Mayo researchers discover HIV dependence on a human protein

... safer methods of gene therapy. The details appear today in the journal Science. "How an incoming virus co-opts the cell's assistance as it proceeds to establish its permanently integrated state is a fascinating question," says Eric Poeschla, M.D., the Mayo Clinic virologist who led the research. "It's cr...

Protein splicing upsets the DNA colinearity paradigm

...universal genetic code. However, a paper published today in Science by a team from the Brussels Branch of the global Ludwig Institute for Cancer Research (LICR) and the Seattle-based Fred Hutchinson Cancer Research Center (FHCRC), shows that a protein can be rearranged so that it is no longer colinear with...

Finding an answer to Darwin's Dilemma

...assive "snowball" glaciers. New findings reported today shed light on why, after three billion years of mostly single-celled evolution, these large animals suddenly appeared in the fossil record. In a paper published on-line in Science Express, Dr. Narbonne’s team argues that a huge increase in oxygen...

Siberian lakes burp 'time-bomb' greenhouse gas

...e warming, said Katey Walter, in a paper published today in the journal Nature. Walter's project is the first time this type of bubbling has been accurately quantified. "We realized that our previous estimates were missing a very large and important component of lake emissions - in these bubbles were the ...

End of deforestation in view? Experts advance new way to size up global forest resources

... plantations will grow from an estimated one-third today to half by 2025 and three-quarters by 2050. "Plantations and the trade to make them effective reduce the impact of industrial pressures on the expanse of natural forests, which may be rich in soil carbon and biodiversity," adds Dr. Sedjo. Im...

Using nature's most primitive anti-viral defense system to find new approaches to cancer research

...iruses. This system, called RNAi, is still present today in humans, plants and animals. Recently, we have learnt how to harness this anti-viral system, so that we can use it to silence the function of any normal or mutant gene at will. This new technology has the potential to change forever the way researc...

Engineer ramps up protein production, develops versatile viral spheres

...s than current methods, Swartz says. Most vaccines today work by introducing dead or weakened copies of viruses, mixed with other chemicals, into the bloodstream with the hope that they will provoke a strong, albeit general, response by the immune system. The process is akin to advertising a product to a r...

Edge density key to controlling gypsy moth spread
