A study by Paul Pharoah and colleagues published in this week's PLoS Medicine evaluates immunohistochemistry-based subtype classification of breast tumors for the prediction of disease outcome. Their analysis is based on more than 10,000 breast cancer cases with early disease, and examines the influence of a patient's tumour type on the prediction of future survival.

Graphane is the material of choice for physicists on the cutting edge of materials science, and Rice University researchers are right there with the pack – and perhaps a little ahead.
Researchers mentored by Boris Yakobson, a Rice professor of mechanical engineering and materials science and of chemistry, have discovered the strategic extraction of hydrogen atoms from a two-dimensional sheet of graphane naturally opens up spaces of pure graphene that look – and act – like quantum dots.
University of Alaska Fairbanks scientist Michael Whalen is part of a team of distinguished scientists who recently compiled a wide swath of evidence striking a definitive blow in the ongoing battle over what killed the dinosaurs. In a review published in the March 5 issue of the journal Science, the research group reaffirmed the recently challenged theory that an asteroid ended the age of the dinosaurs. Scientists first proposed the asteroid impact theory of dinosaur mass extinction 30 years ago.
The eruption of the volcano in Iceland has drawn attention to air flow patterns, as airlines lost millions of dollars and travelers remained stranded for days to weeks, as particles from the natural disaster traveled over Europe, forcing closures of major airports.
RIVERSIDE, Calif. – Why is there matter in the universe and not antimatter, its opposite?
CORVALLIS, Ore. – The major earthquakes that devastated Chile earlier this year and which triggered the catastrophic Indonesian tsunami of 2004 are more than just a distinct possibility to strike the Pacific Northwest coast of the United States, scientists say.
There is more than a one-in-three chance that it will happen within the next 50 years.
MADISON, WI, May 24, 2010-Scientists are exploring ways to reduce non-point pollution from agriculture. A new study finds that using straw residue in conjunction with legume cover crops reduces leaching of nitrogen into waterways, but may lower economic return.
MADISON – The "mineral-breathing" bacteria found in many oxygen-free environments may be "carbon-breathing" as well.
Oxygen-free, or anaerobic, environments contain microbes sometimes described as "mineral-breathing" because they use iron oxides and other minerals in the same way we use oxygen. According to a study published online May 23 in Nature Geoscience, this bacterial respiration may be accelerated by solid organic compounds in the soil.
EAST LANSING, Mich. --- Genetic discoveries from a shrub called the burning bush, known for its brilliant red fall foliage, could fire new advances in biofuels and low-calorie food oils, according to Michigan State University scientists.
NASA's Aqua satellite saw some strong thunderstorms in Tropical Storm 02A using infrared imagery, as it heads into the Gulf of Aden between Somalia and Yemen.
AUSTIN, Texas—A century after Albert Einstein said we would never be able to observe the instantaneous velocity of tiny particles as they randomly shake and shimmy, so called Brownian motion, physicist Mark Raizen and his group have done so.
The Northern Indian Ocean cyclone season is off to a roaring start, as the second tropical storm formed within a day of the first one. NASA's Aqua satellite flew over Tropical Storm 02A today, May 19 and captured infrared, microwave and visible images of the storm.
A study published today in the journal Nature casts doubt on the widely held notion that warming global temperatures will lead to a future intensification of malaria and an expansion of its global range.
The research, conducted by the Malaria Atlas Project (MAP), a multinational team of researchers funded mainly by the Wellcome Trust, suggests that current interventions could have a far more dramatic – and positive – effect on reducing the spread of malaria than any negative effects caused by climate change.
KNOXVILLE -- Do you know what is in your drinking water? A study by a University of Tennessee, Knoxville, professor may have you thinking twice the next time you fill up that glass of tap water.
