High-Energy Physics Probes Ancient Fossils

Thanks to particle accelerators, paleontologists can now don the best X-ray specs in the world

Lately, paleontologists have been choosing odd bedfellows to study rare, precious fossils: particle physicists. At the annual meeting of the American Association for the Advancement of Science this weekend, several researchers reported on how synchrotron particle accelerators—the world’s most powerful X-ray machines—are revealing new details about biological relics such as amber-trapped Cretaceous bugs, the celebrated bird-dinosaur Archaeopteryx, and what appears to be the world’s only fossilized brain.
