| Fake jellyfish made from rat cells have a place in our hearts (video) Jul 23rd 2012, 18:59  There's a whole sea of jellyfish out there ready to sting indiscriminately. So, why do we keep trying to make them? Scientists from Harvard and Caltech have a pretty good reason for creating fake jellies -- they hope to mend broken hearts by adapting their 'pumping' style of movement. Much like our own vital organ, the creatures are a mass of muscle adept at shifting fluid, meaning the research has several medical applications, such as bioengineered pacemakers for busted tickers. In creating the Medusoids, the team used a silicon scaffold coated in functional rat cardiac tissue, copying the muscle layout of a real jellyfish as best they could. When immersed in salt water and treated to bursts of current, the cells contract and cause the silicon sheet to move in a way eerily similar to the real thing. Next step for the team? An autonomous version that can move and potentially feed without their influence, of course. And, after seeing the little swimmers in action, we've certainly got palpitations. See what we mean after the break.

We all dread the fickle beasts known as WiFi deadspots. Luckily, Netgear wants you to keep that comfy seat or maneuver around the homestead without losing that Breaking Badstream. The outfit has unveiled its WiFi Booster for Mobile that pairs up with your home or office router to increase network reach for smartphones, tablets, laptops and other mobile gadgets. Touting universal compatibility with your existing 2.4GHz wireless equipment, the add-on uses a strategically selected outlet in order to flex its muscle boosting 802.11 b/g/n signals. Once you've plugged the unit, a WPS connection is merely a button push away. Netgear didn't offer any details on what kind of range increase you can expect. However, you'll be able to pick one up sometime this summer for $40 if you could use the help.

The (Japan-only) phone's 4.3-inch OLED screen holds onto a middling qHD resolution, but Fujitsu says its "new AMOLED Plus technology" will apparently render in higher clarity than any of its preceding smartphone displays -- we'll wait to see it in action before coming to any conclusions. There's no word on who's behind the dual-core 1.5GHz processor, but Xi connectivity (how Japanese carrier NTT DoCoMo brands its LTE provision) makes a Qualcomm chipset likely. Fujitsu is also pushing the phone's 'human-centric' Android skin, like what we saw on its own quad-core slab). This involves a collection of UI tweaks to the base Android 4.0 OS, including Intellicolor, where the phone will sense the color of ambient light and tweak the display accordingly. The phone's 13.1-megapixel camera reaches an impressively high ISO level of 25600, running on Sony's back-illuminated Exmor R sensor, while Fujitsu's also channeled the ghost of the original Motorola Atrix, resurrecting a fingerprint unlock sensor. Other features worth mentioning include high-definition NOTTV compatibility, plus certified water and dust resistance. As is expected from the world of Japanese smartphones, there's a selection of colors too -- the T-02D will be available in Pink, Black and Blue from launch. Japan residents wondering exactly which company made the phone can try to get their head around the full release below.

News Corp is bringing its 18-month-old educational division to the fore by rebranding it Amplify and teaming up with AT&T to put tablets in the hands of students. The unit will focus on developing products and services tailored for classrooms, ranging from kindergarten through high school. And, at the center of that ecosystem, will be the Amplify Tablet (which, judging from the video below, appears to be a modified Galaxy Tab). Videos, encyclopedia entries, books and even remote tutoring apps will all be just a tap away. The tablets will get their first trial run in the US during the 2012-2013 school year. With the phone hacking scandal behind him, former New York City school chancellor Joel Klein (who headed up News Corp's internal investigation), is free to focus on getting Amplify rolling and into classrooms across the nation. Before you head off, make sure to watch the clip from AT&T after the break. Continue reading News Corp launches Amplify educational unit, with help from AT&T (video) Filed under: Misc.
