A Pitt and Carnegie Mellon team developed a new model of how self-repairing materials function and show that materials with a certain number of easily breakable bonds can absorb more stress, a natural trick found in the resilient abalone shell.

Researchers at Brown may have come across the right formula to deter bacterial migrants. The group reports two ways in which it modified the surface of titanium leg implants to promote skin cell growth, thereby creating a natural skin layer and sealing the gap where the device has been implanted into the body. The researchers also created a molecular chain to sprinkle skin-growing proteins on the implant to hasten skin growth.

Small artificial tubes in the veins, so-called stents, dilate the veins and allow the blood to circulate again without hindrance. But after a while, the deposit of cells and blood components starts at these tubes, as well, and thus the blood vessel narrows again. In an international joint project, scientists are now investigating the feasibility, how to change the surface of these tubes so that no unwanted components may no longer be deposited there.

Read moreA new 'templated growth' technique for fabricating nanoribbons of epitaxial graphene has produced structures just 15 to 40 nanometers wide that conduct current with almost no resistance. These structures could address the challenge of connecting graphene devices made with conventional architectures - and set the stage for a new generation of devices that take advantage of the quantum properties of electrons.

Read moreEngineers at Ohio State University have invented a lens that enables microscopic objects to be seen from nine different angles at once to create a 3D image. Other 3D microscopes use multiple lenses or cameras that move around an object; the new lens is the first single, stationary lens to create microscopic 3D images by itself.
