Decoding Emotions Through Skin Signals

Skin conductance offers a promising new way to measure emotional states, bypassing the limitations of facial recognition. In an experiment, volunteers watched videos evoking fear, humor, and family bonding while their skin's electrical properties were recorded.

Personal Gut Environments Shape How We Digest, Absorb Food

Individual differences in gut physiology and environment play a major role in shaping our gut microbiome and how we process food. Using a smart capsule to measure pH, temperature, and pressure, researchers found significant variations in digestion time and gut conditions between people.

Ketone Bodies Clear Damaged Proteins in the Brain

Ketone bodies, known for their role in energy metabolism during fasting, have been shown to directly interact with damaged proteins in the brain, aiding their clearance through autophagy. Researchers discovered that the ketone body β-hydroxybutyrate alters the solubility of misfolded proteins, facilitating their removal and reducing pathological aggregation.

How Alcohol Increases Pain Tolerance, and Aggression

Alcohol not only raises pain tolerance but also amplifies aggression, according to a new study. Researchers found that participants who drank alcohol had higher pain thresholds and were more willing to inflict painful shocks on others.

Visceral Fat May Indicate Alzheimer’s Risk Decades Before Symptoms

A new study links visceral fat, a deep layer of abdominal fat, to increased brain amyloid and tau proteins—key markers of Alzheimer’s disease—decades before dementia symptoms arise. Researchers found that visceral fat accounted for 77% of the relationship between high BMI and amyloid accumulation, while other fat types showed no similar impact. The study highlights how managing visceral fat through lifestyle changes or medication could reduce Alzheimer's risk.

Study Reveals Axons Are Like “Pearls on a String”

A new study challenges the long-held belief that axons, brain cell extensions, are tube-like, revealing instead a "pearl-on-a-string" structure. Using advanced freezing electron microscopy, researchers found these bead-like formations, termed "non-synaptic varicosities," across mouse neurons.

Brain Stimulation Aids Walking Recovery After Spinal Cord Injury

Researchers have identified the lateral hypothalamus (LH) as a key brain region for walking recovery in spinal cord injury (SCI) patients, demonstrating that deep brain stimulation (DBS) can significantly enhance mobility and autonomy. Unlike traditional DBS applications, targeting the LH promotes long-term neurological improvements, even when stimulation is off. A clinical trial showed dramatic outcomes in participants, with restored walking ability and improved daily independence.

Masculine Ideals Double Suicide Risk in Men

Men who strongly adhere to traditional masculine ideologies, such as suppressing emotions and valuing independence, are more than twice as likely to attempt suicide compared to those with more egalitarian views. The study identified three groups of men—Egalitarians, Players, and Stoics—with Stoics being at the highest risk due to their attitudes and behaviors, especially during mental health crises.

Spike Protein Lingers in Brain, Fuels Long COVID

A new study reveals that the SARS-CoV-2 spike protein remains in brain-protective tissues and skull bone marrow for years after infection, potentially driving long COVID's neurological symptoms. Using advanced imaging, researchers discovered elevated spike protein levels in these regions, leading to chronic brain inflammation and increased risks of neurodegenerative conditions.

Family History of Mental Illness Increases Aggression Risk in CTE

A new study reveals that individuals with chronic traumatic encephalopathy (CTE) and a family history of mental illness have a heightened risk of aggression during adulthood, particularly between ages 40 and 59. Researchers analyzed data from 845 men with histories of head injuries, finding that those with both CTE and a family history of mental illness displayed significantly more aggressive behaviors than those with only one risk factor.

AI Outperforms Experts in Predicting Study Outcomes

A new study demonstrates that large language models (LLMs) can predict the outcomes of neuroscience studies more accurately than human experts, achieving 81% accuracy compared to 63% for neuroscientists. Using a tool called BrainBench, researchers tested LLMs and human experts on identifying real versus fabricated study abstracts, finding that the AI models excelled even when neuroscientists had domain-specific expertise.

This shows a line of people, depicting evolution.

Human Brains Evolved Gradually, Not in Sudden Leaps

A new study reveals that modern humans, Neanderthals, and other relatives evolved larger brains through gradual changes within each species, overturning the idea of sudden leaps in brain size. Researchers used the largest-ever fossil dataset spanning 7 million years and advanced statistical methods to reconstruct brain size evolution.
