Medical Xpress / Hormone estradiol shapes women's brain responses to threat after trauma, study finds
Women are more than twice as likely as men to develop stress-related conditions such as posttraumatic stress disorder (PTSD), but the biological mechanisms underlying that risk have remained poorly understood. New research ...
Medical Xpress / Assisted reproductive technology associated with higher risk of childhood atopic diseases
Collaborating institutions in Taiwan report higher risks of atopic disease among children conceived via assisted reproductive technology compared to those conceived naturally.
Phys.org / A tug-of-war explains a decades-old question about how bacteria swim
Scientists have uncovered a new explanation for how swimming bacteria change direction, providing fresh insight into one of biology's most intensively studied molecular machines.
Phys.org / New method reveals how mutations drive transthyretin amyloidosis and guides precision drug design
An international research team reveals new molecular mechanisms associated with pathogenic mutations in the protein transthyretin that cause transthyretin amyloidosis (ATTR), a group of fatal progressive diseases. The results, ...
Phys.org / Why we trust romantic partners rather than AI when making big financial decisions
Artificial intelligence programs are not only helping us tackle complex challenges like diagnosing diseases and predicting weather patterns, but also assisting with more mundane matters such as correcting grammar and planning ...
Medical Xpress / Origin cells for common malignant brain tumor in young adults uncovered
IDH-mutant glioma, caused by abnormalities in a specific gene (IDH), is the most common malignant brain tumor among young adults under the age of 50. It is a refractory brain cancer that is difficult to treat due to its high ...
Phys.org / Vegetation might exacerbate urban heat island effect in very dry cities
As temperatures rise around the world, city heat becomes increasingly unbearable during the hottest seasons. The urban heat island effect causes cities to become significantly warmer than surrounding rural areas due to human ...
Tech Xplore / OLED lighting: Corrugated panel design extends longevity and efficiency
The organic light emitting diodes—known widely as OLEDs—that create vibrant smartphone displays could illuminate rooms, but current designs burn out too quickly at the high brightness needed for room lighting. A new approach ...
Medical Xpress / TB harnesses part of immune defense system to cause infection, study finds
Scientists have made a discovery that helps explain why humans and animals are so susceptible to contracting tuberculosis (TB)—and it involves the bacteria harnessing part of the immune system meant to protect against infection.
Medical Xpress / Infants receiving nirsevimab fare better against RSV compared to those with maternal vaccination
Respiratory syncytial virus (RSV) is a common virus that affects the nose, throat, and lungs. For most healthy adults and children, it causes only mild, cold-like symptoms and goes away on its own. Infants under 6 months ...
Phys.org / How quiet galaxies stay quiet: Cool gas feeds black holes in 'red geysers'
Astronomers have long puzzled over how some massive galaxies stop forming stars and remain dormant for billions of years—even when they still contain gas that could, in principle, fuel new stars.
Phys.org / How does glass 'shake' and why does it start flowing when pushed hard enough?
Glassy materials are everywhere, with applications far exceeding windowpanes and drinking glasses. They range from bioactive glasses for bone repair and amorphous pharmaceuticals that boost drug solubility to ultra-pure silica ...
