In a massive study tracking nearly 100,000 people over more than a decade, researchers found that these medications were linked to significantly fewer psychiatric hospital visits and sick days.

Researchers found that both caffeinated and decaf coffee altered gut bacteria in ways linked to better mood and lower stress. Decaf even improved learning and memory, while caffeine boosted focus and reduced anxiety. Together, they show coffee works through multiple pathways beyond just caffeine.

Infrasound, an ultra-low-frequency vibration below the range of human hearing, is everywhere from traffic to old buildings. In a small experiment, people exposed to it became more irritable, less engaged, and even showed higher levels of the stress hormone cortisol—despite having no idea it was present. The findings suggest our bodies can “sense” these vibrations without conscious awareness, potentially explaining eerie sensations in places like basements or supposedly haunted buildings.

By increasing a protein called Sox9, researchers were able to boost the activity of astrocytes, star shaped cells that help maintain brain health. In mice that already showed memory problems, this approach reduced plaque buildup and preserved cognitive function over time.

Researchers discovered that early neural networks in the hippocampus are dense and seemingly random, then become more organized by shedding connections over time. This pruning process creates a faster, more efficient system for linking experiences and forming memories. It challenges the idea that the brain starts from scratch.

This subtle motion, triggered by pressure changes in connected blood vessels, appears to help circulate cerebrospinal fluid around the brain, potentially flushing out harmful waste.

By mapping millions of neurons in mice, researchers discovered that smell receptors in the nose aren’t random at all—they’re arranged in neat, overlapping stripes based on receptor type, forming a hidden structure scientists never knew existed. Even more striking, this layout mirrors how smell information is mapped in the brain, revealing a coordinated system from nose to neural circuits.

This “pencil beam” enabled them to image the blood-brain barrier in 3D at speeds 25 times faster than existing techniques. The method also lets researchers watch how drugs move into brain cells in real time. It could dramatically accelerate the development of treatments for neurological diseases.

Researchers found that the brain doesn’t just replay daily life—it reshapes it into imaginative, sometimes surreal scenarios. People who mind-wander more tend to have fragmented dreams, while those who value dreams experience richer ones. Even major events like the pandemic changed dream content, making it more emotional and restrictive.

Surprisingly, factors like community support didn’t show the same impact. Researchers say cultural pressures and stereotypes may cause emotional struggles to go unnoticed and untreated. The findings suggest that targeted, culturally sensitive stress relief could play a powerful role in preserving cognitive health.

Scientists found that in people with repeated mild head injuries, a key omega-3 fatty acid in fish oil—EPA—may actually interfere with the brain’s ability to repair itself. Instead of helping recovery, it appears to weaken blood vessel stability, disrupt healing signals, and even contribute to harmful protein buildup linked to cognitive decline.
