Stroke survivors who smoke put themselves at a greater risk of additional strokes, heart attack or death than those who never smoked, according to new research in the American Heart Association's journal Stroke. Those who quit smoking before their stroke also had less risk of poorer outcomes than current smokers, researchers found. Researchers in Melbourne, Australia, tracked 1,589 patients who experienced a first or recurrent stroke in 1996-99. They followed them for 10 years, using medical records and in-person and telephone interviews, and tracked demographics, ...

In a new study out today, researchers used mice to identify a combination six naturally occurring bacteria that eradicate a highly contagious form of Clostridium difficile, an infectious bacterium associated with many hospital deaths. Three of the six bacteria have not been described before. This work may have significant implications for future control and treatment approaches. The researchers found that this strain of C. difficile, known as O27, establishes a persistent, prolonged contagious period, known as supershedding that is very difficult to treat with antibiotics. ...

When the era of regenerative medicine dawned more than three decades ago, the potential to replenish populations of cells destroyed by disease was seen by many as the next medical revolution. However, what followed turned out not to be a sprint to the clinic, but rather a long tedious slog carried out in labs across the globe required to master the complexity of stem cells and then pair their capabilities and attributes with specific diseases. In a review article appearing today in the journal Science, University of Rochester Medical Center scientists Steve Goldman, ...

STONY BROOK, NY– In a Perspectives article, "The Risks of Overfishing," published today in the journal Science, Dr. Ellen K. Pikitch, executive director of the Institute for Ocean Conservation Science and professor at Stony Brook University, cautions against continuing traditional fisheries management. According to Dr. Pikitch, current and recent studies demonstrate the need for "a more precautionary approach to fisheries management, in which fishing is restricted to those places and amounts where it can be conducted safely and with minimal risk of jeopardizing the integrity ...

Children's parties or activity days, where prospective adopters meet children awaiting adoption, could be part of the solution to the current adoption crisis, according to research that will be showcased during the Economic and Social Research Council (ESRC) Festival of Social Science. "Such parties or activity days went out of fashion in the 1980s but no one is sure why," says Katherine Runswick-Cole of Manchester Metropolitan University who led the research. "However, our pilot study has shown an overwhelmingly positive response from practitioners, adopters and the ...

This press release is available in German. Pulsars are the compact remnants from explosions of massive stars. Some of them spin around their own axis hundreds of times per second, emitting beams of radiation into space. Until now, they could only be found through their pulsed radio emissions. Now, scientists at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute/AEI) in Hanover assisted by the Max Planck Institute for Radio Astronomy have discovered a millisecond pulsar solely via its pulsed gamma radiation. A new data analysis method developed ...

Smoking reduces life expectancy by ten years in Japan, but much of the risk can be avoided by giving up smoking, a paper published on bmj.com today shows. Previous studies in Japan suggested smoking reduced life expectancy by only a few years compared with about ten years in Britain and the USA. This new report, from researchers in Oxford and Japan, investigates the impact of smoking on mortality in a large group of Japanese people who were living in Hiroshima or Nagasaki in 1950. The findings are, however, nothing to do with radiation exposure from the bombs. The ...

This represents the first drop in overall spending since Research!America began compiling the data in 2002. The decline follows an uptick in research funding attributed to the American Recovery and Reinvestment Act (ARRA), which allocated $10.4 billion to the National Institutes of Health (NIH) over two fiscal years (2009-2010). ...

In a tropical cyclone, strong uplift of air pushes the tops of thunderstorms high into the troposphere. When that strength wanes, the cloud tops drop and become less cold. That's because the higher you go in the troposphere, the colder it gets. NASA satellite infrared data has revealed that Tropical Storm Tony's cloud top temperatures are warming and the storm is weakening. The Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite captured infrared imagery of Tropical Storm Tony on Oct. 24 at 12:17 p.m. EDT that showed the strongest thunderstorms ...

JOHANNESBURG, SOUTH AFRICA (October 25, 2012) – A recent report says illegal hunting of wildlife in South African Development Community (SADC) states can lead to the eradication of many species across extensive areas and even complete ecological collapse. Africa's iconic large carnivores, such as cheetah, lion, leopard, and wild dog, are particularly vulnerable to this practice, either because they are caught in the bycatch from unselective methods such as snaring, or due to loss of prey. The report says that the scale and severity of the threat is such that, without ...

(SACRAMENTO, Calif.) -- A team of UC Davis scientists has shown in experimental mouse models that a new drug delivery system allows for administration of three times the maximum tolerated dose of a standard drug therapy for advanced bladder cancer, leading to more effective cancer control without increasing toxicity. The delivery system consists of specially designed nanoparticles that home in on tumor cells while carrying the anti-cancer drug paclitaxel. The same delivery system also was successfully used to carry a dye that lights up on imaging studies, making it potentially ...

LA JOLLA, CA – October 25, 2012 – Explosive advancement in human genome sequencing opens new possibilities for identifying the genetic roots of certain diseases and finding cures. However, so many variations among individual genomes exist that identifying mutations responsible for a specific disease has in many cases proven an insurmountable challenge. But now a new study by scientists at The Scripps Research Institute (TSRI), Scripps Health, and Scripps Translational Science Institute (STSI) reveals that by comparing the genomes of diseased patients with the genomes of ...

CHESTNUT HILL, MA (October 25, 2012) – In the relatively new scientific frontier of topological insulators, theoretical and experimental physicists have been studying the surfaces of these unique materials for insights into the behavior of electrons that display some very un-electron-like properties. In topological insulators, electrons can behave more like photons, or particles of light. The hitch is that unlike photons, electrons have a mass that normally plays a defining role in their behavior. In the world of quantum physics, where everyday materials take on surprising ...

In the future, warmer waters could significantly change ocean distribution of populations of phytoplankton, tiny organisms that could have a major effect on climate change. Reporting in this week's online journal Science Express, researchers show that by the end of the 21st century, warmer oceans will cause populations of these marine microorganisms to thrive near the poles and shrink in equatorial waters. "In the tropical oceans, we are predicting a 40 percent drop in potential diversity, the number of strains of phytoplankton," says Mridul Thomas, a biologist at Michigan ...

EAST LANSING, Mich. — Warmer oceans in the future could significantly alter populations of phytoplankton, tiny organisms that could have a major impact on climate change. In the current issue of Science Express, Michigan State University researchers show that by the end of the 21st century, warmer oceans will cause populations of these marine microorganisms to thrive near the poles and may shrink in equatorial waters. Since phytoplankton play a key role in the food chain and the world's cycles of carbon, nitrogen, phosphorous and other elements, a drastic drop could have ...
