Apple working on iPhone that could be unlocked by ‘owner’s fingerprint’

London: Apple is reportedly working on a new technology that would let phone to be unlocked by the owner’s fingerprint, a report has said. Apple is said to be planning to introduce an iPhone that can be unlocked by the owner’s fingerprint. At the same time other manufacturers are thought to be experimenting with iris scanning and voice recognition, the Telegraph reports. According to the paper, speculation about Apple’s plans for fingerprint recognition began last year when the iPhone maker bought biometric security firm AuthenTec for 235 million pounds. Earlier this month, KGI Securities analyst Ming-Chi Kuo said his firm expected the results of that takeover to be revealed this year with the new iPhone 5S. Samsung has had a “Face Unlock” feature in its phones since last year’s Galaxy S3. However, the phone’s camera would often unlock if it recognised a photograph of the owner. The firm said the feature has been improved in the Galaxy S4, released in New York last week. ANI...

Youngest-known supernova remnants discovered

Washington: NASA’s Swift satellite has uncovered the previously unknown remains of a shattered star while performing an extensive X-ray survey of our galaxy’s central regions. Designated G306.3-0.9 after the coordinates of its sky position, the new object ranks among the youngest-known supernova remnants in our Milky Way galaxy. “Astronomers have previously cataloged more than 300 supernova remnants in the galaxy,” lead scientist Mark Reynolds, a postdoctoral researcher at the University of Michigan in Ann Arbor said. “Our analysis indicates that G306.3-0.9 is likely less than 2,500 years old, making it one of the 20 youngest remnants identified,” he said. Astronomers estimate that a supernova explosion occurs once or twice a century in the Milky Way. The expanding blast wave and hot stellar debris slowly dissipate over hundreds of thousands of years, eventually mixing with and becoming indistinguishable from interstellar gas. A wider view places G306.3-0.9 in context with star-formation regions in southern Centaurus. Like fresh evidence at a crime scene, young supernova remnants give astronomers the best opportunity for understanding the nature of the original star and the details of its demise. Supernova remnants emit energy across the electromagnetic spectrum, from radio to gamma rays, and important clues can be found in each energy band. X-ray observations figure prominently in revealing the motion of the expanding debris, its chemical content, and its interaction with the interstellar environment, but supernova...

Samsung’s Galaxy S4 emerges to do battle on Apple’s home turf

New York: Samsung Electronics is intensifying its rivalry with Apple with its new Galaxy S4 smartphone, which has a larger, sharper screen than its predecessor, the best-selling S III. Samsung trumpeted the much-anticipated phone’s arrival Thursday. The Galaxy S4, which crams a 5-inche (127-millimeter) screen into a body slightly smaller than the S III’s, will go on sale in the US sometime between the end of April and the end of June. Samsung plans to offer the Galaxy S4 through 327 carriers in 155 countries, giving it a wider reach than Apple’s iPhone 5. Samsung didn’t say what the phone will cost, but it can be expected to start at $200 with a two-year contract in the US That’s comparable to the iPhone 5. JK Shin, the executive in charge of Samsung’s mobile communications division, promised the money would be well spent for a “life companion” that will “improve the way most people live every day.” That bold promise set the tone for the kind of flashy presentation associated with the showmanship of Apple, the company that Samsung has been trying to upstage. JK Shin, president and head of IT and mobile communications for Samsung Electronics, presents the new Samsung Galaxy S4 during the Samsung Unpacked event in New York.

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...
