A Little Lead Can Make Graphene Magnetic

Graphene has very many strengths , but there is one thing it isn't and that is magnetic. Now, a team of researchers has found that the insertion of a little lead into the planar graphene structure can change that.

LG says next year's 4K TVs will be better because of quantum dots

Source: http://www.engadget.com/2014/12/15/lg-4k-quantum-dot-hdtv/

LG has announced that next year, it will have a new set of 4K TVs to slot between its existing Ultra HD LCDs and super-colorful OLED models. These are different because they use quantum dot technology, which LG says will make for a wider color palette and better color saturation than regular LCDs. Sony's already using the technology in its high-end TVs, and reports have indicated that Samsung will offer LCDs with quantum dots as well. The tech used here will use nanocrystals in sizes of 2 to 10 nm that show a different color based on their size, laid in a film over the usual IPS LCD. LG has committed heavily to OLED as a display technology of the future, but even with prices dropping rapidly, it's still out of range for most buyers. As a result, improving traditional LCDs -- and trying to convince folks to upgrade to 4K at all -- is where the key battles will be. The new TVs will be available in 55- and 65-inch versions at first, and you can be sure we'll be taking a close look at them in Las Vegas next month.

How a mobile phone camera works visualized

How a mobile phone camera works visualized

Many people know how a camera works—at least conceptually. In the practice, it's not easy to imagine (in fact, it truly blows my mind if I really think of it.) This excellent 3D visualization shows exactly how the photo is taken. Very very neat.

Jaguar's 'Ghost Car' Navigation System Is Straight Up Science Fiction

Jaguar Ghost Car Navigation

Jaguar just unveiled a proposed new navigation system that's unlike anything we've ever seen.

Most modern navigation systems instruct drivers using a series of arrows or at best a pictographic representation of a highway exit. However, Jaguar's new experimental system abandons the arrows and instead projects an image of a "Ghost Car" for the driver to follow.

Officially known as "Follow-Me Ghost Car Navigation," the system uses the heads-up-display technology to project an illuminated "ghost car" that looks to be driving right in front of the actual vehicle. 

"Driving on city streets can be a stressful experience, but imagine being able to drive across town without having to look at road signs, or be distracted trying to locate a parking space as you drive by," said Jaguar Land Rover's director of research and technology, Dr. Wolfgang Epple, in a statement.

"We want to present all of this information on a Heads-Up Display in the driver's eye-line, so the driver doesn't have to seek it out for themselves and take their eyes off the road ahead."

Jaguar Land Rover Virtual Windshield Ghost Car

In addition to automotive apparition, the experimental navigation system also projects onto the windshield an array of strategic information for the driver to use — such as parking guidance, stop light duration, and geographic landmarks.

This new nav system is related to the company's 360 Virtual Urban Windscreen technology, which features an array of video displays mounted around the car's cabin that virtually eliminates driving blind spots around the vehicle. 

As with Jaguar's Virtual Windscreen, there isn'! t a set date for the system's debut in a production vehicle. But I wouldn't be surprised to see it in the next generation Jaguar XJL Portfolio or Range Rover Autobiography.

How would you change Lenovo's Thinkpad Helix (2013)?

Source: http://www.engadget.com/2014/12/14/hwyc-lenovo-helix/

Lenovo's first Yoga machine still stands as a watershed moment in laptop and tablet design, but what of one of its successors, the ThinkPad Helix? In addition to those first two modes, you could spin the Helix's display outward, enabling you to use the device as a free-standing drawing display. When we placed it front of our Dana Wollman, however, she found that the exciting form factor had some drawbacks. Like the fact that the 'Rip'n'Flip' design wasn't all that, not to mention the last-generation internals and the short battery life. Still, we imagine some of you might have taken a liking this piece of hardware, so why not hop over to our forum and tell us what you would have changed?
