A friend of mine is designing a clinical trial to determine the comparative effectiveness of different methods of pain control during IUD insertion. The problem is, there isn’t a lot of existing literature on what women are actually being offered out in the real world, and what does exist is pretty low quality.
If you have an IUD, and if you were offered pain control measures during insertion, what were they? How effective those measures were isn't really relevant here, because that's what the trial is designed to figure out; I’m just trying to help her get a sense of what the current state of practice is so that the design of the study can be as robust and relevant as possible. For Science!

I'm trying to brush up on my geology, a science that pretty much passed me by, which is frustrating when people I work with casually start talking about Cambrian this, and Triassic that. Where can I find a large poster / chart detailing all the geological epochs and periods? The chart produced by the Geological Society of America
is a good start, but it would be more useful if it was, say, annotated with important events ("Angiosperms evolved here! Gondwana separated here!"), and it it had maps of the positions of continents on it at various times. Has anyone seen anything like this? My searches for geology posters have mostly turned up pictures of mountains, or "Geology Rocks!" logos...

We have a Cuckoo "pressure rice cooker"
(model HD1054F) that my husband and I got for our wedding. It makes great rice! Now, I want to explore its actual "pressure cooking" side. But it doesn't seem to cook at as high a pressure as a standard pressure cooker. How do I determine the pressure (in psi) that it uses? [more inside]

Looking for videos to create a youtube playlist to entertain a group of science-minded teenagers for about 30 min that are largely visual. Sound is fine but the bulk shouldn't be someone talking to the class like an instructor - visualizations are best - ideally they should look really, really cool. Class is engineering focused, but chemistry, robotics, wobbly bridges, comp-sci, biology, are all welcome. [more inside]

How do other languages (non-English) express the scientific term 'race?' vs the colloquial?
In taxonomic terms, the word "race" is 90% used as a misnomer in US discourse. This is rooted in "Social Darwinism," or contemporary racist applications of seminal evolution concepts. This colors verbiage across the sciences, especially the social sciences. To wit, the term 'racism' is in fact based on a dehumanizing paradigm.
So, um, how does this shake out elsewhere? [more inside]

I am looking for people's experiences of demonstrating the basics of how a clinical trial works to the lay person. My audience will be pretty broad - from school children to adults - so I will need to keep it pretty sort and simple. I need something I can use when visiting schools to big events - I have heard of people using cake and chocolate to demonstrate randomisation/placebo etc - has anyone on here done that and have any pointers? TIA!

What is this thing my cat brought to my porch? http://i.imgur.com/cejZcGe.jpg
It appears to be something between an animal fetus and organ. When I turned it over it looked the same on the other side. There were no visible eyes/mouth/features. It was larger than a quarter and there was no blood present. A possum visits regularly, and the area has many moles, birds, and raccoons.

I was researching sequential eating and would like some advice, here are my thoughts and questions: It seems that it takes (on average) 2-4 hours for foods or beverages to leave the stomach.
I was wanting to eat/drink something specific every two hours.
I have 8 hours to sleep every night, and I like to eat right before sleep as well.
This leaves me with 16 hours in a wakened state. Or, 9 segments of eating/drinking. (I drink water right when I wake up)
On the basis of sequential eating, what are some useful tips/advice I could keep in consideration while putting together snacks of 1-3 things?
It's looking like 4 meals a day, 5 drinks a day, alternating every two hours. OR, what I would rather prefer, is eating 9 meals a day (fruit in the morning with my water), and drinking 6oz of water every hour on the dot. Any advice would be greatly appreciated.

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.

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]

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 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?
