For decades, humans have been selectively breeding cats and dogs to exhibit exaggerated features—particularly in their faces. When it comes to cats, the very flat, round faces of the modern Persian and Exotic Shorthair are classic examples. These breeds are likely a result of humans' preference for infant-like features that may directly tap in to our nurturing instincts.
An international team of analysts reports evidence that suggests it is not likely that the peer review process is to blame for gender publishing inequalities in scholarly journals. In their paper published in the journal Science Advances, the group describes their study of the peer review process for 145 scholarly journals to determine if there were gender biases and what they found.
Scientists have used computer modeling to identify potential 'vulnerable sites' on a key protein found in coronavirus—paving the way for possible new drug treatments in the future.

Before researchers can smash together beams of particles to study high-energy particle interactions, they need to create those beams in particle accelerators. And the tighter the particles are packed in the beams, the better scientists' chances of spotting rare physics phenomena.
Normally the word "chaos" evokes a lack of order: a hectic day, a teenager's bedroom, tax season. And the physical understanding of chaos is not far off. It's something that is extremely difficult to predict, like the weather. Chaos allows a small blip (the flutter of a butterfly wing) to grow into a big consequence (a typhoon halfway across the world), which explains why weather forecasts more th

The harbor porpoise population is declining in the German North Sea, according to a recent study which surveyed the species over a 20-year time period. Harbor porpoises are known as a "sentinel species" – animals which indicate the health of an ecosystem and point to potential risks (think of the canary in the coal mine) – and their decreasing numbers indicate the extent to which human activities
The North Sea is a heavily trafficked area, with major shipping routes crossing its waters, and fisheries, offshore oil rigs, and wind farms populating its waves. All this activity inevitably has an effect on marine wildlife, and scientists are particularly interested in how the harbor porpoise population has fared in the face of such disturbances.

Insurrection Day, 12:40 p.m.: A group of about 80 lumpen Trumpists were gathered outside the Commerce Department, near the White House. They organized themselves in a large circle, and stared at a boombox rigged to a megaphone.

In 1991 two hikers in the Italian Alps stumbled on a mummified body buried in the ice. The Iceman, it turned out, died more than 5,000 years ago. At first, archeologists assumed he'd fallen in a snowstorm and frozen to death. Then they discovered various cuts and bruises on his body and an arrowhead embedded in his shoulder. They also found traces of blood on the stone knife he was carrying. Most
When a Weddell seal, native to Antarctica, plummets 400 meters beneath the ice on one of its hour-long dives, an ensemble of adaptations come together to keep it alive. The seal's heart rate slows. At this pace, it will burn through its deep reserve of oxygen—provided by extra-large volumes of blood and hemoglobin—more slowly. The seal's muscles free massive stores of trapped oxygen from another
Humans once lived in harmony with the natural world. Consider timekeeping. Until relatively recently, the human notion of time was based on the natural rhythms of nature. Time was measured by a new moon, the first snow, a migrating bird, or the ebb and flow of a river. Time meant situating ourselves as part of a larger web of life. Western society has since lost its connection to nature. Human-cr
As a mob of right-wing extremists occupied the US Capitol building on Tuesday, President Trump posted a short video message to his loyal supporters on social media: "We had an election that was stolen from us," he said, repeating a lie he has promoted for months.

The Ellipse was a deep sea of delusion. Thousands of President Donald Trump's supporters drove or bused or flew from all corners of the United States to meet here, in the treeless space beside the White House, in their quest to overturn the results of the 2020 election with the help of congressional Republicans. "As I live and die, we will never give up until we have a fair-and-square election!"
Working with mice, researchers have identified an immune system cell that they say travels from the gut to the brain and attacks cells rather than protect them as it normally does.
This afternoon, a mob of pro-Trump extremists stormed the Capitol, where Congress had convened to certify Joe Biden's victory in the 2020 election.

Trump's Coup Hundreds of Trump supporters stormed the Capitol building in Washington, DC today, breaking windows and stealing property. Egging them on, as recently as earlier today, has been President Donald Trump himself, who has refused to concede the election even in the face of overwhelming evidence that he lost to challenger Joe Biden. "Our country has had enough." Trump told a crowd today.
Covid-19 patients who recovered from the disease still have robust immunity from the coronavirus eight months after infection, according to a new study. The result is an encouraging sign that the authors interpret to mean immunity to the virus probably lasts for many years, and it should alleviate fears that the covid-19 vaccine would require repeated booster shots to protect against the disease
Thousands of people received convalescent plasma as an experimental treatment for Covid. A new study shows that it works — but only when given within a few days of the onset of illness.
The Sloan Kettering researcher used mutagenic screening to probe genes and molecular pathways, including Toll and Hedgehog, essential to development in fruit flies and mice.

