coastline in the U.S. State of California sampled by the state water board harbored fish with mercury in such high concentrations that they shouldn't be eaten by young women and children, a newly released survey has found.Fourteen percent of locations had similarly elevated levels of PCBs, according to the survey published by The Los Angeles Times on Sunday.The most elevated concentrations of mercury and PCBs were found in San Francisco Bay and San Diego Bay, said the survey funded by the state water board.The findings, part of a two-year inquiry that is the largest statewide survey of contaminants in sport fish along the California coast, examined more than 2,000 fish from three dozen species gathered in 2009 from waters near Los Angeles, San Francisco and San Diego, the paper said.The survey highlights the health problem of lingering mercury, a poisonous metal that is found in fish globally, and of PCBs, toxic chemicals the United States banned in the 1970s, the report said.Both substances continue to pose a risk to people who eat fish caught along the California coast because they can lead to nervous system damage and developmental problems in children and can cause cancer, liver damage and reproductive harm, the report quoted researchers as saying."Unfortunately, we're not seeing many areas that are totally clean," said Jay Davis, a senior scientist for the San Francisco Estuary Institute and lead author of the study. But a catalog of where and in what fish the substances abound should help anglers make better choices, Davis said. "With good information, people can reduce their exposure significantly."Sharks had some of the highest levels of mercury because of their unusual tendency to accumulate contaminants in their flesh, while chub mackerel had the lowest levels of contamination, according to the survey.The survey results were used in part to help craft new fish consumption guidelines issued earlier this week for anglers in San Francisco Bay, the first update there by state health officials in 17 years. The advisory identifies shiner perch and other surf perches as unsafe to eat in any quantity and warns young women and children not to eat white sturgeon, striped bass and sharks caught in the bay, The Times said.The buildup of metals and other chemicals in fish is such a problem along the Southern California coast that health officials two years ago expanded the number of fish species on the "do not eat" list from one to five because of high levels of PCBs, mercury and the banned pesticide DDT, the report noted.
BEIJING, June 14 (Xinhuanet) -- A biographical comic book of Apple's CEO Steve Jobs will hit the shelves in August, according to media reports Tuesday. Titled "Steve Jobs: Co-Founder of Apple", the 32-page comic book, which details the life and career of Jobs, will be published by Bluewater Productions Inc. "His innovations command front page news, speculation of his health affects the stock market. Not bad for a college dropout," Bluewater president Darren Davis said in a statement. "His story, and that of Apple, is epic." Apple CEO Steve Jobs.The book, priced at 3.99 U.S. dollars, was written by C.W. Cooke and drawn by Chris Schmidt. The publisher's intention to make Jobs as its subject came from the success of the comic biography of Facebook founder Mark Zuckerberg. "There are definitely some similarities between Zuckerberg and Jobs. It takes a certain kind of drive and a certain kind of genius to move society the way they have," said C.W. Cooke. In addition, the first authorized biography of Jobs, "iSteve: The Book of Jobs", will be released on March 6, 2012.

BEIJING, Sept. 26 (Xinhuanet) -- One of the world's brightest minds aims to bring to the world a new, advanced three-dimensional image technology that will leave other such technology in the shadows."Our new technology will be better than that used in Avatar," says Professor Yau Shing-tung of Harvard University."The image will be more vivid than with technologies used in previous movies. The new technology is not only quicker but cheaper."Yau is one of the world's greatest mathematicians, having won the prestigious Fields Medal. He was once the dean of the department of mathematics at Harvard, and is now a professor there. He is also a visiting professor at Tsinghua University.Professor Yau and his team met professionals from Tsinghua University and Renmin University of China last week, and they discussed possible cooperation to apply the technology in making a demonstration movie using the new technology.Yau and a team started working on the new 3D technology, founded on geometrical principles, at Harvard 10 years ago.What marks it out is the extremely vivid pictures it produces.3D technology is used not only in making movies and in Internet games but in other areas , such as medicine. Movie audiences the world over were awestruck by the technology used in the movie Avatar."After I watched the movie, all I could say was 'Wow'," said Shen Yiren, an IT staff worker in Zhongguancun Science and Technology Park Zone. "3D technology has extended the boundaries of the human imagination."Yau says that six years ago the makers of Avatar had wanted him to cooperate with them but he turned them down."I was not sure that (Avatar) would be such a big success."Avatar's facial caption technology puts points on models' faces while the new technology uses geometric methods, saving time and money, Yau says.
WASHINGTON, Sept. 13 (Xinhua) -- The U.S. Department of Agriculture (USDA) announced Tuesday it will begin testing next year for six more kinds of E.coli bacteria in raw ground beef and tenderized steaks in order to protect the safety of the American food supply.The U.S. currently tests for one strain of E.coli O157:H7 in beef. According to the USDA, from March 5 next year, if the E. coli serogroups O26, O103, O45, O111, O121 and O145 are found in raw ground beef or its precursors, those products will be prohibited from entering commerce.Like E.coli O157:H7, these serogroups can cause severe illness and even death, and young children and the elderly are at highest risk."The Obama Administration is committed to protecting our food supply and preventing illnesses before they happen," said Agriculture Secretary Tom Vilsack in a statement. "Today's announcement does exactly that by targeting and eliminating contaminated products from the market.""Too often, we are caught reacting to a problem instead of preventing it. This new policy will help stop problems before they start," he said.About one in six Americans becomes sick from a food borne illnesses each year, an epidemic that kills about 3,000 annually and hospitalizes 128,000, according to the U.S. Centers for Disease Control and Prevention.
