Letters from the Feb. 7, 2004, issue of Science News.
Warm topic I was fascinated by the article on heat production in flowers (“Warm-Blooded Plants?” SN: 12/13/03, p. 379: Warm-Blooded Plants?). It speculated on the evolutionary origins of such thermogenesis and observed how it predominates in ancient lineages of flowering plants like magnolias and water lilies. But thermogenesis goes back much farther than this, for […]

Wine Surprise: Heart-protective effect is independent of antioxidants
Two studies in mice suggest that, if wine protects against heart disease, it's probably not because of the antioxidants that the drink contains.
