An exotic form of magnetism has been discovered and linked to an equally exotic type of electrons, according to scientists who analyzed a new crystal in which they appear at the National Institute of Standards and Technology (NIST). The magnetism is created and protected by the crystal's unique electronic structure, offering a mechanism that might be exploited for fast, robust information storage
In 1998, the journal Nature published a seminal letter concluding that a mysterious signal, which had been discovered while analyzing the polarization of sunlight, implies that the solar chromosphere (an important layer of the solar atmosphere) is practically unmagnetised, in sharp contradiction with common wisdom. This paradox motivated laboratory experiments and theoretical investigations, which
Japanese space agency scientists said Thursday they plan to bring soil samples back from the Mars region ahead of the United States and China, which started Mars missions last year, in hopes of finding clues to the planet's origin and traces of possible life.
A new study led by the University of Colorado Boulder reveals the complex history behind one of the Grand Canyon's most well-known geologic features: A mysterious and missing gap of time in the canyon's rock record that covers hundreds of millions of years.
Among the fierce carnivores that lived during the late Cretaceous was a predator named Daspletosaurus. The massive tyrannosaur, about nine meters long, lived in the coastal forest of what is now Alberta around 75 million years ago—-preceding the more famous T. rex by about 10 million years.
It's suspected that about 5,000 years ago a comet may swept within 23 million miles of the Sun, closer than the innermost planet Mercury. The comet might have been a spectacular sight to civilizations across Eurasia and North Africa at the end of the Stone Age.
When people ask me what I did in Afghanistan, I tell them that I hung out in planes and listened to the Taliban. My job was to provide "threat warning" to allied forces, and so I spent most of my time trying to discern the Taliban's plans. Before I started, I was cautioned that I would hear terrible things, and I most certainly did. But when you listen to people for hundreds of hours—even people
Ring of Explosions Japan's space agency JAXA has announced that is has successfully demonstrated the operation of a "rotary detonation engine" in space, a world's first. Such an engine uses a series of controlled explosions that travel around a circular channel at its base. The result is a massive amount of thrust coming from a much smaller engine using significantly less fuel — a potential game
Didier Raoult, who promoted hydroxychloroquine treatment, may not be able to continue his research The French scientist who promoted the discredited hydroxychloroquine treatment for Covid-19 backed by Donald Trump faces being pushed out of the infectious diseases institute he founded, amid concerns from key members over its role in feeding conspiracy theories and an investigation by regulators in
Back in April, The Nation magazine told readers that the withdrawal of American troops from Afghanistan would be " a welcome and long-overdue action ." The essay, by a scholar named Phyllis Bennis, sounded upbeat, even salubrious. It was the liberal case in full: We Americans were a wretched people to have gone there and a depraved people to have stayed for two decades. Some collateral damage upo

Inmates who scored high in antisocial traits — a facet of psychopathy — tended to keep their heads still. Could you spot a psychopat
A team of mad scientists successfully 3D-printed out a living, "viable" glioblastoma tumor — the deadliest kind of brain cancer — for the express purpose of learning how to kill it. The tumor, which is made of a brain-like material and artificial blood vessels, is likely the most realistic approximation of glioblastoma available for doctors to work with, according to research published in the jou
Graph theory isn't enough. The mathematical language for talking about connections, which usually depends on networks — vertices (dots) and edges (lines connecting them) — has been an invaluable way to model real-world phenomena since at least the 18th century. But a few decades ago, the emergence of giant data sets forced researchers to expand their toolboxes and, at the same time… Source

Updated on August 19 at 12:45 p.m. ET The Afghans were not ready to leave. That was how President Joe Biden, in his address to the nation on Monday , tried to explain why his administration had not acted sooner, and faster, to evacuate America's allies from Afghanistan ahead of the Taliban's rapid march to Kabul. Many of the local partners who aided the U.S. military during its 20-year war—interp

Scientists around the world are developing new hardware for quantum computers, a new type of device that could accelerate drug design, financial modeling, and weather prediction. These computers rely on qubits, bits of matter that can represent some combination of 1 and 0 simultaneously. The problem is that qubits are fickle, degrading into regular bits when interactions with surrounding matter in

As a medical historian, I have never been busier. Over the past 20 months, journalists and policy makers have reached out in an effort to understand what past infectious diseases might teach us about this one. These exchanges almost always end with questions about how this pandemic is similar to the influenza pandemic of 1918–19, which, until COVID-19, was the worst pandemic in human history. The
TikTok's hottest new trend? Dangerous COVID-19 misinformation. It's not a surprise that misinformation is spreading so rampantly on the social media platform, which promotes a rapid-fire onslaught of video so unrelenting it's amazing anyone can walk away with any semblance of an attention span intact. It's also unsurprising to anyone who's studied media or misinformation that COVID-19 and the vac

