Obesity is a global epidemic and a major cause of morbidity and mortality because it increases the risk for comorbidities, including heart disease and fatty liver disease (MASLD).

A new study published on December 23, 2025, in Neurology, the medical journal of the American Academy of Neurology, looks at how age may affect recovery for people with spinal cord injuries.

A study led by biomedical scientists at the University of California, Riverside, has shown for the first time that a father's exposure to microplastics (MPs) can trigger metabolic dysfunctions in his offspring.

Older adults who live in economically disadvantaged neighborhoods spend significantly fewer days at home in the year after a fall-related hip fracture than those living in more affluent areas, according to a large national study published today in JAMA Network Open.

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and Stanford University have been able to study the implantation of human embryos, opening up this enigmatic process to investigation.

For many of us, the holiday season can mean delightful overeating, followed by recriminatory New Year's resolutions.

Scientists have engineered a protein able to record the incoming chemical signals of brain cells (as opposed to just their outgoing signals).

A new research paper was published in Volume 17, Issue 11 of Aging-US on November 25, 2025, titled "A natural language processing–driven map of the aging research landscape."

Researchers created a nationally consistent, publicly available dataset estimating car-based driving times and distances to key healthcare services across Australia using mesh block–level data. The dataset reveals substantial geographic variation in access, particularly in regional and remote areas, and provides a standardized foundation for future health services research.

Higher intake of high-fat cheese and cream was associated with a lower risk of all-cause dementia over 25 years in a large Swedish cohort, while low-fat dairy showed no association. Associations were strongest for vascular dementia and among APOE ε4 non-carriers, with findings remaining observational.

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.
