Bacteria Used To Fix Cracked Concrete 177
An anonymous reader writes "Researchers at the UK's University of Newcastle have created a new type of bacteria that generates glue to hold together cracks in concrete structures — that means everything from concrete sidewalks to buildings that have been damaged by earthquakes. When the cells have been germinated, they burrow deep into the concrete until they reach the bottom. At this point, the concrete repair process is activated, and the cells split into three types that produce calcium carbonate crystals, act as reinforcing fibers, and produce glue which acts as a binding agent to fill concrete gaps."

Well, since grey goo is such an abstract concept, they thought they would rather use something more concrete ...

"and they have a built-in self-destruct gene that prevents them from proliferating away from the concrete target."
That never works in the movies. One cosmic ray and the gene is replaced by another one that says," invade humans and turn them into statues."

Call me when they can pour this Bacterial pudding into a bullet wound and have it heal up...that's the future I'm waiting for. Then I can finally start my crime-fighting vigilante spree.
Or...you could put this pudding IN the bullet, then as soon as you'd got shot, you'd start healing. Joscelyn Elders would finally be vindicated!

Living, moving statues with a ravenous, uncontrollable hunger for the brains of the unpetrified. Prepare yourself for 90 minutes of bad stoner jokes.

I see what you did there.

They'll only be statues when you're looking at them.

Okay, we've fixed the holes in the concrete, and made holes in people. Seems to me the logical next step is to fill the holes in the people with concrete.
