Researchers Create Chemically Powered Robotic Jellyfish

pigrabbitbear writes with an excerpt from an article at Motherboard: “Earlier last week we heard about the strange blob-bot, an amoeba-mimicking, pulsating, little horror of a robot. But that’s nothing in the face of news that engineers at Virginia Tech have built a robotic jellyfish. As if the threat of the oceans being taken over by deadly stinging jelly cyborgs isn’t scary enough, there’s this: the researchers claim that, because their Robojelly is powered by a hydrogen-based catalytic reaction, rather than electricity, it could ‘theoretically’ power itself indefinitely. When you consider our best options for powering underwater craft are currently batteries, nuclear reactors, or tethers to the surface, a chemically-powered propulsion system is groundbreaking (and, well, a bit nerve-wracking).”

The 18 Games That Actually Use the iPad’s Fancy New Screen [Ipad]

The new iPad is faster than its predecessor, sure, but the main selling point is its glorious retina display. Problem is, nearly every game on the App Store was designed for the previous models, meaning they’re not exactly making the most of that 2048 x 1536 resolution. More »

Ever wondered how much the interwebs contribute to the Uncle Sam’s bottom line? Thanks to the Boston Consulting Group, now you don’t have to, as it’s estimated the net contributes a cool $684 billion is to the US gross domestic product. That’s roughly 4.7 percent of US GDP, the same tranche as its effect on Japan’s economy, but less than the 5.5, 7.3 and 8.3 percentages clocked in by China, South Korea and the United Kingdom, respectively. And per the report, the internet is just getting started, with future growth set to hit eight percent on average by 2016 for developed countries, and well north of 20 percent in booming economies like those of Argentina and India. Hit the source for the full report.

FreedomPop’s New iPhone Case Promises Users Free Wireless Data

FPcase

Skype founder Niklas Zennstrom’s new FreedomPop project was initially shrouded in secrecy, but they’ve recently become a bit more talkative about how the company plans to offer “free wireless broadband” to their customers.

FreedomPop CMO Tony Miller spilled the beans about the company’s WiMax-based freemium wireless data service to Forbes, but left yet another question unanswered — what’s the “innovative” new wireless device they’ve got in the works?

Well, according to a high-level source inside FreedomPop, it’s an iPhone 4/4S case… with an integrated WiMax radio. Think of it as a mobile hotspot squeezed into a case — I’m told that it’ll run for up to 30 hours, and can share its Internet connection with up to eight devices (including the iPhone that it’s attached).

As I understand it, each FreedomPop iPhone case user will have free access to a 1GB data plan right off the bat. That’s the only plan that FreedomPop will offer for the sleeve, though their overage fees seem strangely familiar: each MB over the limit will cost a penny, which means every gigabyte over the limit is $10. That’s not to say that FreedomPop users can ditch their carriers entirely — the case alone isn’t enough to let users place voice calls, and major carriers generally won’t let you buy a smartphone without a data plan to go with it.

There are still some costs involved though, specifically a deposit that each user has to shell out for a WiMax-friendly iPhone case of their own. My source tells me that the deposit will be under $100, and will be fully refundable to customers if they ever choose to discontinue their service so long as the sleeve is still in good condition.

Users will also be running on ClearWire’s 4G network, and while that isn’t as fast as AT&T or Verizon LTE, it’s often more than enough to give 3G networks a run for their money (depending on their location, anyway). Their reliance on ClearWire could prove to be a bit of a stumbling block since it doesn’t have the biggest footprint, but FreedomPop is currently in talks with other “major” wireless providers about the possibility of branching out.

FreedomPop isn’t doing this out of the goodness of their hearts — they’re obviously in it for some cold, hard cash. Their plan is to make money off of a slew of value-added services they intend to roll out in coming months — it’s their hope that they’ll be able to convert 10-15% of their free users into paying customers, which will subsidize the service for everyone else. Whether or not that actually pans out is another question entirely, but we’ll have to wait and see how much momentum FreedomPop will be able to build first.

