tap-water-glassResearchers at the Fraunhofer Institute have used a quantum cascade laser, a particular type of infrared laser, in analysis equipment that can automatically test samples of drinking water for contaminants. This technology analyzes water samples at the waterworks itself, and it needs only a couple of minutes to determine whether water contains any impurities and… »

osu-tse-tse-flyResearchers at the Oregon State University (OSU) have devised innovative approach that could reduce or even eliminate the deadly disease African trypanosomiasis (sleeping sickness), which was shown in a recent mathematical modeling study. They developed genetic-modification strategies to reduce the transmission of sleeping sickness, but this method appears as a promising strategy for reducing the… »

stacey-liang-1Most of legume species, plants in the family Fabaceae (Leguminosae), live in symbiotic relationships with nitrogen-fixing bacteria (rhizobia bacteria). The bacteria receive food from plant, and in turn the bacteria fix the nitrogen that most plants need to grow green and healthy. Researchers at the University of Missouri have found that nonlegumes plants respond to… »

photocatalytic-diskA group of researchers at National Taiwan University, National Applied Research Laboratories in Taiwan, and the Research Center for Applied Sciences in Taiwan have found a potential novel use for old music CDs. They coated disks with zink oxide (ZnO) nanorods that can function as a photocatalyst, a substance which can promote the reaction without… »

Using ‘wired microbes’ to generate electricity from sewage

23 September 2013

microbial-battery-1Exoelectrogenic microbes are organisms evolved in airless environments which developed the ability to react with oxide minerals to create biological fuel needed for their survival. Although several research groups tried different approaches to tap into this source of energy since the turn of millennium, efficient use of these microbes as bio-generators proved to be challenging…. »

First real-time detector for intravenously delivered drugs

One Comment22 September 2013

first-real-time-detector-for-intravenouslyCurrently, computerized automated systems deliver drugs intravenously in exact volumes to hospital patients. However, these intravenous (IV) drug delivery systems cannot recognize which medications are in the tubing nor can they determine the concentration of the drug. A group of electrical and computer engineering students at the University of Illinois at Urbana-Champaign (UIUC) have developed… »
