food-group categories. Dr. Holly Rippin of the University of Leeds, U.K., and colleagues present these findings in the open-access journal PLOS ONE on November 24, 2021.
The critical zone is Earth's outer skin, the space between treetops and bedrock. The critical zone is a community comprising rock, water, soil, air, and the flora and fauna that live on Earth's surface. As floods, landslides, and other geologic hazards shape landscapes, they transform the critical zone and the life-giving processes that support ecosystems.
The Department of Agronomy at the University of Córdoba leads an international study in which the different species of the pathogen are being understood thanks to samples collected over the course of 25 years.
I princip allt som säljs i frukt- och grönsaksdisken har kommit till genom växtförädling, något som få konsumenter har kunskap om, visar en studie från SLU. Ändå är åsikterna många, vilket kan påverka utvecklingen av nya sorter. Det finns en tydlig skillnad mellan män och kvinnor i synen på växtförädling. Män är i allmänhet mer positiva både till konventionell växtförädling och till modern gentek
Legislation that enforces a 'cooling off' period between purchasing and acquiring a firearm reduces impulse purchases. It also limits the number of homicides, especially in the domestic sphere. This is demonstrated by behavioral economist David Schindler of Tilburg University on the basis of a quantitative study in various U.S. States. The publication will appear in the journal Review of Economics

Nature, Published online: 19 November 2021; doi:10.1038/d41586-021-03504-4 NASA will slam a multimillion-dollar spacecraft into an asteroid to test whether it is possible to change a space rock's trajectory. Plus, childhood colds might change how the immune system responds to COVID.
When the COVID-19 pandemic forced New Orleans public school teachers to switch from in-person instruction to a virtual or hybrid setting, the transition left many feeling anxious over their ability to impact student learning, according to a multi-agency study led by Tulane University.
Policymakers, industry and civil society leaders count on solid data to inform and guide strategies that will deliver on the objectives of the Paris Agreement. To support these decisions, scientists developed long-term global scenarios known as integrated assessment models (IAMs) that combine different strands of knowledge—natural science, engineering and economics.
In an age of online restaurant reviews and product ratings, landing in first place on a "top 10" list can confer great benefits on the top-ranked option, magnifying the differences between it and all other choices and blinding people to important details that might otherwise affect their decision-making, according to research published by the American Psychological Association.
Women are structurally underrepresented in leading management and organization journals, a new study published today in Research Policy finds. Nora Lohmeyer(verwijst naar een andere website) of Radboud University and Carolin Auschra and Julia Bartosch of Freie Universität Berlin analyzed a dataset of 43,673 articles in fourteen top journals, and found that even in 2017, the most recent year of the
Den vanligaste använda metoden att testa för covid-19 är med RT-PCR genom ett nässvalgsprov taget med bomullspinne. Provtagning från nässvalget är ofta obehaglig och RT-PCR-test kräver även analys i laboratorium. I en ny studie från Lunds universitet har forskare undersökt om snabbantigentest för covid-19 kan användas på saliv i stället för att pinna nässvalget.
We've been hearing a lot recently about the metaverse—a vision for the internet which uses technology like virtual and augmented reality to integrate real and digital worlds. With Facebook changing its name to Meta to focus on this space, and other big tech companies like Microsoft coming onboard, there is much discussion about the potential of the metaverse to enhance the way we socialize, work a
News that describes migration in a positive context, makes us become more positive about immigration and vice versa. This is stated by Nora Theorin in a new dissertation on media and migration at the Department of Journalism, Media and Communication, University of Gothenburg.
Omega Protein Corp and Omega Protein, Inc. may not be household names, but many of their products are. These two companies, collectively known as "Omega," compose one of the largest reduction fishing organizations in North America. They capture and process fish known as menhaden, then resell the "reduced fish" for use in pet food, agriculture and aquaculture feed, and human fish oil supplements. B
On the face of it, a recently launched TV channel dedicated to dogs seems, well, barking mad. But our pets often spend long periods of time home alone, and providing some form of enrichment and stimulation can be very beneficial to dogs and their owners alike.
We tend to think Antarctica is isolated and far away—biologically speaking, this is true. But the continent is busier than you probably imagine, with many national programs and tourist operators crisscrossing the globe to get there.
Warning Twitter users about potential adverse consequences of their use of hate speech can decrease their subsequent posting of hateful language for a week, finds a new study by New York University's Center for Social Media and Politics.
Even though we can't see it, harmful bacteria are everywhere. While we can't control the germs that live outside of our homes , we can control the ones that live among us, to some extent. One viable way to combat harmful germs from spreading in your house is using a sterilizing robot. Yes, a robot that kills germs. The ROCKUBOT is a high-tech robot buddy that eliminates germs and airborne viruses
Var åttonde person i åldern 16-25 år har använt eller använder preparat som är muskelbyggande eller har som syfte att förändra kroppens utseende enligt en studie från Högskolan i Gävle. Att cirka 12 procent ungdom har tagit preparat för att förändra sin kropps utseende var en oväntat hög siffra för Anna Qvarfordt, Lena Svennberg och Göran Svedsäter, forskare inom Idrottsvetenskap vid Högskolan i
Nyheter som beskriver invandring i ett positivt sammanhang, får oss att bli mer positivt inställda till invandring och tvärtom. Det gäller framför allt "alternativa medier" på höger- och vänsterkanten. Medier sägs ofta spela en central roll för vad människor anser om migration, men kunskapen är begränsad om hur, när och varför de påverkar. I sin doktorsavhandling har Nora Theorin undersökt instäl

