Researchers are continuing to sound the alarm on the growing threat of multi-drug resistant gonorrhea in the United States, according to a perspective in the Feb. 9 issue of the New England Journal of Medicine. (more…)
EAST LANSING, Mich. — Many people are willing to pay a premium for ethanol, but not enough to justify the government mandate for the corn-based fuel, a Michigan State University economist argues.
Soren Anderson studied the demand for ethanol, or E85, in the United States. He found that when ethanol prices rose 10 cents per gallon, demand for ethanol fell only 12 percent to 16 percent on average. (more…)
An experimental device for removing blood clots in stroke patients dramatically outperformed the standard mechanical treatment, according to research presented by UCLA Stroke Center director Dr. Jeffrey L. Saver at the American Stroke Association’s 2012 international conference in New Orleans on Feb. 3.
The SOLITAIRE Flow Restoration Device is among an entirely new generation of devices designed to remove blood clots from blocked brain arteries in patients experiencing stroke. It has a self-expanding, stent-like design and, once inserted into a clot using a thin catheter tube, it compresses and traps the clot. The clot is then removed by withdrawing the device, thus reopening the blocked blood vessel. (more…)
The 168 rectangular panels on the roof of the Katherine Moran Coleman Aquatic Center will generate enough power to keep the lights on and enough thermal energy to heat the million-gallon pool. The center, due to open April 13, will be Rhode Island’s first hybrid (heat and power) solar installation — also the largest in the nation and the first on a college campus.
Brown is diving into solar energy. (more…)
*Geologists learn how earthquakes change the landscape — down to a few inches*
Geologists have a new tool to study how earthquakes change the landscape–down to a few inches. It’s giving scientists insights into how earthquake faults behave.
In this week’s issue of the journal Science, a team of scientists from the United States, Mexico and China reports the most comprehensive before-and-after picture yet of an earthquake zone, using data from the magnitude 7.2 event that struck near Mexicali, Mexico, in April 2010. (more…)
*Microsoft’s U.S.-based employees helped raise over US$100 million for thousands of nonprofits during the 2011 Microsoft Giving Campaign, the largest total in company history.*
REDMOND, Wash. – Microsoft employees raised a record-breaking US$100.5 million in 2011, topping last year’s total with donations to more than 18,000 community organizations across the United States and around the world.
Giving was up across the board in 2011—more employees participated, donating more time and money than ever before, which surprised some after 2010’s record year. (more…)
*In “The Great Dying” 250 million years ago, the end came slowly*
The deadliest mass extinction of all took a long time to kill 90 percent of Earth’s marine life–and it killed in stages–according to a newly published report.
It shows that mass extinctions need not be sudden events.
Thomas Algeo, a geologist at the University of Cincinnati, and 13 colleagues have produced a high-resolution look at the geology of a Permian-Triassic boundary section on Ellesmere Island in the Canadian Arctic. (more…)
HOMESTEAD, Fla. — Precipitous declines in formerly common mammals in Everglades National Park have been linked to the presence of invasive Burmese pythons, according to a study published on Jan. 30, 2012, in the Proceedings of the National Academy of Sciences.
The study, the first to document the ecological impacts of this invasive species, strongly supports that animal communities in this 1.5-million-acre park have been markedly altered by the introduction of pythons within 11 years of their establishment as an invasive species. Mid-sized mammals are the most dramatically affected. (more…)
