Updated at 12:00 p.m. on December 16, 2021 America was not prepared for COVID-19 when it arrived . It was not prepared for last winter's surge. It was not prepared for Delta's arrival in the summer or its current winter assault. More than 1,000 Americans are still dying of COVID every day, and more have died this year than last. Hospitalizations are rising in 42 states. The University of Nebraska
New evidence from the bottom of a lake in the remote North Atlantic Faroe Islands indicates that an unknown band of humans settled there around 500 AD—some 350 years before the Vikings, who up until recently have been thought to have been the first human inhabitants. The settlers may have been Celts who crossed rough, unexplored seas from what are now Scotland or Ireland. The findings appear today
Touching the Sun NASA's Parker Solar Probe made history by becoming the first spacecraft to have "touched the Sun " earlier this year, the agency has now confirmed. The tiny probe made its way through the star's upper atmosphere, taking important readings of its surroundings. It even took the time to capture tons of images during its amazing stunt, which scientists stitched together for an incred
Astronomers from the Pennsylvania State University (Penn State) and elsewhere have detected a massive brown dwarf orbiting an M dwarf known as TOI-2119. The newly found object is nearly 70 times more massive than Jupiter and orbits its host star on an eccentric orbit. The finding is reported in a paper published December 7 on arXiv.org.
University of Cincinnati researchers have developed a sensor that detects toxins from algal blooms that taint surface water such as rivers, lakes and streams. Early detection of these toxins can aid water treatment plants to adjust the treatment strategy to keep the dangerous substances from contaminating drinking water.

Fan Service When tweeting in response to an adoring fanboy, Tesla and SpaceX CEO Elon Musk accidentally made the case for canceling student loan debt. "I came to the US with no money and graduated with over $100k in debt, despite scholarships and working 2 jobs while at school," Musk wrote . Rags to Rockets Naturally, this narrative serves Musk's up-by-his-cyber-bootstraps narrative, and as such,
Going Haywire Cryptocurrency prices went completely haywire on several crypto exchanges on Tuesday, spiking to ludicrous new heights.

I n January 1972 , when I was a 13-year-old boy in Dublin, my father came home from work and told us to prepare for civil war. He was not a bloodthirsty zealot, nor was he given to hysterical outbursts. He was calm and rueful, but also grimly certain: Civil war was coming to Ireland, whether we wanted it or not. He and my brother, who was 16, and I, when I got older, would all be up in Northern I

Remember IBM's Watson, the AI Jeopardy! champion? A 2010 promotion proclaimed, "Watson understands natural language with all its ambiguity and complexity." However, as we saw when Watson subsequently failed spectacularly in its quest to "revolutionize medicine with artificial intelligence," a veneer of linguistic facility is not the same as actually comprehending human language.

Last week, Meta (the umbrella company formerly known as Facebook) opened up access to its virtual-reality social media platform, Horizon Worlds. Early descriptions of the platform make it seem fun and wholesome, drawing comparisons to Minecraft. In Horizon Worlds, up to 20 avatars can get together at a time to explore, hang out, and build within the virtual space. But not everything has been warm
Into the Volcano In Red Bull-sponsored stunt news, a daredevil wingsuit pilot became the first person to fly in and back out of an active volcano, CNN reports . The best part about the story?

Facing the Fear The pilot, Chilean daredevil Sebastián Álvarez, plunged towards the Villarrica vo
Hurricanes in Iowa A series of record breaking, hurricane-force storms blew across the Midwest on Wednesday, destroying homes, toppling trucks, and causing sweeping power outages — and experts say climate change is a driving factor. The storms generated almost 20 tornadoes across Iowa, Minnesota, and Nebraska, CNN reports . One twister that hit southeastern Minnesota was even the first ever repor
The COVID-19 pandemic is not done with us yet. We are still in the middle of the delta surge, and while delta will eventually pass, the omicron variant is right on its heels. In the US we just passed the milestone of 800,000 people dead from COVID with over 50 million cases. More Americans died of COVID in 2021 than in 2020, although in 2021 most deaths were among the unvaccinated. The vaccines r

The next generation of superconducting magnets has the potential to revolutionize fields such as energy storage, particle accelerators and medicine. The magic behind these tools lies in the high-temperature superconducting (HTS) wires that power them.
According to right-wing media figures, the January 6 sacking of the Capitol that disrupted the counting of the 2020 electoral votes was " a false-flag operation ." It was just "politicians" having their "jobs disrupted for two hours." It was " mostly peaceful ." It was a " setup ," or perhaps it was the work of " antifa ," but those who were arrested and prosecuted are definitely " political pris

