Neanderthal DNA mapped from Croatia bone fragment
Scientists report mapping over a million Neanderthal DNA blocks from a Croatia bone fragment dating 38,000 years. Analyses by Paabo Rubin and colleagues place human Neanderthal divergence around 500,000 years ago and find little interbreeding evidence. The work in Nature and Science shows 99.5 to 99.9 percent identity with modern humans.

Chocolate may help prevent clots at modest chocolate intake
A Johns Hopkins study finds dark chocolate with flavonols reduces blood clotting indicators in people consuming typical amounts. Researchers note the effect is far weaker than daily aspirin and would require several chocolate bars daily, with risks like obesity and tooth decay.
