ANOTHER ANATOMY POST! Only three vertebrate groups have successfully evolved flight: Birds, Bats, and Pterosaurs, which are NOT dinosaurs, and are an extremely diverse group of reptiles! Pterodactyl is not the only one. However, birds ARE dinosaurs. Avian dinosaurs!

Wings are not some extra structure you tack on to a creature and somehow the arms go away— they ARE arms. Think about that when you are designing creatures with wings and also giving them arms. That means your creature has six limbs.

Next anatomy post: The anatomy and evolution of DRAGONS. If you guys have any requests, feel free to send them in!

"The defensive slime of hagfishes contains thousands of intermediate filament protein threads that are manufactured within specialized gland thread cells. The material properties of these threads rival those of spider dragline silks, which makes them an ideal model for biomimetic efforts to produce sustainable protein materials, yet how the thread is produced and organized within the cell is not well understood. Here we show how changes in nuclear morphology, size and position can explain the three-dimensional pattern of thread coiling in gland thread cells, and how the ultrastructure of the thread changes as very young thread cells develop into large cells with fully mature coiled threads. Our model provides an explanation for the complex process of thread assembly and organization that has fascinated and perplexed biologists for over a century, and provides valuable insights for the quest to manufacture high-performance biomimetic protein materials.” Via.

"Polyoxometalate ligands play a key role in facilitating a ruthenium catalyst access to a high-valent reactive state in aerobic oxidation in water. In their [paper], C. Bo, M. Bonchio et al. show that the reaction involves novel ruthenium–peroxo and oxene intermediates embedded within a totally inorganic POM environment. This breakthrough perspective is one the central themes of the European COST action entitled Polyoxometalate Chemistry for Molecular Nanoscience (PoCheMoN).” Via.

A preview of a project I’m working on this month: tracing slow motion flight videos and plotting the curves I find. I’ll hopefully be posting the finished version by the end of September!
