Checkout clerk's days numbered as printable RFID tags become a reality
Using nanotube transistors, researchers have developed a three-step process to print single-bit RFID tags - including the antenna, electrodes and dielectric layers - onto flexible plastic. The team is now working on 16-bit tags that would hold more information as well as being printable on paper...

Geometry influences stem cell differentiation
Scientists have successfully used geometrically patterned surfaces to influence the development of stem cells into either fat cells or bone cells. The new approach is a radical departure from that of many stem-cell biologists, who focus instead on uncovering the role of proteins in controlling the ultimate fate of stem cells...
