Recharging Old Eggs
Infertility is often due to poor egg quality, or chromosomal damage. Some of this damage may occur in the egg's mitochondria, the cell's powerhouse. A new procedure seeks to replace mitochondria in old eggs with fresher mitochondria to improve egg quality. However, some doctors say there haven't been enough studies to know if the procedure is either safe or …
Gender Diversity in Basic Research
Only about a third of research subjects in clinical studies are women. In basic research on animals and cells, female models are even more poorly represented. This results in poor understanding of how new drugs work on women and occasional drug recalls when major side effects are discovered after the fact. Experts discuss why such an imbalance occurs, its …
Stem Cell Regeneration
Scientists have discovered that older research animals can seemingly be made young again with infusions of young blood which reactivate stem cells. Researchers have started to isolate factors in plasma that appear to be responsible, opening the door to possibly rolling back the clock on aging. Experts explain.
The Power of Tears
Researchers are learning that tears shed for different reasons are chemically different. Emotional tears, for example, contain high levels of stress hormones, indicating they may be a way for the body to reduce stress.
Preserving Life Versus Prolonging Death
An award winning science writer discusses her experience observing how medical professionals and patients differ in their acceptance of impending death, and what families need to know to navigate the end of life toward a "good death."
Distracted Teen Drivers
Teenage drivers are the most dangerous on the road. Graduated driver's license programs have improved their record, but a new study finds teen drivers are often distracted before crashes. Brain biology plays a role. Experts discuss distracted driving and ways to get teens to pay attention on the road.
Infant Sleep and Shaken Babies
New parents are often at wits' end when their baby won't sleep. Infants who won't sleep and cry inconsolably are also at major risk of being victims of shaken baby syndrome.
The Gut Microbiome
Scientists are learning that the bacteria living inside us, most notably in the intestines, influence our bodies far more than previously suspected. Our microbiome influences many other organs, particularly the liver, brain, and immune system. Different mixes of these bacteria may account for a great deal of the variability among people, particularly in our …
