New protein vital for immune response is found in surprise location

...ts. Dr. Chen and his research group are currently working to determine how the MAVS protein functions within the complex series of biochemical reactions that takes place when the body is infected with a virus. Researchers at UT Southwestern, led by microbiologist Dr. Michael Gale, and elsewhere have previo...

Study shows how retinoic acid enters a cell's nucleus

...n exposed to a hormone or a drug. Noy currently is working with an ILBP that she has pinpointed as a pro-carcinogen -- it promotes cancer. Armed with new tools and knowledge, she hopes to figure out how to suppress the ability of this protein to move to the nucleus and promote cancer, perhaps by blocking the...

Scientists discover stem cell origin of neck and shoulders

...d Biological Sciences Research Council (BBSRC) and working with international collaborators, used a new genetic technique to tag embryonic stem cells and then trace them to the adult animal. They discovered that instead of homogeneous groups of stem cells making up the bones of the shoulder and neck and anot...

Divergent life history shapes gene expression in brains of salmon

Scientists working with salmon have found that gene expression in the brain can differ significantly among members of a species with different life histories. Their study indicates that roughly 15 percent of Atlantic salmon genes show differential expression in males w...

New clue to cocaine addicts' quirky behavior

Researchers working with rats have zeroed in on the brain circuitry mechanism whose disruption contributes to the impulsive behavior seen in users of cocaine as well as other psychostimulant drugs. The same circuitry has been implicated in such disorders as schizophreni...

Bacteria are key to 'green' plastics, drugs

....S. Department of Agriculture. Bennett and San are working with Manhattan, Kansas-based AgRenew Inc., which just began testing how to use farm-grown products like grain sorghum as feedstocks for the succinate-producing bacteria. "We are very pleased for the opportunity to continue our collaboration with our...

Tetanus toxin found to have therapeutic properties

...utic and cosmetic applications, the scientists are working with sublethal doses of toxins. Led by José Aguilera, scientists from the Department of Biochemistry and Molecular Biology and the Institute of Neuroscience at the UAB, have studied whether it would also be possible to use sublethal doses of tetanus...

New Scripps Oceanography project to study sediments and ecosystem restoration in Venice lagoon

... The SIOSED team will be part of a Scripps-Venice working group that will include scientists from Scripps, Thetis, the National Research Council Institute of Marine Science of Venice and the Marine Biology Laboratory of Trieste and promises to integrate Scripps' scientific expertise with knowledge of the la...

Laboratory professionals in Africa receive training under AIDS Relief Plan

...bia, Lesotho, Swaziland and Viet Nam. ASCP will be working in Ethiopia, Tanzania, South Africa, Zambia, Lesotho and Swaziland. In the past year, 14 ASCP volunteer members have played roles assessing the situation in Africa, serving as trainers, and participating in Work Groups developing training materials...

Gene Bridges And Covalys To Develop Restriction-Enzyme-Free SNAP-tag Gene Fusion Kits

...ts will be enthusiastically welcomed by scientists working with BAC resources." Prof. A. Francis Stewart, Chairman of Gene Bridges, said, "BACs are the new treasures of molecular biology. Most online genomes are annotated with readily available BACs, so that it is easy to identify and obtain a BAC encoding ...

New research could help us deliver genes for new bone formation

UK scientists are working on new methods to regenerate cartilage and bone by delivering genes to stem cells within the body to instruct them to turn into bone cells. The research, funded by the Biotechnology and Biological Sciences Research Council (BBSRC), could lead to a ne...

Investigating 'brain shrinkage' in alcoholics

...s improve with abstinence," said Harper. "Although working memory, postural stability, and visuospatial ability may continue to show impairment for weeks to months with sobriety, with prolonged sobriety these brain functions can show improvement." - Some alcoholics can achieve long-term abstinence in spite ...

Secrets to antibody's success against West Nile Virus surprise scientists

... than 90 percent. Scientists at Macrogenics are working on the preliminary studies required before the West Nile antibody can be tested in humans. Meanwhile, researchers at Washington University wanted to know why the new antibody was so effective. Antibodies normally work by binding to invaders to fla...

UNC computer, marine scientists collaborate to predict flow of toxic waters from Katrina

...DL, with assistance from Luettich and Blanton, are working to integrate information provided by the computational calculations with NOAA's North American Mesoscale Model, the primary weather forecasting model used by the National Weather Service, to simulate wind speed, direction and other weather factors. T...

A slight difference and significant similarities

...nck research group head Oliver Fiehn, who has been working at the University of California in Davis since the beginning of 2005, developed some ingenious methods to do this during his time in Potsdam. These methods, which are known in technical jargon as metabolomics and are both technically and statisticall...

Mayan stingless bee keeping: Going, going, gone?

...itat loss. "In our initial surveys of bee keepers working with native bees in the eighties, we estimated that they maintained more than a thousand active hives. In 1990, we only found around 400 hives, and in 2004, only 90. At this rate, we would expect the art of stingless bee keeping to disappear from the...

Discovery of T-cell 'traffic control' boosts new drug promise

... trapped by the drug for a few days, but still are working fine and allowing new antibody formation," he explains. Treatment using this drug strategy does not come without risks, Goetzl cautions. Current drugs that affect one type of S1P receptor affect all others as well, and some of these control heart ra...

Defect in gene causes 'neuralgic amyotrophy'

...onnected with the University of Antwerp, have been working with colleagues from the universities of Munster (Germany) and Seattle (USA). The researchers studied several large families and identified the gene responsible for the disorder. They have now shown that HNA is linked to the long arm of chromosome ...

Rensselaer researchers develop approach that predicts protein separation behavior

...grams serve undergraduates, graduate students, and working professionals around the world. Rensselaer faculty are known for pre-eminence in research conducted in a wide range of fields, with particular emphasis in biotechnology, nanotechnology, information technology, and the media arts and technology. The I...

Simple sea sponge helps scientists understand tissue rejection

...splant patients reject their new organs requires a working knowledge of how cells recognize and accept or reject each other. Xavier Fernndez-Busquets, an MBL researcher visiting from the University of Barcelona, has found the perfect ally in this quest: the red beard sea sponge, an Atlantic species that grow...
