New paper on evolution of ant spinescence in Pheidole

A new paper from the lab was published today in the Biological Journal of the Linnean Society focusing on aberrant spinescent phenotypes in Pheidole (including the famous dragon ants). We look at spinescence from a number of angles including phylogenetic, ecological, geographic, and 3D morphology. This study sheds light on the complexity of the issue of spine phenotype evolution. There are a number of open questions and some big mysteries. For starters, why the heck has spinescence evolved so many times in the Indo-Pacific, but no spiny Pheidole in New World?

HoloLens comes to the Economo Unit

How would you like to be in the same room as an ant the size of a horse? In reality that’s a ridiculous idea, but in augmented reality anything is possible. This week, OIST’s Biodiversity and Biocomplexity Unit tested a new augmented reality device: the Microsoft HoloLens. Pavel Puchenkov of OIST’s Scientific Computing & Data Analysis Section designed a demonstration using a 3D-scanned model of the newly discovered ant species, Pheidole drogon. With the HoloLens, researchers were able to explore this species’ exceptionally spiny shape.

actually see the ant, but it all looks very dramatic

While the applications available for the HoloLens are currently limited, the opportunities quickly become apparent. The ability to display holographic renderings of specimens in 3D has the potential to turn any room into a stunning museum exhibit. It’s clear that this technology has the potential to create or enrich experiences that we can use to communicate life’s diversity and evolutionary history.