As far as how innovative this thing is, well, that’s debatable. It’s a concept that we’ve seen pop up a few times in the past, perhaps most notably when Sprint started offering the ZTE Peel, an add-on for the iPod Touch that gave the device a persistent wireless Internet connection. But hey, free Internet thanks to some low-cost, low-risk hardware? Giddy up.

Einstein’s papers digitized

Emcccc

The Hebrew University of Jerusalem is scanning and posting more than 80,000 documents from the University’s Einstein Archives and the Einstein Papers Project at Caltech. Seen above is a snip from a manuscript titled “E=mc2: The Most Urgent Problem of our Time,” published in a 1946 issue of Science Illustrated. The paper is only one of three handwritten documents containing the formula. Einstein Archives Online

How to create an iPad archive of the entire run of Spy magazine in two hours

201203200822

Using an OS X utility called Google Book Downloader, Andrew Hearst downloaded every issue of the late Spy magazine into his dropbox account, giving him a tablet-ready version of the fantastically funny and much-missed magazine that poked fun at infamous assholes.

Scrolling through the pages of Spy in Google Books using a desktop or laptop web browser isn’t a great reading experience. Luckily, there’s a much better option: Using a Mac desktop app called Google Book Downloader, you can scrape Google Books to create PDFs of many of the publications and books in Google’s archive. (I’m sure there must be Windows apps that do the same thing.)

On a recent weekend afternoon, I used Google Book Downloaderto generate a PDF of every issue from Spy’s heyday, then pulled everything into my Dropbox account to allow me to access the archive from anywhere and any device — primarily my iPad. The whole process took me less than two hours. The filesize of the PDFs ranges from about 25 megabytes to about 50 megabytes, and the quality is quite high; the issues look fantastic on my new iPad’s retina screen. An iPad gives a much better approximation of an actual print-magazine experience than a web browser does, and if you save an issue into a PDF-friendly interface like Amazon’s Kindle app, you can use page thumbnails to navigate. It’s pretty sweet.

You can use Google Book Downloader with other magazines, too. Try Popular Science, August 1927, or Baseball Digest, September 1966, to name just two at random…

Visualized: new iPad burns 10 degrees hotter than its predecessor

We wouldn’t exactly be going out on a limb by suggesting that the new iPad is Apple’s hottest tablet to date — even before Tim Cook confirmed as much earlier today. But while Apple has plenty of reason to brag about the device’s sales figures, it’s slightly less motivated to be forthcoming about its tendencies to create more heat. 10 degrees more, in fact, according to infrared camera confirmation obtained by Tweakers.net. After five minutes of running GLBenchmark, the site used its infrared cam to confirm what many of you have already suggested: the new iPad runs a little hot. According to the site’s measurements, Cupertino’s flagship slab reached 33.6 degrees centigrade (92.5 Fahrenheit), compared to 28.3 centigrade (82.9 Fahrenheit) with the iPad 2. That’s certainly not enough heat to cause a tablet to spontaneously combust, but if you happen to be one of those new iPad owners that noticed a difference, you can now rest assured that your internal thermometer hasn’t missed a beat.

Seagate hits one terabit per square inch, compares self favorably to the Milky Way

You know that big new hard drive you just picked up? Get ready to feel bad. Seagate today is talking up the fact that it has managed to cram one terabit (that’s one trillion bits, for the record) into a square inch. That super-dense storage comes thanks to heat-assisted magnetic recording (HAMR) technology, a successor to the perpendicular magnetic recording (PMR) being utilized in current hard drives. The manufacturer sees the technology hitting the market later this decade, “doubl[ing] the storage capacity of today’s hard drives” in its wake. Just how many bits are we talking about here? Let Seagate put things into astronomical perspective: “The bits within a square inch of disk space, at the new milestone, far outnumber stars in the Milky Way, which astronomers put between 200 billion and 400 billion.” More info can be found in the press release after the break.
