Darwin's famous finches and Venter's marine microbes

...lifornia. The company specializes in hardware that accelerates genomic searches. "We only have one of their accelerators, but Time Logic stepped up and lent us eight more," says Manning. The final computation took two weeks, but would have taken well over a century on a traditional computer. The Salk scienti...

Antibody signal may redirect inflammation to fuel cancer

... arthritis. "We already know that inflammation accelerates skin, cervical and colon cancer, and most likely also lung and breast cancer," she said. "If we confirm that what we've discovered in the mice studies also occurs in human cancers, we may soon be in a good position to slow this cancer process using d...

NIH neuroscience microarray consortium launches high-throughput genotyping services

... a nation-wide technology outlet that dramatically accelerates the pace of neuroscience research," said Consortium Chairman Dr. Dietrich Stephan, who is also the director of TGen's Neurogenomics Division. "Implementing these high throughput genotyping services will ultimately make a dramatic impact in clinical c...

Down syndrome: It's not just the age factor

...and it might explain why the rate of Down Syndrome accelerates with increasing maternal age. These findings have important implications for the prevention of abnormal fetal development. The authors conclude that "clearly, identification of the relaxation control mechanisms and therapeutic restoration of a st...

Wheat gene may boost foods' nutrient content

...ed GPC-B1 for its effect on Grain Protein Content, accelerates grain maturity and increases grain protein and micronutrient content by 10 to 15 percent in the wheat varieties studied so far. To prove that all these effects were produced by this gene, the researchers created genetically modified wheat lines with ...

Diabetes research takes wing thanks to long-lived fruit fly

...ore aggressively against the oxidative stress that accelerates with aging. Such stress comes from the same chemical process that makes cars rust in the Rochester winter: Free-wheeling molecules known as free radicals zing through materials and run roughshod over anything in their way, including vital proteins an...

Prion find points way to test for human 'mad cow' disease

...on (PMCA), invented by Soto's group, which greatly accelerates the process by which prions convert normal proteins to misshapen infectious forms. "With this method, for the first time we have detected prions in what we call the silent phase of infection, which in humans can last up to 40 years," said Soto, seni...

Carnegie Mellon researchers discover new cell properties

...dren suffering from an extremely rare disease that accelerates the aging process by about seven times the normal rate. Dahl, an assistant professor of chemical and biomedical engineering at Carnegie Mellon, said her work with researchers at the National Cancer Institute of the National Institutes of Health (NIH...

New MRI technique shows emphysema in asymptomatic smokers

...an in active smokers. "On average, active smoking accelerates emphysema-like changes at about twice the normal rate found with aging," Dr. Fain explained. In addition to early disease detection, hyperpolarized MRI can also be used to plan surgical therapies and to monitor patient response to drug therapies wit...

Hopkins researchers discover genetic switch that turns off an oxygen-poor cell's combustion engine

... It was already known that during hypoxia, HIF-1 accelerates the output of ATP by glycolysis, Dang noted. But until now researchers thought that HIF-1 simply turned up glycolysis and let the mitochondrion slow down on its own and produce less ATP, he said. Because the mitochondrion runs on oxygen, it doesn't w...

MBL leads effort to update E. coli genome

...mation resource. "Interaction among the scientists accelerates discovery and the hope is that this kind of work will soon be centralized," she said. "This would provide more efficient coordination of scientific groups that are working independently." ...

First demonstration of 'teaching' in non-human animals

...if the gap between them gets too small, the leader accelerates and the follower decelerates. It is as if the leader is towing the follower but the process is highly intermittent because the follower is dictating the speed of the lesson by stopping frequently to consolidate its growing knowledge of the path that...

Polymer aids in blood clotting, pointing way to new treatment

...dicine at Urbana-Champaign. The inorganic compound accelerates two parts of the coagulation cascade -- the contact-activation pathway and factor V, a protein that forms thrombin -- leading to fibrin and clots. Finally, he said, polyphosphate delays the breakdown of clots, which causes renewed bleeding. "The net...

Scientists design potent anthrax toxin inhibitor

...ide from its inherent toxicity, anthrax toxin also accelerates the disease process. Thus, combining antibiotics with a toxin inhibitor might act synergistically to lessen or halt anthrax symptoms, notes Dr. Kane. Using the same technique of placing multiple peptides on a liposome, the researchers also created a...

Texas scientists discover how a hepatitis C protein promotes liver cancer

...blastoma protein, a critical tumor suppressor, and accelerates its breakdown," Lemon said. He continued: "The way NS5B docks with the retinoblastoma protein is biochemically almost identical to the way a protein made by human papilloma virus does so to produce similar cancer-promoting results. That's interesting...

Tadpole soon to help in the fight against cancer and lymphedema

...ork can be studied with the help of tadpoles. This accelerates research of the lymphatic vessel network. With tadpoles one can now very quickly identify new genes that play a part in the development and functioning of the lymphatic vessel network. This is a first step in the search for solutions for illnesses re...

Gene loss accelerates aging

...have discovered that the loss of a gene called p63 accelerates aging in mice. Similar versions of the gene are present in many organisms, including humans. Therefore, the p63 gene is likely to play a fundamental biological role in aging-related processes. "To study how the p63 gene works, we devised a system fo...

Deficient DNA Repair Capacity Associated With Increased Risk Of Breast Cancer

... contributes to the accumulation of DNA damage and accelerates the genetic changes involved in carcinogenesis. To evaluate whether reduced DNA repair capacity in the nucleotide excision pathway that fixes DNA alterations known as bulky DNA adducts is associated with breast cancer risk, Regina M. Santella, Ph.D....
