EAST LANSING, Mich. — Countries that best prepare math teachers meet several key conditions generally lacking in the United States, according to the first international study of what teacher preparation programs are able to accomplish.
The study, led by Michigan State University, suggests that in countries such as Taiwan and Singapore, future math teachers are better prepared because the students get rigorous math instruction in high school; university teacher-preparation programs are highly selective and demanding; and the teaching profession is attractive, with excellent pay, benefits and job security.

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…)
Sitting Prime Minister Vladimir Putin won the presidential election in Russia. He received the votes from 63.82 percent of electors, who took part in the voting on March 4th.

Mikhail Prokhorov takes the third place with 7.77 percent. Vladimir Zhirinovsky comes next with 6.23 percent. Sergei Mironov comes last with only 3.84 percent. (more…)
PASADENA, Calif. — Astronomers using data from NASA’s Spitzer Space Telescope have, for the first time, discovered buckyballs in a solid form in space. Prior to this discovery, the microscopic carbon spheres had been found only in gas form in the cosmos.
Formally named buckminsterfullerene, buckyballs are named after their resemblance to the late architect Buckminster Fuller’s geodesic domes. They are made up of 60 carbon atoms arranged into a hollow sphere, like a soccer ball. Their unusual structure makes them ideal candidates for electrical and chemical applications on Earth, including superconducting materials, medicines, water purification and armor. (more…)
*Findings further efforts to better predict geomagnetic storms in space*
UCLA researchers have explained the puzzling disappearing act of energetic electrons in Earth’s outer radiation belt, using data collected from a fleet of orbiting spacecraft.
In a paper published Jan. 29 in the advance online edition of the journal Nature Physics, the team shows that the missing electrons are swept away from the planet by a tide of solar wind particles during periods of heightened solar activity. (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…)
A hemispherewide phenomenon – and not just regional forces – has caused record-breaking amounts of freshwater to accumulate in the Arctic’s Beaufort Sea.
Frigid freshwater flowing into the Arctic Ocean from three of Russia’s mighty rivers was diverted hundreds of miles to a completely different part of the ocean in response to a decades-long shift in atmospheric pressure associated with the phenomenon called the Arctic Oscillation, according to findings published in the Jan. 5 issue of Nature.

Latest indications are this relatively small comet has broken into even smaller, even less significant, chunks of dust and ice. This trail of piffling particles will remain on the same path as the original comet, completing its unexceptional swing through the inner solar system this fall.
“Elenin did as new comets passing close by the sun do about two percent of the time: It broke apart,” said Don Yeomans of NASA’s Near-Earth Object Program Office at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. “Elenin’s remnants will also act as other broken-up comets act. They will trail along in a debris cloud that will follow a well-understood path out of the inner solar system. After that, we won’t see the scraps of comet Elenin around these parts for almost 12 millennia.”(more…)
