Phys.org / The Southwest's drought is shrinking wildlife's suitable habitat, with predators hit hardest
As people in the United States are coping with historic drought conditions, the country's wildlife is also facing problems because of the extreme aridity. Herbivores, omnivores, and carnivores in the southwestern U.S. have ...
Phys.org / New 'AI scientists' are improving—but reveal their fundamental limits
Many of the most exciting discoveries in science involve highly specialized knowledge and making connections between far-flung facts. Scientists must combine deep analysis with broad reasoning strategies.
Phys.org / 'Shoot for the moon?' Aim a bit lower, researchers say
How ambitious should you be? Folk wisdom offers conflicting advice: "Shoot for the moon," but also, "Don't let the perfect be the enemy of the good." A new study by researchers at the University of Wyoming, Stanford University ...
Phys.org / A hidden supermassive black hole may be lurking inside the Antennae galaxies
Astronomers may have uncovered a hidden supermassive black hole inside the famous Antennae galaxies NGC 4038/4039, a pair of colliding galaxies best known for their spectacular bursts of star formation. The paper outlining ...
Phys.org / Topological states emerge in quantum Hall-superconductor devices with multiple channels
Topological phases are unusual states of matter that give rise to properties protected by a material's overall structure (i.e., "topology"), as opposed to microscopic details. These phases are of great interest for the development ...
Medical Xpress / Light movement in pregnancy linked to lower risk of complications
Moving more and sitting less could lower the risk of adverse pregnancy outcomes, according to a new study published in the Journal of the American Medical Association.
Tech Xplore / AI and ultralow-energy lasers enable an ultrafast authentication system
The security of modern communications heavily relies on systems that can rapidly and reliably verify users and the devices they are using. This process, known as authentication, essentially entails confirming that users or ...
Science X / As climate change redraws rainfall maps, some regions face a far greater flood risk than others
As the climate warms, heavy downpours are covering more ground—but where exactly? A new study puts the big-picture changes in context, and suddenly, it matters what region you live in.
Science X / Why does stress let your brain learn but prevent you from thinking logically?
The human brain is an incredible processor that can take existing knowledge, such as old memories and experiences, and weave it with newly acquired information to help us draw conclusions and make decisions crucial to navigating ...
Phys.org / Pigeons navigate using magnetic sensors in their livers, say researchers
How pigeons fly hundreds of kilometers and still find their way home has long fascinated people. Now, researchers say a surprising answer may be hidden, not in the brain or eyes of birds, but in the liver.
Phys.org / How bean plants call on wasps for help when hungry caterpillars attack
Some plants are not the sitting ducks they appear to be when they come under attack. If a hungry caterpillar starts to chomp on the succulent leaves of a common bean plant, a highly sophisticated defense system kicks into ...
Phys.org / Bare supercontinent may have tipped ancient Earth into 'Snowball' phase
About a billion years ago, Earth started to come into its own. It was past the awkwardness of its younger years full of growing pains and turmoil: comet strikes and slimy water, including the Great Oxidation Event that flipped ...
