Listening to the past, recorded on tin foil and glass, for the first time in over a century

Towards the end of the 1800s, there were three primary American groups competing to invent technology to record and play back audio. Alexander Graham Bell worked with with Charles Sumner Tainter and Chichester Bell in at their Volta Laboratory in Georgetown, Washington, D.C., while Thomas A. Edison worked from his Menlo Park facilities, and Emile Berliner worked in his independent laboratory in his home. To secure the rights to their inventions, the three groups sent samples of their work to the Smithsonian. These recordings became part of the permanent collections, now consisting of 400 of the earliest audio recordings ever made. But knowledge of their contents was limited to old, short descriptions, as the rubber, beeswax, glass, tin foil and brass recording media are fragile, and playback devices might damage the recordings, if such working devices are even available. That is, until a collaborative project with the Library of Congress and Lawrence Berkeley National Laboratory came together to make 2D and 3D optical scanners, capable of visually recording the patterns marked on discs and cylinders, respectively.

I've got moves you haven't even seen yet

What is the relationship between the optical groove in a record or wax cylinder and sound, and how can we use this to recover analog recordings from the past? Dr. Carl Haber explains IRENE (.pdf; begin at slide 44 for audio samples).

Digital Morphology, for when you really want to get up close and personal.

Digimorph, headed by University of Texas professor Timothy Rowe, is a collection of 2D and 3D cross-sectional images of everything from dinosaur skulls to fertilized emu eggs. Using an advanced X-ray Computed Tomographic scanner, researchers are able to capture minute details of a subject's internal structure. DigiMorph provides data on almost 300 species in the form of Quicktime animations, 3D movies, and stereolithography files which can be used (with the proper tools) to create your own 3D specimen.

If you've ever wondered exactly what's up with the stimulating hummingbird or the confounding platypus, now's the perfect time to take a more in-depth look.
