- Biomarkers predict risk for invasive breast cancer years before the tumor develops
11-12-2007 · EurekAlert!
A team of scientists from the University of California San Francisco has identified distinct molecular markers that predict whether or not a woman is likely to develop subsequent invasive cancer after initial diagnosis with a noninvasive form of early breast cancer. The research, published by Cell Press in the November issue of Cancer Cell, provides critical information that can be used to determine whether a woman should receive more or less aggressive therapy.

- The bee that would be queen
06-05-2007 · EurekAlert!
A team of researchers from Arizona State University, Purdue University and the Norwegian University of Life Sciences has discovered evidence that honeybees have adopted a phylogenetically old molecular cascade -- TOR (target of rapamycin), linked to nutrient and energy sensing -- and put it to use in caste development. They found that queen-fate can be blocked, and that workers develop, when TOR activity is reduced during development.

- Learning how nature splits water
11-03-2006 · EurekAlert!
An international team led by scientists from the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) pieced together high-resolution (approximately 0.15 Еngstrom) structures of a Mn4Ca cluster found in a photosynthetic protein complex. Their work could help researchers synthesize molecules that mimic this catalyst, which is a central focus in the push to develop clean energy technologies that rely on sunlight to split water and form hydrogen to feed fuel cells or other non-polluting power sources.

- UF scientists reveal how dietary restriction cleans cells
08-23-2007 · EurekAlert!
Cutting calories helps rodents live longer by boosting cells' ability to recycle damaged parts so they can maintain efficient energy production, according to a University of Florida Institute on Aging study. Understanding how the process works at the cellular level in rodents could help scientists develop drugs that mimic the process in humans.

- Higher efficiency organic solar cell created by UCSB Nobel Laureate and research team
07-12-2007 · EurekAlert!
Using plastics to harvest the energy of the sun just got a significant boost in efficiency thanks to a discovery made at UC Santa Barbara. Nobel laureate and Alan Heeger, professor at UC Santa Barbara, worked with Kwanghee Lee of Korea and a team of scientists to create a new "tandem" organic solar cell with increased efficiency. The discovery, explained in the July 13 Science, marks a step forward in materials science.

- Study sheds light on why humans walk on two legs
07-23-2007 · EurekAlert!
Studying chimpanzees trained to use treadmills, a team of anthropologists have gathered new evidence suggesting that our earliest apelike ancestors started walking on two legs because it required less energy than getting around on all fours.
