A teaspoon of dirt contains an estimated 10,000 species of bacteria, but it’s only one percent of these microbial bugs — the ones that can be grown easily in a lab — that have brought us antibiotics, anticancer agents and other useful drugs.

Researchers have discovered dental pulp stem cells can stimulate growth and generation of several types of neural cells. Findings suggest dental pulp stem cells show promise for use in cell therapy and regenerative medicine, particularly therapies associated with the central nervous system.
As concerns such as avian flu, animal welfare and consumer preferences impact the poultry industry, the reduced genetic diversity of commercial bird breeds increases their vulnerability and the industry’s ability to adapt, according to a genetics expert. Native birds however, might be able to restock poultry industry’s genetic stock.
Scientists have developed a genome-wide platform to study how specialized proteins regulate RNA in living, intact cells. The platform allows researchers to identify, in a single experiment, every sequence within every strand of RNA to which proteins bind. The result is an unbiased and unprecedented look at how differences in RNA can explain how a [...]
Crude oil is getting more and more expensive, a fact clearly felt by the chemical industry. An alternative source of carbon is biomass, for instance colza and whey, which can likewise be used to produce chemical products.
“Airport malaria” is a term coined by researchers to explain the more recent spread of malaria to areas such as the United States and Europe, which some scientists credit to warmer climate changes.

The world’s first radar breast imaging system that could revolutionize the way women are scanned for breast cancer is currently under clinical trial. Scientists have been working for a number of years to develop a breast-imaging device which uses radio waves and therefore has no radiation risk unlike conventional mammograms.

A study in rats shows that exposure to a high-fat diet during pregnancy produces permanent changes in the offspring’s brain that lead to overeating and obesity early in life. This surprising finding provides a key step toward understanding mechanisms of fetal programming involving the production of new brain cells that may help explain the increased [...]
Researchers have developed an ingenious microscopic method to observe the behavior of single nanoparticles of a catalyst, down to the resolution of single catalytic events.

Antibacterial drug use appears to have increased at academic medical centers between 2002 and 2006, driven primarily by greater use of broad-spectrum agents and the antibiotic vancomycin, according to a new article.
