Mars could have once supported a habitable environment: NASA

Washington: An analysis of rock samples collected by the Curiosity rover indicates that Mars could have supported living microbes, the American space agency NASA has said. “A fundamental question for this mission is whether Mars could have supported a habitable environment. From what we know now, the answer is yes,” Michael Meyer, lead scientist for NASA’s Mars Exploration Program told reporters yesterday. Scientists identified sulphur, nitrogen, hydrogen, oxygen, phosphorus and carbon — some of the key chemical ingredients required to support life — in the powder Curiosity drilled out of a sedimentary rock near an ancient stream bed in Gale Crater on the Red Planet last month. “The range of chemical ingredients we have identified in the sample is impressive, and it suggests pairings such as sulfates and sulfides that indicate a possible chemical energy source for micro-organisms,” said Paul Mahaffy, principal investigator of the SAM suite of instruments at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Curiosity, a six-wheeled robot with 10 scientific instruments on board, is the most sophisticated vehicle ever sent to another planet. The data indicate that the Yellowknife Bay area, which the rover is exploring was the end of an ancient river system or an intermittently wet lake bed that could have provided chemical energy and other favourable conditions for microbes. The rock is made up of a fine grain mudstone containing clay...

China Wants to Talk With US About Cyber Security

By Terril Yue Jones Beijing: China offered on Tuesday to talk with the United States about cyber security amid an escalating war of words between the two sides on computer hacking, but suspicion is as deep in Beijing as it is in Washington about the accusations and counter-accusations. The world’s two leading economies have been squaring off for months over the issue of cyber attacks, each accusing the other of hacking into sensitive government and corporate websites. A U.S. computer security company said last month that a secretive Chinese military unit was likely behind a series of hacking attacks mostly targeting the United States. On Monday, U.S. National Security Advisor Tom Donilon called on China to acknowledge the scope of the problem and enter a dialogue with the United States on ways to establish acceptable behavior. China, in response, said it was happy to talk. “China is willing, on the basis of the principles of mutual respect and mutual trust, to have constructive dialogue and cooperation on this issue with the international community including the United States to maintain the security, openness and peace of the Internet”, Foreign Ministry spokeswoman Hua Chuying said at a daily news briefing. “Internet security is a global issue. In fact, China is a marginalized group in this regard, and one of the biggest victims of hacking attacks,” she added, echoing a common refrain...

Electric cars not doing so well

Geneva: After being the starring act for several years, the electric car backed into the shadows at this year’s International Geneva Motor Show as carmakers grow weary of waiting for sales to take off. Electric vehicles were not completely absent from the showrooms as the 83rd edition of the Geneva show kicked off, but no new models were unveiled and car company executives on site for the media days on Tuesday and Wednesday barely mentioned them. “Public confidence (in electric) has really fallen since its peak at the Paris show in 2010, when we only talked electric,” BIPE analyst Clement Dupont-Roc told AFP. Back then, French carmaker Renault, which leads the electric market, opened the order books for its first electric models and chief executive Carlos Ghosn said he expected the cars to represent 10% of the market by 2020. Renault’s compatriot PSA also plunged into the space, as did Japan’s Nissan with its Leaf. Sales have fallen short But as things stand today, sales have fallen far short of expectations. In France, which claims to be the leading market in Europe for electric, less than 6 000 new such vehicles were registered last year. The low volumes are part of the explanation for the weak offering on display in Geneva, but there are other issues as well. “There are three tasks we have to overcome when it comes...

New looks of facebook news feed announced

Facebook announced on Thursday a substantial redesign of its News Feed, the front page that users see when they access the service. Mark Zuckerberg described the new News Feed as a “personalized newspaper” that is more visual and allows users to choose the topics they’re most interested in. The images and links to articles are bigger, making it easier to see on mobile screens. “This design reflects the evolving face of News Feed,” Mr. Zuckerberg said at a news conference at the company’s headquarters here in Silicon Valley. The redesign does not change anything about the filtering algorithm that Facebook uses to select what shows up on a user’s News Feed. But users will now be able to drill down into topic-specific news feeds – one for music, another for photos, another for the publications, celebrities or brands they follow. That choice is aimed at addressing a concern raised by advertisers and content publishers like news sites: under the old system, it was difficult for their followers to see everything the companies have posted. The redesigned News Feed was clearly inspired by the ubiquity of cellphones, particularly in how easy they make taking and sharing photos online. Mr. Zuckerberg said half of all posts on the News Feed now are pictures, up from 25 percent a year ago. The pictures will show up bigger in the new feed. Facebook...
