The MIT engineers used nanotech to measure the thickness of a single scale (about 500 millionths of a meter thick), and decipher the makeup of its four different layer materials. They discovered that the materials, in tandem with the geometry and thickness of each layer, all contributed to a pretty amazing suit of armor.

They even tested the armor plating by "biting" scales that had been surgically removed from a living fish. What they discovered then was that P. senegalus armor will probably replace the bulky ceramic plates that adorn our fighting men and women in warzones today.

The P. senegalus armor kept the crack localized by forcing it to run in a circle around the penetration site, rather than spreading through the entire scale and leading to catastrophic failure, like many ceramic materials.

Lighter, thinner, and better? I think with those kinds of results soldiers and law enforcement officials alike could probably turn a blind eye to the fishy smell. Either that, or baking soda just became the next indispensable item in their arsenal next to bulletproof vests. [MIT]

The technology is described as an example of “neuromorphic engineering”—hardware and software that tries to emulate human intelligence. Basically, the binoculars point out objects that our brains might have noticed, but not fully processed. The subconscious can detect multiple things at once, but the conscious mind can only focus on one thing at a time. By collecting data using human eyes and then passing the data back to the brain, the binoculars more or less add a second processing loop.

One possible problem: How to fine-tune it so that the binoculars don't just pick up on useless, distracting noise. Brains look for patterns in everything, and will sometimes find them even where they don't exist (i.e. Astrology). What if for every rocket launcher it did notice before us, it also pointed out how one specific mountain range in the distance looks like your mother-in-law's face? [Slashdot via Gizmag]

Scientists suggest that the brace could be used by campers and soldiers to power GPS locators and satellite phones in areas with limited access to electricity. It could also charge prosthetic knees, eliminating the need for periodic surgery to replace the batteries in the joint.

The current version of the knee brace is just a proof-of-concept; the team plans to make the device less bulky while still retaining its energy harvesting capabilities. We think this is a great idea with lots of potential (even if it was created in part by a University of Michigan professor). Hopefully we can get a working model before CES next year so we'll never need to worry about our laptop running out of juice. [Science via Science Daily, Reuters, BBC]

Scientists have invented a gel that mimics human tissue. By combining the gel with the microchip, chances that the body will reject the device are far less likely. The entire project is said to be five years from implementation.

Personally, I'd love to see these microchips developed for civilian use, especially for diabetics and those who need constant blood work. But when framed as a government, military initiative, the altruistic potential can be scared off by Big Brother. [intelligencedaily via inquirer]

These vests can be adapted to be used on the battlefield, yes, but we'd like to see them make a version for the Xbox 360. Did I feel a left arrow on my back? That means I need to flank left. Down? Duck. All of them go off at once? Oh, right, I'm being chainsawed. – Jason Chen
