MeRAM is up to 1,000 times more energy-efficient than current technologies
By using electric voltage instead of a flowing electric current, researchers from UCLA’s Henry Samueli School of Engineering and Applied Science have made major improvements to an ultra-fast, high-capacity class of computer memory known as magnetoresistive random access memory, or MRAM. (more…)
Researchers from North Carolina State University have created conductive wires that can be stretched up to eight times their original length while still functioning. The wires can be used for everything from headphones to phone chargers, and hold potential for use in electronic textiles. (more…)
A Yale scientist and colleagues in Britain have found a highly unusual ancient marine fossil that retains soft body parts as well as its shell, including limbs, eyes, gills and alimentary system. The fossil represents a new species of ostracod, a tiny crustacean related to crabs, lobsters and shrimps.
“Fossil ostracods often provide evidence of the relative ages of the rocks in which they occur, but it is very difficult to determine their relationship to living forms because only the shell is normally preserved,” said Derek E. G. Briggs, director of Yale’s Peabody Museum of Natural History and a co-author of the research. “This 425-million-year-old new form is remarkable in preserving the limbs and other anatomical features as well.” (more…)
Analysis of Social Networking in Latin America Shows LinkedIn Grabbing #2 Position with35 Million Monthly Visitors
Santiago, Chile, December 20, 2012 – comScore, a leader in measuring the digital world, today released an analysis of social networking activity 
in Latin America, which found that Argentina and Brazil led as the most engaged social networking markets worldwide with visitors spending an average of near 10 hours on social networking sites in November 2012. The study also found that LinkedIn, which has grown strongly in the past year due to both organic growth and the acquisition of Slideshare.net, is now the second most visited social network in Latin America.

Russian President Vladimir Putin started his large press conference at midday, December 20th. The conference brought together more than 1,200 Russian and foreign journalists.
The head of state started with statistics. According to him, the growth of GDP in January-October of this year made up 3.7 percent. According to Vladimir Putin, this is a good result. Recession in the world economy (and in particular in the euro area) became an obstacle for reaching better results, as well as a poor harvest in Russia. Last year, more than 90 million tons of grain were collected. This year, the harvest has dropped to 74 million tons. (more…)
More than half a million adults in California seriously thought about committing suicide during the previous year, according to a new study from the UCLA Center for Health Policy Research.
The study, which uses data from the 2009 California Health Interview Survey (CHIS), is the first by the center to focus on suicide ideation.
In California, suicide is the 10th leading cause of death, the researchers noted. An average of nine deaths by suicide occur each day in the state. (more…)
A surprising number of microorganisms – more than 100 times more kinds than reported just four months ago – are leaping the biggest gap on the planet. Hitching rides in the upper troposphere, they’re making their way from Asia across the Pacific Ocean and landing in North America.
For the first time researchers have been able to gather enough biomass in the form of DNA to apply molecular methods to samples from two large dust plumes originating in Asia in the spring of 2011. The scientists detected more than 2,100 unique species compared to only 18 found in the very same plumes using traditional methods of culturing, results they published in July. (more…)
COLUMBUS, Ohio – A new study provides the first experimental evidence that the negative effects of playing violent video games can accumulate over time.
Researchers found that people who played a violent video game for three consecutive days showed increases in aggressive behavior and hostile expectations each day they played. Meanwhile, those who played nonviolent games showed no meaningful changes in aggression or hostile expectations over that period. (more…)
