Green tea´s ability to fight cancer is even more potent and varied than scientists suspected, say researchers who have discovered that chemicals in green tea shut down one of the key molecules that tobacco relies upon to cause cancer. It´s a find that could help explain why people who drink green tea are less likely to develop cancer.

The finding by scientists at the University of Rochester´s Environmental Health Science Center appears in the July 21 issue of Chemical Research in Toxicology

University of Michigan Kellogg Eye Center scientists have been studying a family whose members have an eye disease that looks like age-related macular degeneration (AMD), but that has a rarer pattern of inheritance that results in an exceptionally high incidence of the disease among family members in the study.

In the August issue of Investigative Ophthalmology & Visual Science (IOVS), Kellogg scientist Radha Ayyagari, Ph.D., and her collaborators from the U-M and other institutions identify

Much has been written about the glass ceiling, the double standard and other barriers to women in management. A related question that has consumed both academic and popular writers is whether men and women have the same leadership abilities.

The answer suggested by a comprehensive meta-analysis published in the current Psychological Bulletin (Vol. 129, No. 3) might surprise you. On average, women in management positions are somewhat better leaders than men in equivalent positions, according

This is clearly Europe´s time for interplanetary exploration. Having sent the first European mission to Mars, ESA is about to launch its first probe to the Moon. It is called SMART-1 and its goals are both technological and scientific. It is the first of a series of “Small Missions for Advanced Research in Technology”.

On the one hand, SMART-1 will test new state-of-the art instruments and techniques essential to ambitious future interplanetary missions, such as a solar-electric prim

Water churns through diversion holes in the world’s largest dam – China’s Three Gorges project on the Yangtze River, imaged here by ESA’s Proba satellite this week. Seen to the left, the waters behind the dam have risen to a level of 135 metres since the sluice gates were first closed in early June, and in August Three Gorges is due to generate its first commercial hydroelectricity.

The Three Gorges project is set to create a new 600-km-long body of water on the face of the 21st century Ea

A study of 137 new product launches in 16 European countries shows the persistence of major regional disparity in the era of the European Union, according to an article in a journal of the Institute for Operations Research and the Management Sciences (INFORMS®).

“While we expected some differences, we were surprised by the size of the differences,” the authors write. “We were also surprised by the fact that Scandinavian countries tend to have the shortest `time-to-takeoff´ of all E
