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.

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.

Using relatively new methods in astronomy, the researchers were able to identify the most precise ages currently possible for a sample of about a hundred red giant stars in the galaxy.

Researchers have developed an innovative way to convert plastics to ingredients for jet fuel and other valuable products, making it easier and more cost effective to reuse plastics. The researchers in their reaction were able to convert 90% of plastic to jet fuel and other valuable hydrocarbon products within an hour at moderate temperatures and to easily fine-tune the process to create the products that they want.

Global land use more extensive than estimated
Humans leave their 'footprints' on the land area all around the globe. These land-use changes play an important role for nutrition, climate, and biodiversity. Scientists have now combined satellite data with statistics from the past 60 years and found that global land-use changes affect about 32 percent of the land area. This means that they are about four times as extensive as previously estimated.

Evolutionary biologists discover mechanism that enables lizards to breathe underwater
A team of evolutionary biologists has shown that Anolis lizards, or anoles, are able to breathe underwater with the aid of a bubble clinging to their snouts. Some anoles are stream specialists, and these semi-aquatic species frequently dive underwater to avoid predators, where they can remain submerged for as long as 18 minutes. The researchers termed the process 'rebreathing' after the scuba-diving technology.
