May 1, 2013 — Scientists at Princeton University used off-the-shelf printing tools to create a functional ear that can "hear" radio frequencies far beyond the range of normal human capability. The researchers' primary purpose was to explore an efficient and versatile means to merge electronics with tissue. The scientists used 3D printing of cells and nanoparticles followed by cell culture to combine a small coil antenna with cartilage, creating what they term a bionic ear.

Imagine that the chips in your smart phone or computer could repair and defend themselves on the fly, recovering in microseconds from problems ranging from less-than-ideal battery power to total transistor failure. It might sound like the stuff of science fiction, but a team of engineers at the California Institute of Technology (Caltech), for the first time ever, has developed just such self-healing integrated chips. The team, made up of members of the High-Speed Integrated Circuits laboratory in Caltech's Division of Engineering and Applied Science, has demonstrated this self-healing capability in tiny power amplifiers.

3D-printer with nano-precision Printing three dimensional objects with incredibly fine details is now possible using "two-photon lithography". With this technology, tiny structures on a nanometer scale can be fabricated. Researchers at the Vienna University of Technology (TU Vienna) have now made a major breakthrough in speeding up this printing technique: The high-precision-3D-printer at TU Vienna is orders of magnitude faster than similar devices (see video). This opens up completely new areas of application, such as in medicine. The 3D printer uses a liquid resin, which is hardened at precisely the correct spots by a focused laser beam. The focal point of the laser beam is guided through the resin by movable mirrors and leaves behind a polymerized line of solid polymer, just a few hundred nanometers wide. 3D-printer with nano-precision
Tough gel stretches to 21 times its length, recoils, and heals itself CONTACT: Caroline Perry, (617) 496-1351 Cambridge, Mass. - September 5, 2012 - A team of experts in mechanics, materials science, and tissue engineering at Harvard have created an extremely stretchy and tough gel that may pave the way to replacing damaged cartilage in human joints. Called a hydrogel, because its main ingredient is water, the new material is a hybrid of two weak gels that combine to create something much stronger. Not only can this new gel stretch to 21 times its original length, but it is also exceptionally tough, self-healing, and biocompatible—a valuable collection of attributes that opens up new opportunities in medicine and tissue engineering. The material, its properties, and a simple method of synthesis are described in the September 6 issue of Nature. The researchers pinned both ends of the new gel in clamps and stretched it to 21 times its initial length before it broke. Tough gel stretches to 21 times its length, recoils, and heals itself
Low-cost, finger-nail sized radar Low-cost, finger-nail sized radar Nov. 23, 2012 — EU-funded 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. Developed in the 'Silicon-based ultra-compact cost-efficient system design for mm-wave sensors' (Success) project, the device is the most complete silicon-based 'system-on-chip' (SoC) package for radar operating at high frequencies beyond 100 GHz. 'As far as I know, this is the smallest complete radar system in the world,' says Prof.
For the first time, MIT researchers have shown they can genetically engineer viruses to build both the positively and negatively charged ends of a lithium-ion battery. The new virus-produced batteries have the same energy capacity and power performance as state-of-the-art rechargeable batteries being considered to power plug-in hybrid cars, and they could also be used to power a range of personal electronic devices, said Angela Belcher, the MIT materials scientist who led the research team. Angela Belcher holds a display of the virus-built battery she helped engineer. The battery -- the silver-colored disc -- is being used to power an LED.

His charitable organisation, the Bill & Melinda Gates Foundation, is looking for future loos that can improve sanitation around the world. At the Reinvent the Toilet fair, hosted at its Seattle campus this week, designs included a lavatory that used microwave energy to turn poo into electricity. Another turned excrement into charcoal, while a third used urine for flushing. Bill Gates looks to new toilets to improve world sanitation Bill Gates looks to new toilets to improve world sanitation
Less than a month after Apple first shipped the iPhone in June 2007, a group called Independent Security Evaluators documented deep security design flaws in the device. Apple’s most embarrassing flub: every iPhone application that Apple had written ran with so-called root privileges, giving each one complete control over the entire phone. Hackers found bugs in those apps that could be used to take over the phone from the inside. Apple didn’t fix the design flaw until January 2008.

Viewpoint: Changing the way the internet is governed is risky Viewpoint: Changing the way the internet is governed is risky 14 June 2012Last updated at 23:01 GMT By Prof Alan Woodward Department of Computing, University of Surrey Many people may be unaware that the US Department of Commerce has the power to decide how the internet works Governance is the establishment and enforcement of norms, rules and decision-making procedures. It is not the "law" as such, but rather a structure by which everyone agrees to abide, which can be captured locally by specific laws.
Entropy can lead to order, paving the route to nanostructures Researchers trying to herd tiny particles into useful ordered formations have found an unlikely ally: entropy, a tendency generally described as "disorder." Computer simulations by University of Michigan scientists and engineers show that the property can nudge particles to form organized structures. By analyzing the shapes of the particles beforehand, they can even predict what kinds of structures will form. The findings, published in this week's edition of Science, help lay the ground rules for making designer materials with wild capabilities such as shape-shifting skins to camouflage a vehicle or optimize its aerodynamics. Physicist and chemical engineering professor Sharon Glotzer proposes that such materials could be designed by working backward from the desired properties to generate a blueprint.

Brain-Scanning Binoculars Harness Soldiers' Unconscious Minds to Locate Threats Soldiers scanning the battlefield for threats may soon get a new tool: a brain-scanning set of binoculars that can pick up on a soldier's unconscious recognition of a potential threat and bring it to his conscious attention. It's just one of many ways DARPA and other military research groups are looking to have soldiers mind-meld with their machines and materiel, and as the BBC reports, it demonstrates how remarkably close we are to deploying mind-control on the battlefield. The specific binocular device that DARPA is developing is known as Sentinel (for System for Notification of Threats Inspired by Neurally Enabled Learning, because that's not an unwieldy acronym or anything), and it basically uses the power of the human brain to scan and filter imagery in realtime, picking up on both what the soldier recognizes consciously and what his unconscious might perceive as well.

Did you know that you smile when you’re frustrated? Starting at 1:20 in the video below, witness a behavior that you may find novel – and doubly so because you’re a human being who is exquisitely tuned to reading the emotional expressions of others. By training a feature-detecting algorithm to decompose subjects’ facial expressions into individual “action units,” M. Ehsan Hoque of the MIT Media Lab discovered not only that smiling is quite common when test subjects are frustrated, but also that software is better than humans at differentiating frustration smiles from happiness smiles. Software Better at Detecting Frustration Than Humans

News in Science Monday, 16 April 2012 Darren OsborneABC Counting on nothing Quantum fluctuations within a vacuum are helping Australian researchers create billions of random numbers. The random number generator, created by Professor Ping Koy Lam, Dr Thomas Symul and Dr Syed Assad from the Australian National University (ANU), uses highly sensitive light detectors to 'listen' to an empty space. Until recently a vacuum was thought to be completely empty. But modern quantum theory now suggests that it is filled with virtual sub-atomic particles spontaneously appearing and disappearing, creating random noise. Nothing helps create pure randomness › News in Science (ABC Science)
