Daytime Sleepiness in Midlife Tied to Higher Mortality Risk

Excessive daytime sleepiness significantly raises the risk of all-cause mortality in middle-aged women, according to a large study of over 40,000 female veterans. Women between the ages of 50 and 65 who scored high on the Epworth Sleepiness Scale were 16% more likely to die from any cause, even after adjusting for health and demographic factors.

Self-Powered Synapse Brings Human-Like Vision to AI Devices

Researchers have developed a self-powered artificial synapse capable of color recognition with near-human precision. Unlike traditional systems that demand external energy and massive data processing, this device mimics biological vision and generates its own electricity using solar cells.

Midlife Caffeine Intake Linked to Healthy Aging

A long-term study following nearly 50,000 women over 30 years found that drinking caffeinated coffee in midlife is linked to healthier aging. Women who drank regular coffee were more likely to avoid chronic disease, cognitive decline, and physical impairment later in life.

Blocking Brain Inflammation Molecule May Halt Alzheimer’s

A new study has uncovered a surprising culprit in the progression of Alzheimer’s disease: the immune molecule STING. Scientists found that STING, normally involved in defending the brain, becomes hyperactive with age, causing harmful inflammation and accelerating brain damage.

How Cocaine Hijacks the Brain

In a groundbreaking study, researchers have engineered fruit flies that voluntarily consume cocaine, creating the first fly model for cocaine addiction. Typically, flies avoid the drug due to its bitter taste, but by disabling their bitter-sensing receptors, scientists encouraged addictive behavior within just 16 hours of exposure.

How Humans Emotionally Bond With AI

As AI becomes more integrated into daily life, researchers are investigating whether emotional attachment to AI mirrors human interpersonal relationships. A new study from Japan introduces a scale to assess how people form attachment-like bonds with AI, finding that some users seek emotional reassurance while others prefer distance. T

Night Owls More Impulsive Than Morning Larks

A new study reveals that adolescents who identify as “night owls” tend to be more impulsive than their early-rising peers. These teens reported higher negative urgency and lower perseverance, meaning they were more likely to act rashly under stress and abandon difficult tasks.

How Rhythm Rewires the Brain Moment by Moment

When you listen to a steady rhythm, your brain doesn’t just process it—it reconfigures itself in real time. A new study introduces FREQ-NESS, an advanced neuroimaging method that reveals how different frequencies of brainwaves form dynamic networks across the brain.

Inhibitory Neurons May Hold the Key to Spatial Learning and Memory

A new study explores how the brain quickly learns and remembers important locations by focusing not on excitatory neurons, but on inhibitory ones called parvalbumin interneurons (PVs). These PVs act like circuit breakers, briefly reducing their activity to allow learning-related neurons to strengthen connections. Using optogenetics and virtual reality mazes in mice, researchers found that learning was blocked when PV inhibition didn’t decrease at the right time.

T Cells Found Living in Healthy Brains

Contrary to long-standing beliefs, T cells—key immune cells—have been discovered in the healthy brains of both mice and humans. These cells, previously thought to only enter the brain during disease, were most concentrated in a region that regulates hunger and thirst.

Blocking Opioid Receptors May Restore Healthy Dopamine Balance

New research identifies a promising strategy for correcting dopamine imbalances in the brain using a drug that blocks kappa opioid receptors (KOR). In mouse models with a rare mutation that causes dopamine to leak abnormally, KOR blockers reduced this leakage and restored normal behavior.
