How Psilocybin Lifts Mood Without the Hallucinogenic Trip

Researchers have uncovered two key brain mechanisms—specific neurons and a serotonin receptor—that help explain how psilocybin produces long-lasting antidepressant effects. Their study identified pyramidal tract neurons in the medial frontal cortex and the serotonin 5-HT2A receptor as essential to the therapeutic action of psilocybin.

Pupil Dynamics During Sleep Reveal Brain’s Memory-Saving Secrets

Researchers have discovered that pupil size during non-REM sleep correlates with memory consolidation. When pupils contract, the brain focuses on consolidating new memories; when dilated, it processes older ones.

Tiny Walking Robots Advance Micro-Optics and Biological Research

Researchers have developed the smallest walking robots, measuring just 2 to 5 microns, capable of interacting with visible light for imaging and force measurement. These magnetically controlled robots can inch forward or swim through fluids while serving as diffraction elements, enabling super-resolution microscopy at scales previously unattainable.

Psychedelic Drug Reduces Anxiety by Targeting Fast-spiking Interneurons

The psychedelic DOI, a compound similar to LSD, reduced anxiety in mice by activating specific brain cells called fast-spiking interneurons. These neurons silence nearby cells in the ventral hippocampus, a region linked to emotion and memory. By uncovering this mechanism, the study opens the door to designing new treatments that target anxiety without triggering hallucinations, a hallmark of many psychedelics.

Outdoor Enjoyment Linked to Less Inflammation

A new study reveals a biological link between enjoying nature and reduced inflammation levels, which could help in preventing or managing chronic inflammation-related diseases like heart disease and diabetes. The study analyzed data from the Midlife in the U.S. (MIDUS) survey, focusing on 1,244 participants, and found that frequent positive interactions with nature correlated with lower levels of three key inflammation markers.

Unlocking the Dual Memory Codes of the Hippocampus

Researchers have distinguished between two vital memory tasks housed in the hippocampus: one that remembers associations and another that predicts based on past events. The study used optogenetics to isolate one memory function without affecting the other.