Eye Contact A powerful new facial recognition system can recognize and identify people 96 percent of the time — even when they're wearing a mask to protect against the coronavirus. When the pandemic really took hold, it became clear that the facial recognition systems already on the market weren't up to the challenge of identifying people who covered the bottom half of their head with a face mask
Remote working is not only a different way of working but also a different way of living. Remote life style could be the future of our work and life. It is predicted that 38% of full-time workers will work remotely in the next decade, and remote work has increased by 115% since 2005. According to a report by the International Remote Work Association, the demand for remote work will increase by 30
Before the pandemic, one-third of U.S. households with children were already "net worth poor," lacking enough financial resources to sustain their families for three months at a poverty level, finds new research from Duke University.
Starting as a single cell, organisms undergo millions of generations of divisions to ultimately generate the bones, heart, brain and other components that make up a living being. The mainspring within this intricate process is the transfer of DNA through each subsequent cell split within discrete packets called chromosomes.
They are as thin as a hair, only a hundred thousand times thinner—so-called two-dimensional materials, consisting of a single layer of atoms, have been booming in research for years. They became known to a wider audience when two Russian-British scientists were awarded the Nobel Prize in Physics in 2010 for the discovery of graphene, a building block of graphite. The special feature of such materi

Before the pandemic, one-third of U.S. households with children were already "net worth poor," lacking enough financial resources to sustain their families for three months at a poverty level, finds new research from Duke University. In 2019, 57 percent of Black families and 50 percent of Latino families with children were poor in terms of net worth. By comparison, the rate for White families was
Using Center for Disease Control's national population health and cancer statistics datasets, Rush University Medical Center researchers determined that a state's opioid death rate significantly predicted the trend in the incidence of pancreatic cancer years later. This is the first study showing opioid use may be a risk factor contributing to the increasing incidence of pancreatic cancer
For more than seven years, a mysterious wasting disease has nearly killed off sea star populations around the world. Some of these species stand at the brink of extinction.
The Earth is populated by an increasing number of people who demand more and more products, which is simply not viable in the long run. Our planet does not have unlimited resources. Emissions are harming the environment in various ways.
Using copper foil, glass containers and a conventional household microwave oven, University of Wyoming researchers have demonstrated that pulverized coal powder can be converted into higher-value nano-graphite.

The new year is going to be better. It has to be better. Maybe you're one of the 74% of Americans in one survey who said they planned on hitting the reset button on Jan. 1 and resolving to improve. Those New Year's resolutions most commonly focus on eating healthier, exercising, losing weight and being a better person. Admirable goals, to be sure. But focusing on body and mind neglects something
A team of researchers led by the Indiana Biosciences Research Institute Diabetes Center's Scientific Director Decio L. Eizirik, MD, PhD, has found that identifying new treatments for autoimmune diseases requires studying together the immune system AND target tissues. This study, "Gene expression signatures of target tissues in type 1 diabetes, lupus erythematosus, multiple sclerosis and rheumatoid
Working with mice, researchers at Johns Hopkins Medicine and the University of Lausanne in Switzerland have identified an immune system cell that they say travels from the gut to the brain and attacks cells rather than protect them as it normally does.
An Oxford scientist with a flair for the dramatic, he introduced millions of people to the secrets of their ancestry through his books and TV appearances.
A study led by University of Ottawa researchers provides empirical evidence that mindfulness has a significant impact on the brain of women suffering from neuropathic pain related to breast cancer treatment.

