Wretched Garbage Planet We've got a huge space junk problem — and it's only going to get worse as more and more companies and governments launch satellites, spacecraft, probes, and even tourists into space. While much of what we send to orbit ends up getting sucked back into the Earth's atmosphere to burn up, much of it remains — until we figure out how to do something about it. Things could get
The petrochemical industry turns oil and gas into precursors used to synthesize lubricants and other critical products. Chemists show that bacteria can be metabolically engineered to generate similar precursors, providing a sustainable replacement for fossil fuels and using less energy. The microbes need only glucose. The medium-chain hydrocarbons they produce can be broken down into shorter chain

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
Scientists sceptical about Pascal Soriot's suggestion Oxford jab may give longer-lasting protection Coronavirus – latest updates See all our coronavirus coverage Scientists have reacted with scepticism to claims by AstraZeneca's CEO that low uptake of the Oxford/AstraZeneca jab among elderly Europeans could explain the current surge in Covid-19 infections in mainland Europe. Pascal Soriot told BB
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.
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.
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.
Asteroid Slam NASA is launching a spacecraft destined to slam into an asteroid as part of its Double Asteroid Redirection Test (DART) mission tonight, from the Vandenberg Space Force Base in California. Its purpose: to test whether we're capable of deflecting a killer asteroid before it strikes Earth. But before it meets its final destination, NASA is using the spacecraft to test out brand new io
Researchers found chores could help prevent disease and falls, though other experts have urged caution Household chores might seem a drag, but researchers have suggested tasks like dusting, scrubbing floors and washing the windows might help adults to stay healthy into old age. Writing in the journal BMJ Open, a Singapore-based team of researchers said regular physical activity "improves physical
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

In House of Gucci , opulence is not always alluring. But Ridley Scott's new movie takes its time before delving into the insidious, gilded world of the Italian luxury label. The film, which charts the turbulent marriage of the fashion heir Maurizio Gucci (played by Adam Driver) to the ambitious Patrizia Reggiani (Lady Gaga), instead opens with the pair's gentle romance. 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

E lection Night almost killed Latinx . As results started trickling in, media figures and political strategists struggled to process what they were seeing in Florida and Texas. The "blue wave" that polls had suggested would punish Republicans was instead showing a dramatic shift in Latino-voter support toward the GOP. What could explain this? Democrats' embrace of "wokeness" and, in this case, us
In 1993, a SWAT team equipped with night-vision goggles and assault rifles surrounded Mel Gibson's mansion under the cover of darkness. 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.
In recent years, many physicists worldwide have been investigating the behavior of hybrid nanostructures. These are systems that are typically made up of two or more materials. Special attention in this class of structures is paid to magnetic impurities interacting with superconducting and normal metallic contacts.

An FDA-approved drug for hepatitis C can increase bacterial sensitivity to antibiotics and reduce the likelihood of antibiotic resistance, according to a new study led by New York University researchers published in Cell Chemical Biology. The drug called telaprevir works by blocking the function of chaperones—important proteins that fold other proteins in the cell—in bacteria.
Copper in small quantities is an essential nutrient but can also be toxic. Human immune cells use copper to fight invading pathogens. Some microorganisms, in turn, have evolved ways to take up copper and incorporate it into biological molecules, either as a way to absorb copper for nutrition or to neutralize its toxic effects.

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.

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.
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 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
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).

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.
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

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

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.

Nonhormonal products for on-demand contraception are a global health technology gap; this unmet need motivated us to pursue the use of sperm-binding monoclonal antibodies to enable effective on-demand contraception. Here, using the cGMP-compliant Nicotiana-expression system, we produced an ultrapotent sperm-binding IgG antibody possessing 6 Fab arms per molecule that bind…
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.

The extraordinary record was just published in the peer-review
The plant-based/meat alternative market has been growing for years, but it was during the pandemic that its profile soared. Meat substitutes remain relatively niche products, however. So how can its proponents break through to consumers?
There is an eternal question when hiring: "Is this person really the right fit?" Even if a candidate has the skills for the job, does their personality fit the company culture? Do their goals align with those of the organization? In the very short span of a selection process, it is very difficult to get to know the person behind the mask and find the answers to these questions. A new paper publish
Complex systems can be found in a diverse array of real-world scenarios, but are unified by their ability to suddenly transition between drastically different patterns of behavior. Known as 'tipping,' this type of transformation is generally triggered by small changes in the parameters of individual systems—whose effects can rapidly cascade to alter entire networks of interacting subsystems.

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. Now, researchers from SRON Netherlands Institute for Space Research and TU Delft have observed 100 times lower noise than expected, providing a new fundamental physics insight: the relationship between the number of quasiparticles and their lifetime vanishes. The study has been published i

The use of electrodes placed inside the brains of laboratory specimens has pushed the field of neuroscience to new findings for decades. Common silicon-based electrodes rely on established production methods but are stiff and prone to injuring the brain. More pliable polymer-based electrodes avoid these issues but are difficult to scale, especially when integrating light emitters for neuron stimul
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. Ph.D. student Adrie de Vries has investigated how lighting affects the experience and performance of knowledge workers in an
The impacts of invasive alien species, habitat loss and climate change are compounded in small island nations, which are highly dependent on biodiversity for their economic and social wellbeing. The failure to meet global biodiversity targets clearly indicates the need for more effective biodiversity management and conservation efforts, and this in turn requires better understanding of the current
