A new report by artificial intelligence (AI) and foreign policy experts predicts that deepfakes technology is on the brink of being used much more widely, including in targeted military and intelligence operations. The experts make recommendations to security officials and policymakers for how to handle the unsettling new technology, including a call to develop a code of conduct for governments'...
Researchers have developed a new method to look at the cerebellum in detail.
Physicists have once again gained a deeper understanding of the mechanism behind superconductors. This brings researchers one step closer to their goal of developing the foundations for a theory for superconductors that would allow current to flow without resistance and without energy loss. The researchers found that in superconducting copper-oxygen bonds, called cuprates, there must be a very...
A promising approach to control Staphylococcus aureus bacterial colonization in people -- using a probiotic instead of antibiotics -- was safe and highly effective in a Phase 2 clinical trial. The new study found that the probiotic Bacillus subtilis markedly reduced S. aureus colonization in trial participants without harming the gut microbiota, which includes bacteria that can benefit people.
A diverse immune response hinges on naive B cells mingling with high affinity ones in the late-stage germinal center. Whether that helps or hinders, however, depends on the virus.
María Altamirano, with the Department of Botany and Plant Physiology of the University of Malaga, is a member of the scientific team that collaborates for the Seamounts Project. This project led by the Charles Darwin Foundation (CDF) has discovered an extensive kelp forest on the summit of a seamount, at depths of ~ 50 m, in the south of the Galapagos Islands.
Exposure to high doses of micro-sized polyethylene has adverse effects on cells, a new study from the University of Eastern Finland finds. The researchers investigated the toxicity of micro-sized polyethylene in two different human colorectal cancer cell lines. Being one of our most common plastics, polyethylene is used for a variety of purposes, for example as packaging material.
The world's population may have shot up beyond eight billion for the first time recently, but some countries including the most populous, China, are seeing their populations shrink.
In the coming years, NASA and the European Space Agency (ESA) will send two robotic missions to explore Jupiter's icy moon Europa. These are none other than NASA's Europa Clipper and the ESA's Jupiter Icy Moons Explorer (JUICE), which will launch in 2024, and 2023 (respectively). Once they arrive by the 2030s, they will study Europa's surface with a series of flybys to determine if its interior...
Researchers from a variety of Spanish institutions have managed to reconstruct the diet of some 50 individuals buried more than 3,000 years ago in the Cova des Pas' necropolis in Menorca. The study, coordinated by the UAB, indicates a diet of plants and meat, with all individuals having the same access to food, implying that they were a socially egalitarian group.
With only a small percentage of plastics recycled, determining the best way to recycle and reuse these materials may enable higher adoption of plastics recycling and reduce plastic waste pollution. Researchers at the U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL) examined the benefits and trade-offs of current and emerging technologies for recycling certain types...
It was a cool Thursday morning in Cape Canaveral as the nation's first space shuttle was about to make its last ever trip into space.
The 2,000-year-old inscription is among the earliest examples of words recorded in writingArchaeologists in Norway have found what they claim is the world’s oldest runestone, saying the inscriptions are up to 2,000 years old and date back to the earliest days of the enigmatic history of runic writing.The flat, square block of brownish sandstone has carved scribbles, which may be the earliest...
Amid dramatic ocean swells and drenching atmospheric rivers, a new report lays bare a hidden aspect of sea level rise that has been exacerbating flooding in the Bay Area.
Separation leads to a significant but temporary increase in gender inequalities in parent-child time, according to new research from sociologists in Trinity College Dublin and UNED Madrid, Spain.
New findings from the University of Houston may reverse some of the prevailing wisdom about the scourge of screen time and digital devices in the hands of young children. The research is the first to focus on a child under three and reveals that while digital technology may bore, distract and confuse them, those are the same emotions that promote creativity and learning.
New research shows how humans are a substantial source of mortality for wolves that live predominantly in national parks—and more importantly, that human-caused mortality triggers instability in wolf packs in national parks.
The share of e-commerce retail sales in the United States has grown steadily over the last decade. This trend has been driven by retailers with traditional brick-and-mortar stores adopting online channels to connect to customers. In a new study, researchers explored the world of omnichannel retailing—the merging of in-store and online channels in which customers can select from a combination of...
Sometimes there is a confluence of events in municipal politics that takes a serious problem, a collection of outsized personalities and potty humour and sloshes them around to create headline gold. Such was the Big Flush, an arguably overreported but undeniably rich media bonanza in 2015.
Curtin University research into how echidnas might respond to a warming climate has found clever techniques used by the animal to cope with heat, including blowing bubbles to wet its nose tip, with the moisture then evaporating and cooling its blood.
Spring is the sweet spot for breeding songbirds in California's Central Valley—not too hot, not too wet. But climate change models indicate the region will experience more rainfall during the breeding season, and days of extreme heat are expected to increase. Both changes threaten the reproductive success of songbirds, according to a study from the University of California, Davis.
Political parties formed in Europe by existing parliamentarians are significantly more likely to die, new research shows.
In the blazing upper atmosphere of the Sun, a team of scientists have found new clues that could help predict when and where the Sun's next flare might explode.
