Inspired by a toy, the 'buckliball' -- a collapsible structure fabricated from a single piece of material -- represents a new class of 3-D, origami-like structures.
Strains of E. coli bacteria were engineered to digest switchgrass biomass and synthesize its sugars into gasoline, diesel and jet fuel. The switchgrass, which is among the most highly touted of the potential feedstocks for advanced biofuels, was pre-treated with ionic liquid, a key to the success of this study.
By depositing atoms on one side of a grid of the "miracle material" graphene, researchers ave engineered piezoelectricity into a nanoscale material for the first time. The implications could yield dramatic degree of control in nanotechnology.
Researchers have developed a new technique that allows graphics processing units (GPUs) and central processing units (CPUs) on a single chip to collaborate – boosting processor performance by an average of more than 20 percent.

Researchers in California report that they have significantly enhanced polymer solar cells' performance by building a device with a new "tandem" structure that combines multiple cells with different absorption bands. The device had a certified power-conversion efficiency of 8.62 percent and set a world record in July 2011.
Engineers have developed a one-step, low-cost method to fabricate a polymer that is rainbow-colored, reflecting many different wavelengths of light when viewed from a single perspective. The colors won't fade with time because they are produced by surface geometry, and not pigment -- the same principle that gives color to the wings of butterflies and feather of peacocks.
It sounded like an odd but harmless experiment. 
Last October British scientists planned to send a balloon more than half a mile high to spray water into the air. Yet a few days before the test, it was delayed amid major backlash from environmental groups.
(University of California - Los Angeles) Imagine being able to use electricity to power your car and it's not an electric vehicle. Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have for the first time demonstrated a method for converting carbon dioxide into liquid fuel isobutanol using electricity.
We introduce a class of continuum shell structures, the Buckliball, which undergoes a structural transformation induced by buckling under pressure loading. The geometry of the Buckliball comprises a spherical shell patterned with a regular array of circular voids.
