UF research: methyl bromide more effective, economical for killing anthrax
...anthrax," Scheffrahn said. "Chlorine dioxide is an unstable gas and may not reach the desired target sites in buildings." Chlorine dioxide is the only structural fumigant that has been approved by EPA for anthrax decontamination, but agency officials will consider crisis exemptions for other chemicals such ...New research could spearhead permanent nuclear waste storage
... radioactive, the aluminum itself is not. It is an unstable metal and so changes forms relatively easily. When an aluminum compound precipitates and becomes a solid, it can take the radioactive material with it....New NIST procedure seeks improved diagnosis of Fragile X syndrome
... especially in the range of 60 to 200, indicate an unstable "premutation" repeat length. As the number of repeats increases in successive generations, the production of a certain protein is shut off and symptoms of the disease appear or become more severe. Thus, accurate measurement of the size of the affecte...Compound identified in grapes may fight cancer and diabetes
...d in wine, Rimando says. This may be because it is unstable in light and air, which makes it less likely to survive the wine-making process, she says. The researcher is currently investigating other fruits and fruit juices to determine whether they contain pterostilbene, but results are not yet available. Th......ction. An alternative view focuses on evolution in unstable Earth environments, offering a strong basis for understanding the tendency of humans to express novelty, alter surroundings, transcend immediate space conditions, and sense the divine as part of life. Standard versions of human evolutionary history f...Genetic testing, computer risk-assessment software prove effective in predicting breast cancer
... have DNA damage. "We know that the genome becomes unstable before the cancer forms," Euhus said. "For whatever reason, certain cells in an organ stop making accurate copies of their DNA when they divide, and they don't fix DNA damage like they should." The second study compared the effectiveness of experienc...New drug that enhances glutamate transmission in the brain being evaluated for fragile X

"Once you have a patient with fragile X syndrome, that's a big red flag because that means the mutation has been in the family in a sile...Jackson researchers identify a gene implicated in oxidative stress and neurodegeneration
... metabolic functions produce free radicals--highly unstable forms of oxygen. Despite their notoriety, these molecules in fact have several beneficial roles, such as helping white blood cells attack bacteria, viruses and virus-damaged cells. Oxidative stress occurs when the amount of free radicals exceeds the ...DNA unzipping found to take at least two proteins, not one alone
...ry. It takes at least two proteins, working in an unstable tandem, to unzip two strands of DNA. Their newly designed approach, which focuses on the activity of single molecules, also showed -- for the first time -- that if one protein falls away, the process stops. Unless another climbs aboard, DNA reverts ...Bloodworm's way with copper likely provides paradigm for new materials

Normally beta-glucosidase resides and functions in macrophage lysosomes--the sac-like organelles that recycle macromolecules inside cells--where it breaks down fatty su...Scientists discover ancient protein and DNA sequences in the same fossil
...ein was recovered intact, including the relatively unstable carboxylated glutamic acid (gamma-carboxy glutamic acid) residues. As a consequence of this study, the team has a new optimism regarding the potential for protein sequencing and extending molecular records farther back in time.

...uch as gold, glass and glassy carbon proved either unstable or difficult to integrate with silicon. The biologically modified diamond films, doped with specific DNA, will be able to sense such things as anthrax, ricin, bubonic plague, smallpox and other molecules. Researchers predict that the diamond films w...Free-radical model too radical
...e compounds which generate oxygen radicals are too unstable to use in a laboratory. "You look at them wrong and they will blow up in your hand," says Tanko. So, years ago, chemists started using a specific oxygen-centered radical-- t-butoxyl radical which is easily produced from a stable and safe source, as ...West Nile Virus cases analyzed for prevalence and symptoms

The findings are important, researchers say, because some anti-cancer drug...
