So I am a bit obsessed with fireflies and other bioluminescent creatures. Help me find some experts and gain expertise! [more inside]
I'm looking for suggestions for non-fiction books of an ilk I can only describe as biographies of place; works that strongly evoke a sense of landscape. [more inside]
Specifically, how likely is something like the "jackpot" in Gibson's new book to happen? Spoilers below the fold. [more inside]
What is this (famous?) psychological experiment/demonstration/phenomenon? [more inside]
We'll be on holiday with our two just-teen kids in a house on a Spanish island that's off both the water and the electricity grid, but with plenty of sun and wind. What are some cool little projects we could do - without having to ship out complicated gear/components - to own and appreciate the situation, and its potential? Self-built solar cooker? Makeshift wind turbine? Would love suggestions plus pointers to how-to's. [more inside]
I was looking for a good place to buy equine chorionic gonadotropic (eCG) hormone for science reasons today and stumbled across this listing for the more commonly used hCG. It's listed as being sourced from "Human Pregnancy Urine." Where on earth do biomedical companies get enough human pregnancy urine to distill a compound like this? Is there some sort of secret cottage industry of pregnant ladies selling their pee to biotech companies? Where does the pee come from?
NASA has identified that Kepler-452b is Earthlike. How do we find out more about Kepler-452b and similar planets? [more inside]

Hi. When I'm walking around, the sun is unpleasantly bright and hot, which makes me wonder: How much stuff, and what type of stuff, would we have to dump into the sun in order to stop fusion from happening? Or is there no such amount of anything? [more inside]
Asking for a tattoo artist. [more inside]
For reasons perhaps best understood by wasting way too much time in Kerbal Space Program, the difference in fuel and cost between a flyby and an orbiter can be considerable. As such, NASA's New Horizons craft zipped through the Pluto system at considerable speed, before continuing out into the Edgeworth–Kuiper belt. Will the craft produce high-resolution maps of the complete surfaces of both Pluto and Charon, or will the flyby approach only allow for a portion of the surface of each body to be surveyed?
Spoilers for Kim Stanley Robinson's "Aurora" ahead. So, the story is like this: A multigenerational arkship is on it's way to Tau Ceti, they find their primary target for colonization hostile and discuss whether to move to another planet in the same system, live there in domes while terraforming it. One reason for not doing this is stated thusly: [more inside]
Inspired by this New Yorker piece, it seems like there ought to be a list of natural disasters that will possibly, probably happen and that we're really not preparing for (like the Yellowstone supervolcano). [more inside]
So, imagine we have a 100 meter tall tower, a 100 kg weight, and a rocket. Consider the following two, very similar scenarios... [more inside]
Found a good-sized skull off the NC coast and I'd love to know the species. Possible odotoceti/toothed whale? [more inside]
I've grown tomatoes three times now, and have noticed that my tomato plants seem to "give up" certain branches/stems. The affected stems turn yellow and do not flower; if I don't prune them off right away, they eventually turn brittle and snap off the plant easily. [more inside]