When some European elite football leagues returned to action last year amidst the pandemic, athletes played largely without crowds. These so-called ghost games offered researchers a rare opportunity to get into the heads of referees. What they found was that football officials—no longer pressured by fans—penalized only the home team with more yellow cards after fouls, with the apparent knock-on ef
Researchers at the University of Bristol have shown how laboratory evolution can give rise to highly efficient enzymes for new-to-nature reactions, opening the door for novel and more environmentally friendly ways to make drugs and other chemicals.
Ever since people started slinging around the word basic as an insult, delights as disparate as pumpkin-spice lattes, the music of Lizzo, and sunsets have gotten a bad rap. The diss refers to pleasure—simple pleasures, normal pleasures, things that everyone can enjoy. What makes you happy, the notion of "basic" says, can also make you boring. Lorde has allegedly become basic. The New Zealand song
The problem of other minds asks how it is that we can be sure that other people have mental lives when we can only infer that this is the case from behavior and testimony. John Stuart Mill argued that we know others' minds by analogy, but is this a strong argument? With artificial intelligence and animated movies, what grounds do we really have for ascribing mindedness to sentient-looking beings?
New research from Florida State University and Rice University is providing a better estimate of the amount of carbon in the Earth's outer core, and the work suggests the core could be the planet's largest reservoir of that element.
Scientists have measured thousands of nearby stars and far away galaxies that have never been identified before at radio wavelengths, while studying a galactic body that neighbors our own Milky Way galaxy—the Large Magellanic Cloud.
Millions of solar panels have been installed in the last two decades—and since they typically last between 25 and 30 years, many will soon be ready for retirement and probably headed to a landfill. But new efforts to recycle these panels could reduce both the amount of waste and the new material that needs to be mined. Only about 10% of panels in the US are recycled—it isn't mandated by federal r

White clover is a weed that grows the world over—there's a good chance you have some growing in your yard today. The plant that yard-preeners love to hate was spawned about 20,000 years ago when two European clover species hybridized.
Deep in the dense coastal forests and marshes of the American Southeast lie shell rings and shell mounds left by Indigenous people 3,000 to 5,000 years ago. Now an international team of researchers, using deep machine learning to assess remote sensing data, has located previously undiscovered shell rings. The researchers hope this will lead to a better understanding of how people lived in that are

The average Afghan is 18 years old . Nearly two-thirds of the country is under 25 . For these young people, the 2001 American invasion and the Taliban reign that preceded it aren't memories, but history. Theirs is a generation that has known Afghanistan only under the protection of NATO forces. Twenty years later, the Taliban has returned to power in a country unlike the one it previously control
Afghanistan's banking system is in a state of collapse, and people throughout the country are running out money. And this cash crisis—partly due to the international community's efforts to starve the Taliban of resources—is having an outsized effect on everyday Afghan citizens, leaving many without access to important services as the UN warns of a growing humanitarian disaster .

Humans were thought to have the longest primate strides for their height, but now it turns out that chimpanzees take 25% longer strides than we do, thanks to their swiveling hips, which rotate by as much as 61deg every time they take a step to compensate for their crouched posture and shorter legs.
It has become a term for a general gaffe, but the true joy is in its original form Sigmund Freud has his fans and his detractors. My take? A lot of his work was pioneering and has relevance to this day; a lot of it was nonsense. One of Freud's greatest legacies (no, not the scatology obsession) is the one that bears his name: the Freudian slip. (Or parapraxis, to give it its other name.) When Fre

Den nye bog 'Akutlægens dagbog' er et så virkelighedsnært portræt af akutlægelivet, at man får gåsehud, tårer i øjenkrogene og en følelse af at være så tæt på, at man kan mærke og sanse akutlægens levede liv under COVID-19-pandemien. Bogen er ikke kun for akutlæger, men også for kolleger fra andre specialer og politikere, der vil have større indsigt i akutlivet og dets udfordringer.
I Danmark har vi stort set valgt at gå enegang i forhold til synet på ME, også kaldet kronisk træthedssyndrom. Mens vores nabolande og mange andre følger WHO's kriterier, fastholder Sundhedsstyrelsen, at ME er en funktionel lidelse, hvilket har store konsekvenser for patienter og pårørende.
De fleste kender de otte folkesygdomme, som er karakteriseret ved, at de har stor udbredelse i befolkningen og er forbundet med væsentlig sygdomsbyrde og risiko for forkortet levetid. Måske vi burde tilføje multisygdom som den niende folkesygdom?
Danske læger har undersøgt muligheden for at erstatte behandling med Prolia med Aclasta til patienter med knogleskørhed. Desværre ser det ikke ud til, at Aclasta kan forhindre tab af knoglemineral, når behandlingen erstatter behandling med Prolia, men forsøget har dog alligevel ført til behandlingsændring for nogle patienter på AUH.

