Pregnancies persist among women taking acne medication known to cause birth defects

A new study reports that although the number has decreased, women taking isotretinoin — an acne medication known to cause birth defects — have continued to get pregnant even after the implementation of special distribution restrictions.

For older women, just 7,500 steps a day lowers mortality

For many older women, the 10,000-step-a-day paradigm may seem daunting, but a new study suggests just 7,500 confers the same mortality-lowering benefit.

Harvard study finds cells recall their early development

Study in mice reveals that adult tissues retain a memory of which genes are activated during very early development, and that that memory can be recovered. Under certain conditions, adult cells play their developmental “movie” in a slow rewind, reactivating fetal genes. These findings have important implications for regenerative medicine and cancer research.

In health care, AI offers promise — and hype

AI is coming to a hospital near you — but it may be in the world’s remote regions that it could impact patients most. However, experts gathered at Harvard said its potential will not be realized unless it is deployed as part of broader health care solutions, not simply as a tool in search of problems.
