by Gillian Rutherford, University of Alberta Credit: Pixabay/CC0 Public Domain Female astronauts could avoid knee injuries during space flight—and better tests, prevention and treatments could be developed for knee osteoarthritis in women here on Earth—based on newly published research on the sex differences in knee meniscus tissue. Knee osteoarthritis is more common in females than...
by Michael Morrison, Massachusetts General Hospital Credit: Pixabay/CC0 Public Domain Spontaneous coronary artery dissection (SCAD), a tear in an artery supplying blood to the heart, is a common cause of serious or fatal heart attacks that occur in women under age 50. Although the cause of SCAD is unknown, risk factors include female sex, recent childbirth, irregular...

Technique allows researchers to toggle on individual genes that regulate cell growth, development and function. By combining CRISPR technology with a protein designed with artificial intelligence, it is possible to awaken individual dormant genes by disabling the chemical “off switches” that silence them. Researchers from the University of Washington School of Medicine in Seattle describe...
Chemists tend to think of the human body as operating out of a sense-and-respond paradigm. For example, you eat sugar, the pancreas senses the intake, and it responds by releasing the hormone insulin to keep your glucose levels in check. Scientists have long wondered whether there is a similar regulatory strategy for clearing other metabolites, like amino...
