Study links changes in global water cycle to higher temperatures

A new study takes an important step toward reconstructing a global history of water over the past 2,000 years. Using geologic and biologic evidence preserved in natural archives — including globally distributed corals, trees, ice, cave formations and sediments — the researchers showed that the global water cycle has changed during periods of higher and lower temperatures in the recent past.

Scientists Recruit New Atomic Heavyweights in Targeted Fight Against Cancer

Researchers from Berkeley Lab and Los Alamos National Laboratory have developed new methods for the large-scale production, purification, and use of the radioisotope cerium-134, which could serve as a PET imaging radiotracer for a highly targeted cancer treatment known as alpha-particle therapy.

Shape-Shifting Selenium; Abrupt Change Found Between Selenium-70 and Selenium-72

Nuclear scientists recently found that the nucleus of the radioactive isotope selenium-72 has a football-like shape. This is similar to the stable, nonradioactive isotopes of selenium, but different from the disk-like shape of radioactive selenium-70 nuclei. This finding helps explain how the interaction between protons and neutrons in nuclei leads to collective behavior.
