Molecular physics: There's one rule for the rich...
The rich are getting richer while the poor remain poor. If you doubt it, ponder these numbers from the US, a country widely considered meritocratic, where talent and hard work are thought to be enough to propel anyone through the ranks of the rich. In 1979, the top 1 per cent of the US population earned, on average, 33.1 times as much as the lowest 20 per cent. In 2000, this multiplier had grown to 88.5. If inequality is growing in the US, what does this mean for other countries?  more

The formation of a blood clot, known as a thrombus, in a deep leg vein can be a very serious condition that often causes permanent damage to the leg veins and vein valves, known as post-thrombotic syndrome. Early treatment with blood thinners in the emergency room is important to prevent a life-threatening pulmonary embolism, but blood thinners do not treat and dissolve the existing clot, which remains in the leg.  more


New AHRQ-funded study on computerized order entry finds flaws that could lead to errors, points to opportunities for improvement

Biochemists report discovery of structure of major piece of telomerase; implications for cancer
UCLA biochemists have determined the three-dimensional structure of a major domain of telomerase, the enzyme that helps maintain telomeres small pieces of DNA on the ends of chromosomes that act as protective caps -- allowing DNA ends to be copied completely when cells are replicated.  more

Growing your own replacement teeth? Not science fiction!
Dental medicine is on the brink of profound change due, in large measure, to unprecedented advances in science and technology.

Study shows depressed heart disease patients fail to take prescribed life-saving medication
Depression is known to be "hard on the heart" now researchers are a step closer to understanding why. A new Columbia University Medical Center study examining potential links between depression and heart disease found that heart disease patients who showed symptoms of depression were substantially less adherent to taking a prescribed medicine than patients without depression. Patients who continued to show signs of depression three months after a heart attack or angina only took prescribed medications 67 percent of the time, compared to almost 90 percent in non-depressed patients.  more
