EAST LANSING, Mich. — A year after Japan was struck by triple disasters – earthquake, tsunami and nuclear meltdown – many citizens cannot find regular work and face the possibility of never returning to their homes and seeing their communities disappear, according to a Michigan State University scholar.
Ethan Segal, associate professor of Japanese history, made two trips to Japan following the March 11, 2011, catastrophe, spending close to two weeks in the northeastern part of the country that was most directly affected. (more…)
*Report Offers Insights on the Mobile and Connected Device Landscape in 2011 and What They Mean for 2012*
RESTON, VA, February 23, 2012 – comScore, Inc., a leader in measuring the digital world, today released the 2012 Mobile Future in Focus report. This annual report examines the mobile and connected device landscape, covering several mobile markets measured by comScore, through an exploration of key trends driving smartphone adoption growth, mobile media usage in categories such as social networking and retail, mobile ecosystem dynamics, and shifts in multi-device digital media consumption in 2011. The report highlights insights primarily from mobile markets in the United States, France, Germany, Italy, Spain, United Kingdom, Japan, and Canada. (more…)
In the effort to convert sunlight into electricity, photovoltaic solar cells that use conductive organic polymers for light absorption and conversion have shown great potential. Organic polymers can be produced in high volumes at low cost, resulting in photovoltaic devices that are cheap, lightweight and flexible.
In the last few years, much work has been done to improve the efficiency with which these devices convert sunlight into power, including the development of new materials, device structures and processing techniques. (more…)
*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…)
*Females influence the gender of their offspring so they inherit either their mother’s or grandfather’s qualities. ‘High-quality’ females – those which produce more offspring – are more likely to have daughters.*
*Weaker females, whose own fathers were stronger and more successful, produce more sons.*
The study, by scientists at the University of Exeter (UK), Okayama University and Kyushu University (Japan), is published today (9 January) in the journal Ecology Letters. It shows for the first time that females are able to manipulate the sex of their offspring to compensate for the fact that some of the genes which make a good male make a bad female and vice versa.
The research focuses on the broad-horned flour beetle, Gnatocerus cornutus, but the team believes the findings could apply to other species across the animal kingdom, even mammals. (more…)
*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…)
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.
