Software developed at Loughborough University in the United Kingdom reportedly could enable clinicians with no computer-aided design (CAD) experience to design and 3D-print custom wrist splints for people suffering from rheumatoid arthritis. The splints, produced at the university's additive manufacturing facilities, are described as more comfortable and attractive than conventional bulky splints that cause users to sweat, and could be less expensive, according to Dr Abby Paterson of the university's Design School.

Noncontact video extensometer enables tensile testing of plastics to ISO 527 standard

The Video Gauge noncontact extensometer from Imetrum (Bristol, UK) reportedly is the only device of its kind to achieve the exacting requirements of ISO 527-1: 2012 ASTM D638 equivalent. The system, which has undergone rigorous, independent testing, is capable of determining tensile modulus by measuring a change of gauge length to 1% accuracy of the relevant value. In tests, Imetrum was able to achieve between 0.2 and 0.3 µm for all gauge lengths using the same camera and lens combination. This exceeds by a factor of three the accuracy required by ISO 527 for a 50-mm gauge length.

Strange bedfellows? Ford and Heinz team up on tomato-based bioplastic for vehicles

While at first sight, cars and tomatoes may not have much in common, the collaboration between Ford and H.J. Heinz is less outlandish that would appear. Every year, Heinz uses more than two million tons of tomatoes to produce its best-selling product: Heinz Ketchup. And every year, the company ends up with a lot of tomato waste. Hence, researchers were looking for innovative ways to recycle and repurpose the peels, stems and seeds left over from making ketchup.

Some people famously started a business in their garage—you've seen the commercial. For Jennifer Davagian Ensign, founder and CEO of Cristcot Inc. (Concord, MA), it all began in her kitchen, but her invention has nothing to do with cuisine. Au contraire. Using a Smooth-On silicone moldmaking kit, sundry parts from local hardware stores, and her oven, Ensign taught herself the fundamentals of molding and, this month, brought to market—trigger warning, this may cause some of you to wince—Sephure, a disposable suppository applicator.

Light and strong are two qualities that standout from Pepsico's 28-ounce Gatorade bottle. In addition, using new roll-fed film label technology to shrink the labels onto the bottles eliminates adhesives and simulates direct printing. This form-fitting label eliminates water being trapped between the label and the bottle.
