Acclaimed musician Claire "Grimes" Boucher posted a TikTok video on Wednesday night in which she returned to one of her favorite pastimes: overpromising what artificial intelligence can provide to society. "I have a proposition for the communists," she said in the video . "Typically, most of the communists I know are not big fans of AI. But — if you think about it — AI is actually the fastest pat
Republicans say they would like to move on from the 2020 election. "A lot of our members, and I think this is true of a lot of House Republicans, want to be moving forward and not looking backward," John Thune, the third-ranking Republican in the Senate, told CNN on May 19. "Anything that gets us rehashing the 2020 elections I think is a day lost on being able to draw a contrast between us and th
For decades, anthropologists have been telling us that it's often the informal, unplanned interactions and rituals that matter most in any work environment. So how much are we missing by giving them up? In the summer of 2020, Daniel Beunza, a voluble Spanish social scientist who taught at Cass business school in London, organised a stream of video calls with a dozen senior bankers in the US and E
In the 1950s, four decades before he won a Nobel Prize for his contributions to game theory and his story inspired the book and film "A Beautiful Mind," the mathematician John Nash proved one of the most remarkable results in all of geometry. Among other features, it implied that you could crumple a sphere down to a ball of any size without ever creasing it. He made this possible by inventing a..
Researchers set out to learn how extreme winter cold and heat affected 41 common bird species in eastern North America. They found that individual bird species respond differently to these weather events, and extreme winter heat may lead to longer-term changes in bird populations.
High performance computers are central to the quest to understand the sun's behavior and its role in space weather events. With funding from NSF and NASA, scientists are using the Frontera supercomputer to improve the state-of-the-art in space weather forecasting. Writing in the Astrophysical Journal in April 2021, researchers described the role of backstreaming pickup ions in the acceleration of
Many data scientists try to create models that can "fit an elephant," referring to a complex set of data points. CSHL Professor Partha Mitra describes how he views problems like these in Nature Machine Intelligence. While the role of strong prior knowledge can work well in some situations, the complete absence of prior assumptions will work adequately in others. Mitra discusses a middle ground tha
On the occasion of the 50th anniversary of the National Academy of Medicine, Manson and co-author Cynthia Stuenkel, M.D., of the University of California San Diego's School of Medicine, wrote a Perspective piece for The New England Journal of Medicine chronicling major points of progress in women's health since the 1970s and expectations for the future.

Seismic waves generated by earthquakes travel through Earth's solid iron inner core faster in the direction of the rotation axis than along the equator. Scientists created a core growth model to explain this. To fit seismic data, the model predicts that asymmetric growth of the core leads to crystal movement that preferentially aligns iron-nickel crystals north-south. The model implies that the co
New research into Alzheimer's disease (AD) suggests that secondary infections and new inflammatory events amplify the brain's immune response and affect memory in mice and in humans — even when these secondary events occur outside the brain.
A new study reveals that beetles, wasps and other beneficial arthropods are nearly twice as abundant and diverse in uncultivated field edges in the spring as they are in areas that are cropped – if those field edges are rich in an array of flowers and other broad-leaved plants and not just mowed grass.
With demand for single-family rentals at an all-time high, there has never been a better time to sell your rental property than right now. Unfortunately, a lot of investors are reluctant to strike while the iron is hot because the traditional process of selling real estate takes too long, costs too much money, and requires too much work. So instead of cashing out on a property and using the profi
The simplest questions are often the hardest to answer. At first blush, the sun and stars are very different. The former is close and hot, the latter far away and cold. We couldn't confirm the sun to be a star until telescopes and spectroscopes were invented. Sometimes, as a scientist, you forget how much you take for granted about the amazingness of the universe. The other day, my colleagues and
UNC School of Medicine researchers led by mucin expert Mehmet Kesimer, PhD, had previously discovered that the total mucin concentrations in the lungs are associated with COPD disease progression and could be used as diagnostic markers of chronic bronchitis, a hallmark condition for patients with COPD.

