Could Your Voice Reveal How Fast Your Brain Is Aging?
Summary: A multicenter study of nearly 3,000 individuals published in Science Advances reveals that machine-learning models can infer a person’s biological age and brain health from vocal patterns. This newly…
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.…
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…
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…
Can Humor Treat Depression? – Neuroscience News
Summary: A comprehensive review of clinical psychology and neuroimaging research shows that while humor can build resilience and protect against depressive relapse, it often does more harm than good during…
