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.

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.

BEIJING, Oct. 12 (Xinhuanet) -- People are often recommended to eat plenty of fruits and vegetables, but only a minority people take the advice. A new research may motivate more people to do so.BBC reported a new study Tuesday that found eating lots of vegetables and fruits can weaken the effect of a gene variant called 9p21, which is reported to be one of the strongest predictors for heart disease, thereby reducing risks of heart disease.The researchers from McMaster and McGill universities studied the diets of more than 27,000 people around the world, including Europe, China, and Latin America.They found that people with the high-risk gene appeared to have a similar risk of heart disease as people with a low-risk variant of that gene after consuming a diet with a healthy amount of vegetables and fruits.But how diet has such an effect on the gene was unknown, said Dr. Sonia Anand, a lead author of the study published in PLoS Medicine journal.Anand added, "Despite having a high genetic risk for heart disease, a healthy lifestyle can actually turn off the gene."The message here is very clear, eating plenty of vegetables and fruits is definitely good to people's heart health, according to BBC.

BANGKOK, Nov. 4 (Xinhua) -- Hundreds of Bangkok residents gathered in the city centre on Thursday, making ten thousand micro-organism balls to help clean the polluted water in flooded areas.Organized by local volunteer groups, the activity aimed to make 10,000 Effective Micro-organism balls (EM Ball), which are proven to be efficient in cleaning contaminated floodwater.According to Danal Chanchaochai, the organizer of the event, people in flooded areas were facing critical conditions as germs may spread in polluted water and threat their health. Mainly consist of soil, rice bran and micro-organisms, a tennis-sized EM Ball is capable to clean up 10 liter of water and can last for as long as one month, which making it a perfect water sanitizer.Another main objective of the event was to educate citizens on the simple steps of making EM Balls, in case of more flood in the city, he said.The organization had generated buzz on social media sites like facebook and twitter, calling everyone to help.Held at Amarin Plaza, one shopping mall at city centre, the activity attracted groups of volunteers, including office workers, local students and even foreign visitors.Volunteers were lining up to get the raw materials from the collection point and gave back completed EM Balls to the distribution centre in boxes. Residents needed to present their identity cards in order to retrieve the donated water cleaners.Volunteer Kulawan Ayura Chai said that, although her house hadn' t been affected by water yet, she understood the difficult situation faced by the victims and felt responsible to help.Lasted for three days from Thursday to Saturday, the activity aimed to make 100,000 EM Balls, adding to the 30,000 balls made earlier, to distribute to the flood victims in Bangkok and other regions in Thailand.

BEIJING, Nov. 1 (Xinhua) -- The ministers of Brazil, South Africa, India and China (BASIC) in a Tuesday joint statement urged developed nations to fulfill their commitments and provide funds and technology to help developing nations tackle climate change.Developed nations should honor their commitments, made at the Copenhagen climate change conference in 2009, to provide 100 billion U.S. dollars annually by 2020 and ensure that there will be no funding gaps from 2013 to 2020, according to the statement.Developed nations should also fulfill their pledge to offer 30 billion U.S. dollars in "fast-start funding" to developing nations in order to help them address climate change, the statement said.The ministers agreed that the coming Durban climate change conference should achieve a "comprehensive, fair and balanced outcome" under the principle of common but differentiated responsibility.They called on the conference to clearly establish the second commitment period under the Kyoto Protocol, during which developed country parties to the Kyoto Protocol should undertake quantified emission reduction commitments.The Kyoto Protocol is the cornerstone of climate change and its second commitment period is an essential priority for the success of the Durban conference, according to the statement.H The joint statement was issued following a two-day meeting of ministers from the four nations, also known as the ninth BASIC Ministerial Meeting on Climate Change, a mechanism through which the four countries and other developing countries coordinate their efforts in climate change.Representatives of Group 77 countries, island countries and the Arab League also attended the meeting.The Durban conference is scheduled for November. The focus of the conference is expected to be the extension of the Kyoto Protocol and acquiring a commitment from developed countries for the protocol's next period.The Kyoto Protocol, an international agreement linked to the United Nations Framework Convention on Climate Change, sets binding targets for 37 industrialized countries and the European community for reducing greenhouse gas emissions from 2008 to 2012.
