- 3D printing adds a fourth dimension
So-called 4D printing takes 3D printing a step further, enabling individual chunks of material to assemble themselves intelligently into any form desired. The new technology from Skylar Tibbits activates individual strands of material that in turn guide themselves into the prescribed shapes. The process also has the advantage of enabling the objects to be self-adapting after their creation. Wired.co.uk (U.K.)

- Printed car may point way to small-batch production
Small-batch automakers may be the future with 3D printing as explored by Jim Kor with his Urbee 2. The extremely lightweight urban vehicle is made possible by 3D printing, which alone has the capability of producing parts with sufficient strength and the weight savings required for fuel economy.

- New cooling system immerses servers in liquid
A non-conductive liquid 1,000 times more efficient than air at bleeding away heat is the key to a new type of server being tested at the U.K.'s University of Leeds. The server, developed with Iceotope, also employs a pump at the base of the cabinet to recirculate the liquid, using water as a secondary coolant. Bit-Tech.net

- Aviation explores new ways of saving fuel and planet
 To reduce fuel bills and address concerns over global warming, the airline industry is taking another look at the old technology of propeller-driven planes. Rolls-Royce's open-rotor design is touted for its potential to reduce carbon dioxide emissions by 10,000 tons annually per plane. And the Massachusetts Institute of Technology says it has a prototype of an entire aircraft that can reduce fuel consumption by 40%. CleanTechnica

- What's next in automotive engineering?
Engine efficiency, fuel economy, improved transmissions and reduced vehicle weight are just some of the current trends in automotive engineering, writes Mark Crawford. However, battery management systems, smaller internal combustion engines and the creation of advanced combustion modes are emerging as focal points, Crawford writes. ASME.org

- Israeli system saves shower water that would otherwise be wasted
Water lost while a faucet runs as the user waits for the proper bathing temperature can now be recovered with a system designed for use in parched Israel. The system, developed by students at Ariel University, stores water until hot water reaches the shower head and only then directs the flow outward. The saved water is then pumped out of the system's storage tank for use elsewhere. TriplePundit.com

- MEMS, tiny devices, increasingly shape our world
Microscale devices that measure between 1 micrometer and 1 millimeter open up a world of possibilities, ranging from touchscreens to motion detection for gaming devices and tablet computers and variable heart pacemakers. But the devices, known as MEMS or MicroElectroMechanical Systems, have proliferated only since it became possible to produce them using modified semiconductor fabricating technologies.

- Study shows more than half use nanotechnology
More than half of the respondents to an ASME Research Committee on Nanomanufacturing Technology survey said they are currently enhancing existing products or processes by incorporating nanotechnology. The results of the survey will be used to organize an industrial needs assessment workshop. Learn more.
