Methods of Fighting Mold on Books Developed by Medical Scientists
Medical scientists report two mold combating methods from the Journal of the American Medical Association. B D Wyke of the University of Sydney advises keeping humidity below 75 percent and using silica gel on shelves to prevent mold, with reactivation by heating. Dr Duncan C Heathing ton of Duke University recommends wiping moldy bindings with a thymol crystal mercury bichloride ether benzene solution, effective on books and leather items but hazardous for clothing.

Explosions Reach High Speeds Across the Scene
Dr. George B. Kistiakowsky, Harvard chemist, notes shock waves from blasts travel about 8 000 yards per second, over 16 000 miles per hour. He explains detonations are instantaneous once triggered, with ammonium nitrate burning before detonation and dynamite caps firing minutes after ignition.
