Leesburg, VA, May 5, 2014—Misinformation and misunderstanding about the risks associated with ionizing radiation create heightened public concern and fear, and may result in avoidance of screening mammography that can detect early cancers.

Leesburg, VA, May 5, 2014—Breast tomosynthesis in the diagnostic workup for one- or two-view focal asymmetry detected at screening mammography resulted in less use of ultrasound, fewer biopsies, and higher positive predictive value for cancer than when diagnostic exams involved only 2D mammography, according to a study conducted at the University of Virginia.
"Tomosynthesis has been evaluated in screening populations and been shown to decrease recall rates," said researcher Brandi Nicholson, "but studies in the diagnostic setting are lacking."
Surprisingly, researchers found that visiting a specialist prior to melanoma diagnosis may reduce their risk of dying by 90 percent.
STANFORD, Calif. — New research could soon make it easier for people with type-1 diabetes to get a safe night's sleep, says a Stanford University School of Medicine scientist who led the study.
In a large trial conducted in patients' homes in the United States and Canada, scientists demonstrated that they could predict and prevent dangerously low overnight blood sugars in adolescents and adults with type-1 diabetes.
HUNTSVILLE, TX (5/7/14) -- Gang members are twice as likely to become both a victim and an offender of a crime than non-gang members, as single acts of violence often lead to retribution between gangs as a whole, according to a new study.
While flexible gadgets such as "electronic skin" and roll-up touch screens are moving ever closer to reality, their would-be power sources are either too wimpy or too stiff. But that's changing fast. Scientists have developed a new device that's far thinner than paper, can flex and bend, and store enough energy to provide critical back-up power for portable electronics. Their report appears in the Journal of the American Chemical Society.
Orlando, Fla. — Researchers have found that, contrary to prvious clinical trial findings, monthly injections to counteract age-related macular degeneration (AMD) may not be necessary. The research is being presented at the 2014 Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO) this week in Orlando, Fla.
PULLMAN, Wash. - Drug abuse, acts of rampage – what's really the matter with kids today? While there are many places to lay blame – family, attitude, peers, school, community – a new study shows that those risks vary in intensity from kid to kid and can be identified.
ROCHESTER, Minn. — New research from Mayo Clinic shows that implementing a uniform method to care for lower-risk cardiac surgical patients improves outcomes, reduces patients' time in the hospital and lowers overall per patient costs by 15 percent. The study is published in the May issue of Health Affairs.

Unlike medical records kept in paper charts, electronic health records (EHR) provide numerous access points to clinicians to review a patient's medical history.
In 2012, John B. Gurdon and Shinya Yamakana were awarded the Nobel Prize in medicine for discovering that adult cells can be reprogrammed into pluripotent ones (iPS); the cells obtained are capable of behaving in a similar way to embryonic stem cells, and hence have enormous potential for regenerative medicine.
However, although there are many research groups around the world studying this process, it is still not completely understood, it is not totally efficient, and it is not safe enough to be used as the basis for a new cell therapy.
WASHINGTON D.C. May 6, 2013 -- The eye is an exquisitely sensitive system with many aspects that remain somewhat of a mystery—both in the laboratory and in the clinic.
A U.S.-based team of mathematicians and optometrists is working to change this by gaining a better understanding of the inner workings of tear film distribution over the eye's surface. This, in turn, may lead to better treatments or a cure for the tear film disease known as "dry eye." They describe their work in the journal Physics of Fluids.
The sight of seabirds following trawlers in order to feast from discarded fish is a common maritime sight, but each year many thousands of seabirds are killed by overhanging cables or in nets. New research in Animal Conservation assesses mortality figures from South Africa to show that a simple bird scaring line can reduce the mortality rate by over 90%.
Although the nation is spending more on welfare than ever before, most of that money is going to better-off families rather than the very poorest, a researcher found.
ANN ARBOR—Forget the "me" generation. A new analysis of long-term trends in egotism shows there's been a "me" century in America.
The analysis, conducted by researchers at the University of Michigan, shows that characteristics related to self-interest, compared to interest in the lives and needs of other people, was low during the 19th century but rose steadily after the turn of the 20th century.
