OCD Brains Work Harder to Stay on Track

It’s not just a repetitive thought—it’s a brain working overtime. New research shows why the OCD brain recruits extra regions just to keep track of daily sequences.

Cannabis Blunts Alcohol Cravings

A randomized, placebo-controlled trial shows that cannabis with active THC reduces immediate alcohol cravings and lowers drinking levels in heavy-drinking young adults. After smoking THC, participants not only drank less, they waited longer before taking the first sip and reported lower urges to drink.

Humans and AI Share Similar Learning Strategies

Researchers found that humans and AI share a similar interplay between two learning systems: flexible, quick in-context learning and gradual incremental learning. Experiments showed that AI could develop in-context learning abilities after extensive incremental practice, much like humans do.

Why Your Brain Is Better at Gossip Than You Realize

A new study reveals how humans instinctively calculate who to gossip with by weighing popularity and social distance. This cognitive process allows gossip to spread widely while minimizing the risk of it reaching the wrong person.

Gold Nanoparticles Restore Vision in Macular Degeneration

A new study shows that gold nanoparticles injected into the retina can restore vision in mice with retinal degeneration, offering a less invasive alternative to current retinal prostheses. When activated by patterned infrared light, these nanoparticles stimulate retinal cells, bypassing damaged photoreceptors.

Brain’s Working Memory Limits Tied to Learning, Not Just Capacity

A new study reveals that working memory limitations stem from learning challenges rather than storage capacity. Using a computer model of the basal ganglia and thalamus, researchers showed that holding too much information at once confuses the brain, impairing its ability to learn and use stored data effectively.

How the Body’s Clock Influences Eating and Weight Gain in Teens

A new study reveals that the body’s internal clock plays a key role in eating behavior, influencing when and how much adolescents eat. Researchers found that teens with overweight or obesity consumed significantly more calories later in the day compared to those with a healthy weight. By isolating circadian influences from environmental and behavioral factors, they confirmed that food intake peaks in the late afternoon and evening regardless of sleep duration or external time cues.
