It’s usually over in an instant, but when you capture macro footage of a match head igniting at 4, 000 frames per second, suddenly that almost instantaneous event becomes a fascinating look into the science of fire and ignition. And believe it or not, YouTuber UltraSlo had to throw an additional 2, 000 watts of light on this match head to capture this mesmerizing footage—that’s a lot of birthday candles. Read more…

A brouhaha over adware-laced Chrome extensions has forced Google to remove two from its store and possibly exposed a wider issue. According to the original developer of “Add to Feedly, ” the problems happened after he sold his plug-in — created in a few hours — to a party for a too-good-to-be-true “four-figure” sum. As detailed in a blog, he discovered that new code was injecting ads into every page browsed without approval, angering users and lowering its rating. The same thing happened with “Tweet This Page, ” another app that served up unwanted ads after being sold. Since other developers were also approached, there’s speculation that it could be a new type of scam: buying perfectly good extensions, altering them and then letting Google slip them to users via automatic updates. After it was contacted by the WSJ , Google pulled the renegade extensions, saying that recently altered terms of service prohibit them. However, that’s only because they didn’t ask user permission; there’s nothing to prevent apps from inserting such ads — something to keep in mind the next time you tweak Chrome.

Inspired by the hoverboard Michael J. Fox cruises around on in Back to the Future Part II , ex-IDEO’er Kyle Doerksen created the Onewheel. A self-balancing electric monowheel skateboard, the Onewheel seemingly replicates the feeling of riding around on a hoverboard (if not the form factor), and even a novice can purportedly pick up how to ride one in less than a minute; in addition to the self-balancing feature, riders can accelerate by leaning forward and slow down by leaning back, as with a Segway. The 25-pound device will do 12 m.p.h., with a range of four to six miles. Charging the lithium battery takes from 20 minutes to two hours, depending on what type of charger you use. And the monowheel design means that maintenance is a lot simpler than it would be for a bicycle: “There’s literally only one moving part—the wheel, ” writes Doerksen. “No gears, belts or chains to maintain.” And yes, the Onewheel is real, not just a concept; Doerksen and his team have it up on Kickstarter , where it’s already tripled its $100, 000 goal. Check out the video: (more…)

Most of us in Europe and North America try not think about how much we’re getting smoked by Asia in terms of internet speeds, but here’s another reminder: residents in South Korea will soon enjoy 300Mbps wireless on the nation’s largest carrier, SK Telecom . That follows on the heels of a similar effort by CSL in Hong Kong, which achieved the same speed by combining two 20MHz LTE bands. However, the Korean carrier is using so-called LTE-Advanced 3-band carrier aggregation tech, which combines one 20MHz and two 10MHz bands. Before residents there can download the proverbial 800MB movie in 22 seconds, though, the new format will have to be standardized globally and adopted by smartphone and chip makers, a process SK said is underway. While you’re mulling that, the carrier will actually be showcasing even better 450Mbps tech in February at Mobile World Congress — so enjoy your 75Mbps max LTE, citizens.