Danmarks Bedste Hospital: Psykiatri: Depressionsdatabasen peger i lighed med de øvrige databaser inden for psykiatrien på, at det er de lokale ledelser, som skal prioritere indberetninger til databaserne væsentligt højere, end det er tilfældet nu.
Down the road, diabetes patients might do away with regular injections or infection-prone insulin pumps and might instead supply a robotic docking station in their guts with regular shipments of insulin pills. A team of engineers developed a small robot that can be implanted into the small intestine that pulls magnetic pills full of insulin toward them, extracts the medicine, and distributes it t
Nature, Published online: 19 August 2021; doi:10.1038/d41586-021-02286-z Addressing weaknesses and limitations in your science will reassure potential funders, say grant-writing coaches Jennifer L. Wilson and Crystal M. Botham.
I mean being able to regenerate the eye in the same vein as regenerating limbs. I know that scientists figured out how to get hair to grow again and will do human trials soon. Scientists have also grown optic nerves again with in a research trial with some patients' eyes even adding additional nerves. There was also a successful study where scientists were able to grow 3D corneas for a transplant
Last time I physically stepped foot into a fast food restaurant was when I was a little kid. I always just do drive through to save myself a little hassle. Today the drive through line at this McDonald's by my house was incredibly long, so I decided to park and go inside. I was shocked by how different the inside of McDonald's was. First, there was not a single cashier to be found. There was one
Hello, I've been doing a lot of research and it seems like most jobs will be automated by 2050 – a very select group of people will have jobs and the rest will be on a universal basic income. According to Jeff Bezos at his Blue Origin presentation he basically said this will be a major time of creativity and innovation. I guess my question is, how can someone in their 20s or 30s prepare for this?
Everyone knows that real estate can be a great investment, if you can afford it. It's a relatively reliable hedge against a sometimes volatile economy, and single family units are an especially enticing way to get in on the action. But where such investments have historically been complicated and even tedious, Roofstock has made the process as simple and easy as possible, so you can focus on enjo
More Delays Blue Origin has won a "stay" after the Jeff Bezos-led space company sued NASA over losing the agency's Human Landing Systems (HLS) contract to competitor SpaceX, according to recent tweets Washington Post space reporter Christian Davenport — a decision that could result in months of delays. That means SpaceX and NASA's work on its lunar lander Starship variant is yet again being put o
Storm Clouds Ahead For the first time in recorded history, it rained at Greenland Summit Camp, a research outpost in the island's (usually) frozen ice shelf. And it wasn't just a little slush. A torrential downpour containing 7 billion tons of rain washed away a horrifying amount of Greenland's ice last week, Earther reports , in a massive melt event that impacted 337,000 square miles — about hal
Research in mice suggests that moderating nerve activity with drugs or electrical pulses could modify tissue immune responses, curtailing the chronic pain often associated with inflammatory conditions.
In order to function properly, the brain requires a steady flow of blood through the cerebral arteries and veins, which deliver oxygen and nutrients and also remove metabolic byproducts. Therefore, cerebral blood flow is considered a vital and sensitive marker of cerebrovascular function. Optical methods offer a noninvasive approach for measuring cerebral blood flow. Diffuse correlation spectrosco
Worldwide, the cost of bird collisions with planes has been estimated at $1.2 billion per year. But information on bird movements throughout the year can help avoid damage to aircraft and risk to passengers. Scientists from the Cornell Lab of Ornithology and partners have been looking for patterns in bird strike data from three New York City area airports. Their findings were published today in th
Researchers have shown how laboratory evolution can give rise to highly efficient enzymes for new-to-nature reactions, opening the door for novel and more environmentally friendly ways to make drugs and other chemicals.

