From soft drink cans to bones, virtually all materials are made up of heterogeneous - or dissimilar - microstructures, and researchers at Oak Ridge National Laboratory have developed a tool to better study those structures.

Relaxed mice may provide clues for treating anxiety
For over 20 million Americans suffering from excessive anxiety, anxiety-reducing prescription medications are widely employed, however long-term use is discouraged due to their somewhat addictive potential and sedating side effects.

Increased CO2 levels are mixed blessing for agriculture
A new study suggests that rising levels of carbon dioxide in the atmosphere could be a boon for agricultural crops, as this greenhouse gas helps crop plants grow and reproduce more.

Fred Hutchinson Research Center awarded $7 million grant
The Leukemia & Lymphoma Society (the Society) announced it has awarded a $7 million grant through its Specialized Center of Research (SCOR) program to Dr.

Doppler-guided fluid administration during surgery improves outcome
Duke anesthesiologists have found that a

Exercise and strength training could improve physical decline in elderly
Physically frail elderly persons who followed a physical therapy program consisting primarily of balance exercise and strength training saw a 45 percent reduction in disability after seven months, Yale researchers report in the October 3 issue of The New England Journal of Medicine.

Researchers discover genes that control regulatory functions in malaria mosquitoes
A team of scientists from the University of Georgia, using bioinformatics approaches, has discovered 35 genes that contain important regulatory peptides in Anopheles gambiae, the malaria mosquito.

Researchers find evidence that Antarctic ice stream has reversed its flow
It is virtually impossible for a river or a stream to first stop its flow and then reverse course.

Blocking enzyme found to ease anxiety without causing sedation
The trouble with most anti-anxiety drugs is that they tend to sedate, not just relax.

Dartmouth researcher Michael B. Sporn, M.D. honored for pioneering work in cancer prevention
Michael B. Sporn, M.D., the pioneering Dartmouth cancer researcher who championed the idea of stopping cancer before it starts, has been selected by the American Association for Cancer Research (AACR) and the Cancer Research Foundation of America (CRFA) to receive the inaugural award for Excellence in Cancer Prevention Research.

Not all mammals vomit -- or how to study emesis in mice
Drugs that inhibit a class of enzymes called class 4 phosphodiesterases have promise for the treatment of airway inflammatory diseases such as asthma, but their therapeutic potential has been limited by side effects of nausea and emesis (vomiting).

Nanocylinders open way to polymer electronics
A team of German and American scientists have succeeded in combining conventional organic molecules and conductive polymers to form highly symmetric, structured materials with new electronic properties.

Deciphering the genetic basis of the mosquito's senses
A team of researchers from Vanderbilt University, the University of Notre Dame and the University of Illinois at Urbana-Champaign have identified the genes that code for a special class of proteins that plays a critical role in almost every aspect of the life cycle of the mosquito Anopheles gambiae, including its ability to see, taste, touch, and smell.
