I hate bugs, and I have one that is in my space. Can the generous and awesome amateur (or professional) entomologists of MetaFilter help me identify it, and perhaps give me a general sense of how dangerous it might or might not be? [more inside]
need some pointers as to research strategies/leads to find out about the state of the art knowledge about the moon in 1878, with particular reference to things arising in or popular in the French scientific community. First thoughts are Times digital archive and to look for an encyclopaedia of similar date. Any leads appreciated.
What ways exist where would one keep up with big ideas or events in the academic publishing world, in some kind of passive way that involves me regularly checking in and picking out what's interesting and saving those for later. [more inside]
I'm preparing a timeline of important virology-related events for work. We have some HIV-related and some bacteriophage-related material as well as some cancer-related stuff and some "greatest hits" (x-ray diffraction patterns, transduction, discovery of interferon). I'd like to expand our timeline to cover more diverse kinds of virology-related stuff. [more inside]
I was wondering if the static shocks that a person normally gets in the winter are caused by an excess of electrons, a deficiency of electrons, or if it happens both ways but just depends on the circumstance.
Throwing away all the political and financial pressure that dilutes and warps science, if one wants to engage in scientific inquiry and be productive and contribute in some small way to humanity's scientific understanding of the cosmos, how does one go about things? Can we boil things down to simple generalized steps -- brief enough to put on a wall plaque -- starting with the evaluation of an experimental idea (is it a "good" experiment?) all the way through to publishing one's reproducible results?

A recent post to the blue proposed a set of equations that changed the word. As a computer professional, I'm curious, which algorithms transformed the world? [more inside]
All my life, people have complimented me on my abiity to write well. In middle and high school, it was writing good chapter summaries, literary analyses and essays for homework using flowery language. In college, it became about construction and the flow of ideas, and I found myself to be reasonably adept at that as well. I'm currently jobless ( looking for my first job at 25), and when people chime in with suggestions on how to fix that, they can't understand why I poo-poo the idea of writing professionally out of hand. Help me develop my writerly mind and get myself out of the English class for good. [more inside]
Around 10 years ago I read a science fiction paperback novel (that I think had been recently published) and I can't remember what it was called. All I can remember is that it was largely set on a spacecraft and there were a group of Humans investigating a series of horrible deaths on a planet and on another spacecraft. They found the bones of the missing people buried on the planet they were investigating.

Hey MeFites, I'm really trying to expand the use of digital technology in my classroom. Unfortunately, the resources at my school are fairly limited. However, I do have access to $1200 in grant money, assuming I can write a compelling enough proposal. Help me find some affordable tech for my classroom! Needs of class inside. [more inside]
I have a large tupperware full of a crystalline white powder. It could be sugar, or it could be xylitol. How can I tell? So far I've found two possible ways: burn it and record the energy per gram; feed it to dogs. I would prefer not to do the second, as xylitol kills dogs. I'm open to the first, if someone wants to link me to a good experimental method for such. But I'd really love a third way.
Chemists! I have a question about chromatography. Specifically, what is the best way to isolate a specific molecule, if I want to produce large volumes of this isolated molecule? [more inside]
I'm looking for well-written and researched "objective and scientific" studies of the paranormal. I am aware that those are loaded words, particularly around this topic, and I doubt there is a book that settles questions about paranormal activity and abilities once and for all, but essentially I would like to read books written by authors who don't have a pre-determined agenda in favour or against these types of phenomena being real.

What are basic pieces of kitchen science that would be helpful for me to know? I'm most interested in baking but cooking is okay too. Things like the effect of salt or liquid on a recipe or whether I want my bread dough to rise in a dry or humid area and why would be really great. I'm okay at following recipes but I'd absolutely love to know why different ingredients and combinations have different effects and how I can use that to my advantage. [more inside]
We have a naming convention for our cats - so far they are all science related terms that start with M. We have Magnet, Möbius and Meniscus. Now we have a new little fluff ball - a black kitten with a white tuft on her chest. Can you help think of a name for her? So far we've thrown around Muon, Mendel (too masculine) and plain ol' μ.
In a discussion elsewhere on the internets a twist on a common science fictional transportation technology was proposed. A spaceship leaps from one point in space to another, but while it is instantaneous for the passengers, the transit actually takes some small amount of time longer than light would take to cover the distance (let's say the Planck time). Would the time delay prevent the violation of causality? It appears that everyone is staying in their light cones, what am I missing? [more inside]
Assuming nothing goes catastrophically wrong (which might not be a good assumption to make, unfortunately), I should be getting a PhD in about 18 months. I'm about 90% sure that I don't want to stay in academia. What steps can I start taking now to have a smoother career change? [more inside]
What kind of skill sets does one need to be of best help to addressing climate change? It would seem like the most obvious choice is to major in environmental science. Otherwise, maybe political science to deal with legislators and capital hill? Or "who cares what you study undergrad" and go to law school?
I read a while ago a quote from Oppenheimer that eloquently expressed the idea that once a scientist gets in his or her head the idea that a result is achievable, he or she will not be stopped until that result is achieved. He referred to the scientist, though the sense in which he meant the term might better map to what many consider an engineer. [more inside]
Today, I was enthusing about a photograph from the surface of Mars, and a friend responded along the following lines: "I find it hard to get excited about it when there are so many starving people here on Earth.