Spatially concentrating and manipulating biotherapeutic agents within the circulatory system is a longstanding challenge in medical applications due to the high velocity of blood flow, which greatly limits drug leakage and retention of the drug in the targeted region. To circumvent the disadvantages of current methods for systemic drug delivery,…
Genetic variants underlying life-threatening diseases, being unlikely to be transmitted to the next generation, are gradually and selectively eliminated from the population through negative selection. We study the determinants of this evolutionary process in human genes underlying monogenic diseases by comparing various negative selection scores and an integrative approach, CoNeS,…
Cisplatin is a mainstay of systemic therapy for a variety of cancers, such as lung cancer, head and neck cancer, and ovarian cancer. However, resistance to cisplatin represents one of the most significant barriers for patient outcome improvement. Actin-like 6A (ACTL6A) is a component of several chromatin remodeling complexes, including…
The current lack of a standardized nomenclature system for gene products (e.g., proteins) has resulted in a haphazard counterproductive system of labeling. Different names are often used for the same gene product; the same name is sometimes used for unrelated gene products. Such ambiguity causes not only potential harm to…
The two-dimensional electron gas (2DEG) realized in semiconductor heterostructures has been the focus of fruitful study for decades. It is, in many ways, the paradigmatic system in the field of highly correlated electrons. The list of discoveries that have emerged from such studies and have opened new fields of physics…
Roughly two billion years ago, microorganisms called cyanobacteria fundamentally transformed the globe. Researchers are now stepping back to that pivotal moment in Earth's history.
Drug-resistant bacteria could lead to more deaths than cancer by 2050, according to a report commissioned by the United Kingdom in 2014 and jointly supported by the U.K. government and the Wellcome Trust. In an effort to reduce the potential infection-caused 10 million deaths worldwide, Penn State researcher Scott Medina has developed a peptide, or small protein, that can target a specific pathoge
The study found that 'loading' a chemotherapy drug on to tiny magnetic particles that can heat up the cancer cells at the same time as delivering the drug to them was up to 34% more effective at destroying the cancer cells than the chemotherapy drug without added heat.
New research shows how X-Men villain Magneto's super powers could really work. Researchers have made the first observations of biological magnetoreception – live, unaltered cells responding to a magnetic field in real time. This discovery is a crucial step in understanding how animals from birds to butterflies navigate using Earth's magnetic field and addressing the question of whether weak electr
Updated on January 6 at 4:30 p.m. Insurrectionists are attacking the seat of American government in an attempted coup, urged on by the president of the United States. Saying that feels melodramatic, ridiculous, and overwrought, but there's no plainer way to describe what is currently unfolding. Tens of thousands of supporters of outgoing President Donald Trump gathered in Washington, D.C., where
Artificial intelligence has gotten very good at some things — it's even approaching the capability of people when it comes to recognizing objects and generating text. What about art? OpenAI has devised a new neural network called DALL-E (it's like Dali with a nod to beloved Pixar robot WALL-E). All you need to do is give DALL-E some instructions, and it can draw an image for you. Sometimes the re
Psychedelic Upload A team of scientists has an unusual plan for figuring out how psychedelic drugs affect our brains: giving virtual versions of the substances to neural network algorithms and watching what happens. The idea, PsyPost reports , is that by recreating the psychedelic hallucinations caused by DMT in a neural net modeled after the human brain, scientists may be able to better uncover
Taking advantage of the chemical properties of botulism toxins, two teams of researchers have fashioned non-toxic versions of these compounds that can deliver therapeutic antibodies to treat botulism, a potentially fatal disease with few approved treatments.
Curating a film preview for 2021 involves all the necessary caveats. Because the cinema industry remains deeply in flux and many theaters have yet to reopen, this year will likely be full of schedule changes and surprise decisions to move some projects to streaming. One major studio, Warner Bros., plans to debut each of its films simultaneously in theaters and on the streaming service HBO Max; ot
E. coli food poisoning is one of the worst food poisonings, causing bloody diarrhea and kidney damage. But all the carnage might be just an unintended side effect, report researchers. Their findings might lead to more effective treatments for this potentially deadly disease.
Often considered the world's oddest mammal, Australia's beaver-like, duck-billed platypus exhibits an array of bizarre characteristics: it lays eggs instead of giving birth to live babies, sweats milk, has venomous spurs and is even equipped with 10 sex chromosomes. Now, an international team of researchers has conducted a unique mapping of the platypus genome and found answers regarding the origi
The main bioactive compound of ginger root lowers autoantibody production and helps halt disease progression in mice with antiphospholipid syndrome and lupus.
Researchers found that so-called photonic processors, with which data is processed by means of light, can process information very much more rapidly and in parallel than electronic chips.
Conductive ink is a great tool for printing flexible electronic circuits on surfaces. But these inks can be costly, they do not work on some materials, and devices to apply them can plug up. Now, scientists report that they have developed inexpensive conductive inks for clog-free ballpoint pens that can allow users to 'write' circuits almost anywhere — even on human skin.
Researchers created an environment in a microwave oven to successfully convert raw coal powder into nano-graphite, which is used as a lubricant and in items ranging from fire extinguishers to lithium ion batteries.
Hoppy beers such as pale ales are becoming increasingly popular. One reason is their pleasant fruity aroma that partially stems from compounds called thiols. Brewers have been looking for an accurate way to track thiols in beer, but current methods typically are not sensitive enough or require use of potentially harmful substances. Now, researchers present an automated, solvent-less process to ass
New research suggests that starfish, victims of sea star wasting disease (SSWD), may actually be in respiratory distress – literally 'drowning' in their own environment – as elevated microbial activity derived from nearby organic matter and warm ocean temperatures rob the creatures of their ability to breathe.
A multidisciplinary team of researchers has discovered several genetic markers associated with bone mineral accrual, which could ultimately help identify causes of eventual osteoporosis earlier in life through genetic testing.
All athletes want to be at the top of their game when they compete, but some resort to nefarious approaches to achieve peak muscle growth, speed and agility. Recent developments in gene editing technology could tempt athletes to change their DNA to get an edge. Now, researchers demonstrate first steps toward detecting this type of doping both in human plasma and in live mice.
