Antscan is a revolutionary first step to the new way researchers will study ants. It provides micrometer-resolution 3D reconstructions, uncovering amazing details of these marvelous insects. Launched by a team co-led by biodiversity scientist Evan Economo from the University of Maryland and Julian Katzke, Antscan features high-resolution images of 792 ant species across 212 genera, covering a significant portion of the described diversity in ants. This unique collaborative work emphasizes the amazing armored exoskeletons of ants. It removes the cover from their fightin’ muscles, nerve cords, digestive tubes and, yes, needlelike stingers.
The Antscan database is an interactive, easy-to-use online portal. It’s a groundbreaking, award-winning tool that allows patrons to experience breathtaking photography without leaving the glare of their computer screens. Using synchrotron micro-computed tomography (micro-CT), the group imaged both hard and soft tissues in stunning detail. This dataset, representing over 200 terabytes, has been further standardized and made widely accessible to researchers all over the world.
Antscan’s public availability marks a milestone in the scientific community, providing a permanent record of insect anatomy that can be revisited long after fragile specimens degrade or populations vanish.
Cutting-Edge Technology Behind Antscan
Our research team envisioned the Antscan dataset as the culmination of expeditions to museum collections around the world. They shipped more than 2,200 carefully-preserved ant specimens to the micro-CT beamlines at the Karlsruhe Institute of Technology’s synchrotron light source facility in Germany. This time-consuming and meticulous scanning process provided the opportunity for unprecedented imaging of the external and internal structures of ants.
Evan Economo emphasized the significance of this technology, stating, “This is kind of like having a genome for shape.” As part of this effort, the team used neural networks to automate the identification and analysis of anatomical structures, vastly improving efficiency. This innovation has opened new doors for researchers to investigate the complications of ant biology.
Users can digitally “dissect” these insects. As the video above attests, users can rotate and zoom in on different parts of the seemingly simple ant’s anatomy. Now researchers can finally take a detailed look at the key features of the biomineral outer “armor” layer. They can study high-resolution 3D renderings of the brain, gut, and sting apparatus. These technologies have created exciting new platforms where we have the potential to learn why ants spend so much energy creating their hard outer shell. Second, they allow cross-species comparative studies.
A Resource for Science and Beyond
Antscan’s massive dataset is more than just a scientific curiosity. New possibilities for its application continue to appear, especially in the fields of art, education and outreach. Julian Katzke noted, “It is an extremely rich dataset that can be used for a number of different applications in science, but for the arts and outreach and education.” This versatility is a testament to the platform’s wide applicability outside of classic biological research.
Recently, researchers such as Cameron Currie have hailed Antscan’s usefulness in comparative studies as a tremendous asset. “It provides an outstanding resource for comparative work across ants,” he stated. This one resource has the potential to greatly improve learning across a wide range of disciplines—entomology, ecology, and evolutionary biology to name a few.
Moreover, Marek Borowiec highlighted that “the full advantage of this dataset will be realized when these methods are deployed.” Once researchers fully harness what Antscan’s capabilities have to offer, they can further transform research in morphological studies. Its effect can only be compared to the previous two decades worth of large-scale genomic databases.
A Step Toward Future Innovations
As Antscan consistently grows in popularity among the scientific community, it’s bigger significance for future innovations is starting to crystallize. Economo expressed his hopes for the platform’s broader applications: “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.” This vision is emblematic of an exciting new frontier wherein biological data can catalyze significant breakthroughs in scientific and technological innovation.
David Blackburn emphasized the value of making museum collections more accessible. “The more people that access and work with the stuff in our museums, whether it’s physically or digitally, the greater value they add.” By making high-resolution anatomical data freely accessible to all, Antscan promotes collaboration between researchers and increases public interest in biodiversity.
