Anthrax paralyzes immune cells with lethal toxin, UF research shows

...essages within the cell. As a result, immune cells never receive the green light to assemble the actin motor, Southwick's findings demonstrate. "Together, these studies provide important clues about how anthrax escapes the immune system during infection," said Nick Duesbery, Ph.D. deputy director for re...

World's leading scientists announce creation of 'Encyclopedia of Life'

... making this encyclopedia real are within reach as never before." Ultimately, the Encyclopedia of Life will provide users the opportunity to personalize the learning experience through its "my eol" feature. The site can be made available in all major languages and will connect scientific communities co...

Herpes infection may be symbiotic, help beat back some bacteria

... then enter periods of latency. Sometimes symptoms never recur; sometimes they flare up periodically before becoming quiescent again. In addition, less infamous herpes viruses like HHV6 and HHV7 permanently infect most humans without ever producing any significant symptoms. The results have potentially ...

The quest for an effective HIV vaccine presents new possibilities, challenges

... stages of HIV infection, even though the virus is never completely eliminated. Vaccines that induce strong cellular immune responses may have some benefits, say the authors. In non-human primate models of HIV infection, T-cell vaccines have reportedly decreased the total amount of virus produced during ea...

Iowa State scientists demonstrate first use of nanotechnology to enter plant cells

... at the same time and at the same location. That’s never been done before." The controlled release will improve the ability to study gene function in plants. And in the future, scientists could use the new technology to deliver imaging agents or chemicals inside cell walls. This would provide plant biol...

Do fruit flies have free will?

...e University of Hamburg by surprise: "I would have never guessed that simple flies who otherwise keep bouncing off the same window have the capacity for nonrandom spontaneity if given the chance." The researchers tethered fruit flies (Drosophila melanogaster) in completely uniform white surroundings and...

Study of protein folds offers insight into metabolic evolution

...he evolution of genes and organisms but which have never before been used to work out the evolutionary history of protein architecture across biological networks. "We are interested in how structure evolves, not how organisms evolve," said professor of crop sciences Gustavo Caetano-Anollés, principal re...

Danish researches solve virus puzzle

..., trick the cell into producing something which it never would have done otherwise. Understanding the role of the pseudoknots can be an important step in developing a viral vaccine. ...

Cloning the smell of the seaside

... but the genes responsible for its production have never before been identified. The new findings will be published in the journal Science on Friday February 2. "By isolating a single gene from a bacterium collected from the mud of Stiffkey marshes, we deduced that the mechanisms involved in DMS product...

Biodiesel study targets cleaner air, cleaner engines

... Although commercially available, biodiesel has never been tested on agricultural machinery in Canada and has not yet been widely used by farmers. It is hoped the research results ?expected in early May ?will help increase demand for biodiesel, which in turn will increase market opportunities for recycl...

Transfusion expert urges wider use of filtered blood

...hat some studies included hundreds of patients who never received blood transfusions. These patients would have been irrelevant to a study assessing the risks and/or benefits of certain types of transfusions, because they couldn't have benefited nor could they have been harmed by a transfusion. Furthermore...

New report: Explosive growth changes salmon industry

...en and fishing communities. "Wild salmon could never supply the market demand being met by farmed salmon. A fundamental point of the report is that the debate should not be about wild versus farmed, but whether each method of production is being done right," says Dr. Gunnar Knapp, professor of economi...

Researchers identify ovarian cancer biomarkers

New player in commitment to life as a fat cell

...xygen species, and its involvement in gout. It has never been looked at in the context of fat development before." The findings further suggest that adipose-tissue XOR may be a contributing factor to other symptoms commonly seen in obese individuals, including high blood levels of uric acid (hyperuricem...

LIAI completes world's most comprehensive analysis on influenza virus data

...earchers ways of sharing knowledge and information never available before. Previously, everyone did their own study, but would have no way of knowing if a particular epitope had been used one time, for example by a single individual responding to a single virus, or 100 different times. Now, scientists ca...

Smithsonian scientists discover new marine species in eastern Pacific

...n 50 percent of the ribbon worms he collected have never been seen before. Norenburg studies ribbon worms ranging from those so tiny they live between grains of sand to 6-foot-long specimens that eat entire crabs and sea hares. During the expedition, Norenburg discovered new species of ribbon worm...

When your brain talks, your muscles don't always listen

"My early interests were based on sport, but my career in this field now allows me to address a much larger population that needs our knowledge," Knight said. "Exercise is still the means for improvement, and aging is a process that u...

Scientists clone mice from adult skin stem cells

...a handful may succeed ?with reported success rates never reaching into double digits. "The efficiency of nuclear transfer is very low," says Li. "Using purified adult skin stem cells as our source of nuclei, we have found that higher nuclear transfer efficiencies can be achieved." Greco, Guasch and Li...
