Diana Wray Yay, this was one of my questions from last month! Thanks for answering it, guys. Any chance of getting the names of the chemicals the mosquito leaves in the skin?

Diana Wray Do those dead stars eventually orbit into the center and join the supermassive black hole or do they just stay there around the center, orbiting forever? (Until another galaxy passes by and disrupts the whole thing, I mean.)

Ivan Pejić Fun trivia: USB data is transmitted as a differential signal over a twisted pair of wires (interference immune design pattern) so more or less poor design of connected devices makes them susceptible to RFI/EMI and you end up paying for a ferrite choked USB. :D

David Gell You've done a few shows about Earth's moon, but you haven't done one that I can find explaining why the Moon is not a moon at all, but rather a sister planet. A planet is gravitationally "owned" by a sun whereas a moon is gravitationally "owned" by a planet. If you calculate the G-ration of Sun:Moon vs Earth:Moon using Newton's Law of Gravitation, you can see that the ratio is in excess of 2. In order for the Moon to be a moon, it would need to be less than 1. So, IF the Moon is really a planet, how can it orbit Earth -- if, in fact, it actually does (as opposed to the two sister planets actually in elliptical orbits about the Sun that are everywhere concave)?

AuntieSash Hazlewood So timely. Playing certain games makes one or both arms tingle because of the particular way my arms sit - often for long periods of time. I stop and shake out my hands to make things work again, but always wonder if I'm doing lasting damage. My doc said "change your position" and I thought "I'd have to remap all my hotkeys!". Maybe I'll try putting a cushion under my arm to reduce the pressure.

Diana Wray Sorry, this post was about the biofluorescent turtle. I mistakenly said it was bioluminescent - not the same thing. Still, here's the article. http://www.cnn.com/2015/09/29/world/biofluorescent-sea-turtle-discovered/ Cool stuff.
