454 sequencing identifies HIV drug resistance at early stage

...ds of thousands of long clonal sequence reads that accurately enable the sensitive detection of rare mutations” explained Egholm Michael, Ph.D. vice president of research and development at 454 Life Sciences. “Ultra Deep Sequencing provides an essential tool for research on viral diseases and their treatments....

Scientists close in on missing carbon sink

...lying on ground-level measurements, they failed to accurately simulate the movement of carbon dioxide vertically in the atmosphere. The models tended to move too much carbon dioxide toward ground level in the summer, when growing trees and other plants take in the gas, and not enough carbon dioxide up in the wi...

Want to save polar bears? Follow the ice

...GIS) map that will enable conservationists to more accurately predict where sea ice—a vital habitat for polar bears and seals that they prey on—will remain into the near future. "The polar bear could be at the crossroads," said Scott Bergen, a landscape ecologist with WCS’ Living Landscapes Program and the ...

'Virtual Patient' to simulate real-time organ motions for radiation therapy

...P-Man will allow doctors and medical physicists to accurately predict and monitor these anatomical changes to provide the most effective treatment possible at any given time," Xu said. The fourth dimension of the VIP-Man is not easily achieved, according to Xu. Currently Xu and De are focusing their energy o...

Cancer patients monitor fatigue in real time

...ut it's difficult for health care professionals to accurately assess its severity. Nurse researchers at the University of Illinois at Chicago are studying fatigue in cancer patients undergoing stem cell transplants using a method successfully used to monitor behaviors such as smoking cessation and alcohol use....

New technique will produce a better chromosome map

...y 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 differently," said graduate research assistant Mert Dikmen, who uses computer vision technologies under the supervision of Beckman Institut...

New bacteria test could improve quality of fruit and vegetable juice

Decoding protein structures helps illuminate cause of diabetes

...able of measuring molecular structures quickly and accurately enough to catch moving proteins in mid-fold and see the shapes of intermediate steps. As described in this week's online issue of the Proceedings of the National Academy of Sciences, the first applications of the technique offer a glimpse into the c...

BMI not accurate indicator of body fat

...found that in most cases the student's BMI did not accurately reflect his or her percentage of body fat. The research is published in the March issue of Medicine and Science in Sports and Medicine, the official journal of the American College of Sports Medicine. BMI is determined by this equation: A perso...

Beyond the DNA: Chemical signatures reveal genetic switches in the genome

...r, says Heintzman, this 'histone code' was able to accurately distinguish between promoters, from which gene transcription is directly initiated, and enhancer regions - some of which are very distant from the target gene - to which transcription-activating cofactors bind. According to LICR's Dr. Bing Ren, t...

Navigable nanotransport

To accurately transport pharmaceutical agents to their specific target organs or cell types, you need a good carrier: nanoscopic capsules with surface elements that can "recognize" the target in question could do the trick. To date, all methods for the production...

Major gene study uncovers secrets of leukemia

...ons, since not every gene in this pathway could be accurately analyzed using this methodology," Downing said. The mutations identified in "PAX5," "EBF" and "Ikaros" are likely to directly contribute to this block in normal lymphocyte differentiation, according to Downing. These genes encode proteins called ...

FSU researchers determine a critical factor in workings of proteins

...versity researchers' new theory has been proven to accurately predict the association rate for proteins. Their t...laq put forth a new theory that has been proven to accurately predict the association rate for proteins by developing a theoretical model for the association proc...

Racing neurons control whether we stop or go

...hether a movement is made or not. Though the model accurately explains behavior, it left neuroscientists scratching their heads. Their work found that "go" and "stop" processes are produced through a complex network of interacting neurons. If so, then how could "go" and "stop?be acting independently as required...

Computer imaging assists with facial reconstructive surgery

... article. It is essential for plastic surgeons to accurately analyze the face before surgery so that afterward, prominent facial features such as the chin and nose are balanced in relation to the structures around them. “Even a well-executed surgery will result in a poor aesthetic result if inaccurate analysi...

Biologists produce global map of plant biodiversity

...on environmental data, the scientists were able to accurately capture the factors that promote high species richness of plants. "This allowed us to estimate the richness of yet unsurveyed parts of the world," says Jetz. "The global map of estimated plant species richness highlights areas of particular conce...

Speeding 'fingertip' discovery -- 20 years of protein info in 1 place

... the original goal of the research was to identify accurately as many protein changes as possible using the new technology. “But to see how well we measured up, we had to compare our findings to what already was published, and there was just no clean, easy way of doing that because there were reports all over t...
