New fuel cell keeps going after the hydrogen runs out

Posted: 29 Jun 2012 06:19 PM PDT

Materials scientists have demonstrated a solid-oxide fuel cell that converts hydrogen into electricity but can also store electrochemical energy like a battery. This fuel cell can continue to produce power for a short time after its fuel has run out.

Clothing the body electric: Cotton T-shirt fabric can store electricity, maybe keep your cell phone charged

Posted: 29 Jun 2012 06:15 PM PDT

The fabric in a cotton T-shirt was converted into a material that can store electricity. A flexible source of electrical power made from this kind of material might one day be able to charge your cell phone, or any number of other mobile electronic devices.

Making the shortest light bursts leads to better understanding of nature

Posted: 29 Jun 2012 06:15 PM PDT

An attosecond is a ridiculously brief sliver of time – a scant billionth of a billionth of a second. This may seem too short to have any practical applications, but at the atomic level, where electrons zip and jump about, these vanishingly short timescales are crucial to a deeper understanding of science.

Stealthy microscopy method visualizes E. coli sub-cellular structure in 3-D

Posted: 29 Jun 2012 11:26 AM PDT

A sub-cellular world has been opened up for scientists to study E. coli and other tissues in new ways, thanks to a microscopy method that stealthily provides 3-D, high-quality images of the internal structure of cells without disturbing the specimen.

Scientists help create an extra second of summer: Leap second to be added on July 1, 2012

Scientists will be adding a leap second at 00:59 BST on July 1 to its atomic clocks, to ensure UK time remains synchronized with international time.

How to bend it like Beckham: Physics students calculate perfect soccer ball kicking formula

Posted: 29 Jun 2012 09:03 AM PDT

Now that David Beckham won't be appearing at the London 2012 Olympics, other members of Team GB wanting to brush up on their free-kicks can rest easy. A physics students has figured out the optimum way of kicking a soccer ball in order to make it bend into the goal. The ex-England captain's curling free-kicks became legendary, and even inspired the title of the 2002 film Bend It Like Beckham.

Multiple mergers generate ultraluminous infrared galaxy

Posted: 29 Jun 2012 09:03 AM PDT

Ultraluminous infrared galaxies are the most luminous class of galaxies in the relatively near or local Universe. Most of their energy output is in the infrared range, suggesting that they contain a large amount of dust, an indication of immense star formation.

Colorful light at the end of the tunnel for radiation detection

Posted: 29 Jun 2012 08:56 AM PDT

Nanomaterials researchers have developed a new technique for radiation detection that could make radiation detection in cargo and baggage more effective and less costly for homeland security inspectors.

First heralded single photon source made from silicon

Posted: 28 Jun 2012 11:57 AM PDT

In an important step towards more practical quantum information processing, researchers have built the first heralded single photon source made from silicon. This source complements two other recently developed silicon-based technologies needed to build a quantum optical circuit or a secure quantum communication system.
