- ChatGPT answered IVF questions accurately but left gaps doctors flagged
A small comparative analysis presented at the American Society for Reproductive Medicine's annual meeting found that ChatGPT's responses to common IVF questions scored lower than professional...
- Your brain builds emotions from predictions, not hardwired circuits
Lisa Feldman Barrett, a Distinguished Professor of psychology and neuroscience at Northeastern University, argues that feelings like fear and sadness are not fixed biological programs but...
- EPFL chip reads multi-region brain activity to trigger depression stimulation in real time
Engineers at EPFL's Integrated Neurotechnologies Laboratory have built a neural implant chip called LogSync that monitors coordinated electrical activity across 32 brain channels and fires a...
- Brain immune cells, not neurons, drive alcohol damage in mice and human tissue
A Cleveland Clinic team found that microglia, the brain's resident immune cells, actively tear apart the protein scaffolding holding neurons together when exposed to heavy alcohol, rather than...
- AI tool and fruit fly experiments link BRSK1 gene variants to rare brain disorder
Researchers at Baylor College of Medicine and Texas Children's Hospital used an artificial intelligence tool and fruit fly models to connect mutations in the BRSK1 gene to a previously undiagnosed...
- Fish brains have a dedicated circuit for reading a neighbor's panic
Researchers at the University of California San Diego found a midbrain circuit in glassfish that fires when a schoolmate escapes, or simply vanishes. The same ancient brain structure exists in...
- Brain scans reveal five distinct biological subtypes of depression in 263 patients
A University of Helsinki study using high-resolution brain imaging found that people diagnosed with the same condition can have opposite patterns of brain activity. The finding may explain decades...
- Mouse study maps the brain circuit that drives pregnancy food cravings
A team led by researchers at LSU's Pennington Biomedical Research Center has identified a specific neural pathway that appears to drive intense food cravings during pregnancy, in mice. The...
- Pufferfish taste receptor solves a structural puzzle about how flavor is sensed
A University of Osaka team has mapped the first 3D crystal structure of an umami taste receptor from pufferfish, finding a molecular mechanism that lets it detect both savory and sweet amino...
- A child's blink rate tracks cognitive flexibility and prefrontal brain activity
In 113 preschoolers, researchers found that how often a child blinks spontaneously predicts how well they can switch mental rules, and maps directly onto activity in a specific region of the...
- Oura's IPO filing reveals what the ring does not yet do
Oura filed to go public with $500 million in 2024 revenue and ambitions to detect illness and track blood glucose. Its own SEC filing says none of that is FDA-cleared as a diagnostic today. Here...