I love thinking about the vastness of space, the long arc of the cosmic time scale, the complexity of connections in various systems. I find thinking about these big ideas creates a pleasurable feeling in my body, and putting them to music is even more moving. Examples of favorites include Peter Mulvey's "Vlad the Astrophysicist" and Symphony of Science's "We Are All Connected". What other songs combine music and big scientific ideas about how small and insignificant humans are?

As a by-product of this FPP about a very large water slide, have just been involved in an inconclusive and heated argument about the physics aspects.

I'm under the impression that factory farming is insane and detrimental to our continuing existence as a species. However, it's difficult to find resources that further explore the environmental impact without the Peter Singer-type ethical concerns of animal welfare, which is appreciated but sometimes lacks a certain scientific rigor. Are there good, go-to resources that explore the environmental impact of factory farming that refrain from diversions into animal rights?
If you had a multivariate equation whose output variable is mean surface temperature on earth, what would be the rough beta value for distance from the sun (in millions of miles or whatever)?

My second grader is doing a presentation on magnets. He's read books and can tell you all sorts of cool things about magnets, which is probably fine for second grade. But the really interesting question is not "what do they do?", but "why do they do it?" Can anyone explain how magnets work at a level second graders might understand?
Cosmos has me very intrigued. Assume I know less than a 5th grader. I am looking for: book recommendations for basic astronomy concepts; blogs; podcasts for beginners; good audio books; and documentaries. If you wanted to teach an adult about astronomy where would you start?
In studying for my Behavioral Statistics final (it’s a statistics class dealing with psychology research methods) I’ve realized something. I actually kind of enjoy math. As long as I don’t have to memorize formulas (as long as they are right there as I’m going through the work) it’s actually kind of comforting and fun. In fact, every math class I’ve taken in college (I’ve taken two remedial algebras, college algebra, and regular statistics before this class) I’ve enjoyed and made an A in. I’m really struggling about what I want to major in (I’m in psychology but I don’t have it in the gas tank to get a PhD), but I know that a lot of people don’t like math. They don’t get it. I do, so I’ve got something there, right? The only problem is, I don’t know what to do with it. These are the parameters… maybe you can think of something that fits? [more inside]
I'm trying to remember a series of shows broadcast in the late 1970s or maybe as late as 1980 or so. It explained science topics through the lens of recent discoveries or advancements. It might have been PBS but I think it was a "special broadcast" on network tv. I loved them and got all excited when one would be on, so I don't think it was regular or weekly. The only one I specifically remember was on the brain, told through the story of a little girl (?) who needed brain surgery. It wasn't for specifically for kids, but I recall them being very upbeat and "yay science!" They were broadcast in prime time, probably 8 PM. Also: it's definitely not Connections. Apologies - this may the the vaguest TV-related AskMe yet!
So, I recently got selected to do undergraduate physics research this summer. Great! Awesome! Yay me! However, my research advisor has asked me to use something called IDL to analyze tomographic images of compounds and turn them into 3D images. This is good news, because IDL is used a lot by astronomers to analyze astronomical data, and I want to continue my education in astronomy. But, I've never used IDL ever before. I'm not even sure exactly what it is (a programming language?). My question is this: how do I get up to speed so that I can hit the ground running with my research? Difficulty: Research begins in two weeks. Details: [more inside]
We can't figure out a good title for my daughter's Science Fair Project. The school wants the 4th grade children to basically do the whole project at home with guidance from the parents. My daughter's experiment is on why apples turn brown and she is learning about why the lemon juice worked (learning about acids and bases, etc.) The poster board we will use will have a title on it. The teacher wants us to think of a good title, and it does not necessarily have to be the question, "Why do apples turn brown". It can be a clever, or interesting title that goes with the experiment. At first we thought about, "An apple a day keeps the doctor away." But then we thought it was too long, and it also might be presumed that her project is about apples and how they are healthy.

I have an odd job interview coming up. I need advise on a children's book to read to a grown up audience and a two minute poem or "fun" monologue to recite.

Please help me find a mystery book from my childhood. I am stumped. It would have been in the mid 70s, probably between 1974-77. I think it was science/nature-related book that may have been one of a series. What I remember is a hard-cover book, and on the back inside cover there was mounted a round plastic disk with an arrow inside, sort of like a compass. It was visible though holes in the pages and front cover. There were questions with multiple choices on each page, and you would close the book and knock on the cover a certain number of times to make the needle point to the correct answer on a corresponding page. That sounds crazy even as I type it, but if someone could find this book (or even corroborate my memory) I would be eternally grateful.
