In Unique Stellar Laboratory, Einstein's Theory Passes Strict, New Test
Taking advantage of a unique cosmic configuration, astronomers have measured an effect predicted by Albert Einstein's theory of General Relativity in the extremely strong gravity of a pair of superdense neutron stars. Essentially, the famed physicist's 93-year-old theory passed yet another test.

Statins have unexpected effect on pool of powerful brain cells
Cholesterol-lowering drugs known as statins have a profound effect on an elite group of cells important to brain health as we age, scientists at the University of Rochester Medical Center have found. The new findings shed light on a long-debated potential role for statins in the area of dementia.

Geologists push back date basins formed, supporting frozen Earth theory
Even in geology, it's not often a date gets revised by 500 million years. But University of Florida geologists say they have found strong evidence that a half-dozen major basins in India were formed a billion or more years ago, making them at least 500 million years older than commonly thought.

Species Have Come and Gone at Different Rates than Previously Believed
Diversity among the ancestors of such marine creatures as clams, sand dollars and lobsters showed only a modest rise beginning 144 million years ago with no clear trend afterwards, according to an international team of researchers. This contradicts previous work showing dramatic increases beginning 248 million years ago and may shed light on future diversity.

Geologists study China earthquake for glimpse into future
The May 12 earthquake that rocked Sichuan Province in China was the first there in recorded history and unexpected in its magnitude. Now a team of geoscientists is looking at the potential for future earthquakes due to earthquake-induced changes in stress.

Radicals Shake Up Molecules in a Tug o' War
Until now, it was commonly thought that colliding molecules get the shakes as the result of energy transfer solely from the smashing of the molecules, but some new research adds a second means by which colliding molecules become vibrationally excited--it is being called the "Tug o' War Mechanism."

Visualizing atomic-scale acoustic wavesin nanostructures
Acoustic waves play many everyday roles - from communication between people to ultrasound imaging. Now the highest frequency acoustic waves in materials, with nearly atomic-scale wavelengths, promise to be useful probes of nanostructures such as LED lights.

Note to pediatricians: Taper meds in kids with stable asthma
A study of how pediatricians prescribe asthma medications suggests that while most would readily increase a child's medication if needed, many are reluctant to taper off drug use when less might be best.

Newborn vitamin A reduces infant mortality
A single, oral dose of vitamin A, given to infants shortly after birth in the developing world can reduce their risk of death by 15 percent, according to a study conducted by researchers at the Johns Hopkins Bloomberg School of Public Health. The study is published in the July 2008 edition of the journal Pediatrics.

Slow exercise (not fast) is better for menopausal women
It's an inevitable truth: as we get older, our muscles deteriorate and we become weaker. Not only can this be an immensely frustrating change, but it can also have many other, more serious implications.

Prevalence of religious congregations affects mortality rates
LSU associate professor of sociology Troy C. Blanchard recently found that a community's religious environment - that is, the type of religious congregations within a locale - affects mortality rates, often in a positive manner. These results were published in the June issue of Social Forces, a leading journal in the field of sociology.
