When seeking a physician, you should look for one with experience. Right? Maybe not. Research on physicians' decision-making processes has revealed that those who pay attention to failures as well as successes become more adept at selecting the correct treatment. "We found that all the physicians in the study included irrelevant criteria in their decisions," said Read Montague, Ph.D., director of the Human Neuroimaging Laboratory at the Virginia Tech Carilion Research Institute...

Creating new, improved pharmaceuticals is sometimes very similar to cracking the code of a combination lock. If you have the wrong numbers, the lock won´t open. Even worse, you don´t know if your numbers are close to the actual code or way off the mark. The only solution is to simply guess a new combination and try again. Similarly, when a newly created drug doesn´t bind well to its intended target, the drug won´t work. Scientists are then forced to go back to the lab,...

Image 1 - Bats Can Change Ear Shape To Make Their Hearing More Flexible

"Certain bats can deform the shapes of their ears in a way that changes the animal's ultrasonic hearing pattern. Within just one tenth of a second, these bats are able to change their outer ear shapes from one extreme configuration to another," said Rolf Müller, associate professor of mechanical engineering at Virginia Tech. Müller and his students wrote a paper on their work that is appearing this week in Physical Review Letters, a prestigious peer-reviewed...

For decades, scientists and farmers have attempted to understand how a bacterial pathogen continues to damage tomatoes despite numerous agricultural attempts to control its spread. Pseudomonas syringae pv. tomato is the causative agent of bacterial speck disease of tomato (Solanum lycopersicum), a disease that occurs worldwide and causes severe reduction in fruit yield and quality, particularly during cold and wet springs. In the spring of 2010, for example, an outbreak in Florida and...

A research team led by investigators at the Virginia Tech Carilion Research Institute has demonstrated the first rapid measurements of dopamine release in a human brain and provided preliminary evidence that the neurotransmitter can be tracked in its movement between brain cells while a subject expresses decision-making behavior. "In an experiment where we measured dopamine release while a subject made investment decisions in a stock market trading game, we showed that dopamine tracks...

Bed Bug Insecticide Resistance Mechanisms Identified
2011-10-20 08:22:01

Bed bugs, largely absent in the U.S. since the 1950s, have returned with a hungry vengeance in the last decade in all 50 states. These insects have developed resistance to pyrethroids, one of the very few classes of insecticide used for their control. A research team at Virginia Tech has discovered some of the genetic mechanisms for the bed bug's resistance to two of the most popular pyrethroids -- deltamethrin and beta-cyfluthrin. The discoveries will accelerate efforts to understand the...

Virginia Tech released today results from the first study ever to instrument child football helmets. Youth football helmets are currently designed to the same standards as adult helmets, even though little is known about how child football players impact their heads. This is the first study to investigate the head impact characteristics in youth football, and will greatly enhance the development of improved helmets specifically designed for children. The Auburn Eagles, a local, Montgomery...

(Ivanhoe Newswire) — Youth football helmets are currently designed the same as adult helmets, even though it isn´t known how child football players impact their heads. This novel study conducted at Virginia Tech investigates the head impact characteristics in youth football, and will greatly enhance the development of improved helmets specifically designed for children. The Auburn Eagles, a Montgomery County, Virginia youth team consisting of 6 to 8 year old boys, has...
