| Shot away from its companion, giant star makes waves: Spitzer captures infrared portrait Posted: 18 Dec 2012 12:33 PM PST Like a ship plowing through still waters, the giant star Zeta Ophiuchi is speeding through space, making waves in the dust ahead. NASA's Spitzer Space Telescope has captured a dramatic, infrared portrait of these glowing waves, also known as a bow shock.  |
| From super to ultra: Just how big can black holes get? Posted: 18 Dec 2012 11:30 AM PST Some of the biggest black holes in the Universe may actually be even bigger than previously thought, according to a study using data from NASA's Chandra X-ray Observatory.  |
| Liquid metal used to create wires that stretch eight times their original length Posted: 18 Dec 2012 09:14 AM PST Researchers have created conductive wires that can be stretched up to eight times their original length while still functioning. The wires can be used for everything from headphones to phone chargers, and hold potential for use in electronic textiles.  |
| Posted: 18 Dec 2012 05:17 AM PST Scientists have used synchrotron-based imaging techniques to identify previously unseen anatomy preserved in fossils. Their work on a 50-million-year-old lizard skin identified the presence of teeth (invisible to visible light), demonstrating for the first time that this fossil animal was more than just a skin moult. This was only possible using some of the brightest light in the universe, X-rays generated by a synchrotron.  |
| Bullying by childhood peers leaves a trace that can change the expression of a gene linked to mood Posted: 18 Dec 2012 05:16 AM PST A recent study suggests that bullying by peers changes the structure surrounding a gene involved in regulating mood, making victims more vulnerable to mental health problems as they age.  |
