Phoghat (1288088) writes "There’s no cure for type 2 diabetes right now, and even with the best practices and therapies, healthy glucose levels are hard to achieve. Now researchers say they're onto a potential treatment that can restore normal insulin activity, normalizing blood sugar levels with just one injection. So far it works without adverse side effects, at least in mice. An international team led by Michael Downes and Ronald Evans from the Salk Institute for Biological Studies investigated a promising protein called fibroblast growth factor 1 (FGF1). In this study, the researchers injected the protein into the bloodstream of diabetic mice and found a potent, glucose lowering effect — without weight gain, bone loss, or fatty buildup in the liver."

Phoghat (1288088) writes "Using the principle of Electrowetting, Liquavista is developing a range of products based on a variety of architectures. Available in 3 distinct modes; transmissive, reflective and transflective, Liquavista’s technology is the only solution, other than LCD, which operates in all 3 modes modes, but with 2x, 3x, 4x optical performance. Liquavista’s display cell concepts allow radically brighter and more efficient flat panel displays to be built – but use today’s established manufacturing infrastructure and processes to achieve it. The combination of superior performance, lower bill of materials and compatibility with existing infrastructure makes Liquavista’s technology unique. Liquavista owns the core patents on the technology built around work done by the founding team at Philips Research. The performance of Liquavista technology makes it well suited for use in mobile applications such as e-readers, mobile phones, GPS devices, portable media players and cameras because of the ability to see displays in all lighting conditions combined with the ability to show video content at very low power. Furthermore, the scalability of the technology, being based on conventional manufacturing processes, allows for application in large display products such as laptops and tv’s in the long term. I think in the coming months, Amazon is going to challenge Apple for tablet supremacy" Link to Original Source top
Phoghat (1288088) writes "A new low-cost 3D printer developed by Michigan Technological University's Joshua Pearce and his team could add hammers to the list of items you can print at home. The detailed plans, software and firmware are all freely available and open-source, meaning anyone can use them to make their own metal 3D printer. The work is described in "A Low-Cost, Open-Source Metal 3-D Printer," to be published Nov. 25 in IEEE Access" Link to Original Source top
Things you can bring on a plane: A homemade shotgun.
Phoghat (1288088) writes "Evan Booth hacks together working weapons--like a shotgun, a grenade, and a crossbow--with purchases anyone can make after they go through security, to show that the TSA is more spectacle than real protection. And the FBI is taking notice." Link to Original Source top
Phoghat (1288088) writes "IF you get enough batteries entangled, you become so arbitrarily close to the thermodynamic limit that you can consider the energy exchange ‘almost perfect’ (because, you can’t have a perfect energy exchange without violating thermodynamics). There are flaws though: no one knows how to build such a battery using current technology. Another is that even if there were a way, the practicalities of building a real battery would likely introduce inefficiencies into the system, removing its perfection." Link to Original Source top
Phoghat (1288088) writes "The guys at Glassdoor have compiled a list of the 25 tech companies with the best salaries for software engineers. Google and Facebook made the list, of course. So did Apple and Twitter. But the company at the very top is a bit of a surprise: networking gear maker Juniper Networks." Link to Original Source top
Phoghat (1288088) writes "I'm of a "certain age" and as a child grew up watching shows like "Rocky Jones, Space Ranger and others popular at the dawn of the space age. They always showed rocket ships sitting on ther tails and blasting off, and landing, straight up. The shuttle went up that way but had to land like a plane, and anything else was considered impossible or impractical. Now, the Space X rocket Grasshopper can not only do that, but has demonstrated sideways flight also." Link to Original Source top
Phoghat (1288088) writes "Paul Elio has purchased a factory in Tennessee and will be producing the Elio three wheeled vehicle. Production is starting up, and the first cars will be on sale in Summer of 2014. The retail price is set at $6,800, the lowest priced car in the United States. It is reported to get 84 mpg, and will have an 8 gallon tank ( for a range of about 670 miles per tank, and have a top speed of over 100 mph. It seats 2, in a tandem arrangement, and will have space for groceries. Currently classed as a motorcycle, as it has 3 wheels in a pollywog arrangement, it will probably not require helmet use, because it is fully enclosed." Link to Original Source top
Phoghat (1288088) writes "“We are here,” writes the paleontologist Stephen Jay Gould, “because one odd group of fishes had a peculiar fin anatomy that could transform into legs for terrestrial creatures; because comets struck the earth and wiped out dinosaurs, thereby giving mammals a chance not otherwise available.” Vonnegut’s son, the physician Mark Vonnegut, takes a more ethical slant, emphasizing our emotional and physical interconnectedness. “We are here to help each other get through this thing.” The poet W. H. Auden is only superficially similar: “We were put here on earth to help others. I’m not sure what others were put here for.”" Link to Original Source top
Phoghat writes "23andMe is a privately held personal genomics and biotechnology company based in Mountain View, California that provides rapid genetic testing. The company is named for the 23 pairs of chromosomes in a normal human cell. Their personal genome test kit was named "Invention of the Year" by Time magazine in 2008. The test originally cost $1,000 back in 2007, now only $99. Find out what percentage Neanderthal you are !" Link to Original Source top
