NASA craft's pla... This artist rendition provided by NASA shows the Kepler space telescope. The spacecraft lost the second of four wheels that control the telescope’s orientation in space, NASA said Wednesday, May 15, 2013. If engineers can’t find a fix, the failure means the telescope won’t be able to look for planets outside our solar system anymore. (AP Photo/NASA)

Stem cells recov... This undated image made available by the Oregon Health & Science University in May 2013 shows developing cloned human embryos. Scientists have finally recovered stem cells from cloned human embryos, a longstanding goal that could lead to new treatments for such illnesses as Parkinson's disease and diabetes. In the Wednesday, May 15, 2013 edition of the journal Cell, scientists at the Oregon Health & Science University report harvesting stem cells from six embryos. Shoukhrat Mitalipov, who led the research, said the success came not from a single technical innovation, but from revising a series of steps in the process.

Report: Feds' wa... FILE - In this Oct. 30, 2012 file photo, a parking lot full of yellow cabs is flooded as a result of Superstorm Sandy in Hoboken, NJ. An internal review says federal weather forecasts for Superstorm Sandy were exceptionally accurately last fall. But the warnings themselves were confusing. The gigantic October storm lost tropical characteristics hours before landfall in New Jersey, so the National Oceanic and Atmospheric Administration dropped the hurricane warnings. Instead it shifted to flooding and high wind warnings. NOAA's self-assessment said that led to confusion by the public and the media, a complaint made by independent meteorologists.

Encroaching sea ... In this April 22, 2013 photo, fisherman Desmond Augustin stands on a breakwater of old tires and driftwood that local residents fashioned to try and protect their fishing village in Telegraph, Grenada. The people along this vulnerable stretch of eastern Grenada have been watching the sea eat away at their shoreline in recent decades, a result of destructive practices such as sand mining and a ferocious storm surge made worse by climate change, according to researchers with the U.S.-based Nature Conservancy, who have helped locals map the extent of coastal erosion.

Lava fountaining is visible near the summit, and steam and ash clouds rise from the northwest flank where a lava flow advances down the slope. (AP Photo/Alaskan Volcano Observatory, Rachel Kremer)

At remote outposts across Australia, scientists and spectators gathered to watch as the eclipse castes its approximately 200-kilometer-wide (120-mile-wide) shadow at dawn over Western Australia, before moving east through the Northern Territory and the top of Queensland state.(AP Photo/Rick Rycroft)

London Zoo seeks... This is an undated image made available Friday, May 10, 2013, by the Zoological Society of London (ZSL) of a male Mangarahara cichlid. Aquarists at the ZSL, London Zoo, are launching an urgent worldwide appeal to find a female mate for the last remaining males of a critically endangered fish species. The Mangarahara cichlid (Ptychochromis insolitus) is believed to be extinct in the wild, due to the introduction of dams drying up its habitat of the Mangarahara River in Madagascar, and two of the last known individuals are residing in ZSL London Zoo’s aquarium.

Solar plane land... The Solar Impulse plane takes off on a multi-city trip across the United States from Moffett Field NASA Ames Research Center in Mountain View, Calif., Friday, May 3, 2013. Solar Impulse, considered the world's most advanced solar-powered plane, will stop for seven to 10 days at major airports in each city, so the pilots can display and discuss the aircraft with reporters, students, engineers and aviation fans. It plans to reach New York's Kennedy Airport in early July — without using a drop of fuel, its creators said. (AP Photo/Tony Avelar)

FILE - This undated file image released by the British Health Protection Agency shows an electron microscope image of a coronavirus, part of a family of viruses that cause ailments including the common cold and SARS, which was first identified last year in the Middle East. The Ministry of Health in Saudi Arabia told world health officials that two health care workers became ill this month after being exposed to patients with the a deadly new respiratory virus related to SARS. One is critically ill. (AP Photo/Health Protection Agency, File)
East about to be... This photo provided by the University of Connecticut shows a cicada in Pipestem State Park in West Virginia on May 27, 2003. Any day now, cicadas with bulging red eyes will creep out of the ground after 17 years and overrun the East Coast with the awesome power of numbers. Big numbers. Billions. Maybe even a trillion. For a few buggy weeks, residents from North Carolina to Connecticut will be outnumbered by 600 to 1. Maybe more. And the invaders will be loud. A chorus of buzzing male cicadas can rival a jet engine. (AP Photo/University of Connecticut, Chirs Simon)
Experts: CO2 rec... In this Sunday, Dec. 2, 2012 photo, a flock of Geese fly past the smokestacks at the Jeffrey Energy Center coal power plant as the suns sets near Emmett, Kan. Worldwide levels of the chief greenhouse gas that causes global warming have hit a milestone, reaching an amount never before encountered by humans, federal scientists said Friday, May 10, 2013. Carbon dioxide was measured at 400 parts per million at the oldest monitoring station in Hawaii which sets the global benchmark. The last time the worldwide carbon level was probably that high was about 2 million years ago, said Pieter Tans of the National Oceanic and Atmospheric Administration. (AP Photo/Charlie Riedel)
