Just when you thought it was safe to go back in the water, an anonymous reader writes in with news about a giant robot jellyfish. As if there weren't enough real jellyfish around to trigger our thalassophobia, researchers at Virginia Tech have created Cryo -- an eight-armed autonomous robot that mimics jelly movement with the help of a flexible silicone hat. The man-sized jellybot altogether dwarfs previous efforts, hence the upgrade from small tank to swimming pool for mock field tests. And unlike the passively propelled bots we've seen recently, Cryo runs on batteries, with the researchers hoping to better replicate the energy-efficient nature of jelly movement to eventually increase Cryo's charge cycle to months instead of hours. That's also the reason these robotic jellyfish are getting bigger -- because the larger they are, the further they can go."

dcblogs writes "Virtualization, cloud services and software-as-a-service (SaaS) is making it much easier to shift IT infrastructure operations to service providers, and that is exactly what many users are doing. Of the new data center space being built in the U.S., service providers accounted for about 13% of it last year, but by 2017 they will be responsible for more than 30% of this new space, says IDC. 'We are definitely seeing a trend away from in-house data centers toward external data centers, external provisioning,' said Gartner analyst Jon Hardcastle. Among those planning for a transition is the University of Kentucky's CIO, who wants to reduce his data center footprint by half to two thirds. He expects in three to five years service provider pricing models 'will be very attractive to us and allow us to take most of our computing off of our data center.' IT managers says a big reason for the shift is IT pros don't want to work in data centers at small-to-mid size firms that can't offer them a career path. Hank Seader, managing principal of the Uptime Institute, said that it takes a 'certain set of legacy skills, a certain commitment to the less than glorious career fields to make data centers work, and it's hard to find people to do it.'"

First time accepted submitter markboyer writes "The Solar Impulse just landed at Moffett Field in Mountain View, California to announce a journey that will take it from San Francisco to New York without using a single drop of fuel. The 'Across America' tour will kick off this May when founders Bertrand Piccard and André Borschberg take off from San Francisco. From there the plane will visit four cities across the states before landing in New York."

First time accepted submitter szotz writes "The National Ignition Facility has one foot in national defense and another in the future of commercial energy generation. That makes understanding the basic justification for the facility, which boasts the world's most powerful laser system, more than a little tricky. This article in IEEE Spectrum looks at NIF's recent missed deadline, what scientists think it will take for the facility to live up to its middle name, and all of the controversy and uncertainty that comes from a project that aspires to jumpstart commercial fusion energy but that also does a lot of classified work. NIF's national defense work is often glossed over in the press. This article pulls in some more detail and, in some cases, some very serious criticism. Physicist Richard Garwin, one of the designers of the hydrogen bomb, doesn't mince words. When it comes to nuclear weapons, he says in the article, '[NIF] has no relevance at all to primaries. It doesn't do a good job of mimicking secondaries...it validates the codes in regions that are not relevant to nuclear weapons.'"

Nerval's Lobster writes "This week, Egypt caught three men in the process of severing an undersea fiber-optic cable. But Telecom Egypt executive manager Mohammed el-Nawawi told the private TV network CBC that the reason for the region's slowdowns was not the alleged saboteurs — it was damage previously caused by a ship. On March 22, cable provider Seacom reported a cut in its Mediterranean cable connecting Southern and Eastern Africa, the Middle East and Asia to Europe; it later suggested that the most likely cause of the incident was a ship anchor, and that traffic was being routed around the cut, through other providers. But repairs to the cable took longer than expected, with the Seacom CEO announcing March 23 that the physical capability to connect additional capacity to services in Europe was "neither adequate nor stable enough," and that it was competing with other providers. The repairs continued through March 27, after faults were found on the restoration system; that same day, Seacom denied that the outage could have been the work of the Egyptian divers, but said that the true cause won't be known for weeks. 'We think it is unlikely that the damage to our system was caused by sabotage,' the CEO wrote in a statement. 'The reasons for this are the specific location, distance from shore, much greater depth, the presence of a large anchored vessel on the fault site which appears to be the cause of the damage and other characteristics of the event.'"

A reader points out that there is a great new panorama made from shots from the Curiosity Rover. "Sweep your gaze around Gale Crater on Mars, where NASA's Curiosity rover is currently exploring, with this 4-billion-pixel panorama stitched together from 295 images. ...The entire image stretches 90,000 by 45,000 pixels and uses pictures taken by the rover's two MastCams. The best way to enjoy it is to go into fullscreen mode and slowly soak up the scenery — from the distant high edges of the crater to the enormous and looming Mount Sharp, the rover's eventual destination."

Hot on the heels of the Gtk+ 3.8 release comes GNOME 3.8. There are a few general UI improvements, but the highlight for many is the new Classic mode that replaces fallback. Instead of using code based on the old GNOME panel, Classic emulates the feel of GNOME 2 through Shell extensions (just like Linux Mint's Cinnamon interface). From the release notes: "Classic mode is a new feature for those people who prefer a more traditional desktop experience. Built entirely from GNOME 3 technologies, it adds a number of features such as an application menu, a places menu and a window switcher along the bottom of the screen. Each of these features can be used individually or in combination with other GNOME extensions."