Greek mythology tells us that not long after a young and incautious Persephone was first taken into the underworld by Hades, she made a gaffe of epic proportions by sampling the cuisine. Down in the dirt, she munched on a pomegranate, binding herself eternally to a subterranean life. In this way, Persephone is basically a millipede. Bear with me. Millipedes' primary goal in life (other than repro
Seven years ago, I did a poetry reading at New Roads School, in Santa Monica, California. The students were incredible. They were funny, they were incredibly smart, and they asked the sorts of questions I had not been asked before. But one student stood out in particular. She was ebullient and curious and thoughtful. One of her teachers shared with me that she had recently been named the Los Ange
The wind finally blew the other way last night and kicked out the smoke from the burning Sierra. Down here in the flatland of California, we used to regard the granite mountain as a place apart, our getaway. But the distance is no more. With all those dead pine trees in thrall to wildfire, the Sierra, transmuted into ash, is right outside our door. We have learned to watch the sky with an uncanny

For 20 months, I was haunted by two fears: that some things (the pandemic, isolation, anxiety) would last forever, and that others (dreams, loved ones, entire years) would be lost forever. Time warped around me, as it did for so many people. Some days, it moved like molasses. On others, like when I saw family and friends, it seemed to flow like a river that I couldn't stop or outrun. Then, for tw
Unlike our Sun, most stars live with a companion. Sometimes, two come so close that one engulfs the other—with far-reaching consequences. When a team of astronomers led by Chalmers University of Technology, Sweden, used the telescope Alma to study 15 unusual stars, they were surprised to find that they all recently underwent this phase. The discovery promises new insight on the sky's most dramatic
Pyroclastic surges are lethal hazards from volcanoes that exhibit enormous destructiveness through large dynamic pressures of 100–102 kilopascal inside flows that are capable of obliterating reinforced buildings. These hot, fast and turbulent gas-and-ash clouds create far greater devastation to life and infrastructure than can currently be explained scientifically. But why are they so destructive?

Since the 1950s, efforts to ease traffic congestion have often contributed to urban decline. Instead of pouring money into new and wider roads in the hope of speeding our commutes, we should build places where people want to slow down and get out of their cars — places worth waiting in traffic to get to.
Rising house prices may change the personality make-up of US cities within a few years, with residents becoming increasingly open-minded—not just as wealthier people move in, but also among longer-term locals.

Yet, the detailed mechanics underlying these processes and the conditions leading to different rupture behaviors are not well understood. Here, we use a laboratory earthquake setup, capable of injecting pressurized fluids,…
When host cells are in low abundance, temperate bacteriophages opt for dormant (lysogenic) infection. Phage lambda implements this strategy by increasing the frequency of lysogeny at higher multiplicity of infection (MOI). However, it remains unclear how the phage reliably counts infecting viral genomes even as their intracellular number increases because…
Spina bifida (SB) is a debilitating birth defect caused by multiple gene and environment interactions. Though SB shows non-Mendelian inheritance, genetic factors contribute to an estimated 70% of cases. Nevertheless, identifying human mutations conferring SB risk is challenging due to its relative rarity, genetic heterogeneity, incomplete penetrance, and environmental influences…
Therapy resistance is responsible for most cancer-related death and is mediated by the unique ability of cancer cells to leverage metabolic conditions, signaling molecules, redox status, and other pathways for their survival. Interestingly, many cancer survival pathways are susceptible to disturbances in cellular reactive oxygen species (ROS) and may therefore…
The surge of post-truth political argumentation suggests that we are living in a special historical period when it comes to the balance between emotion and reasoning.

Microtubules are dynamic cytoskeletal polymers that spontaneously switch between phases of growth and shrinkage. The probability of transitioning from growth to shrinkage, termed catastrophe, increases with microtubule age, but the underlying mechanisms are poorly understood. Here, we set out to test whether microtubule lattice defects formed during polymerization can affect…
G protein-coupled receptors (GPCRs) are the largest family of human proteins. They have a common structure and, signaling through a much smaller set of G proteins, arrestins, and effectors, activate downstream pathways that often modulate hallmark mechanisms of cancer. Because there are many more GPCRs than effectors, mutations in different…
Mechanical properties are fundamental to structural materials, where dislocations play a decisive role in describing their mechanical behavior. Although the high-yield stresses of multiprincipal element alloys (MPEAs) have received extensive attention in the last decade, the relation between their mechanistic origins remains elusive.

