Medical Xpress / The brain's primitive 'fear center' is actually a sophisticated mediator, research reveals
A Dartmouth study challenges the conventional view that the amygdala—the two-sided structure deep in the brain involved in emotion, learning, and decision making—is simply the brain's primitive "fear center," reflexively ...
Phys.org / Hair-width LEDs could eventually replace lasers
LEDs no wider than a human hair could soon take on work traditionally handled by lasers, from moving data inside server racks to powering next-generation displays. New research co-authored by UC Santa Barbara doctoral student ...
Medical Xpress / Human liver tissue cell architecture reconstructed in 3D at a cellular level
Never-before-seen 3D reconstructions of human liver tissue have been created at a cellular level. The details obtained by a team of UW Medicine and University of Washington engineers and physicians capture the spatial microstructure ...
Phys.org / Jupiter's Galilean moons may have gained life's building blocks at birth
Southwest Research Institute was part of an international team that demonstrated how complex organic molecules (COMs), key chemical precursors to life, could have been incorporated into Jupiter's Galilean moons during their ...
Phys.org / Methane's missing emissions: The underestimated impact of small sources
Methane is a potent greenhouse gas, with an impact estimated at 80 times that of CO₂. Although efforts are being made to reduce the contribution of big polluters to methane in Japan, new research from Osaka Metropolitan ...
Medical Xpress / Novel markers of brain blood flow and oxygenation may offer early clues to Alzheimer's risk
Subtle changes in how blood flows through the brain and how brain tissue uses oxygen may be closely linked to Alzheimer's disease risk, according to new research from the Mark and Mary Stevens Neuroimaging and Informatics ...
Medical Xpress / Opioids aren't effective for many acute pain conditions, researchers warn
A large review of opioid pain relievers prescribed for acute pain has found these medicines provide only small, short-term relief for some acute conditions and are ineffective for some others. The study set out to review ...
Medical Xpress / Doomscrolling affecting many Americans' sleep, poll finds
Doomscrolling is taking a toll on many Americans' rest, a new survey says. More than a third of U.S. adults (38%) say using their phone or tablet to read the news before bed is making their sleep slightly or significantly ...
Medical Xpress / Early healthy eating shapes lifelong brain health, new research finds
Eating unhealthy foods early in life leaves lasting brain and feeding changes, but gut bacteria can help restore healthy eating, a new University College Cork (UCC) research study finds. A high-fat, high-sugar diet during ...
Medical Xpress / Fat shaming doesn't improve human health, it harms it, researchers find
Adolescence is a period defined by rapid physical, emotional, and social change, and for many young people, it is also shaped by body image issues and weight stigma. Those experiences, researchers say, can drive chronic stress ...
Phys.org / Sunlight-powered process turns plastic waste into acetic acid without added emissions
Researchers at the University of Waterloo have discovered a way to turn plastic waste into acetic acid, the main ingredient of vinegar, using sunlight. The breakthrough offers a promising new approach to reducing plastic ...
Phys.org / Twisting optical fiber creates a robust new pathway for light
Light powers everything from communications to sensing, yet even tiny imperfections can scatter it and weaken signals. To address this, a team led by the University of Bath—working with the University of Cambridge and international ...
