Submission + - Navy Demonstrates Laser Weapon, Disables Target (ibtimes.com)

RedEaredSlider writes: The Office of Naval Research has made a significant step in laser-based military defense this week.

The Navy announced that it tested a solid-state, high-energy laser (HEL) from a surface ship, which disabled a small target ship close by. The Navy tested the Maritime Laser Demonstrator (MLD) with a partner private contractor, Northrop Grumman. The laser validated the potential for advanced self-defense for surface ships and personnel by keeping small boat threats at a safe distance.

Submission + - Fukushima: What happened and what needs to be done (bbc.co.uk)

IndigoDarkwolf writes: The sometimes confused media coverage around the Fukushima Daiichi nuclear plant left me wont for a good summary. Apparently the BBC felt the same way, and delivers with an overview starting from the earthquake and concluding with the current state of the troubled reactors.

Submission + - Panasonic's 100GB Blu-Ray arrives (pcauthority.com.au)

An anonymous reader writes: It's not unusual to hear of advances made in some research laboratory that could one day lead to unheard of advances in disc storage, like 1000GB optical media. But it's not so often that we see one of these mutant discs — costing a reported 10,000 yen, or approximately $112 — go on sale. Panasonic's BDXL Blu-Ray discs are re-writable and capable of storing 100GB, thanks to three storage layers. According to this story, it can take more than one and a half hours to fill a disc with a compatible drive.

Submission + - IBM Nanoparticle Breakthrough Destroys Drug-Resist (business2press.com)

ext99 writes: "IBM developed new ground breaking (yes, ground breaking actually means something here) nanoparticle technology that searches and destroys drug-resistant bacteria that cause millions of deaths from serious infections. The technology uses biodegradable plastic “to engineer electrically charged nanoparticles that in turn attract to the bacteria’s opposite charge, in turn destroying the membrane walls hence the cell entirely.” “The system proved successful in destroying methicillin-resistant staphylococcus aureus (MRSA) bacteria in laboratory tests involving infected mice,” but has yet to be tested on humans. IBM is in talks with major pharmaceutical firms to develop a clinical trial. Very promising technology, hopefully it could be adapted to work against other serious drug-resistant diseases."

Inventor Creates Flotation Device Bazooka 144

Australian inventor Sam Adeloju has won the £20,000 ($32,000) James Dyson Award for inventing the coolest piece of life-saving equipment ever. The Longreach is a modified bazooka which can fire an expanding flotation device up to 150m to a person in distress. From the article: "Mr Adeloju told NEWS.com.au that the Longreach was inspired by a grenade-launch training session with the Army Reserves. Weighing just 3.5kg, it shoots the rescue device 150m in a manner similar to the way the army uses a grenade launcher to deliver flares and aerial observation devices. Hitting the water activates an expanding foam unit in the Longreach rescue unit, which also incorporates LED illumination and a vortex air whistle."

Man Serves Fried Beer 9

wenaway writes "Mark Zable, creator of Fried Beer, brought his creation to the State Fair in Texas. He walked away from the fair with the most creative award and is now gearing up for larger production. The Fried Beer is actually a pretzel dough ravioli injected with beer and then deep fried to perfection. What's next? Fried booze."

Lasers Approach Their Ultimate Intensity Limit 384

Flash Modin writes "Death Star style superlasers? Don't bet on it. High-power lasers currently in development appear to be nearing the theoretical laser intensity limit, according to new research set to be published in the journal Physical Review Letters. Ultra-high-energy laser fields can actually convert their light into matter as shown in the late '90s at the Stanford Linear Accelerator (SLAC). This process creates an 'avalanche-like electromagnetic cascade' (also known as sparking the vacuum) capable of destroying a laser field. Physicists thought it might be a problem for lasers eventually, but this work indicates the technology is much closer to its limit than researchers believed. A preprint is available here."

Submission + - Seagate Hints To 100 TB Hard Drives (conceivablytech.com)

An anonymous reader writes: Are we running out of storage space? You may not have noticed it, but the current hard drive recording technology is in the second half of its life and a new technology will be introduced within 3 to 5 years. Seagate says that this technology will be heat assisted recording (HAMR) and it will enable 50x greater storage densities than the current perpendicular recording technology, which would be 300-500x the density of the previous linear recording. With PMR hard drives topping out at about 5-6TB in 3.5” drives, HAMR will take HDD manufacturers well beyond 100 TB.

David Pogue Gushes Over the Chumby 134

stoolpigeon writes "IHT is running a David Pogue review of the Chumby. The Chumby is a small computer embedded in a soft case. The Chumby hardware and OS are open, and the review mentions that the device already has a large developer following, cranking out new widgets for owners. Pogue is obviously quite taken with the Chumby and gives a good introduction to a device that may be the inspiration for a new generation of hackers."
It's funny.  Laugh.

Free (As In Speech) Beer, V2.0 266

AgentPaper writes "Three years ago we discussed an open source brewing project in which a Danish brewer made his beer recipes available for public consumption and alteration. The concept has taken off, first with the 'Free Beer Project' in Denmark and now with Flying Dog's 'Collaborator' Doppelbock in the US, which was created via input from home brewers across the world. One version of the Collaborator is commercially brewed and available for purchase (and is darned tasty), but you can download the same recipe and labels, brew it yourself, and submit your mods back to the project."

DataStorm V1.0, a Full-Auto Floppy Disk Cannon 153

Bob Loblaw writes "I ran across a huge stash of floppies at our office, and after some discussion, it became clear that rather than throw them away, we should build a gun that fires floppies. I had just bought a welder so this was a challenging first project. After about a month of work in my garage at night the DataStorm was born. It was constructed of scrap metal, a kid's bike, a weed-eater motor, and an electric screwdriver. The most difficult task ended up being how to add spin to the disk without significantly reducing its velocity. After a week and a half of trying different options, a stack of zip ties was found to work best. Since we had so much time in it we elected to shoot an infomercial showcasing the device, and had to learn to shoot & edit video as we went. It was basically an office joke that spiraled out of control. My wife is not amused. At all. I hope you like it."
