Findings from a new University of Kentucky College of Medicine and College of Health Sciences study add to growing evidence that resistance exercise has unique benefits for fat loss. The Department of Physiology and Center for Muscle Biology study published in the FASEB Journal found that resistance-like exercise regulates fat cell metabolism at a molecular level.

The study results in mice and humans show that in response to mechanical loading, muscle cells release particles called extracellular vesicles that give fat cells instructions to enter fat-burning mode.

Extracellular vesicles were initially understood as a way for cells to selectively eliminate proteins, lipids and RNA...

Bio-inspired, Blood-Repelling Tissue Glue could Seal Wounds Quickly

A new adhesive that mimics the sticky substance barnacles use to cling to rocks may offer a better way to treat traumatic injuries. Inspired by the sticky substance that barnacles use to cling to rocks, MIT engineers have designed a strong, biocompatible glue that can seal injured tissues and stop bleeding.

The new paste can adhere to surfaces even when they are covered with blood, and can form a tight seal within about 15 seconds of application...

Light Therapy Helps Burn Injuries Heal Faster by Triggering Growth Protein

Light therapy may accelerate the healing of burns, according to a University at Buffalo-led study. The research, published in Scientific Reports, found that photobiomodulation therapy – a form of low-dose light therapy capable of relieving pain and promoting healing and tissue regeneration – sped up recovery from burns and reduced inflammation in mice by activating endogenous TGF-beta 1, a protein that controls cell growth and division.

The findings may impact therapeutic treatments for burn injuries, which affect more than 6 million people worldwide each year, says lead investigator Praveen Arany, DDS,...

New device can diagnose COVID-19 from Saliva Samples

The tabletop diagnostic yields results in an hour and can be programmed to detect variants of the SARS-CoV-2 virus. Researchers report that the diagnostic is just as accurate as PCR tests.

Engineers at MIT and Harvard University showed that the device can also be used to detect specific viral mutations linked to some of the SARS-CoV-2 variants that are now circulating. This result can also be obtained within an hour, potentially making it much easier to track different variants of the virus, especially in regions that don’t have access to genetic sequencing facilities.

“We demonstrated that our platform can be ...
