‘Echoes’ Found In Bat And Dolphin DNA


Scientists have found a striking similarity in the DNA that enables some bats and dolphins to echolocate.

A key gene that gives their ears the ability to detect high-frequency sound has produced the exact same amino acid changes over time in both creatures.

The researchers report their findings in the journal Current Biology.

It may be the first time that identical genetics has been shown to underpin the evolution of similar characteristics in very different organisms.

The Army’s $10M Spy Bat is Still Too Big

 The Army’s $10M Spy Bat

The University of Michigan’s Center for Objective Microelectronics and Biomimetic Advanced Technology (COM-BAT) is working on building a robot bat that would perform long-range reconnaissance for the U.S. Army, but U.Mich is currently struggling with miniaturizing components in order to make the bat small enough to be stealthy.
