Tech Xplore / HEART benchmark assesses ability of LLMs and humans to offer emotional support
Large language models (LLMs), artificial intelligence (AI) systems that can process human language and generate texts in response to specific user queries, are now used daily by a growing number of people worldwide. While ...
Phys.org / Fast-paced lives demand faster vision: Ecology shapes how 'quickly' animals see time
Animals don't just see the world differently from one another, they experience time itself at dramatically different speeds. That is according to a new study that considered 237 species across the animal kingdom, and which ...
Medical Xpress / 'Off the shelf' immunotherapy could get a lift from gene-edited natural killer cells
Since scientists first discovered that human immune cells could be modified to become cancer-fighting agents, they've been trying to engineer a cell that's effective against solid tumors, which account for the vast majority ...
Medical Xpress / Black Americans face increasingly higher risk of gun homicide death than white Americans
Firearm homicide death rates have long been disproportionately higher for Black Americans compared to white Americans, and a new analysis across 45 years suggests that in recent years, this disparity has grown. Alex Knorre ...
Phys.org / Iron and blue LEDs synthesize natural molecules, cutting the need for expensive chiral components
Photocatalysts facilitate chemical reactions by absorbing light. Metal-based photocatalysts are widely used in organic synthesis due to their durability and the ability to tune their function by modifying the ligands attached ...
Medical Xpress / Keto diet may restore exercise benefits in people with high blood sugar
To be healthy, conventional wisdom tells us to exercise and limit fatty foods. Exercise helps us lose weight and build muscle. It makes our hearts stronger and boosts how we take in and use oxygen for energy—one of the ...
Phys.org / Viruses reveal shared way to kill bacteria by jamming small transporter MurJ
Biochemists at Caltech have identified how viruses have converged on a method for killing bacteria. The researchers have homed in on an underexplored small transporter called MurJ that is a vital part of the pathway bacteria ...
Medical Xpress / Vitamin B7 reveals a new metabolic weak spot in some cancers
A research group at the University of Lausanne (Unil) has identified a new mechanism that exposes the vulnerability of tumor cells when they are deprived of vitamin B7. The ability of cells to adapt to fluctuations in nutrient ...
Medical Xpress / Gallbladder cancer could soon be detected in blood
Researchers at Tezpur University in Assam, India, working with scientists at the University of Illinois Urbana-Champaign, have identified distinct chemical signatures in blood that could help detect gallbladder cancer earlier. ...
Phys.org / One of the biggest stars in the universe might be getting ready to explode
One of the largest known stars in the universe underwent a dramatic transformation in 2014, new research shows, and may be preparing to explode. A study led by Gonzalo Muñoz-Sanchez at the National Observatory of Athens, ...
Medical Xpress / Skeletal muscle retains a 'molecular memory' of repeated disuse, study finds
Muscle loss (atrophy) due to inactivity is common after illness, injury, hospitalization or falls, and becomes increasingly frequent with aging. New research published in Advanced Science shows that skeletal muscle retains ...
Medical Xpress / AI, monkey brains, and the virtue of small thinking illuminate how the brain processes sight
What does it take to make AI that can pass as human? Try massive clusters of supercomputers. To build human-like intelligence, computer scientists think big. However, for neuroscientists who want to understand how real brains ...