Since the first sequencing of the human genome more than 20 years ago, the study of human genomes has relied almost exclusively on a single reference genome to which others are compared to identify genetic variations. Scientists have long recognized that a single reference genome cannot represent human diversity and that using it introduces a pervasive bias into these studies. Now, they finally ha
To paint a clearer picture of how global climate change will affect Earth's ecosystems, a team of 80 international research scientists set out to complete an unparalleled experiment: forcing the world's only enclosed rainforest—housed in the University of Arizona's Biosphere 2—through a four-month-long controlled drought and recovery.
Data from NASA's Parker Solar Probe bolster theories about one of the sun's greatest mysteries: why its outer atmosphere is hotter than its fiery surface. Two years ago , researchers predicted when the probe would pass a constantly moving, invisible barrier in the sun's upper atmosphere called the Alfven point. They also anticipated a strange phenomenon beyond that point, which heats elements to

Findings published to Frontiers in Marine Science showed that the archipelago—heavily reliant on tourism—could lose most of its beaches.
In our digital age, companies need more than just a digital footprint to get ahead of the game. Increasingly, many companies—both large and small, established or start-ups—are implementing digital strategies. In implementing a digital strategy, the top management's vision, and direction matter, but those, who participate in the implementation of the strategy, are crucial—that is, all employees.
Periods of record low snow levels over the past decade have increased the urgency of snow research. As snow studies expand, usage of the term "snow drought" to describe seasons of abnormally low snowpack has become common. But disagreements still exist over how to measure snow depth and how to define snow drought.
Researchers at the RIKEN Center for Sustainable Resource Science (CSRS) in Japan have recently created a healthier form of starch in the cassava plant. Published in the scientific journal Plant Molecular Biology, the study shows how reducing levels of starch branching enzymes (SBEs) in cassava plants changes the composition of tapioca starch, making it more resistant to digestion and healthier for
Søren Pind plæderer i Berlingske for, at vi herhjemme bør kigge mod syd for at få et mere effektivt sundhedsvæsen. Pinds betragtninger indeholder imidlertid faktuelle fejl og uunderbyggede påstande, der ikke bør stå uimodsagte, skriver læge og sundhedsøkonom René Flamsholt Christensen.

Loneliness levels rose during the lockdowns, but since restrictions have eased, people have not rushed out to find a new date. This has been given a name, "hesidating", and is defined as feeling indifferent or ambivalent about dating, being unsure whether you want to date seriously or casually, or even if you want to date at all.
A new fossil skeleton of an extinct species of bird from northeastern China that lived alongside dinosaurs 120 million years ago unexpectedly preserves a bony tongue that is nearly as long as its head.
A new study shows it's possible to transfer the brain benefits marathon-running mice enjoy to their couch-potato peers. The new research shows that blood from young adult mice that get lots of exercise benefits the brains of same-aged, sedentary mice. A single protein in the blood of exercising mice seems largely responsible for the benefit. The discovery could open the door to treatments that—by
Faculty at Iowa State University's College of Veterinary Medicine are laying the groundwork to teach students swine-medicine skills using virtual telehealth technology, a method that could reinforce biosecurity while allowing students to see more cases than they would using traditional approaches to teaching veterinary skills.
A simplified mathematical model of carbon dioxide (CO2) concentrations and temperature found a "lag time" between human intervention and an actual decrease in CO2 levels. This lag time has ramifications for intervention strategies meant to avoid climate tipping points and potentially catastrophic temperature increases.
People whose moral beliefs and values align closely with other members of their online communities—including those on social networks Gab and Reddit—are more prone to radicalization, according to new USC research.
Use of assisted reproductive techniques (ART) does not lead to poorer mental health in children across adolescence and young adulthood, according to a large observational study. The study found a slightly higher risk of obsessive-compulsive disorder for those born after ART but this was explained by parental background factors.

For more than 100 years, Albert Einstein's general theory of relativity has been our best description of how the force of gravity acts throughout the universe. General relativity is not only very accurate, but ask any astrophysicist about the theory and they'll probably also describe it as "beautiful." But it has a dark side too: a fundamental conflict with our other great physical theory, quantu
Tritium 3H, a radioactive isotope of hydrogen, is commonly used in medicinal chemistry as a label to follow the course of a drug in the human body. Chemists like to use the technique to evaluate drug candidates and their metabolism. A team led of researchers at the Max-Planck-Institut für Kohlenforschung in Mühlheim, Germany, has now found a new way to label complex small molecules with tritium. I
When it comes to raising children, men and women have different perspectives on the division of household labor—from cooking meals to offering emotional support—according to a new poll from the Associated Press-NORC Center for Public Affairs Research and the Harris School of Public Policy at the University of Chicago.
In an astonishing feat of endurance, explorers Justin Packshaw and Jamie Facer Childs are a quarter of the way through a 3600-km kitesurf trek that takes them across the desolate heart of Antarctica. They are not pushing their physical and mental limits to the brink, facing howling gales and temperatures of –55°C just for the sake of adventure.

