GM's Ultium motors will power its next-generation EVs
GM, the company known for Corvettes and Sierra pickups, has embraced EVs as much as any US automaker. It already revealed plans for its Ultium batteries and now, ahead of the 2020 Bolt EV launch, is showing off its Ultium electric motors and drive units for its next-generation of electric cars and trucks.
EVs outsold manual transmission cars in the US last quarter
While electric vehicles have some way to go before they are as ubiquitous as gas-powered cars, demand is on the rise. So much so, that they outsold manual transmission vehicles in the US last quarter, according to data from research group J.D. Power.
DJI reveals ultra-low-latency goggles for drone racers
Drone racers just got a major viewing upgrade. Aerial imaging company DJI has launched its digital first person viewing (FPV) transmission system, which boasts the first low latency HD video transmission signal. This means a crystal clear display, minimal lag, anti-inference reliability and range of up to 2.5 miles.
$550 dock turns a smartphone into a medical lab
Smartphones can now be used as laboratory-grade medical testing devices thanks to new kit designed by the University of Illinois. The transmission-reflectance-intensity (TRI) analyzer attaches to a smartphone to examine blood, urine or saliva samples as reliably as large, expensive equipment, but costs just $550. The technology uses a high-performance spectrometer. First, a fluid sample is illuminated by the phone's internal white LED flash, then the light is collected in an optical fiber. The light is then guided through a diffraction grating into the phone's rear-facing camera, and a reading is provided on-screen.
The slow death of the manual transmission
I've never owned a car with an automatic transmission. From my 1969 Datsun 2000 roadster to the 2011 Mini Countryman S that currently sits in my garage, I've had a long line of vehicles that required more than just pressing on the accelerator and pointing it toward a destination. Yes, there were a few years when my wife had a Honda CR-V with an automatic transmission. But my cars have always required me to actually shift gears. I plan on continuing this tradition for as long as possible. But I know eventually I'll be forced to drive a car with my left leg sitting idle.
Unofficial BitTorrent app once again linked to Mac malware
The developers of Transmission can't catch a break. Just months after their BitTorrent app was linked to the first known instance of Mac ransomware, security researchers at ESET have pinpointed another form of malware taking advantage of Transmission to infect Mac users. Keydnap, as it's called, takes advantage of a modified version of Transmission (planted on the developer's site without its knowledge) to attack your computer. It's similar to the ransomware's approach in more ways than just its choice of host app -- it even uses a signing key to trick Apple's Gatekeeper safeguard into letting it through.
Sneezing is even more disgusting with high-speed cameras
New, super-gross research out of MIT is shedding new insights into what happens when we sneeze. Researchers from the university used high-speed photography to record 100 healthy volunteers right at the moment they sneezed. Turns out, the sticky fluid flies out of our mouths, not as a spray, but as a sheet. Ew. Then it pops, like a balloon, and the snotty filaments remaining then in turn break up into the fine mist we're familiar with. Double ew.
A guy in the UK called the ISS from his backyard and you can too
For most of us, visiting the International Space Station is little more than an impossible dream -- but if you know what you're doing, talking to the orbiting laboratory is surprisingly plausible. No, really: just ask Adrian Lane, a Gloucestershire UK Ham radio operator who called up an ISS astronaut from the comfort of his own backyard shed.
Researchers achieve world record in wireless data transmission, seek to provide rural broadband
Speed. It's a movie. It's a drug. And it's also something that throngs of internet users the world over cannot get enough of. Thankfully, the wizards at the Fraunhofer Institute for Applied Solid State Physics and the Karlsruhe Institute for Technology have figured out a way to satisfy the unsatisfiable, announcing this week a world record in the area of wireless data transmission. Researchers were able to achieve 40Gbit/sec at 240GHz over a distance of one kilometer, essentially matching the capacity of optical fiber... but, you know, without the actual tether. The goal here, of course, isn't to lower your ping times beyond where they are already; it's to give rural communities across the globe a decent shot at enjoying broadband. Distances of over one kilometer have already been covered by using a long range demonstrator, which the Karlsruhe Institute of Technology set up between two skyscrapers as part of the project "Millilink." There's no clear word on when the findings will be ported over to the commercial realm, but given the traction we're seeing in the white spaces arena, we doubt you'll have to wait long.
