The masterpieces that spring from the talents of Rembrandt, Van Gogh and other artists often begin with the creation of a gradient of colors on a palette. In a similar manner, researchers at the National Institute of Standards and Technology have created an innovative device called the “microflu... Read More
Many of the new techniques based on nanotechnology that have been developed for faster and more sensitive detection of pathogens fail in day-to-day clinical use because they require complex sample preparation or measurement equipment, or simply cannot keep up with the large sample throughput in ...

Bacteria found in sweet gum wood may improve the preprocessing steps for cost-effective production of cellulosic ethanol.
JDR-2, a strain of the wood-decaying bacteria Paenibacillus, can break down and digest hemicelluloses, which in traditional cellulosic ethanol production is broken down by... Read More
