*Facebook Audience Triples in the Past Year while Engagement Grows Nearly Sevenfold*

São Paulo, Brazil, January 17, 2012 – comScore, Inc., a leader in measuring the digital world, today released data showing that Facebook assumed the top position in the Brazilian social networking market following a year of exceptional growth. In December 2011, Facebook.com attracted 36.1 million visitors – representing an increase of 192 percent in the past twelve months – to surpass Orkut as the leading social networking destination in the market.

“Facebook’s rapid ascent in the Brazilian market has certainly been one of the most interesting stories to develop during the course of 2011,” said Alex Banks, comScore managing director for Brazil. “Brazil has always been a particularly social market and currently owns the fifth largest social networking population in the world. But despite the cultural affinity for social media, Facebook adoption had traditionally lagged in the market. That has all changed in the past year, during which the site has tripled in audience size as engagement has grown sevenfold to assume the leadership position in the market.” (more…)

New Take on Impacts of Low Dose Radiation

*Berkeley Lab Researchers Find Evidence Suggesting Risk May Not Be Proportional to Dose at Low Dose Levels*

Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab), through a combination of time-lapse live imaging and mathematical modeling of a special line of human breast cells, have found evidence to suggest that for low dose levels of ionizing radiation, cancer risks may not be directly proportional to dose. This contradicts the standard model for predicting biological damage from ionizing radiation – the linear-no-threshold hypothesis or LNT – which holds that risk is directly proportional to dose at all levels of irradiation.

“Our data show that at lower doses of ionizing radiation, DNA repair mechanisms work much better than at higher doses,” says Mina Bissell, a world-renowned breast cancer researcher with Berkeley Lab’s Life Sciences Division. “This non-linear DNA damage response casts doubt on the general assumption that any amount of ionizing radiation is harmful and additive.” (more…)

UChicago Chemist Helps Craft Message For World Leaders

Dmitri Talapin, associate professor in chemistry, was one of 10 young scientists from around the world who delivered a message that “Scientific Research is a Global Necessity” to political, scientific and business leaders participating in the 2011 Science and Technology in Society forum last October in Kyoto, Japan.

The Japan Society for the Promotion of Science and the New York Academy of Sciences selected Talapin to represent the young scientists of North America at the STS Forum, which meets at the same venue were the Kyoto Protocol to alleviate global warming was signed in 1997. (more…)

Fast Times in Physics

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…)
