New genetic-modification approach could eliminate sleeping sickness

By Maja Bosanac
One Comment4 October 2013

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… »

Using ‘wired microbes’ to generate electricity from sewage

By Damir Beciri
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

By Maja Bosanac
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… »

One Comment15 September 2013

issus-nymph-1While there are examples of apparently ornamental cogs in the animal kingdom – such as on the shell of the cog wheel turtle or the back of the wheel bug – gears with a functional role have been elusive or rendered defunct by evolution. Scientists at the University of Cambridge have been able to reveal… »

13 September 2013

molecule-1Researchers at the University of North Carolina School of Medicine investigated have identified internal sensors that detect bacteria and trigger an alarm that signals for response from the immune system. The fidnings could lead to new therapies for septic shock – a medical condition that occurs when the immune system overreacts to a bacterial infection… »

One Comment28 July 2013

silk-implant-epilepcy-1A group of researchers at Legacy Research Institute, Oregon Health and Sciences University (OHSU) and Tufts University have developed silk implants that they have placed in the brain of laboratory rats in order to reduce the progression of epilepsy. These silky brain implants are designed to release adenosine (ADO) – a specific chemical compound which… »

Making biofuel from native Australian microscopic algae

By Maja Bosanac
One Comment26 July 2013

sbrc-pond-measurements-1Collaboration between researchers at the University of Queensland (UQ) with researchers at Germany’s Bielefeld University and Karlsruhe Institute of Technology resulted in identification of a fast-growing microscopic algae that could be used in production of cheaper and more efficient biofuel. Newly tested algae species native to Australia provide real hope for the development of commercially… »
