Scientists have uncovered a surprising link between simple body movement and brain health: every time you tighten your abdominal muscles—even slightly—your brain may gently sway inside your skull。 This subtle motion, triggered by pressure changes in connected blood vessels, appears to help circulate cerebrospinal fluid around the brain, potentially
Engineers at Northwestern University have taken a striking leap toward merging machines with the human brain by printing artificial neurons that can actually communicate with real ones。 These flexible, low-cost devices generate lifelike electrical signals capable of activating living brain cells, a breakthrough demonstrated in mouse brain tissue
Scientists have discovered a way to help the brain clean itself of harmful Alzheimer’s plaques by activating its own support cells。 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 plaq
Scientists at MIT discovered that chaotic laser light can spontaneously form a highly focused beam instead of scattering—if the conditions are just right。 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 i
Fish oil has long been praised as brain-boosting, but new research suggests the story may be more complicated。 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 sta
A breakthrough in brain-inspired computing could make today’s energy-hungry AI systems far more efficient。 Researchers have engineered a new nanoelectronic device using a modified form of hafnium oxide that mimics how neurons process and store information at the same time。 Unlike conventional chips that waste energy moving data back and forth, this
Deep within the brain, scientists have uncovered a hidden “switch” that may decide whether pain fades away—or lingers for months or even years。 Researchers found that a small, little-known region called the caudal granular insular cortex (CGIC) acts like a command center, telling the body to keep pain signals alive long after an injury has healed。

A gut bacterium may be quietly fueling depression through an unexpected chemical twist。 Researchers found that when Morganella morganii interacts with a common pollutant, it produces a molecule that triggers inflammation—something strongly linked to depression。 This finding helps explain how gut microbes can influence brain health at a molecular le
Dreams are more structured than they seem, shaped by both personal traits and real-world experiences。 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
Scientists have finally cracked one of the biggest mysteries in the senses: how smell is organized。 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
