Brain-mapping technique aids understanding of sleep, wakefulness
The power of a new technique to map connections among nerve cells in the brain has a UT Southwestern Medical Center scientist dreaming of solving the mysteries of sleep. By tracking which nerve cells in the mouse brain stimulate others, researchers in Japan and at UT Southwestern found that a type of neuron responsible for keeping animals awake receives inhibitory signals from neurons act...Wake Forest scientists find new combination vaccine effective against plague
Plague, a bacterium that ravaged Europe in the Middle Ages and is today one of the most feared potential agents of bio-terrorism, may have met its match, according to Wake Forest University School of Medicine scientists. Steven B. Mizel, Ph.D., principal investigator, told the American Gastroenterological Association meeting in Chicago that when mice immunized with a new combination vaccin...Freeze-dried mats of microbes awaken in Antarctic streambed
An experiment in a dry Antarctic stream channel has shown that a carpet of freeze-dried microbes that lay dormant for two decades sprang to life one day after water was diverted into it, said a University of Colorado at Boulder researcher. The results showed the resilience of life in the harsh polar environment, where temperatures are below freezing for most of the year and glacial...Health of Acehnese reefs in the wake of the tsunami shows human impacts more harmful
According to research reported this week in Current Biology, tsunami damage to coral reefs closest to the epicenter of the 2004 Sumatra-Andaman earthquake was occasionally spectacular, but surprisingly limited, particularly when compared to damage from chronic human misuse in the region. Less than 100 days after the tsunami of December 26, 2004, a team of ecologists from James Cook Univer...New mechanism explains glucose effect on wakefulness
One of the body's basic survival mechanisms is the neural machinery that triggers the hungry brain to the alertness needed for seeking food. That same machinery swings the other way after a hearty meal, as exemplified by the long and honored custom of the siesta. However, scientists have understood little about how the basic energy molecule, glucose, regulates such wakefulness and other energy-re...Merge president steps down in wake of shareholder suits

CHICAGO This column isnt just for Midwestern technology job seekers. Its also for all Midwestern technology folks. Why have we concentrated so hard on job seekers here? Because so many of us are job hunting? That's only part of the reason. More than that, it's because theres so much to say on the subject of Midwestern technology job hunting. So many things to know. So many angles to tr...Wake-up call for peripheral artery disease
Peripheral artery disease is underdiagnosed and treated in many cases, say US doctors. In peripheral artery disease (PAD), the arteries in the legs and arms become blocked with the same kind of fatty deposits - plaque - which cause coronary artery disease. The best way of treating it is very simple - keep walking. While the disease makes walking painful, regular exercise does actually inc...Awakening call for fall prevention
According to Orthopaedic researchers, it is important that older people escape falls, because fracture treatment may be slow and complex. As people age, they are more likely to have a fall because// of decreased agility and an overall decline in general health. And since an older person's bones are often thinner, treatment is difficult and healing slow. American Academy of Orthopaedic...Besides keeping you awake for exams coffee boosts memory as well!
There is another feather in the coffee cap proposed by a study by Florian Koppelstatter, University Hospital Innsbruck & colleagues which says that drinking a cup of coffee with 100 mg caffeine can boost short-term memory.// The sample and procedure for the study involved 15 healthy men aged 26 to 47. Participants were tested when they consumed 100 mg caffeine and then when they consumed...Time to wake up as conservationists
Its time we took note and took care of mother nature. A program aimed towards this goal is underway in USA.It is called the Canon National Parks Science Scholars // Program. It currently inducts its ninth class with eight doctoral students -- from Canada to Chile, and from Florida to Ohio,Illinois and Georgia. These chosen few are receiving significant multi-year scholarships this year to...