A year ago SpaceX made headlines after posting job openings for operations engineers. The task at hand? To help design and build an offshore rocket launch facility—aka, a floating spaceport. Between the job postings and Elon Musk's tweet that the spaceports were intended for launches to Mars, the moon, and hypersonic travel around Earth, the whole thing seemed somewhat outlandish. A year later, t
Just as your freezer keeps food from going bad, Arctic permafrost protects frozen organic material from decay. As the climate warms, however, previously frozen landscapes such as peatlands are beginning to thaw. But how much fresh carbon will be released into the atmosphere when peat leaves the deep freeze of permafrost?
For decades, researchers have debated whether the buildup of certain electrical activities in the brain indicates that human beings are unable to act out of free will. A new article argues that recent research undermines this case against free will.
Weather stations provide detailed records of temperature, precipitation, and storm events. These stations, however, are not always well spaced and can be scattered throughout cities or can even be absent in remote regions.

A study published in STEM CELLS Translational Medicine shows that patients with type 2 diabetes, who are not overweight and who have had the disorder for less than a decade, can benefit from stromal stem cells transplanted from their own bone marrow resulting in short-term reductions in their blood glucose levels.
The COVID-19 pandemic not only disrupted Australian sport, but accelerated long term trends that are fundamentally changing how sport is consumed, delivered and managed, suggest researchers of a new report from Swinburne University of Technology, Deakin University and sports thought leadership summit, SportNXT.
Theoretical material design and experimental synthesis have advanced in the past few decades with a key role in the development of functional materials, useful for next generation technologies. Ultimately, however, the goal of synthesis science remains to be achieved in order to locate atoms in a specific position of matter. In a new report now published on Science Advances, Changhee Sohn and rese
So much has been said and written about the COVID-19 pandemic. We've been flooded with metaphors, idioms, symbols, neologisms, memes and tweets. Some have referred to this deluge of words as an infodemic.
During the first year of the pandemic, it was wealthier countries, with their comparatively stronger health systems, civil services, legal systems and other public services, that suffered the highest rates of COVID-19. Indeed, countries rated to be best prepared to respond to public health threats such as pandemics—those with the greatest "global health security"—had the most COVID-related fatalit
High school students facing housing deprivation have double the rates of depression and suicide risk, according to a large-scale study based on the Youth2000 surveys co-led by Te Herenga Waka—Victoria University of Wellington and the University of Auckland.
NC State researchers are turning wood byproducts into sensory hydrogels that can react to different stimuli and, through advanced manufacturing methods, are made into sustainable, biodegradable smart materials that can be used in agriculture, health care and even veterinary medicine.
Some say age is only a number. Others associate age with wisdom. Or perhaps it is a state of mind. Whatever it is, age is a factor in climate progress, and 2021's renewed climate momentum must mobilize the oft-overlooked elderly demographic.
A new study used demographic data to explore current and projected population changes around the world. Europe and Asia are shrinking, while Africa is still growing. For the first time in history, people aged 65+ outnumber children younger than five. Underpopulation will cause serious challenges for sustainability. The 20th century saw the greatest population surge in human history, rising global
Lithium is a vital element in the batteries that power electric vehicles, but soaring lithium demand is expected to exhaust land-based reserves by 2080. KAUST researchers have now developed an economically viable system that can extract high-purity lithium from seawater.
The towns of Vent and Obergurgl are nestled in the Ötz Valley in the Tyrol region of Austria, just north of the Italian border. They sit on either end of the mountain valley, framed by jagged peaks and lush meadows. They appear quite similar, quintessentially picturesque mountain villages with chalets and steep roof peaks, but Vent and Obergurgl are in starkly different economic and social situati
Nuclear detonations unleash an astonishing amount of destructive force. But the extreme pressure and temperature that they generate also makes nuclear blasts a cauldron of chemical creation, capable of delivering new and surprising scientific discoveries.
Tampons and sanitary pads that have been modified to change colour in the presence of some urinary tract infections could help to quickly diagnose such conditions in countries where access to healthcare is limited
Miljøstyrelsen udstedte i juli 2019 en miljøtilladelse til Baltic Pipe-projektet, men tilladelsen er nu ophævet af Miljø- og Fødevareklagenævnet. Det vækker ærgrelse hos Energinet, som nu vil undersøge konsekvenserne for det ambitiøse projekt.