Researchers have found antibodies that protect against specific mosquito-borne viruses that cause arthritis and brain infections. The findings could lead to a universal therapy or vaccine for the viruses.
A team of engineers and physicians has developed a steerable catheter that will give neurosurgeons the ability to steer the device in any direction they want while navigating the brain's arteries and blood vessels. The device was inspired by nature, specifically insect legs and flagella — tail-like structures that allow microscopic organisms such as bacteria to swim.
One of the most valuable forms of forensic evidence in cases of male-perpetrated sexual assault is the presence of semen, either in the form of stains left behind on items or on swabs collected from victims after an offense. To confirm that semen is present, suspected stains are examined under a microscope to see if any sperm cells are visible.
The global spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and the associated disease COVID-19, requires therapeutic interventions that can be rapidly identified and translated to clinical care. Traditional drug discovery methods have a >90% failure rate and can take 10 to 15 y from target identification to…
Recent evidence suggests that vaccination hesitancy is too high in many countries to sustainably contain COVID-19. Using a factorial survey experiment administered to 20,500 online respondents in Germany, we assess the effectiveness of three strategies to increase vaccine uptake, namely, providing freedoms, financial remuneration, and vaccination at local doctors. Our…
α-Synuclein (α-synFL) is central to the pathogenesis of Parkinson's disease (PD), in which its nonfunctional oligomers accumulate and result in abnormal neurotransmission. The normal physiological function of this intrinsically disordered protein is still unclear. Although several previous studies demonstrated α-synFL's role in various membrane fusion steps, they produced conflicting outcomes…
The energy demands of neurons are met by a constant supply of glucose and oxygen via the cerebral vasculature. The cerebral cortex is perfused by dense, parallel arterioles and venules, consistently in imbalanced ratios. Whether and how arteriole–venule arrangement and ratio affect the efficiency of energy delivery to the cortex…
Dendrites play an essential role in the integration of highly fluctuating input in vivo into neurons across all nervous systems. Yet, they are often studied under conditions where inputs to dendrites are sparse. The dynamic properties of active dendrites facing in vivo–like fluctuating input thus remain elusive. In this paper,…
TMEM16A Ca2+-activated chloride channels are involved in multiple cellular functions and are proposed targets for diseases such as hypertension, stroke, and cystic fibrosis. This therapeutic endeavor, however, suffers from paucity of selective and potent modulators. Here, exploiting a synthetic small molecule with a biphasic effect on the TMEM16A channel, anthracene-9-carboxylic…
Range expansions accelerate evolution through multiple mechanisms, including gene surfing and genetic drift. The inference and control of these evolutionary processes ultimately rely on the information contained in genealogical trees. Currently, there are two opposing views on how range expansions shape genealogies. In invasion biology, expansions are typically approximated by…
The properties of topological systems are inherently tied to their dimensionality. Indeed, higher-dimensional periodic systems exhibit topological phases not shared by their lower-dimensional counterparts. On the other hand, aperiodic arrays in lower-dimensional systems (e.g., the Harper model) have been successfully employed to emulate higher-dimensional physics. This raises a general question…
Binary classification is one of the central problems in machine-learning research and, as such, investigations of its general statistical properties are of interest. We studied the ranking statistics of items in binary classification problems and observed that there is a formal and surprising relationship between the probability of a sample…
The dynamics and folding of potassium channel pore domain monomers are connected to the kinetics of tetramer assembly. In all-atom molecular dynamics simulations of Kv1.2 and KcsA channels, monomers adopt multiple nonnative conformations while the three helices remain folded. Consistent with this picture, NMR studies also find the monomers to…
In this paper, we investigate how individuals make time–money tradeoffs in labor contexts in which they are either asked to work to earn money or to pay money to avoid work. Theory predicts that exchange rates between time and money are invariant to the elicitation method. Results from our experiments,…
Growing evidence indicates that gut microbiota play a critical role in regulating the progression of neurodegenerative diseases such as Parkinson's disease. The molecular mechanism underlying such microbe–host interaction is unclear. In this study, by feeding Caenorhabditis elegans expressing human α-syn with Escherichia coli knockout mutants, we conducted a genome-wide screen…
During the last decade, translational and rotational symmetry-breaking phases—density wave order and electronic nematicity—have been established as generic and distinct features of many correlated electron systems, including pnictide and cuprate superconductors. However, in cuprates, the relationship between these electronic symmetry-breaking phases and the enigmatic pseudogap phase remains unclea
Pediatric T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive malignancy resulting from overproduction of immature T-cells in the thymus and is typified by widespread alterations in DNA methylation. As survival rates for relapsed T-ALL remain dismal (10 to 25%), development of targeted therapies to prevent relapse is key to improving…
In this work, a transformation, which maps the mean velocity profiles of compressible wall-bounded turbulent flows to the incompressible law of the wall, is proposed. Unlike existing approaches, the proposed transformation successfully collapses, without specific tuning, numerical simulation data from fully developed channel and pipe flows, and boundary layers with…
Inaccurate expression of the genetic code, also known as mistranslation, is an emerging paradigm in microbial studies. Growing evidence suggests that many microbial pathogens can deliberately mistranslate their genetic code to help invade a host or evade host immune responses. However, discovering different capacities for deliberate mistranslation remains a challenge…
Rattlesnakes increase their rattling rate as potential threats approach, and this abrupt switch to a high-frequency mode makes listeners, including humans, think they're closer than they actually are, researchers report.
Understanding the response of Himalayan-Karakoram (HK) rivers to climate change is crucial for ~1 billion people who partly depend on these water resources. Policy-makers tasked with sustainable water resources management require an assessment of the rivers' current status and potential future changes. We show that glacier and snow melt are important components of HK rivers, with greater hydrolog
Stochastic fluctuations in gene expression ("noise") are often considered detrimental, but fluctuations can also be exploited for benefit (e.g., dither). We show here that DNA base excision repair amplifies transcriptional noise to facilitate cellular reprogramming. Specifically, the DNA repair protein Apex1, which recognizes both naturally occurring and unnatural base modifications, amplifies ex
DeepMind presented notably accurate predictions at the recent 14th Critical Assessment of Structure Prediction (CASP14) conference. We explored network architectures that incorporate related ideas and obtained the best performance with a three-track network in which information at the one-dimensional (1D) sequence level, the 2D distance map level, and the 3D coordinate level is successively trans
