New research by engineers at the University of Colorado Boulder aims to get to the bottom of why, as the saying goes, you get a "skip in your step" when you're happy.

Scientists at the University of California, Irvine's School of Pharmacy & Pharmaceutical Sciences have discovered how muscle stem cells "flip a switch" to rebuild damaged muscle – a finding that could help address muscle loss linked to aging, injury and widely used weight-loss medications.

At Super Bowl parties, weddings, Independence Day cookouts and Thanksgiving dinners, people celebrate with large spreads of food.

Refugee and immigrant children are less likely to visit the emergency department (ED) for minor illnesses (e.g., respiratory infections) compared to children born in Ontario, according to a new study from ICES and The Hospital for Sick Children (SickKids).

When the immune system detects a harmful or foreign agent it triggers an inflammatory response small proteins called chemokines direct immune cells to the site of the injury or infection, resulting in the invader being inactivated.

Hantaviruses, transmitted from rodents to people, have a death rate approaching 40%. They're found around the world, and because there are no approved vaccines or treatments, they're among the pathogens of highest concern for future pandemics.

The pathogens that cause tropical diseases rely on an essential protein that is absent from all other organism. This discovery opens the possibility for targeted treatment.

Study reveals how two proteins cooperate in a key early step of antiviral detection, as reported by researchers at Science Tokyo.

A new research paper was published in Volume 18 of Aging-US on February 6, 2026, titled "Causal effects of inflammation on long-term mortality: a Mendelian randomization study."

An AI can accurately diagnose a rare endocrinological condition just by analyzing pictures of the back of the hand and the clenched fist.

Plastic products are ubiquitous in our food supply chain, shedding microplastics into every part of the human ecosystem.

DNA polymerase epsilon catalytic subunit A (POLE) gene plays a crucial role in DNA repair and chromosomal replication.

Researchers from The University of Osaka find that chronic liver congestion is linked to severe liver diseases through a specific signaling pathway in liver sinusoidal endothelial cells - key cells lining the liver's tiny blood vessels.

Congenital aniridia is a rare disease caused, in most cases, by mutations in the PAX6 gene, which is essential for the development of ocular structures.

A new study suggests that pancreatic cancer may start preparing to "hide" from the immune system long before the disease becomes full-blown cancer.

Terminal ileum intubation is considered the completion step of colonoscopy and is usually performed to assess the ileum.

Research indicates that peanut butter can enhance muscle power in older adults, but its impact on overall physical function and gait speed is limited.

Findings indicate zero-alcohol advertising could serve as indirect marketing for alcohol, raising questions about its impact on adolescent drinking behaviors.

As people age, they experience a gradual decline in intrinsic capacity (IC), the combined physical and mental abilities that support independence and health. The World Health Organization recognizes IC as a central indicator of resilience in aging, yet no affordable, validated tool exists to measure it.

Breasts are necessary for breastfeeding, but their size is not decisive in terms of milk production. A large part of the breast consists of adipose tissue, and earlier theories have suggested that they function, for example, as a body fat reserve. Another theory proposes that breasts evolved through sexual selection as a signal of individual fitness, similar to facial symmetry.
