First observation of atomic diffusion inside bulk material Posted: 13 Oct 2014 08:23 AM PDT Researchers have obtained the first direct observations of atomic diffusion inside a bulk material. The research could be used to give unprecedented insight into the lifespan and properties of new materials.

Bio-inspired 'nano-cocoons' offer targeted drug delivery against cancer cells Posted: 13 Oct 2014 07:39 AM PDT Biomedical engineering researchers have developed a drug delivery system consisting of nanoscale "cocoons" made of DNA that target cancer cells and trick the cells into absorbing the cocoon before unleashing anticancer drugs.

Tailored flexible illusion coatings hide objects from detection Posted: 13 Oct 2014 06:06 AM PDT Developing the cloak of invisibility would be wonderful, but sometimes simply making an object appear to be something else will do the trick, according to electrical engineers.

'Smart' lithium-ion battery warns of fire hazard Posted: 13 Oct 2014 06:05 AM PDT Scientists have developed a 'smart' lithium-ion battery that gives ample warning before it overheats and bursts into flames. The new technology is designed for conventional lithium-ion batteries now used in billions of cellphones, laptops and other electronic devices, as well as a growing number of cars and airplanes.

Lead-free glass decor Posted: 13 Oct 2014 06:02 AM PDT Whether on baby bottles, beer mugs or perfume bottles, imprints on glass consist mainly of lead oxide. Researchers have developed printing inks for glass that do not contain any toxic elements.

Antibiotic resistance: Bacterial defense policies Posted: 13 Oct 2014 06:02 AM PDT High-resolution cryo-electron microscopy has now revealed in unprecedented detail the structural changes in the bacterial ribosome which results in resistance to the antibiotic erythromycin.

Nanoparticles can act like liquid on the outside, crystal on the inside Posted: 12 Oct 2014 10:49 AM PDT A surprising phenomenon has been found in metal nanoparticles: They appear, from the outside, to be liquid droplets, wobbling and readily changing shape, while their interiors retain a perfectly stable crystal configuration.

New records set for silicon quantum computing Posted: 12 Oct 2014 10:48 AM PDT Two research teams working in the same laboratories have found distinct solutions to a critical challenge that has held back the realization of super powerful quantum computers. The teams created two types of quantum bits, or "qubits" -- the building blocks for quantum computers -- that each process quantum data with an accuracy above 99%.

A novel platform for future spintronic technologies Posted: 12 Oct 2014 10:48 AM PDT Spintronics is a new field of electronics, using electron spin rather than charge. Scientists have now shown that a conventional electrical insulator can be used as an optimal spintronic device.

Demand high for engineers in Midwest Posted: 10 Oct 2014 10:43 AM PDT Engineering students preparing to take their sheepskin and depart into the world of change orders and service requests are finding no shortage of companies wanting to take their resumes.
