AUGUSTA, Ga. -- Dissecting how heat shock protein 90 gets steroid receptors into shape to use hormones like estrogen and testosterone could lead to targeted therapies for hormone-driven cancers, such as breast and prostate, that need them as well, Medical College of Georgia researchers say.

The Magnetic Resonance Center of the University Children's Hospital Zurich has achieved a world first break through in MR-guided, non-invasive neurosurgery. Ten patients have been successfully treated by means of transcranial high-intensity focused ultrasound. This fully non-invasive procedure opens new horizons for neurosurgery and the treatment of different neurological brain disorders.

VIRGINIA KEY, Fla. -- Predation is one of the most fundamental and fascinating interactions in nature, and sharks are some of the fiercest predators on Earth. However, their hunting pattern is difficult to study because it is rarely observed in the wild. As a result, shark predatory behavior has remained much of a mystery.

BUFFALO, N.Y. -- Modern glaciers, such as those making up the Greenland and Antarctic ice sheets, are capable of undergoing periods of rapid shrinkage or retreat, according to new findings by paleoclimatologists at the University at Buffalo.

University of Georgia researchers have developed a successful way to grow molecular wire brushes that conduct electrical charges, a first step in developing biological fuel cells that could power pacemakers, cochlear implants and prosthetic limbs. The journal Chemical Science calls the technique "a significant breakthrough for nanotechnology."

Boston, MA -- As President Obama prepares to sign a bill giving the Food and Drug Administration (FDA) oversight of the tobacco industry, a new study from Harvard School of Public Health (HSPH) researchers shows that tobacco manufacturers have continually changed the ingredients and the design of their cigarettes over time, even if those changes have exceeded acceptable product variance guideli

LA JOLLA, CA, June 19, 2009 -- Researchers at The Scripps Research Institute, the University of California, San Diego, and Ohio State University have used a very sensitive fluorescence technique to find that a bacterial protein thought to exist in one "natural" three-dimensional structure (shape), can actually twist itself into a second form, depending on the protein's chemical environment.

Ca2+/calmodulin-dependent protein kinase II alpha (CaMKII alpha) is an enzyme that adds phosphates to a variety of protein substrates to modify their functions. CaMKII alpha is enriched in the hippocampus, the memory center of the brain, and is believed to be an essential mediator of activity-dependent synaptic plasticity and memory functions.

Without the process of domestication, humans would still be hunters and gatherers, and modern civilization would look very different. Fortunately, for all of us who do not relish the thought of spending our days searching for nuts and berries, early civilizations successfully cultivated many species of animals and plants found in their surroundings.
