Engineering Newswire 57: DARPA's experimental program sends drones to space

September 30, 2013 9:23 am | by Eric Sorensen, Coordinator of Multimedia Development | Videos | Comments

Today on Engineering Newswire, we're microwaving rubble, expanding access to space, designing elastic OLEDs, and flying tinker toys to space. This episode features: DARPA has come up with a new experimental space program -- XS-1 -- which aims to develop a fully reusable, unmanned vehicle that would provide aircraft-like access to space.


Photos of the Day: NASA preparing to launch 3-D printer into space

September 30, 2013 9:12 am | by MARTHA MENDOZA, AP National Writer | News | Comments

NASA is preparing to launch a 3-D printer into space next year, a toaster-sized game changer that greatly reduces the need for astronauts to load up with every tool, spare part or supply they might ever need. The printers would serve as a flying factory of infinite designs, creating objects by extruding layer upon layer of plastic from long strands coiled around large spools.

Hear where you are: How sound not only informs, but places us

September 27, 2013 4:44 pm | by EurekAlert! | News | Comments

School children learn that humans have five senses, all of which are used to help make decisions. Sound is typically thought of as a means of gathering information. But in a new book – Hear Where We Are: Sound, Ecology, and Sense of Place – author Michael Stocker, Executive Director of Ocean Conservation Research, proposes that sound serves a far deeper function.

Scientists find a martian igneous rock that is surprisingly Earth-like

September 27, 2013 4:34 pm | by EurekAlert! | News | Comments

During the nearly 14 months that it has spent on the red planet, Curiosity, the Mars Science Laboratory (MSL) rover, has scooped soil, drilled rocks, and analyzed samples by exposing them to laser beams, X-rays, and alpha particles using the most sophisticated suite of scientific instruments ever deployed on another planet.


Bright, laser-based lighting devices

September 27, 2013 4:32 pm | by EurekAlert! | News | Comments

As a modern culture, we crave artificial white lights -- the brighter the better, and ideally using less energy than ever before. To meet the ever-escalating demand for more lighting in more places and to improve the bulbs used in sports stadiums, car headlights and street lamps, scientists are scrambling to create better light-emitting diodes....


3-D models of electrical streamers

September 27, 2013 4:27 pm | by EurekAlert! | News | Comments

Streamers may be great for decorating a child's party, but in dielectrics, they are the primary origin of electric breakdown. They can cause catastrophic damage to electrical equipment, harm the surrounding environment, and lead to large-scale power outages. Understanding streamers and the mechanisms behind their initiation, acceleration and branching is necessary....


Researchers demonstrate 'accelerator on a chip'

September 27, 2013 4:13 pm | by EurekAlert! | News | Comments

In an advance that could dramatically shrink particle accelerators for science and medicine, researchers used a laser to accelerate electrons at a rate 10 times higher than conventional technology in a nanostructured glass chip smaller than a grain of rice.
