New technique helps identify multiple DNA regulatory sites

...), single strands of DNA essentially self-assemble upon a surface to duplicate a nano-scale pattern made of their complementary DNA strands. The duplicates are identical to the master and can thus be used as masters themselves. This increases print output exponentially while enabling the reproduction of v...

Team of international scientists departs today to discover the unknown in China's Himalayan region

... "Expedition Everest: Mission Himalayas" builds upon a long-time relationship between CI and Disney to support biodiversity conservation. Since 1995, Disney Wildlife Conservation Fund (DWCF) and the Walt Disney Company Foundation have contributed to several CI initiatives including a Global Amphibian A...

Rodent social behavior encoded in junk DNA

... "An animal's response to vasopressin thus depends upon which rooms have the locks and our research shows that the distribution of the receptors is determined by the length of the microsatellites." Prairie voles with the long version have more receptors in circuits for social recognition, so release of v...

Nanowires can detect molecular signs of cancer, scientists find

...ancer markers in healthcare will ultimately depend upon the development of techniques that allow rapid detection of many markers with high selectivity and sensitivity. "Genomics and proteomics research has elucidated many new biomarkers that have the potential to greatly improve disease diagnosis," the s...

Neurologix announces positive results of gene therapy clinical trial in Parkinson's disease

...taining 3.5, 10 or 35 billion particles (depending upon dose cohort) of the AAV (adeno-associated virus) viral vector with a human GAD gene (cDNA) were then infused at 0.5 microliters/minute, together with 15 microliters of 25% mannitol. After the 100-minute infusion period, the delivery catheter was wi...

Seaweed could make junk food healthier

Scientists at the University of Newcastle upon Tyne publish their findings in the academic journal Critical Reviews in Food Science and Nutrition, in a paper detailing alginate's many benefits to the body. They believe it will be a valuable weapon in the international battle against obesity, dia...

Hybrid grass may prove to be valuable fuel source

...im to measure the rate of photosynthesis depending upon ambient sunlight. Preliminary results show that Miscanthus has a 27 percent greater rate of photosynthesis at midday compared with switchgrass. Nine different fields across the state are being used to help estimate Miscanthus productivity, Heaton sa...

Stem Cells Found In Cerebellum; Possible Cell of Origin for Childhood Brain Tumors

... what they believed to be contaminating cells. But upon closer examination, these turned out to include a small population of neural stem cells, said Audra Lee, a research associate in Wechsler-Reya's lab who carried out the majority of the work. The stem cells they isolated represented less than one per...

A new molecule discovered in the battle between plants and disease

...s, evidenced by a more robust leaf and root growth upon infection. ProAtPep1 belongs to a seven member gene family in Arabidopsis with tissue-specific paralogs that exhibit differential expression profiles. Orthologs of the proAtPep1 gene have been identified in important crop species including canola, so...

Novel mechanism for DNA replication discovered

...replicating strand. The cytosine is inserted based upon the coding information in Rev1 regardless of whether a guanine or another base is present on the DNA. "This is the first time we have seen a protein serving as a template for DNA synthesis," said Dr. Aggarwal. "This provides an entirely new mechanis...

Redesigned protein accelerates blood clotting

...ease factor VIII potency. "Our goal is to improve upon nature by developing gain-of-function factor VIII proteins that are superior to the factor VIII protein found in healthy individuals," Fay said. "These more potent forms are not likely to occur naturally since they would theoretically result in exces...

Doctors should stop prescribing antibiotics for the common cold, review advises

...es. Colds are caused by viruses and not bacteria, upon which antibiotics act, yet, says Arroll, "There is evidence of high usage of antibiotics for the common cold in spite of doubts about the efficacy of such therapy." The review appears in the current issue of The Cochrane Library, a publication of The...

Size matters: Preventing large mammal extinction

...ied animals require a different approach, focusing upon the specific species, their biology and their habitat. "This understanding enables us to predict what species are most at risk in the future," said Dr Purvis. "That provides a way for conservationists to go on the front foot rather than wait for acc...

Scientists at Galileo Pharmaceuticals confirm inflammatory response linked to glucose levels

...ic basis of the disease and these can now be built upon for the development of treatments. "There is no doubt that we need new approaches," said Kosik. "The insights gained about the mechanisms of the molecular and genetic basis of the disease are beginning to add up and can be harnessed for treatments." ...

Bumblebees copy one another when contending with unfamiliar flowers

...er species that they had tried before, they relied upon their own individual initiative. It's not yet possible to say why bumblebees visit flowers that other bees are foraging on, but it could be that bees learn that the presence of another bee provides an efficient shortcut to success. These findings pr...

Unusual antibiotics show promise against deadly 'superbugs'

Proteomics brings researchers closer to understanding microbes that produce acid mine drainage

...xtracellular polymers that make the biofilm matrix upon which all community members depend," Banfield said. "It's like it's a slave." The team also was able to identify important acid-stable proteins, including the iron oxidizing protein in Leptospirillum group II bacterium, that may have technological a...
