| Pacemakers with Internet connection, a not-so-distant goal Posted: 28 Jan 2015 08:37 AM PST An efficient security protocol has been designed to protect the information provided by pacemakers and similar medical devices connected to the Internet. Thanks to the latest advances in microelectronics and communications technologies, it is not difficult to imagine a future with medical sensors connected to the Internet. Now, thanks to a group of researchers, a little more progress has been made in the area of the remote monitoring of patients by means of implanted sensors.  |
| Researchers use sound to slow down, speed up, and block light Posted: 28 Jan 2015 06:35 AM PST How do you make an optical fiber transmit light only one way? Researchers have experimentally demonstrated, for the first time, the phenomenon of Brillouin Scattering Induced Transparency (BSIT), which can be used to slow down, speed up, and block light in an optical waveguide. The BSIT phenomenon permits light to travel in the forward direction while light traveling in the backward direction is strongly absorbed. This non-reciprocal behavior is essential for building isolators and circulators.  |
| Nanoscale mirrored cavities amplify, connect quantum memories Posted: 28 Jan 2015 05:18 AM PST Constructing tiny "mirrors" to trap light increases the efficiency with which photons can pick up and transmit information about electronic spin states -- which is essential for scaling up quantum memories for functional quantum computing systems and networks.  |
| Maximizing access to mobile networks by seamlessly 'offloading' some traffic Posted: 27 Jan 2015 06:58 AM PST Mathematical analysis reveals how to maximize access to mobile networks by seamlessly 'offloading' traffic to smaller Wi-Fi and cellular systems.  |
| Stock market changes: Patents provide insight into Wall Street 'technology arms race' Posted: 26 Jan 2015 06:59 AM PST A new study has used US patent data to shed light on the technological roots behind Wall Street's ongoing 'technology arms race.' The way financial assets are traded, and the nature of the markets themselves, has dramatically changed over the last two decades, according to new research.  |
