In case you can't get enough news about graphene:

As a species, humans have evolved to have certain strengths and weaknesses. While we don't have the sonar-like range finding capabilities of bats or dolphins, we do have the brains to engineer a device that can give that capability to us.

Researchers at the University of California, Berkeley have done exactly that in their development of tiny ultrasonic microphones made from graphene.

[...] At only one atom in thickness, graphene possesses the key properties of strength, stiffness, and light weight; so it is extremely sensitive to a wide-range of frequencies. In this case, the microphone can pick up frequencies from across the human hearing range—from subsonic (below 20 hertz) to ultrasonic (above 20 kilohertz)—and as high as 500 kHz. (A bat hears in the 9 kHz to 200 kHz range.)

Daredevil, here we come!

    It was obvious to me but most other members of that site are not what you and I regard as critical thinkers.

    I figured I should call their security on the phone but could not find their number. So I scouted around in the Contact Us section for a little while, but when I realized that they supplied no way to actually Contact Them, I figured that their venture capitalists were going to get what they deserved.

    And know I wont tell you which website other rhan that their stock valuation might take a hit real soon now.
