A recent analysis in Science of more than 116,000 bird songs has revealed that the astonishing variety of passerine birdsong is built from just eight basic acoustic motifs, like trills, whistles, and harmonic notes. Learn more on #WorldAnimalDay: scim.ag/3SziyeL

Adding Australasian ants to www.antscan.info project: micro-CT scans of ants for trait ecology and evolution research. The synchrotron was super cool and a lovely team to work with!