Rolls-Royce Wraith picks gears using GPS, keeps your Spirit of Ecstasy soaring (video)
Many Rolls-Royce drivers are used to effortless speed between the big engines and smooth suspensions. The automaker's new Wraith coupe could iron out what few of those wrinkles are left through a clever use of GPS for the transmission. Its eight-speed ZF automatic gearbox relies on positioning to pick gears in advance, gauging the situation down to the exact stretch of road: it can see the need for a shorter gear at the upcoming corner, for example. Other tech upgrades aren't quite as fresh, although we're sure that less traditionalist Rolls drivers won't mind a heads-up display, voice command support and the infotainment system's multi-touch trackpad. The Wraith's €245,000 ($318,745) price and late 2013 availability will likely be too much to endure if all you're looking for is seamless shifting -- they may, however, provide some consolation for missing out on that LaFerrari.
BBC shows off 33-megapixel Super Hi-Vision Olympic footage, we ask: why?
The first live Super Hi-Vision broadcast for public consumption was of the Olympic opening ceremony in London last week. We didn't get to see that premiere, or the second or third screenings either -- but the fourth? Oh yes. We grabbed a seat right up front of a small theater inside BBC Broadcasting House, watched a live 33-megapixel feed from the Aquatics Center and absorbed some very fond memories in the process. At the same time, a question hung over the footage like a watermark: why bother? The world is barely getting to grips with the notion of 4K, which already solves pixelation at regular viewing distances, so why did the BBC and Japanese broadcaster NHK go to the expense of sending a dedicated SHV video truck, a SHV audio truck rigged for 22.2 channel sound, and the world's only three 8K Ultra HDTV cameras to London? Fortunately, we caught up with someone in charge who was able to respond to that question. Read on for what they said, plus a slightly fuller sense of what the footage was like to watch.
Judge calls Samsung vs. Apple 3G suit 'ridiculous,' suggests mediation instead
Annabelle Bennett is no stranger to Apple/Samsung litigation -- the Federal Court of Australia judge has had a hand in the companies' disputes for at least the past year. And it would appear that she's grown a bit impatient, following a Samsung move that she's labeled as "just ridiculous." According to a Bloomberg report, the trial began with Samsung's attorney stating that Apple refused to pay a fee to license three patents related to 3G data transmission. Apple's counsel, however, explained that the company did offer to pay, but Samsung refused. Bennett responded by asking "why on earth are these proceedings going ahead?," following up with "why shouldn't I order the parties to mediation?" -- a question she expects to be addressed by the end of the week. There doesn't appear to be any official ruling at this point, though the trial certainly isn't off to a great start for Samsung. Ultimately, the duo may be forced back to the negotiating table, letting Bennett move on to other cases until the next patent rouse.
4K TV already being trialed by one UK broadcaster
4K in the UK? It could happen sooner rather than later, if viewers give a thumbs up to feedback tests currently being conducted by a British broadcaster. According to a senior figure at a company that is directly involved in the experiments, people are being asked if they can spot the difference between 4K and regular 1920 x 1080, which will help to decide whether the format is worthy of immediate investment. Our source refused to reveal which broadcaster is running the show, beyond saying that it has complete control over its pipeline right down to the set-top box, which hints at Sky or perhaps Virgin being likely candidates. When asked how 4K TV might be transmitted as a mainstream service, given that it contains four times the resolution of Full HD, he simply replied that the broadcaster would "compress the hell out of it," which surely only cements his credibility. Next stop, 8K.
A day in the life of a Gmail email
Electronic mail, or email to those in the know, has become so ubiquitous and transparent that many take for granted the effort and engineering required to make this near-instant communication medium a reality. In an effort to remind the general public about this digital miracle, Google (a company that knows a thing or two about the subject) has launched a new mini-site dubbed The Story of Send. The web novella leverages animations and videos to explain what happens to a Gmail dispatch once it's jettisoned from your mail client of choice. Message transmission, data security and green computing initiatives are just a few of the topics on the menu. Saunter past the break, have a peek at the video primer then make sure to check out the full Story of Send site.
