Nano fiber feels forces and hears sounds made by cells

Engineers at the University of California San Diego have developed a miniature device that's sensitive enough to feel the forces generated by swimming bacteria and hear the beating of heart muscle cells.

Do-it-yourself invisibility with 3-D printing

Seven years ago, Duke University engineers demonstrated the first working invisibility cloak in complex laboratory experiments. Now it appears creating a simple cloak has become a lot simpler.

Researchers develop printable lasers

(Phys.org)—A way of printing lasers using everyday inkjet technology has been created by scientists. The development has a wide range of possible applications, ranging from biomedical testing to laser arrays for displays.

Chemically assembled metamaterials may lead to superlenses

(PhysOrg.com) -- Nanomanufacturing technology has enabled scientists to create metamaterials -- stuff that never existed in nature -- with unusual optical properties. They could lead to "superlenses" able to image proteins, ...

Smashing metallic cubes toughens them up

Scientists at Rice University are smashing metallic micro-cubes to make them ultrastrong and tough by rearranging their nanostructures upon impact.
