Materials science: One size cloaks all Posted: 23 Nov 2012 10:26 AM PST Scientists have developed a metamaterial invisibility cloak that can adapt to hide different sized objects. The findings represent a useful advance for more practical applications of metamaterial cloaking.

Polymer chemistry: Dual-function molecules enhance widely used chemical reaction while reducing harmful by-products Posted: 23 Nov 2012 10:26 AM PST Production of biocompatible and super-absorbent materials may become easier. Using a modification to the high-precision technique known as atom transfer radical polymerization (ATRP), which links molecules into long chains, researchers have developed new compounds that can directly polymerize acidic vinyl monomers, such as acrylic acid.

Wireless networks: Mobile devices keep track Posted: 23 Nov 2012 10:26 AM PST A more sensitive technique for determining user position could lead to improved location-based mobile services.

Improving 3-D image capture in real time Posted: 23 Nov 2012 07:37 AM PST Researchers have developed a technique to improve the capture in real time of three-dimensional images. The work has applications in aeronautics, the automotive sector and operating rooms.

Hubble eyes a loose spiral galaxy Posted: 23 Nov 2012 06:37 AM PST The NASA/ESA Hubble Space Telescope has spotted the spiral galaxy ESO 499-G37, seen here against a backdrop of distant galaxies, scattered with nearby stars.

Low-cost, finger-nail sized radar Posted: 23 Nov 2012 06:27 AM PST Researchers have squeezed radar technology into a low-cost fingernail-sized chip package that promises to lead to a new range of distance and motion sensing applications. The novel device could have important uses in the automotive industry, as well as mobile devices, robotics and other applications.

Electricity from the marshes Posted: 23 Nov 2012 06:21 AM PST An unexpected source of new, clean energy has been found: the Plant-Microbial Fuel Cell that can generate electricity from the natural interaction between living plant roots and soil bacteria. The technique already works on a small scale and will soon be applied in larger marshland areas throughout the world.

Blind patient reads words stimulated directly onto retina: Neuroprosthetic device uses implant to project visual braille Posted: 22 Nov 2012 06:54 AM PST For the very first time researchers have streamed braille patterns directly into a blind patient's retina, allowing him to read four-letter words accurately and quickly with an ocular neuroprosthetic device.

Scientists design a revolutionary data storage device Posted: 22 Nov 2012 06:53 AM PST Scientists have designed one of the most advanced data storage devices in the world.

IT building blocks for the ordinary person Posted: 21 Nov 2012 04:57 AM PST Would you like to create your own tourist guide? Or put together telecom services that give you better control of the everyday functions on your phone? We seem to be drowning in 'intelligent things' and IT services. In our smart home, we can use various applications to control the front door, TV, washing machine, vacuum, heating and blinds. Other apps enable us to find out what time the bus is leaving, or book a table at a restaurant. On the medical side, there are sensors that can monitor your heart rate, intelligent pill boxes that remember when you should take your medicine, and applications to notify relatives if an elderly person doesn't get out of bed at their normal time. But what if you go on holiday, and want to be able to water the plants in your garden, or turn the heating on or off in a certain room when the weather changes?

Scotch tape finds new use as grasping 'smart material' Posted: 20 Nov 2012 01:09 PM PST Scotch tape, a versatile household staple and a mainstay of holiday gift-wrapping, may have a new scientific application as a shape-changing "smart material."

Filtering spam: New method to rid inboxes of unsolicited email Posted: 20 Nov 2012 09:20 AM PST Spammers have recently turned high-tech, using layers of images to fool automatic filters. Thanks to some sophisticated new cyber-sleuthing, researchers are working toward a cure.