Phoghat writes "A top defense and cybersecurity expert says the U.S. should stop trying to take aim at expert hackers and start doing a better job of recruiting them. "Let's just say that in some places you find guys with body piercings and nonregulation haircuts," U.S. Naval Postgraduate School professor John Arquilla , "But most of these sorts of guys can't be vetted in the traditional way. We need a new institutional culture that allows us to reach out to them."" Link to Original Source top
Phoghat writes "Could mirror universes or parallel worlds account for dark matter — the ‘missing’ matter in the Universe? In what seems to be mixing of science and science fiction, a new paper by a team of theoretical physicists hypothesizes the existence of mirror particles as a possible candidate for dark matter. An anomaly observed in the behavior of ordinary particles that appear to oscillate in and out of existence could be from a “hypothetical parallel world consisting of mirror particles,” says a press release from Springer. “Each neutron would have the ability to transition into its invisible mirror twin, and back, oscillating from one world to the other.”" Link to Original Source top
Was a Fifth Giant Planet Expelled from Our Solar S
Phoghat writes "Today would have been Carl Sagan’s 77th birthday, and the past few years November 9th has been designated as “Carl Sagan Day” by people who appreciate Sagan’s influence — not only on science, but also the public’s understanding of it. We asked our readers to share their favorite Saganese: their most cherished quotes from the man who has inspired many. Here are our readers’ favorite quotes, images and videos:" Link to Original Source top
Phoghat writes "A Japanese supercomputer has just smashed its own processing speed record, becoming (and remaining) the world’s fastest supercomputer. Japan’s ‘K-computer’ held the record of 8 quadrillion (a quadrillion is a thousand trillion, a petaflop, if you prefer) calculations per second. It has a brain consisting of 88,000 processor microchips and now clocks in at a mind-boggling 10 quadrillion calculations a second, over its 8 quadrillion record at a stunning 93% accuracy. An ordinary desktop, having two or four microchips units, clocks in at about a gigaflop (one thousandth of a trillion), which is a million times lesser than a quadrillion. Ten petaflops is mindblowing! It will be interesting to see the giant solving real problems in the sciences in the near future." Link to Original Source top
Phoghat writes "A huge defunct satellite is soon to come crashing down to the Earth in a few days time, but NASA assures everyone that no one will get hurt! The satellite in question is the Upper Atmospheric Research Satellite (UARS). The date for the crash is 24th September. The crash window, earlier announced to be between late September and early October, has now been curtailed to just three days." Link to Original Source top
GRAIL and the Mystery of the Missing Moon - NASA S
Phoghat writes "Did our planet once have two moons? Some researchers say so. Moreover, the missing satellite might still be up there--splattered against the far side of the Moon. NASA's GRAIL mission, due to launch on Sept. 8th, could help confirm or refute the "two moon" hypothesis." Link to Original Source top
"Aluminum-Celmet" could boost electric vehicle ran
Phoghat writes "The fear that EV's will leave the vehicle's occupants stranded well short of their destination, remains one of, if not the main barrier to the widespread adoption of EVs. A new material developed by Japanese company Sumitomo Electric could help allay such fears by potentially improving the capacity of lithium-ion batteries by 1.5 to three times, and therefore extending the range of EVs by an extra 50 to 200 percent. That would give a Nissan Leaf a range of up to 109 to 219 miles (175 to 352 km) or a Tesla Roadster (which would be MY CHOICE a range of up to 366 to 732 miles (589 to 1,178 km) — enough to assuage the range anxiety of the most fretful drivers."

Phoghat writes "Voyager, Proteus and SpaceShipOne have become aerospace legends. As has the man who established them all – Burt Rutan. Zenith Press has released a chronicle of the man and his machines entitled."Burt Rutan’s Race to Space: The Magician of Mojave and His Flying Innovations" The book provides a chronicle of all the air and spacecraft that have soared off of Rutan’s blueprints and into reality. The book’s first main segment is a large section which is essentially a catalog of the numerous craft that Rutan has produced over the decades. Many of the flying machines have their unique characteristics highlighted within the 160 pages of this book. Fear not, this tome is wallpapered with images – most of which are color (175 color images to 55 black and white). Some of the most interesting of these images are not the glossy stills of air or spacecraft in action but rather the simple drawings that are done by the man himself. These sketches, some little more than cartoons others just simplistic line-drawings, highlight the genius that is Rutan and provide an insight into how his mind works. The nature of the book changes somewhat when one reaches the chapter entitled, “The Scaled Composites Years.” From this point on, the book’s focus narrows to concentrate on Rutan’s X-PRIZE efforts – and beyond. The book was written by Dan Linehan and is his second detailing the efforts of Rutan and Scaled Composites (the first was "SpaceShipOne: An Illustrated History " ). In short, the freelance writer is steeped in all things Rutan. Whereas his first work on the subject covered the history-making flight of SpaceShipOne, this effort is a general overview of Rutan and his legacy. But be forewarned, there are many projects that span the entire realm of aerospace that Rutan and company have been involved with that might surprise you." Link to Original Source
