Electronics may confuse a bird’s ‘compass’
Birds use Earth’s magnetic field to help guide them as they migrate. A new study suggests that electromagnetic radiation given off by some electronic devices may act like “noise” and confuse the long-traveling birds.

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.

For better weight control, fiber up!
Certain types of fiber suppress appetite, at least in mice. Found in fruits, vegetables, oats and barley, this fiber breaks down in the gut to release acetate. That travels to the brain, where the chemical prompts the release of hunger-fighting hormones.
