BEIJING, Sept. 14 (Xinhuanet) -- Facebook unveiled a new feature called "smart lists" on Tuesday, giving its users an easier way to share photos, posts and updates with smaller groups of friends.The new function, which commences on Wednesday, borrows from the success of the Circles feature of Google+, which allows users to categorize friends into groups.With the new feature, Facebook can automatically put your friends into groups, with the first four being work, school, family and city, based on the information of colleges, workplaces and geographic locations in users' profiles.The feature is optional to use, and the lists are customizable."This is really something we have been working on for four years," Facebook director of product management Blake Ross told AFP, adding "We think this is the way people will make lists going forward."In the meantime, the social networking site has also come up with "close friends" and "acquaintances" options.People can read the updates of their "close friends" more prominently in their news feed and just big news of their "acquaintances", according to Naomi Gleit, the director of product at Facebook who worked on the new feature.

CANBERRA, Sept. 1 (Xinhua) -- Bushranger Ned Kelly's headless body has finally been identified in Australia, more than 130 years after his execution in the Old Melbourne Gaol, Victoria's Attorney- General Robert Clark announced on Thursday.Clark said the bushranger's remains have been identified by doctors and scientists at the Victorian Institute of Forensic Medicine (VIFM).Kelly was an Irish Australian bushranger, considered by some merely a cold-blooded killer, while by others a folk hero and symbol of Irish Australian resistance against oppression by the British ruling class for his defiance of the colonial authorities. He was hanged for murder in 1880 at Old Melbourne Gaol. His daring and notoriety made him an iconic figure in Australian history, folklore, literature, art and film.The project involved collaboration with the ancient DNA laboratory EAAF in Argentina, which has worked with the VIFM on other forensic projects.Clark said "This is an extraordinary achievement by our forensic team here in Victoria," he told reporters in Melbourne on Thursday."To think a group of scientists could identify the body of a man who was executed more than 130 years ago, moved and buried in a haphazard fashion among 33 other prisoners, most of whom are not identified, is amazing." The investigation started when a skull believed to belong to Kelly was handed to the VIFM on Nov. 11, 2009.The skull handed in in 2009 was found not to be that of Ned Kelly, and Glenrowan historian Gary Deans said the next step is to find Kelly's skull."The Government should put a request in the public arena for the return of Ned Kelly's skull," he told ABC News."We know thanks to Jack Cranston, who held the skull around 1929, that it was sitting on a detective's desk. This was around the same time that remains were dug up in the Old Melbourne Gaol."I imagine that that detective or somebody else took it home."

CANBERRA, Sept. 23 (Xinhua) -- A genetic study on Friday found Aboriginal Australians are descended from the first people to leave Africa up to 75,000 years ago.Researchers from the University of Western Australia, Murdoch University and an international team analyzed genetic material of a 100-year-old West Australian Aboriginal man's hair, and found he was directly descended from a migration out of Africa into Asia.The study revealed that Australian Aboriginal ancestors split from the first modern human populations to leave Africa, between 64,000 and 75,000 years ago, at least 24,000 years before other human migrations.According to Dr. Joe Dortch, an archaeologist at the University of Western Australia, the discovery rewrites the history of the human species by confirming humans moved out of Africa in waves of migrations rather than in one single out-of-Africa diaspora.It also rewrites the story about how Aborigines arrived in Australia some 50,000 years ago."So far there are no [archaeological] sites that are over 50, 000 years old so it puts a time limit on that and focuses our future efforts," he said in a statement released on Friday.Dr. Dortch believes the finding will foster a sense of pride in modern Australian Aborigines."No-one else in the world can say 'I am descended from people who have been here 75,000 years'."Associate Professor Darren Curnoe, leader of the Human Evolutionary Biology Lab in the School of Biological, Earth & Environmental Sciences at the University of New South Wales, said the study powerfully confirms that Aboriginal Australians are one of the oldest living populations in the world, certainly the oldest outside of Africa."Australians are truly one of the world's great human populations and a very ancient one at that, with deep connections to the Australian continent and broader Asian region. About this now there can be no dispute," he told Xinhua in an email note.Meanwhile, Professor Alan Cooper, Director of the Australian Centre for Ancient DNA (ACAD) at the University of Adelaide, said while this is a major step forward, the key unresolved question remains the unique story of Aboriginal history within Australia, such as what has happened in those 50,000 years of life in the harsh Australian environment."Unfortunately, the information from a single individual tells us very little about this fascinating, and critically important part of human history. Aborigines are one of the oldest continuous human populations outside Africa, as they note in the paper, and due to the geographic isolation and limited archaeological records remain one of the most mysterious chapters in human history," he told Xinhua on Friday.The study is published on Friday in the journal Science.Indigenous Australians are the original inhabitants of the Australian continent and nearby islands. They together make up more than 2.5 percent of Australia's population.

