Sports cheats beware -- new test detects previously undetectable drug

...ists have developed a method that can specifically search for the minute traces of synacthen in a blood sample. Called immunological purification, this technique can find any synacthen molecules even though its concentration is 10,000,000 less than other proteins in blood plasma. There are severe penalti...

SARS: No evidence that any of the treatments worked

... syndrome. Researchers conducted a comprehensive search for information from research studies that fitted carefully pre-defined selection criteria. They found 54 SARS treatment studies, 15 in- vitro studies, and three acute respiratory distress syndrome studies. Some of the in-vitro studies with the antiv...

Leading reason for corneal transplants comes into focus

...herited or "linked" with the disorder. Researchers search for a common location for all the linked traits until they wind up with a single chromosome address. In his latest study, Gottsch used not only linkage analysis but also a method of identifying variations in DNA sequences to examine three FCD fam...

How ants find their way

...biguous situation was set up. Ants were trained to search for food between two cylinders of different sizes ...ow which cylinder is which? They were only able to search in the predicted place when a patterned background was introduced as a retrieval cue. Professor Coll...

Plague proteome reveals proteins linked to infection

...thors said the same approach is being applied to a search for biomarkers across a wide range of biological systems, from other infectious agents such as Salmonella to soil microbes of interest in cleaning up toxic waste. ...

Researchers discover new gene responsible for brittle bone disease

... While the study is an important early step in the search for a cure, its immediate effect may be to exonerate an expanded group of parents whose children frequently appear in emergency rooms with unexplained fractures, and who may be accused of child abuse. The study was led by Brendan Lee, M.D., Ph.D....

Tuberculosis: The bacillus takes refuge in adipose cells

...nces. This work highlights the importance of the search for new targeted therapeutic weapons, such as new antibiotics, which must be able to reach the dormant bacillus that has been hiding in adipose cells without our knowing it. ...

Honey bee genome holds clues to social behavior

...m the binding site, the gene is switched off. To search for genes that might play a role in social behavior, Sinha and his colleagues used the newly sequenced honey bee genome to scan the binding sites of transcription factors known to function in the development of fruit flies (Drosophila melanogaster) f...

Scientists' cell discovery unearths evolutionary clues

...vestigate the origin of these amoebas, and also to search for new species and to establish their position on the family tree. Meanwhile, a number of research projects, including teams in the USA and Germany, have won sponsorship to sequence the genomes of social amoeba species identified by the work in York...

Parasitic plants sniff out hosts

...row and attempt to locate its host. Dodder plants search for hosts by growing and moving in a circular pattern. In the past, many assumed that the search was random and the location of a host simply a chance encounter. After four days, when the plant wa...

Genetic 'roadmap' charts links between drugs and human disease

...t of the Human Genome Project -- to accelerate the search for new drugs to treat disease. "The Connectivity Map works much like a Google search to discover connections among drugs and diseases," said senior author Todd Golub, the director of th...

Scientists use gene signatures to match cancer and other diseases with potentially effective drugs

...he Human Connectivity Map works much like a Google search to discover connections among drugs and diseases," explained Todd Golub, MD, who is an investigator at Dana-Farber, the head of the Cancer Program of the Broad Institute, an associate professor of pediatrics at Harvard Medical School, and a Howard Hu...

Electric fish in Africa could be example of evolution in action

..., Cornell neurobiologists armed with oscilloscopes search for shapes and patterns of electricity created by fish in the water. They know from their previous research that the various groups of local electric fish have different DNA, different communication patterns and won't mate with each other. However,...

NAU researchers chirping over discovery of new cricket genus

...caves, robotic cave explorers will be developed to search for life under the Martian surface. His second project involves developing procedures for rapidly inventorying cave biodiversity. He has applied these methods to caves throughout northern Arizona and Belize. He will be applying these techniques to ca...

Producing bio-ethanol from agricultural waste a step closer

...hD degree for his research into the subject. The search for alternatives to the current, oil-based, fuels is the focus of great interest around the world. One of the most attractive alternatives is bio-ethanol - alcohol produced from agricultural crops. At present, bio-ethanol is only made from sugars der...

Pure novelty spurs the brain

... motivating bonus to explore an environment in the search for reward rather than being a reward itself." Also, Bunzeck and Düzel found that novelty enhanced learning in the subjects. "Thus, the human SN/VTA can code absolute stimulus novelty and might contribute to enhanced learning in the context of nove...

Statins stop hepatitis C virus from replicating

...ayama University in Japan, tested other statins in search of a more effective anti-HCV therapy. Using the OR6 cell culture assay system, they evaluated the anti-HCV activities of five statins: atorvastatin, fluvastatin, lovastatin, pravastatin and simvastatin. When the statins were tested alone, all except...

How bad is malaria anemia? It may depend on your genes

...ated deaths occur," says McDevitt. "That led us to search for a better way to identify those most at risk and a better way to treat the disease," he says. The study, published online April 24 in the Journal of Experimental Medicine, adds to a growing amount of evidence that an individual's unique genetic ...

New bird flu drug promises to beat the problem of resistance
