Antscan, a groundbreaking NASA-inspired citizen science platform, provides never before seen micrometer-resolution reconstructions of ants as varied and unique as you are! The AntScan team has used state-of-the-art micro-CT technology to provide us a full-dimensional tour of ant exoskeletons. They’ve shown us the detailed internal anatomy, including musculature, neuroanatomy, digestion, and needle-like stingers. This collaborative, educational initiative further advances STEM learning by fostering a greater overall knowledge of ant morphology and diversity. It’s an incredible advancement in scientific research and increases public educational outreach.
Evan Economo and Julian Katzke are co-leads of the Antscan project. They use cutting-edge micro-CT beamlines at the large-scale research facility synchrotron light source of the Karlsruhe Institute of Technology in Germany. The team had to carefully process about 2,200 preserved ant specimens across these beamlines. To do this, they constructed a standardized dataset that is now publicly available. Now available online, this comprehensive digital library includes 3D volumes of 792 species. It addresses 212 of such genera, or the majority of described ant diversity.
Detailed Insights into Ant Anatomy
Antscan’s high-resolution reconstructions reveal the extraordinary intricacies of ant anatomy. Scientists can now better explore the detailed features like armored exoskeletons and a wealth of different internal organs. The Antscan crew smartly leveraged synchrotron micro-CT technology to take still frames of internal anatomy in a matter of seconds. This process enabled them to avoid the arduous staining and soft-tissue contrast-producing pre-treatments that are typically required.
“It is an extremely rich dataset that can be used for a number of different applications in science, but also for the arts and outreach and education.” – Julian Katzke
This new dataset provides researchers with the opportunity to develop a richer understanding of individual species. It lets them find patterns that cut across the entire ant family tree. Or so Antscan, the creator of the previous discovery, thought! It showed that a biomineral “armor” layer, first discovered in one Central American leaf-cutter ant in 2020, is widespread among fungus-farming ants. This finding highlights the dataset’s value in investigating evolutionary convergences and adaptations of traits across different ant species.
Interactive Accessibility for Researchers and Enthusiasts
Antscan acts as a dynamic web-based platform. It allows people to rotate, zoom and virtually “dissect” insects all from the comfort of their laptops! That accessibility makes the study of ant morphology available to all of us. Researchers, educators, and the genuinely curious can now explore the data in unprecedented depth and detail.
“The easy-to-navigate platform provides a powerful transparency and educational outreach tool. As David Blackburn notes, “The more people that access and work with the stuff in our museums, whether it’s physically or digitally, the greater value they add.” Antscan broadens access to this treasure trove of information to a wider audience. This new initiative is designed to inspire young people to get excited about entomology and related STEM disciplines.
A New Era for Morphological Research
Antscan is an exciting example of a profound change in how researchers study morphology. Large-scale sequencing projects like the Human Genome Project and programs like GenBank have transformed how we interact with DNA. Antscan seeks to inspire a comparable transformation in the world of morphological research. The possible uses of this massive dataset are endless, from the improvement of robotics to enhancing engineering designs.
“This is kind of like having a genome for shape.” – Evan Economo
Researchers are beginning to scratch the surface of what’s possible with Antscan. They expect that using new approaches to process this dynamic dataset will reveal its full benefits. Marek Borowiec emphasizes this sentiment by stating, “The full advantage of this dataset will be realized when these methods are deployed.”
Evan Economo envisions even broader implications: “I would really like to see these big libraries of organismal form one day be useful for people in robotics and engineering so they can mine these data for new kinds of biomechanical designs.” The burgeoning intersection of biology and technology lays a rich, fertile landscape for future innovations inspired by Antscan’s discoveries.
