Lead levels in urban soil are declining but hotspots persist
Lead paint and leaded gasoline have been banned for decades, but unsafe levels of lead remain in some urban soils, a new study finds. The researchers mapped soil lead concentrations along 25 miles of streets in Durham, N.C. Though contamination generally has declined since the 1970s, soil collected near houses predating 1978 still averaged 649 milligrams of lead per kilogram of soil, well above the 400 mg/kg threshold associated with health risks to children.

Using DNA from greenhouse-grown plants representing all species and hundreds of varieties of watermelon, scientists discovered that watermelons most likely came from wild crop progenitors in northeast Africa. The study corrects a 90-year-old mistake that had previously tied watermelons to South Africa. The genetic research is consistent with newly interpreted Egyptian tomb paintings that suggest the watermelon may have been consumed in the Nile Valley as a dessert more than 4,000 years ago.

The emergency systems, which would have helped maintain the necessary cooling of the core, were destroyed by the subsequent tsunami. Because the reactor could no longer cool itself, the core overheated, resulting in a severe nuclear meltdown, the likes of which haven't been seen since the Chernobyl disaster in 1986.

Did Earth's early rise in oxygen help multicellular life evolve?
Researchers find that oxygenation of Earth's surface is key to the evolution of large, complex multicellular organisms. If cells can access oxygen, they get a big metabolic benefit. However, when oxygen is scarce, it can't diffuse very far into organisms, so there is an evolutionary incentive for multicellular organisms to be small to ensure most of their cells can still access oxygen.
