Mycoremediation of explosives

Didn't see this posted before... New Scientist ran a bit about a design this guy had for self-disarming bombs using white-rot fungus to digest the explosives:

Patent for the design is here:

Invention: Explosive-eating fungus

* 18:09 21 February 2006
* NewScientist.com news service

For over 30 years, Barry Fox has trawled through the world's weird and wonderful patent applications, uncovering the most exciting, bizarre or even terrifying new ideas. His column, Invention, is exclusively online. Scroll down for a roundup of previous Invention articles.

Explosive-eating fungus

Could fungus counter the explosive power of dynamite? That's the idea behind a patent filed by Robert Riggs of Texas, US.

When explosives are used for mining or demolition, some may fail to detonate and get lost in the rubble. Riggs reckons the remedy could be to mix pellets of dormant fungal spores in with the explosive charge before inserting the wick into the explosive package.

The dry spores lie dormant while the explosives are in storage and, if the charge detonates as intended, will get blown to smithereens.

But if the explosive fails to detonate, water from the air should migrate down the wick and into the charge. The spores should then germinate and devour the charge, rendering it harmless.

The white-rot fungus Phlebia radiate is particularly fond of high explosives, according to the patent. And the speed at which it gobbles the stuff up depends on the number of pellets added: 5 pellets per stick for slow degradation or 30 to make it safe after just a few days.

Soldier sensor

For most people, being swamped with information is just annoying. But for soldiers, pilots and police officers it can be a matter of life and death. So a device that prevents urgent communications from getting lost in bureaucratic babble, patented by US defence firm Honeywell, could prove invaluable.

Honeywell has been investigating ways to reduce information overload under a grant from the US government's Defense Advanced Research Projects Agency (DARPA).

The company's idea is for soldiers' uniforms to conceal an electrocardiogram, galvanic skin response detector, and respiration and blood pressure sensors. These instruments should be able to tell when a person is breathing hard, sweating and has a racing pulse. If so, the time is probably not right for HQ to ask them any mundane questions.

The same system should be able to sense when a person is calm and breathing easy, so ready to receive a load of information.

If all the sensors suggest that the solider is dead, the patent suggests that important messages should be relayed to another whose sensors still show signs of life.

Bubble scanner

Magnetic resonance imaging (MRI) can give doctors a very clear picture of a patient's heart as it pumps blood. But MRI machines are huge and expensive, and Philips thinks it can get equally clear images using much cheaper ultrasonic scanning equipment.

The trick is to inject a volley of microbubbles ? mirometre-sized shells containing air or inert gas ? into a patient's blood. These harmless bubbles resonate at megahertz frequencies and reflect the ultrasound to create a dark blob on the scanning screen.

Increasing the strength of the ultrasonic beam destroys some bubbles, which creates recognisable "markers" within the mass of bubbles. The movement of these markers reveals blood flow and, when the blob reaches the heart, they should provide a clear ultrasound picture of the way its muscles are pumping.
