Researchers at the Salk Institute for Biological Studies have gone beyond manipulating adult stem cells cultured in the lab and achieved the same feat with adult neural stem cells - still in place in the brain. They successfully coaxed mouse brain stem cells bound to join the neuronal network to differentiate into support cells instead.

The discovery not only attests to the versatility of neural stem cells but also opens up new directions for the treatment of neurological diseases, such as multiple sclerosis, stroke and epilepsy that not only affect neuronal cells but also disrupt the functioning of glial support cells.

Throughout life, adult neural stem cells generate new brain cells in two small areas of mammalian brains: the olfactory bulb, which processes odors, and the dentate gyrus, the central part of the hippocampus, which is involved in the formation of memories and learning.

A laser-activated antimicrobial offers hope for new treatments of bacterial infections, even those that are resistant to current drugs. Research published today in the open access journal BMC Microbiology describes the use of a dye, indocyanine green, which produces bacteria-killing chemicals when lit by a specific kind of laser light.

Michael Wilson led a team from UCL (University College London) who carried out experiments showing that activated indocyanine green is capable of killing a wide range of bacteria including Staphylococcus aureus, Streptococcus pyogenes and Pseudomonas aeruginosa. The dye is safe for humans. The strength of this new approach lies in the variety of ways in which the chemicals produced by the activated dye harm bacteria.

Sol Invictus, Iowa State University's student-designed and student-built solar race car, is getting ready to compete in the North American Solar Challenge July 13-22.

The challenge will take 24 student-designed and student-built solar race cars from Plano, Texas, to Calgary, Alberta, Canada. They’ll make the 2,400-mile run July 13-22, with a checkpoint in Omaha, Neb., July 15-16 and a stage stop in Sioux Falls, S.D., July 16-18. The route between those cities takes the solar cars into western Iowa for a few hours.

Team PrISUm did very well in 2005, the last time the challenge was contested. The Iowa State car made it from Austin, Texas, to Calgary in 71.5 hours. That was good for a third place finish in the challenge’s stock class and 11th overall against cars in the more powerful open class.

The "La Mente Bilingüe" research team headed by Itziar Laka leads at the University of the Basque Country aims to find out how the brain acquires and manages languages and to discover in what way languages being similar or different is influential in this process.

In order to understand how we become fluent in a language and to better comprehend bilingualism, the La Mente Bilingüe ("the bilingual brain") research team at the Faculty of Arts of the University of the Basque Country UPV/EHU analysed the acquisition process for languages.

Despite much research on acquisition of languages amongst monolingual persons, scientists still have to ask themselves basic questions about bilingual acquisition: How do babies realize that they are in a bilingual environment? What are the clues for them in discovering this? How is discrimination between languages produced in infants?

KARLSRUHE, Germany, June 30 /PRNewswire/ -- RapidSolution Software AG presents new Windows software MP3videoraptor 3.0 that allows users to instantly download and save virtually any song in MP3 format - free of charge. Even the automatic creation of an entire music library is a piece of cake.

What makes this principle revolutionary are two functions: an intelligent control and the recording of music from numerous individual Web 2.0 radios - the legal and free way to get your favorite music.

If you're in one of those municipalities that would rather ban foods than learn science, you probably aren't allowed to have food with trans fats in a restaurant.

That's because, they say, trans fat lowers “good” HDL cholesterol and raises the “bad” LDL variety - but that's not true for the kind normally present in meat and dairy products and those are not a big health concern, reports the July 2008 issue of the Harvard Health Letter.

Hydrogenation, the process used to convert oil into solid trans fat by adding hydrogen, occurs in nature also. Bacteria in animals’ stomachs hydrogenate the fatty oils from animal feed, for example.
