SAN FRANCISCO Andre-Pierre Gignac France Jersey , July 1 (Xinhua) -- Two researchers from Stanford University are exploring how corals that re-colonized Bikini Atoll after U.S. nuclear bomb tests 70 years ago have adapted to persistent radiation.

Humans and many other animals exposed to radiation often develop deoxyribonucleic acid (DNA) mutations in fast-dividing tissues that can result in cancer. Yet somehow, fast-growing coral in the ring of sand in the Pacific Ocean appear unharmed by the high levels of radiation found there.

Bikini Atoll experienced the historic fallout of 23 atomic bomb tests in the most northern of the Marshall Islands, located roughly halfway between Hawaii and Japan. The blasts Adil Rami France Jersey , detonated by the U.S. military in the years between 1946 and 1954, exposed corals and other species to persistent, high levels of radioactivity.

"The terrible history of Bikini Atoll is an ironic setting for research that might help people live longer Customized France Soccer Jerseys ," said Stephen Palumbi, Professor of Marine Science at Stanford, about his research efforts there. "By understanding how corals could have recolonized the radiation-filled bomb craters France Soccer Jerseys , maybe we can discover something new about keeping DNA intact."

Palumbi and biology graduate student Elora Lopez hope to better understand how the coral colonies withstand the high levels of radiation by sequencing their DNA and measuring rates and patterns of mutations.

Their work is featured in an episode of "Big Pacific," a Public Broadcasting Service Inc. (PBS) documentary series about species, natural phenomena and behaviors of the Pacific Ocean. A film crew captured Palumbi and Lopez diving in a hydrogen bomb crater Zinedine Zidane France Jersey , chasing radioactive crabs, sampling giant corals and witnessing something only reported once before, namely mutant sharks possibly missing their second dorsal fin.

"We should never forget what we did to Bikini Atoll and its people Yohan Cabaye France Jersey ," Lopez, as the project's leader, was quoted as saying in a news release from Stanford this week. "We should learn everything we can from it Steve Mandanda France Jersey , even things we would have never have thought of before."

Beyond coral, Lopez and Palumbi aim to understand how Bikini's larger ecosystem continues to thrive in terms of biodiversity and to expose hidden genetic damage. To that end, Lopez decided to look at platter-size crabs that eat coconuts filled with a radioactive isotope from groundwater. How do the crabs survive Samuel Umtiti France Jersey , grow and reproduce with such a burden of radioactivity? To answer this and other questions, the researchers will compare their species samples with those collected on Bikini by Smithsonian Institution researchers before the atomic tests.

BEIJING, Dec. 23 (Xinhua) -- Beijing prosecutors said Friday they will not prosecute five police personnel over a man's death in May.

The five, station deputy head Xing, a policeman and three other security personnel, had committed improper acts in their work, which led to the death of a man surnamed Lei and they did not promptly call for help when Lei appeared ill, according to Fengtai District People's Procuratorate.

On the evening of May 7, when Lei left a massage house in Changping District after engaging in commercial sex, the five attempted to take him in for questioning.

Lei struggled but was put into a car. When Lei attempted to jump out of the car he was handcuffed. He then appeared to be paralyzed and stopped shouting. He was declared dead at hospital the same night, having choked on his own vomit.

The police action amounted to negligence, but they were working in accordance with a special campaign, under the instructions of their superiors and Lei had resisted arrest.

Criminal action was minor and the five pleaded guilty, so the procuratorate decided not to prosecute them.

The procuratorate advised that the five be seriously dealt with by discipline organs.



BERLIN, April 17 (Xinhua) -- Dortmund moved 3-0 past Hamburg by courtesy of Adrian Ramos' brace whereas Cologne came from behind to snatch a 3-2 win at Mainz to close the 30th round in the German Bundesliga on Sunday.

Runner-up Dortmund recovered from their dramatic UEFA Europa League exit at Liverpool on Thursday, by beating Hamburg 3-0 thanks to their clinical chance conversion on home soil.

However, it was the visitors from the North who created the first chances of the encounter. Ivo Ilicevic's diving header missed the target narrowly in the 16th minute before Dortmund's defender Mats Hummels last-grasp tackle hindered Sven Schipplock to beat onrushing custodian Roman Buerki 20 minutes later.

The hosts cut a better figure in front of Hamburg's goal area as US international Christian Pulisic unleashed a right-footed low effort into the near post corner to break the deadlock with 38 minutes played.

Hamburg wobbled and suffered another goal against as Adrian Ramos curled home Nuri Sahin's build-up work from 12 meters into the far post corner with one minute remaining in the first half.

Things went from bad to worse for Hamburg after goalkeeper Rene Adler brought down Shinji Kagawa outside the box to see a straight red card with seven minutes into the second half.

Dortmund, now in superior numbers, controlled the proceedings and tripled the lead as Ramos wrapped up his brace with four minutes from time, rounding off 22nd victory of the season.

With the result, second-placed Dortmund sit seven points adrift of front runners Bayern Munich with four games to spare meanwhile Hamburg slumped to the 12th place with a three-point advantage to a relegation play-off spot.

Elsewhere, Mainz squandered a two-goal lead allowing Cologne to score three second-half goals to turn the tides. Jhon Cordoba and Leon Balogun established the 2-0 lead within 46 minutes before Cologne bounced back through the goals from Marcel Risse, Milos Jojic and Anthony Modeste.<. Cheap Jerseys Free Shipping   Cheap Jerseys Wholesale   Wholesale Jerseys From China   Wholesale Jerseys Free Shipping   Wholesale NBA Hoodie   Wholesale MLB T-Shirts   Wholesale Adidas NHL T-Shirts   Wholesale Football T-Shirts   Wholesale MLB T-Shirts   Cheap Nike NBA Hats
