ALBUQUERQUE, N.M. — Sandia National Laboratories researchers have taken the first steps toward reducing the size and enhancing the functionality of devices in the terahertz (THz) frequency spectrum.
By combining a detector and laser on the same chip to make a compact receiver, the researchers rendered unnecessary the precision alignment of optical components formerly needed to couple the laser to the detector.
Bethesda, Md. (June 29, 2010) – It's no secret that UVB radiation from the sun causes wrinkles. However, a Japanese study published in the American Journal of Physiology—Regulatory, Integrative and Comparative Physiology (http://ajpregu.physiology.org/)indicates that oxygen may help combat the formation of wrinkles by lessening tissue damage done by UVB rays.
Philadelphia, PA, June 29, 2010 – The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (Medicare Part D) added prescription drug coverage to Medicare beginning in January 2006. This has dramatically reshaped the prescription drug insurance market and has had significant effects on insurers, beneficiaries, and providers. For researchers, it has provided a rich source of research questions to examine.
Rome, Italy: Scientists have discovered that when they transplant ovaries from young mice into aging female mice, not only does the procedure make the mice fertile again, but also it rejuvenates their behaviour and increases their lifespan. The question now is: could ovarian transplants in women have the same effect?
OAK BROOK, Ill. – Arthroscopic surgical repair of torn anterior cruciate ligaments (ACL) or meniscal cartilage injuries in the knee does not decrease the chances of developing osteoarthritis, according to a new study published in the online edition and August print issue of the journal Radiology.
A decade after the initial injuries were diagnosed using MRI, localized knee osteoarthritis was evident in patients, regardless of whether or not the injuries had been surgically repaired.
Even at a hospital recognized for managing seriously ill patients, a systematic assessment of clinical measures associated with end-of-life care identified opportunities to improve treatment for those dying in the hospital, according to a report in the June 28 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
Patients admitted to a teaching hospital for an end-of-life illness generally receive high-quality medical care, but there is a need for better communication about family expectations and for timely efforts to keep patients comfortable, according to a new study.
The project examined the care provided to patients who died over a one-year period at Ronald Reagan UCLA Medical Center, a large teaching hospital known for providing aggressive care to patients who are critically ill.
ORLANDO, Fla., June 28 – Advances in treatment and care have reduced overall death rates from type 1 diabetes, with women and African-Americans having higher risks of mortality, according to a University of Pittsburgh Graduate School of Public Health study being presented at the 70th Scientific Sessions of the American Diabetes Association.
Cambridge, Mass., – June 28, 2010 – "More than meets the eye" may soon become more than just a tagline for a line of popular robotic toys.
Researchers at Harvard and MIT have reshaped the landscape of programmable matter by devising self-folding sheets that rely on the ancient art of origami.
Health conscious consumers have long known that virgin olive oil is a good choice when it comes to preparing meals and dipping breads. Now, a team of researchers, including one with the Agricultural Research Service (ARS), has found that phenolic components in olive oil actually modify genes that are involved in the inflammatory response.
Americans are almost universally aware of the oil spill in the Gulf of Mexico, and they are concerned about its potential impact on the safety of Gulf seafood, according to new data from a continuing survey conducted by the University of Minnesota.
The survey is part of an ongoing weekly consumer confidence poll conducted by The Food Industry Center at the U of M. During the most recent survey, 99 percent of respondents said they were aware of the spill and 85 percent say they are following news about it closely or have heard a lot about it.
VERNON - No significant differences in corn yield were found between organic and chemical sources of nutrients, but a Texas AgriLife Research economist said manure generates higher economic returns than anhydrous ammonia.
Dr. Seong Park, AgriLife Research economist, recently had his research published in the Agronomy Journal. The work was from studies he conducted in the Oklahoma Panhandle while at Oklahoma State University and finalized while in his new position at Vernon.
ANN ARBOR, Mich.---University of Michigan aquatic ecologist Donald Scavia and his colleagues say this year's Gulf of Mexico "dead zone" is expected to be larger than average, continuing a decades-long trend that threatens the health of a $659 million fishery.
