A group of scientists from Hawaiʻi, Brazil and California has measured the diameter of the Sun with unprecedented accuracy by using a spacecraft to time the transits of the planet Mercury across the face of the Sun in 2003 and 2006.
The measurements of the Sun’s size were made by University of Hawaiʻi at Mānoa Institute for Astronomy scientists Drs. Marcelo Emilio (visiting from Ponta Grossa, Brazil), Jeff Kuhn and Isabelle Scholl in collaboration with Dr. Rock Bush of Stanford University. They used the Michelson Doppler Imager (MDI) aboard NASA’s Solar and Heliospheric Observatory (SOHO) to make the measurements. (more…)
*Youths echo findings from International Youth Foundation report, which urges actions to help young people succeed.*
REDMOND, Wash. — March 27, 2012 — The numbers are staggering: Our planet has the largest youth population ever, with more than 1 billion people aged 15 to 24, and the figure is racing to 1.5 billion by 2035, according to “Opportunity for Action,” a new report being released today from the International Youth Foundation (IYF). The report shows that while some youths are succeeding, millions of others are not because they don’t have access to the necessary education, skills and opportunities.
Microsoft commissioned the “Opportunity for Action” report to bring attention to the urgency of the global youth opportunity divide — the gap between those who have access to a good education and the technology, skills and connections to be successful, and those who do not. No region of the world escapes the unsettling picture captured by the report. In Brazil, approximately 40 percent of firms have difficulty finding qualified staff to fill job vacancies due to low-quality education. In Asia, 70 percent of working youths are engaged in the agricultural sector, where jobs are seasonal and offer no protections or access to safety nets. And in sub-Saharan Africa, youths are grossly under-employed, leaving 72 percent of young people living on less than two dollars per day. (more…)
*Damaged deep-sea corals discovered months after Deepwater Horizon spill*
Scientists are reporting new evidence that the Deepwater Horizon oil spill has affected marine life in the Gulf of Mexico, this time species that live in dark ocean depths–deepwater corals.
The research used a range of underwater vehicles, including the submarine Alvin, to investigate the corals. The findings are published this week in the journal Proceedings of the National Academy of Sciences (PNAS). (more…)
Researchers from North Carolina State University have found that including ads in mobile applications (apps) poses privacy and security risks. In a recent study of 100,000 apps in the official Google Play market, researchers noticed that more than half contained so-called ad libraries. And 297 of the apps included aggressive ad libraries that were enabled to download and run code from remote servers – which raises significant privacy and security concerns.
“Running code downloaded from the Internet is problematic because the code could be anything,” says Dr. Xuxian Jiang, an assistant professor of computer science at NC State and co-author of a paper describing the work. “For example, it could potentially launch a ‘root exploit’ attack to take control of your phone – as demonstrated in a recently discovered piece of Android malware called RootSmart.” (more…)
EAST LANSING, Mich. — The huge changes in the Earth’s crust that influenced human evolution are being redefined, according to research published today in Nature Geoscience.
The Great Rift Valley of East Africa – the birthplace of the human species – may have taken much longer to develop than previously believed.
“We now believe that the western portion of the rift formed about 25 million years ago, and is approximately as old as the eastern part, instead of much younger as other studies have maintained,” said Michael Gottfried, Michigan State University associate professor of geological sciences. “The significance is that the Rift Valley is the setting for the most crucial steps in primate and ultimately human evolution, and our study has major implications for the environmental and landscape changes that form the backdrop for that evolutionary story.” (more…)
A genetic finding could help to explain why influenza becomes a life-threatening disease for some people, and yet has only a mild effect on others. Collaborative research led by scientists at UCL and the Wellcome Trust Sanger Institute found that people who carry a particular variant of the IFITM3 gene are significantly more likely to be hospitalised when they fall ill with influenza than those who carry other variants.(more…)
Study Highlights Importance of ‘Viewable Impressions’ and Need for Holistic View of Ad Delivery for Marketers to Maximize Digital and Cross-Media Campaigns
RESTON, VA, March 26, 2012 – comScore, Inc., a leader in measuring the digital world, today released full study results from its U.S.-based vCE Charter Study involving online advertising campaigns for 12 premium national advertisers. The study found that, in many cases, a large portion of ad impressions are not delivered according to plan, and that the quality of ad delivery can vary greatly based on a variety of factors, including site, placement, creative and targeting strategy.

Chickens can’t speak, but they can definitely make themselves heard. Most people who have visited a poultry farm will recall chicken vocalization – the technical term for clucking and squawking – as a memorable part of the experience.(more…)
