Envisat captures first image of Sargassum from space

...now combining data from MERIS with a sophisticated processing algorithm and powerful Grid computing to broaden this new view. The basic principle behind Grid computing is that anything one computer can do, a pool of computers can do faster and better, enabling the solution of massively complex tasks beyond the ...

Brain holds clues to bipolar disorder

...ties in the neural systems that underlie emotional processing and cognitive control unique to the bipolar brain. Such abnormalities are valuable biomarkers for the illness and have the potential to help clinicians diagnose bipolar disorder earlier and more efficiently. Dr. Phillips also will present data illust...

CT scan reveals ancient long-necked gliding reptile

...gle slice contained the entire skeleton. Post-scan processing produced an amazingly clear, if somewhat flattened, image of a small reptile with a long neck and swept back wings. Gliding behavior evolved several times in reptiles and is present in the Indonesian reptile Draco. ...

Putting feelings into words produces therapeutic effects in the brain

...as also been implicated in inhibiting behavior and processing emotions, but exactly what it contributes has not ...Lieberman said. “We typically think of language processing in the left side of the brain; however, this effect was occurring only in this one region, on the ri...

How the brain's backup system compensates for stroke

...healthy cortical networks can flexibly reconfigure processing in a way that is rapid, functionally-specific, and preserves behavior." ...

Traumas like Sept. 11 make brains more reactive to fear

...rauma has been found to make the brain's emotional processing centers -- particularly the amygdalae, the parts of the brain that judge emotional intensity and make emotional memories -- more sensitive in cases of PTSD. The findings suggest that events that trigger shock, fear and horror that are within a norm...

Brain's white matter -- More 'talkative' than once thought

...eans of cell-to-cell communication and information processing in the gray matter. The phenomenon was unlikely, they said, because in the mouse brain, OPCs in the myelin-rich white matter are far from synapses, the points of contact between nerves where glutamate is released. Theorizing that OPCs might have ...

New technique will produce a better chromosome map

...cells, and the application of computer-based image processing to analyze hundreds of examples of the same chromosomes. With so many crisp images to analyze, computer algorithms can accurately calculate the number, shape and location of the chromosome bands. "Two researchers might see the same image different...

New bacteria test could improve quality of fruit and vegetable juice

.... Lin said that testing time is critical for juice processing companies, which monitor for the bacteria during the processing and final product stage. He said the DNA technique in combination with infrared spectroscopy techniq...

Magnetic computer sensors may help study biomolecules

...gnificant milestone for applications. Parallel processing of single biomolecules would be a significant advance over existing techniques limited to studying one molecule at a time. Optical tweezers, which use lasers to trap and manipulate biomolecules, tend to be slow and limited in force, and the particles...

DOE JGI sets 'gold standard' for metagenomic data analysis

...llowed us to quantify the fidelity of several data processing methods, since we could identify the correct answer by comparing the synthetic datasets to the corresponding isolate genomes." "This paper provides an extremely useful survey of tools and existing approaches for metagenome analysis and points out ...

Dinosaur hearing, listening to muscle noise, quieter cubicles

...e with very good sound quality using modern signal processing techniques. As an illustrative demonstration, Fitz will transform some of the "world's worst sounds" (as determined by UK acoustician Trevor Cox, http://www.sound101.org/ ) into more pleasing (or at least entertaining) ones. Morphing is often appli...

Get a whiff of this: Smell test could sniff out serious health problems

...ess neurological machinery in the brain devoted to processing the sense of smell. “So, that’s the reason it might be acting a little bit like the canary in the mineshaft. Because it’s more fragile, when you have insult to the brain, it may be sensitive to loss earlier in the disease process.? Frank adds that ...

Noise echoes in cell communications

...loit randomness for important processes of sensory processing and cell to cell communication. In terms of hearing, the Rutgers-Camden research team's mathematical theory improves previous knowledge by offering a single explanation of the properties of noise in hearing under different conditions. To develop ...

Blood sugar's manufacture limited by building blocks' supply

...s known as gluconeogenesis, due to a defect in the processing of amino acids. Amino acids are the main ingredients of proteins and the source of a key substrate in blood sugar's production. "Gluconeogenesis is a complicated process," said Mukesh K. Jain of Case Western Reserve University. "It fundamentally r...

Common gene version optimizes thinking -- but with a possible downside

...formation from multiple brain chemical systems for processing by the cortex. Both the neurotransmitter that it works through, dopamine, and the chromosomal site of its gene have been implicated in schizophrenia. "Although several groups have looked for possible clinical relevance of DARPP-32, they have not ...

Research finds music training 'tunes' human auditory system

...ought to be unchangeable and uninvolved in complex processing -- and the neocortex, a higher order brain structure associated with music, language and other complex processing. These findings are in line with previous studies by Wong and his group suggesting that musical experience can improve one’s ability...

Wired for sound: How the brain senses visual illusions

...ry flash was also marked by a rapid enhancement of processing in the auditory cortex of the brain. By observing the auditory boost, the researchers could predict when subjects would report seeing the visual illusion of a second flash. "Our results provide evidence that perception of the illusory second fl...

Study shows hope for early diagnosis of Alzheimer's

...e of late life.? The researchers employed signal processing and automated neural network analysis of event related potentials (ERPs) of the EEG signals, monitoring how the patients?brains reacted to a series of auditory stimuli. Clark’s team conducted neuropsychological tests, including memory tests, of re...

Using brain scans, researchers find evidence for a two-stage model of human perceptual learning

...al prefrontal cortex, were found to be active when processing the images. "The lateral prefrontal cortex is known to be the center of cognitive control," Riesenhuber said. "That is where the brain connects physical input to an action or response, deciding what task to do and how to respond to a stimulus." In...
