Medical Xpress / Stopping chronic pain before it starts: Surprising biological pathway may play key role
Chronic pain is one of medicine's most stubborn puzzles. A sprained back, a surgical incision or a pinched nerve heals—and yet, for millions of people, the pain never fully goes away. Why some injuries fade into memory while ...
Phys.org / Wrinkled or smooth? Cell growth mechanics determine shape of plant organs
When inner and outer cell layers of sepals—the leaf-like plant organs that cover and protect the flower bud before it opens—all grow upward, the organs stay smooth and uniformly stiff, which is optimal for the plant, according ...
Phys.org / Chimpanzees have accents too, study finds
A study has found that young chimpanzees develop distinct population-specific vocal patterns as they mature (ontogeny), challenging the long-held assumption that their calls are inflexible and determined solely by genetics. ...
Medical Xpress / Some hair loss in men is linked to weight loss drug use
Men already genetically at risk for the most common form of hair loss have a 7% added risk of losing their hair if they use drugs like Ozempic, Wegovy and Zepbound for type 2 diabetes and obesity, a new study shows.
Phys.org / Trees use a 'muscle' to correct their posture—a newly discovered role for tension wood
A research team from INRAE and the University Clermont Auvergne has shown that trees are capable of correcting a curvature they detect in their stems through a specific biological process. In the study, young trees with bent ...
Phys.org / Microbial 'dark matter' yields 173 potential carbon dioxide-fixing strains
There are millions of species of bacteria and archaea on Earth, remarkably little is known about most of them. Now, researchers have mined the genomes of thousands of microorganisms preserved at the RIKEN BioResource Research ...
Tech Xplore / Metal foam front rails could make cars safer in collisions
A new study finds that composite metal foam (CMF) could significantly improve automobile safety during frontal collisions. Using computational models to run detailed simulations, researchers found that incorporating CMF into ...
Medical Xpress / Microdroplets may reduce colorectal tumor growth at potentially lower cost
Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed microscopic peptide droplets that deliver large amounts of gene-silencing molecules into cancer and immune cells, reducing the growth ...
Medical Xpress / Cerebral palsy might be a collection of symptoms, not its own disease
Historically, cerebral palsy (CP) was linked largely to events at birth, including prematurity or temporary loss of oxygen to the brain, but research over the past decade has suggested that genetic factors contribute to CP ...
Phys.org / From pets to zoos: How students perceive animal husbandry
Animals fulfill a wide range of roles in human society. They provide food, contribute to scientific research, live alongside people as companion animals, and play important roles in education, conservation, research and public ...
Phys.org / Not tiger, not wolf: Australian thylacine skull reveals a far different hunting style
A new study led by Flinders University has flipped the historical narrative about Australia's thylacine, finding the native apex predator known as the "Tasmanian tiger" was significantly different from the wolves and wild ...
Phys.org / Mixed grazing, controlled burns and collaboration can curb Mediterranean wildfire risks
Wildfires in the Mediterranean region are becoming drastically more intense. The recent major fires in France, Spain and Greece show that firefighting efforts are reaching their limits.