Translation termination, which liberates a nascent polypeptide from the ribosome specifically at stop codons, must occur accurately and rapidly. We established single-molecule fluorescence assays to track the dynamics of ribosomes and two requisite release factors (eRF1 and eRF3) throughout termination using an in vitro–reconstituted yeast translation system. We found that the two eukaryotic rele
Eukaryotic genomes contain domesticated genes from integrating viruses and mobile genetic elements. Among these are homologs of the capsid protein (known as Gag) of long terminal repeat (LTR) retrotransposons and retroviruses. We identified several mammalian Gag homologs that form virus-like particles and one LTR retrotransposon homolog, PEG10, that preferentially binds and facilitates vesicular
Understanding the causes and consequences of the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern is crucial to pandemic control yet difficult to achieve because they arise in the context of variable human behavior and immunity. We investigated the spatial invasion dynamics of lineage B.1.1.7 by jointly analyzing UK human mobility, virus genomes, and c
The impact of unconventional oil and gas development on water quality is a major environmental concern. We built a large geocoded database that combines surface water measurements with horizontally drilled wells stimulated by hydraulic fracturing (HF) for several shales to examine whether temporal and spatial well variation is associated with anomalous salt concentrations in United States watersh
The interfaces of perovskite solar cells (PSCs) are important in determining their efficiency and stability, but the morphology and stability of imbedded perovskite-substrate interfaces have received less attention than have top interfaces. We found that dimethyl sulfoxide (DMSO), which is a liquid additive broadly applied to enhance perovskite film morphology, was trapped during film formation a
Many correlated systems feature an insulator-to-metal transition that can be triggered by an electric field. Although it is known that metallization takes place through filament formation, the details of how this process initiates and evolves remain elusive. We use in-operando optical reflectivity to capture the growth dynamics of the metallic phase with space and time resolution. We demonstrate
In human-made malleable materials, microdamage such as cracking usually limits material lifetime. Some biological composites, such as bone, have hierarchical microstructures that tolerate cracks but cannot withstand high elongation. We demonstrate a directionally solidified eutectic high-entropy alloy (EHEA) that successfully reconciles crack tolerance and high elongation. The solidified alloy ha
Zoonotic avian influenza A virus (IAV) infections are rare. Sustained transmission of these IAVs between humans has not been observed, suggesting a role for host genes. We used whole-genome sequencing to compare avian IAV H7N9 patients with healthy controls and observed a strong association between H7N9 infection and rare, heterozygous single-nucleotide variants in the MX1 gene. MX1 codes for myx
Babbling is a production milestone in infant speech development. Evidence for babbling in nonhuman mammals is scarce, which has prevented cross-species comparisons. In this study, we investigated the conspicuous babbling behavior of Saccopteryx bilineata , a bat capable of vocal production learning. We analyzed the babbling of 20 bat pups in the field during their 3-month ontogeny and compared it
The relationship between community prevalence of Plasmodium falciparum and the burden of severe, life-threatening disease remains poorly defined. To examine the three most common severe malaria phenotypes from catchment populations across East Africa, we assembled a dataset of 6506 hospital admissions for malaria in children aged 3 months to 9 years from 2006 to 2020. Admissions were paired with
There is an urgent need for antiviral agents that treat severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We screened a library of 1900 clinically safe drugs against OC43, a human beta coronavirus that causes the common cold, and evaluated the top hits against SARS-CoV-2. Twenty drugs significantly inhibited replication of both viruses in cultured human cells. Eight of these
New research shows how deforestation and population growth have greatly impacted landslide risk in the Kivu Rift. This is what researchers established from an analysis of six decades of forest cover and population trends in the region.
'Growing' electronic components directly onto a semiconductor block avoids messy, noisy oxidation scattering that slows and impedes electronic operation. A new study shows that the resulting high-mobility components are ideal candidates for high-frequency, ultra-small electronic devices, quantum dots, and for qubit applications in quantum computing.
Teenagers who use cannabis frequently may be more likely to have children born preterm, when they become parents up to twenty years later, finds a new study. The research repeatedly assessed 665 participants in a general population cohort on their tobacco and cannabis use between ages 14 to 29 years, before pregnancy.
We have a confession right up front: You won't meet the man — a man who claims to be a brain surgeon, no less — we refer to in the headline. That is because, dear reader, we were not able to contact the person who publishes under the name Michael George Zaki Ghali. What we … Continue reading
The absence of a protein that activates the body's antiviral defenses can cause a rare rheumatoid-like autoinflammatory condition that is treatable with an FDA-approved class of drugs known as TNF (tumor necrosis factor) inhibitors, researchers have found.
Electric vehicles require power to be available anywhere and anytime without delay to recharge, but solar and wind are intermittent energy sources that are not available on demand. And the electricity they do generate needs to be stored for later use and not go to waste. New research reveals a more stable way to store this important energy.
With wind generation one of the fastest-growing renewable energy sectors in the world, experts are using machine learning and other signal processing techniques to characterize annoying noise features from wind farms. Two new publications from the ongoing Wind Farm Noise Study take another step towards improving wind turbine noise assessment methods, guidelines and wind turbine design to make wind
A continuous rise in global population has led to fears that conflicts and war will become more frequent as resources dwindle. But this widespread belief has not been quantified based on actual Japanese archaeological data, until now. Researchers have now examined the skeletal remains of people living in the Middle Yayoi period of Japan to set the record straight on the relationship between popula
As millions of kids head back to the classroom, an expert has advice for how schools can support mental and emotional well-being. After more than a year of remote learning, many students are hoping for a return to normalcy this school year. Yet children will likely face lingering mental health challenges from the pandemic. In one recent survey , 46% of students reported that feelings of depressio
The formation of hybrids—organisms obtained after crossing genetically different forms—is more widespread in nature previously thought. Usually, only closely related species can hybridize. For example, hybrids occur in some populations of Daphnia – crustaceans from plankton. They significantly complicate the definition of the boundaries between different species. However, some cases are known when
A new study reveals that high-grade gliomas, or brain tumors, in dogs contained more immune cells associated with suppressing immune response than low-grade gliomas. The work, which is the most extensive examination of immune cell infiltration in canine glioma to date, adds to the body of evidence that these brain tumors might recruit cells that aid in immunosuppression. The findings could have im

