PARIS, June 12, 2013 (Agence France Presse) - More pest species are becoming resistant to the most popular type of genetically-modified, insect-repellent crops, but not in areas where farmers follow expert advice, a study said on Monday.

New York Mayor Michael Bloomberg on Tuesday unveiled a $19.5 billion plan to boost the city's defenses against climate change, seven months after superstorm Sandy devastated the U.S. East Coast.

The blueprint features structures like a series of six-meter-high (20-foot) waterfront walls and dikes to prevent flooding of the kind that idled the city for days in the late October 2012 storm.

By the 2050s, more than 800,000 New York City residents could be living in a flood zone that would cover a quarter of the city's land and New Yorkers could sweat out as many 90-degree (32-Celsiu) days as is now normal for Birmingham, Alabama, as effects of global warming take hold, a scientists' group convened by the city says.

With local waters higher than they are today, 8 percent of the city's coastline could see flooding just from high tides, the group estimates. And while the average day could significantly hotter, a once-in-a-century storm would likely spur a surge higher than Superstorm Sandy, which sent a record 14-foot (4.3-meter) storm tide gushing into lower Manhattan.

China was to launch its longest-ever space mission on Tuesday, with its second woman astronaut among the crew, as it steps up its ambitious space program, a symbol of the country's growing power.

The Shenzhou-10 -- the name means "Divine Vessel" -- was due to lift off at 0938 GMT from the Jiuquan launch center in the Gobi desert.

China is to send its second woman astronaut into orbit on its longest mission yet, space officials said Monday, as the country works towards building a space station.

The Shenzhou-10 -- the name means "Divine Vessel" -- will be launched on a Long March rocket at 0938 GMT Tuesday, Wu Ping, spokeswoman for China's manned space program, told a news conference.

Rising carbon emissions will place parts of India, China, Southeast Asia, East Africa and the northern Andes at a higher risk of extreme floods, a study published on Sunday says.

Global warming will boost the frequency at which exceptional floods occur in these regions, while eastern Europe, parts of Scandinavia, Chile and Argentina will have fewer such events, it suggests.

In a tropical Chinese rainforest, seven savannah-dwelling African rhinos are said to be awaiting release into the wild, raising fears for their welfare in a country with a booming rhino horn trade.

The animals arrived with a blaze of publicity in March at the vast Pu'er National Forest Park in the humid hills of Yunnan province in southwest China, with television images showing cranes lowering the huge beasts into paddocks.

Scientists on Friday called NASA's Opportunity rover gimpy and arthritic, but hailed its new discoveries about early water on Mars made almost 10 years after it was launched toward the Red Planet.

The unmanned solar-powered vehicle has just analyzed what may be its oldest rock ever, known as Esperance 6. It contains evidence that potentially life-supporting water once flowed in abundance, leaving clay minerals behind.

Russia's Valentina Tereshkova, the first woman to go to space, said on Friday she was ready to score another coup and fly to Mars, even if it would be just a one-way trip.

"Mars is my favorite planet," the 76-year old told a news conference in Zvyozdny Gorodok (Star City) outside Moscow, home to a cosmonaut training centre.

A "dust trap" surrounding a young star could help explain how planets are formed, astronomers with Chile's ALMA space observatory said on Thursday.

The findings provide insight into how dust particles in the disk around a young star grow in size so that, over time, they form comets and planets.
