CONCORD, MASS., August 9, 2007 Every three minutes, a woman in the United States is diagnosed with breast cancer . While factors like age and heredity contribute significantly to a womans likelihood of contracting this disease, lifestyle and nutrition choices may also play a role. One dietary choice that may help provide protection against breast cancer is a glass of 100 percent grape juice mad...New test improves detection of liver cancer
Ghent, Belgium − Cancer of the liver is very difficult to detect, and it is a major cause of death in Asia and Africa, with rising incidence in Western countries as well. Now, VIB researchers connected to Ghent University, in collaboration with research centers in Beijing and Shanghai in China, have developed a test to detect liver cancer in an early stage.

Austin, TX For decades, older women have taken hormone replacements to replenish estrogen and progesterone levels lost to aging. More recently, testosterone (the most important male hormone) supplements have been used by aging men to improve their muscle mass, bone strength, libido and quality of life. In 2002, the number of elderly American men taking testosterone replacement therapy was nearl...What we can learn from the biggest extinction in the history of Earth
Approximately 250 million years ago, vast numbers of species disappeared from Earth. This mass-extinction event may hold clues to current global carbon cycle changes, according to Jonathan Payne, assistant professor of geological and environmental sciences. Payne, a paleobiologist who joined the Stanford faculty in 2005, studies the Permian-Triassic extinction and the following 4 million years o...Experiment suggests limitations to carbon dioxide 'tree banking'
