*Few parallels for today’s rapid ocean changes in geologic record*
The oceans may be acidifying faster today than they did in the last 300 million years, according to scientists publishing a paper this week in the journal Science.
“What we’re doing today really stands out in the geologic record,” says lead author Bärbel Hönisch, a paleoceanographer at Columbia University’s Lamont-Doherty Earth Observatory. (more…)
*Microsoft BizSpark One startup solves enterprise-class storage challenges with hybrid cloud approach.*
REDMOND, Wash. — March 2, 2012 — StorSimple takes an innovative approach to storage design, betting early on the Windows Azure platform and assembling a first-rate team to make cloud-integrated storage a reality for enterprise companies.
Like many other innovations, StorSimple’s breakthrough began with a fundamental observation followed by a simple question. (more…)
Asteroid 2011 AG5 has been receiving a lot of attention lately because of a very unlikely scenario which would place it on an Earth-interception course 28 years from now. Here is a scientific reality check of this relatively nondescript space rock which is currently ranked a “1” on the 1 to 10 Torino Impact Hazard Scale
As of Feb. 26, 2012, asteroid 2011 AG5 is one of 8,744 near-Earth objects that have been discovered. It is approximately 460 feet (140 meters) in size and its orbit carries it as far out as beyond Mars’ orbit and as close to the sun as halfway between Earth and Venus. It was discovered on Jan. 8, 2011, by astronomers using a 60-inch Cassegrain reflector telescope located at the summit of Mount Lemmon in the Catalina Mountains north of Tucson, Arizona. (more…)
Yale researchers have discovered how megakaryocytes — giant blood cells that produce wound-healing platelets — manage to grow 10 to 15 times larger than other blood cells.
The findings, to be published March 13 in the journal Developmental Cell, also hint at how a malfunction in this process may cause a form of leukemia. (more…)
ANN ARBOR, Mich.— Imagine two tango dancers sweeping across the dance floor and suddenly encountering a slick spot. To avoid a slip or even a nasty tumble, the pair must work together to support one another and glide safely through the stressful moment.
In a similar way, a certain type of helper protein called a stress-specific molecular chaperone prevents its client proteins from collapsing during stressful situations by uncoiling a long, supportive arm that wraps around them, a University of Michigan-led research team has shown. (more…)
UCLA stem-cell researchers have identified a certain type of cell and a signaling pathway in the placental niche that play a key role in stopping blood stem cells from differentiating into mature blood cells in the placenta. Preventing this premature differentiation is critical to ensuring a proper blood supply for an individual’s lifetime. (more…)
COLLEGE PARK, Maryland – The Israeli public is wary of launching airstrikes aimed at disrupting Iran’s ability to develop nuclear weapons, reports a new public opinion poll by researchers at the University of Maryland.
Only 19 of percent of all Israelis favored a go-it-alone strike by Israel, while 42 percent supported a strike only with U.S. backing, and 34 percent opposed any strike. Survey findings for Israeli Jews closely paralleled the results for the entire population of the nation. (more…)
In Guardians of Finance, economists Ross Levine, James R. Barth, and Gerard Caprio Jr. argue that the financial meltdown of 2007 to 2009 was no accident — it was negligent homicide. Levine speaks with Deb Baum about how that happened, what can be done, and why the home team always seems to win.
A new book co-authored by Brown University economist Ross Levine argues that the reason the United States suffers financial crises time and time again is because the major regulatory agencies — the so-called “guardians of finance” — do not work for the public. Instead, they frequently work in the best interests of the financial services industry, the very entities they are supposed to be regulating. Guardians of Finance: Making Regulators Work for Us, published in February by MIT Press, goes beyond telling us what went wrong. The authors also suggest reforms needed to prevent the next crisis.
