Fossil is the oldest-known scorpion

Scientists studying fossils collected 35 years ago have identified them as the oldest-known scorpion species, a prehistoric animal from about 437 million years ago. The researchers found that the animal likely had the capacity ...

A timekeeper for siesta

Circadian clocks must be flexible and they must be able to adapt to varying environmental conditions. Otherwise, it would be impossible for living beings to change their patterns of activity when the days get shorter again ...

Mosquito eye inspires artificial compound lens

Anyone who's tried to swat a pesky mosquito knows how quickly the insects can evade a hand or fly swatter. The pests' compound eyes, which provide a wide field of view, are largely responsible for these lightning-fast actions. ...

New artificial compound eye could improve 3-D object tracking

If you've ever tried to swat a fly, you know that insects react to movement extremely quickly. A newly created biologically inspired compound eye is helping scientists understand how insects use their compound eyes to sense ...

Fungal compound deodorizes skunk smell

Being sprayed by a skunk is no fun for people or their pets, and the strong, stinky secretions can serve as a nasty reminder of the wildlife encounter for days or weeks. Available "de-skunking" formulas often either don't ...

3-D models reveal why bigger bumblebees see better

By generating 3-D images of bumblebees' compound eyes, researchers at Lund University in Sweden have discovered how bumblebees differ in their vision. The results could contribute to increased knowledge about the pollination ...
