Berkeley Lab physicists develop way to digitally restore and preserve
Library of Congress-sponsored research will help Berkeley Lab physicists digitize audio data encoded in the hill-and-valley surface of Edison wax cylinders. This three-dimensional scan of a portion of a cylinder was acquired with a non-contact confocal optical probe, and provided by STIL SA of Aix-en-Provence, France.

The 1995 discovery of the top quark and singer Marian Anderson’s 1947 rendition of Nobody Knows the Trouble I’ve Seen may seem unrelated. But through an interagency agreement with the Library of Congress, the same technology used to study subatomic particles is helping to restore and preserve the sounds of yesteryear.
“We developed a way to image the grooves in a recording that is similar to measuring tracks in a particle detector,” says Carl Haber, a senior scientist in Lawrence Berkeley National Laboratory’s Physics Division who developed the technology along with fellow Physics Division scientist Vitaliy Fadeyev.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
