Plants and stress -- key players on the thin line between life and death revealed
08-01-2007 · EurekAlert!
Scientists from VIB, associated with the K. U. Leuven, have revealed a mechanism demonstrating the ways in which plants deal with stress. The discovered control system has a remarkable way of orchestrating activity of hundreds of genes, forcing the plant into "safety mode." This may have negative impact on growth, but allows the plant to temporarily safeguard itself against stress conditions. These findings also may prove to be valuable in understanding disorders such as cancer and diabetes.

'Erectile dysfunction' drugs heighten natural anti-cancer activity
12-07-2006 · EurekAlert!
Sildenafil and other "impotence drugs" that boost the production of a gassy chemical messenger to dilate blood vessels and produce an erection now also show promise in unmasking cancer cells so that the immune system can recognize and attack them, say scientists at the Johns Hopkins Kimmel Cancer Center.

UC San Diego researchers give computers 'common sense'
10-17-2007 · EurekAlert!
Using a little-known Google Labs widget, computer scientists from UC San Diego and UCLA have brought common sense to an automated image labeling system. This common sense is the ability to use context to help identify objects in photographs. For example, if a conventional automated object identifier labels a person, a tennis racket, a tennis court and a lemon in a photo, the new post-processing context check will re-label the lemon a tennis ball.

Plant pathogen yields substance to fight neuroblastoma
01-17-2008 · EurekAlert!
Drug treatment of neuroblastoma, a tumor of the nervous system in children, poses major problems. Therefore, scientists at the German Cancer Research Center have been searching for substances that are suitable as a basis for developing better drugs. Now they have found a candidate: HC-toxin, which is isolated from a fungal plant pathogen. The substance from the maize pathogen reprograms neuroblastoma cells in such a way that they behave almost like healthy cells again.

Detailed 3-D image catches a key regulator of neural stem cell differentiation in action
12-07-2006 · EurekAlert!
Researchers at the Salk Institute for Biological Studies in collaboration with scientists at the University of California, San Diego took a high resolution "action shot" of a protein switch that plays a crucial role in the development of the nervous system. Their findings, published in the December 8 issue of the journal Molecular Cell, provide a template for the design of small molecule inhibitors to control that switch, a protein called Scp1, at will.

Scientists work to deep-six carbon dioxide
02-07-2007 · Massachusetts Institute of Technology (MIT)
A new analysis led by an MIT scientist describes a mechanism for capturing carbon dioxide emissions from a power plant and injecting the gas into the ground, where it would be trapped naturally as tiny bubbles and safely stored in briny porous rock.

Protecting US crops from terrorist attack to be discussed at 2007 AAAS Annual Meeting
02-18-2007 · EurekAlert!
A sound and safe agricultural system is critical to national security, but are US crops, a cornerstone of our nation's economy, vulnerable to attack? The latest information on strategies currently in place and what is still needed to keep US crops safe from terrorist attack will be presented by Jacqueline Fletcher, Sarkeys Distinguished Professor of Plant Pathology at Oklahoma State University, during the 2007 American Association for the Advancement of Science (AAAS) Annual Meeting in San Francisco, Calif.

West Antarctic to be covered with scientific instruments; network to watch through dark polar night
12-10-2007 · EurekAlert!
In a mission of unprecedented scale, scientists are about to cover West Antarctica with a network of sensors to monitor the interactions between the ice and the earth below -- 24 hours a day, 365 days a year. The National Science Foundation just awarded the collaboration, called POLENET, $4.5 million to plant global positioning system trackers and seismic sensors on the bedrock that cradles the West Antarctic Ice Sheet.

Yogi Berra supposedly suggested that when you come to a fork in the road, you are supposed to take it.That's just what planetary scientists studying the rich data set from the Galileo Mission to the outer solar system are doing now. They're taking the fork.William B. McKinnon, Ph.D., professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, says the community suffers from an embarrassment of riches

Researchers show how obesity causes breakdown in system which regulates appetite and weight
03-06-2007 · EurekAlert!
Research led by scientists at the Oregon National Primate Research Center demonstrates how obesity causes the breakdown of a brain system that regulates appetite. Specifically, the scientists determined that leptin resistance prevented a portion of the brain called the arcuate nucleus from taking part in an important signaling function that regulates appetite and body weight.
