Submission + - Cell Transplant Enables Paralyzed Man to Walk Again (gizmag.com)

Zothecula writes: In 2010, Darek Fidyka was paralyzed from the chest down as a result of a knife attack that left an 8 mm gap in his spinal column. Now surgeons in Poland, working in collaboration with scientists in London, have given Fidyka the ability to walk again thanks to a new procedure using transplanted cells from his olfactory bulbs.

Submission + - Radical 4-in-1 Piston Engine Promises Hybrid-Like Efficiency (gizmag.com)

Zothecula writes: One of the many challenges facing engine designers is the need to increase power output while simultaneously retaining or improving efficiency. Although a four-cylinder engine is still an engineering marvel, there remain many friction points that reduce energy output. Namikoshi Electronics of Japan believes its unorthodox 4-in-1 concept engine could provide an alternative powerplant to the automobile industry.

Submission + - New Li-ion Anode Achieves 70 Percent Charge in Just Two Minutes (gizmag.com)

Zothecula writes: Researchers at the Nanyang Technological University (NTU) in Singapore have developed a new, proof-of-concept anode for lithium-ion batteries that can charge to 70 percent of its capacity in only two minutes and has a very long lifespan of ten thousand charge/discharge cycles. The advance could lead to the production of high-rate lithium-ion batteries, with interesting implications for personal electronics and, perhaps, even electric vehicles.

Submission + - Wasp's 3D Printers Produce Low-Cost Houses Made From Mud (gizmag.com)

Zothecula writes: A need to address a lack of housing for the globe's growing population has turned up some eye-catching efforts, blending creative architecture with new, sustainable technologies. And it is increasingly looking like 3D printing could have a role to play. Italian firm Wasp is the latest to explore the potential of additive manufacturing in this area, developing a super-sized 3D printer capable of producing low-cost housing made from mud.

Submission + - Turning up the Heat to Make Kelp a Viable Source of Biofuel (gizmag.com)

Zothecula writes: Biofuels may indeed offer a greener alternative to fossil fuels, but they do raise at least one concern – crops grown as biofuel feedstock could take up farmland and use water that would otherwise be used to grow crops for much-needed food. That's why some scientists have looked to seaweed as a feedstock. Kelp is particularly attractive, in that it's abundant and grows extremely quickly, although its fuel yields haven't been particularly impressive. That could be about to change, however, thanks to a newly-developed hydrothermal process.

Submission + - Scientists Create World's Thinnest Electric Generator (gizmag.com) 1

Zothecula writes: Researchers from Columbia University and the Georgia Institute of Technology are laying claim to having observed piezoelectricity in an atomically thin material for the first time. The effect was demonstrated in the world's thinnest electric generator made from a two-dimensional molybdenum disulfide (MoS2) material, which had previously been predicted to exhibit such properties.

Submission + - Earth's Magnetic Field Could Reverse in Just One Lifetime (gizmag.com)

Zothecula writes: A new study by a team of scientists from Italy, France, Columbia University and the University of California, Berkeley, demonstrates that the Earth's magnetic field could change polarity in less than 100 years. The last magnetic reversal occurred some 786,000 years ago and was previously thought to have taken several thousand years but, if the researchers are right, the real time it may take for the flip to occur could actually be closer to the span of a human life.

Submission + - Samsung Announces Super Fast, 4.6 Gbps Wi-Fi Technology (gizmag.com)

Zothecula writes: Samsung Electronics has developed a new Wi-Fi technology that it says will soon allow users to download a 1 GB movie in less than three seconds, or stream uncompressed high-definition videos from mobile devices to TVs in real-time. The company also claims that the 802.11ad standard, 60 GHz Wi-Fi technology will to enable maximum speed irrespective of the number of devices connected to the same network.

Submission + - Submersible Exosuit Lets Divers Plunge to 1,000 ft Below the Surface (gizmag.com)

Zothecula writes: Thanks largely to Hollywood blockbuster franchises, humanity seems to be in the grips of a global obsession with exosuits. The fixation is informing the designs of future military tech and may even play a role in how we operate in space. Canadian based Nuytco Research hopes to bring its own Exosuit to the sea floor, allowing divers to safely operate at depths of up to 1,000 ft (305 m) with none of the nasty pressure-induced side effects that so often ruin a deep sea diver's day.

Submission + - Prosthetic Hand Capable of Delivering Texture Sensations (gizmag.com)

Zothecula writes: A new prosthetic system allows amputees to feel familiar sensations and also, somewhat unexpectedly, reduces their phantom pain. Researchers at Case Western Reserve University and the Louis Stokes Cleveland Veterans Affairs Medical Center developed the system to reactivate areas of the brain that produce the sense of touch, but recipients of prosthetic hands reported their phantom pain subsiding almost completely after being hooked up to the system.

Submission + - New Tech Brings Together Real and Virtual in Augmented Reality Reflections (gizmag.com)

Zothecula writes: Perhaps you've been in a situation where you noticed that your reflection in a window looked like it was actually standing amongst the items that were visible through that window. Now, scientists at the University of Bristol have taken that phenomenon and incorporated it into an experimental new interactive display. Among other things, it lets users select objects seen through a pane of glass, using the reflection of their finger on that glass.

Submission + - Signing Robot Developed as Chatty Companion for the Elderly (gizmag.com)

Zothecula writes: Following in the footsteps of Hiroshi Ishiguro's eerily lifelike creations, Toshiba introduced its very own take on the human-looking droid at Japan's CEATAC electronics trade show this week. The communication android has been built to communicate in Japanese sign language, requiring fluid and precise movement of its arms and hands.

Submission + - European Scientists Developing a Robotic Tree (gizmag.com)

Zothecula writes: The animal kingdom contains many examples of efficient forms of locomotion, so it's no wonder that we've been seeing a lot of animal-inspired robots. Plants, however, just sit there ... don't they? Actually, they do move, just not necessarily in a Point A to Point B manner. With that in mind, Europe's PLANTOID project consortium is now in the process of developing a tree-like robot. Its descendants might ultimately find use in the exploration of other planets.

Submission + - World's First Solar Battery Claimed to "Run on Light and Air" (gizmag.com)

Zothecula writes: Researchers at Ohio State University (OSU) have created a dye-sensitized solar cell that stores its own power by "breathing" air to decompose and re-form lithium peroxide. Its creators believe the device, which effectively combines a battery and a solar cell in one, could reduce renewable energy costs by 25 percent.
