ANAHEIM, March 27 2011 — Scientists are spending scarce government money to study mysterious black stripes in the rainbow of light given off by celestial objects millions of light-years across the universe. There is no practical use for knowledge about these colors missing from the glow of Andromeda, Triangulum and other distant galaxies. Nevertheless, their research on this arcane topic, termed Diffuse Interstellar Bands (DIBs), gives birth to a new, multibillion-dollar-per-year industry on Earth.

ANAHEIM, March 27, 2011 — Scientists are reporting on a new material containing an ingredient used to make bricks that shows promise as a transparent coating for improving the strength and performance of plastic food packaging. Called "nano-bricks," the film even looks like bricks and mortar under a microscope, they say. The coating could help foods and beverages stay fresh and flavorful longer and may replace some foil packaging currently in use, they note.
ANAHEIM, March 27, 2011 — A curtain of flame halts firefighters trying to rescue a family inside a burning home. One with a special backpack steps to the front, points a wand at the flame, and shoots a beam of electricity that opens a path through the flame for the others to pass and lead the family to safety.
ANAHEIM, March 27, 2011 — Scientists today claimed one of the milestones in the drive for sustainable energy — development of the first practical artificial leaf. Speaking here at the 241st National Meeting of the American Chemical Society, they described an advanced solar cell the size of a poker card that mimics the process, called photosynthesis, that green plants use to convert sunlight and water into energy.
ANAHEIM, March 27, 2011 — Scientists today reported the first strong evidence implicating nicotine as the main culprit responsible for persistently elevated blood sugar levels — and the resulting increased risk of serious health complications — in people who have diabetes and smoke. In a presentation at the 241st National Meeting & Exposition of the American Chemical Society (ACS), they said the discovery also may have implications for people with diabetes who are using nicotine-replacement therapy for extended periods in an attempt to stop smoking.
How does your best friend feel when people act needy? Or, about people being dishonest? What do they think when others seem uncomfortable in social situations? According to an upcoming study in Psychological Science, a journal of the Association for Psychological Science, if you don't know – your relationship may pay a price.
Studies done by Mark Lusk and colleagues at the Colorado School of Mines could significantly improve the efficiency of solar cells. Their latest work describes how the size of light-absorbing particles--quantum dots--affects the particles' ability to transfer energy to electrons to generate electricity.
The results are published in the April issue of the journal ACS Nano.
A two-year energy audit of Hamilton schools has identified energy conservation measures that could reduce their energy costs by almost $2.4 million annually. The audit was conducted by engineering faculty and students at McMaster University
The measures, presented today to officials from the Hamilton-Wentworth District School Board and the Hamilton-Wentworth Catholic District School Board, range from recaulking windows, adding insulation and using more efficient lighting to new investments in advanced heat recovery systems and boilers, and solar and wind generating systems.
The largest-ever assessment of high-deductible health plans finds that while such plans significantly cut health spending, they also prompt patients to cut back on preventive health care, according to a new RAND Corporation study. The findings are published in the March edition of the American Journal of Managed Care.
Washington, D.C. – A national survey of U.S. family medicine residency programs finds that most limit pharmaceutical and other industry interactions with residents while many exclude all interactions. The results, published in the May issue of Academic Medicine, suggest a major shift away from acceptance of food, gifts, samples, and industry-supported events. The survey was a joint effort between Georgetown University Medical Center and the American Medical Student Association (AMSA).
Menlo Park, Calif. — Scientists have found the strongest evidence yet that a puzzling gap in the electronic structures of some high-temperature superconductors could indicate a new phase of matter. Understanding this "pseudogap" has been a 20-year quest for researchers who are trying to control and improve these breakthrough materials, with the ultimate goal of finding superconductors that operate at room temperature.
Two satellites designed and constructed by students at the Cockrell School of Engineering successfully separated in space March 22, completing the most crucial goal of the mission since its Nov. 19 launch and making them the first student-developed mission in the world in which satellites orbit and communicate with each other in real-time.
Arlington, Va. (March 24, 2011) – Researchers with the Los Angeles County Department of Public Health have found high rates of the multi-drug resistant pathogen, carbapenem-resistant Klebsiella pneumoniae (CRKP) among the patient population in long-term acute care hospitals compared to general acute care hospitals across the county. These findings are particularly important because CRKP was thought to be contained to East Coast facilities and communities.
A number of American men who have sex with men are supportive of couples-based voluntary HIV counseling and testing (CVCT), in which couples receive counseling and their HIV test results together, according to a new study by Dr. Rob Stephenson from Rollins School of Public Health in Atlanta, USA, and his colleagues. The authors argue that there may be a demand among gay men for this effective strategy, used in Africa amongst heterosexual couples, albeit with some adaptations to the protocol to make it relevant in the US.
The multitouch microscope integrates two Finnish innovations and brings new dimensions into teaching and research.
Researchers at the Institute for Molecular Medicine Finland (FIMM) have in collaboration with the Finnish company Multitouch Ltd created a hand and finger gesture controlled microscope. The method is a combination of two technologies: web-based virtual microscopy and a giant-size multitouch display.
