Researchers find new way to attack inflammation in Graves' eye disease A small group of patients with severe Graves' eye disease experienced rapid improvement of their symptoms -- and improved vision -- following treatment with the drug rituximab. Inflammation around their eyes and damage to the optic nerve were significantly reduced. The same patients had not previously responded to steroids, a common treatment for Graves' eye disease.

Possible help in fight against muscle-wasting disease A compound already used to treat pneumonia could become a new therapy for an inherited muscular wasting disease. A five-member team of researchers from University of Oregon and the University of Rochester School of Medicine and Dentistry report that pentamidine might be adapted to counter genetic splicing defects in RNA that lead to type 1 myotonic dystrophy.

Computer predicts reactions between molecules and surfaces, with ‘chemical precision’ An international team of scientists from the Netherlands, Spain, Norway, Argentina and the United States has shown in a paper to be published in Science shortly how the chemistry of surface reactions underpinning catalysis can be modeled accurately with computers.

Past climate of the northern Antarctic Peninsular informs global warming debate The seriousness of current global warming is underlined by a reconstruction of climate at Maxwell Bay in the South Shetland Islands of the Antarctic Peninsula over approximately the last 14,000 years, which appears to show that the current warming and widespread loss of glacial ice are unprecedented.

'Dropouts' pinpoint earliest galaxies Astronomers, conducting the broadest survey to date of galaxies from about 800 million years after the Big Bang, have found 22 early galaxies and confirmed the age of one by its characteristic hydrogen signature at 787 million years post Big Bang. The finding is the first age-confirmation of a so-called dropout galaxy at that distant time and pinpoints when an era called the reionization epoch likely began.

New synthetic molecules trigger immune response to HIV and prostate cancer Researchers at Yale University have developed synthetic molecules capable of enhancing the body's immune response to HIV and HIV-infected cells, as well as to prostate cancer cells. Their findings, published online in the Journal of the American Chemical Society, could lead to novel therapeutic approaches for these diseases.

Chemists describe solar energy progress and challenges, including the 'artificial leaf' Scientists are making progress toward development of an "artificial leaf" that mimics a real leaf's chemical magic with photosynthesis -- but instead converts sunlight and water into a liquid fuel such as methanol for cars and trucks. That is among the conclusions in a newly available report from top authorities on solar energy who met at the 1st Annual Chemical Sciences and Society Symposium. The symposium was organized by the American Chemical Society and other scientific societies. Contact: Michael Bernstein Public Release: 5-Nov-2009

November 2009 story tips from the US Department of Energy's Oak Ridge National Laboratory Fuel economy ratings for the new 2010 model year automobiles are posted at www.fueleconomy.gov, which ORNL maintains for the US Department of Energy and the US Environmental Protection Agency. A team led by ORNL's Nina Balke has moved closer to developing more rugged memory and logic devices. Heavy trucks are less heavy but just as safe and rugged because of steel rail frames. A new approach to crunching massive volumes of data uses neural networks like an artificial brain. Contact: Ron Walli Public Release: 5-Nov-2009
Are the Alps growing or shrinking? The Alps are growing just as quickly in height, as they are shrinking. This paradoxical result could be proven by a group of German and Swiss geoscientists. Contact: F. Ossing Public Release: 5-Nov-2009
Researchers explore new ways to prevent spinal cord damage using a vitamin B3 precursor Substances naturally produced by the human body may one day help prevent paralysis following a spinal cord injury, according to researchers at Weill Cornell Medical College. A recent $2.5 million grant from the New York State Spinal Cord Injury Research Board will fund their research investigating this possibility. Contact: Andrew Klein Public Release: 5-Nov-2009
Does prostate-specific antigen velocity help in early detection prostate cancer? The November issue of European Urology, the official journal of the European Association of Urology, features an article focusing on prostate specific antigen velocity and early cancer detection. It has been suggested that changes in PSA over time aid prostate cancer detection. Contact: Lindy Brouwer Public Release: 5-Nov-2009
PTB Terahertz calibration satisfies US laser manufacturer Terahertz radiation still lies in a metrological no man's land -- a metrology gap. The Physikalisch-Technische Bundesanstalt can now close this gap. For the first time, a commercial Terahertz laser was traced back to the international system of units by measuring its output power absolutely. Therefore, this laser is the first THz laser in the field with a reliably proven output power enabled by a novel calibration capability set up at the PTB.

Boat tail reduces truck fuel consumption by 7.5 percent A boat tail, a tapering protrusion mounted on the rear of a truck, leads to fuel savings of 7.5 percent. This is due to dramatically improved aerodynamics, as shown by road tests conducted by the Dutch PART (Platform for Aerodynamic Road Transport) public-private partnership platform.

Jülich neutron scientists inaugurate unique device in the US A unique large-scale research device from Jülich went into operation in the US yesterday. At the strongest neutron source in the world, the spallation source SNS in Oak Ridge, Tenn., Forschungszentrum Jülich inaugurated a so-called neutron spin echo spectrometer. The NSE spectrometer enables detailed observations to be made of the motion of proteins and polymers. It will thus help to develop improved plastics or to understand metabolic processes in cells.

German high-school students involved in an astronomical research project Astronomy & Astrophysics publishes the results of an unusual research project, by a team involving German high-school students. They present an accurate, long-term ephemeris of the cataclysmic variable EK Ursae Majoris, obtained using a professional remotely-controlled telescope.

New type of supernova explosion reported; predicted by theoretical physicists at UCSB A new class of supernova was discovered by scientists at Berkeley and may be the first example of a new type of exploding star. A team of astrophysicists at UC Santa Barbara had predicted this kind of explosion in their theoretical work. Contact: Gail Gallessich Public Release: 5-Nov-2009
Rapid supernova could be new class of exploding star UC Berkeley post-doc Dovi Poznanski was looking through seven-year-old data when he chanced upon a very strange supernova that flashed and was gone in less than a month, when 3-4 months is typical. The unusually rapid supernova appears to match the predicted behavior of a thermonuclear explosion on a white dwarf that is drawing helium from its binary companion. This mechanism is quite different from the two standard types of supernovae. Contact: Robert Sanders Public Release: 5-Nov-2009

Genomes of biofuel yeasts reveal clues that could boost fuel ethanol production worldwide As global temperatures and energy costs continue to soar, renewable sources of energy will be key to a sustainable future. An attractive replacement for gasoline is biofuel, and in two studies published online in Genome Research, scientists have analyzed the genome structures of bioethanol-producing microorganisms, uncovering genetic clues that will be critical in developing new technologies needed to implement production on a global scale.

How size matters for catalysts University of Utah chemists demonstrated the first conclusive link between the size of catalyst particles on a solid surface, their electronic properties and their ability to speed chemical reactions. The study is a step toward the goal of designing cheaper, more efficient catalysts to increase energy production, reduce Earth-warming gases and manufacture a wide variety of goods from medicines to gasoline.

Does green tea prevent cancer? Evidence continues to brew, but questions remain Although scientists are reluctant to officially endorse green tea as a cancer prevention method, evidence continues to grow about its protective effects, including results of a new study published in Cancer Prevention Research, a journal of the American Association for Cancer Research, which suggests some reduction in oral cancer.
