Antibacterial coatings cut infection rates

...proportions. It's the furanones that come to the rescue by irreversibly switching off the bacterial signalling mechanism. Without the signal, the bacteria think that they are alone; they don't start producing the biofilm and eventually die on the surface. "We attach the furanones by covalent bonding to o...

Cord blood cells may widen treatment window for stroke

...ing normally. "These findings show we are able to rescue neurons at a time when most research suggests they are already dead." Dr. Willing presented the preliminary findings Nov. 12 at the Society for Neuroscience annual meeting in Washington, DC. The only drug currently approved for ischemic stroke trea...

Chernobyl: The true scale of the accident

...from the disaster, almost all being highly exposed rescue workers, many who died within months of the accident but others who died as late as 2004. The new numbers are presented in a landmark digest report, "Chernobyl's Legacy: Health, Environmental and Socio-Economic Impacts," just released by the Chernob...

New tooth enamel dating technique could help identify disaster victims

...nology also is being deployed to assist search and rescue crews in locating hurricane victims. This same technology was deployed in the days following the September 11 attacks in New York's World Trade Center rubble. Carbon-14, or radiocarbon, is naturally produced by cosmic ray interactions with air and i...

Sensor web simulation investigates technique to improve prediction of pollution across the globe

...ther to form and then implement a plan to find and rescue a person in need of help. Computer forecast models can also help decide where the sensors should make observations. If a model forecasts high concentrations of CO, the sensor web's instruments can be commanded to make targeted observations of those ...

Across the United States, independent pet rescue organizations are growing in number, working to pl...on to analyzing 180 homeless dog postings on a pet rescue Web site, Garcia conducted interviews with traditional animal shelter staff as well as pet rescue vo...

Research suggests fitness of Florida panthers improved by limited breeding with Texas animals

Elevated temperature enhances success of viral cancer therapy

...refore, induction of the heat shock response could rescue ONYX-015 replication in resistant tumor cells. According to Dr. O'Shea, "Our data suggest that a clinical strategy that does not advocate the use of pharmacological agents to suppress fever would favor the tumor-selective replication of ONYX-015. Th...

Wild grasses and man-made wheats advance research capabilities

... from a wild species to a hexaploid wheat and then rescue and nurture the developing embryo to get a plant, he said. Hexaploid wheat has three genomes or sets of chromosomes. This is the makeup of the typical bread wheat. After such a cross, the initial plant will have genetic abnormalities. A series of cr...

Young Blood Revives Aging Muscles, Stanford Researchers Find

...tissue. These normally lie dormant but come to the rescue in response to damaged muscle-at least they do in young mice and humans. In older mice the satellite cells hold the same position, but are deaf to the muscle's cry for help. In the Nature study, Rando and his group first attached old mice to their y...

Cellular Defects in Premature Aging Disease are Reversible

...Misteli pointed out. "So demonstrating that we can rescue the normal phenotype without cell division means this procedure could be effective in all tissues." Misteli and his group will also look more closely at healthy cells to determine how similar progeria is to the normal aging process. For more informa...
