From what I hear (from documentaries, reality TV shows), prison ain't nothin' nice. I don't mean just for the prisoners, but for the guards as well. Not a job I envy in the least, but one that obviously is necessary. Sometimes a person just decides to hurt himself or another and prison guards need tools to deal with this. Assault weapons are necessary in some situations, but sometimes knowing a lot about what you're getting into can be useful.

Internal bleeding can cause irreversible haemorrhagic shock within 30 seconds or progressive shock within eight hours, either way, it's not good and the military wants a portable, noninvasive way to detect and stop it right on the battlefield.

To that end, the Defense Advance Research Projects Agency (DARPA) has contracted with Siemens Healthcare, the University of Washington's Centre for Industrial and Medical Ultrasound and Texas A&M to develop something called the Deep Bleeder Acoustic Coagulation cuff (DBAC). The cuff is a semi-automated, ultrasound device designed to cut blood loss and shock resulting from combat limb injuries, … Read more

The U.S. Air Force has awarded Boeing a new contract worth up to $30 million for the next phase of development on the Advanced Tactical Laser.

The ATL is a C-130H aircraft outfitted with a 12,000-pound high-energy chemical laser module that would be used as a weapon against ground targets. It's the smaller sibling of the Airborne Laser, a highly modified 747 under development that packs a similar weapon but that would be used against ballistic missiles.

While the 747-centric ABL is designed to fire its laser through a bulbous nose apparatus, the ATL totes a belly turret reminiscent of the manned versions used in some World War II bombers.

The new Extended User Evaluation contract marks the start of a transition for the ATL, which Boeing has been working on as an Advanced Concept Technology Demonstration project. The EUE phase means another round of ground and flight tests, along with "hands-on operation" for the Air Force and other potential users.

Why use a laser when the Air Force already has a wide array of missiles and bombs at its disposal? (The standard gunship variant of the C-130 can already be equipped with 40mm and 105mm cannons.) "Little to no collateral damage," Boeing says, thanks to the laser weapon's "ultra-precision engagement capability." That is, think laser pointer with extreme prejudice.

In addition, the laser would presumably strike more or less silently--no thump-thump-thump or rat-a-tat-tat. (Note, 11:30 a.m. PDT: A reader writes in to say that high-power lasers operating in the atmosphere are anything but silent, perhaps because of ionizing the air - a la lightning.)

For use against missiles, mortars, and the like, laser weapons are intended to heat up and weaken the metal skin of the projectile, causing it to rupture while in flight. Against ground targets, the ATL could, say, zap fuel tanks or even vehicle tires--if it could hold focus long enough.… Read more

Scarab, a robot developed by Carnegie Mellon University with support from NASA, is about to be tested at Hawaii's Mauna Kea volcano to prove its fitness for the extreme conditions of space.

The robot was developed by the Lunar Rover Initiative, a group of scientists from the Field Robotics Center at Carnegie Mellon's Robotics Institute. The test mission, intended to mimic a lunar rover mission, will have Scarab climb, drill, extract, and analyze samples, CMU announced Tuesday.

The dormant volcano and Hawaii's highest mountain, Mauna Kea is best known for its elite observatory of astronomical telescopes. But on this mission, scientists will be looking within instead of out at the universe.

The 400-kilogram (880-pound) robot has a suspension system that allows it to climb or drive on steep inclines of sand and rock. Scarab's November 1-13 mission will take place about two-thirds of the way up to Mauna Kea's peak at an elevation of 9,000 feet. The robot will take samples from the dormant volcano.

One of Scarab's innovative tools specifically being tested during the November mission is a drill from Norcat (Northern Centre for Advanced Technology) and a chemical analysis device from NASA.… Read more

One technology more than any other has stood out as a success story for the U.S. military in Iraq: unmanned aerial vehicles, or UAVs.

The best-known of the UAVs, the MQ-1 Predator, has evolved from its early use as simply a reconnaissance and surveillance aircraft to become a highly valued weapon in its own right. Armed with Hellfire missiles, it can both track enemy combatants and fire on them. A more recent version of the Predator, called the MQ-9 Reaper, was specifically put into service as a "hunter-killer" drone.

The Pentagon has been so impressed with the … Read more

The Defense Advanced Research Projects Agency's (DARPA) Strategic Technology Office is looking for a submersible aircraft design and invites you to come up with a concept.

Performance requirements call for an aircraft that can cover 1,850km by air or 185km by sea, or 22km underwater in eight hours or less. And this is not some miniature pool hopper; DARPA wants it to be able to carry a crew of eight and a 2,000lb payload.

Speculation on design suggests an old-school snorkel to provide air supply for the power plant while your flying fish is in submerged mode, … Read more

A prototype high-tech cuff that detects and treats bleeding from combat injuries got a step closer to the battlefield Monday when Siemens Healthcare announced an exclusive contract with the Defense Advance Research Projects Agency to develop the device.

The Deep Bleeder Acoustic Coagulation cuff, or DBAC, is designed to limit blood loss from penetrating wounds to limbs--as in the case of a gunshot injury--thus reducing the risk of limb loss or death.

Once the cuff is applied, ultrasound technology within the device automatically would identify the location and severity of the bleeding. This in turn would trigger therapeutic ultrasound elements … Read more

On Monday, a 4-foot-long helicopter equipped with an artificial-intelligence system developed by computer scientists at Stanford University flew over the campus, according to Reuters. The helicopter had taught itself to fly by watching the aerobatics of a radio-controlled helicopter flown by a human. Also on Monday, I got my Warlock to level 66 in World of Warcraft. Yeah, I think I need to reevaluate my priorities.

The self-controlled mini-hopper performed flips, rolls, pirouettes, stall-turns, knife-edges, and an inverted hover over a field. Adam Coates, a Ph.D. student who worked on the project, said the machines can fly maneuvers at … Read more

As Hurricane Ike descended upon the upper Texas coastline late last week, it was business as usual for the Hurricane Hunters of the U.S. Air Force.

Aircraft and crews of the 53rd Weather Reconnaissance Squadron were flying nonstop in and out of the most violent parts of Ike on their standard mission--getting data on hurricanes from the inside. That information can help improve the accuracy of National Hurricane Center forecasts and alerts by some 30 percent, no small matter at all in trying to prepare public authorities and the general public for what to expect.

The Hurricane Hunters fly … Read more
