WASHINGTON, Aug. 11 (Xinhua) -- The unique fossils of an adult plesiosaur and its unborn baby may provide the first evidence that these ancient animals gave live birth like mammals, according to a new study to be published Friday in the journal Science.The 78-million-year-old, 15.4-foot-long (4.7-meter-long) adult specimen is a Polycotylus latippinus, one of the giant, carnivorous, four-flippered reptiles that lived during the Mesozoic Era.Dr. Robin O'Keefe of Marshall University in West Virginia and Dr. Luis Chiappe, Dinosaur Institute director of the Natural History Museum in Los Angeles County, have determined that it is the fossil of an embryonic marine reptile contained within the fossil of its mother.The embryonic skeleton contained within shows much of the developing body, including ribs, 20 vertebrae, shoulders, hips, and paddle bones.O'Keefe and Chiappe have also determined that plesiosaurs were unique among aquatic reptiles in giving birth to a single, large offspring, and that they may have lived in social groups and engaged in parental care.Although live birth has been documented in several other groups of Mesozoic aquatic reptiles, no previous evidence of it has been found in the important order of plesiosaurs."Scientists have long known that the bodies of plesiosaurs were not well suited to climbing onto land and laying eggs in a nest," O'Keefe said."So the lack of evidence of live birth in plesiosaurs has been puzzling. This fossil documents live birth in plesiosaurs for the first time, and so finally resolves this mystery."

BRUSSELS, May 31 (Xinhua) -- A deadly outbreak of E.coli linked to contaminated cucumbers is sending Europe on high alert, as death toll from the disease climbed to 16 till Tuesday.So far, 15 people have reportedly died and more than 300 were seriously ill from infections linked to tainted vegetables in Germany. Experts said the numbers are expected to increase in the coming week."We hope the number of cases will go down but we fear it will worsen," said Oliver Grieve, spokesperson with the University Medical Center Schleswig where most German victims are being treated.The German government has identified the pathogen as hemolytic-uremic syndrome (HUS), a serious complication of a type of E. coli known as Shiga toxin-producing E.coli (STEC). The bacteria could damage blood cells and kidneys, and hence cause deaths.A woman in her 50s was confirmed to be the first fatal victim out of Germany by a local hospital on Tuesday. Officials at the hospital in Boras, southwestern Sweden, said the woman, who had recently traveled to Germany, was admitted on May 29.Swedish health authorities already said on Sunday that 36 people, all linked to travel in northern Germany, had been confirmed to have infected with E.coli, whereas cases were also reported in France, the Netherlands, Denmark and Britain.It was the second food scare for European consumers this year. In January, highly toxic dioxin was found in eggs, poultry and pork products across Germany.

LONDON, Sept. 22 (Xinhua) -- A British publisher on Thursday issued an "unauthorized autobiography" of the founder of the controversial Wikileaks website Julian Assange.Assange became a global figure after he published 250,000 secret United States diplomatic cables on his Wikileaks website, which became a serious embarrassment to the American government.He was then accused by two women of rape when he was in Sweden. Swedish police said they wanted to question him, and issued a European Arrest Warrant in 2010 for him.Assange, 40, denies the allegations and surrendered himself to police in London at the end of 2010, and the Swedish authorities applied for his extradition to face questioning.Assange fought the extradition bid in the English courts, fearing that he could face further extradition from Sweden to the United States where he could face criminal charges related to the publishing of the secret cables, but failed.He appealed against the extradition ruling in July and a final decision on the case will be made by senior English judges, probably before Christmas.Assange agreed to cooperate with Edinburgh-based publisher Canongate in publishing an autobiography and had 50 hours of interviews with a ghostwriter between January and March this year, while he was on bail awaiting an outcome of the extradition hearings.He received a 500,000 pound advance (about 768,000 U.S. dollars) for the book.Publisher's spokesman Liz Sich told Xinhua Thursday, "It's an unauthorized autobiography -- it is his words. He was contracted to write his autobiography in December; a ghostwriter was assigned to it, approved by the publisher and Julian and an intense amount of work was done in the first three months of 2011. The first draft was delivered on schedule at the end of March. After that there was an hiatus and nothing happened; in June Julian decided he wanted to tear up the contract."Assange has opposed publication, but Sich said, "It is very much Julian's words, it is written in the first person. He didn't want it to be published but he was in breach of his contract. He couldn't pay the advance back because he had used it to pay his lawyers."The book is available only in English at the moment, but a Dutch publisher and a Turkish publisher said they would print translations in their languages, and other foreign language editions are also likely.

BEIJING, Sept. 14 (Xinhuanet) -- Scientists had discovered the fossils of a new species of ancient carnivorous fish, National Geographic reported Monday.The newly-found ancient fish, "Laccognathus embryi", is a 1.8-meter-long predator, which was "waiting to lunge out to grab whatever was in front of it," said study co-author Ted Daeschler, a vertebrate zoologist at the Academy of Natural Sciences in Philadelphia, the U.S..It had a jaw filled with sharp teeth that were 1.5 inches long, the Journal of Vertebrate Paleontology described.The fish lived in the Devonian period, 415 to 360 million years ago, which "was a fish-eats-fish kind of world," Daeschler said. "There was a real arms race going. If you didn't have good armor on your body, you were very vulnerable.""It's not just finding the animal - it's also placing the animal in its evolutionary crucible," Daeschler added.Its closest living relative is the lungfish which can survive in the drought, scientists said.Scientists hope the finding can help in their study on the revolution of fishes as well as other species.

LOS ANGELES, July 5 (Xinhua) -- NASA's Juno spacecraft is 30 days away before its first launch window opens, the Jet Propulsion Laboratory (JPL) announced on Tuesday."One month from today, our first launch window opens at 11:34 a. m. EDT (8:34 a.m. PDT) and lasts 69 minutes," said Jan Chodas, Juno project manager from NASA's JPL in Pasadena, Los Angeles."Our primary launch period is 22 days long, and so if weather or other issues come up on Aug. 5, we have 21 more days to get Juno flying. Once we get Juno into space, it's a five-year cruise to Jupiter.""The launch window is the length of time allotted every day for an attempt to launch the spacecraft," said Chodas. "The launch period is the period of time in days when everything is in the right place to get your mission off to the right start."For a mission like Juno, getting everything in the right place includes considering the size of the rocket and spacecraft, where our home planet -- and in particular Juno's launch pad -- is pointed at any moment, and its location in space relative to other celestial objects like Juno's final target, Jupiter.Juno is scheduled to launch aboard a United Launch Alliance Atlas V rocket from pad 41-C at the Cape Canaveral Air Force Station, Florida.The solar-powered spacecraft will orbit Jupiter's poles 33 times to find out more about the gas giant's origins, structure, atmosphere and magnetosphere and investigate the existence of a solid planetary core.JPL manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute in San Antonio.The Juno mission is part of the New Frontiers Program managed at NASA's Marshall Space Flight Center in Huntsville, Alaska. Lockheed Martin Space Systems, Denver, built the spacecraft.
