SAN FRANCISCO, Nov. 1 (Xinhua) -- Yahoo, which has been rumored to sell all or part of its business, announced on Tuesday that it is buying data-driven advertising network Interclick for around 270 million U.S. dollars.Interclick is a technology company providing data targeted solutions and optimization technologies."This investment underscores our focus on enhancing the performance of both our guaranteed and non-guaranteed display business across Yahoo and our partner sites and, combined with Yahoo's reach and advertising leadership, will deliver a powerful solution for marketers," said Ross Levinsohn, Yahoo's executive vice president for the Americas region.Some analysts said Interclick's technology could help Yahoo to grow its display advertising market share as Google and Facebook have gained on or surpassed the company in the area.But the acquisition also raised questions considering Yahoo's financial situation after it reported last month its revenue in the last quarter decreased by 5 percent year-over-year. The company is also in a chief executive officer (CEO) search following the firing of former CEO Carol Bartz in September and amidst reports of a possible takeover.Although in a financial struggle, Yahoo still has around 700 million unique monthly visitors and its news division is the biggest online news site with around 81.2 million unique visitors in August.Tech giants like Google and Microsoft are reported to be considering providing finance for the acquisition of Yahoo by another company or a group of companies.In a report on Monday, Bloomberg News reported that Yahoo is leaning toward selling Asian assets and redistributing the proceeds to shareholders, rather than selling itself to a group of buyers. Yahoo's shares fell more than 5 percent after the possibility was reported.

BEIJING, Oct. 20 (Xinhuanet) -- British scientists used bacteria and DNA to build basic components for digital devices in a new research, according to media reports, suggesting biological computers come closer to reality.Digital devices are based on logic gates, fundamental building blocks in silicon circuitry, said Professor Richard Kitney, leading researcher of the research published in the journal Nature Communications, "Without them, we could not process digital information."According to Science Daily, Professor Kitney and his colleagues from the Imperial College London replicated the building blocks using bacteria and DNA, forming biological logic gates, which paved the way for building more complex biological processors in the future.The researchers hoped biological computers can be applied to monitoring human health in the future.They believed that small biological processors, inserted in human bodies, could roam inside the bodies, monitor the health, and correct any problems they found.These biological logic gates are the most advanced created by scientists. But there is still a long way to go to apply them in reality, said Professor Kitney.

SAN FRANCISCO, Oct. 7 (Xinhua) -- The funeral for Apple co-founder Steve Jobs, who died Wednesday at the age of 56, is taking place on Friday, U.S. media reported.The funeral is termed as a small private gathering, The Wall Street Journal quoted a person familiar with the matter as saying.The source would not disclose where or when the event was taking place, citing respect for Jobs and his family's privacy.Apple said it has no public services planned for Jobs. In an e- mail sent to Apple staff on Wednesday, Chief Executive Officer Tim Cook said "a celebration of Steve's extraordinary life" would be held soon for employees.On its website, Apple has encouraged people to send their memories and condolence to a special e-mail address.Meanwhile, online magazine deadling.com reported Friday that Sony Pictures is making a hefty deal to acquire feature rights to "Steve Jobs," the only authorized biography of the Apple co- founder which will be published on Oct. 24.

WASHINGTON, Nov. 10 (Xinhua) -- Using its near-infrared vision to peer nine billion years back in time, NASA's Hubble Space Telescope has uncovered an extraordinary population of young dwarf galaxies brimming with star formation, the U.S. space agency announced on Thursday.While dwarf galaxies represent the most common type of galaxy in the universe, the rapid star-birth observed in these newly- found examples may force astronomers to reassess their understanding of the ways in which galaxies form.The galaxies are a hundred times less massive, on average, than the Milky Way, yet they churn out stars at such a furious pace that their stellar content would double in just 10 million years. By comparison, the Milky Way would take a thousand times longer to double its star population.The universe is estimated to be 13.7 billion years old, and these newly-discovered galaxies are extreme even for the young universe -- when most galaxies were forming stars at higher rates than they are today. Astronomers using Hubble's instruments could spot the galaxies because the radiation from young, hot stars has caused the oxygen in the gas surrounding them to light up like a bright neon sign."The galaxies have been there all along, but up until recently astronomers have been able only to survey tiny patches of sky at the sensitivities necessary to detect them," said Arjen van der Wel of the Max Planck Institute for Astronomy in Germany, lead author of a paper on the results to be published online on Nov. 14 in The Astrophysical Journal. "We weren't looking specifically for these galaxies, but they stood out because of their unusual colors. "The observations were part of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS), an ambitious three- year study to analyze the most distant galaxies in the universe. CANDELS is the first census of dwarf galaxies at such an early epoch."In addition to the images, Hubble has captured spectra that show us the oxygen in a handful of galaxies and confirmed their extreme star-forming nature," said co-author Amber Straughn at NASA's Goddard Space Flight Center. "Spectra are like fingerprints. They tell us the galaxies' chemical composition."The CANDELS team uncovered the 69 young dwarf galaxies in near- infrared images taken with Hubble's Wide Field Camera 3 and Advanced Camera for Surveys.The observations suggest that the newly-discovered galaxies were very common nine billion years ago. However, it is a mystery why the newly-found dwarf galaxies were making batches of stars at such a high rate.

BEIJING, Nov. 13 (Xinhua) -- China has established an operation committee for management of the country's first space lab module, Tiangong-1, during its two-year orbit of earth.The committee will deal with operations planning, technical appraisal and flight control of the target orbiter after the unmanned Shenzhou-8 spacecraft returns to earth after its mission, the official website of China's manned space program said.The Tiangong-1 space lab module was launched on Sept. 29 and docked with Shenzhou-8 precisely on Nov. 3, China's first ever space docking attempt. The second docking between Tiangong-1 and Shenzhou-8 is scheduled for Nov. 14.The manned space program said earlier that the same target orbiter Tiangong-1 will accommodate another two docking missions performed by two other Shenzhou spaceships, at least one of which will be manned.The 8.5-tonne Tiangong-1 is the first space lab module that China has built, and the committee will also be the first in taking care of a long-running space asset.The operation committee for Tiangong-1 heralds China's manned space program entering a new phase for lengthy flight missions, Niu Hongguang, director of the operation committee, said on the website www.cmse.gov.cn.The orbiting module management will include taking care of the space lab, making preparations for any further docking tests and gathering experience for building a future space station, Niu said.
