Phys.org / The 'private solution trap': Why richer countries may favor adaptation over public solutions, and who pays
A new study, led by the University of Nottingham and conducted by a team of 72 economists and psychologists across the world, has identified a potential "private solution trap" in problems requiring international cooperation ...
Phys.org / What 'Project Hail Mary' gets right—and wrong—about astrophysics
"Project Hail Mary," the Ryan Gosling-led adaptation of the best-selling sci-fi novel from Andy Weir, is being praised for putting the science in science fiction. Although aliens, sun-draining microorganisms and galaxy-spanning ...
Phys.org / Moons orbiting wandering exoplanets could be habitable—with one catch
Provided they host thick, hydrogen-dominated atmospheres, moons orbiting free-floating exoplanets could retain much of the heat generated deep within their interiors by tidal forces. Led by David Dahlbüdding at the Max Planck ...
Phys.org / How birds send heat into space measured for the first time—a hidden reflectance of feathers
As human-caused climate change continues to raise temperatures across the globe, understanding how birds regulate their temperature is vital for their conservation. But how much heat birds emit—an invisible spectrum of ...
Phys.org / The way you walk can reveal your true feelings
Whether you're striding with purpose, swaggering with confidence, or trudging slowly along the street, the way you walk can reveal how you're feeling, according to new research published in the journal Royal Society Open ...
Phys.org / Discovery of genetic switch could help turn rice into a perennial crop
Rice is a vital crop that feeds more than half of the world's population. In the wild, many rice species are perennials that live for several years, but the varieties we eat today are typically annuals that must be replanted ...
Phys.org / Moby Dick 'ship sinking' sperm whales caught headbutting on camera
New research from the University of St Andrews reports sperm whales headbutting one another. The behavior was captured on film and described scientifically for the first time, confirming accounts by 19th century mariners ...
Medical Xpress / How groups of neurons support the formation of memories
Neuroscientists and psychologists have been trying to understand how the human brain supports learning and the encoding of memories for over a century. Past studies suggest that memories are stored by groups of brain cells ...
Medical Xpress / Mediterranean diet may boost mitochondrial signals linked to heart and brain health
A study led by researchers at the USC Leonard Davis School of Gerontology suggests that the benefits of the Mediterranean diet may be driven, in part, by tiny proteins hidden within our mitochondria, opening a new window ...
Phys.org / Urban blue tits use discarded cigarette butts to protect their nests, study suggests
Discarded litter not only makes our streets and neighborhoods look untidy, but it can also pose a significant risk to wildlife. However, in a surprising development, a study published in the journal Animal Behaviour reports ...
Phys.org / Hawaii tests asphalt made with recycled plastics and fishing nets for shedding
Hawaii has a plastic problem. The island state faces economic and logistical challenges in recycling plastic waste, including marine debris that lingers in its ocean waters. Researchers in Hawaii are pioneering a method to ...
Phys.org / Agricultural soils exposed to controversial weedkiller may be unexpected breeding ground for hospital 'superbugs'
Each year, antimicrobial resistance (AMR) is responsible for an estimated 1.1 to 1.4 million deaths worldwide. Now, scientists have found evidence that the spread of AMR isn't always driven by bacteria evolving to resist ...
