Electrodes are inserted through stomata (small pores in the leaf surface regulating evaporation and gas exchange; dark green) into the inner leaf tissue. This way, electrical processes can be measured. Credit: Drawing: Justus Liebig University, H. Felle Using ion-selective micro-electrodes electrical signals in plants moving from leaf to leaf could be measured. The speed of [...]

Amazonian amphibian diversity traced to Andes
Study of poison frogs the first to show that the Andes Mountains have been a major source of diversity for the Amazon basin. AUSTIN, Texas—Colorful poison frogs in the Amazon owe their great diversity to ancestors that leapt into the region from the Andes Mountains several times during the last 10 million years, a new [...]

Madison, WI, March 6, 2009 — As the first plant life to emerge from the water and develop on dry earth, bryophytes offer a unique opportunity for researchers to understand the development of protections against ultraviolet radiation. The three varieties of bryophites (liverworts, hornworts, and mosses) have long been utilized as indicators of the health [...]
WASHINGTON – College women may be drinking to excess to impress their male counterparts on campuses across the country, but a new study suggests most college men are not looking for a woman to match them drink for drink. A survey of 3,616 college students at two American universities found an overwhelming majority of women [...]
BOZEMAN, Mont. — Arsenic may be tough, but scientists have found a Yellowstone National Park alga that’s tougher. The alga — a simple one-celled algae called Cyanidioschyzon — thrives in extremely toxic conditions and chemically modifies arsenic that occurs naturally around hot springs, said Tim McDermott, professor in the Department of Land Resources and Environmental [...]
Research team co-led by UC Riverside physicist observes production of single-top-quarks
posted in Headlines, SMRIVERSIDE, Calif. – A group of 28 scientists at the U.S. Department of Energy’s Fermi National Accelerator Laboratory, co-led by UC Riverside’s Ann Heinson, has made the first observation of the production of single top quarks – an observation that resulted from proton-antiproton collisions measured by the DZero detector in Fermilab’s Tevatron, the world’s highest-energy [...]
