A novel bioremediation technology for cleaning up per- and polyfluoroalkyl substances, or PFAS, chemical pollutants that threaten human health and ecosystem sustainability, has been developed by Texas A&M AgriLife researchers. The material has potential for commercial application for disposing of PFAS, also known as “forever chemicals.”

Published July 28 in Nature Communications, the research was a collaboration of Susie Dai, Ph.D., associate professor in the Texas A&M Department of Plant Pathology and Microbiology, and Joshua Yuan, Ph.D., chair and professor in Washington University in St...

The damaging effects of daily, lifelong exposure to the blue light emanating from phones, computers and household fixtures worsen as a person ages, new research by Oregon State University suggests.

The study, published today in Nature Partner Journals Aging, involved Drosophila melanogaster, the common fruit fly, an important model organism because of the cellular and developmental mechanisms it shares with other animals and humans.

Jaga Giebultowicz, a researcher in the OSU College of Science who studies biological clocks, led a collaboration that examined the survival rate of flies kept in darkness and then moved at progressively older ages to an environment of constant blue light from light-emitting diodes, or LEDs.

The darkness-to-light transitions occurred at the ages of...

Researchers have identified a gene that promotes muscle strength when switched on by physical activity, unlocking the potential for the development of therapeutic treatments to mimic some of the benefits of working out.

Published in Cell Metabolism, the University of Melbourne-led study showed how different types of exercise change the molecules in our muscles, resulting in the discovery of the new C18ORF25 gene that is activated with all types of exercise and responsible for promoting muscle strength. Animals without C18ORF25 have poor exercise performance and weaker muscles.

Project lead Dr Benjamin Parker said by activating the C18ORF25 gene, the research team could see muscles become much stronger, without them becoming necessarily bigger.

“Identifying this gene may impac...

A single chemical is key to controlling when hair follicle cells divide, and when they die. This discovery could not only treat baldness, but ultimately speed wound healing because follicles are a source of stem cells.

Most cells in the human body have a specific form and function determined during embryonic development that does not change. For example, a blood cell cannot turn into a nerve cell, or vice versa. Stem cells, however, are like the blank tiles in a game of Scrabble; they can turn into other types of cells.

Their adaptability makes them useful ...
