Sea Critters Rule the Clouds
Microscopic phytoplankton cultivate half the summer cloud droplets over the Southern Ocean

A study of clouds over the world's remotest ocean shows that ocean life is responsible for up to half the cloud droplets that pop in and out of existence during summer. Led by PNNL, scientists revealed how tiny natural particles given off by marine organisms nearly double cloud droplet numbers in the summer, which boosts the amount of sunlight reflected back to space.

Oxygen: Not at All Random
Rejecting random diffusion, oxygen atoms create detailed architectures in uranium dioxide, radically altering our understanding of corrosion

Whether it is an old car or a nuclear fuel canister, oxygen can cause extensive corrosion. Under certain conditions, oxygen corrodes fuel rods, creating problems during routine operations and emergency situations. Scientists at the Pacific Northwest National Laboratory, University of Chicago, and the Stanford Synchrotron Radiation Lightsource discovered that corrosion follows a different path in fuel rod's uranium dioxide.
