Human gene number increases

...rk. According to the researchers, gene-prediction algorithms are at fault, rather than the underlying sequence itself. Cooke says that computational methods, which look for similarities to known gene sequences, are difficult to get right. The final number will remain unknown until firm biological evidence, suc...

An Eye Opener for the blind

...puter-imaging technology, including edge-detection algorithms to simplify the image. The computer then triggers a second microcomputer that transmits pulses to an array of 68 platinum electrodes implanted on the surface of the brain's visual cortex. Bringing wires through the skin without discomfort or infe...

A new replacement

...r which is attached to the probe uses mathematical algorithms to analyse the data and classifies the tissue as healthy, pre-cancerous or cancerous.Unlike the PAP smear which aims to scrape cells from the cervice. Each year 300 women in Australia and hundreds of thousands of women around the world die from cerv...

Heart Patients More At Risk Get Fewer Medicines

...se of quantitative multifactorial risk profiles or algorithms that convey information regarding probability of poor outcomes could be applied to better identify such patients. Source: Newswise...

Detecting Epidemics using statistics

...ased MIDAS researchers will test complex detection algorithms thereby looking for outbreaks of resistant pathogens that may be regional or national in scope. The researchers have three areas to concentrate such as model specification, which gives the number of people using the health care services. Model bui...

Bioinformatics Made a Boon In Immune Response Study - LIAI Finds

...le bioinformatics – which uses computer databases, algorithms and statistical techniques to analyze biological information -- is already in use as a predictor of immune response, the LIAI research team's findings were significant because they demonstrated an extremely high rate of prediction accuracy (95 percen...

Genetic Variation: We're More Different than We Thought

...much variation exists, Scherer said. "Our computer algorithms are smart, but it is hard to find something if it is not there in the reference you are comparing against." In fact, Scherer's group found some 30 million nucleotides that are seemingly not yet represented at all, or in different copy numbers or or...

In Search of Truth - 'Lie Detector

... The scrolling paper has found a substitute in the algorithms and computerized monitor. Recent technological advances have help invent ‘lie detecting’ gadgets with an LSD display that are the size of one’s palm. These gadgets help to measure variations in a person’s voice that would indicate if the person is d...

Scientists Map Key Landmarks in Human Genome

...s involved processing the data using computational algorithms devised by Dana-Farber faculty member X. Shirley Liu, PhD, and her postdoctoral fellow Jun S. Song, PhD, working closely with Fisher's graduate student Fatih Ozsolak. The researchers borrowed a computational technique from signal processing called "w...

Rhode Island Biotechnology Company Develops Tularemia Vaccine

...mes for candidate vaccine components with computer algorithms is at the core of this research effort,” said Anne De Groot, M.D., President and CEO of EpiVax. “These study results highlight the ability of our computer-aided vaccine design (VaccineCAD) approach to create effective and innovative vaccines at an ac...

Master Switches Found for Adult Blood Stem Cells

...ith a custom-built, computer software program. Its algorithms let the software, fed data from samples of blood and bone marrow from healthy donors, match RNA pairs. The outcome was a core set of 33 microRNAs that match with more than 1,200 of the larger variety RNA already known to be important for stem-cell ma...

New Cardiovascular Risk Prediction Models Developed for Women

Computer Software Less Reliable Than Radiologists' Eyes in Detecting Cancerous Tumors

...s, according to a study. CAD systems use complex algorithms to identify "suspicious" areas of a mammogram for a radiologist to review. The systems, which cost $50,000 to $175,000, were approved by FDA in 1998 and are sold by several companies, the New York Times reports. Medicare gives providers extra $20 ...

Life Functions Governed by Circadian Rhythms-new Research

...ave failed, the Colorado State study uses advanced algorithms that have the capacity to identify patterns in such a large number of genes. Ptitsyn discovered that gene activity oscillates in a "finely orchestrated" system and gene expression can be impacted by daylight and darkness -- or a lack of both. For e...