When the Falcon 9 rocket launches on June 3, it will be carrying thousands of pounds of cargo to the International Space Station aboard SpaceX's 22nd commercial resupply services mission. Yet the last five items to be loaded will weigh less than an ounce. These include two plant and two animal species along with a microbial study. Scientists will examine these to better understand how to prepare f
The seismic discontinuity that occurs at an average depth of 647-654 km, usually called the 660 km seismic discontinuity, is the boundary between the transition zone and the lower mantle. It is considered to be caused by the transformation of ringwoodite to bridgmanite and MgO (post-spinel transition).
Prof. Huang Qing's group from the Hefei Institutes of Physical Science (HFIPS) developed a surface-enhanced Raman spectroscopy (SERS) gas sensor to detect aldehyde with high sensitivity and selectivity, which provided a new detection method for studying the adsorption of gas molecules on porous materials. The relevant research results have been published in Analytical Chemistry.
Remember the bird flu? Avian influenza (H5N1) was first discovered in birds in 1996, with the first human crossover detected in 1997. Since then it has bee discovered in 50 countries and is endemic is six. If you are old enough to remember, there was a bit of a bird flu panic back in the late 90s. Fortunately, so far, those fears have not been realized. But it's important to remember that the bir
When Kevin Gruenberg's wife was pregnant, he was anxious, irritable, and preoccupied with the thought that his stomach was growing. He kept thinking of a family story, from when his mother was pregnant with him, and his father gained weight in parallel. In 2014, three decades later, Gruenberg was having a similar experience, though it went beyond overeating. And although he is a psychologist in L
I got my first COVID-19 vaccine recently. The whole experience was tremendously routine: I showed my registration, stood in a waiting area, saw a nurse, got the jab, waited 15 minutes in case of an adverse reaction, and left. Oh, and I got a button. The waiting period, of course, was when it happened. James , said the pestilential voice inside my head, while I was scrolling on my phone. James! Wh
A team of Leiden astronomers has managed to calculate the first 100 million years of the history of the Oort cloud in its entirety. Until now, only parts of the history had been studied separately. The cloud, with roughly 100 billion comet-like objects, forms an enormous shell at the edge of our solar system. The astronomers will soon publish their comprehensive simulation and its consequences in
Disease-causing bacteria like Escherichia coli O157:H7 and Salmonella enterica could survive sanitization in beef processing facilities. Scientists and collaborators in the United States Department of Agriculture's (USDA), Agricultural Research Center (ARS) are investigating how this happens while also seeking approaches to solve the problem.
Although Earth and Venus are similar in size and location, they are very different worlds today. While Earth has oceans of water and abundant life, Venus is dry and fiercely inhospitable. Although it's somewhat closer to the sun—about 70 percent of Earth's distance—Venus is much hotter, with temperatures at the surface high enough to melt lead. The scorched landscape is obscured by clouds of sulfu
White dwarfs, the glowing cores of dead stars, often host disks of dusty debris. However, these debris disks only appear 10 to 20 millions of years following the star's violent Red Giant phase. A new paper by Planetary Science Institute Research Scientist Jordan Steckloff unravels the reason for this delay.
A new study confirms that there are two separate species of threatened pygmy marmosets but finds they can't be distinguished by fur coloring, as was previously thought. The study also broadens the distribution range for both species to include Ecuador and Peru.
Researchers report a new method for controlling how artificial intelligence systems create images. At issue is a type of artificial intelligence (AI) task called conditional image generation, in which AI systems create images that meet a specific set of conditions. For example, a system could be trained to create original images of cats or dogs, depending on which animal the user requested. More
It wasn't so long ago that the internet was supposedly about to kill the book. Instead, we now use the internet, or at least machine learning, to recommend books, find deals on books, and even to write books . Still, if you're nervous about getting to that ever-growing library on your Kindle or in the corner of your bedroom, or need to be picky about what you spend your time on, a two-year subscr
The term bullying is now used so broadly that the phenomenon may seem pervasive well beyond adolescence. In Ben Smith's recent New York Times exposé of WNYC, the subhead notes, "In public radio, there's either an epidemic of bullying or an epidemic of whining, depending on whom you ask." Left unasked was a key question: Is workplace bullying, writ large, a genuine phenomenon? The term, traditiona
For critics who say that an audit of 2020 votes in Maricopa County, Arizona, is just a costly exercise in misinformation , the Republican state senators who ordered the count have a simple question: If you're sure that the votes were counted correctly, then what's the harm in counting them again to reassure voters who aren't convinced? "We are here to make sure Arizona voters can have faith and c

