An unusual solar flare observed by a NASA space observatory on Tuesday could cause some disruptions to satellite communications and power on Earth over the next day or so, officials said.

The potent blast from the Sun unleashed a firestorm of radiation on a level not witnessed since 2006, and will likely lead to moderate geomagnetic storm activity by Wednesday, according to the National Weather Service.

Cucumbers may be out of favor on earth, but a Japanese astronaut said Monday that he plans to harvest the vegetable on board the International Space Station.

Satoshi Furukawa is set to blast off early Wednesday for a half-year stint in orbit along with Russian cosmonaut Sergei Volkov and NASA astronaut Michael Fossum.

Apple chief executive Steve Jobs is taking a break from medical leave on Monday to preside over the opening of the company's annual conference for software developers.

And in a break from Apple's usual practice of shrouding its events in an air of mystery, the California gadget-maker this time revealed ahead of time what it plans to announce at the event in San Francisco.

Tropical 'Hotspots' May Get Too Warm to Climate change is on track to disrupt lifeline food crops across large swathes of Africa and Asia already mired in chronic poverty, according to an international study released Friday.

More than 350 million people face a "perfect storm" of conditions for potential food disaster, warns the report by scientists in the Consultative Group on International Agricultural Research (CGIAR).

The world's strongest winds race high in the sky, but that doesn't mean they're out of reach as a potentially potent energy source.

Flying, swooping and floating turbines are being developed to turn high-altitude winds into electricity.

From identifying Osama bin Laden to proving someone guilty of rape or murder, DNA analysis has become an essential scientific tool for police and criminal justice.

Unique genetic markers could play a crucial role in the trial of ex-IMF chief Dominique Strauss-Kahn, accused of sexually assaulting a hotel maid in New York.

Climate change is expected to alter the global industry in fruits and nuts dramatically as tree crops such as pistachios and cherries struggle in the rising temperatures, researchers said.

A study said that even if polluters took greater action to cut carbon emissions, the impact of climate change will likely be severe enough that the nearly $100 billion-a-year fruit and nut industry needs to reassess planning.

A 22-year-old Australian university student has solved a problem which has puzzled astrophysicists for decades, discovering part of the so-called "missing mass" of the universe during her summer break.

Undergraduate Amelia Fraser-McKelvie made the breakthrough during a holiday internship with a team at Monash University's School of Physics, locating the mystery material within vast structures called "filaments of galaxies".

The moon may have a lot more water than imagined, perhaps as much as on Earth in some parts, a study said Thursday, in a discovery that has cast doubt on long-held theories about how it was formed.

The moon was long thought to be a dusty, dry place until a few years ago when frozen water was discovered there for the first time.

The fourth of Europe's robot freighters, due to be launched to the International Space Station (ISS) in early 2013, has been named after Albert Einstein, the European Space Agency (ESA) said on Thursday.

The 20-ton Automated Transfer Vehicle (ATV) is one of Europe's main contributions to the multinational ISS project.
