Researchers Discover That Microbes Can Produce Miniature Electrical Wires

...monstrated promise as cleaners of toxic spills and generators of energy. They are anaerobic bacteria (living without oxygen) that use metals to gain energy the way humans and other organisms use oxygen. They are distributed throughout the world in a wide variety of soils and sediments. Geobacter have been used ...

Protein structure key for AIDS, cell function

...ions of times more intense than conventional X-ray generators allow. The very intense beams were necessary to determine the atomic structure of CD38. The research group, which includes researchers from the University of Minnesota, also developed new calculations that allowed them to extract the protein's entire...

New discovery blurs distinction between human cells and those of bacteria

...d organelles, such as mitochondria, the tiny power generators in cells. Cells of prokaryotes have been viewed as very primitive, although some contain unusual enclosures known as microcompartments, which appear to serve as primitive organelles inside bacterial cells, carrying out special reactions in their inte...

Nighttime Dying Linked To Sleep Apnea From Brain Cell Loss

Many cleaners, air fresheners may pose health risks when used indoors

...s done. Also, people should avoid the use of ozone generators or ionizing air cleaners, especially in the same space where terpene-containing cleaning products or air fresheners are being used. The report is an important milestone that highlights the need to investigate potential health effects of ultrafine pa...

Squid-inspired design could mean better handling of underwater vehicles

...er has designed a new generation of compact vortex generators that could make it easier for scientists to maneuv...a widespread problem." Mohseni created his new generators after studying the formation of vortex rings, much like those formed by squid and jellyfish to move ...

Implanting dopamine generators in brain cells obtains improvement in Parkinson's in monkeys

Implanting dopamine generators (dopaminergics) in brain cells has produced improvement in the symptoms in Parkinson's, according to the results of tests carried out with monkeys by the Navarra University Hospital, led by Dr María Rosario Luquin Piudo, neurologist at the Hospital a...
