Breastfeeding Through Six Months Tied to Lower ADHD Symptoms, Large Study Finds
A massive study of 37,600 families finds that exclusive breastfeeding for up to six months is linked to lower ADHD symptoms at ages 3, 5, and 8, even after controlling for genetics.
Hearing Aids Linked to 23% Lower Dementia Risk in Epilepsy
A massive study of 250 million health records finds hearing aids cut dementia risk by 23% in epilepsy patients with hearing loss, likely by preserving cognitive reserve.
Optogenetics Restores Motor Learning in Huntington’s Study
Researchers restored motor learning in Huntington’s disease mice by reactivating silent VIP neurons using optogenetics, with benefits lasting days after stimulation ended.
Higher Vitamin C Levels Linked to Larger Gray Matter and Stronger Brain Networks in Older Adults
A large Japanese study of over 2,000 older adults found that higher blood levels of vitamin C are associated with greater gray matter volume and stronger connectivity in key brain networks for memory and attention.
AI Scientist Automates Discovery of Psychological Theories
AutoCog, an autonomous AI system, designs experiments and generates new theories of decision-making, outperforming human-built models.
How AI Models Help Uncover the Brain's Language Secrets
Computational neuroscience uses deep learning to bridge linguistics and brain data, revealing how hierarchical language structures are processed in the brain.
Great Ape Laughter Reveals 15-Million-Year-Old Rhythm That Paved Way for Human Speech
A new study analyzing laughter in humans and four great ape species found an identical rhythmic structure unchanged for 15 million years, revealing the evolutionary foundation of speech.
Placebo Pills Improved Memory Even When People Knew They Were Fake
Healthy older adults who took placebo pills for three weeks showed real improvements in memory, physical performance, and stress — even when they knew the pills were inactive.
Lamprey Brain Map Reveals 450-Million-Year-Old Roots of Vertebrate Intelligence
A single-cell atlas of the lamprey brain shows that our ancient ancestors already had a complex, molecularly organized brain 450 million years ago, with 'moonlighting' neurons that later split into specialists.
New Cell Death Mechanism 'Karyoptosis' Found in Alzheimer's Brains
Researchers discovered karyoptosis, a new form of programmed cell death, in 35% of Alzheimer's frontal cortex neurons, driven by p38 MAP kinase and LaminB1 interaction causing nuclear disintegration.
Small-World Networks Boost Brain-Like Neural Groups, New Simulation Shows
Researchers found that small-world topology maximizes polychronous neuronal groups (PNGs), which may underlie neural computation. A new recurrence-plot decoder identifies PNGs without neuron labels.
How Interaction Strength Organizes Memory in Complex Networks
A new study shows that real interaction strengths organize memory at greater depth than random weights in networks, revealing universal rules for brain function.
