Organic vs Conventional Meat and Milk

Two recently published meta-analyses, one on meat and another on milk, conclude that levels of polyunsaturated fatty acids (PUFA) and omega-3 fatty acids are higher in the organic versions of both.

Zika virus, microcephaly, and calls to bring back DDT (Rachel Carson revisionism edition)

Curse Removal from the Annals. More Acupuncture Nonsense.
