As the national debate rages over health care reform, Lara Shore-Sheppard, associate professor of economics at Williams College, says one thing is clear: "doing nothing is definitely worse than doing something. Shore-Sheppard notes that while the debate can seem complex, the need for reform comes down to two big issues. "First, a large chunk of the American population has unstable health coverage, or no coverage whatsoever. Second, health care costs are high and rising." President Obama, she says, is tackling coverage first. Shore-Sheppard knows a little something about health coverage; she has spent much of her career studying the effect of expanding children's access to Medicaid.
It can happen in an instant: a father grabs his daughter’s arm before she runs out into traffic, and the sudden pull produces sharp pain and loss of movement in her arm.
The July eclipse will be the 49th solar eclipse that Jay Pasachoff has viewed. A champion of using eclipse observations to study the solar atmosphere, he describes the science of eclipses in the cover story of the international journal Nature (June 11 issue). Pasachoff, who is chair of the International Astronomical Union's Working Group on Solar Eclipses, was invited to write the article as part of Nature's coverage of the International Year of Astronomy.
Investigators at Burnham Institute for Medical Research have deciphered a large percentage of the total protein complement (proteome) in Schizosaccharomyces pombe (S. pombe) fission yeast.
Two new systematic reviews have found that acupuncture therapy can provide patients who suffer from tension and migraine headache an alternative treatment for their pain.
Feeling sleepy? That's because parts of your brain are actually asleep, according to a new theoretical paper by sleep scientists at Washington State University. Contrary to conventional wisdom, they say, there's no control center in your brain that dictates when it's time for you to drift off to dreamland. Instead, sleep creeps up on you as independent groups of brain cells become fatigued and switch into a sleep state even while you are still (mostly) awake. Eventually, a threshold number of groups switch and you doze off.
Two studies look at possible outcomes for older hip patients.
Study finds that older patients' concerns often go unspoken and unaddressed.
A team of researchers, led by Stony Brook University paleontologist David Krause, Ph.D., has discovered in Madagascar the remains of what may be the largest frog ever to exist. Moreover, the 16-inch, 10-pound ancient frog, scientifically named Beelzebufo, or devil frog, links a group of frogs that lived 65 to 70 million years ago to some types living today in South America.
When quizzed about their knowledge in diagnosing tuberculosis and deciding on the best treatment, medical residents in Baltimore and Philadelphia get almost half the answers wrong, according to a survey by TB disease experts at Johns Hopkins and elsewhere.

Scientists have learned that some naturally occurring atmospheric chemicals react with sunlight more effectively than previously thought to produce substances that "scrub" the air of smog.
