Neurodevelopmental Syndrome Linked to Partial Loss of BRSK1
Summary: Using the artificial intelligence tool AI-MARRVEL alongside functional fruit fly models, researchers have identified rare variants in the BRSK1 gene as the underlying cause of an undiagnosed neurodevelopmental condition.…
Peru’s penguins are on the brink. A super El Niño could make it worse.
The first time I was in Punta San Juan, the desert was flooded with birds. It was 2012, and I was making a short documentary film about the cormorants, pelicans…
Current and future RFK Jr. aides criticize his science-rejectionist vaccine views
Health Secretary Robert F. Kennedy Jr. has spent years casting doubt on vaccines, but the people lined up to work for him keep saying the opposite. Since the White House…
Flawed AI Summaries Distort Eyewitness Memory
Summary: AI-generated summaries can manipulate eyewitness memory, causing people to misremember events they witnessed firsthand. In a controlled experiment, exposure to misleading automated summaries nearly halved participants’ recall accuracy, implanting…
Mitochondria in the Brain’s Reward Hub Drive Nicotine Dependence
Summary: Supported by a $943,000 NIH grant, neuroscientists at the University of Central Florida are investigating how nicotine alters neuronal mitochondria within the nucleus accumbens. By examining the subcellular mechanisms…
Viewpoint: 4 very real AI doomsday scenarios
An engineered pandemic, a nuclear war, a planet paved over with paper clip factories: AI researchers have floated plenty of ways the technology could end humanity. Now the debate over…
Cell Membrane Lipid Governs Retinal Light Sensitivity
Summary: Using cryogenic electron microscopy and synthetic model membranes, researchers have mapped how the membrane phospholipid PIP2 binds to cyclic nucleotide-gated (CNG) ion channels in retinal rod cells. Even at…
