Getting married in a few months, which means I want to start any facial/beauty regimens now. I don't usually do this stuff, so am entranced by the field of options. However, I know that this field contains the biggest BS factor of any out there.

Please also tell me which of the things I'm considering looking at are drecht or dangerous crazytown. Help me not waste my money or wind up maimed. [more inside]

When I was a kid, I was totally enamored of dinosaurs. I seem to have lost my affinity for them in the years since. I quit paying attention to developments in paleontology. Apparently there's been a lot that I missed, like that the dominant theory now is that modern birds are descended from a dinosaur species (I think?). And I hear velociraptors had feathers. So I need not just updates, but a good primer for adults because I've forgotten everything I used to know about them.
Can anyone recommend some good modern books or documentaries on dinosaurs to rekindle the flame of dino-love?

Dear MetaFilter, I am new to this forum and this is my first post, hi!
I am in a bit of a pickle about a work project, and hope that I may be able to get some help by some fellow sciencey people. The science forums are rarely read and badly out of date, or I would have posted at one of those.
I have a deadline for a miRNA PCR experiment, and I have already run the cDNA and PCR for the miRNA. All I have to do is run the miRNA on a gel.
We don't have acrylamide! And neither does our neighboring lab. We only have Agarose with which to make gels, which is only for large fragments, not small miRNA fragments of 20-40 bp.
As the percentage of agarose in the gel goes higher, the smaller the size of the base pairs are that can be measured. Could I increase this percentage enough to work for miRNA?
Out of respect for the community that doesn't like line returns, I have entered the specifics of this post in the Extended Explanation box, because to me, this post reads like a jumble of nonsense without some kind of organization. [more inside]

I've noticed that most of what I read about science and technology is universally optimistic about the pace
of knowledge (if not necessary its use
). From tech journalists to science fiction writers everyone seems to believe that the possibilities of technology are boundless and the pace of scientific discovery is, if anything, accelerating and always will be.
My question is: Is anyone credibly arguing the opposite? [more inside]

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...

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]

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 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?
