A large McGill University study has found that two classes of medications commonly prescribed for Type 2 diabetes, both incretin-based, are associated with a reduced risk of dementia.

Bio-engineered skin grafts can play an important role in the treatment of burn victims. Researchers at the University of Zurich have been working on new approaches for such grafts for over 15 years.

Obesity causes hypertension. Hypertension causes cardiovascular disease. And cardiovascular disease is the leading cause of death worldwide.

Pancreatic ductal adenocarcinoma (PDAC) is the most common type of pancreatic cancer and begins in the cells lining the pancreatic duct.

Sickle cell anemia is the world's most common genetic disorder. It causes the red blood pigment hemoglobin to crystallize, which results in rigid, malformed red blood cells with a sickle shape.

A study links excessive screen time in children to higher body fat and poor metabolic health, highlighting cardiorespiratory fitness as a protective factor.

The study reveals deep inequalities in cervical cancer mortality linked to smoking and unsafe sex, highlighting the need for targeted prevention strategies.

Weekly cannabis use accurately predicts the risk of developing cannabis use disorder.

Therapies that target the utilization of fat by tumors and activate a type of cell death dependent on fat molecules may be a promising avenue to treat cancer, according to new research by UTHealth Houston.

The immune system remains seriously out-of-whack – in an inflammatory state of overactivation and impaired functionality – following the international gold standard for treating people with latent tuberculosis (TB) and HIV, a team at Texas Biomedical Research Institute reports in Nature Communications.

Cholera remains a major global public health challenge, with an estimated 1.3 to 4 million cases and tens of thousands of deaths reported worldwide each year.

Wearing a cast for six weeks appears to be no less effective than surgery for healing unstable ankle fractures and carries fewer treatment related harms, finds a clinical trial from Finland published by The BMJ today.

Children born to mothers who consume a high-fat, high-sugar diet during pregnancy and breastfeeding face a higher risk of developing fatty liver disease later in life.

UF Health Cancer Institute researchers have discovered a small compound produced naturally by gut bacteria that doubled the response to lung cancer immunotherapy treatment in mice and can now be made into a drug for testing in humans.

Scientists have identified a promising target for treatment of a devasting autoimmune disease affecting the brain.

Pregnant individuals with inflammatory bowel disease (IBD) have higher levels of pro-inflammatory immune molecules, known as cytokines, in their vaginal mucosa than their healthy counterparts, according to a new study published January 14, 2026 in the open-access journal PLOS One by Ana Maldonado-Contreras of University of Massachusetts Chan Medical School, U.S., and colleagues.

Using participant skin cells reprogrammed into neurons, Weill Cornell Medicine researchers have identified genetic signatures associated with HIV infection that may contribute to the cognitive impairment that often occurs in people living with HIV, even when the virus is controlled.

Autoimmune diseases such as multiple sclerosis arise when the immune system turns against the body itself.

Researchers have identified bradycardia-an abnormally low heart rate–as a symptom of xylazine-opioid overdose.

Dealing with an infection isn't as straightforward as simply killing the pathogen. The body also needs to carefully steer and monitor its immune response to prevent collateral damage.
