It is suitable as a kind of magnetic valve for data-storage units of the most recent generation and makes use of effects in the context of so-called spintronics, with which, in addition to the (re-)charging process, magnetic characteristics of the electrons can also be used for information-processing and -storage. The advantage of the new structure: data remain intact even after the electric current has been switched off and the memory can be re-written more or less indefinitely.
A complex and fascinating portrait of a society suffering the effects of the deepest recession since the early 1990s and in which young people appear to have been hardest hit is revealed by new findings from the UK's largest longitudinal household survey Understanding Society. The research published also shows that efforts to get more students from poorer backgrounds to go to university have not been successful and that more needs to be done to get teenagers to live a healthier life in order to assure their future happiness.
PHILADELPHIA – Only about 75 percent of HIV/AIDS patients in the United States remain in care consistently, according to new research from the Perelman School of Medicine at the University of Pennsylvania published online this week in AIDS. The study of patients across the United States is the first to provide a comprehensive national estimate of HIV care retention and information about patients who are most likely to continue their treatment over time.
Bethesda, MD—A new research discovery by a team of Stanford and European scientists offers hope that people with atherosclerotic disease may one day be able to avoid limb amputation related to ischemia. A new research report appearing online in the FASEB Journal suggests that the delivery of genes for two molecules naturally produced by the body, called "PDGF-BB" and "VEGF" may successfully cause the body to grow new blood vessels that can save ischemic limbs.
SEATTLE – March 5, 2012 – Remove your shoes at the door of your home to avoid tracking in pollutants. Decrease consumption of processed and canned foods. Avoid the use of plastics with recycling codes #3, #4 and #7. Don't use chemical tick and flea collars or dips for pets.

Elderly people with the metabolic syndrome—defined as having multiple risk factors associated with developing diabetes and heart disease—had an increased risk of chronic kidney disease, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).
The majority of institutionalized elderly female patients are vitamin D deficient and there is an inverse association of vitamin D deficiency and mortality, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology and Metabolism (JCEM).
PITTSBURGH, March 5 – Family members of patients in the intensive care unit (ICU) tend to be overly optimistic about the possibility of recovery despite being told that the prognosis is grim, according to a study led by researchers at the University of Pittsburgh School of Medicine.

SEATTLE – A small, early-phase clinical trial to test the effectiveness of treating patients with advanced melanoma using billions of clones of their own tumor-fighting cells combined with a specific type of chemotherapy has shown that the approach has promise. One patient of the 11 experienced a long-term, complete remission that has lasted more than three years, and in four others with progressive disease, the melanoma temporarily stopped growing.
Santa Barbara, CA – The ocean is becoming an increasingly crowded place. New users, such as the wind industry, compete with existing users and interests for space and resources. With the federal mandate for comprehensive ocean planning made explicit in the National Ocean Policy, the need for the transparent evaluation of potential tradeoffs is now greater than ever.
Newcastle University scientists, in work funded by Arthritis Research UK, have discovered a new way of potentially treating rheumatoid arthritis. This works by preventing damaging white blood cells cells from entering the joints.
Using a unique drug, they are able to stop destructive white blood cells migrating from the bloodstream into inflamed tissue and so preventing them causing further injury.
COLUMBUS, Ohio – Just a few minutes of listening to mainstream rock music was enough to influence white college students to favor a student group catering mostly to whites over groups serving other ethnic and racial groups, a new study found.
However, white students who listened to more ethnically diverse Top 40 pop music showed equal support for groups focused on whites, African Americans, Arab Americans and Latino Americans.
