Researchers call for specialty metals recycling Posted: 24 Sep 2012 02:52 PM PDT An international policy is needed for recycling scarce specialty metals that are critical in the production of consumer goods, according to researchers.

Exposing cancer's lethal couriers Posted: 24 Sep 2012 12:25 PM PDT New nanotechnology detects metastases in mouse models of breast cancer before they've grown into new tissues. Images of the precise location and extent of metastases could be used to guide surgery or ablation, or the same technology used to find the cancer could be used to deliver cancer-killing drugs.

A clock that will last forever: Proposal to build first space-time crystal Posted: 24 Sep 2012 11:47 AM PDT Imagine a clock that will keep perfect time forever or a device that opens new dimensions into the study of quantum phenomena such as emergence and entanglement. Researchers have proposed a space-time crystal based on an electric-field ion trap and the Coulomb repulsion of particles that carry the same electrical charge.

Wearable sensor system automatic maps building while wearer is moving Posted: 24 Sep 2012 11:47 AM PDT Researchers have built a wearable sensor system that automatically creates a digital map of the environment through which the wearer is moving.

Scientists shed light on riddle of sun's explosive events Posted: 24 Sep 2012 11:40 AM PDT Four decades of active research and debate by the solar physics community have failed to bring consensus on what drives the sun's powerful coronal mass ejections that can have profound "space weather" effects on Earth-based power grids and satellites in near-Earth geospace.

NASA's Chandra shows Milky Way is surrounded by halo of hot gas Posted: 24 Sep 2012 09:30 AM PDT Astronomers have used NASA's Chandra X-ray Observatory to find evidence our Milky Way Galaxy is embedded in an enormous halo of hot gas that extends for hundreds of thousands of light years. The estimated mass of the halo is comparable to the mass of all the stars in the galaxy.

Cheaper way to produce nickel ferrite ceramic thin films Posted: 24 Sep 2012 08:18 AM PDT Researchers have demonstrated a less-expensive way to create textured nickel ferrite (NFO) ceramic thin films, which can easily be scaled up to address manufacturing needs. NFO is a magnetic material that holds promise for microwave technologies and next-generation memory devices.

Glass half full: Double-strength glass may be within reach Posted: 24 Sep 2012 08:18 AM PDT Researchers apply a new theory that describes the transition of glass from a liquid to a solid to its intrinsic strength, and they find it may be possible to make glass stronger.

Fueling the fleet, U.S. Navy looks to the seas Posted: 24 Sep 2012 08:18 AM PDT Scientists at the U.S. Naval Research Laboratory are developing a process to extract carbon dioxide and produce hydrogen gas from seawater, subsequently converting the gases into jet fuel by a gas-to-liquids process.

Hubble catches glowing gas and dark dust in a side-on spiral Posted: 24 Sep 2012 06:39 AM PDT The NASA/ESA Hubble Space Telescope has produced a sharp image of NGC 4634, a spiral galaxy seen exactly side-on. Its disk is slightly warped by ongoing interactions with a nearby galaxy, and it is crisscrossed by clearly defined dust lanes and bright nebulae.

Using artificial intelligence to chart the universe Posted: 24 Sep 2012 05:03 AM PDT Astronomers have developed an artificial intelligence algorithm to help them chart and explain the structure and dynamics of the universe around us with unprecedented accuracy. Scientists routinely use large telescopes to scan the sky, mapping the coordinates and estimating the distances of hundreds of thousands of galaxies and so enabling them to create a map of the large-scale structure of the Universe.
