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.

I believe Google is making a huge mistake in completely banning facial recognition systems for its Glass product. In my opinion, such a system could be used to help save thousands of lives. But then, we’re too damn caught up on absolute privacy that we’re willing to sacrifice actual, physical lives to ensure our privacy remains untainted. Such individualist dogma is deadly.

According to the Amber Alert webpage, “A child goes missing in the United States every 40 seconds,” and that “More than 700,000 children go missing annually.” That is an absolutely frightening statistic! Much more frightening than the prospect that some Glass user may know my name.

How far are we willing to go to ensure absolute privacy isn’t diminished whatsoever? When does the right of privacy begin interfering with the right of safety? Can the two come together in harmony, or are they destined to be in conflict until society finally reaches a decision over one or the other?

General Electric (GE), on the hunt for ways to build more than 85,000 fuel nozzles for its new Leap jet engines, is making a big investment in 3D printing. Usually the nozzles are assembled from 20 different parts. Also known as additive manufacturing, 3D printing can create the units in one metal piece, through a successive layering of materials. The process is more efficient and can be used to create designs that can’t be made using traditional techniques, GE says. The finished product is stronger and lighter than those made on the assembly line and can withstand the extreme temperatures (up to 2,400F) inside an engine. There’s just one problem: Today’s industrial 3D printers don’t have enough capacity to handle GE’s production needs, which require faster, higher-quality output at a lower cost.

A college student quickly made over $24,000 just by waving this sign on TV.

Here’s the deal: Yesterday on ESPN’s “College GameDay” (an ESPN college football show that’s filmed at a different college campus each week) some student held the above sign that has both the Bitcoin logo and a QR code.

A QR code is a visual representation of any kind of information (frequently a URL for a website). In this case, the code represented a Bitcoin wallet.

On Reddit, Bitcoin fans managed to enhance the QR code from the screen in order to identify his wallet, so that people could donate money to him.

In the next five years, the Internet retail giant expects to use small drones to deliver packages to customer doorsteps within 30 minutes of their order.

Amazon is testing a delivery service that uses drones to deliver packages within 30 minutes of an order being placed.

Dubbed Amazon PrimeAir, the service uses 8-propeller drones about the size of a remote-controlled airplane to transport shoe-box-size plastic bins from fulfillment centers to customers’ homes. The service, which still requires more testing and clearance from the Federal Aviation Administration, could take to the skies as soon as four to five years, Amazon CEO Jeff Bezos told Charlie Rose during an interview Sunday on “60 Minutes.”
