Research aimed at understanding how lice feed off humans may lead to new methods to control the blood-sucking pest that can transmit fatal diseases.
Genetic research conducted by Purdue researcher Barry Pittendrigh may "ultimately lead to some real long-term benefits for Indiana and throughout the world," according to the assistant professor of entomology.

In the November issue of the journal Insect Biochemistry & Molecular Biology, Purdue and Harvard university researchers report finding lice genes that control the breakdown of their human blood meal into energy and waste. They also identified the first gene in lice that may impact the insects ability to fight off bacterial infections. The study is currently on the journals Web site.
"This research eventually may lead to long-term human health benefits for people throughout the world," said Barry Pittendrigh, assistant professor of entomology and senior author of the study. "We need to develop novel strategies for controlling these pests. Body lice raise significant health concerns in developing countries, and head lice afflict children in North America and elsewhere."

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
