Aero Evo: August 2012
http://aeroevo.blogspot.com/2012_08_01_archive.html
Thursday, August 16, 2012. I will be resuming the Dragon series on Aero Evo soon. I am currently at the annual American Society of Biomechanics conference (ASB 2012). Some good talks this morning; I was particularly intrigued by the experiments of T. Gross from Washington University showing that the primary trigger of bone loss following muscle paralysis is not. The loss of mechanical loading. An endocrine or paracrine effect seems to be the primary influence. Very cool stuff. Subscribe to: Posts (Atom).

Aero Evo: Mosquitoes in the Rain
http://aeroevo.blogspot.com/2012/06/mosquitoes-in-rain.html
Friday, June 29, 2012. Mosquitoes in the Rain. A recent paper by Dickerson et al. in PNAS. Explains how mosquitoes are able to fly effectively in rainy conditions (remember: many of them hail from humid tropics), even though a single raindrop by weigh 50x what a mosquito weighs. If you cannot access the full paper, feel free to read this summary on BBC. It even inspired a comic. Subscribe to: Post Comments (Atom). Subscribe To Aero Evo. PLoS Biology: New Articles.

Aero Evo: Aquaflyers Again: Skates and Rays
http://aeroevo.blogspot.com/2012/07/aquaflyers-again-skates-and-rays.html
Tuesday, July 10, 2012. Aquaflyers Again: Skates and Rays. Previously I wrote a bit about the wonders of aquaflying in penguins. This time, I thought it would be fun to write briefly on some of the interesting details of aquaflying in skates and rays. Not all rays are aquaflyers in the sense I am using here. Many rays propel themselves by moving a series of waves down either pectoral complex like this. One thing that is. Advance Ratio = v/(f * d). For a flapping animal, we have to take into account the r...

Aero Evo: Updates
http://aeroevo.blogspot.com/2012/10/updates.html
Thursday, October 11, 2012. Well, it's been months since I ran off to ASB and promised more blog posts, so it seems I should give an update. I have had to focus on two major tasks since moving to Los Angeles (other than making my apartment livable and such): teaching human gross anatomy and starting work on a new team project in collective behavior and swarming. All that said, I will. October 11, 2012 at 5:35 AM. From hawks to fish, eh? Thats quite a drastic change! October 11, 2012 at 6:36 AM. WE ARE PU...

Aero Evo: Guest Post: Thin vs Thick Wings
http://aeroevo.blogspot.com/2012/07/guest-post-thin-vs-thick-wings.html
Thursday, July 5, 2012. Guest Post: Thin vs Thick Wings. Press release on it can be found here. Thin And Thick Wings. Why didn't the massive investment in the development of aircraft wing sections have anything to offer to sailboats? July 6, 2012 at 5:14 AM. Interesting context, particularly for the propatagium. January 9, 2013 at 6:27 AM. I am curious about one thing, could you please tell us your place of birth? Subscribe to: Post Comments (Atom). Subscribe To Aero Evo. PLoS Biology: New Articles.

Aero Evo: Why Turkeys are Like Rockets
http://aeroevo.blogspot.com/2012/07/why-turkeys-are-like-rockets.html
Friday, July 13, 2012. Why Turkeys are Like Rockets. The photograph at left was taken by David Hone at the Pittsburgh Zoo. They are actually quite common as wild individuals in that surrounding area, so it's a bit amusing that the shot ended up coming from the zoo. In any case, I give you this turkey to highlight two brief myths. Myth 1: Galliform birds (chickens and relatives) are "poor" flyers. Myth 2: Big birds have to run to take off. So they are taking off at a steeper angle than many smaller birds.

Aero Evo: Wait, penguins can fly!?
http://aeroevo.blogspot.com/2012/04/wait-penguins-can-fly.html
Monday, April 16, 2012. Wait, penguins can fly! In short, no, penguins cannot fly in the traditional sense. But they can. Aquafly, which is today's topic. The image at left is a reconstruction (by Chris Gaskin) of Kairuku. As described by Daniel Ksepka and colleagues. The full paper is available here. For free. Kairuku. Hails from the Oligocene. Penguins have quite a good fossil record, and we know from the record that early penguins were often quite large ( Kairuku. Or the even earlier Waimanu,. As it t...

Aero Evo: Pterosaur Water Launch: Preliminary Results
http://aeroevo.blogspot.com/2012/04/pterosaur-water-launch-preliminary.html
Friday, April 6, 2012. Pterosaur Water Launch: Preliminary Results. Back again for more water launching goodness. These results were presented at SVP 2011; with luck they will be finalized and appear in a formal journal (PLoS ONE) this summer. Here's what I get for Anhanguera. Using the technique from yesterday's post:. The initial escape phase could be accomplished with a net remaining acceleration of 17.6 m/s. And an acceleration of up to 39.2 m/s. One important note is that this water launch model mak...
