SAN FRANCISCO, Nov. 17 (Xinhua) -- Online retail giant Amazon is working on a smartphone scheduled to be released in the fourth quarter of 2012, U.S. media reported Thursday.A note from Citigroup analyst Mark Mahaney obtained by technology news site All Things Digital said that based on the supply chain checks in Asia, Amazon is believed to launch a smartphone in the fourth quarter of 2012.According to the note, Amazon is working with manufacturer Foxconn and the device will run Texas Instruments' OMAP 4 processor. The Kindle Fire, the latest tablet introduced by the e- commerce giant, also uses OMAP processor.The analyst said the smartphone will cost Amazon between 150 and 170 U.S. dollars to build and the company could sell the handset at or near its cost rather than a 30 percent gross margin like many other smartphone manufacturers usually do.The move is expected to further intensify Amazon's rivalry with Apple and Google after the e-commerce giant had made moves on some booming businesses like tablet computer and cloud-computing service.

BEIJING, Oct. 24 (Xinhuanet) -- There is no evidence to prove that using a cell phone can increase the risks of brain cancer, suggested a lastest study by Danish researchers.To arrive at the result, the researchers examined the health records from 1990 to 2007 for 358,403 Danish cell phone plan subscribers.They found that among people using cell phones for as long as 13 years or more, the cancer risks were almost the same as for non-subscribers.The finding, published in the British Medical Journal last week, alleviated the fear among the world's 5 billion cell phone users.Five months ago, a statement from the World Health Organization's International Agency for Research on Cancer (IARC) sparked fear in cell phone users around the world because it said that cell phone use might cause brain cancer.However, the finding could not rule out the risk of brain cancer triggered by heavy use of cell phones, admitted Patrizia Frei of the Danish Cancer Society's Institute of Cancer Epidemiology, lead author of the study.Frei added, cited by CNN, "There are still some open questions, about greater amounts of use, and about the effects on children."The IARC did not give formal response to the study, but it offered some ways for cell phone consumers to reduce possible risks months ago.Texting and using hands-free sets for voice calls lower exposure to potentially harmful radiation, compared to device-to-ear voice calls, by at least 10-fold, IARC stated, reported by the New York Daily News.

SAN FRANCISCO, Nov. 28 (Xinhua) -- Amazon.com on Monday announced that this past Black Friday was the best ever for its Kindle products with consumers buying four times as many Kindle e- readers and tablets as they did last year.According to the online retail giant, its newly launched tablet Kindle Fire was the bestselling product across all of Amazon.com on Black Friday, the day after Thanksgiving, which falls on Nov. 25 this year, when major retailers in the United States traditionally offer big discounts.Kindle Fire is Amazon's answer to Apple's popular iPad. Priced at 199 U.S. dollars, the Amazon product is much cheaper than iPad which starts from 499 dollars.Survey results by research firm ChangeWave Research released days before Black Friday indicated that Amazon is poised to become the No. 2 player in the tablet computer market behind Apple, due to strong demand for Kindle Fire.Amazon said Black Friday sales also showed that a lot of customers were buying multiple Kindles, one for themselves and others as gifts.The trend is expected to continue through this holiday shopping season, Amazon's vice president of Kindle products Dave Limp said in a statement.

ISLAMABAD, Oct. 15 (Xinhua) -- President Asif Ali Zardari said on Saturday that the government was committed to address the issues of special people including those afflicted with impaired vision and blindness and called for establishing highest standards for their care.In a message on the International White Cane Safety Day, the President asked the people and relevant government agencies to reflect on the problems of visually handicapped people.He asked them to come up with suggestions to achieve high standards in caring for the disabled as these exist in other civilized nations.The White Cane Safety Day was aimed at creating awareness about the problems and requirements of visually handicapped persons and to take practical steps to address these issues.

WASHINGTON, Dec. 5 (Xinhua) -- NASA's Kepler mission has confirmed its first planet in the "habitable zone," a region where liquid water could exist on a planet's surface, the U.S. space agency announced on Monday.The newly-confirmed planet, Kepler-22b, is the smallest yet found to orbit in the middle of the habitable zone of a star similar to Sun. The planet is about 2.4 times the radius of Earth. Scientists don't yet know if Kepler-22b has a predominantly rocky, gaseous or liquid composition, but its discovery is a step closer to finding Earth-like planets.Previous research hinted at the existence of near-Earth-size planets in habitable zones, but clear confirmation proved elusive. Two other small planets orbiting stars smaller and cooler than Sun recently were confirmed on the very edges of the habitable zone, with orbits more closely resembling those of Venus and Mars.Kepler-22's star is a bit smaller than our sun, so its habitable zone is slightly closer in. The diagram shows an artist's rendering of the planet comfortably orbiting within the habitable zone, similar to where Earth circles the sun. Kepler-22b has a yearly orbit of 289 days. The planet is the smallest known to orbit in the middle of the habitable zone of a sun-like star. It's about 2.4 times the size of Earth."This is a major milestone on the road to finding Earth's twin, " said Douglas Hudgins, Kepler program scientist at the NASA Headquarters in Washington. "Kepler's results continue to demonstrate the importance of NASA's science missions, which aim to answer some of the biggest questions about our place in the universe."Kepler discovers planets and planet candidates by measuring dips in the brightness of more than 150,000 stars to search for planets that cross in front, or "transit," the stars. Kepler requires at least three transits to verify a signal as a planet."Fortune smiled upon us with the detection of this planet," said William Borucki, Kepler principal investigator at the NASA Ames Research Center who led the team that discovered Kepler-22b. "The first transit was captured just three days after we declared the spacecraft operationally ready. We witnessed the defining third transit over the 2010 holiday season."The Kepler science team uses ground-based telescopes and the Spitzer Space Telescope to review observations on planet candidates the spacecraft finds. The star field that Kepler observes in the constellations Cygnus and Lyra can only be seen from ground-based observatories in spring through early fall. The data from these other observations help determine which candidates can be validated as planets.Kepler-22b is located 600 light years away. While the planet is larger than Earth, its orbit of 290 days around a Sun-like star resembles that of Earth. The planet's host star belongs to the same class as Sun, called G-type, although it is slightly smaller and cooler.Of the 54 habitable-zone planet candidates reported in February 2011, Kepler-22b is the first to be confirmed. This finding will be published in The Astrophysical Journal.
