Detection of DNA on nanotubes offers new sensing, sequencing technologies

...y reported that DNA-wrapped carbon nanotubes could serve as sensors in living cells now say the tiny tubes can be used to target specific DNA sequences. Potential applications for the new sensors range from rapid detection of hazardous biological agents to simpler and more efficient forensic identification...

Fruit fly's beating heart helps identify human heart disease genes

...earch team has found that the common fruit fly can serve as a powerful new model for testing human genes implicated in heart disease. The finding is important, the Duke team said, because the entire genome of the fruit fly is well understood and catalogued, enabling researchers to systemically screen gene...

UCLA scientists find male gene in brain area targeted by Parkinson's

...hts into who is at risk for the disease. "SRY may serve as a protective agent against Parkinson's," he said. "Men who contract the disease may have lower levels of the gene in the brain." Because SRY is found only in males, Vilain thinks women must possess another physiological mechanism that protects do...

Boosting newborns' immune responses

...ncovered in newborns' immune response patterns may serve an evolutionary purpose. Nature may suppress babies' production of inflammatory cytokines like TNF-alpha and IL-12 before birth because they can trigger preterm labor, while increasing production of adenosine and IL-6, which may have a protective eff...

Marine mammals are on the frontline of failing ocean health

..., and in turn our own well-being." "Wildlife can serve as a source of infection, as we have seen with the avian bird flu, but they can also be sentinels of pathogen pollution. They are often the first victims of these diseases," says Pat Conrad from the University of California at Davis. "By paying atte...

Chemotherapy gel may fight breast cancer and reduce breast deformity

...polymer-based therapy for breast cancer that could serve as an artificial tissue filler after surgery and a clinically effective therapy. Their findings, based on studies with mice, will be presented at 10:15 a.m., Tuesday, April 25 at the World Congress on Tissue Engineering and Regenerative Medicine, Apr...

High-tech tags on marine animals yield valuable data for biologists and oceanographers

...e enlisting seals, sea lions, tunas, and sharks to serve as ocean sensors, outfitting these top predators with electronic tags that gather detailed reports on oceanographic conditions and, in many cases, transmit the data via satellite. The data are proving useful to both biologists and oceanographers, yie...

Cell barrier shows why bird flu not so easily spread among humans

Researchers use dirt to stay one step ahead of antibiotic resistance

..., studying enzymes that inactivate antibiotics can serve as a foundation for the development of new combination therapies for resistant bacterial strains. Studying antibiotic resistance from an evolutionary perspective is one way that researchers are attempting to stay one step ahead of resistant bacteria...

New hybrid virus provides targeted molecular imaging of cancer

...of the hybrid virus, called AAV phage or AAVP, can serve as a vehicle for targeted delivery of genes to experimental tumors in mice and to the tumors' blood vessel supply, providing a strategy for finding tumors and genetically marking them for imaging on a clinic-ready body scanner. The AAVP hybrid combi...

Researchers solve mystery of how nuclear pores duplicate before cell division

...to the nuclear membrane and whether existing pores serve as templates had been unknown," says D'Angelo. To study this process, the Salk researchers created a cell-free system based on frog's eggs (oocytes) that was able to recapitulate the insertion of the nuclear pore complex into the nuclear membrane. U...

HortResearch science reveals the natural potential of apples

"We will see a multiplier effect, where discoveries made in other countries will benefit our work and speed up cultivar development. There will also be opportunities for HortResearch to become involved in collabora...

Earth Rx: A microbial biotechnology prescription for global environmental health

Leading the marriage are revolutionary changes in compiling vast amounts of genetic information on microbial organisms through state-of-the-art DNA-based techniques. Identifying just a sin...

Minor mutations in avian flu virus increase chances of human infection

...iet04 HA towards specific human glycans that could serve as receptors on lung epithelial cells," Wilson said. "The effect of these mutations on the Viet04 HA increases the likelihood of binding to and infection of susceptible epithelial cells." The study was careful to note that these results reveal only...

Gene-specific Ebola therapies protect non-human primates from lethal disease

...ike Ebola in nonhuman primates. The findings could serve as the basis for a new approach to quickly develop virus-specific therapies for known, emerging, and genetically engineered pathogens.
