U-M scientists say fused genes trigger the development of prostate cancer

...mosome -- so-called haplotypes -- will permit more accurate study of genetic differences and their consequences for medical research and the study of evolution. Experimental methods for deriving these haplotypes are expensive and time-consuming. But now experts in bioinformatics at two California research i...

Researchers use brain scans to predict behavior

...to the test: the volunteers knew the hint was only accurate 80 percent of the time. "Whether the hint is accurate or not was determined by the computer's random number generator, and the volunteers were not going t...

UF study first to quantify validity of DNA I.D. tool using marine snails

...ogists can identify them, the need for a quick and accurate method of classifying life has never been more pressing, Meyer said. With millions of animal species on Earth, DNA barcoding can be a helpful identification tool for ecologists who may not necessarily be taxonomy experts, he said. "This new technolo...

Researcher says flu responders can learn from 1918 epidemic

Retinal scans eyed for New Mexico show cattle

...is unique and a scan is considered one of the most accurate forms of identification, he said. The NMSU evaluations are part of an accelerating effort by the U.S. Department of Agriculture to implement a National Animal Identification System. The goal is to track and identify all animals and premises that hav...

New amphibian species result from exploration, not from rule changes

Double trouble: Cells with duplicate genomes can trigger tumors

...914, he published what Pellman calls an "amazingly accurate and prescient" treatise suggesting, among other things, that genetic instability was a cause of malignant tumors. One way to obtain this lack of chromosomal integrity, Boveri proposed, was a result of cells failing to divide normally, generating th...

Echolocation helps bats detect their surroundings, while the touch-sensitive receptors help them maintain their flight path and snag their prey. Touch receptors take the form of tiny bumps, or raised domes, along the surface of ba...

New U. of Colorado at Boulder flu chip may help combat future epidemics, pandemics

... H1N1 and H3N2. The chip was more than 90 percent accurate and will be tested again "side by side" with standard flu-virus culturing methods for accuracy and speed at the CDC's Atlanta headquarters next month. "This was the first time a version of the Flu Chip was tested outside of our lab, and it exceeded ...
