Car Crash Videos Highlight Risk of Multitasking With Phones

Memo to parents: Distracted driving by teenagers is riskier than previously thought, particularly when it comes to multitasking with a cellphone. Bits reports.

quotemarksright.jpgThis is one finding of research being published on Wednesday that provides sobering video evidence of the extent and nature of the problem.

The study entailed putting video cameras in the cars of drivers ages 16 to 19, allowing researchers to watch the excruciating moments before nearly 1,700 crashes. Time and time again, teenagers in the videos — which will be made available to the public — lose themselves in their devices and then are jarred back to reality when they slam into another car or careen off the road.

The study, published by the AAA Foundation for Traffic Safety, found that distraction was the cause of roughly 60 percent of moderate and severe crashes. The study says this is four times as many as some previous government estimates.

Cellphones were involved in 12 percent of those crashes, making them the second-highest risk factor. Only teenage drivers’ interaction with other passengers — which caused 15 percent of the wrecks — was a factor in more crashes. In the case of phones, drivers manipulating the device had their eyes off the road for an average of 4.1 seconds in the six seconds before a crash, making them effectively blind to roadway conditions.quotesmarksleft.jpg

3DPrinting

Dentists will soon be able to 3D print you a new tooth in minutes

With the announcement of a breakthrough technology that accelerates 3D printing speeds by a factor of up to 100, you may soon encounter a 3D printer in the most banal of everyday places: your dentist?s office. Quartz reports.

quotemarksright.jpgThis means that dentists can now print a tooth in 6.5 minutes,? explained Joseph DeSimone, the CEO of the 3D printing company Carbon3D and a professor of chemistry at the University of North Carolina at Chapel Hill, at the TED Conference in Vancouver last week.

The 3D printing innovation is cutting edge, but the ability to reproduce a tooth while you wait in the dental chair is actually not new. ?It?s been around for about 30 years,? explains Dr. Sharde Harvey, a New York City-based dentist who been using the method called CEREC (Chairside Economical Restoration of Esthetic Ceramics) since 2005.

Developed in the University of Zurich, CERAC is more akin to computer-assisted sculpture than printing. While 3D printing creates an object one micro layer at a time, CEREC carves out or ?mills? a new tooth from a piece of porcelain aided by scanners and 3D modeling software.

Both methods allow dental practitioners to replace teeth, crowns, veneers, and inlays in a single sitting. The advantage of 3D printing over milling is that the process is better able to custom manufacture an object with intricate details?think about a tooth?s irregular grooves, crannies, and valleys. The problem with 3D printing was that it used to take a very long time.

Now the race is on to come up with faster, feasible 3D printing techniques. Barely a week after Carbon3D?s unveiling, the Australian company Gizmo 3D announced that they?re working on a ?super fast SLA [stereolithography] style 3D printer? that challenges Carbon3D?s print speeds.quotesmarksleft.jpg

The Good Drone

Drones Beaming Web Access Are in the Stars for Facebook
drones-master675.jpg In classical mythology, Aquila is the eagle carrying Jupiter’s thunderbolts skyward. At Facebook, it is the code name for a high-flying drone, indicative of the social networking company’s lofty ambitions. [via The New York Times]

quotemarksright.jpgThe V-shaped unmanned vehicle, which has about the wingspan of a Boeing 767 but weighs less than a small car, is the centerpiece of Facebook’s plans to connect with the five billion or so people it has yet to reach.

Taking to the skies to beam Internet access down from solar-powered drones may seem like a stretch for a tech company that sells ads to make money. The business model at Facebook, which has 1.4 billion users, has more in common with NBC than Boeing.

But in a high-stakes competition for domination of the Internet, in which Google wields high-altitude balloons and high-speed fiber networks and Amazon has experimental delivery drones and colossal data centers, Facebook is under pressure to show that it, too, can pursue projects that are more speculative than product.quotesmarksleft.jpg
