James "Jim" Stewart--the chief diving officer emeritus at the Scripps Institution of Oceanography and the so-called "father" of the U.S. Antarctic Program's diving program--died in Irvine, California on June 7 at the age of 89. Stewart adapted the scientific-diving best practices that he helped develop for the American Academy of Underwater Sciences to produce guidelines for the U.S. Arctic and Antarctic programs, procedures still used to this day.

Paleontologists uncovered the fossil remnants of the oldest forest yet discovered in Antarctica. At about 270 million years old, the fossils come from an extinct species of tree known as Glossopteris. The fossils promise to offer paleontologists insights into the prehistoric climate and ecology of Antarctica, and the dramatic ecological changes that were about to sweep across the continent.

The history of the East Antarctic Ice Sheet is written in stones along the Transantarctic Mountains. Over the past two years, researchers ventured to remote areas along the mountain range to decipher how high ancient glaciers reached, by studying the rocks they left behind. By measuring the amount of cosmic radiation the rocks have been exposed to, the research team can map out the reach of ancient glaciers at different points in the past.
