U-M scientists find new genetic marker for prostate cancer
...cause prostate cancer, but they can be a marker or indicator of prostate cancer for diagnostic or prognostic purposes. AMACRs accuracy and specificity is a major improvement over the Prostate Specific Antigen (PSA) test the only diagnostic screening test currently available to physicians. The beauty of AMACR ...Biological evidence can persuade people to change unhealthy habits

For example, in one study, patients informed of their carbon monoxide levels (resulting from smoking) and genetic susceptibility for lung cancer were twice as likely to at......action. Since subcellular localization is a strong indicator of protein function, Dr. Snyder and colleagues developed a high-throughput method to tag individual proteins and visualize their movements within living cells. Dr. Snyder and colleagues successfully determined the subcellular localization of over 270...Tent caterpillars and their parasites

...egetation cover varies with rainfall, it is a good indicator of climate variability, and therefore of conditions necessary for disease outbreaks. "So far, our team has mapped areas of Africa at risk for RVF outbreaks," Anyamba said. "Satellite mapping has identified where and when RVF outbreaks will occur." ...Satellites vs. mosquitoes: Tracking West Nile Virus in the U.S.

Satellites let researchers see which areas have these conditions, allowing for better prediction of disease transmission. Similarly, satellites also he...Scans link 2 key pieces of schizophrenia puzzle

.... Tactile clues are probably the most reliable indicator of zooplankton density at this scale. A right whale could use the whiskers on the front of its head for detection of individual zooplankton organisms. There is much that remains unknown about the migratory and foraging strategies of right whales,...The influence of disturbance on tropical rain forest biodiversity: End of a controversy in sight

He points out that, by ignoring leap year, climate experts have inadvertently allowed statistical bias to creep into their analyses, resulting in false estimates of springs actual arrival. "A number of international studies have s...Women more susceptible to orthostatic hypotension

An analysis of the find, forthcoming in the December issue of the Journal of Human Evolution, argues that this ancient use of bone tool technology, together with related discoveries, has strong implications that...New research identifies why men and women may differ in food choices
