Scientists suggest modifying cars to hit fewer hedgehogs

Placing ultrasound repellants on cars could protect the spiny mammals. Up to one in three hedgehogs in local populations die on roads. Breakthroughs, discoveries, and DIY tips sent six days a week. When it comes to how animals use ultrasound, chances are you immediately think of bats and their amazing echolocation ability. However, researchers have discovered another--arguably much cuter--animal that can also hear ultrasound, with significant implications for its conservation.
