European Banks have unlimited borrowing from the European Central Bank

Businessweek – European banks may borrow as much next month from the European Central Bank as they did in a record offering in December as they seek refuge from frozen funding markets. Basically Germany agreed to open up the printing presses to fund the ECB and thus the banks of Europe. This should prevent/limit any …

Metamaterial for Gecko toes for controlled adhesion to any surface

Arxiv – Metamaterial ‘Gecko Toe’: Optically-Controlled Adhesion to Any Surface (5 pages) On the mesoscopic scale, electromagnetic forces are of fundamental importance to an enormously diverse range of systems, from optical tweezers to the adhesion of gecko toes. Here we show that a strong light-driven force may be generated when a plasmonic metamaterial is illuminated …

Photoinduced write-once read-many-times memory device based on DNA biopolymer nanocomposite

Eurekalert – In an effort to make data storage more cost-effective, a group of researchers from National Tsing Hua University in Taiwan and the Karlsruhe Institute of Technology in Germany have created a DNA-based memory device that is “write-once-read-many-times” (WORM), and that uses ultraviolet (UV) light to make it possible to encode information. The device, …

Passive Optical Diode could bring optical information processing with millions fitting on a computer chip

Researchers have created a new type of optical device small enough to fit millions on a computer chip that could lead to faster, more powerful information processing and supercomputers. The “passive optical diode” is made from two tiny silicon rings measuring 10 microns in diameter, or about one-tenth the width of a human hair. Unlike …
