Martin Jetpack hits the 5,000 feet milestone, could come to market within 18 months (video)

OK, so the Martin Jetpack may not have gone into commercial production quite as soon as we'd anticipated, but there's still hope on the horizon. Over the weekend, Glenn Martin's flying machine successfully climbed some 5,000 feet above sea level, marking a new milestone in the 30-year, $12 million project. Remotely controlled by a tailing helicopter, the 250-pound craft used its two "superfans" to power itself skyward at about 800 feet per ~~second~~ minute, before safely parachuting back to Earth from a height of about 3,000 feet. As with its last test run, however, the Martin Jetpack was equipped not with a human being, but with a crash dummy. It may have been for the best, though, considering that the machine sustained some damage upon concluding the ten-minute flight. Nevertheless, Martin seems confident that yesterday's test "brings the future another step closer," and is hoping to deliver his brainchild to customers within the next 18 months -- plenty of time for us to hawk enough family heirlooms to afford that $86,000 price tag. Soar past the break for a video of the jetpack's big launch, or check out the source link for a more extensive interview with Martin and some background footage of his invention.

Scientist cooks up adjustable strength metals

As you may know, crafting a katana is a delicate process that involves carefully constructing a razor-sharp high-carbon edge around a soft shock-absorbent core. One day though, smiths and forging fires could be replaced by electrode-wielding mad-scientists, with the technology to selectively harden and soften metal at will. At least that's what we envisioned when we read about Jörg Weißmüller's breakthrough research in the field of nanomaterials. The German scientist discovered that by placing precious metals in acid he could create tiny ducts through corrosion. Once those channels are flooded with a conductive liquid, electrical currents can be used to harden the material and, if you change your mind about the brittle results, the effect can easily be reversed to make it soft again. The tech could eventually lead to self-healing vehicle armor or scratch-resistant cellphones -- but, really, we just want to zap our way to a high-quality samurai sword. Physorg

Compal's 'Ultra Mobile' Ultrabook eyes-on

Intel's already teased Compal's "Ultra Mobile" Ultrabook from afar, but when this Ivy Bridge laptop popped up on the show floor after the Computex keynote, we decided to give it a closer look. While this prototype isn't quite in the same league as ASUS' gorgeous UX21, do bear in mind that we're still looking at a relatively slim package for a 14- to 15-inch Core i7 rig. Also visible around the machine are a couple of USB 3.0 ports, an HDMI-out port, a LAN socket, and an SD card reader. Until we hear more about this Ultra Mobile, enjoy our eyes-on photos below.

Google announces new ways to discover apps on Android Market, more tools for developers

Android Market may have a lot going for it, but most would surely agree that it could use some improvement when it comes to discovering apps that you aren't specifically looking for. Thankfully, it seems Google has indeed been aware of those concerns, and it's now announced five new features that should go so some way towards improving things. Those include some newly revamped top app charts that promise to be "fresher" and country specific, a brand new Editors' Choice section that highlights apps chosen by Google, a new Top Developers feature that places a special icon next to the name of developers that make the grade (currently more than 150), improved related apps on individual app pages and, last but not least, a new trending apps section that shows the apps growing fastest in terms of daily installs. What's more, while all of those features are currently exclusive to the web-based version, Google says they're also "coming soon" to the Andr...
