A new device developed at The Ohio State University can start healing organs in a "fraction of a second," researchers say.
The technology, known as Tissue Nanotransfection (TNT), has the potential to save the lives of car crash victims and even deployed soldiers injured on site. It's a dime-sized silicone chip that "injects genetic code into skin cells, turning those skin cells into other types of cells required for treating diseased conditions," according to a release.
In lab tests, one touch of TNT completely repaired injured legs of mice over three weeks by turning skin cells into vascular cells.
*A better solution would be to somehow capture the fats and oils before they hit the sewers...Recycling R US As a kid, we saved the cooking grease in a metal coffee can...for use later, or put it into the garbage can By Y10K, they'll HAVE to recycle it...or else!
snip>> In the United States, many cities eventually required restaurants and other food sellers to have grease traps and to clean them out, and a surprising amount of controversy and intrigue has grown around these caches of fat. In some places, thieves blowtorch their way into grease traps to steal used cooking oil that can be made into biofuels. --- Yum>>> In China, fat from sewers and traps is illicitly scooped, cleaned up—though not well—and sold on the black market as “gutter oil.” In cheap restaurants and street stalls, your dinner might even be cooked in gutter oil. ---- Some cities are even looking at fatbergs as legitimate fuel. After all, fat is high in calories and therefore energy. Thames Water has partnered with a renewable-fuel company to dig fatbergs out of sewers and turn them into biodiesel. ---------
Quantum messaging in seawater...possibly up to 900m...& beyond msn.com
Scientists have achieved quantum communication in sea water, showcasing a futuristic concept for 'encrypted' underwater information exchange.
In a bid to devise methods for 'unhackable' ways of underwater communication, a team of researchers from Shanghai Jiao Tong University sent information between entangled particles through sea water.
The idea of quantum (secure) communication is not new and several scientists are already working on it, but this is the first instance where information has been transposed in water. The researchers have managed to communicate across a 3.3m long tank of seawater and they say the same mechanism could also be used to send 'unhackable' messages through 900m of open sea water.
To achieve this feat, the scientists followed the concept of quantum entanglement – the idea of linking two distant particles to the point where manipulation of one particle leads to an immediate and automatic reaction from its counterpart. They utilised water's well-known capability of scattering light and a prism to create the entangled particles. Put simply, a beam of light was shot into a crystal to split into a pair linked photons, with exactly opposite polarisation.
With both particles at opposite ends of the tank, the team demonstrated that despite being distant, they were able to transpose accurate information over 98% of the time.
The possible applications of the technique are evident, with the best one being integration with submarines for secure communications. In The Optical Society, the researchers wrote: "Our results confirm the feasibility of a seawater quantum channel, representing the first step towards underwater quantum communication."
The experiment is clearly promising, but as these are nascent stages, it still remains to be seen whether scientists will be able to build on this breakthrough into a future of 'quantum communication' across greater distances.
