Medical Xpress / Steep drop in metabolic coenzyme could trigger preterm labor
Declining placental concentrations of a molecule that plays a key role in metabolism appear to trigger the end of pregnancy and hasten labor and delivery, suggesting a study co-led by researchers at UT Southwestern Medical ...
Phys.org / DNA loops reveal how immune cells build millions of antibodies from one genome
How does your body produce millions of antibodies from one genome? New research reveals how two closely related proteins help immune cells fold DNA, connecting distant genetic pieces to create diverse antibodies that help ...
Phys.org / 500-million-year fossil record reveals corals' symbiotic advantage shifted with changing environments
Coral reef ecosystems, widely seen as a climate change bellwether, are more complex than previously understood. A new international study by the universities of Bristol, Wuhan in China, and Erlangen-Nuremberg in Germany reveals ...
Phys.org / Our ovary blueprint is ancient, according to sea stars
At first glance, bat sea stars, the nubbly, orange, many-footed creatures often found on the seafloor, seem about as far from humans as one can get. Appearances can be deceiving, however. Scientists have found evidence showing ...
Phys.org / Long-dismissed gas emerges as a hidden driver of urban air pollution
Researchers from Tampere University and the University of Helsinki have identified an unexpected chemical process that may influence the formation of air pollution particles in urban environments. The study shows that nitric ...
Phys.org / New AI tool identifies wild animals by their unique patterns in real time
Patterns reveal the individual: A novel AI algorithm equips researchers with a powerful new tool to accurately identify individual jaguars, zebras and giraffes in real time based on their unique coat patterns. Biologists ...
Medical Xpress / Low testosterone linked to cancer risk in men
New research shows men with very low testosterone levels are at higher risk of both fatal and nonfatal cancer later in life. But while the research found men with low testosterone were 18% more likely to die of cancer years ...
Phys.org / Zebrafish and fruit flies share the same internal compass mechanism in a case of convergent evolution
Even in darkness, many animals retain a sense of orientation because their nervous system sustains a memory of heading encoded by the activity of head-direction (HD) cells. Animals continuously update this internal compass ...
Phys.org / Horseshoe bats use echolocation to separate background echoes from those of fluttering prey
Many bat species emit echolocation calls and use the returning echoes to find their way, detect the presence of fluttering insects, and locate and catch them. A new study investigated this behavior in greater horseshoe bats ...
Phys.org / Although woodland salamanders have looked the same for millions of years, their physiology has evolved rapidly
For her doctoral dissertation, Yale's Nathalie Alomar decided to study a small amphibian that appeared to have eluded the forces of evolution. She found that there is more to its evolution than meets the eye.
Dialog / Liquid ripples rewrite 130-year-old biological classic: New reflections on the lock-and-key model
This April, when the spring breeze carried the formal acceptance notice of our paper by the Journal of the American Chemical Society to my desk, my thoughts instantly drifted back to the late Phil Geissler. A legendary physical ...
Medical Xpress / Nordic walking significantly reduces depression symptoms in as little as five weeks, trial finds
Walking with poles is often associated with trekking, but these accessories are part of a very effective aerobic activity called Nordic walking. The specially designed poles make it a full-body exercise that engages up to ...
