Rensselaer researchers develop approach that predicts protein separation behavior

...humanities and social sciences. Institute programs serve undergraduates, graduate students, and working professionals around the world. Rensselaer faculty are known for pre-eminence in research conducted in a wide range of fields, with particular emphasis in biotechnology, nanotechnology, information techn...

Marine bacterium suspected to play role in global carbon and nitrogen cycles

...s is revealed, information about N. maritimus will serve as benchmarks for all microbiologists. Biochemical and genomic studies are already underway to learn the mechanisms by which N. maritimus uses nitrogen and how its physiology compares to other microorganisms. The National Science Foundation's (NSF)...

Hanging baskets of sex and death help fruit growers

...rom direct sunlight one application of virus could serve for an extended period and remove the need for constant reapplication In this Defra funded project the researchers have already tested the effect of a single dispenser which alone infected 5% of all the moths found over a 1 hectare site. That early...

After the yeast is gone bacteria continue to develop flavor of sparkling wine

...released by the yeast cells affect wine flavor and serve as nutrients for the growth of bacteria. Although yeasts have the dominating influence on the chemical composition of wine, some changes which influence the sensory quality and consumer acceptability of the wine could be due to growth and lysis of ba...

Weight control protein may yield antiobesity drugs

... SH2-B and signaling events regulated by SH2-B may serve as potential therapeutic targets for the treatment of obesity and type 2 diabetes. "Because SH2-B sensitizes both leptin and insulin, action drugs that mimic or enhance SH2-B action may improve insulin and leptin sensitivity and have potential value...

From a Few Wild Ancestors, a Citrus Cornucopia

...rees, as well as their seeds, budwood, and pollen, serve as valuable germplasm—plant tissue containing the essential genetic information needed to start new citrus plants. The citrus genebank -- a University of California-Riverside (UCR) resource that is used cooperatively by the ARS repository -- has bee...

Researchers Create DNA-Based Sensors for Nano-Tongues and Nano-Noses

...s colleagues believe arrays of these sensors could serve as passive detection systems in almost any location. The sensor surface is also self-regenerating, with each sensor lasting for more than 50 exposures to the targeted substances, which means they would not need to be replaced frequently. The specifi...

Virus uses tiny RNA to evade the immune system

...n antiviral mechanism, to generate small RNAs that serve their own purposes -- the latest chapter in the long cat-and-mouse game known to virologists as host-virus coevolution," the researchers conclude in their Nature article. ...

Forsyth scientists find three bacteria associated with oral cancer

...led us to hypothesize that the three species could serve as diagnostic indicators for OSCC. And, in fact, we found that elevated salivary counts of the three bacteria correctly identified 80% of individuals with oral cancer and 83% of controls." If their findings are replicated in future studies, the Fors...

Lactose intolerance linked to ancestral environment

... and why morning sickness occurs. "Both appear to serve an important function to protect the individual," Sherman said. "Spices contain antimicrobial compounds, and they may be used to destroy food-borne pathogens, especially in hot climates. Nausea and vomiting early in pregnancy also may protect women a...

Drugs from the deep blue

...eld of research that explores how natural products serve the organisms that produce or harbor them. The compounds could be chemical defenses to deter predators. For example, some fish "taste" food items before swallowing them, sometimes spitting the item out and sucking it back in several times before reje...

New discovery blurs distinction between human cells and those of bacteria

...osures known as microcompartments, which appear to serve as primitive organelles inside bacterial cells, carrying out special reactions in their interior. "Students who take a biology class learn in the first three days that cells of prokaryotes are uniform and without organization, while cells of eukaryo...

Nighttime Dying Linked To Sleep Apnea From Brain Cell Loss

Brain networks change according to cognitive task

.... This finding suggests that task specific regions serve as convergence zones that integrate information from other parts of the brain. The results also show that switching between tasks -- in this case between rhyming and spelling -- led to changes in the influence of the IFG on the task specific regions...

Corn grain mould used as pesticide

... the US safety limit for animal food ?cotton seeds serve as food e.g. for dairy cattle. Two years ago the 'good' mould was permitted in the US as an organic pesticide. Five kilos of mould-infected grains of corn are sufficient to 'inoculate' an area of one hectare ?this means that the method is relatively...

UW scientists report a new method to speed bird flu vaccine production

...kidney cell line to make non-virulent viruses that serve as the raw material for vaccines.The technique reported by the Wisconsin team improves upon a previous reverse genetics method (developed by Kawaoka's group in 1999) by significantly reducing the number of plasmid vectors required to ferry viral gene...

Drug resistant avian influenza viruses more common in Southeast Asia than North America

...g of infectious disease outbreaks globally; and to serve as a central location for news, updates, and discussions of infectious disease outbreaks that threaten humans. For example, a ProMED transmission on July 6, 2005 noted that Joseph Domenech, the chief veterinary officer for the United Nations Food and...

Research casts doubt on circulating stem cells

...Bonn medical scientists, means the cells would not serve as a substitute for defective muscle cells. The study is reported on 1st August in the online section of the science journal PNAS (www.pnas.org , PNAS Early Edition). Bone marrow constantly produces stem cells from which, among other things, the whi...
