Thought-Controlled Robotic Arm Mimics Real Limb

Researchers developing a thought-controlled robotic arm. Scientists from Tomsk Polytechnic University are developing a robotic arm prototype and its control algorithm using myoelectric signals. The mechanical limb will independently recognize the motions of its owner and perform the same motions as a healthy arm.

3D Printer Produces Cartilage from Strands of Bioink

A multi-arm bioprinter that can print cartilage. (Ozbolat Lab/Penn State) Strands of cow cartilage substitute for ink in a 3D bioprinting process that may one day create cartilage patches for worn out joints. A cartilage strand substitutes for ink in a 3D printing process. Using a specially designed prototype nozzle that can hold and feed the cartilage strand, the 3D printer lays down rows of cartilage strands in any pattern the researchers choose.

Mobile Phone-Based Microscopes Diagnose Parasites in the Field

A local lab technician in the Ivory Coast is being trained on a portable, handheld, battery-operated microscope. (Photo: Dr. Isaac Bogoch) Handheld, mobile phone-based microscopes can be used in developing countries after minimal training of community laboratory technicians to diagnose intestinal parasites quickly and accurately. A community-based study carried out in the Republic of Ivory Coast in West Africa found that two different handheld microscopes could both effectively rule in individuals infected by parasites.

Emerging Trends in Bioabsorbable Vascular Scaffolds

Extensive development efforts towards a Bioabsorbable Vascular Scaffold (BVS) as a clinically superior therapy for the treatment of coronary and peripheral artery disease continues around the world. As advancement continues, engineers are tasked to create a BVS with thinner struts. Additionally, as the utility for BVS based therapies outside the coronary vasculature is explored, an additional host of challenges is likely to be uncovered.
