Simulations unravel outer membrane transport mechanism

...ng X-ray data and advanced computer simulation and visualization software, researchers at the University of Illinois have painstakingly modeled a critical part of a mechanism by which bacteria take up large molecules. Their findings provide a rare window on the complex interplay of proteins involved in the active ...

The brain's motivation station

...lobe (MTL) of the brain. Activation prior to scene visualization suggests that the brain actually prepares in advance to filter incoming information rather than simply reacting to the world. Activation of the MTL is associated with higher brain functions, including learning and memory, and subjects who showed gre...

New tool tracks brain development in babies

...eam then applied fiber tracking to construct a 3-D visualization of the brain's white matter tracts based on the diffusion tensor images. The procedure was repeated after three months to monitor the development of the injured regions. This is the first time a group of newborns has been evaluated with fiber trackin...

Unraveling the viral mechanism

...nteract. Then as Chiu and Jiang used the computer visualization tool to strip away the surface shell entirely, they saw the concentric coil of DNA underneath. They also identified a protein "hub" through which DNA enters and exits the virus. "It's like a garden hose, in some ways," said Chiu. "You extend it. If ...

UC San Diego partners with Venter Institute to build marine microbial genomics cyberinfrastructure

CAMERA will encourage this later group to contribute their software analysis tools, thus engaging the broader community in strengt...

Stanford study of owls finds link in brain between sight and sound

...ounds originating from any direction don't require visualization to be heard. "It's exciting to find that the circuits in the brain that control gaze direction affect how the brain processes auditory information," he added. With funds from the National Institutes of Health, Winkowski and Knudsen used electrodes t...

Fruit fly's beating heart helps identify human heart disease genes

...he end of this sentence. After perfecting the new visualization technique, the researchers inserted into the fly genome a mutated gene that causes dilated cardiomyopathy in humans. This condition is often the cause of heart failure in humans and is characterized by heart muscle that has greatly enlarged and there...

Technique makes it easier to see mouse embryo in all its glory

A fast, high-resolution, 3D mouse embryo visualization technique developed by collaborators at the University of Texas Health Science Center at San Antonio and the University of Utah will revolutionize the way birth defects and cancer genes are studied in animal models. That's the prediction of the resea...
