'Might have been' key in evaluating behavior
05-14-2007 · EurekAlert!"What might have been" or fictive learning affects the brain and plays an important role in the choices individuals make -- and may play a role in addiction, said Baylor College of Medicine researchers and others in a report that appears online today in the Proceedings of the National Academy of Sciences.

- Drive-by-wire and human behavior systems key to Virginia Tech's Urban Challenge vehicle
08-10-2007 · EurekAlert!
Virginia Tech's entry in DARPA's Urban Challenge is moving forward to the qualifying rounds, thanks in part to a custom-designed drive-by-wire control system and unique navigation software that makes the vehicle's driving decisions almost human. "VictorTango," a team of Virginia Tech engineering and geography students, is among 36 semi-finalists selected by Defense Advanced Research Projects Agency to vie for the $2 million Urban Challenge prize.

- Emerging field of neuroecology is showcased in December issue of the Biological Bulletin
12-14-2007 · EurekAlert!
Neuroecology bridges a critical gap between studying the neural basis of behavior (neuroethology) and evaluating the consequences of that behavior at the ecological levels of populations and communities. Richard K. Zimmer of UCLA and Charles D. Derby of Georgia State University have organized a "virtual symposium" of leading-edge research in neuroecology for the December issue of the Biological Bulletin, published by the Marine Biological Laboratory in Woods Hole, Mass.

- Old memory traces in brain may trigger chronic pain
06-04-2007 · EurekAlert!
A Northwestern University researcher has found a key source of chronic pain appears to be an old memory trace that essentially gets stuck in the prefrontal cortex, the site of emotion and learning. The researcher has identified a drug that controls persistent nerve pain by targeting the part of the brain that experiences the emotional suffering of pain. The drug is D-Cycloserine, which has been used to treat phobic behavior over the past decade.

- Study finds drug spending caps cause some seniors to quit taking key medicines
09-11-2007 · EurekAlert!
Many seniors quit taking drugs for chronic illnesses such as diabetes and high blood pressure when they exceed their drug plan's yearly spending limits, according to a RAND Corp. study. The report, which examines the behavior of seniors enrolled in a private health plan, provides insight into how seniors may act under provisions of Medicare's new drug benefit plan that will leave about one-third of enrollees without drug coverage for some part of each benefit year.

- New method edges closer to holy grail of modern chemistry
10-12-2006 · EurekAlert!
University of Chicago chemist David Mazziotti has developed a new method for determining the behavior of electrons in atoms and molecules, a key ingredient in predicting chemical properties and reactions. He presented the details of his method in the Oct. 6 issue of the journal Physical Review Letters. "In his new paper, David Mazziotti has made a major advance in fundamental theory," said Nobel laureate Dudley Herschbach of Harvard University.

- Researchers at IRB Barcelona discover a new mechanism that regulates stem cell division
03-05-2007 · EurekAlert!
Stem cells have the extraordinary capacity to divide producing two very distinct cells: one retains stem cell identity and continues to undergo asymmetric division, while the other specializes for a specific function and shows limited capacity to divide. This strategy allows a single stem cell to generate great amounts of tissue during a lifetime. Researchers at IRB Barcelona, have discovered that one of the key factors in asymmetric stem cell division is the behavior of centrosome.

- Fighting like a girl or boy determined by gene in fruit flies
11-19-2006 · EurekAlert!
Fighting like a girl or fighting like a boy is hardwired into fruit fly neurons, according to a study in the November 19 Nature Neuroscience advance online publication by a research team from Harvard Medical School and the Institute of Molecular Pathology in Vienna. The results confirm that a gene known as "fruitless" is a key factor underlying sexual differences in behavior.

- Children's perceptions of their parents' antisocial behavior may lead them to be antisocial
02-07-2007 · EurekAlert!
A recent study to examine how antisocial behavior is transmitted across generations found that children's perceptions of their parents' behavior may be key in the development of these behaviors. Researchers looked at 430 adolescents and their biological parents across the child's high school years. The findings reflect that since parent behavior gives children a model for their own behavior, perceiving that a parent is antisocial may give a child permission to engage in similar behaviors.

- Scientists zero in on the cellular machinery that enables neurons to fire
11-14-2007 · EurekAlert!
If you ever had a set of Micronauts -- toy robots with removable body parts -- you probably had fun swapping their heads, imagining how it would affect their behavior. Scientists supported by the National Institutes of Health have been performing similar experiments on ion channels -- pores in our nerve cells -- to sort out the channels' key functional parts.

- Staying out of jams
07-23-2007 · EurekAlert!
What do sand, cereal, ice cubes, gravel, sugar, pills, and powders have in common? They are members of an unruly family of substances that refuse to completely conform to the laws of behavior for either solids or liquids -- much to the consternation of theoretical physicists and manufacturers alike. Whether it's a huge grain silo, a coal hopper or a pharmaceutical manufacturing plant, being able to predict the behavior of dense granular packings is key to keeping things from jamming up or collapsing.
