Meteorites reveal another way to make life's components

Posted: 09 Mar 2012 07:48 AM PST

Creating some of life's building blocks in space may be a bit like making a sandwich -- you can make them cold or hot, according to new NASA research. This evidence that there is more than one way to make crucial components of life increases the likelihood that life emerged elsewhere in the Universe, according to the research team, and gives support to the theory that a "kit" of ready-made parts created in space and delivered to Earth by impacts from meteorites and comets assisted the origin of life.

A cheap and fully optical solution for ultra-fast internet

Posted: 09 Mar 2012 07:41 AM PST

Blisteringly fast Internet speeds, more robust connections and a big increase in network capacity at little extra cost, even in rural areas? It's the sort of fantasy that keeps telecommunication company executives and bandwidth-hungry Internet users awake at night... until now. Groundbreaking fibre-optic technology promises all those things and more.

Mapping the Moho with GOCE

Posted: 09 Mar 2012 07:38 AM PST

The first global high-resolution map of the boundary between Earth's crust and mantle – the Moho – has been produced based on data from ESA's GOCE gravity satellite. Understanding the Moho will offer new clues into the dynamics of Earth's interior. Earth's crust is the outermost solid shell of our planet. Even though it makes up less than 1% of the volume of the planet, the crust is exceptionally important not just because we live on it, but because is the place where all our geological resources like natural gas, oil and minerals come from.

Strong Grip: Unexpected interaction between organic semiconductors

Posted: 09 Mar 2012 07:38 AM PST

Physicists have discovered an unexpectedly strong bond between organic layers. Such structures are still puzzling scientists throughout the world. These structures form the basis for novel electronic components made from organic semiconductors that are now increasingly used in smart phones and television sets.

Tracking pedestrians indoors using their smart phones

Posted: 09 Mar 2012 07:38 AM PST

The next generation of smart phone could combine the data from its gyroscopes with a built-in compass to allow you to track your movements when indoors even without GPS. Such a system could be useful for shopping mall managers, factory bosses for worker safety and security and office workers hoping to manage the flow of people through buildings. It could also be used to enable location based services and to help users navigate to specific meeting points or shops.

Catalysts for less: Slashing costs of metal alloys needed to jump-start crucial chemical processes

Posted: 08 Mar 2012 11:31 AM PST

Scientists have discovered that individual atoms can catalyze industrially important chemical reactions such as the hydrogenation of acetylene, offering potentially significant economic and environmental benefits.
