Phys.org / New frog species discovered in the Amazon's flooded forests
Scientists from Brazil and other countries have discovered a new species of frog in the flooded forests of the western Amazon. They named it Adenomera varcena. This finding significantly advances our understanding of Amazonian ...
Medical Xpress / Lonely people can feel their heartbeat clearly like everyone else, but their brains respond differently
For a long time, psychologists have described loneliness as the discomfort that comes from wanting more social connection than we feel we have, but there is more nuance to loneliness. Scientists are increasingly finding that ...
Medical Xpress / People carrying a rare gene variant have naturally low body fat, healthier livers and better blood sugar levels
There are people around us who can maintain their weight despite what they eat. This has led scientists to believe that a person's metabolism and tendency toward obesity may have genetic factors behind them. A large study ...
Phys.org / Historical DNA reveals largetooth sawfish have lost much of their genetic diversity
The genetic diversity of the largetooth sawfish (Pristis pristis), a critically endangered ray, has plummeted over the past century and a half, according to a study published in the Proceedings of the Royal Society B: Biological ...
Phys.org / AI tool could help veterinarians track heart disease more precisely
For dogs with heart disease, a fraction of a centimeter can make a life-changing difference. Veterinarians often rely on chest radiographs to monitor subtle changes in heart size that help determine when treatment should ...
Phys.org / History, not age, determines the genomic importance of ancient trees
Ancient trees—those that are remarkably old for their species—are declining worldwide, raising concerns about the loss of the ecological and evolutionary history they represent. Their exceptional longevity has long encouraged ...
Phys.org / Spontaneous magnons synchronize with external signals at room temperature
Signals ride on waves of one kind or another: light, sound, radio. But new carriers are needed to relay information in next-generation devices. Disturbances or waves in magnetic materials called magnons could be an efficient ...
Medical Xpress / Unexpected findings add new insight on cannabis and heart health
Habitual cannabis users experienced about 9% fewer premature heartbeats on days they inhaled cannabis compared with days they abstained, a counterintuitive finding that adds to the complex and evolving understanding of how ...
Phys.org / Arctic fossil abandoned in 1948 proves to be record-size Triassic hunter
Nearly 80 years ago, a British expedition discovered the battered remains of a giant fossil on the peak of an Arctic island. Unable to take it with them, they snapped some pictures, took some bones and left the fossil to ...
Medical Xpress / How brain ripples help support working memory
Research from scientists at the University of California San Diego School of Medicine and collaborators has shed new light on how the human brain coordinates working memory, the process in which the brain encodes information ...
Phys.org / What happens to nanoparticles when they enter the bloodstream?
The use of nanoparticles in drug delivery offers key advantages: they can enable targeted drug delivery, protect active ingredients from premature degradation, extend their duration of action in the body and reduce side effects. ...
Tech Xplore / An energy storage device designed to be recycled
Smartwatches, phones and even some drones rely on lightweight, rechargeable energy storage systems. Once those devices wear out, many end up as electronic waste. Now, researchers reporting in ACS Energy Letters have developed ...
