...first glance, data often seem to support the premise that there's an educational advantage to living in an owned home. Numbers from the U.S. Department of Education, for instance, show that elementary school students who live in owned homes consistently do better on reading and math tests than students who live in rentals. In a survey involving more than 20,000 children, first-graders in owned homes scored an average 77.3 points on a test of reading, while children in rented homes scored an average 68.5 points. That gap persisted for math scores (62.6 vs. 54.8), as well...
...platform. Marketers have access to the entire database of tweeters and can select whom they want to pay and how much they're willing to dish out. Compensation is based on a user's expertise or passion, how many followers that person has and other metrics, like how often the tweeter's followers click to links posted on his or her Twitter page. Murphy says he has paid more than $100,000 to Twitter users in his site's first month of operation. As commission, he charges companies 15% to 50% of their payments to the microbloggers.

...would kids who take more risks turn out to have more adultlike white matter than other kids? The authors suggest that some risk-taking among adolescents is evidence that they are trying out more adultlike roles.

"Adolescents who engage in [risky] behaviors obtain more experience in a variety of domains," the authors write. "Their more conservative peers, in contrast, do not have as much 'life...
...this question by drug-testing the 91 research subjects. Only nine had actually done drugs - in each case, marijuana - but eight of those nine admitted their drug use in the survey. No students who tested negative falsely claimed to have tried drugs. The teen brain, it appears, can be often an honest thing - even if it's not always a wise...
...published last month. Its writing, etched in signs on tiny, intricate seals and tablets, remains undeciphered, shrouding the ancient culture in mystery. A code-busting artifact with bilingual text, like the Rosetta stone, has yet to be found. By some counts, more than 100 decipherments of the civilization's often anthropomorphic runes and signs - known in the field as the Harappan script - have been attempted over the decades, none with great success. Some archaeologists spied parallels with the cuneiform of Mesopotamia. Others speculated an unlikely link between Harappan signs and the similarly inscrutable "bird-men" glyphs found thousands of miles...
