To make a social robot, key is satisfying the human mind Posted: 03 Feb 2012 07:11 AM PST Understanding the human mind is the key to social robotics, and researchers describe what we can expect from this field in the future.

Classic portrait of a barred spiral galaxy Posted: 03 Feb 2012 06:24 AM PST The NASA/ESA Hubble Space Telescope has taken a picture of the barred spiral galaxy NGC 1073, which is found in the constellation of Cetus (The Sea Monster). Our own galaxy, the Milky Way, is a similar barred spiral, and the study of galaxies such as NGC 1073 helps astronomers learn more about our celestial home.

Surface of Mars an unlikely place for life after 600-million-year drought, say scientists Posted: 03 Feb 2012 06:20 AM PST Mars may have been arid for more than 600 million years, making it too hostile for any life to survive on the planet's surface, according to researchers who have been carrying out the painstaking task of analyzing individual particles of Martian soil.

Graphene electronics moves into a third dimension Posted: 02 Feb 2012 12:10 PM PST Wonder material graphene has been touted as the next silicon, with one major problem – it is too conductive to be used in computer chips. Now scientists have given its prospects a new lifeline. Scientists have now literally opened a third dimension in graphene research. Their research shows a transistor that may prove the missing link for graphene to become the next silicon.

Biosolar breakthrough promises cheap, easy green electricity Posted: 02 Feb 2012 06:22 AM PST Scientists have developed a system that taps into photosynthetic processes to produce efficient and inexpensive energy.
