Medical Xpress / Scientists track real-time signaling in T cell activation to show how the immune system defends against threats
T cell activation—the process by which these key immune defenders recognize threats and mobilize against them—depends on exquisitely timed molecular signals. Now researchers have captured one of the earliest moments of ...
Tech Xplore / A better method for identifying overconfident large language models
Large language models (LLMs) can generate credible but inaccurate responses, so researchers have developed uncertainty quantification methods to check the reliability of predictions. One popular method involves submitting ...
Medical Xpress / Pythons' feast-and-famine life hints at new weight loss pathway
Pythons don't nibble. They chomp, squeeze, and swallow their prey whole in a meal that can approach 100% of their body weight. But even as they slither stealthily around the forest, months or even a year may pass between ...
Phys.org / Earth's toughest microbes could help save the planet and find life on other worlds
Extremophiles may well be tiny, but they are making a huge contribution to the health of our planet and our lives. A new review of these microorganisms, published in the journal Frontiers in Microbiology, explains how they ...
Medical Xpress / Synaptic connectivity alone can reveal neuron types
Recent technological advances facilitate the reconstruction of complete brain connectomes in small organisms and partial connectomes in mammals, involving the mapping of the network of neurons and synaptic connections. Accurate ...
Phys.org / World Happiness Report highlights social media's negative impact, ranks Finland as happiest country
Heavy social media use contributes to a stark decline in well-being among young people, with the effects particularly worrying in teenage girls in English-speaking countries and Western Europe, according to the World Happiness ...
Medical Xpress / Direct nervous system link promises more natural leg prostheses
A research team led by researchers at Chalmers University of Technology in Sweden, has, for the first time, successfully decoded leg movements directly from the remaining nerves in people with above-knee amputations. Using ...
Medical Xpress / A decade of baseball data shows the designated hitter system does not affect how teams win
In the original form of baseball, all nine players bat and play defense, including the pitcher. The designated hitter system lets a team add a tenth player to the starting lineup—a specialist batter who replaces the pitcher ...
Phys.org / Some 'designer' crossbreed dogs may have more problem behaviors than pure breeds
In a new, survey-based study of three kinds of "designer" crossbreed dogs, cockapoos, cavapoos and labradoodles, all three showed more undesirable behaviors than at least one of their purebred progenitor breeds, with cockapoos ...
Medical Xpress / Switching from milk to solid food in early life helps reprogram the gut's immune defenses, researchers find
According to a team of researchers at Baylor College of Medicine, Tongji University and collaborating institutions, weaning or switching from milk to solid food in early life doesn't just change what babies eat, it helps ...
Phys.org / Experiment challenges hypothesis of cell-like membranes on Titan
New experimental results have cast doubt on earlier proposals suggesting that spherical, cell-like membranes could form in the methane lakes of Saturn's largest moon. Through results published in Science Advances, Tuan Vu ...
Phys.org / New DNA evidence reveals the complex origin of Palau's first settlers
A new genetic study published in the journal Cell is filling in some important details about the earliest inhabitants of Palau, an island nation in the western Pacific Ocean consisting of approximately 340 islands.
