Combine that with the fact that high-end Predator pilots are severely fatigued from round-the-clock duty, and you can see why the DoD is making this move. It would expand the fleet of armed UAVs and make them cheaper to operate overall. Sure, the thought of 18 or 19 year old pilots fresh out of basic behind the controls of these machines is a bit unsettling—but it's not like this would be the first time the US threw a teenager into battle. Plus, we are taking about unmanned vehicles looking for specific, high-value targets. There is probably less chance of major incidents involving friendly fire or civilian casualties.

The audit also uncovered that the most significant of these lapses involved the DoD's handling of London-based weapons maker BAE Systems. According to the report, DSS failed to collect the company's internal audits—information that is crucial to determining potential weaknesses at the plant. The DSS responded saying that they have "a thorough and fundamentally sound facility inspection process which was only marginally diminished by the failure to systematically collect, analyze, and retain BAE's required reports" and that they have "taken action to resolve this shortcoming." However, a recent House Armed Services Committee hearing revealed that the DSS has been significantly understaffed for some time. Currently, around 750 people work for DSS and a rep claimed to be short staffed by "well over a hundred" persons.

So rest easy folks. Once again, you can be secure in the knowledge that our government has everything under control. UPDATE: BAE systems has responded to claims that their facility is not secure stating that "there is no basis whatsoever for that conclusion." [Wired]

Ten defense systems, to the tune of $100 million in products over the next four years, use P.A. Semi's PWRficient processor. On Monday, P.A. Semi told its customers they were being acquired and couldn't guarantee chip supplies anymore. (Brings us back to the problem of obsolete tech in the military.)

It's possible the licensing issues could get worked out to maintain supply "on an end-of-life basis" but in that same statement, P.A. noted that their buyer (Apple) wasn't interested in their products or roadmap, just their IP and engineering skills. Which means Apple has no interest in anything their currently making or about to make, despite Blam's reasonable assumption that was the case. So it's all about their design chops, or they really are just a bargaining chip. [EETimes via GigaOM]

The proposal is for the bat to be just six inches in length, weigh only four ounces and use just one watt of power, backed by a lithium-ion battery, which could be charged by not just solar energy, but wind energy and random vibrations as well. The bat's intended goal would be to run surveillance ops and relay data in realtime, including sights and sounds from minicams and mini-microphones, but also radiation and poison gas readings.

The UMich grant consists of $10 million over five years, creating the U-M Center for Objective Microelectronics and Biomimetic Advanced Technology (dubbed "COM-BAT"—pun intended). The focus is to shrink down many electronics that while currently available would only be good if the US Army wanted, say, a 12-foot spy-bat. Not too stealthy.

For energy recovery, UMich will work to develop "quantum dot solar cells," making current solar cells twice as nice. The bat's autonomous navi system will be 1,000 times smaller than current systems, and that much more energy efficient too. The comms system will be shrunk to one-tenth the current size, too. You can see how all of this shrinkage will have positive impact outside the bionic-bat community as well. [UMich via Ubergizmo]

The key characteristic of the femtosecond laser is the fact that it uniquely can hit its target without burning anything in the surrounding areas. According to Robert Tzou, head researcher and chairman of the department of Mechanical and Aerospace Engineering, this could mean the end of nasty chemotherapy:

"If we have a way to use the lasers to kill cancer cells without even touching the surrounding healthy cells, that is a tremendous benefit to the patient. Basically, the patient leaves the clinic immediately after treatment with no side effects or damage. The high precision and high efficiency of the UUL allows for immediate results."

"With the laser, we can melt a very thin strip around titanium micro- and nanoparticles and ultimately control the porosity of the bridge connecting the bone and the alloy. The procedure allows the particles to bond strongly, conforming to the two different surfaces."

Here are the technical requirements:

The complete power system must weigh 4kg or less and provide a minimum of 1920Whr. The power system must operate continuously for 96 hours. During the 96 hours of operation the system must operate: (1) continuously (i.e., 24 hours a day); (2) at partial power; (3) for a number of periods of high power of up to 200W for 5 min; (4) in a non-air breathing mode in a sealed container for a time to be determined; (5) be attitude or vertical orientation and motion independent; (6) provide output voltages of 14V and 28V. The system must attach to a vest and operate while worn. The government will provide connectors for the equipment on the course with additional cables, outlets, etc.