Here, the authors combine single-cell RNA imaging, antisense oligonucleotides and splicing analyses to show that retention of spec
Trädarter från Afrikas höglänta bergsregnskogar kan anpassa både fotosyntes och bladens ämnesomsättning till uppvärmning. Men skilda artgrupper är olika bra på detta. Livskraften och sammansättningen hos framtidens tropiska skogar beror på hur träden kan anpassa sina inre fysiologiska processer till ett allt varmare och, på många ställen, torrare klimat. Trädarter från Afrikas höglänta bergsregns
När människor tvingades stanna hemma på grund av coronapandemin minskade antalet inbrott, rån och mord. I Malmö och Stockholm var effekterna på brottsligheten minst av alla jämförda länder. De restriktioner som införts världen över i kampen mot covid-19 har lett till en dramatisk minskning av brottsligheten i storstäderna, visar en ny studie. Sverige och Malmö sticker dock ut med den mest blygsam

Just weeks after a major American oil pipeline was struck by hackers , a cyberattack hit the world's largest meat supplier. What next? Will these criminals target hospitals and schools? Will they start going after US cities, governments—and even the military? In fact, all of these have been hit by ransomware already. While the onslaught we've seen in the last month feels new, hackers holding serv
Due to strict COVID-19 isolation protocols, many Intensive Care Unit patients in Spain's hospitals have gone months without a visit from their family and friends. On average, patients spend up to three months hospitalized in the ICU and recovery—all without a single visitor.

When the University of Colorado at Denver completed an investigation in 2015 into the work of a former faculty member, the school recommended that nine papers be corrected or retracted. But six years after the close of that investigation, the researcher, urologist Hari Koul, has had just two papers retracted and one corrected. Multiple journal … Continue reading
Since the early 1950s, humans have produced more than 8.3 billion tonnes of plastic—the weight of around a billion elephants. About 60% of that plastic has ended up in a landfill or in the natural environment, according to the UN Environment Programme, but that pattern may start to change as repair and recycling technology gathers pace.
Det finns god kunskap om vad som ökar risken att drabbas av en första hjärtinfarkt – men mindre om vad som orsakar återkommande hjärt-kärlsjukdom.

The Trump administration missed an opportunity to strengthen the country's out-of-date standards for soil contaminants like lead, which will never go away without mitigation. Perhaps it's time to envision a Clean Soil Act that could protect soil ecosystems and the health of the people who live on them.
A few weeks ago, Michelle Watson woke up to a deafening, steadily oscillating screech. "What the heck is that noise?" she wondered. She went outside to her yard and saw hundreds of beady-eyed insects enrobed in a thick shell of gold emerging out of the ground and crawling up the trees. What Watson was seeing was the emergence of thousands of Brood X cicadas, part of a billions-strong insect swarm
Electric fish pause before sharing something particularly meaningful. Pauses also prime the sensory systems to receive new and important information, according to new research. American writer and humorist Mark Twain once offered, "The right word may be effective, but no word was ever as effective as a rightly timed pause." "There is an increased response in listeners to words—or in this case, el

Elaine Morgan had sass. In Descent of Woman , published in 1972, she asked her readers to take science into their own hands. "Try a bit of fieldwork," she suggested. "Go out of your front door and try to spot some live specimens of Homo sapiens in his natural habitat. It shouldn't be difficult because the species is protected by law and in no immediate danger of extinction." After completing obse
Human-induced climate change may seem a purely modern phenomenon. Even in ancient Greece, however, people understood that human activities can change climate. Later the early United States was a lab for observing this as its settlers altered nature. By 1800 it was known that the mass clearing of forests raised temperatures in the Eastern U.S. and that climatic changes followed the pioneers as the
The science you can come across today can often appear to be full of contradictory claims. One study tells you red wine is good for your heart; another tells you it is not. Over the past year, COVID-19 research has offered conflicting reports about the overall effectiveness of wearing a mask. As scientists debate what policy best suits the current moment, they will be drawing on hundreds of studi
