My nails grow so very slowly, and I want longer prettier nails. Are there any supplements or external topical treatments to help them grow faster that have actually been proven to work by science?
Here's a pattern that happens to me a lot. Say I sleep 4-5 hours on Sunday night, instead of my preferred 7-8. I feel fine all day Monday, then sleep 8 hours Monday night. On Tuesday, I feel exhausted and mentally foggy. Is this pattern documented in others? Is there a physiological explanation? [more inside]
What is this flower? It's been identified as a yellow lupine, but my better half doubts it and wants a second opinion. Since I don't know any group of people more opinionated that Mefites, here we are.
Can anyone identify the bug in this paperweight? Thanks in advance!
I'm looking for an example of a common chemical reaction in which a specific combination of a few reactants yields one product, but the introduction of one additional reactant yields an entirely different product. This is for the purpose of a literary metaphor. The less esoteric the reaction, the better (i.e. if it consists of commonly recognized substances that would be helpful).
There are leeches in a pond near here. What would happen if, out of curiosity, I let a leech latch and lunch? Any significant danger to me or the leech?
No one seems to know when the tributary of the White River now called the James River (in Missouri) was named or who named it. Henry Schoolcraft traveled to the Ozarks in 1818-1819. In a View of the Lead Mines of Missouri (1819) he refers to it as the James River. In the 1820s, it was called the James Fork of the White in references in dealing with the relocated Delaware Reservation on that stream. [more inside]
From an ecological standpoint: When there is roadkill in the road, is it better to swerve around it, or run over it? [more inside]
While hiking to the Sespe Hot Springs in the Los Padres National Forest over the weekend, I kept hearing this vocalization. (The low moaning one that repeats six times.) What creature is it?
An animal's den has appeared. Gophers which were near the den before have disappeared. There are bobcats and foxes around here and now and then scat turns up that doesn't belong to a domestic pet. I would like to get a few pictures of this new resident. [more inside]
I own a record store and am considering a new location as I'm out of space at my current one. However, I’m pretty innumerate and not spacially inclined. I’m therefore having difficulty determining which of these two locations will allow me to display the most inventory. Could those of you good with spaces and floorplans please help me decide? Details inside. [more inside]
I would like to read any great science writing out there on cats -- particularly, that focusing on interspecies communication. But I'll take whatever I can get! [more inside]
I came across this weird bug feeding on a lilac bush while walking my dog this evening. I have never seen anything remotely like it. [more inside]
I'm looking for the best book (or other source) on nutrition. Not a diet book. Not anything with an opinion (to the extent that's possible). I just would like to read a book that describes what's going on with our bodies and the foods and nutrients we put into them. How exactly are the major nutrients metabolized? In what order over what time period? What are the functions of the various amino acids? What do the various vitamins and minerals do? And so forth. I just want to know what's going on, because I can't read a thousand diet and exercise books all pushing some points over others. I have a technical background, so I can handle and appreciate decently-complex explanations of biochemistry and the like. In fact, I like that stuff. Just as long as it starts at the beginning and builds up to that. So just, the cold, hard, comprehensive facts on nutrition, please. [more inside]
In my workplace there is a reference to a "12% NH4OH" reagent that is prepared by diluting 20 mL of NH4OH to 50mL with H2O. It's obvious to me that this isn't a v/v concentration but I cant see how the formula makes it either a 12% w/w or a 12% w/v concentration. Assuming that we're starting with reagent grade (29% assay) NH4OH, which is it... and how does it work out to 12%? [more inside]
Potato batteries and various forms of citrus batteries are, as best as I can tell, most accurately described as chemical batteries. But that sounds so boring! Do they not have a more sciency name? Like electroconvalent batteries or something? [more inside]
I am on the hunt to learn more about nature! I live in southwest michigan. I'm hoping to find a book (supplemented by an app maybe) that will help me identify plants. My criteria are: (a) pocket/bag sized (b) more information than just what the plant is named (c) good form factor/durability, (d) good for a beginner - I don't even know the difference between a beach and a birch, I probably don't need a book that has 107 different types of maple tree listed out - but maybe I do! Please help a beginner
I'm looking for a manufacturer-published SDS or a peer-reviewed paper that explicitly states the hazard information and precautionary statements associated with wild-type C. elegans. [more inside]
A simple mechanism made of two identical gears can be used to reverse the direction of rotation without changing the speed of rotation. Is there a simple planar linkage (e.g. 5-bar or 6-bar) with only rotary joints and rigid links that can do the same thing? [more inside]
