Magnetic resonance imaging (MRI)—a widely used medical tool that relies on magnetic fields and radio waves to visualize the body's internal structures, especially soft tissues—may soon become even more useful.

LIVERMORE, Calif. - Understanding the key elements of biofuel combustion is an important step toward insightful selection of next-generation alternative fuels.
And that's exactly what Lawrence Livermore and Sandia national laboratories researchers intend to do.
In a new paper on the cover of the May 10 edition of the journal Angewandte Chemie, Sandia researcher Nils Hansen and Lawrence Livermore scientist Charles Westbrook take a look at the vastly diverse and complex chemical reaction networks of biofuel combustion.
PASADENA, Calif.—A team of scientists from Columbia University, Arizona State University, the University of Michigan, and the California Institute of Technology (Caltech) have programmed an autonomous molecular "robot" made out of DNA to start, move, turn, and stop while following a DNA track.
Just as cooking helps people digest food, pretreating polycarbonate plastic — source of a huge environmental headache because of its bisphenol A (BPA) content — may be the key to disposing of the waste in an eco-friendly way, scientists have found. Their new study is in ACS' Biomacromolecules, a monthly journal.
LIVERMORE, Calif. — Understanding the key elements of biofuel combustion is an important step toward insightful selection of next-generation alternative fuels.
And that's exactly what researchers at Sandia and Lawrence Livermore national laboratories are doing.
The journal Angewandte Chemie devotes its May 10 cover to a paper co-authored by Sandia's Nils Hansen and Lawrence Livermore's Charles Westbrook, which examines the essential elements of biofuel combustion.
Vaccination of infants with Rotarix or RotaTeq significantly reduces the rate of severe rotavirus diarrhoea, hospitalizations, medical attention due to rotavirus and severe diarrhoea from all causes. The vaccines are not associated with increased numbers of serious adverse events. These are the conclusions of a Cochrane Systematic Review published in the May 2010 issue of The Cochrane Library.
A new type of procedure for correcting short-sightedness could be safer than laser eye surgery, according to a new Cochrane Systematic Review. The study also shows that patients prefer the new procedure, despite there being little difference between the two in terms of improving vision.
There is an urgent need for longitudinal cohorts based in sub-Saharan Africa to address the growing burden of non-communicable diseases in the region, according to a new article published in PLoS Medicine. Michelle Holmes from the Channing Laboratory at Harvard Medical School and colleagues argue that public health in sub-Saharan Africa has historically focused on communicable diseases including HIV/AIDS, malaria and other infectious disease.
AMES, Iowa – The metal poles that carry power lines across the country are built to take whatever blows at them. So they're big and round and sturdy – as much as 12 feet in diameter and 100 feet high.
WASHINGTON, May 11—Researchers from around the world will present the latest breakthroughs in electro-optics, innovative developments in laser science, and commercial applications in photonics at the 2010 Conference on Lasers and Electro-Optics/Quantum Electronics and Laser Science Conference (CLEO/QELS) May 16 to 21 at the San Jose McEnery Convention Center in San Jose, California.
Research Highlights of the Meeting:
INDIANAPOLIS – As the United States moves toward the goal of a secure nationwide health information network (NHIN), a new study from the Regenstrief Institute provides a framework for evaluating the costs, effort and value of what is sometimes referred to as the health internet.
The study, which appears in the May/June 2010 issue of Journal of the American Medical Informatics Association, also reports on the initial assessment of that framework by health information exchange experts across the nation.
The car is not the only vehicle that can be propelled electrically. Lecturers at the Higher Nautical and Naval Engineering Technical School, Mikel Lejarza, Jose Ignacio Uriarte, Miguel Ángel Gómez Solaetxe and Juan Luis Larrabe are part of a research team working on an innovative project: to have a sailing boat that can undertake port manoeuvres (such as mooring and unmooring) using electric energy obtained from the movement of the wind in their sails when sailing and thus reduce the use of fuel and the emission of waste and noise.
A joint Agricultural Research Service (ARS)-multi-university study across the central Great Plains on the effects of more than 19 years of various tillage practices shows that no-till makes soil much more stable than plowed soil.
