Hugh Herr is building the next generation of bionic limbs, robotic prosthetics inspired by nature’s own designs.

The Library of Congress has acquired The Seth MacFarlane Collection of the Carl Sagan and Ann Druyan Archive, and has begun to catalog and digitize the materials in it, posting them to the library’s website.