How do you get to work in the mornings? Transport currently accounts for 25 per cent of GHG emissions in European cities. If we are to achieve our emissions targets, one of the things we need to do is change how we get to and from work. An EU project now hopes to influence these choices through nudging.
The global transition to a carbon-neutral economy will cause economic disruption reminiscent of the energy crisis of the 1970s, according to a paper by the Peterson Institute for International Economics.
POSTECH and a group of researchers developed a technology that dramatically improves the performance of plasmonic photocatalysts using 'core@shell' nanocrystals with atomically conformal metal laminations.
At the simplest of levels, nanopores are (nanometre-sized) holes in an insulating membrane. The hole allows ions to pass through the membrane when a voltage is applied, resulting in a measurable current. When a molecule passes through a nanopore it causes a change in the current, this can be used to characterize and even identify individual molecules. Nanopores are extremely powerful single-molecu
New research suggests the feasibility of a 'dream' vaccine that not only protects against SARS-CoV-2 and its known variants of concern, but also future VOCs and other animal coronaviruses with known potential to cause severe disease in humans.
Proteins are the 'tools' of our cells – they are essential to all vital tasks. However, they are only able to do their jobs if they fold correctly and adopt their respective, very specific 3D structure. To ensure that nothing goes wrong with the folding process, it is strictly monitored in the cell. The consequences of a flawed quality control can be seen, for example, in the deposition of misfold
Any time you turn on a light at home or in the office, you are expending electrical energy. But what if flipping the light switch meant providing other useful energy too? We usually think of solar, or photovoltaic (PV), cells fixed to roofs, converting sunlight into electricity, but bringing that technology indoors could further boost the energy efficiency of buildings and energize swaths of wirel
A paper that tried to estimate the cost of invasive species to farming in Africa has been corrected because the researchers made a pair of errors that dramatically inflated their calculations.

