University of Minnesota receives NSF grant to sequence legume genome

... usable form, and packing legumes with protein and figure out ways to make them work better." Of special interest is the way legumes and the bacteria that infect their roots "tell" each other who they are. Such communication is essential for the two organisms to recognize each other and take the next step...

Grant of powerful computer to Rutgers-Newark will increase understanding of brain activity

...ber-crunching and more time looking at the data to figure out why the brain is using certain areas in conjunction with others to accomplish things. The new combined supercomputing cluster also means that scientists can better isolate and look more closely at portions of the brain called Brodmann's areas, wh...

Hand-to-ear link in brain established after minutes of piano learning

...n: "The 'no-map' group was not given any chance to figure out any coupling between fingers and notes, except the temporal coincidence of keystroke and sound. In other words: these subjects were not given any opportunity to establish an internal 'map' between motor events and auditory pitch targets." Before...

Sleep boosts ability to learn language, University of Chicago researchers find

...e word more than once, so they had to learn how to figure out the pattern of sounds the synthesizer was making. "It is something like learning how to understand someone speaking with a foreign accent." Nusbaum said. The team tested three groups of students. The control group was tested one hour after the...

Roderick MacKinnon wins 2003 Nobel Prize in Chemistry

... several years for MacKinnon and his colleagues to figure out which amino acids actually formed the tunnel through which the ions passed. By using a technique called site-directed mutagenesis--painstakingly altering the protein by one amino acid at a time to determine the effects of such changes--MacKinnon'...

... any case, it's virtually certain that in order to figure out how to treat this disease, you must understand the mechanism," said Goldstein. "You must understand which cells you need to replace. And I believe that this study represents an important step toward that goal."...

Princeton paleontologist produces evidence for new theory on dinosaur extinction

...eller. These views have not made Keller a popular figure at meteorite impact meetings. "For a long time she's been in a very uncomfortable minority," said Vincent Courtillot, a geological physicist at Universit Paris 7. The view that there was anything more than a single impact at work in the mass extincti...

Researchers solve the mystery of a key structure in immune system cells

... their next phase of research, Dr. Dustin hopes to figure out just what causes T-cell receptors to be degraded. In this process, the receptors are pulled inside of the cell, and sorted according to their signaling history: If they were part of intense signaling, they're degraded, but if not, they're returne...

Cellular problem discovered behind syndrome of obesity, learning disabilities

...eral population. Katsanis says the next step is to figure out exactly what is wrong with the cilia and how those problems affect different tissues. The problems could lie in cilia's movement or in their ability to sense cells' surroundings. "Cilia are very overlooked," says Katsanis, whose laboratory has un...

New pollutant cleanup technique puzzles, pleases chemists

...orks so well, but we'll take it and develop it and figure out the details as we go," Gerald Meyer, professor of chemistry in the Krieger School of Arts and Sciences at The Johns Hopkins University, said with a laugh. The targets of the new technique, developed by Sherine Obare, a postdoctoral fellow in Meye...

...e. It's a unique molecular mechanism. We'd like to figure out how that happens chemically and exactly how this interaction occurs." Along with Marzluff and Dominski, UNC co-authors include Xiao-cui Yang and Handan Kaygun. Co-author Dr. Michael Dadlez is from Warsaw University in Poland.Support for the resea...

Emory scientists track down immune sentinel cells with gene gun

... vaccines, Dr. Jacob notes. "Usually, you have to figure out how to grow a virus, then inactivate it so that it doesn't actually cause an infection. This new methodology could take advantage of the immunizing capabilities of abundant, long-lived dendritic cells."...

Trawlers threaten ocean's biodiversity

... pristine seamounts. Once fished by trawlers, that figure drops to 5 per cent, and the seamount loses half its biomass. And recovery is painfully slow. Some seamounts in the north Pacific have still not bounced back 50 years after boats first trawled them, says John Dower, a fisheries oceanographer at the ...

How AIDS destroys immunity

...V killed white blood cells, but it took a while to figure out how," Planelles says. "We don't know it completely yet. But by 1995, we figured out that the vpr gene was major factor in killing the cells. In fact, we can use vpr alone in the absence of other HIV DNA [genetic material] or proteins to kill whit...

Hopkins is first US institution to obtain powerful genotyping system

...to the fine detail of very small regions of DNA to figure out what's really happening," says Scott. With the appropriate controls and experimental set-up by trained technicians, the system determines the genotypes of all the samples and produces a score that rates the accuracy of the result. "These genotype...
