These incredibly detailed images are scans of a brain of a bumblebee – measuring less than a centimetre across – created using a new technique called micro-CT scanning. Similar to hospital CT scanners used to visualise tumours inside patients or see the structure of a human brain, micro-CT uses precision X-ray beams to scan through objects hundreds of times in all directions. These X-rays are collected and assembled using a powerful computer, creating a three-dimensional image revealing a wealth of tiny details. Unlike other high-powered microscopy techniques, which use potentially damaging chemicals to preserve cells, micro-CT can be used to observe tissues in their natural state, providing a more accurate picture. And although it may not seem like we have a lot in common with a buzzing bumblebee, studying the structures of their brains and how they relate to their function helps to shed light on our own grey matter.
