Friday Cephalopod: Stand determined

Dr. Walter Arnold (University of Vienna) and colleagues were interested in studying how Northern ungulates cope (physiologically) with limited food supplies during the winter months. Ungulates are known to reduce energy expenditure during the winter. A new study published Wednesday in the American Journal of Physiology-Regulatory, Integrative and Comparative Physiology describes how these animals adjust their nutritional intake. Dr. Arnold’s team examined intestinal transport…

Coyne in DC

Jerry Coyne is is on tour for his new book Fact Versus Faith: Why Science and Religion Are Incompatible. That title’s a little vague. What do you suppose the book’s about? It turns out that he was making a stop in Washington DC. Since that’s not so far from my digs in Harrisonburg, I decided…

For more than a decade, biologist Mariam Barlow has been working on the theory that administering antibiotics on a rotating basis could be a solution to antibiotic resistance. After years of research, Barlow had lots of data, but she needed a more precise way to make sense of it all — something that was so specific it could easily be used to treat patients. So, she joined forces with a team of mathematicians. And the amazing results could help solve an enormous, worldwide problem.

Octopus-inspired robotic device

Speaking of octopuses, the ability for the animals to squeeze through narrow openings has inspired the creation of a new surgical robotic device that can squeeze into a patient’s body. An EU team created STIFFness controllable Flexible and Learnable manipulator for surgical OPerations, dubbed “STIFF-FLOP”, made from silicone. Unlike conventional robots used during surgeries, the…

New research shows how octopus skin is able to respond to variations in light

I am thrilled to see Dr. Stan Lindstedt’s review article published in the April 2015 issue of American Journal of Physiology: Regulatory, Integrative and Comparative Physiology from his 2013 August Krogh lectureship at the annual Experimental Biology conference. My original blog from the lecture can be found here. Dr. Lindstedt and co-author Dr. Niisa Nishikawa (Northern…

Mary’s Monday Metazoan: Sawing

Friday Cephalopod: Legal precedent

By carrying that coconut, octopuses of this sort made a change in their legal status necessary. The extent of octopus intelligence is debated, at least among vertebrates, but there is evidence of pretty complex behavior, including possible tool use. See, e.g., J.K. Finn, T. Tregenza, and M.D. Norman, “Defensive tool use in a coconut-carrying octopus,”…
