Scientists are uncovering a new possibility behind long COVID's stubborn symptoms: hidden infections that awaken or emerge alongside SARS-CoV-2. Evidence is mounting that viruses like Epstein-Barr and even latent tuberculosis may flare up when COVID ...

Scientists found that certain molecules made by gut bacteria travel to the liver and help control how the body uses energy. These molecules change depending on diet, genetics, and shifts in the microbiome. Some even improved insulin response in liver ...

Senescent "zombie" cells are linked to aging and multiple diseases, but spotting them in living tissue has been notoriously difficult. Researchers at Mayo Clinic have now taken an inventive leap by using aptamers--tiny, shape-shifting DNA molecules- ...

Forskolin, a plant-derived compound, shows surprising potential against one of the most aggressive forms of leukemia. Researchers discovered that it not only stops cancer cells from growing but also makes them far more vulnerable to chemotherapy by . ...

Researchers used a deep learning AI model to uncover the first imaging-based biomarker of chronic stress by measuring adrenal gland volume on routine CT scans. This new metric, the Adrenal Volume Index, correlates strongly with cortisol levels, ...

A decade-long study of older women found that tea drinkers had slightly stronger bones, while moderate coffee drinking caused no harm. Heavy coffee intake--over five cups a day--was linked to lower bone density, especially in women who consumed more ...

Scientists exploring how the brain responds to stress discovered molecular changes that can influence behavior long after an experience ends. They also identified natural resilience systems that help protect certain individuals from harm. These ...

A new analysis suggests that people with type 2 diabetes who use GLP-1 medications like Ozempic, Trulicity or Victoza may be less likely to develop epilepsy than those taking DPP-4 inhibitors. Semaglutide showed the strongest connection to lowered .. ...

Researchers discovered that children who went back to school during COVID experienced far fewer mental health diagnoses than those who stayed remote. Anxiety, depression, and ADHD all declined as in-person learning resumed. Healthcare spending tied . ...

Researchers used AI to pinpoint a little-known monkeypox protein that provokes strong protective antibodies. When the team tested this protein as a vaccine ingredient in mice, it produced a potent immune response. The discovery could lead to simpler, ...
