Intelligently designed molecular evolution

...nzyme synthase, it naturally makes a soup of small amounts of 52 different products. We were able to focus it instead on making large amounts of one of seven of those products." While the researchers have not yet reached the point where they...

Vaccine provides 100 percent protection against avian flu virus in animal study

...ng said. But now with the ability to sequence vast amounts of DNA in shorter time periods, the science is pressing forward. DeLong and his colleagues saw a unique opportunity for a "proof-of-principle" study by combining new microbial genomic profiles with decades of data collected at Station ALOHA, a Natio...

Sweetgum tree could help lessen shortage of bird flu drug

...he seeds of the sweetgum fruit contain significant amounts of shikimic acid, the starting material used to produce the main antiviral agent in a much-heralded drug for fighting bird flu. Their findings, which could help increase the global supply of the drug, were described today at the 231st national meetin...

Liquid ventilation

...rtificial surfactant, but not always in sufficient amounts to provide correct therapy. In order to alleviate this situation, the Nautical School at the University of the Basque Country has developed a liquid respiration respirator. The machine simulates placentary respiration by filling the lungs of the pre...

Powerful new tool for studying brain development

...nologies to gather, organize, format and use large amounts of biological information. "Our ability to link images of gene expression patterns to information on those genes in other databases increases the value of each new gene discovery," Mehta said. This integration of multiple research approaches and inf...

York researchers develop pollution-busting plants to clean up contaminated land

... from the bacteria and put it in plants with large amounts of biomass. A tree, for instance, is effectively a big pump, seeking out water, and if we can redeploy the enzyme which degrades the explosive making it harmless, it combines the capabilities of soil bacteria with the high biomass and uptake properti...

Mining for gems in the fungal genome

..., Bok designed a fungal strain that produced extra amounts of LaeA. This time, the team searched for groups of over-active genes, which they knew were likely secondary metabolite gene clusters. The team's new approach located 40 active gene clusters; previously, fewer than ten secondary metabolites were ...

Detection of DNA on nanotubes offers new sensing, sequencing technologies

...A could be placed in living cells and detect trace amounts of harmful contaminants. In a paper accepted for publication in the journal Nano Letters, and posted on its Web site, the researchers report they have taken the technique a significant step further. "We have successfully demonstrated the optical det...

Tastier tomatoes in the future?

...nd wild tomatoes. "On one hand, we measured higher amounts of essential amino acids and vitamins, on the other hand the fruits showed an altered combination of various sugars and organic acids," Fernie says. These contents have a great influence on the taste of tomatoes. The scientists used molecular biolog...

Evidence for omega 3 fats less conclusive than we thought, say experts

...e general public to eat more oily fish, and higher amounts are advised after a heart attack. Researchers analysed 89 studies (48 randomised controlled trials and 41 cohort studies) to assess the health effects of long and short chain omega 3 fats on total mortality, cardiovascular events, cancer, and stroke...

There's something fishy about human brain evolution

...ey brain nutrient. Iodine is present in much lower amounts from terrestrial food sources such as mammals and plants. It was this combination of abundant shoreline food and the "brain selective nutrients" that sparked the growth of the human brain, he says. "Initially there wasn't selection for a larger b...

However, previous studies carried out by Norman Hollenberg's research team at Harvard Medical School have found that Kuna who have migrated to the suburbs of Panama City on the mainland consume on...

Researchers release new variety of asparagus

In the case of DePaoli, first a male parent and a female parent are selected for their good characteristics including spear size, spear qua...

Protecting endangered species helps reduce poverty

Applying knowledge of species movements in and across habitats can help implement such sustainable land-use planning. For example, in Tortuguero, Costa Rica, live turtles are worth more to the local economy than turtle mea...

Defective immune system response to smallpox vaccine detailed in new study

Adding IL-4 and IL-13 to skin cells from healthy volunteers prior to vaccinia exposure reduced levels of LL-37 production. Conversely, when the scientists applied IL-4- and IL-13-neutralizing antibodies to skin samples from people...
