Microbes Capable of Surviving Harsh, Mars-Like Conditions Discovered
2012-06-09 05:58:05

Soil samples obtained from South American volcanoes have revealed a smattering of different microbe types that have somehow managed to survive in extreme conditions, the University of Colorado-Boulder (CU-Boulder) announced in a June 8 press release. According to the university, the scientists behind the research discovered bacteria, fungi, and a different type of simple organism known as archaea living in conditions similar to Mars -- a landscape which they dub "some of the most...

Humans spend greater than 90 percent of their time indoors, but we're never alone there. Bacteria and viruses, scientists estimate, make up half of the world's biomass–some 10 nonillion (1 followed by 31 zeros) microorganisms–and we most often meet them within enclosed spaces. So, that's where the modern microbe hunter often looks first. A new report issued by the National Institute of Standards and Technology (NIST) offers guidance to make the hunting more effective. A...

Nowhere To Hide: Bacteria Behind The Eardrum Seen with New Device
2012-05-30 08:37:02

Doctors can now get a peek behind the eardrum to better diagnose and treat chronic ear infections, thanks to a new medical imaging device invented by University of Illinois researchers. The device could usher in a new suite of non-invasive, 3-D diagnostic imaging tools for primary-care physicians. The research team, led by University of Illinois electrical and computer engineering professor Stephen Boppart, will publish their advance in the online Early Edition of the journal Proceedings...

Queen Of Spades Key To New Evolutionary Hypothesis

Microscopic ocean plankton mimic card also known as the Black Queen Sleight of hand is a trait that belongs mainly to humans. Or so scientists thought. Studies of common, microscopic ocean plankton named Prochlorococcus show that humans aren't the only ones who can play a mean game of cards. Their method lurks in the Black Queen Hypothesis, as it's called, after the Queen of Spades in the card game Hearts. Scientists Jeffrey Morris and Richard Lenski of Michigan State...

Infants whose gut is colonised by E. coli bacteria early in life have a higher number of memory B cells in their blood, reveals a study of infants carried out at the Sahlgrenska Academy at the University of Gothenburg, Sweden. The bacteria in our gut outnumber the cells in our bodies by a factor of ten and are extremely important for our health because they stimulate the maturation of the immune system. The normal bacterial flora in the gut is established at the very beginning of our...

Whilst some bacteria can provide health benefits there are others that can do annoying things — like kill you. So in order to save ourselves we should probably kill them first. So, stand aside bacterial wipes, hand sanitizers and antiseptic sprays there is a new bug zapper in town. Bring in the plasma flashlight — a torch that emits a plasma jet that kills bacteria on the skin in an instant. Developed by a group of Chinese and Australian scientists, including CSIRO, the...

A new hypothesis counters popular evolutionary thinking that living organisms evolve by adding genes rather than discarding them A new hypothesis posed by a University of Tennessee, Knoxville, associate professor and colleagues could be a game changer in the evolution arena. The hypothesis suggests some species are surviving by discarding genes and depending on other species to play their hand. The groundbreaking "Black Queen Hypothesis" got its name from the game of Hearts. In...

Microorganisms play pivotal functions in nature, particularly within aquatic ecosystems. Whether in an ocean or a lake, they are key players in the food chain and the vitality of individual ecosystems. A team of researchers led by Arezoo M. Ardekani, the Rev. John Cardinal O'Hara, C.S.C., Assistant Professor of Aerospace and Mechanical Engineering at the University of Notre Dame, has shown that density stratification, a frequent feature of aquatic environments, has important ecological...
