So. About that heated rivalry, huh.

Dave is looking awfully slim starting out. I don't think he learned the BMI lesson. He probably does deserve another shot, though.
Oh, Nicole is back, too. She was great.
The good news is I don't think there will be any temptation to build a boat. It looks like there will be a river and plains, maybe? No oceans to call out to them.

Polymer Skins That Change Color and Texture When Exposed to Water
Researchers at Stanford University recently came up with an interesting way (Phys.org summary) to create patterns and colors that emerge when a polymer is exposed to water. Although the paper itself is sadly paywalled with no preprint available, it’s fairly easily summarized and illustrated with details from the Supplementary Data section. The polymer used is poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS), which when exposed to an electron beam (electron-beam lithography) undergoes certain changes that become apparent when said water is added.
The polymer is hygroscopic, but the electron beam modifies the extent to which a specific area swells up, thus making it possible to create patterns that depend on the amount of electron beam exposure. In order to ‘colorize’ the polymer, complex cavities are created that modify the angular distribution of light, as illustrated in the top image from the Supplemental Data docx file.
By varying the concentration of IPA versus water, the intermediate swelling states can be controlled. Although this sounds pretty advanced, if you look at the supplementary videos that are already sped up a lot, you can see that it is a very slow process. Compared to an octopus and kin whose ability to alter their own skin texture and coloring is legendary and directly controlled by their nervous system, this isn’t quite in the same ballpark yet, even if it’s pretty cool to watch.

She is the one I think most deserved a second shot at it. And, I guess the producers agree, since she's the first one they introduced.
I don't get why Britt is back. I mean, I liked him OK, but he was a tough guy and was out pretty quick.
Randy!? They brought barefoot Randy back? Now they're just being silly.
