Israeli prime minister Benjamin Netanyahu was speaking at a government function in July when a man sitting a few rows behind him pulled a Liberator, the infamous 3D-printed gun that the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) recently defined as a “lethal weapon.”

The gun posed no real danger. The man bearing it was just a TV reporter trying to prove how easy it is to sneak a 3D-printed plastic gun past security checks that include metal detectors.

QUEENSBURY, N.Y. (AP) — Coming soon to your local sheriff: 18-ton, armor-protected military fighting vehicles with gun turrets and bulletproof glass that were once the U.S. answer to roadside bombs during the Iraq war.

The hulking vehicles, built for about $500,000 each at the height of the war, are among the biggest pieces of equipment that the Defense Department is giving to law enforcement agencies under a national military surplus program.

For police and sheriff’s departments, which have scooped up 165 of the mine-resistant ambush-protected vehicles, or MRAPS, since they became available this summer, the price and the ability to deliver shock and awe while serving warrants or dealing with hostage standoffs was just too good to pass up.

A researcher envisions the ultimate cure for “range anxiety”: roadway-powered vehicles with modified on-board power receivers.

• By Martin LaMonica on November 19, 2013

One way to extend the range of electric vehicles may be to provide power wirelessly through coils placed under the surface of a road. But charging moving vehicles with high-power wireless chargers below them is complex.

Researchers at North Carolina State University have developed a way to deliver power to moving vehicles using simple electronic components, rather than the expensive power electronics or complex sensors previously employed. The system uses a specialized receiver that induces a burst of power only when a vehicle passes over a wireless transmitter. Initial models indicate that placing charging coils in 10 percent of a roadway would extend the driving range of an EV from about 60 miles to 300 miles, says Srdjan Lukic, an assistant professor of electrical engineering at NCSU.

Anyone who has left youth behind them knows that bumps and scrapes don’t heal as fast as they used to. But that could change with researchers at the Stem Cell Program at Boston Children’s Hospital finding a way to regrow hair, cartilage, bone, skin and other soft tissues in a mouse by reactivating a dormant gene called Lin28a. The discovery could lead to new treatments that provide adults with the regenerative powers they possessed when very young.

Lin28 is a gene that is abundant in embryonic stem cells and which functions in all organisms. It is thought to regulate the self-renewal of stem cells with the researchers finding that by promoting the production of certain enzymes in mitochondria, it enhances the metabolism of these cellular power plants that found in most of the cells of living organisms. In this way, Lin28 helps generate the energy needed to stimulate the growth of new tissues.

A University of Alabama at Birmingham (UAB) surgical team has performed one of the first surgeries using a telepresence augmented reality technology from VIPAAR in conjunction with Google Glass.

The combination of the two technologies could be an important step toward the development of useful, practical telemedicine.

VIPAAR (Virtual Interactive Presence in Augmented Reality) is commercializing a UAB-developed technology that provides real-time, two-way, interactive video conferencing.

Congress gave the FAA a September 2015 deadline for drones to fly safely with commercial airlines.

The Federal Aviation Administration has a plan for allowing drones to fly everywhere in the country. But research and regulations are months behind the schedule Congress set to have the unmanned devices fly safely with commercial airliners by September 2015.

FAA Administrator Michael Huerta released the five-year road map a month ago. It projected 7,500 unmanned aircraft would be in the skies within that period if regulations are in place.

But the FAA faces technical challenges, among them how much training to require of ground-based pilots, how to ensure that drones fly safely if they lose contact with their pilots and how drones and commercial aircraft should warn each other when they’re in the same area.

BTC China, the nation’s largest Bitcoin exchange, has had low-level discussions with regulators seeking recognition of the digital currency that would allow it to be used to buy goods and services in the country.

The company has sought to discuss Bitcoin regulations with officials from agencies including the People’s Bank of China, the China Banking Regulatory Commission and the China Securities Regulatory Commission, BTC China Chief Executive Officer Bobby Lee said in a Nov. 29 interview in Shanghai. It’s not yet been able to arrange any high-level meetings, he said.

“They’ll ask us ‘how should you be regulated,’ and I’ll say ‘Hey, here’s what we’ve done proactively and here’s how we think you should regulate us,’” Lee said of the Shanghai-based company’s talks with regulators. Bitcoin is “not on the black list and it’s not on the white list. It’s in the gray area.”

For those who haven’t been following along, this recent story about 3D printing of plastic guns should be a revelation. 3D printing is one of those technologies where the reality is fast outrunning our imagination. It is, in essence, the ability to construct a product from feedstock using a readily available “printer” linked to a computer where the source code for the product is executed. According the Washington Post’s story, the new plastic guns are capable of firing lethal rounds and, naturally, they are beyond the detection of metal detectors.

But for every “parade of horrible story” about 3D printing there’s also one of great promise. For example, NASA recently announced plans to send a 3D printer to the space station. This development, combined with the development of printing for metal objects (from liquid metal feedstock) means that many of our concepts of logistics will go out the window. If a manufacturer can construct metal parts from an easily transported feed stock then, as Andrew Filo, a consultant with NASA on the 3D space station printing project, said: “You can get rid of concepts like rationing, scarce or irreplaceable.” That’s a truly extraordinary development.
