Scientists are at the Stanford Linear Accelerator Center (SLAC) are using a particle accelerator to help recover a lost work by Archimedes. The Archimedes Palimpsest is a parchment book that once contained copies of Archimedes’ works, but was later erased to be reused as a prayer book. The palimpsest contains the only copy of *Method of Mathematical Theorems* and only copy of *On Floating Bodies* in the original Greek.

SLAC’s website also has a press release about the current state of research into the existence of the pentaquark, a theoretical particle made up of five quarks (all known particles made up of quarks only take two or three). The verdict? Not proven.
