Live Science reports: Our “biological age,” which reflects signs of age-related decline in our cells and tissues, doesn’t steadily increase along with our chronological age. Instead, new research suggests that biological aging can accelerate during stressful events and then reverse after those events.

Elizabeth Janiak writes: Even before [U.S. District Court Judge Matthew] Kacsmaryk’s decision, existing federal regulations on mifepristone also reinforced abortion stigma.

Before mifepristone’s approval, most pregnancy terminations… Read More »
The Washington Post reports: Some of the workers received booster shots to prevent infection by common rabies, and none of them reported illness, according to their supervisor.

The… Read More »
ProPublica reports: When a stubborn pain in Nick van Terheyden’s bones would not subside, his doctor had a hunch what was wrong.
