The interior of Greenland (seen here with researchers’ tents pitched) is usually covered in frozen ice and snow. In July 2012, though, 97 percent of the surface melted for the first time in more than 100 years. Scientists now know why that happened.

Pulling Water Out of the Ground May Lead to Quakes on the San Andreas Fault

Ground movements linked to water extraction may change stresses on the fault famously responsible for California earthquakes

In her seminal rose diagram, Florence Nightingale demonstrated that far more soldiers died from preventable epidemic diseases (blue) than from wounds inflicted on the battlefield (red) or other causes (black) during the Crimean War (1853-56). “She did this with a very specific purpose of driving through all sorts of military reforms in military hospitals subsequent to the Crimean War," says Kieniewicz.

Bees from a single species aren't as effective in pollinating as bees from a diversity of species, a new study shows.

New Research

A Diversity of Bees Is Good for Farming—And Farmers’ Wallets

A new study shows that if more species of bees are available to pollinate blueberry flowers, blueberries get fatter

Around three billion people worldwide depend on rice for their diet. But a new study finds that rice and other crops grown under high levels of atmospheric carbon dioxide results in lower levels of some nutrients.

New Research

More Carbon Dioxide in the Air Makes Some Crops Less Nutritious

Crops such as rice and wheat have lower concentrations of some nutrients when they’re grown under an atmosphere with higher levels of the greenhouse gas
