Mars Express to relay first science data from Mars Curiosity

Posted: 06 Oct 2012 02:08 PM PDT

For 15 minutes, the NASA rover will transmit scientific data up to MEX, which will store it on board for a time. Then, two hours later, MEX will line up again, this time pointing its High Gain antenna toward Earth to downlink the precious information to the European Space Operations Centre (similar in role and function to NASA/JPL), Darmstadt, Germany.

Miniaturization of data storage devices? Origin of ultra-fast manipulation of domain walls discovered

Posted: 05 Oct 2012 09:37 AM PDT

Researchers have found a surprising effect that leads in ferromagnetic materials to a spatially varying magnetization manipulation on an ultrafast timescale. This effect could be the key to further miniaturization and performance increase of magnetic data storage devices.

Using less gas and oil to get where you’re going

A quick pit-stop at the gas station is enough to put a good dent in your wallet. New technology is set to lower the high cost of filling up your car, by enabling combustion engines to consume two to three percent less gas and signifi cantly less oil, while eliminating a step in engine production.

Could lightning strikes be used to break down rubble into useful components of cement and aggregate?

Posted: 05 Oct 2012 09:37 AM PDT

Every year several millions of tons of building rubble are produced. An efficient way of recycling concrete – the building material of the 20th and 21st century – does not yet exist. Researchers are working on new recycling methods, and with the aid of lightning bolts, they can break down the mixture of cement and aggregate into its components.
