Scientists to Jupiter's moon Io: Your volcanoes are in the wrong place

Posted: 04 Apr 2013 02:02 PM PDT

Jupiter's moon Io is the most volcanically active world in the Solar System, with hundreds of volcanoes, some erupting lava fountains up to 250 miles high. However, concentrations of volcanic activity are significantly displaced from where they are expected to be based on models that predict how the moon's interior is heated, according to researchers.

Listening to the Big Bang -- in high fidelity

A custom-built programmable 3-D printer can create materials with several of the properties of living tissues, scientists have demonstrated.

Chemistry: Elusive mechanism of widely used click reaction revealed

Posted: 04 Apr 2013 11:24 AM PDT

Scientists have illuminated the mechanism at the heart of one of the most useful processes in modern chemistry. A reaction that is robust and easy to perform, it is widely employed to synthesize new pharmaceuticals, biological probes, new materials and other products.

Rocket powered by nuclear fusion could send humans to Mars

Posted: 04 Apr 2013 10:52 AM PDT

Scientists are building components of a fusion-powered rocket aimed to clear many of the hurdles that block deep space travel, including long times in transit, exorbitant costs and health risks.

Bronze warship ram reveals secrets

Posted: 04 Apr 2013 09:24 AM PDT

The Belgammel Ram, a 20kg bronze battering ram artifact dating to between 100BC and 100AD has been extensively tested and analyzed to ascertain how it would have been made in ancient times. The development of new techniques and analyses will assist future research on similar artifacts.

New camera system creates high-resolution 3-D images from up to a kilometer away

Posted: 04 Apr 2013 09:22 AM PDT

A new camera system provides high-resolution, 3-D information about objects that are typically difficult to image, from up to a kilometer away. The photo-counting depth imaging system is likely to be used for scanning static, human-made targets from afar, such as vehicles. It could also determine their speed and direction, or be used for remote examination of vegetation and the movement of rock faces, to assess potential hazards from as far as 10 km away.

Hubble breaks record in search for farthest supernova

Posted: 04 Apr 2013 07:45 AM PDT

NASA's Hubble Space Telescope has found the farthest supernova so far of the type used to measure cosmic distances. Supernova UDS10Wil, nicknamed SN Wilson after American President Woodrow Wilson, exploded more than 10 billion years ago.

Don't call it vaporware: Scientists use cloud of atoms as optical memory device

Posted: 04 Apr 2013 06:28 AM PDT

Talk about storing data in the cloud. Scientists have taken this to a whole new level by demonstrating that they can store visual images within quite an ethereal memory device -- a thin vapor of rubidium atoms. The effort may prove helpful in creating memory for quantum computers.
