Computers to be used to find blueprint for new influenza drug

...any, will have been used in Britain. It will allow accurate modelling of the behaviour of tens of thousands of atoms, many times more sophisticated than previous work. “Developing a blueprint for a new way of fighting influenza is a very important task," said Professor Williams. “We often think of flu as ju...

Color-blind method opens new doors in DNA sequencing

...new way of doing DNA sequencing that could be more accurate than current methods. DNA in the nucleus of every human cell is made of long chains of building blocks called nucleotides. DNA is made up of just four types of nucleotides ?referred to as A, C, G and T ?and is organized in such a way that A binds T ...

New Clues Add 40,000 Years to Age of Human Species

...ty years ago, radiometric dating methods were less accurate and suggested an age of roughly 130,000 years. No one was able to securely tie both sets of fossils to the same time period. "Fortunately, small pumice fragments from two sediment layers were perfect for precise isotopic dating," says McDougall. ...

MSI releases 'moleculizer' - a new approach to simulation of intracellular biochemical networks

... a critical step forward in our quest toprovide an accurate simulation of intracellular biochemical networks.""I've designed Moleculizer to be intuitive for biologists," said Dr.Larry Lok, a mathematician who conceived and programmed Moleculizer."Its parallel simplifications in simulation setup and output pro...

Pathogen-Mimicking Vaccine As Strategy For Cancer Therapy

...logical monitoring across the CVC, allowing a more accurate comparison of the effects of CpG 7909 in this trial with the results of several other adjuvants that have been tested in other trials. By comparing single variables in parallel we believe we can develop effective cancer vaccines in a much shorter tim...

Molecular Motors Cooperate In Moving Cellular Cargo, Study Shows

Researchers using an extremely fast and accurate imaging technique have shed light on the tiny movements of molecular motors that shuttle material within living cells. The motors cooperate in a delicate choreography of steps, rather than engaging in the brute-force tug of war many scientists had im...

Navigating an integrated yeast network

...ps can also reveal cryptic interactions and enable accurate predictions about interactions that haven't been observed experimentally. A living cell contains thousands of proteins, genes and macromolecules, enmeshed in complex webs of relationships involving direct or indirect contact. At the simplest level, ...

New Estimates For The Causes Of Child Deaths Worldwide

The most accurate estimates of the causes of child deaths to date, published in the March 26, 2005 of THE LANCET, reveal that worldwide more than 70% of the 10.6 million child deaths that occur annually are attributable to six causes: pneumonia (19%), diarrhoea (18%),...

Study reveals new technique for fingerprinting environmental samples

...equence fingerprints can be used to provide highly accurate assessments of the vitality of extremely diverse environments," said Dr. Raymond L. Orbach, Director of the DOE Office of Science, which supported the research. "These fingerprints can be used to reveal environments under stress as well as signal pro...

First technology to remove prions that cause vCJD from blood launched

...asymptomatic for about 10 to 16 years, there is no accurate way to determine how many people could currently be harboring the disease or the magnitude of future cases. Variant CJD is transmitted by eating contaminated beef and may also be transmitted by a contaminated blood transfusion. Dr. Adrianno Aguzzi o...

Researchers discover underwater volcano

...f an underwater volcano that has emerged within an accurate period of time is very rare--this is one of those cases," said Staudigel. Scientists were tipped off to the volcano's existence when they profiled the seafloor of the Vailulu'u crater using multibeam mapping. Existing maps of the seafloor in the are...

Advancements In Genomics Foster Deep Sea Discoveries

Measuring Enzymes At End Of Cancer Pathway Predicts Outcome Of Tarceva, Taxol

...K2 is suppressed, the drug works, so developing an accurate test for CDK2 activity would be a boon for delivering individualized therapy to patients," he says. Such a test, however, will require that patients be given the drug for a short period of time so that the agent's effect on CDK2 activity can be asses...

Scripps scientists find potential for catastrophic shifts in Pacific ecosystems
