Hubble observes glowing, fiery shells of gas Posted: 01 Mar 2013 01:10 PM PST A new image from the Hubble Space Telescope may look like something from "The Lord of the Rings," but this fiery swirl is actually a planetary nebula known as ESO 456-67. Set against a backdrop of bright stars, the rust-colored object lies in the constellation of Sagittarius (The Archer), in the southern sky.

3-D printing using old milk jugs Posted: 01 Mar 2013 12:36 PM PST 3-D printing lets anyone make almost anything with a simple machine and a roll of plastic filament. Now researchers have found a way to drive costs down even further by recycling empty milk jugs into filament. The process reduces landfill waste, saves on energy compared with traditional recycling, and makes 3-D printing and even better deal.

US may face inevitable nuclear power exit Posted: 01 Mar 2013 09:29 AM PST In the third and final issue in a series focused on nuclear exits, the Bulletin of the Atomic Scientists, published by SAGE, turns its attention to the United States and looks at whether the country's business-as-usual approach may yet lead to a nuclear phase-out for economic reasons.

Turbulence in a crystal Posted: 01 Mar 2013 02:16 AM PST When a crystal is hit by an intense ultrashort light pulse, its atomic structure is set in motion. Scientists can now observe how the configuration of electrons and atoms in titanium dioxide, a semiconductor, changes under the impact of an ultraviolet laser pulse, confirming that even subtle changes in the electron distribution caused by the excitation can have a considerable impact on the whole crystal structure.
