The flip of a single molecular switch helps create the mature neuronal connections that allow the brain to bridge the gap between adolescent impressionability and adult stability. Now Yale School of Medicine researchers have reversed the process, recreating a youthful brain that facilitated both learning and healing in the adult mouse. (more…)
Antarctica’s topography began changing from flat to fjord-filled starting about 34 million years ago, according to a new report from a University of Arizona-led team of geoscientists.
Knowing when Antarctica’s topography started shifting from a flat landscape to one with glaciers, fjords and mountains is important for modeling how the Antarctic ice sheet affects global climate and sea-level rise. (more…)
Microsoft BizSpark startup improves communication and provides easy access to administrative resources combined with an educational social network.
REDMOND, Wash. — March 7, 2013 — During a trip to his home town in St. Petersburg, Russia, Gabriel Levi noticed that his local school system could modernize its services for educators and students by streamlining communication and reducing manual tasks. Using his entrepreneurial instincts, he saw a need and created a solution. Now Levi is CEO and founder of Classed In, where he has turned his mission into a thriving business with a comprehensive educational social network that connects teachers, students, administrators and parents at approximately 27,000 K–12 schools in Russia — more than half the country’s schools.
Levi attended college at Columbia University in New York and studied economics and computer science, while he dreamed of starting a business. When a work assignment took him back to St. Petersburg a few years later, he was struck by how Russian schools were still relying on completely manual processes for everything from registration and grade reporting to class assignments and homework. His point of reference was personal: Levi’s mother was a university instructor, and his younger brother was in middle school at the time. (more…)
Oculoplastic surgeons at the Yale Eye Center perform a range of procedures, from Botox injections to fix wrinkles, to lifesaving surgeries to help treat cancers near the eye.
(March 2013) Gail Chiasson’s “puffy eyelids” had gotten so heavy she felt as if they’d become permanently half-shut. Not only did she look sleepy, she felt sleepy. She couldn’t read a book for long and grew especially concerned when a doctor trying to perform an eye test had to tape her lids out of the way. (more…)
A University of Washington research team has captured color photographs of what could be a previously undocumented species of chambered nautilus, a cephalopod mollusk often classified as a “living fossil,” in the waters off American Samoa in the South Pacific. (more…)
Newt Gingrich described for the audience at a recent University of Chicago Institute of Politics event the shock he felt when he realized last Election Day that President Obama would win re-election, confounding Gingrich’s predictions and hopes.
Gingrich said he and his wife Callista stared at each other in disbelief as they took in exit polls and then voting returns that showed a loss beyond anything he had feared, especially among Senate races in traditionally Republican states. It led Gingrich to take a hard look at the tactical and technological gap that may have contributed to his party’s loss. (more…)
Comet 2013 A1 (Siding Spring) will make a very close approach to Mars in October 2014.
The latest trajectory of comet 2013 A1 (Siding Spring) generated by the Near-Earth Object Program Office at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., indicates the comet will pass within 186,000 miles (300,000 kilometers) of Mars and there is a strong possibility that it might pass much closer. The NEO Program Office’s current estimate based on observations through March 1, 2013, has it passing about 31,000 miles (50,000 kilometers) from the Red Planet’s surface. That distance is about two-and-a-half times that of the orbit of outermost moon, Deimos.
Scientists generated the trajectory for comet Siding Spring based on the data obtained by observations since October 2012. Further refinement to its orbit is expected as more observational data is obtained. At present, Mars lies within the range of possible paths for the comet and the possibility of an impact cannot be excluded. However, since the impact probability is currently less than one in 600, future observations are expected to provide data that will completely rule out a Mars impact. (more…)
New Microsoft-commissioned study also highlights dangers for those that use counterfeit software.
REDMOND, Wash. — Although some computer users may actively seek pirated software in hopes of saving money, the chances of infection by unexpected malware are one in three for consumers and three in 10 for businesses, according to a new study commissioned by Microsoft Corp. and conducted by IDC. As a result of these infections, the research shows that consumers will spend 1.5 billion hours and US$22 billion identifying, repairing and recovering from the impact of malware, while global enterprises will spend US$114 billion to deal with the impact of a malware-induced cyberattack.
The global study analyzed 270 websites and peer-to-peer networks, 108 software downloads, and 155 CDs or DVDs, and it interviewed 2,077 consumers and 258 IT managers or chief information officers in Brazil, China, Germany, India, Mexico, Poland, Russia, Thailand, the United Kingdom and the United States. Researchers found that of counterfeit software that does not come with the computer, 45 percent comes from the Internet, and 78 percent of this software downloaded from websites or peer-to-peer networks included some type of spyware, while 36 percent contained Trojans and adware.
