Spanish scientists have described the lichen Phylloblastia fortuita, new to the Iberian Peninsula and to science. Another species from the same family, Phylloblastia dispersa, is also a new entry for Europe and is the first time it has been found outside the tropics. Foliicolous lichens, symbiosis between fungi and algae, are organisms associated with tropical or sub-tropical climates, and their presence in environments such as the Iberian Peninsula, outside of the tropics, is associated with...

Ancient soil biota decreased in size by up to 46 percent during period 55 million years ago Ancient soil-inhabiting creatures decreased in body size by nearly half in response to a period of boosted carbon dioxide levels and higher temperatures, scientists have discovered. The researchers' findings were published in the October 5, 2009, early online edition of the journal Proceedings of the National Academy of Sciences (PNAS). Jon Smith, a scientist at the Kansas Geological Survey, and...

Lichen study has implications for ecosystem researchLichens are the classic example of a symbiotic relationship. Both the fungal and photobiont components of the lichen benefit from the relationship and often are unable to survive without each other. Recent research by Dr. Robert Lcking (The Field Museum, Chicago), Dr. James Lawrey (George Mason University, Virginia) and a team of colleagues from around the world has put a new spin on this relationship.In a paper published in the August 2009...

 A Kansas State University researcher is studying the potential health benefits of a specially bred purple sweet potato because its dominant purple color results in an increased amount of anti-cancer components.K-State's Soyoung Lim, doctoral student in human nutrition, Manhattan, is working with George Wang, associate professor of human nutrition at K-State, to understand the pigment effects of a Kansas-bred purple sweet potato on cancer prevention.Lim said purple sweet potatoes have...

U.S. and British scientists have developed a cleaning protocol for space hardware that could be used on missions to other planets. The protocol was developed as part of a project to investigate life that exists in extreme Arctic environments, which are the closest analogue on Earth to the surface of Mars. The protocol, developed and tested by scientists at the University of Leeds and the National Aeronautics and Space Administration, deals with the dilemma known as forward contamination --...

"What you see is what you get" often is the mantra in the highly competitive life of birds, as they use brilliant displays of color to woo females for mating. Now researchers are finding that carotenoids -- the compounds responsible for amping up red, orange, and yellow colors of birds -- also may play a role in color perception and in a bird's ability to reproduce, making it a cornerstone in birds' vitality. These are among the findings presented by Kevin McGraw, an Arizona State University...

Black raspberries not only taste delicious, and now scientists say they may also help ward off cancer. A study by the Ohio State Comprehensive Center revealed black raspberries contain the cancer fighting agent known as anthocyanins, a class of flavonoids that inhibit the growth of esophageal cancer in rats. "Our data provide strong evidence that anthocyanins are important for cancer prevention," Gary D. Stoner, Ph.D., a professor in the department of internal medicine at Ohio State...

Anthocyanins, a class of flavonoids in black raspberries, inhibited cancer growth in the esophagus of rats, U.S. researchers said. Gary D. Stoner of the Ohio State Comprehensive Cancer Center fed rats an anthocyanin-rich extract of black raspberries and found that the extract was nearly as effective in preventing esophageal cancer in rats as whole black raspberries containing the same concentration of anthocyanins. This study demonstrates the importance of anthocyanins as preventive agents...

A study published in Cancer Prevention Research, a journal of the American Association for Cancer Research, identifies components of black raspberries with chemopreventive potential.Researchers at the Ohio State Comprehensive Cancer Center found that anthocyanins, a class of flavonoids in black raspberries, inhibited growth and stimulated apoptosis in the esophagus of rats treated with an esophageal carcinogen."Our data provide strong evidence that anthocyanins are important for cancer...

British scientists say they expressed two genes from snapdragon to induce the production of anthocyanins -- protective against cancers -- in tomatoes. Cathie Martin of the Norwich BioScience Institutes in England said anthocyanins are naturally occurring pigments found at particularly high levels in berries such as blackberry, cranberry and chokeberry that offer protection against certain cancers, cardiovascular disease and age-related degenerative disease. "Most people do not eat five...
