Acclaimed by her peers in the United States as “possibly the greatest woman scientist of the 20th century” and known in her native New Zealand as a “world leader in modern cosmology and one of the most creative and significant theoreticians in modern astronomy,” the late Yale astronomer Beatrice Tinsley has certainly earned a place in the annals of history.
Now she’s earned a place in the World Atlas as well. (more…)
*Scientists discover how “Didymo” algae bloom in pristine waters with few nutrients*
The pristine state of unpolluted waterways may be their downfall, according to research results published in a paper this week in the journal Geophysical Research Letters.
A species of freshwater algae that lives in streams and rivers, called Didymo for Didymosphenia geminata, is able to colonize and dominate the bottoms of some of the world’s cleanest waterways–precisely because they are so clear. (more…)
PASADENA, Calif. — Astronomers, including a NASA-funded team member, have discovered a new class of Jupiter-sized planets floating alone in the dark of space, away from the light of a star. The team believes these lone worlds were probably ejected from developing planetary systems.
The discovery is based on a joint Japan-New Zealand survey that scanned the center of the Milky Way galaxy during 2006 and 2007, revealing evidence for up to 10 free-floating planets roughly the mass of Jupiter. The isolated orbs, also known as orphan planets, are difficult to spot, and had gone undetected until now. The newfound planets are located at an average approximate distance of 10,000 to 20,000 light-years from Earth. (more…)
*Introduces industry-first tape library technology capable of storing nearly 3 exabytes of data — enough to store almost 3X the mobile data in U.S. in 2010*
ARMONK, N.Y., – 09 May 2011: IBM today announced new tape storage and enhanced archiving, deduplication offerings designed to help clients efficiently store and extract intelligence from massive amounts of data.
The amount of information generated is increasing dramatically each year driven by armies of sensors, mobile devices, social networks, cloud computing and public sources of information like the Web. At the same time, demand for storage capacity worldwide will continue to grow at a compound annual growth rate of 49.8 percent from 2009-2014, according to IDC (1). Clients require new technologies and ways to capitalize on the growing volume, variety and velocity of information known as “Big Data.” (more…)
*Males Spend 64 Percent More Time Viewing Online Video than Females*
*comScore Releases Latest Online Video Rankings for New Zealand*
Auckland, New Zealand, March 30, 2011 – comScore, Inc., a leader in measuring the digital world, today released its latest 
study of online video viewing habits in New Zealand based on data from the comScore Video Metrix service, which was launched in New Zealand earlier this year. The report found that 2.1 million online users in New Zealand watched online video in February 2011, representing 77 percent of the total online population. Google Sites led the market as the top online video property, driven largely by viewership at YouTube.com.
“Video viewing is an important and growing online activity for New Zealanders, with online viewers watching more than one video every day on average,” said Amy Weinberger, comScore vice president for Australia and New Zealand. “Online video offers an especially engaging experience for consumers that translates into the potential for high quality advertising impressions from desirable audiences that can be delivered at scale.” (more…)
It’s not just how free the market is. Some economists are looking at another factor that determines how much a country’s economy flourishes: how smart its people are. For a study published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science, researchers analyzed test scores from 90 countries and found that the intelligence of the people, particularly the smartest 5 percent, made a big contribution to the strength of their economies.
In the last 50 years or so, economists have started taking an interest in the value of human capital. That means all of the qualities of the people who make up the workforce. Heiner Rindermann, of the Chemnitz University of Technology, wanted to look more closely at human capital, and particularly the factor that psychologists call cognitive ability. “In other words, it’s the ability of a person to solve a problem in the most efficient way—not with violence, but by thinking,” Rindermann says. He wrote the new study with James Thompson of University College London. (more…)
GAINESVILLE, Fla. — Red imported fire ant invasions around the globe in recent years can now be traced to the southern U.S., where the nuisance insect gained a foothold in the 1930s, new University of Florida research has found.
Native to South America, the ant had been contained there and in the southeastern U.S. before turning up in faraway places in the last 20 years — including California, China, Taiwan, Australia and New Zealand. (more…)
No matter their size or shape, explosive volcanoes produce tremors at similar frequencies for minutes, days or weeks before they erupt. In the Feb. 24 issue of the journal Nature, researchers at Yale University and the University of British Columbia describe a model that explains this strange phenomenon — and may help forecast deadly eruptions.
When such volcanoes erupt they can shoot hot ash up to 40 kilometers into the atmosphere and cause devastating destruction when the ash column collapses and spreads as “pyroclastic flows”. Prior to most of these explosive eruptions the volcanoes shake slightly but measurably, and the shaking becomes more dramatic during the eruption itself. This tremor is one of the primary precursors and warnings used by volcanologists for forecasting an eruption. (more…)
