EAST LANSING, Mich. — By mating with nearly 100 males, queen bees on isolated islands avoid inbreeding and keep colonies healthy.
The results, published in the current issue of PLoS ONE, focused on giant honey bee colonies on Hainan Island, off the coast of China. Since these bees have long been separated from their continental cousins, it was thought that the island bees would be prime candidates for inbreeding as well as having very different genes, said Zachary Huang, Michigan State University entomologist.

*Media & Entertainment Providers Must Practice New Rules for Engagement, Digitizing Content is Not Enough*
ARMONK, N.Y. – 16 Apr 2012: A new IBM study of the media and entertainment market, reveals that as consumers adopt an increasing number of digital devices, four distinct new “digital personalities” are emerging. This shift is compelling companies to adopt more innovative business models that deliver personalized experiences. (more…)
New research by UCLA life scientists could lead to predictions of which plant species will escape extinction from climate change.
Droughts are worsening around the world, posing a great challenge to plants in all ecosystems, said Lawren Sack, a UCLA professor of ecology and evolutionary biology and senior author of the research. Scientists have debated for more than a century how to predict which species are most vulnerable.
Sack and two members of his laboratory have made a fundamental discovery that resolves this debate and allows for the prediction of how diverse plant species and vegetation types worldwide will tolerate drought, which is critical given the threats posed by climate change, he said. (more…)
A new assessment of wind energy in India by Lawrence Berkeley National Laboratory has found that the potential for on-shore wind energy deployment is far higher than the official estimates— about 20 times and up to 30 times greater than the current government estimate of 102 gigawatts. This landmark finding may have significant impact on India’s renewable energy strategy as it attempts to cope with a massive and chronic shortage of electricity.
“The main importance of this study, why it’s groundbreaking, is that wind is one of the most cost-effective and mature renewable energy sources commercially available in India, with an installed capacity of 15 GW and rising rapidly,” says Berkeley Lab scientist Amol Phadke, the lead author of the report. “The cost of wind power is now comparable to that from imported coal and natural gas-based plants, and wind can play a significant role in cost effectively addressing energy security and environmental concerns.” (more…)
How do we understand what’s happening today by looking back millions of years?
Scientists are looking at what climate conditions were like 3.3 to 3 million years ago, during a geologic period known as the Pliocene, and they are confident in the accuracy of their data.
The Pliocene is the most recent period of sustained global warmth similar to what is projected for the 21st century. Climate during this time period offers one of the closest analogs to estimate future climate conditions. (more…)
Russia was ready to sign a contract with China to supply 48 multi-role Su-35 fighter jets. However, Russia put forward a condition to the Celestial Empire. Moscow demands guarantees that the aircraft will not be further copied for sale.
According to Kommersant, the amount of the expected transaction could reach $4 billion, or approximately $85 million per unit. If the contract is signed, it will be the largest arms contract of the last decade.(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…)
