Chemical training in the lab. Giliane has set up a (safe) experiment for us to test whether acid should be placed into water, or should water be placed into acid. We ensured it was the correct way (acid into water!) before Tiffany tried it out!

Landmarks and Lifeforms: Linking science and art at the Limerick City Gallery of Art
Maria participated in a panel discussion at the opening of the new exhibition ‘Landmarks and Lifeforms’ by Irish artists Frieda Meaney and Danny Osbourne, chaired by Newstalk’s Éanna Ní Lamhna. The exhibition features prints and installations by Frieda focusing on evolution, change, and transformation, and lava sculptures and vessels by Danny. The panel discussion was very interactive, with lots of participation by the audience, and ranged in topic from origins of the Earth, climate change, and dinosaur evolution to creativity and the common methodical process that lies at the foundation of all scientific and artistic inquiry.

This is a histological section through a cuttlefish (Sepia officianalis) ink sack, the black-stained cells can be easily identified. Although it has been known for millennia that cuttlefish and other cephalopods produce ink, exactly how they produce melanin in their tissues is poorly known. Tim is currently looking into how and where melanosomes are produced in cephalopod tissue.

Maria was invited to give the first Quercus lecture of 2017, titled ‘Beyond the lab: making science accessible to all’. UCC’s Quercus students are recognised as some of the most talented in the university; the the Quercus Talented Students’ Programme aims to support and promote excellence in academia, sport, creative and performing arts, active citizenship and innovation/entrepreneurship. The goal of the Quercus lecture series is to inspire students, and staff, by presenting thought-provoking lectures by some of UCC’s most inspiring academics.

Some of the palaeontology research group went to the BT Young Scientist competition during the weekend, where we displayed our own exhibit “Walk Like A Dinosaur”. This project was created by palaeontologists in UCC’s School of BEES, UCC’s School of Engineering and UCC’s Department of Computer Science. A sensor was attached to the legs of visitors to our stand, which was used to estimate their speed whilst walking / running, and what species of dinosaur this was equivalent to! Each member of the public that participated received a personalized talk about their species. We also brought along some trilobite fossils, an ammonite fossil, a fossilized Megalodon tooth and a cast of Microraptor!
