eBay has just posted a strange message up on the community homepage and press page of its daughter company, PayPal. The headline is a bit worrying, implying that eBay has possibly had some kind of security or maintenance problem, leading it to request all users to change their passwords. On the other hand, the body of the post is empty except for the words “placeholder text, ” and nothing has yet been published on eBay’s own site. We’ve contacted eBay’s press office to find out what (if anything) is going down, but in the meantime it might be worth changing those passwords, just in case. Update : We haven’t heard anything back, but eBay’s website people seem to be in the process of removing the password message. It’s gone from the community page and is now only visible on the press site, so it’s looking increasingly likely that it was posted in error. Filed under: Internet Comments Source: PayPal

eBay wants all users to change their passwords

Scientists at the Cockrell School of Engineering in Texas have created a nanomotor less than one micrometer in diameter, smaller even than a cell. Powered by electric fields, it consists of a nanowire , magnet and electrode and can spin at a terrifying-sounding 18, 000 RPM for over 15 hours (see video below). That’s as fast as a jet engine, but don’t worry (much). During testing, it showed the ability to pump fluids at hyper-fast speeds and to move around freely in other liquids. That opens up beneficial applications like highly controlled insulin delivery, or devices that could specifically target malignant cells. Of course, that would mean you’d have to let intelligent nano-devices with mini-saws roam about your body — I guess you’re allowed to be a bit terrified.

Verizon and AT&T, the two largest mobile operators in the US, have spent the last couple years in a race to deploy next-generation voice technology known as Voice over LTE (VoLTE). With its announcement last week, AT&T was the first to deploy the fast-speed VoIP network, but don’t count Verizon out of the race quite just yet: executives explained to us today that it’s still on track for nationwide deployment sometime this year. Considering AT&T launched VoLTE last week, it appears that Verizon may be experiencing a few setbacks. (Of course, Verizon originally promised its network would be ready by 2012, so we’d argue that setbacks are nothing new for VoLTE deployment.) However, execs pointed out that its competitor’s offering is currently limited to just a few markets and devices, whereas Verizon will launch VoLTE nationwide from the very beginning. Nationwide availability will be crucial to the network’s success, as calls using the new tech can’t fall back to CDMA when you leave LTE coverage. Unfortunately, the company won’t say specifically when this year we can expect the new network, but we were told that when it’s ready, several devices will be VoLTE-capable either through purchase or an over-the-air update. Fortunately, Verizon confirmed that its network will be interoperable with any of its VoLTE-capable competitors — since you’ll only be able to enjoy richer call quality when both callers have compatible devices, this means the service won’t be exclusive to in-network conversations. The company also tells us that it will offer FaceTime-like video calling as soon as VoLTE launches, which means that you’ll be able to activate the service directly from your phone’s dialer, and you’ll be able to easily switch back and forth between video and audio-only calls. Additionally, it’ll also launch HD Voice by leveraging AMR-WB, a wide-band speech standard that’s already used by T-Mobile for its high-def voice service .

No, that’s not a detached tank tread you’re looking at, it’s a treadmill — and it doesn’t care which direction you’re walking. It’s called the Infinadeck, and we found it hiding in a dark corner of the Silicon Valley Virtual Reality Expo. Each of its tank-like treads is covered in a moving belt which, when used in tandem, gives the user the ability to stroll in any direction. The omni-directional treadmill has apparently caught the attention of CBS too, as a possible prop for filming on green-screen sets, but it isn’t ready: the prototype still requires an active operator to change directions. It’s also quite loud. Infinadeck says its trying to secure funding to build a more compact version with motion sensors, which should automate the process. Want to see how it works? Skip on past the break, videos await. Filed under: Misc Comments

The Lightning LS-218 boasts a model number that actually means something. Back in 2012, a prototype of the electric bike clocked in a wholly unnecessary (yet much appreciated) 218mph, helping it to win at Pikes Peak and setting it up to become the world’s fastest production motorcycle. The finished version is now ready to make good on that promise, having just been revealed at the Quail Motorsport Gathering in California, prior to a scheduled launch in the summer — at which point it’ll likely cost upwards of $38, 000. The bike has a much sharper look now, but the key specs are just the same, including a liquid-cooled 200-horsepower motor and a max range of 180 miles, depending on which battery option you choose. The weight of the battery causes it to be a heavy ride (225kg / 495 pounds) compared to some gas-powered superbikes out there, but what makes the Lightning stand out is the incredible torque (168 ft-lb) delivered by its gearless, direct drive internals. If you want to get a taste of what that feels like while blowing past someone on the highway, check out the video below at 3:10 — you’ll see a white sedan disappear into the background so quickly that you can barely identify the make.
