The End of the Battery – Getting All Charged Up over Supercapacitors

Posted on by

“‘Is this for real?’  Doug was referring to an article in the recent issue of Nature Communications on a novel way to mass-produce so-called superconductors on the super-cheap – using no more equipment than the average home CD/DVD burner. Hacked together by a group of research scientists at UCLA, the ingenious technique is a way of producing layers of microscopically nuanced lattices called graphene, an essential component of many superconductor designs. It holds the promise of rapidly dropping prices for what was until now a very expensive process.”

Google Introduces Way to Manage Your Data Beyond the Grave

Posted on by

“Death is Nature’s way of telling you it’s time to get off the Internet. But when you finally shuffle off this mortal coil, you leave something behind: all your email and other digital assets.  That’s a huge problem not only for the deceased—once you’re on the wrong side of the Great Beyond, there’s no way to delete those incriminating messages—but also any relatives who might want to access your (former) life. And it’s a problem Google’s seeking to solve with the new Inactive Account Manager.”

Hacking an Airplane With Only an Android Phone

Posted on by

“So it looks like someone could hack a jetliner. With an Android smartphone. Awesome.  At the Hack In The Box conference in Amsterdam, security consultant Hugo Teso demonstrated PlaneSploit, an app he developed that can take control of certain systems aboard an airplane and cause it to change direction or just crash itself into the ground.  Hugo’s no terrorist, mind you. He developed the app to point out the glaring, frightening, insane security holes in most planes’ onboard flight systems. His demonstration was done in a simulated environment, but the methods and effects, he says, are exactly the same as what could happen with a real plane.”

Make A Foldable Mini-Spectrometer For Your Phone

Posted on by

“What we perceive as a single color consists of multiple blended colors- just as green paint can be made from mixing yellow and blue paint. A spectrometer is a device that splits light into the various colors it is composed of, which we otherwise cannot distinguish with the naked eye. By viewing a substance through a spectrometer, one can distinguish the exact mixture of colors, which correspond to specific wavelengths of light. These can be compared to other spectra to help identify the sample.”

Biofuel breakthrough turns virtually any plant into hydrogen

Posted on by

“Researchers at Virginia Tech announced Thursday that their latest breakthrough in hydrogen extraction technology could lead to widespread adoption of the substance as a fuel due to its ease of availability in virtually all plant matter, a reservoir previously impossible to tap.  The new process uses a cocktail of 13 enzymes to strip plant matter of xylose, a sugar that exists in plant cells. The resulting hydrogen is of an such a ‘high purity’ that researchers said they were able to approach 100 percent extraction, opening up a potential market for a much cheaper source of hydrogen than anything available today.”

6-meter tall KamerMaker to 3D print Amsterdam house by year’s end

Posted on by

“It is surely now but a matter of time before we are reporting on the completion of the first 3D-printed house. Amsterdam-based DUS Architects is the latest company to show its hand, and has developed its own 3D printer, the 6-meter (20-foot) tall KamerMaker (literally, RoomMaker), with the intention of 3D printing a house before the end of the year.  The intention is that the KamerMaker will print building components on site. The machine can print components, fabricated from polypropylene, up to 2.2 by 2.2 by 3.5 meters (7.2 by 7.2 by 11.5 feet) in size. It’s hoped that in future the KamerMaker will be able to print objects from recycled plastic.”

Scientists use 3D printer to make tissue-like material

Posted on by

“British scientists have used a custom-made 3D printer to make living tissue-like material that could one day serve medical purposes, according to findings released Thursday.
The material is made up of thousands of connected water droplets, encapsulated within lipid films, that can carry out some of the functions of human cells.  These ‘droplet networks’ could be the building blocks of a new technology used to pass on drugs and, down the road, could even replace damaged tissue, said a statement from Oxford University, where the scientists are based. Their findings were published in Friday’s issue of the US journal Science.”

Scientists used modified T-cells to wipe out childhood leukemia in a little girl

Posted on by

“US researchers on Monday reported encouraging success with a new type of immune cell therapy that wiped out leukemia in a young girl by using her own modified T cells to fight the cancer.  The case study of Emily ‘Emma’ Whitehead, age 7, offers hope for a new path against a stubborn form of leukemia, known as acute lymphoblastic leukemia (ALL), maybe even replacing the need for chemotherapy and bone marrow transplants someday.  An attempt at T cell reprogramming in another child who did not survive pointed to the need for more research to improve on the therapies being tested.”

Science Fiction Comes Alive as Researchers Grow Organs in Lab

Posted on by

“Since a laboratory in North Carolina made a bladder in 1996, scientists have built increasingly more complex organs. There have been five windpipe replacements so far. A London researcher, Alex Seifalian, has transplanted lab-grown tear ducts and an artery into patients. He has made an artificial nose he expects to transplant later this year in a man who lost his nose to skin cancer.  Sir Roy Calne, an 82-year-old British surgeon, figured out in the 1950s how to use drugs to prevent the body from rejecting transplanted organs.  Now, with the quest to build a heart, researchers are tackling the most complex organ yet.”

NASA slams spending cuts that put Earth at risk of undetected killer asteroids

Posted on by

“A trio of experts testified before the House Science Committee of the U.S. Congress on Tuesday and warned that the detection and early warning of approaching Near Earth Objects (NEOs) and other threats from space is imperiled by current political wrangling over the national budget.   Holdren, Shelton and Bolden emphasized that while odds of a devastating strike from an object from space are small, the consequences could be enormous. While dozens of objects a meter or more in size strike the Earth’s atmosphere every year, most burn up harmlessly in the upper limits of the stratosphere.”
