Blazingly fast lasers have just leveled up. Ultrafast lasers emit short, rapid-fire bursts of light, with each pulse typically lasting tens of millionths of a billionth of a second. A new laser pulses 30 billion times a second — about 100 times as fast as most ultrafast lasers, researchers report in the Sept. 28 Science. The speed boost was thanks to a new technique for making ultrafast lasers. Typically, researchers use a technique called mode locking, in which light bounces back and forth in a mirrored cavity in such a way that the light waves build on each other to create short flashes. The new method takes a more “brute force” approach, says study coauthor David Carlson, a physicist at the National Institute of Standards and Technology in Boulder, Colo., by essentially carving up a continuous laser beam into individual pulses. Ultrafast lasers can produce what’s known as a frequency comb, light made up of discrete colors. Those evenly spaced hues look like … [Read more...] about A new ultrafast laser emits pulses of light 30 billion times a second

Early 2017's HTC U Ultra and U Play were a pair of devices designed to usher the Taiwanese giant into a new era of smartphones. For a number of reasons, however, consumers weren't really happy with this new direction, so up until now HTC was in need of a new hit. Enter the HTC U11 – a solid flagship with a number of unique features, it might just prove to be exactly what HTC needs right now.At a cursory glance, the U11 looks to be an amalgamation of its predecessor, the HTC 10, and its siblings in the U line, a theory proven right by its peculiar name, seemingly specifically chosen to underscore the device's origins. But look under the surface, and you'll find an entirely new type of user interaction, called Edge Sense, which lets you squeeze the device to perform context-sensitive actions.But more on that in a bit; first, let's take a look at the HTC U11's specs:PlatformAndroid 7.1 NougatDimensions, Weight 153.9 x 75.9 x 7.9 mm, 169 gDisplay5.5 inch, Quad HD Super LCD 5 … [Read more...] about The HTC U11 is the company’s new flagship, and you can squeeze it!

The Xperia XZ and X Compact share the same enhanced 23 MP camera sensor that promises blur-free and color-accurate photos, thanks to the new Laser AF system, and the RGBC-IR color sensor. They also offer 5-axis digital image stabilization during video sessions for the first time in a phone, as well as plenty of manual controls like exposure, shutter speed, or focus points...

Last month, Pebble introduced its latest smartwatch designs as it began the crowdfunding effort for the Pebble 2 and Pebble Time 2. Neither strayed too far from what worked for their predecessors, while delivering upgrades like faster processors, a larger screen, stylish new looks, and heart-rate monitoring hardware. And while that was all well and good, we could understand how the news could be a bit of a letdown for fans of Pebble's circular-screened Pebble Time Round; where was their new model? While Pebble's still not ready to reinvent that hardware for a full-on Pebble Time Round 2, today we do get word of a couple new finish options that are on their way, as Pebble reveals new shiny metallic polished gold and polished silver colors.As you may be aware, the Pebble Time Round has already been available in both silver and rose gold colors. The difference here is that these new polished options add some extra shine to their looks, and we pick up a classic yellow-gold shade (if pink's … [Read more...] about Pebble Time Round picks up new polished gold and silver color options
The LG G3 has arrived, ushering us into the era of Quad HD (1440 x 2560-pixel) displays on our smartphones, but there are just so many new things about LG's 2014 flagship, that you might feel a bit overwhelmed.

Indeed, the G3 seems like a huge evolution over last year's G2. Best of all, though, LG listened to user's criticisms and reacted.
