The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Fear strongly influences pain perception in inflammatory bowel disease patients

Pain perception in affected individuals is more strongly influenced by learned fear than in healthy individuals. Changes along the gut-brain axis related to chronic inflammation may explain this.

Massive genetics study shows what truly separates and unites 14 psychiatric disorders

This large-scale genomic analysis of 14 psychiatric disorders shows that most heritable risk is shared across five broad genetic factors, with only limited disorder-specific variation. The study maps where risks converge or diverge biologically, revealing distinct cell type signatures and developmental pathways that may guide future diagnostic and therapeutic frameworks.

Internet gaming disorder affects one in ten boys

Do your kids play a lot of computer games? Some may end up gaming a little too obsessively. Researchers have identified the most important warning signs.

New blood biomarker predicts brain damage after cardiac arrest

A blood biomarker yet to be used in cardiac arrest care can give a clearer picture of the extent of brain damage after a cardiac arrest.

Study reveals shared genetic roots across multiple psychiatric disorders

Distinct psychiatric disorders have more in common biologically than previously believed, according to the largest and most detailed analysis to date of how genes influence mental illness.

Study reveals stepwise formation of cerebellar projections in the developing brain

A team of researchers at the Institute for Neurosciences (IN), a joint center of the Spanish National Research Council (CSIC) and Miguel Hernández University of Elche (UMH), has reconstructed for the first time how the cerebellum establishes its connections with the rest of the brain during the earliest stages of life.

New molecular ruler enables precise measurement of toxic Tau fibrils in fluid samples

Researchers have developed a new tool, FibrilPaint combined with the FibrilRuler test, that allows scientists to directly measure the length of toxic Tau amyloid fibrils in tiny fluid samples, from the earliest aggregation stages to mature fibrils and even at very low concentrations.

Researchers identify enzyme linked to myelin damage and neurodegenerative conditions

Researchers at Oregon Health & Science University have identified a type of enzyme with a complicated name - cell migration inducing and hyaluronan-binding protein, or CEMIP - is associated with disorders ranging from multiple sclerosis to stroke to neurodegenerative conditions like Alzheimer's disease.

Researchers discover the enzyme responsible for chromothripsis in cancer

University of California San Diego researchers have discovered the enzyme responsible for chromothripsis, a process in which a single chromosome is shattered into pieces and rearranged in a scrambled order, allowing cancer cells to rapidly evolve and become resistant to treatment.

Teenagers with body image issues may develop eating disorders and depression later

Teenagers who are unhappy with their bodies are more likely to develop symptoms of eating disorders and depression in early adulthood, according to a new study led by UCL researchers.

Researchers identify a distinct immuno-inflammatory biomarker across major psychiatric disorders

Individuals with psychiatric disorders exhibiting seemingly similar symptoms often respond very differently to the same treatment, suggesting that distinct biological processes are at work beneath the surface of similar clinical presentations.

Missing piece of myelin results in slower, less consistent signal transmission to the brain

Our nerve cells are surrounded by a protective layer (myelin). This protective layer allows signals to pass between cells incredibly quickly.

Shared genetic roots of 14 psychiatric disorders revealed

Researchers from the Psychiatric Genomics Consortium (PGC) report that most genetic influences on mental illness are shared across diagnostic categories, revealing a more interconnected biological landscape than traditional classifications suggest.

What happens to your body during an ultramarathon? New study reveals key metabolic changes

This study tracked ultramarathon runners across 100 km, 160.9 km, and 230 km events to examine real-world metabolic, hormonal, and muscle stress responses. Severe energy deficits, muscle damage, and heterogeneous hormonal shifts were observed, with the greatest strain seen in the 230 km distance.

How much omega-3 do you need daily? New global review reveals DHA and EPA requirements

Global and national guidelines for long-chain omega-3 intake vary widely across life stages, with many countries lacking clear recommendations. Most authorities advise at least 250 mg/day of EPA and DHA, yet population intakes remain far below optimal levels.

Glucose-lowering drugs may reduce risk of developing epilepsy

A preliminary study of people with diabetes suggests that use of glucose-lowering GLP-1 drugs may be linked to a lower risk of developing epilepsy. The study was published on December 10, 2025, in Neurology, the medical journal of the American Academy of Neurology.

New AAN guideline offers treatment strategies for functional seizures

To help neurologists, mental health clinicians and other clinicians determine the best ways to help people manage functional seizures, the American Academy of Neurology has issued a new guideline, published on December 10, 2025, in Neurology, the medical journal of the American Academy of Neurology.

Screen time and ADHD: why social media stands out from gaming and TV

Over four years in a large US cohort, greater social media use was associated with small but consistent increases in inattention symptoms in children, while video games and television were not. Genetic risk for ADHD did not modify this inattention association, and analyses supported a directional link from social media use to later attention difficulties.

AI turns routine pathology slides into powerful maps of the tumor immune landscape

A large study shows that routine H&E pathology slides contain rich spatial proteomic signals that can be decoded by AI to model the tumor immune microenvironment at population scale. By generating virtual multiplex immunofluorescence images, GigaTIME enables pan-cancer discovery of immune patterns linked to invasion stage, survival, and genomic alterations.

Deep learning uncovers why synthetic cannabinoids cause harmful effects

New psychoactive substances, originally developed as potential analgesics but abandoned due to adverse side effects, may still have pharmaceutical value if researchers could nail down the causes of those side effects.
