Phys.org / Honduras review confirms 227 native mammal species after eight-year effort
An eight-year international research effort has produced the most comprehensive review of Honduras' mammals since 1998, verifying 227 native species across 146 genera and 42 families, along with three introduced rodent species. ...
Phys.org / Uranus's unusual rotation makes its bow shock expand and contract each day
Within our solar system, Uranus is a geometric oddball. Its spin axis tilts more than 90° from its orbit, so it essentially rolls on its side through space. In contrast, Earth and other planets tilt only moderately or not ...
Medical Xpress / Alzheimer's-linked tau disrupts mitochondria, reversing electron flow in nerve cells
A protein named tau, which has been strongly implicated in the world's No. 1 cause of dementia—Alzheimer's disease—and several other neurodegenerative disorders, may spur these diseases in a way that differs greatly from ...
Phys.org / New quantum microscopy trick quadruples microscope resolution
Three years after a team of Caltech scientists showed that pairs of entangled photons could double the resolution of a light microscope, the same lab has figured out a way to double down on that improvement. They have now ...
Phys.org / New platform speeds bacterial gene mapping for better biotech design
Scientists at the Department of Energy's Oak Ridge National Laboratory have created a platform that pinpoints genetic triggers that turn microbes into efficient factories for new chemicals and materials. The method enables ...
Medical Xpress / Microplastics cross placenta-like barrier and disrupt key pregnancy hormones in new cell model study
Tiny, near-invisible fragments of plastic shed from the products we use every day through sunlight and mechanical wear have been quietly working their way deep into the human body. Microplastics have already been found in ...
Tech Xplore / AI agents automate atom-by-atom simulations to accelerate discovery of new materials
A team from the U.S. Department of Energy's (DOE) Argonne National Laboratory has successfully demonstrated an artificial intelligence (AI)-driven system to automate a powerful simulation method that predicts how atoms in ...
Tech Xplore / RL-100 framework helps robots refine learned tasks amid real-world disruptions
Robots are gradually making their way into a variety of settings, ranging from households to public spaces, offices, factories and health care facilities. Despite their potential, however, many existing robots do not perform ...
Phys.org / Different genes, same result: How flies evolved multiple ways to define heads and tails
One of the most important milestones in the early life of an organism is when the embryo breaks symmetry and arranges itself to form the head (anterior) at one end and tail (posterior) at the other end. Scientists have used ...
Medical Xpress / Why laughter can trigger sudden muscle weakness in people with narcolepsy
Narcolepsy is a chronic neurological condition characterized by disruptions in the regulation of sleep-wake cycles. People with this condition often experience extreme sleepiness during the day and, in some cases, a sudden ...
Phys.org / Powerhouses for fake meat: Muscle protein can now be grown in chloroplasts of lettuce and tobacco plants
Livestock farming requires valuable land to grow fodder, uses vast amounts of freshwater and contributes to global warming through methane and nitrous oxide emissions. And, for many consumers it is important to prevent animal ...
Medical Xpress / What is emotional regulation? A child psychologist explains
If you've followed mental health topics on TikTok or Instagram lately, you have probably heard the term emotional regulation. But emotional regulation isn't just a trendy buzzword. It's a nuanced concept that psychologists ...
