Medical Xpress / The rules neurons follow to make sense of what we see
Even in the primary visual cortex, a brain region named for its specialized role in processing basic features of what the eyes see, not every neuron ends up answering the call to process properties of visual input. Maybe ...
Medical Xpress / Fear memories fade faster when brain immune cells engage key neurons, study suggests
Post-traumatic stress disorder (PTSD) and anxiety disorders are often characterized by fearful responses in specific situations that the mind learns to view as threatening. These fearful responses typically emerge following ...
Tech Xplore / Signal-folding design helps neuromorphic chip slash AI energy use
Artificial intelligence systems, such as large language models (LLMs) and convolutional neural networks (CNNs), can analyze large amounts of data and rapidly generate desired content or identify meaningful patterns. However, ...
Medical Xpress / Dinner at the door: Convenient healthy meals may ease depression symptoms
Making healthy meals more convenient through meal delivery services could improve depressive symptoms by removing some of the daily burdens that often accompany depression, according to a new University of Michigan study.
Science X / The ultimate viral stowaways: A Trojan Horse story
Forget hitchhiking; some tiny viruses are playing viral "Trojan Horse," literally sneaking inside other viruses to invade new species and even our brains. It's a microscopic masterclass in stealth infection.
Medical Xpress / Friendly skin bacteria shut down inflammatory driver of eczema
Friendly skin bacteria could hold the key to stopping eczema in its tracks, according to a breakthrough by a team of UK and Japanese scientists. Their new study reveals harmless microbes living on our skin release powerful ...
Phys.org / Rivalry with neighboring groups may be a key driver of male size in primates
In many primate species, males are much larger than their female counterparts, which is generally attributed to male competition for mates (sexual selection). But bigger bodies may not just be about alpha males defeating ...
Medical Xpress / The liver's immune cells might be the key to curing hepatitis B
Fifteen years ago, doctors in Europe noticed a remarkable thing happening in people with chronic hepatitis B infections. When patients went off their medications, the virus started to come back—and then some of the patients ...
Phys.org / Machine-learning method maps the uncertainty of biodiversity scenarios: The Bigfoot connection
To effectively protect biodiversity in an era of climate change, ecologists first have to know where animal and plant species are located and then be able to predict what habitats will be available to them in the future. ...
Phys.org / What gives stevia its sweetness? Scientists uncover the genetic secret
Stevia is a widely used sweetener, but why do some stevia varieties taste cleaner and more sugar-like than others? Recent research conducted at the University of Toyama shows that stevia's sweetness is genetically linked ...
Tech Xplore / Blind ambition: AI agents can turn tasks into digital disasters
Computer scientists at UC Riverside have identified troubling flaws in a new generation of artificial intelligence (AI) agents designed to take over routine computer chores while users are away—sorting emails, organizing ...
Tech Xplore / A single real-world data point may stop AI model collapse, analysis suggests
New work explaining the inner workings of artificial intelligence could provide a way around the threat of AI "model collapse," potentially averting growing numbers of AI hallucinations in the future.
