WASHINGTON, Dec. 22 (Xinhua) -- The journal Science on Thursday chose the HPTN 052 clinical trial, an international HIV prevention trial as the 2011 Breakthrough of the Year.The study found that if HIV-infected heterosexual individuals begin taking anti-retroviral medicines when their immune systems are relatively healthy as opposed to delaying therapy until the disease has advanced, they are 96 percent less likely to transmit the virus to their uninfected partners. Findings from the trial, first announced in May, were published in the New England Journal of Medicine in August.The study was funded by the U.S. National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health."The HPTN 052 study convincingly demonstrated that anti- retroviral medications can not only treat but also prevent the transmission of HIV infection among heterosexual individuals," said NIAID Director Anthony Fauci in a statement. "We are pleased that Science recognized the extraordinary public health significance of these study results."Science's list of nine other ground-breaking scientific achievements from 2011 include:The Hayabusa Mission: After some near-disastrous technical difficulties and a stunningly successful recovery, Japan's Hayabusa spacecraft returned to Earth with dust from the surface of a large, S-type asteroid. This asteroid dust represented the first direct sampling of a planetary body in 35 years, and analysis of the grains confirmed that the most common meteorites found on Earth, known as ordinary chondrules, are born from these much larger, S-type asteroids.Unraveling Human Origins: Studying the genetic code of both ancient and modern human beings, researchers discovered that many humans still carry DNA variants inherited from archaic humans, such as the mysterious Denisovans in Asia and still-unidentified ancestors in Africa. One study this year revealed how archaic humans likely shaped our modern immune systems, and an analysis of Australopithecus sediba fossils in South Africa showed that the ancient hominin possessed both primitive and Homo-like traits.Capturing a Photosynthetic Protein: In vivid detail, researchers in Japan have mapped the structure of the Photosystem II, or PSII, protein that plants use to split water into hydrogen and oxygen atoms. The crystal-clear image shows off the protein's catalytic core and reveals the specific orientation of atoms within. Now, scientists have access to this catalytic structure that is essential for life on Earth -- one that may also hold the key to a powerful source of clean energy.Pristine Gas in Space: Astronomers using the Keck telescope in Hawaii to probe the faraway universe wound up discovering two clouds of hydrogen gas that seem to have maintained their original chemistry for two billion years after the big bang. Other researchers identified a star that is almost completely devoid of metals, just as the universe's earliest stars must have been, but that formed much later. The discoveries show that pockets of matter persisted unscathed amid eons of cosmic violence.

BEIJING, Oct. 27 (Xinhuanet) -- Virginia M. Rometty, 54, will succeed present IBM CEO Sam Palmisano to be the next chief executive at the start of 2012, the company announced Tuesday.This is unprecedented in the New York-based company's 100-year history, because Rometty, a senior vice president of IBM, will be its first female CEO.Since joining the company three decades ago, Ms. Rometty has contributed a lot to the giant I.T. Company.After graduating from Northwestern University with an undergraduate degree in computer science, she entered the company in 1981 as a systems engineer. In virtue of outstanding performance, she was quickly promoted to management.For the following 20 years, she worked with clients in banking, insurance, and telecommunications, to name a few.In 2002, Rometty caught Palmisano's attention when she helped integrate the 3.5 billion dollar acquisition of the big business consulting firm PricewaterhouseCoopers Consulting, IBM's largest deal ever at the time.Then she became senior vice president of the group and group executive for sales, marketing and strategy in 2009. Under her leading, the business in overseas emerging markets including China, India, Brazil and several African nations, has increased sharply.New York Times reported that such markets now accounted for 23 percent of IBM.’s revenue, up from 20 percent when she took over.“Ginni got it because she deserved it,” Mr. Palmisano told the New York Times. "Ginni" is an informal first name used by her friends and colleagues.The selection of Rometty for chief executive will make her the 17th female CEO in the Fortune 500 on the following January. Other prominent women who play the same role as Rometty include Indra Nooyi of PepsiCo, Ellen J. Kullman of DuPont, Meg Whitman of Hewlett-Packard, and so on.

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.
