There is an appropriate time and place for employers to monitor employees, according to a business professor at the Olin Business School. If done wrong, firms can lose their worker's trust and willingness to go above and beyond.
Scientists working with diabetic mice have examined in unprecedented detail the immune cells long thought to be responsible for type 1 diabetes. They caught the immune cells, known as dendritic cells, "red-handed": they were carrying insulin and fragments of insulin-producing cells.
The duck-billed platypus: part bird, part reptile, part mammal -- and the genome to prove it. An international consortium of scientists has decoded the genome of the platypus, showing that the animal's peculiar mix of features is reflected in its DNA. An analysis of the genome, published today in the journal Nature, can help scientists piece together a more complete picture of the evolution of all mammals, including humans.
Washington University School of Medicine in St. Louis radiation oncology researchers found that tumors have a built-in mechanism that protects them from heat (hyperthermia) damage and most likely decreases the benefit of hyperthermia and radiation as a combined therapy. By interfering with that protection, the researchers have shown that tumor cells grown in culture can be made more sensitive to hyperthermia-enhanced radiation therapy.
Recent economic events have shaken the confidence of many Americans with respect to their ability to achieve the "American dream."

Rank, Ph.D., poverty expert and professor of social work at Washington University in St. Louis.
The influence of genetics increases as young women transition from their first drink to alcohol dependence. A team of researchers at the Washington University School of Medicine found that although environment is most influential in determining when drinking begins, genes play a larger role in advancing to problem drinking and alcohol dependence.
About 40 percent of African-Americans have a genetic variant that can protect them after heart failure and prolong their lives, according to research conducted at Washington University School of Medicine in St. Louis and collaborating institutions. The new study offers a reason why beta blockers don't appear to benefit some African-Americans.

Scientists estimate that there may be as few as 50 to 100 genes in human DNA that have no counterparts in other species. Little is known about the contributions these genes likely make to our species. Now scientists have produced the first analysis of a gene found only in humans and close primate relatives.

Cancer cells get a helping hand from platelets, specialized blood cells involved in clotting. Platelets shelter and feed tumor cells that stray into the bloodstream, making it easier for cancer to spread, or metastasize. Research at Washington University School of Medicine in St. Louis suggests that inactivating platelets could slow down or prevent metastasis.

A team of scientists led by Washington University in St. Louis has begun to unlock the genetic secrets of corn, a crop vital to U.S. agriculture. The researchers have completed a working draft of the corn genome, an accomplishment that should accelerate efforts to develop better crop varieties to meet society's growing demands for food, livestock feed and fuel.
Scientists at Washington University School of Medicine in St. Louis have linked a mutation in a gene known as TDP-43 to an inherited form of amyotrophic lateral sclerosis (ALS), the neurodegenerative condition often called Lou Gehrig's disease.
Critically ill patients who need a ventilator to breathe face a high risk of pneumonia. The lung infection, however, is exceedingly difficult to diagnose because a patient's underlying condition often skews laboratory test results and masks pneumonia's symptoms "“ a reality that can delay appropriate antibiotic treatment.
Former dean of the business school at Washington University in St. Louis comments on the wisdom behind the Congressional stimulus package. Stuart Greenbaum is skeptical that a stimulus package will be effective and proposes several other strategies that could improve the economy.
To overcome the genetic defect in Niemann-Pick disease, researchers at Washington University School of Medicine in St. Louis suggest that chemical compounds could "chaperone" mutant proteins to treat the rare, deadly disease. They believe this approach also could be useful for more common diseases "” such as cystic fibrosis "” that stem from a similar type of defect.
If politics were like high school, Republicans would be the football stars and Democrats would be chess club captains. Those stereotypes are the easiest way to summarize part of the conclusions made by a marketing professor at the Olin Business School at Washington University in St. Louis.
The kidney actively cleans its most selective filter to keep it from clogging with blood proteins, scientists from Washington University School of Medicine in St. Louis have revealed. Breakdown of this self-cleaning feature apparently makes kidneys more vulnerable to dysfunction and disease.

Kieff and colleagues have filed an amicus brief in the Supreme Court in support of LG.
As the number of foreclosures on homes purchased with a subprime mortgage continues to grow, politicians are focused on a way to slow, or even reverse, the trend.
