Study: Earth's carbon points to planetary smashup

A study by Rice University researchers proposes that the origin of Earth's volatile elements, including carbon, can be explained by a massive collision between Earth and an embryonic planet similar to Mercury. This collision may have led to the exclusion of carbon from Earth's core and its incorporation into the silicate mantle.

Warmer, wetter climate would impair California grasslands

A new study reveals that warmer, wetter climate conditions in California would impair grassland productivity. The research found that average conditions from the past 40 years are near optimal for grass production, and any significant deviation toward warmer or wetter conditions will cause land to be less productive.