Phi: a wireless re-routing card that puts you in control of the airwaves (video)
For all the talk of convergence in mobile devices, there's relatively little chatter about the coming together of wireless signals themselves. In other words, why should we have a separate device to interact with each type of wireless signal? And so, with that intriguing question, begins the pitch for a new device call Phi. It's a $750 antennae-laden PCIe card that slots into a desktop and gathers up wireless signals that are flying around the home -- so long as they have a frequency below 4GHz and don't involve bank-busting neutrinos. The card then allows custom apps to re-direct those transmissions as you like: potentially acting as a "base station" so you can make free calls from your cell phone, or receiving over-the-air HD transmissions which you can play on your tablet, or doing whatever else hobbyists and devs can cook up. Phi is still version 0.1 and Linux-only while the startup behind it -- Per Vices -- looks for a Kinect-style blossoming of third-party interest, but with nothing less than a deity-like command over the domestic ether on offer, how could it ever fail?
Brammo's 100MPH Empulse coming May 8th, spooks electrons with six-speed gearbox
By rights, Brammo's street-fighting Empulse should have gotten here quicker, but at least we now have a firm launch date. Sporting an all-new six-speed gearbox in place of the one-speed original, Brammo's spec sheet shows a 121-mile city range (or 56 miles on the highway), 100+ MPH maximum hustle and a re-juicing time of 3.5 hours in fast-charge mode. We're not sure if the price has budged from the original $14,000 estimate, but if you want to see what that ballpark sum might get you, the video after the break is all yours.
Guide to transmogrification resources
You just spent 13,000 gold on a pair of purple boots. No, not purple quality -- purple as in the color. What? It matched the subtle detailing on your tier 2 shoulders perfectly. OK, maybe not perfectly, but it's close enough. Wait, maybe you can find something closer? Better go look again. We get it. You're addicted to transmogrification. Your void storage is packed full of gear that you haven't worn since level 9, and your friends are planning to stage an intervention. You want more -- no, you need more. Fortunately, we're here to help. Like a best friend who brings you a batch of her famous marshmallow chocolate chunk cookies two days after you start a diet, we've compiled a list of transmogrification resources you may find useful in getting your next fix -- I mean, outfit.
New undersea cables planned for arctic passageways, frozen gamers dream of lower pings
Hot on the heels of our own reporting of cables in the South Pacific (or the lack thereof), in flies a report that at least two new undersea cables are being planned for the arctic. According to New Scientist, a pair of lengthy fiber optic wires will be laid through the Northwest Passage above North America, connecting Japan to the United Kingdom. Moreover, a third cable is planned along the Russian coastline, with the longest of these links to purportedly become "the world's longest single stretch of optical fiber." A number of outfits are on the list to help out, and when complete, the latency between Tokyo and London should be reduced between 168ms and 230ms. The cost for such luxury? An estimated $600 million to $1.5 billion for each line. In other words, totally worth it.
Neutrinos can transmit messages through walls, mountains, planets
Neutrinos may not travel as fast as we first hoped, but then they have other special abilities to make up for it. Being almost massless, they can penetrate the thickest barriers, which ought to make them ideal message carriers. To illustrate the point, scientists sent the word "Neutrino" on a beam of particles through 240 meters (800 feet) of solid stone and received it loud and clear on the other side. The same approach could potentially be used to send a message right through the center of a planet, making it possible, according to one of the researchers, to "communicate between any two points on Earth without using satellites or cables." The experiment required the latest particle accelerators at Chicago's Fermilab, which flung the neutrinos over a 2.5 mile track before firing them off at an underground receiver, but it proved the principle: Shrink the accelerator down to the size of a smartphone and neutrino messaging could be huge. Or it could die in a format war with quantum teleportation.
Terahertz bandwidth: the key to 1,000x faster smartphones, laptops and pipe dreams
Much like carbon nanotubes and quantum computing, terahertz technologies have been promising miracles for nearly as long as humans have been able to distinguish water from fire. We exaggerate, but barely. A crafty team assembled at the University of Pittsburgh seems to have no qualms with moving forward, however, recently announcing a new physical basis for terahertz bandwidth. Those involved managed to have success in generating a frequency comb -- "dividing a single color of light into a series of evenly spaced spectral lines for a variety of uses -- that spans a more than 100 terahertz bandwidth by exciting a coherent collective of atomic motions in a semiconductor silicon crystal." For those who managed to make it through the technobabble, we're told that the ability to modulate light with such a bandwidth could "increase the amount of information carried by more than 1,000 times when compared to the volume carried with today's technologies." Smartphones, computers and even airline check-in kiosks that operate 1,000 faster than they do today? Sure, we'll take that. But, how about give us a ring when Wally World deems it ripe for commercialization? We'll be waiting -- pinky promise.
