Knight, an economist at Brown University and Yosh Halberstam, an economist at the University of Toronto analysed nearly 500,000 communications during the 2012 US elections in a social network of 2.2 million politically-engaged Twitter users. They found that both conservatives and liberals were disproportionately exposed to like-minded information. PTI LONDON: Led by a team of scientists of Indian-origin, NASA’s Curiosity rover has found new evidence of water on Mars, indicating that the planet most like Earth in the solar system was suitable for microbial life.
Pictures and other data collected by NASA’s Mars rover Curiosity show that rivers once flowed into a lake or lakes at the bottom of Gale Crate, an enormous dimple carved out by an incoming space rock.
NASA said its interpretation of Curiosity’s finds in Gale Crater suggests ancient Mars maintained a climate that could have produced long-lasting lakes at many locations on the Red Planet. The American space agency said Mars’s Mount Sharp was built by sediments deposited in a large lake bed over tens of millions of years.
“If our hypothesis for Mount Sharp holds up, it challenges the notion that warm and wet conditions were transient, local, or only underground on Mars,” said Indian- American Ashwin Vasavada, Curiosity deputy project scientist at NASA’s Jet Propulsion Laboratory in Pasadena. PTI
