BERLIN, Aug. 28 (Xinhua) -- Mercedes-Benz, the world leading luxury car producer, celebrates the 125th anniversary of its invention of automobile with what it claimed the largest gathering ever, at the former Tempelhof airport in Berlin on the weekend.The Mercedes-Benz Club and Mercedes-Benz enthusiasts greet visitors with some 1,800 well-assorted Mercedes-Benz-branded vehicles, ranging from vintage and classic passenger cars to a variety of historic commercial vehicles, on a vast open areas of 250,000 square metres of the abandoned Tempelhof airport, which was closed in 2008.It took Mr. Lauritzen and his wife two days' drive of their cherised wecker of Mercedes-Benz Cabriolet B. 320.W 142.-3,4l to reach here for taking part in the pageant."It is a long journey, but we are happy to be here to see more class cars and more friends with same interests," Mrs Lauritzen said.Owners take the opportunity to present their lovingly cared-for vehicles, which include a number of truly rare items of automotive history, to the Berlin public.The couple of Mr. Kerner drove their red Mercedes-Benz 170Dba, a made-in-1952 model with a range of special and unique designs which are very rarely seen now, over journey of 155 km from Bitterfeld to join in the gala."I'm fond of driving my classic car of Benz," said Mrs Kerner, despite it can run maximally at a speed of 50 to 80 km per hour, "but I truly enjoy the diesel engine sounds and the historic feeling it evokes."The legendary Silver Arrows, dating from the 1930s and 1950s, are also presented from the Mercedes-Benz Classic collection for demonstration drives."The brilliant history of the Silver Arrows will be brought to life with a demonstration of their impressive engine sound and incredible driving dynamics," said Michael Bock, head of Mercedes-Benz Classic and Director of Mercedes-Benz Museum GmbH."It is not often that these racing cars are driven in public, so this will be a true highlight of the program of events in Tempelhof."During the grand show, visitors are also accessible to first-hand experiences of the latest technologies applicable in the future for in passenger cars, commercial vehicles and racing cars."Some 125 years ago, Carl Benz submitted his patent application for the Benz Patent Motor Car to the Patent Office in Berlin", the organizer appealed to the visitors, saying now Mercedes-Benz is returning to Berlin to celebrate together with Berliners.

WASHINGTON, July 10 (Xinhua) -- U.S. space shuttle Atlantis docked with the International Space Station on Sunday morning after nearly two days of flight.Commander Christopher Ferguson guided space shuttle Atlantis to a docking with the station at 11:07 a.m. EDT (1507 GMT) when the two spacecrafts were flying 240 miles up over east of New Zealand, according to NASA.This was the 12th and final time Atlantis docked to the space station. It was the 46th shuttle docking to a space station, nine to the Russian Mir station and 37 to the International Space Station.The space shuttle Atlantis is seen with part of the structure of the International Space Station in the foreground and the earth in the background as it approaches the station for docking in this still image from NASA TV July 10, 2011. The shuttle and station crews will open hatches and hold the traditional welcome ceremony at about 1:19 p.m. EDT (1719 GMT). The combined crew of 10 will begin more than a week of docked operations, transferring vital supplies and equipment to sustain station operations once the shuttles are retired.Atlantis lifted off on Friday morning from Kennedy Space Center in Florida, on the 135th and final flight in NASA's shuttle program.It is the 33rd voyage for Atlantis. Its return to the earth later this month will mark the end of the 30-year shuttle program.

LOS ANGELES, June 24 (Xinhua) -- Near-Earth asteroid 2011 MD will whip past Earth on June 27, but will not pose any threat, NASA's Jet Propulsion Laboratory (JPL) said on Friday.The asteroid will pass only 12,000 kilometers (7,500 miles) above the Earth's surface at about 9:30 EDT, according to JPL in Pasadena, Los Angeles.This small asteroid, only 5-20 meters in diameter, is in a very Earth-like orbit about the Sun, but an orbital analysis indicates there is no chance it will actually strike Earth on Monday, JPL said.If a rocky asteroid the size of 2011 MD were to enter Earth's atmosphere, it would be expected to burn up high in the atmosphere and cause no damage to Earth's surface, said JPL.The accompanying diagram gives a view of the asteroid's trajectory from the general direction of the Sun. This view indicates that 2011 MD will reach its closest Earth approach point in extreme southern latitudes (in fact over the southern Atlantic Ocean), according to JPL. The incoming trajectory leg passes several thousand kilometers outside the geosynchronous ring of satellites and the outgoing leg passes well inside the ring, JPL said.For a brief time, it may be bright enough to be seen even with a modest-sized telescope.One would expect an object of this size to come this close to Earth about every six years on average.The asteroid was discovered by the LINEAR near-Earth object discovery team observing from Socorro, New Mexico.

CANBERRA, Sept. 6 (Xinhua) -- A rare virus that can be contracted by humans has killed a large number of Victorian pigeons after being detected in the Australian state for the first time, Agriculture Department confirmed on Tuesday.According to the Australian Chief Veterinary Officer, Dr Mark Schipp, the avian paramyxo virus has already started killing some hobby birds, and threatens to spread to Victoria's chicken population.He said the affected birds have died suddenly in large numbers and have sometimes appeared tired or have shown neurological signs such as circling or head flicking before death.He added that the bug can also cause conjunctivitis or influenza-like symptoms in humans."The virus causes only mild, short-term conjunctivitis or influenza-like symptoms (in humans)," Australia Associated Press quoted Schipp as reporting on Tuesday."Human infection with this virus is extremely rare and usually occurs only in people who have close direct contact with infected birds."At this stage, there are no reports of the virus causing disease in wild birds, but the Australian Wildlife Health Network has been asked to monitor the situation.

HONG KONG, July 19 (Xinhua) -- A gene controlled by male hormone was critical for the growth of liver tumor, leading to a higher incidence of the disease in men than in women, according to the Chinese University of Hong Kong which made the results public on Tuesday.There is a significant gender bias in liver cancer incidence. In Hong Kong, men are three times more likely to develop liver cancer than women. Such phenomenon prompted researchers from the university to carry out a genomic location analysis in liver cancer cells starting from 2008.The researchers discovered, out of 17,000 human genes, that a gene called Cell Cycle-Related Kinase (CCRK) was directly controlled by androgen receptor. They further found that CCRK was critical for the induction of signaling pathway leading to abnormal liver cell growth and tumor formation.The results also reveal that 70 percent of patients with liver cancer were found to produce high levels of CCRK. More importantly, these patients were more likely to have late-stage cancers and lived shorter than those with low CCRK level.Using mouse models, the researchers found that either lowering the level or blocking the signaling pathway of CCRK in liver cancer cells could significantly reduce the tumor growth rate.The study has validated that CCRK is an important gene that has potential to cause liver cancer and the gene can be tested as a new targeted therapy in future.Vice-Chancellor of the university Joseph Sung, who is also team leader of the research project, said the results explained why men have a higher risk of liver cancer than women and helped push ahead with the development of a novel treatment of the disease.The above study results were published online in July in Journal of Clinical Investigation.
