*University of Minnesota professor is part of international team that predicts the volatile region’s water may once again vanish*

MINNEAPOLIS / ST. PAUL — An international team of scientists drilling deep under the bed of the Dead Sea has found evidence that the sea may have dried up during a past warm period similar to predicted scenarios for climate change in coming decades. Emi Ito, professor of earth sciences in the University of Minnesota’s College of Science and Engineering, is a research team member. (more…)

NASA Finds Japan Tsunami Waves Merged, Doubling Power

PASADENA, Calif. – NASA and Ohio State University researchers have discovered the major tsunami generated by the March 2011 Tohoku-Oki quake centered off northeastern Japan was a long-hypothesized “merging tsunami.” The tsunami doubled in intensity over rugged ocean ridges, amplifying its destructive power at landfall.

Data from NASA and European radar satellites captured at least two wave fronts that day. The fronts merged to form a single, double-high wave far out at sea. This wave was capable of traveling long distances without losing power. Ocean ridges and undersea mountain chains pushed the waves together along certain directions from the tsunami’s origin.

A U physicist will help determine if neutrinos can outrace light

Back in 2007, a physics experiment clocked elusive subatomic particles called neutrinos going faster than light.

That wasn’t supposed to happen. If the speed of light in a vacuum—denoted “c” by physicists—isn’t the universal speed limit, it would mean that Einstein put the wrong number in his famous E=mc² equation.

University of Minnesota physicist Marvin Marshak was part of the experiment, called MINOS. It clocked beams of neutrinos shot from Fermilab, a national physics lab near Chicago, to a detector 457 miles away in the Soudan Underground Laboratory in northern Minnesota. (more…)

Relationships More Important than Genetic Ties When Deciding Who Cares for Aging Family Members, MU Researchers Say

*Divorce and remarriage affect beliefs about who should care for elder relatives*

COLUMBIA, Mo. – America’s elderly population will nearly double by 2050, according to a Pew Research report. As baby boomers enter retirement, concern exists as to who will care for them as they age. Traditionally, children have accepted the caregiving responsibilities, but those caregiving roles are becoming blurred as more families are affected by divorce and remarriage than in previous decades. Now, University of Missouri researchers have found that relationship quality trumps genetic ties when determining caregiving obligations.

Lawrence Ganong, a professor and co-chair in the MU Department of Human Development and Family Studies in the College of Human Environmental Sciences (HES), studied how divorce and remarriage affect beliefs about who should care for aging relatives. He found that relationship quality, a history of mutual help, and resource availability influence decisions about who cares for parents and stepparents. (more…)

BERKELEY, CA — Saul Perlmutter, an astrophysicist at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and a professor of physics at the University of California at Berkeley, has won the 2011 Nobel Prize in Physics “for the discovery of the accelerating expansion of the universe through observations of distant supernovae.” Perlmutter heads the international Supernova Cosmology Project, which pioneered the methods used to discover the accelerating expansion of the universe, and he has been a leader in studies to determine the nature of dark energy.

Perlmutter shares the prize with Brian Schmidt and Adam Riess, leader of the High-z Supernova Search Team and first author of that team’s analysis, respectively, which led to their almost simultaneous announcement of accelerating expansion. (more…)

NASA Leads Study of Unprecedented Arctic Ozone Loss

PASADENA, Calif. – A NASA-led study has documented an unprecedented depletion of Earth’s protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere.

The study, published online Sunday, Oct. 2, in the journal Nature, finds the amount of ozone destroyed in the Arctic in 2011 was comparable to that seen in some years in the Antarctic, where an ozone “hole” has formed each spring since the mid-1980s. The stratospheric ozone layer, extending from about 10 to 20 miles (15 to 35 kilometers) above the surface, protects life on Earth from the sun’s harmful ultraviolet rays. (more…)

*comScore Releases Visitation View of Leading Global Retail and Auction Sites*

Reston, VA, August 17, 2011 – comScore, Inc., a leader in measuring the digital world, today released a report on selected global retail and auction sites based on data from the comScore Media Metrix service. The study found that of the destinations analyzed, Amazon Sites reached the largest global audience with more than 282 million visitors in June, or 20.4 percent of the worldwide Internet population. Other top brands in the study included eBay, which reached 16.2 percent of global Internet visitors, China’s Alibaba.com Corporation (11.3 percent reach), Apple.com Worldwide Sites (9.7 percent reach) and Japan’s Rakuten Inc. (4.2 percent reach).

“While retail e-commerce has already grown to become a $150+ billion annual industry in the U.S., it still presents enormous upside opportunity across much of the globe,” said Gian Fulgoni, comScore co-founder and chairman. “Technology has changed the way consumers behave, and increasingly they are opting for the convenience and pricing advantages offered by the online channel. Several global retail brands have already capitalized on this global consumer trend, and many other retailers are sure to pursue their share of the pie.” (more…)
