Don’t let the bedbugs bite
A trio of teens has found a nontoxic way to stop bedbugs dead in their tracks. The method relies on a mesh of fibers that a bug can step into easily — but never leave.

The road less worn
Two teens have found a new use for old tires. By grinding them up and adding them to asphalt, the old rubber can create stronger, longer-lived roads. And the bonus: The process recycles tires that might otherwise have been burned, creating pollution.

Urine may make Mars travel possible
On Earth, urine is a waste. En route to Mars, it could be a precious renewable commodity: the source of drinking water and energy.

Sending student science to space
Two teachers describe how they worked with the Student Spaceflight Experiments Program to get middle-school scientists excited about research and space.

Filter lets in only the right light
Scientists have built a light filter that only permits light coming from one desired angle to pass through. Built from alternating layers of transparent materials, it could help minimize the glare in telescopes and cameras or boost the efficiency of solar cells.

Laser tweezers grab nano bits
An optical fiber, a bit of gold and a laser make up a new type of tweezers. Scientists may soon use it to pick up and move around individual viruses or proteins.
