The first "big picture" study of the effects of rapidly rising temperatures in the northeast Atlantic Ocean shows that a major shift in fish stocks is already well underway. But it isn't all bad news. The research, published today (15th Sept.) in Current Biology, shows that some fishes' losses are other fishes' gain.

When Arctic ground squirrels are getting ready to hibernate they don't just get fat – they pack on muscle at a rate that would make a bodybuilder jealous. And they do it without suffering the harmful effects that high levels of testosterone and other anabolic steroids usually cause. University of Toronto Scarborough (UTSC) researchers have started to untangle how the squirrels manage it, and their results could someday have implications for human health.
Scientists have replaced all of the DNA in the arm of a yeast chromosome with computer-designed, synthetically produced DNA that is structurally distinct from its original DNA to produce a healthy yeast cell. (Yeast chromosomes are often depicted as bow tie-shaped--with each chromosome bearing two "arms" that are positioned similarly to the two sides of a bow tie.)
Their critics weren't convinced the first time, but Rice University researchers didn't give up on the "ice that burns."
A paper by a Rice team expands upon previous research to locate and quantify the amount of methane hydrates -- a potentially vast source of energy -- that may be trapped under the seabed by analyzing shallow core samples. The paper published this week by the Journal of Geophysical Research- Solid Earth should silence the skeptics, the researchers said.
Scientists have sequenced the genomes (genetic codes) of 17 strains of common lab mice--an achievement that lays the groundwork for the identification of genes responsible for important traits, including diseases that afflict both mice and humans.
Researchers at the University of Sheffield have developed polymers that fluoresce in the presence of bacteria, paving the way for the rapid detection and assessment of wound infection using ultra-violet light.
Scientists reveal in more detail than ever before how white blood cells kill diseased tissue using deadly granules, in research published today in PLoS Biology.
PISCATAWAY, NJ – People who drink heavily may increase their risk of dying in house fires that should otherwise have been escapable, a new study suggests.
The findings, reported in the September issue of the Journal of Studies on Alcohol and Drugs, highlight one of the less-recognized dangers of downing too much alcohol -- especially in combination with smoking.
Merck could not have bought a study this good about their GARDASIL® vaccine - turns out they didn't need to.
A new analysis says the number of cases and deaths from breast and cervical cancer are rising, especially in the developing world where more women are dying at younger ages, according to the Institute for Health Metrics and Evaluation (IHME) at the University of Washington.
Whether they are aware of it or not, consumers dislike being reminded of money—so much that they will rebel against authority figures, according to a new study in the Journal of Consumer Research.
People assume that consumers are influenced by celebrities and high-status individuals, but according to a new study in the Journal of Consumer Research, it may be the janitor or the security guard who makes you want to run out and purchase the latest gadget.
WINSTON-SALEM, N.C. – Sept. 13, 2011 – Researchers at Wake Forest Baptist Medical Center report that sickle cell trait is not a risk factor for the development of severe kidney disease in African-Americans. This study, published in the August online issue of Kidney International, contradicts findings from a 2010 study that first suggested that having one copy of the sickle cell gene was a kidney disease risk factor.
In certain situations, people actually salivate when they desire material things, like money and sports cars, according to a new study in the Journal of Consumer Research.
Researchers have developed a valuable mouse genetic blueprint that will accelerate future research and understanding of human genetics. The international team, led by researchers at the Wellcome Trust Sanger Institute and the University of Oxford, explains in two papers published in Nature on 14 September 2011 how they decoded and compared the genome sequence of 17 mouse strains.
A team of researchers from Singapore, Australia, Switzerland, the UK and the USA has carried out a comprehensive assessment to estimate the impact of disturbance and land conversion on biodiversity in tropical forests. In a recent study published in Nature, they found that primary forests – those least disturbed old-growth forests – sustain the highest levels of biodiversity and are vital to many tropical species.
