OAK RIDGE, Tenn., Feb. 2, 2010 — Neutron scattering experiments performed at the Department of Energy’s Oak Ridge National Laboratory give strong evidence that, if superconductivity is related to a material’s magnetic properties, the same mechanisms are behind both copper-based high-temperature superconductors and the newly discovered iron-based superconductors.
A new study led by Mark Zimmerman, MD, of Rhode Island Hospital indicates that a majority of non-psychiatrist physicians and a substantial minority of psychiatrists reported that they often do not use the criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) when diagnosing major depressive disorder (MDD) in patients.
A community workshop sponsored by SNM’s Clinical Trials Network (CTN) officially kicked off on Feb. 1, in Albuquerque, N.M., and presented participants with a series of educational sessions on the use of molecular imaging in clinical trials for investigational therapeutic drugs.
SNM’s Nanomedicine and Molecular Imaging Summit wrapped up today in Albuquerque, N.M., with in-depth discussion — and a high sense of energy looking ahead.
Fat tissue in women with Polycystic Ovary Syndrome produces an inadequate amount of the hormone that regulates how fats and glucose are processed, promoting increased insulin resistance and inflammation, glucose intolerance, and greater risk of diabetes and heart disease, according to a study conducted at the Center for Androgen-Related Research and Discovery at Cedars-Sinai Medical Center.
Researchers from the University of Granada (UGR) have compared the disaster caused by the Aznalcóllar spillage in the Doñana National Park in Andalusia 11 years ago with the biggest species extinction known to date. What do these two disasters have in common?
For 80 years it has been accepted that early life began in a ‘primordial soup’ of organic molecules before evolving out of the oceans millions of years later. Today the ‘soup’ theory has been over turned in a pioneering paper in BioEssays which claims it was the Earth’s chemical energy, from hydrothermal vents on the ocean floor, which kick-started early life.
Other parallel experiments on both women and men further demonstrates that a regular game of soccer affects numerous cardiovascular risk factors such as maximal oxygen uptake, heart function, elasticity of the vascular system, blood pressure, cholesterol and fat mass far more than e.g. strength training and just as much if not more than running.
Ann Arbor, Mich. — — About one-third of doctors and their patients with diabetes do not see eye to eye on the most important health conditions to manage, according to a survey by the University of Michigan Medical School.
San Diego, CA, February 2, 2010 — Reducing obesity and smoking have become national priorities in the United States. Research has shown that intensive counseling can positively impact each problem. However, because such counseling is typically not covered by medical insurance, cost can be a barrier.
Could humans one day walk on walls, like Spider-Man? A palm-sized device invented at Cornell that uses water surface tension as an adhesive bond just might make it possible.
Everyone checks themselves in the mirror now and then, but that experience can be horrifying for individuals suffering from body dysmorphic disorder, or BDD, a psychiatric condition that causes them to believe, wrongly, that they appear disfigured and ugly. These people tend to fixate on minute details — every tiny blemish looms huge — rather than viewing their face as a whole.
Viruses are insidious creatures. They differ from each other in many ways, and they can mutate — at times seemingly at will, as with HIV — to resist a host of weapons fired at them. Complicating matters further is that new viruses are constantly emerging.
A common plant virus lures aphids to infected plants by making the plants more attractive, but when the insects taste the plant, they quickly leave for tastier, healthier ones.
