SAN FRANCISCO, Dec. 13 (Xinhua) -- Apple is in talks to acquire Israeli fabless semiconductor maker Anobit for 400 million to 500 million U.S. dollars, U.S. media reported on Tuesday.Apple is likely interested in Herzliya Pituach, Israel-based Anobit for an exclusive access to its embedded flash controllers which can significantly boost memory performance of smartphones and tablet computers, said technology news site TechCrunch, citing Calcalist, an Israeli newspaper in Hebrew which first reported the possible acquisition.Apple already uses Anobit's technology in iPhone, iPad and the MacBook Air.If the deal works out, it could be Apple's largest acquisition ever, surpassing its 404 million-dollar purchase of NeXT in 1997.It could also become Apple's first acquisition in Israel and the first with Tim Cook as the chief executive officer of the company since its iconic leader Steve Jobs passed away in early October.

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.

WASHINGTON, Oct. 6 (Xinhua) -- The U.S. Food and Drug Administration (FDA) and the National Institutes of Health (NIH) announced Thursday a joint, large-scale, national study of tobacco users to monitor and assess the behavioral and health impacts of new government tobacco regulations.The initiative is the first large-scale NIH/FDA collaboration on tobacco regulatory research since the U.S. Congress granted FDA the authority to regulate tobacco products in an act in 2009. Scientists at NIH's National Institute on Drug Abuse and the FDA's Center for Tobacco Products will coordinate the effort."The launch of this study signals a major milestone in addressing one of the most significant public health burdens of the 21st century," said FDA Commissioner Margaret Hamburg in a statement. "The results will strengthen FDA's ability to fulfill our mission to make tobacco-related death and disease part of America's past and will further guide us in targeting the most effective actions to decrease the huge toll of tobacco use on our nation's health."Investigators will follow more than 40,000 users of tobacco- product and those at risk for tobacco use ages 12 and older. They will examine what makes people susceptible to tobacco use; evaluate use patterns and resulting health problems; study patterns of tobacco cessation and relapse in the era of tobacco regulation; evaluate the effects of regulatory changes on risk perceptions and other tobacco-related attitudes; and assess differences in attitudes, behaviors and key health outcomes in racial-ethnic, gender, and age subgroups."We are pleased to collaborate with the FDA on this study that may provide us with a better understanding of the impact of product regulation on tobacco prevention and cessation," said NIH Director Francis Collins.While smoking rates have dropped significantly since their peak in the 1960s, nearly 70 million Americans ages 12 and older were current users of tobacco products in 2010. As a result, death and disease caused by tobacco use is still a tremendous public health burden. Tobacco use is the leading preventable cause of disease, disability, and death in the United States. Cigarette smoking results in more than 443,000 premature deaths in the United States each year -- more than alcohol, illegal drug use, homicide, suicide, car accidents, and AIDS combined.