Driving and walking rovers competed to survey a shadowy analog of the south polar lunar surface for useable resources during the inaugural ESA-ESRIC Space Resources Challenge. Some 13 teams from across Europe and Canada took part in last month's field test, with the winners due to be announced shortly.
Researchers have uncovered a surprising new explanation for why pedestrian bridges can suddenly start to wobble and sway: too many people crossing at once and simply trying not to fall over. In a new study published in the journal Nature Communications , researchers show how a bridge—even one as highly engineered as the Golden Gate or the Brooklyn Bridge—can become suddenly unstable. If enough pe
A team of researchers from the University of Malta and the European Synchrotron Radiation Facility in France has developed a new segmentation method for viewing the inside of mummified remains. In their paper posted on the open access site PLOS ONE, the group describes their new technique and how well it worked when tested on mummified animals.
From high-profile wildfires in the American West over the last several years, to visibly cleaner air during pandemic slowdowns, air quality is returning to the forefront of environmental concern.

Our oceans are under pressure like never before, with over 60% struggling from the increasing impact of fishing, coastal activities and climate change. The harsh truth is that as we move towards 2022 only 3% of oceans are totally free from the pressure of human activity. The greatest impact appears to be on large-bodied animals such as marine mammals and birds, which cannot reproduce as quickly as
On March 6, 2020, universities across the U.S. announced systematic laboratory closures, social distancing policies and travel bans to cope with the growing coronavirus epidemic. These actions, while prudent and necessary, had immediate negative impacts on the academic enterprise of science in the U.S. and around the world.
A team of researchers from Skoltech and their Russian and U.S. colleagues have gathered two dozen mushrooms of the species Schizophyllum commune and analyzed their DNA, gaining insights into mutations that cancel the negative effects of other mutations. This phenomenon applies to all organisms but is way more prominent in the extremely genetically variable mushroom than in humans. The mutation int

More than 100 unpublished drawings by the German writer Franz Kafka are now available in a new book. Most people know Franz Kafka for his written works such as The Metamorphosis , The Trial , and The Castle , yet he also drew vigorously. Until recently, only 40 of Kafka's drawings had come to light. When in 2019 a safe deposit box from a vault on Zurich's Bahnhofstrasse was opened after years of
Social media was used to both spread misinformation and for fact-checking during the height of the COVID-19 pandemic, according to a new study which explores how individuals perceive and make sense of information they encounter during times of global crisis.
We can't understand polarization unless we analyze it as a complex system, argue SFI External Professor Scott Page (University of Michigan) and co-author Delia Baldassarri in a commentary for a special feature on the dynamics of political polarization in the Proceedings of the National Academy of Sciences.
Within complex tissues such as cancer tumors, individual cells can vary widely from each other. Internally, cancer cells can develop unique DNA mutations and genomic changes, potentially leading to drug resistance, metastasis, or relapse. Externally, the cells' specific locations within the tissue also matter, since the local structure of a tumor and its surrounding tissues can affect cell state a
Polarization is dangerous for democracy. Though the U.S. Constitution was designed to harness rivalry with a diverse, redundant, and modular set of institutions, if that rivalry curdles into the belief that your competitors are your enemies, those institutions may not be strong enough to hold a nation together.

Well into the 1980s, doctors would perform open-heart surgery on infants without giving them pain-relieving drugs. This is hard to believe: By the standards of contemporary medicine, not to mention common sense, the practice is akin to torture. Yet then-conventional wisdom held that babies did not feel pain, at least not in any meaningful way. Their brains and nervous systems were considered unde
Ten thousand years ago, a mother clutched her growing belly. A month earlier, the pregnancy had become difficult—something was wrong. The mother's stress was the baby's stress too, and the baby was due to be born in a few weeks. The mother rested by the Neva River as it flowed down the mountains on its way to the sea. She lived in the Ligurian region of northwest Italy. People in her community we
A god who knows everything, is everywhere, and wields impossible power, is a potent fantasy. Allegiance to it animates the lives of billions worldwide. But this "Big God," as psychologists and anthropologists refer to it, wasn't dreamt from scratch but pieced together, over thousands of years, paralleling humanity's move from small- to large-scale societies. One burning question researchers want
Hospitals rely on donated blood for a range of treatments, and the pandemic has seriously threatened that supply. Here's what you need to know about the science behind blood donation — and why it's critically needed.
