Bats See in 3D Even in the Dark

Animals navigate and orient themselves to survive – to find food and shelter or avoid predators, for example. Research conducted by Dr. Nachum Ulanovsky and research student Michael Yartsev of the Weizmann Institute’s Neurobiology Department, published in Science, reveals for the first time how three-dimensional, Read More...

Hair Sensors Assist Bat Flight

Bat wing membranes are not sheets of naked skin. Instead, they are covered with tiny hairs. In some species, such as Tadarida condylura (Molossidae), the hairs aid in streamlining the airfoil (Figure 1), thereby reducing drag. In others the wing Read More...
