by Max Esterhuizen, Virginia Tech Credit: Pixabay/CC0 Public Domain The pouring rain and blustery wind gusts are brutal. The crowd is bone-chillingly cold, but they don’t care. Their favorite football team is on the field. Suddenly, a player turns up the tempo, plowing full force into the opponent. Cheers erupt in the stands. The player...

The results of this study, reported...
by Jordan Newman, Texas A&M University Credit: Pixabay/CC0 Public Domain It has now been three decades since 700,000 American troops responded to the invasion of Kuwait in the first Gulf War, and more than a third of those troops still suffer from the same condition: Gulf War Illness (GWI). Previously labeled Gulf War syndrome, GWI...

by University of Houston Credit: Unsplash/CC0 Public Domain A study from the University of Houston College of Pharmacy, published in the Journal of the American Geriatrics Society, has evaluated the risk of overactive bladder (OAB) as a side effect of cholinesterase inhibitor (ChEI) drugs taken for dementia and Alzheimer’s disease. The research was based on the dissertation...

by Ana María Rodríguez, Ph.D., Baylor College of Medicine Using endothelial cell plasticity to improve fibroblast reprograming efficiency. Credit: The authors / Scott Holmes, C.M.I. Not too long ago, the idea of taking—for instance—a skin cell and transforming it into a muscle cell was unthinkable. About 10 years ago, however, revolutionary research showed that it...
Few developments have rocked the biotechnology world or generated as much buzz as the discovery of CRISPR-Cas systems, a breakthrough in gene editing recognized in 2020 with a Nobel Prize. But these systems that naturally occur in bacteria are limited because they can make only small tweaks to genes. In recent years, scientists discovered a...
Scientists have discovered a new potential treatment that has the ability to reverse antibiotic resistance in bacteria that cause conditions such as sepsis, pneumonia, and urinary tract infections. Carbapenems, such as meropenem, are a group of vital often ‘last-resort’ antibiotics used to treat serious, multi-drug resistant infections when other antibiotics, such as penicillin, have failed. But some...
