Researchers at the University of Alabama at Birmingham, Cyprus University of Technology and University College London have conducted the first large-scale measurement of how mainstream and alternative news flows through multiple social media platforms.
Nearly two-thirds of Americans (63 percent) say the future of the nation is a very or somewhat significant source of stress, slightly more than perennial stressors like money (62 percent) and work (61 percent), according to the American Psychological Association’s report, Stress in America™: The State of Our Nation.
Planting cannabis for commercial production in remote locations is creating forest fragmentation, stream modification, soil erosion and landslides. Without land-use policies to limit its environmental footprint, the impacts of cannabis farming could get worse, according to a new study published in the November issue of Frontiers in Ecology and the Environment.
They are nature’s very own Death Star beams – ultra-powerful jets of energy that shoot out from the vicinity of black holes like deadly rays from the Star Wars super-weapon. Now a team of scientists led by the University of Southampton has moved a step closer to understanding these mysterious cosmic phenomena – known as relativistic jets – by measuring how quickly they ‘switch on’ and start shining brightly once they are launched.
An older Neandertal from about 50,000 years ago, who had suffered multiple injuries and other degenerations, became deaf and must have relied on the help of others to avoid prey and survive well into his 40s, indicates a new analysis published Oct. 20 in the online journal PLoS ONE.
Dogs produce more facial expressions when humans are looking at them, according to new research from the University of Portsmouth.
Four Northwestern University astronomers are part of an international research collaboration that is the first to detect the spectacular collision of two neutron stars using both gravitational waves and light. The discovery ushers in an exciting new era in astronomy -- multi-messenger astronomy with gravitational waves -- less than two years after the first detection of gravitational waves opened a new window onto the universe. The astronomers hold leading roles on both sides of discovery, in gravitational-wave astronomy and electromagnetic astronomy.
Carbon dioxide measured by a NASA satellite pinpoints sources of the gas from human and volcanic activities, which may help monitor greenhouse gases responsible for climate change.
Financial losses could increase by more than 70 percent by 2100 if oceans warm at the worst-case-scenario rate predicted by the Intergovernmental Panel on Climate Change, according to a new study. The study used hurricane modeling and information in FEMA's HAZUS database to reach its conclusions.
Researchers at Penn State College of Medicine and Cold Spring Harbor Laboratory have reported the first-ever quantitative whole-brain map of inhibitory neurons in the mouse brain.
Researchers have shown, for the first time, that reduced dietary potassium promotes elevated aortic stiffness in a mouse model. Such arterial stiffness in humans is predictive of heart disease and death from heart disease, and it represents an important health problem for the nation.
In the Middle Ages, did contracting leprosy necessarily increase a person's chances of dying? Yes, says a new paper. But it's complicated.
An international research team, including astronomers from the University of Portsmouth, has revealed evidence of dynamical dark energy.
Researchers at University of California San Diego School of Medicine have developed the first mice that lack the Upf3b gene, providing a new model for studying its underlying role in intellectual disabilities and neurodevelopmental disorders.
NASA's Hubble Space Telescope has photographed the farthest active inbound comet ever seen, at a whopping distance of 1.5 billion miles from the Sun (beyond Saturn's orbit).
Dieting could be revolutionised, thanks to the ground-breaking discovery by the University of Warwick of the key brain cells which control our appetite.
Students and a scientist at the University of Vermont have discovered 15 new species of 'smiley-faced' spiders--and named them after, among others, Barack Obama, Leonardo DiCaprio, and Bernie Sanders.
Satellite data shows underground water reserves in California’s Silicon Valley rebounded quickly after the recent severe drought. The research points to the success of aggressive conservation measures and lays the groundwork for low-cost monitoring of subterranean water reserves around the world.
Fifty years ago, scientists discovered that the Earth is occasionally hit by cosmic rays of enormous energies. Since then, they have argued about the source of those ultra-high energy cosmic rays—whether they came from our galaxy or outside the Milky Way. The answer is a galaxy or galaxies far, far away, according to a report published Sept. 22 in Science by the Pierre Auger Collaboration.
Human activities could change the pace of evolution, similar to what occurred 66 million years ago when a giant asteroid wiped out the dinosaurs, leaving modern birds as their only descendants. That's one conclusion drawn by the authors of a new study published in Systematic Biology.