BERLIN, June 8 (Xinhua) -- German health minister Daniel Bahr expressed cautious hope Wednesday for an end to the wave of E. coli infections as authorities reported two more deaths and more than 300 new cases."I can't give an all-clear, but after the analysis of the latest data we have reasons for hope, as the number of new infections is continuously dropping," Bahr told local public television ARD before an emergency meeting in Berlin with European Union Health Commissioner John Dalli."Unfortunately, there will be new cases and more deaths have to be expected, but overall new infections are clearly going down," he said.On the same day, Germany's national disease control center, the Robert Koch Institute, said the number of reported cases in Germany had risen by more than 300 to 2,648. Nearly 700 of those affected have been taken to hospital with a serious complication that can cause kidney failure.The Institute did not fully support Bahr's optimism. It said there was a declining trend in new cases but added it was not clear whether this was because the outbreak was truly waning or because consumers were staying away from the raw vegetables believed to be the source of the E. coli.The German government has faced increasing criticism from abroad and at home over its dealing with the crisis. It was twice wrong in naming the source of the outbreak and it has been criticized for a lack of coordination between research institutes.Dalli was quoted by local daily Die Welt as saying, "we have to rely on the experience and expertise across Europe, and even outside Europe."The Max Planck Institute for Infection Biology in Berlin also called for a federal government representative to coordinate the various government agencies dealing with the disease to eliminate mixed messages.

BEIJING, Sept. 27 (Xinhuanet) -- Last-minute preparations for the launch of the Tiangong-1 spacecraft began at the Jiuquan Satellite Launch Center on Monday, meaning the vehicle can soon embark on a mission that will eventually have it dock with a spaceship, according to the center.That feat, if carried out successfully, will mark the completion of China's first rendezvous and docking mission.At the launch site on Monday afternoon, crews were putting in place pipes and cables that will be used to inject fuel into the rocket that will carry Tiangong-1 into outer space.Without complications from the weather or other causes, the Long March II-F rocket will lift off from the launch center on Thursday or Friday, taking the Tiangong-1 with it, according to the Xinhua News Agency.Despite the preparations, space experts said carrying out the plan still comes with many risks. They explained that the spacecraft and much of the other equipment being used is new and has not been tried on an actual mission."Tiangong-1 is a brand new spacecraft designed by China and is bigger and heavier than the Shenzhou spaceships China had developed as a means of transporting astronauts from the Earth to space," said Yang Hong, chief designer of Tiangong-1.In a vertical position, the Tiangong-1 looks like a cigar standing 10.4 meter tall, a height equal to that of a three-story building. It weighs 8.5 tons and has a maximum diameter of 3.35 meters, a dimension shared by its launch vehicle, he said.In comparison, the Shenzhou spaceship stands shorter, at nearly 9 meters, is slimmer, having a diameter of less than 3 meters, and weighs less.In another difference, the Tiangong-1 is composed of two modules rather than the three that had made up the Shenzhou spaceship. Of the Tiangong-1's two primary components, one is an experimental module that contains a place that astronauts can live and work in on future missions. It is also equipped with a docking port.The other chief component, a resource module, will provide the craft with power.Astronauts on Tiangong-1 will have 15 cubic meters of space to move in, "much more than they had in the Shenzhou spaceship", Yang said.Inside the spacecraft are two sleeping sections with adjustable lighting systems, exercise equipment, entertainment systems and visual communication devices, he said.Hou Xiangyang, who helped design Tiangong-1, said: "The sleeping section is big enough for a 1.8-meter-tall man to sleep in. An astronaut can adjust the light as he likes."In space, Tiangong-1 will fly in a horizontal position. A paint scheme inside will help the astronauts aboard maintain their sense of direction; the module's inner walls will be in two colors, one commonly associated with the sky and one with the ground."This will help astronauts avoid feeling as if they are standing upside down in the microgravity environment," he said.Yang said the Tiangong-1 spacecraft is expected to stay in orbit for two years and rendezvous and dock with three different spaceships. Beyond the Shenzhou VIII, ships named Shenzhou IX and Shenzhou X will embark on similar missions; at least one of the two is to be manned.Before astronauts climb on board Tiangong-1, the conditions inside its experimental module will be adjusted to ensure they can live in an environment that contains enough oxygen, moisture and heat to be safe.Tiangong-1 was originally scheduled to be launched into a low orbit around the Earth between Sept 27 and 30. The earlier days were removed as possible launch dates, though, after forecasters predicted a cold air mass would move into the area containing the Jiuquan Satellite Launch Center.To ensure the spacecraft and Long March II-F carrier rocket are ready for launch, a full ground simulation was conducted on Sunday afternoon.
