South Korea hopes to launch a satellite into space on Friday in its third attempt to join an elite club that includes Asian powers China, Japan and India.

After two previous failures in 2009 and 2010, the 140-tonne Korea Space Launch Vehicle (KSLV-I) will, weather permitting, blast off from the Naro Space Center on the south coast.

It could be the muffled sound of singing in the shower or that sing-songy indecipherable voice from the Muppets' Swedish Chef.

Surprisingly, scientists said the audio they captured was a whale imitating people. In fact, the whale song sounded so eerily human that divers initially thought it was a human voice.

Scientists on Tuesday said the sentencing of six Italian seismologists for underestimating the risk of a 2009 earthquake was a blow to scientific freedom, and some likened it to the persecution of Galileo.

From research into new drugs to identifying rogue asteroids that could strike Earth or even weather forecasting, all branches of science that advise the public about risk are at threat, they said.

A Russian spacecraft surged into clear skies over the Central Asian steppe Tuesday, carrying a three-man crew on their way to the International Space Station.

The engines of the Soyuz TMA-06M sent a powerful roar across the tinder-dry countryside of southern Kazakhstan as scheduled in the afternoon to deliver NASA astronaut Kevin Ford and Russians Oleg Novitsky and Yevgeny Tarelkin to the orbiting laboratory.

Global environmental watchdog Greenpeace launched a new report Monday warning the European Union against authorizing herbicide-tolerant genetically engineered (HTGE) crops, saying they would lead to herbicide-resistant super-weeds.

"When herbicide-tolerant crops are relied on heavily, they trigger the spread and emergence of resistant weeds, which has now happened throughout the United States," said Oregon-based agricultural economist Charles Benbrook, who was commissioned by Greenpeace to study the issue.

An eel undulating through coastal waters, powered by batteries and checking for mines. A jellyfish is actually a surveillance robot, powered by the atoms around it. Fins pick up intelligence while propelling a robot bluegill sunfish.

The Office of Naval Research is supporting baby steps toward making those visions of the future a reality. For instance, the jellyfish work in Texas and Virginia is focused on how the creatures move in water, and how to mimic or even surpass their abilities. The robojellyfish is currently tethered to hydrogen and oxygen tanks, and ONR project manager Robert Brizzolara said he doesn't plan to try making it move autonomously yet.

U.S. scientists on Tuesday joined global colleagues in expressing outrage at an Italian court's sentencing of six seismologists to jail for underestimating the risks of a 2009 earthquake.

The Union of Concerned Scientists denounced the watershed ruling -- in which the six Italian scientists and a government official were sentenced to six years in jail for multiple manslaughter -- as "absurd and dangerous."

A U.S. astronaut departing this week for the International Space Station said Monday that the bulk of the scientific benefits from the orbiting laboratory will be seen over the coming decade, amid questions on whether the estimated $100 billion spent in last 12 years is worth the effort.

"The first ten years were really intensive in the construction side of it, bringing all the pieces together and really getting the science enabled," said NASA astronaut Kevin Ford, who will blast off on a Soyuz craft from the Russian-leased Baikonur spacer center in Kazakhstan on Tuesday together with Russian colleagues Oleg Novitsky and Yevgeny Tarelkin.

Massive extraction of groundwater helped unleash an earthquake in southeastern Spain last year that killed nine people, injured at least 100 and left thousands homeless, geologists said on Sunday.

The finding adds a powerful piece of evidence to theories that some earthquakes are human-induced, they said.

Chronic exposure to pesticides has a bigger knock-on effect on bees than conventional probes suggest, according to a new study on Sunday touching on the mysterious collapse of bee colonies.

Biologists at the University of London carried out an exceptional field study into bumblebees exposed to two commonly used agricultural insecticides.