Globala IT-företag har vunnit terräng inom skolan under pandemin. Att kommersiella krafter tar sig in i utbildningssystemets kärna och påverkar hur undervisningen bedrivs är olyckligt, anser Malin Ideland, professor i utbildningsvetenskap. Digitaliseringen fungerar dessutom som IT-jättarnas spionkamera in i svenska klassrum, skriver hon.
New research published in Frontiers in Education argues that analyzing the individual components that underlie socioeconomic status, such as parents' occupation or the number of books in a home, is a better predictor of student success across different cultures than the current composite index.
Nature, Published online: 22 November 2021; doi:10.1038/d41586-021-03491-6 Carbon-neutrality institutes, and other initiatives to support a pledge to achieve net zero by 2060, are popping up like mushrooms across China.

Broad-based scientific team from government, academia and industry joins forces to identify new opportunities to reduce the environmental impact of polyurethane — one of the most widely used but little recycled plastic materials.
I completed my undergrad from a large state college in the United States with a 3.9 in computer science and mathematics; otherwise, I have a rather sparse resume when it comes to lab experience or academic research, and I don't have anyone that could write me a good recommendation (I was a bit of an underachiever despite my GPA). I was interested in going to work as a programmer, so I focused my
Researchers have developed an ultra-thin wireless device that grows to the surface of bone. Dubbed 'osseosurface electronics,' they could someday help physicians monitor bone health and healing over long periods.
Alexander disease is a progressive and rare neurological disorder with no cure or standard course of treatment. But a new study involving a rat model of the disease offers a potential treatment for the typically fatal condition.
It sounds like a party trick: scientists can now look at the brain activity of a tiny worm and tell you which chemical the animal smelled a few seconds before. But the findings of a new study are more than just a novelty; they help the scientists better understand how the brain functions and integrates information.
Exotic laser-produced high-energy-density (HED) plasmas akin to those found in stars and nuclear explosions could provide insight into events throughout the universe. Physicists have discovered a new way to measure and understand these plasmas, among the most extreme states of matter ever produced on Earth. Improved understanding could provide benefits ranging from fine-tuning the high-density pla
A team of researchers has demonstrated for the first time one way that a small molecule turns a single cell into something as large as a tree. For half a century, scientists have known that all plants depend on this molecule, auxin, to grow. Until now, they didn't understand exactly how auxin sets growth in motion.
In the human brain, the hormone insulin also acts on the most important neurotransmitter for the reward system, dopamine. Insulin lowers the dopamine level in a specific region of the brain (striatum) that regulates reward processes and cognitive functions, among other things. This interaction can be an important driver of the brain's regulation of glucose metabolism and eating behavior.
Global change is eroding life on earth at an unprecedented rate and scale. Species extinctions have accelerated over the last decades, with the concomitant loss of the functions and services they provide to human societies.
