What do scientists know about vitamin D and cancer?

We know vitamin D is good for us — it helps keep our bones strong and supports our immune system.  But some 42 percent of the U.S. population doesn’t get enough of the sunshine vitamin.

Scientists discover new information about cell death, previously believed to be irreversible

A study published by researchers at the University of Illinois Chicago describes a new method for analyzing pyroptosis — the process of cell death that is usually caused by infections and results in excess inflammation in the body — and shows that process, long thought to be irreversible once initiated, can in fact be halted…
