Do you hear what i see?

...University. "The textbook-standard view of sensory systems as isolated from one another is no longer tenable." Zatorre did not participate in the study. Kayser’s team used functional magnetic resonance imaging to draw a map of 11 small, tightly packed fields in the monkeys?auditory cortex that differ by t...

Pregnancy hormone key to repairing nerve cell damage

...t is thought that during pregnancy, women's immune systems no longer destroyed the myelin," said Weiss, director of the Hotchkiss Brain Institute and senior author of the study. "However, no previous study has tested whether pregnancy actually results in the production of new myelin, which may lead to improv...

Pacific Rim researchers to collaborate on distributed bioinformatics analysis of avian flu

...ational security, and current disease surveillance systems in the United States (U.S.) require an integrated computational environment to support easy access to a set of universal tools, novel algorithmic approaches and tracking mechanisms for reproducibility at a global level. Having Asian researchers i...

Ultrasound upgrade produces images that work like 3-D movies

... without goggles.) "Thousands of 3-D ultrasound systems in clinics could be upgraded with such new software, and stereoscopic goggles could be issued to them as well," Smith said. "Keepsake DVDs of the fetal exam could also be viewed at home in 3-D stereo." The goggles would soon become obsolete, he ad...

Cells use 'noise' to make cell-fate decisions

Biologically inspired sensors can augment sonar, vision system in submarines

...vement, the device can supplement sonar and vision systems in submarines and underwater robots," said Liu, who also is affiliated with the university’s Beckman Institute for Advanced Science and Technology, the Institute for Genomic Biology, and the Micro and Nanotechnology Laboratory. Liu and colleagues a...

Targeting tumors the natural way

...atural, says Kiessling. Cell recognition in living systems instead involves binding agents that attach only weakly to any single target receptor, and thus stick to cells only when several receptors are displayed together. These weak "multivalent" interactions cut down on cases of mistaken identity, because i...

Study finds mercury prevalent in many western fish

...res are not as widespread throughout western river systems as salmonids, such as rainbow and cutthroat trout, which had lower levels of mercury. Results of the study were published earlier this month in the journal Environmental Science and Technology. The researchers say the risk for humans who may oc...

Florida Tech explores microalgae for biofuel

...gae in outdoor, open settings. Cultures in outdoor systems are difficult due to the openness to light, temperature and potential contamination. Lin will manipulate dependent variables such as salinity, nutrient concentrations, pH and carbon dioxide to test optimum conditions for growth. "Alternative energy ...

Researcher examines polymers created with poultry feathers

Justin Barone, associate professor of biological systems engineering at Virginia Tech, is investigating ways to create biodegradable plastics from agricultural byproducts such as poultry feathers and eggs that would be comparable to petroleum-based plastics. He presented the research on March 29 at the 233...
