A closer look

Paleontologists are firing high-energy particle accelerators at dinosaur-era amber just to map the internal organs of trapped bugs. Synchrotron microtomography uses incredibly bright X-rays generated by electrons racing at near light-speed to peer inside fossils without destroying them. This non-destructive 3D scanning is so unimaginably precise that it has revealed the microscopic brain structures of 100-million-year-old insects trapped in petrified tree sap.