The Scientist spoke to marine biologist Tim Lynch, who dusted off 25-year-old data from his PhD to figure out why olive sea snakes approach divers so often. He says the animals, especially the males, likely confuse people for fellow snakes.
A new study predicts that any sea level rise in the world's most southern continent will be countered by an increase in snowfall, associated with a warmer Polar atmosphere. Using modern methods to calculate projected changes to sea levels, researchers discovered that the two ice sheets of Greenland and Antarctica respond differently, reflecting their very distinct local climates.
Adults younger than age 60 who spent eight or more hours a day during their free time using a computer, watching TV or reading and participated in little physical activity had an increased risk of stroke. Boosting physical activity may reduce or eliminate the increased stroke risk from prolonged sedentary time. Public health efforts to increase physical activity and reduce sedentary time in adults
Opioid overdose is a leading cause of injury-related death for adults ages 25 to 54 in the U.S. Recent data suggest that commonly used opioids for pain management may interfere with medications used to manage and treat cardiovascular disease and stroke.
Quantum matter can be solid and fluid at the same time — a situation known as supersolidity. Researchers have now created this fascinating property along two dimensions. They now report on the creation of supersolidity along two axes of an ultracold quantum gas. The experiment offers many possibilities for further investigation of this exotic state of matter.

A new study found that while a 'beauty premium' exists across professions, it's partially because attractive people develop distinct traits as a result of how the world responds to their attractiveness. They build a greater sense of power and have more opportunities to improve nonverbal communication skills throughout their lives.
A new study confirms that for millennia, Indigenous people managed their relationship with shellfish and sea otters to safeguard their access to shellfish which remain important for food, social, and ceremonial uses today.
The proportion of the population exposed to floods has grown by 24% globally since the turn of the century, find researchers. That's 10 times more than scientists previously thought, and it's due to both increased flooding and population migration. This marks an increase of the population inside flood-prone regions to as many as 86 million people. The study in Nature used direct satellite observa
Scientists are developing new fish vaccines using nanocellulose produced from Maine's wood pulp industry. Nanocellulose poses no known harmful effects to fish tissue and is unlikely to cause cellular damage. Fish vaccines made with nanocellulose may also be more effective and less expensive to produce than current vaccines made with adjuvants that are water and oil based, according to researchers.
Giving good feedback is an art. It can be challenging for supervisors and managers, whether in an educational setting or any other workplace. Our newly published review of the past decade's research on this issue confirms the key elements of improving feedback are to make it meaningful, constructive, timely and regular.
On Aug. 9, the U.N. released a dire climate report, the first since 2018, that warned of accelerated warming of the planet and splashed code red alert headlines across the world. To bring the Earth back from the brink will demand powerful collective action, the authors of the report wrote. But while the urgency of the message is growing in the public sphere, scientists, journalists, artists and cr
Good financial statement audits are essential to protect investors, and skeptical auditors are essential to good audits. A recent study finds that skepticism is being discouraged in auditors—and that there are unexpected challenges and opportunities for fostering skepticism in auditors moving forward.
The new report by the Intergovernmental Panel on Climate Change paints a sobering picture of the warming climate in coming decades. Among the projections is an increase in fire weather, which will expose Earth's landscapes to more large and intense megafires.
I have been covering research into fusion power for years , so I like to give updates when a significant advance is made. A recent announcement from the National Ignition Facility warrants such coverage. Fusion is the process of combing light elements into heavier elements. It's the process that fuels all suns, beginning by fusing hydrogen into helium. Protons of hydrogen are positively charged,

Nature Communications, Published online: 19 August 2021; doi:10.1038/s41467-021-25268-1 Synthesizing complex structures of high enantiomeric excess from racemic feedstock is an enduring challenge. Here, the authors couple racemic secondary alcohols with pyrroles to form enantioenriched 2-substituted heteroarenes, via a borrowing hydrogen mechanism using the combination of an iridium catalyst and
Nature Communications, Published online: 19 August 2021; doi:10.1038/s41467-021-25314-y Tetrel bonds are noncovalent interactions between electron donors and group 14 elements; in these situations, C(sp3) atoms can act as Lewis acids, accepting electron density. Here, the authors show that methyl groups, when bound to atoms less electronegative than carbon, can participate in noncovalent interact
Nature Communications, Published online: 19 August 2021; doi:10.1038/s41467-021-25352-6 It has long been hypothesized that certain emotional states are universally expressed with specific facial movements. Here the authors provide evidence that facial expressions of those emotional states are, in fact, varied among individuals rather than stereotyped.
Nature Communications, Published online: 19 August 2021; doi:10.1038/s41467-021-25305-z The authors create synthetic dimensions in acoustic crystals composed of cavity arrays, strongly coupled through modulated channels. They provide evidence for 1D and 2D dynamic topological pumping, and show that the higher-order topological sound transport is robust against the geometrical imperfections.
Nature Communications, Published online: 19 August 2021; doi:10.1038/s41467-021-25272-5 Sumoylation is important for the assembly and function of the SMN complex, which plays a central role in RNA processing.

Nature Communications, Published online: 19 August 2021; doi:10.1038/s41467-021-25249-4 The mechanisms by which in vivo expression of the Yamanaka transcription factors (OSKM) renders somatic cells permissive for differentiation remain unclear. Here, the authors show that in vivo reprogramming using OSKM generates germ cell tumors and drives acquisition of totipotency-like features in somatic cel
Blommor är livsviktiga för bin. Men det går lika bra med träd, visar en studie. Och helst pollen från en ek om biet själv får välja. Medvetenheten o m att pollinerande insekter behöver blommor rika på pollen och nektar ökar. I en ny studie visar det sig att träd kan vara minst lika viktiga för överlevnaden, som blommor åtminstone för det röda murarbiet, men troligtvis även för andra vildbin. Ett
Ma Mingliang rarely encountered wild elephants while growing up in southwestern China, after centuries of hunting and deforestation nearly eradicated them. Today, the 42-year-old village chief barricades his community to keep them out.

