I've been told recently that collecting micrometeorites is as easy, basically, as placing a clean surface outside and picking through the debris you collect because thousands of tons of space dust and debris fall to Earth every day. That can't be all there is to it, can it? How do you know whether you're looking at Earth dust or space dust? [more inside]

For a research project, I have several pieces of equipment mounted on top of a large metal rotating circular surface. At the moment, all equipment is battery powered. I would like to come up with an inexpensive way of getting DC power and signal wires to a computer off the surface to analyze data in real time. Besides that constraint, going down thru the center isn't really an option since the rotating shaft is solid metal. [more inside]

I recently accepted a sales position within a company that sells laboratory equipment. (i.e. centrifuges, GC's, HPLC's, Thermal Cyclers, etc) I have no previous lab or science experience, so learning about a myriad of highly technical products/methods is a quite challenging. My main challenge comes from the fact that I need to engage in conversations with scientists, chemists, biologists on a daily basis. With no previous lab experience, I've been having a hard time talking to them on technical level. [more inside]

Two years into a Ph.D. program in the biological science (in the US) and I am in a lab doing research. The lab I'm in takes a hand-off approach to our research, so much of the motivation to do projects must come from me. Unfortunately I'm the kind of person who needs deadlines and strong guidance, and without these two things I've begun to drift a little. Any tips for keeping my eyes on the prize and staying immersed in my field? [more inside]

I have recently been introduced to the concept of pseudoreplication as a mistake that people often make when using inferential statistics to evaluate treatment outcomes. My field (evolutionary and conservation biology) makes heavy use of inferential statistics, including techniques that are vulnerable to pseudoreplication, yet nowhere in my formal education have I been taught about how poor experimental design and lack of statistical rigor can lead to fallacies like this. My personal statistical proficiency is poor, but I am working to remedy that. To that end, could folks help me by identifying and ideally explaining whatever other potential pitfalls you can think of, and explaining how they can be avoided through careful experimental design and data-analysis?
I'm wondering, after breakfast, and a shower, and a commute, and coffee - what is next? [more inside]
I'm using Python in my research now to build some models and analyze some data. I've done this with Matlab and R in the past and became fairly used to running individual lines or blocks of code at a time and doing a lot of interactive printing and plotting from the console. This behavior seems to be a bit more difficult in Python and I'm trying to find the best way to be productive. [more inside]

Years ago I saw a flickr set (I think) of the covers of a vintage series of books on science and engineering. Each cover (under the dust jacket) was a single color and featured a simple embossed diagram of the book's topic (e.g rockets, electricity & magnetism), with no text. They were gorgeous. Please help me find the series title!

So I hear that aluminum is pretty bad for your body (and maybe is linked to Alzheimer's?). I also hear that alum (which is used to close nicks after shaving) is the name of an aluminum compound. The majority of info about alum crystals for personal hygiene tends to be on "natural living" web sites and the like, so my main question is: is there any actual scientific study either way as to the safety of such a thing being rubbed on your face on a regular basis?
