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.

From chirps to'hellos': Why some birds talk like people Brains, bonds, and a strange voice box help some birds mimic our speech.

'Rats have a bad reputation, but they actually make really great companion pets.' Rats are much more clean than their reputation suggests. Breakthroughs, discoveries, and DIY tips sent six days a week. A non-profit organization in Massachusetts received a boatload of pet rats in need of new homes. An individual in northeastern Massachusetts surrendered 163 rats in early February. That's almost 60 percent more than the total number of rats that were adopted from the Massachusetts Society for the Prevention of Cruelty to Animals-Angell (MSPCA-Angell) in 2025 alone.