On March 11, 2021, the auction house Christie's sold a work by an American graphic designer, Michael Winkelmann, a.k.a. Beeple, for a colossal $69 million, making it the third most expensive work ever sold by a living artist. The work, Everydays: The First 5000 Days , is a nonfungible token, or NFT. It's a computer file that cannot be exchanged, copied, or destroyed, which gives the purchaser pro
Humans have always strived to develop technologies that give us some control, or at least the feelings of control, over the challenges that life throws at us. Psychologists like me devote our professional lives to figuring out why people think and feel what they do, and, in cases where those thoughts or actions are undesirable, to helping people change. We conduct experiments to see whether a cer
When I was about 6, my mind did something wondrous, although it felt perfectly natural at the time. When I encountered the name of any day of the week, I automatically associated it with a color or a pattern, always the same one, as if the word embodied the shade. Sunday was dark maroon, Wednesday a sunshiny golden yellow, and Friday a deep green. Saturday was interestingly different. That day ev
Engineers have devised a new approach to using sound waves to conduct complex manipulations of tiny particles suspended in liquid. Dubbed a 'shadow waveguide,' the technique uses only two sound sources to create a tightly confined, spatially complex acoustic field inside a chamber without requiring any interior structure. The technology offers acoustic tweezers abilities with applications in field
As wildfire fronts advance through landscapes or communities on the ground, they also attack from above, launching volleys of glowing embers into the air. Also known as firebrands, these specks of burning debris can glide for up to 40 kilometers (approximately 24 miles) before landing and can cause up to 90% of home and business fires during wildfires.
Whether a robot or a person delivers your package, the carbon footprint would essentially be the same, according to a new study that could help inform the future of automated delivery as the pandemic fuels a dramatic rise in online shopping.
An international study has found evidence of a long-sought effect in accelerator data. The so-called 'triangle singularity' describes how particles can change their identities by exchanging quarks, thereby mimicking a new particle. The mechanism also provides new insights into a mystery that has long puzzled particle physicists: Protons, neutrons and many other particles are much heavier than one
Mathematical research is aiding in the analysis of fMRI data. fMRI is the preeminent class of signals collected from the brain in vivo and is irreplaceable in the study of brain dysfunction in many medical fields, including psychiatry, neurology and pediatrics.
A new long-term study finds that male acorn woodpeckers breeding polygamously in duos or trios of males actually fathered more offspring than males breeding alone with a single female, contrary to conventional thinking among biologists that monogamous males necessarily produce more offspring than those in polygamous groups. For females, polygamy is less of a slam dunk but co-breeding duos left beh
A team of scientists has discovered chemical systems that self-assemble into molecular capsules which are highly toxic towards human cancer cells of a range of different tumor types, and which have demonstrated unprecedented cancer selectivity in the laboratory that in some cases are many thousands of times more toxic to the cancer cells compared to healthy, normal cells.
A previously healthy infant who suffered aborted sudden cardiac death was found to have a de novo genetic mutation in the SOS1 gene. Such mutations are typical of Noonan syndrome and suggests the syndrome may be a cause of unrecognized sudden death in infancy.
To fully harness the potential of sunlight, scientists have been trying to maximize the amount of energy that can be extracted from the sun. Researchers now describe how pairing metal halide perovskites with conventional silicon leads to a more powerful solar cell that overcomes the 26% practical efficiency limit of using silicon cells alone. Perovskites fulfill all the optoelectronic requirements
Prediction models based on clinical characteristics and imaging findings may help reduce the false-positive rate in women with dense breasts who undergo supplemental breast cancer screening with MRI, according to a new study.
Nature, Published online: 18 August 2021; doi:10.1038/d41586-021-02260-9 Dramatic antibody production in people infected during the 2002–04 outbreak furthers hopes of a vaccine against many coronaviruses.
A major crisis that accompanied the rise of the pandemic was lack of availability of the nasopharyngeal swab — necessary for testing for COVID-19, which in turn, was necessary to get a grip on the pandemic. An account of how one group addressed that crisis is published this week Journal of Clinical Microbiology, a journal of the American Society for Microbiology.
Giant anteaters living in less forested habitats make use of larger home ranges, according to a new study. This behavior may allow them to incorporate forest patches into their territory, the authors say.
Video images capture for the first time in live animals the inexorable spread of the COVID-19 virus, tracking the infection as it moved from the noses of mice to the lungs and other organs over the course of six days, in a new study.
Triple-negative breast cancer cells exposed to the antibody-drug conjugate sacituzumab govitecan may develop resistance to this powerful drug through alterations in both the target of the antibody and the target of the toxic payload. The findings illustrate how uncovering such mechanisms will critically inform strategies to overcome resistance to sacituzumab govitecan.

Due to their protected status, sea otter populations have rebounded across the Pacific Northwest Coast following their near elimination during the historic maritime fur trade. But the recovery of these shellfish predators and the federal laws now protecting them challenge local Indigenous communities who hold constitutionally protected rights to harvest those same shellfish but who are legally una
Strategies that not only conform to science but also consider the cultural context of countries are key to fighting future pandemics, according to researchers from Simon Fraser University and two U.S. universities.
Believe it nor not, more and more lending companies are turning to human-robot interaction to help with investment advice. But how do people react and what's the result of an investment decision when robots use algorithms to make suggestions? New research in the INFORMS journal Information Systems Research finds that investors who could benefit most from robo-advisors (RAs) aren't using them. And
The lack of adequate access to effective soil fertility testing in India, and much of the subtropical and tropical world, has led a group of scientists to explore how a smartphone camera might be transformed into a powerful and readily available alternative. Recently published in the Elsevier journal Biosystems Engineering, the research team describes important advances in the area of image-based
Management of many of the largest fisheries in the world assumes incorrectly that many small fish reproduce as well as fewer large ones with similar total masses, a new analysis has found. That can lead to overharvesting the largest, most prolific fish that can contribute the most to the population.
