Magnetic 3D-printed structures crawl, roll, and jump

Engineers have created soft, 3D-printed structures whose movements can be controlled with a wave of a magnet, much like marionettes without the strings. The menagerie of structures that can be magnetically manipulated includes a smooth ring that wrinkles up, a long tube that squeezes shut, a sheet that folds itself, and a spider-like 'grabber' that can crawl, roll, jump, and snap together fast enough to catch a passing ball.


Attacking bacteria with shark skin-inspired surfaces

Sharks are often the subject of TV specials or news stories focusing on their attacks on humans. But scientists are finding that sharks could inspire a new type of surface that would attack bacteria, helping humans instead of hurting them. Researchers have designed a coating that is infused with antimicrobial agents and has the patterned diamond-like texture of shark skin.


E- textiles control home appliances with the swipe of a finger

Electronic textiles could allow a person to control household appliances or computers from a distance simply by touching a wristband or other item of clothing -- something that could be particularly helpful for those with limited mobility. Now researchers, have developed a new type of e-textile that is self-powered, highly sensitive and washable. A video of an e-wristband in action is available.


Automated robotic device for faster blood testing

Researchers have created an automated blood drawing and testing device that provides rapid results, potentially improving the workflow in hospitals and other health-related institutions to allow health care practitioners to spend more time treating patients.


Novel microplate 3D bioprinting platform for muscle & tendon tissue engineering

New research describes the development of a novel screening platform with automated production of 3D muscle- and tendon-like tissues using 3D bioprinting.


Magnetic treatment could help remove 'off-flavor' from wines



Posted: 13 Jun 2018 07:19 AM PDT


From vine to wine, grapes undergo a remarkable transformation. But sometimes this makeover results in vino that doesn't taste quite right. Scientists now report that they have found a way to use tiny magnetic particles to remove off-tasting substances in cabernet sauvignon without altering its desired bouquet. Eventually, they say this technique could help remove unwanted flavors from other wines.
