What Makes The Brain Tick, Tick, Tick: Researchers Gaining New Insights Into Brain's Internal Clock

...s of how this timing process works, with constant, parallel input from throughout the brain." In such studies, the researchers face the daunting process of trying to monitor the intricate swirling of neural activity throughout the entire brain, said Meck. "Looking at only one place in the brain for the inter...

Neurotransmitters signal aggressive cancer, offer potential for early diagnosis

...e in tumors is. They combined the mouse data with parallel data from 182 human tumors. Then, the gene-activity data was fed into sophisticated software that supplied the researchers with a prediction about which metabolic reactions were revved up in the tumors and which were slowed down. The last piece of th...

Evolution of life on Earth may hold key to finding life in outer space

...ch type of extremophile found, animators created a parallel imaginary alien planet on which these microbes are likely to thrive rather than just survive, allowing audiences to explore the types of alien worlds where scientists may one day find real alien life. "All known living organisms on Earth share vario...

Elderly mice yield clues to the process of growing old

...cience report, markers of oxidative stress did not parallel the accumulation of mitochondrial genetic mutations. Instead, the group found evidence that indicated accelerated cell death, especially in tissues characterized by rapid turnover of cells, occurred as mutations mounted in the mitochondrial DNA. "We...

3D Atlas Will Help Navigate The Spinal Cord

...ntal sections, reproduce these in 3D and make some parallel observations in the human spinal cord (when tissue becomes available), thus supporting both experimental and clinical approaches. ...

UNC computer, marine scientists collaborate to predict flow of toxic waters from Katrina

...aign. Using NCSA's Xeon system, a state-of-the-art parallel computer called Tungsten, the researchers were able to complete the required computational runs in about 15 hours, from midnight on Sept. 11 to mid-afternoon on Sept. 12. "This is a prelude to the capabilities RENCI and the University of North Carol...

Woods Hole Research Center plans controlled burn in Amazon rainforest

...the forest floor using kerosene drip torches along parallel 1000m-long transects every 50 meters through the square-kilometer parcels, and allowed to spread through the forest naturally. Firebreaks are cleared along perimeter trails and roads in preparation for the event, and swept clear of debris immediately...

Motor transport in bio-nano systems

... same direction. Such an arrangement provides many parallel tracks for the molecular motors and, thus, represents a multi-lane highway in the nanoregime. Using such a biomimetic model system, scientists can study the transport properties in a quantitative manner, identify useful control parameters, and determ...

Study Finds Moderate Hypothermia A Safe Treatment For Traumatic Brain Injury In Kids

...re. An additional 27 patients were entered into a parallel trial of those patients who were excluded because there was a delay in transfer of greater than six hours following injury but within 24 hours of admission, or unknown time when the injury occurred (i.e. child abuse) or were an adolescent (13-18 year...

Unique library of plant genes germinates, takes root at UNC

... it was condensed into a few short weeks by use of parallel computing, Vision said. Currently, scientists know the complete genetic makeup of only a handful of plants although humans are economically dependent on dozens of different ones, he said. It would be far too expensive and time-consuming, however, to...

$5.1 billion would save 6 million children

...rapeutic services would be far more efficient than parallel delivery of each intervention separately. "The focus is on community-based resources, which decrease costs since building hospitals and other fixed resources isn't necessary. It is our hope that policymakers, donors and governments will use our pric...

A probe, not an echo

A sophisticated coding/decoding signal scheme recognizes a small "sweet spot" of the signal coming from the opposite transducer, and only that tr...

A New Species of Monkey is Discovered in Tanzania: The First in Africa for More Than 20 Years

... and Davenport became aware in October 2004 of the parallel discoveries in their two projects, the two teams then joined forces to write the article for Science. “This exciting discovery demonstrates once again how little we know about our closest living relatives, the nonhuman primates," said Russell A. Mit...

Gladstone investigators discover how resting T cells avoid HIV infection

... cellular RNA and possibly other host proteins. A parallel strategy would involve finding ways to prevent the small form of A3G from converting to the large form in the first place, during the process of T cell activation. However, notes Greene, scientists would first need to determine whether preserving the...

Canada approves marijuana-based pain spray

Sativex also significantly reduced pain-related sleep disturbance. Principal components A product resulting from the pioneering research efforts of UK-bas...

Same-Sex Mating Discovered in a Toxic Fungus

...portance as a health threat has therefore risen in parallel with the increased use of such therapies and with the worldwide HIV/AIDS pandemic. In plants and animals, sexual identity is governed by sex chromosomes. In fungi, however, sexual identity is determined by so-called "mating type loci," genes arrange...

Light therapy may combat fungal infections, new evidence suggests

...portance as a health threat has therefore risen in parallel with the increase in immunosuppressive therapies and the worldwide HIV/AIDS epidemic. Light normally inhibits mating of C. neoformans. The Duke team has now identified two genes responsible for that light response. Loss of the same genes also reduce...

Pathogen-Mimicking Vaccine As Strategy For Cancer Therapy

... in other trials. By comparing single variables in parallel we believe we can develop effective cancer vaccines in a much shorter time than the conventional approach of trying variables sequentially." The CVC has clinical research sites in Australia, Belgium, Germany, Japan, Switzerland, the UK and the USA. ...

Supercomputer Dedicated To Bioengineering, Computational Biology Installed

...nt operations per second), is a distributed-memory parallel computer. It is valued not only for its speed, but also because its 428 gigabytes of memory capacity and 20 terabytes of storage will enable researchers to solve ever larger and more sophisticated problems. "It's not always just a matter of computati...
