Patients experience significant changes in gut bacteria at the onset of inflammatory bowel disease (IBD), a new international study has found - offering new hope for earlier diagnosis and future treatments.

Memories and learning processes are based on changes in the brain's neuronal connections and, as a result, in signal transmission between neurons.

A team led by clinicians and engineers has wrapped the plant-derived polyphenol pterostilbene (PSB) into prebiotic alginate/resistant-starch microcapsules coated with chitosan and shown that oral administration dampens dextran-sulfate-sodium (DSS) colitis in mice.

Researchers at the University of Sharjah are exploring a promising approach that could enhance the immune system's ability to fight cancer, potentially paving the way for new treatments.

Using marijuana just once or twice a month was associated with worse school performance and emotional distress for teens, according to a large national study of adolescents led by Ryan Sultán, an assistant professor of clinical psychiatry at Columbia University Vagelos College of Physicians and Surgeons.

Our thoughts are specified by our knowledge and plans, yet our cognition can also be fast and flexible in handling new information.

A major review of prior research has found no evidence that menopause hormone therapy either increases or decreases dementia risk in post-menopausal women, in a new study led by University College London (UCL) researchers.

A new systematic evidence review finds that cannabis products that carry relatively high levels of the psychoactive compound tetrahydrocannabinol, commonly known as THC, may provide short-term improvements in pain and function.

After traumatic brain injury (TBI), some patients may recover completely, while others retain severe disabilities.

A study by the Mildred Scheel Early Career Center group led by Dr. Mohamed Elgendy at the TUD Faculty of Medicine provides fundamental insights into cancer biology.

Temporal lobe epilepsy, which results in recurring seizures and cognitive dysfunction, is associated with premature aging of brain cells.

A possible new treatment for impaired brain blood flow and related dementias is on the horizon.

A new study by Scripps Research reveals that alcohol dependence disrupts two signaling pathways in a stress-related part of the brain-and offers insights on developing drugs to treat this condition.

Researchers at the Johns Hopkins Kimmel Cancer Center's Ludwig Center developed a new treatment that selectively targets TRBC2-positive T-cell cancers, expanding a precision approach they established in 2024 for TRBC1-positive tumors.

One of the biggest risk factors for developing liver cancer is a high-fat diet. A new study from MIT reveals how a fatty diet rewires liver cells and makes them more prone to becoming cancerous.

A new study challenges what's long been assumed about genetic variants thought to always cause inherited blindness.

Chimeric antigen receptor T (CAR-T) cell therapy has revolutionized hematologic cancer treatment, but its efficacy in solid tumors remains limited by poor infiltration into the complex tumor microenvironment (TME).

In recent years, scientists have learned that key beneficial infant gut bacteria Bifidobacterium infantis are disappearing from infants in high-resource areas such as the United States and Europe.

A research team at the Nano Life Science Institute (WPI-NanoLSI) and the Faculty of Medicine at Kanazawa University has developed a new class of engineered extracellular vesicles (EVs) capable of inducing antigen-specific regulatory T cells (Tregs), the immune cells that play a central role in suppressing excessive immune responses.

Patients who start their blood pressure treatment with ARB drugs continue with the same medicine to a greater extent than patients who start out with other drugs.
