What about other benchmarks used by experts? There are no federal limits on the amount of lead that dietary supplements may contain. But the FDA does publish something it calls an “interim reference level”—a guideline for reducing the potential adverse effects of dietary lead exposure—which is 8.8 micrograms per day for women of childbearing age,…
Researchers from the Leonardo da Vinci DNA Project (LDVP) report that by analyzing the drawing of Holy Child and other Renaissance artifacts, such as letters written by a da Vinci relative, they have recovered some Y chromosome DNA sequences that appear to belong to a genetic group of people with common ancestors in Tuscany, where…
