Tonight my 8 year old niece told me that for Christmas she wants a blanket for her bed that has a giant picture of Earth on it. I asked her if she saw this somewhere, and she told me that she just thought about how cool it would be in her own head. I tried doing a Google search, but I'm having no luck. Anyone have an idea of where I might find such a thing? Thanks! posted by ezrainch at 7:59 PM - 8 answers
I am a biologist moving to San Diego. My work will take me all over the state, including SoCal deserts and Baja California. There are a million natural history books out there - which ones are worth the money?
I want a good plant book for sure. But I would also love recommendations for geology, herps, birds, general natural history and anything else an outdoorsy gal might find interesting. posted by intoxicate at 7:32 PM - 11 answers
Help me understand the difference between 28dB, 38dB and 48dB.
I'm thinking about buying a fridge, and the fridges I'm considering have noise levels ranging from 28dB to 47dB (according to the latest fridge assessment in Choice).
Fridges with a 28dB noise level rating are too expensive for me, though, so I'm trying to find something I can afford but which won't annoy me too much (I'm sensitive to the noise of a buzzing fridge). What I can afford tends to be somewhere in the mid-30s dB range.
But it's no use going into a noisy showroom and trying to properly gauge how a fridge will sound in my quiet home. So I'm wondering if there's a way I can test these different noise levels at home before I buy, to see what's the difference. posted by paleyellowwithorange at 5:12 PM - 9 answers
We have a spare room that we're turning into an Arts & Science room for the kids (13 year old girl and 8 year old boy). It's in a walk-out basement with a painted concrete floor and a window. We have some ideas but little knowledge in how to setup a room for them to create and explore. We have a cheap beginner's chemistry set, some art and craft supplies, and...that's about it. What ideas can we implement with the little expertise and money we have? [more inside] posted by medarby at 5:37 AM - 15 answers
I'm looking for a low-cost app or site where you can explore the muscular structure, how they attach to the skeleton, isolate a muscle by turning on/off other muscles, etc. My chief aim is for fitness purposes so I can understand my own body better before my chiropractic visits. Book or other learnig tool recommendations are welcomed! [more inside] posted by film at 9:11 AM - 7 answers
Physics geeks! Help me save energy! How do I estimate how much less energy will be used by light siding vs gray siding, based on an experiment with small boxes? I made some identical boxes, put them in the sun, measured temperatures, and am trying to figure out how to scale up. The net has info about different roof colors, but not siding colors.

If hydrogen fusion in the center of the sun suddenly increased by a factor of 10^3 to 10^10, how long would it take until the energy burst reaches the surface and is radiated away? As I understand it, energy is transfered via convection and radiation within the sun and may take tens of thousand of years until reaching the surface and being radiated away. Would this hold even when the energy flux is much bigger? [more inside] posted by Triton at 1:41 PM - 8 answers
I'm interested in joining the UK personal genome project (PGP), as I like big science and think that the project looks interesting and has some admirable aims. However, I'm not so sure about having my genetic information freely available on the internet, and I don't fully understand what the risks of this could be. I found this article on the gurdian, but any more information, resources or advice would be appreciated. Thanks. posted by Ned G at 4:45 PM - 3 answers
Why is the log phase of bacterial growth called the log phase, when it actually resembles an exponential curve rather than a logarithmic curve? I'm really dusty on my math, can someone explain this to me? posted by jolyn at 8:59 AM - 15 answers
Dear Hive Mind,
My friend (a graduate student in psychology) wants to collect physiological measures for her dissertation. However, she doesn't have much money with which to do so. What is the cheapest way for her to accurately record the heart rate of some undergraduates? How much more will it cost her to be able to export the data to a computer?

I am a male. I am the family historian. In an effort to fine-tune my own research into my maternal grandfather's family (the "Jones"), I have my male first cousin take a Y-DNA test, since he has the "Jones" Y-Chromosome (I have my Dad's Y chromosome).
Lo and behold, the test comes back with a perfect match, and a predicted Most Recent Common Ancestor within 3 generations. I have researched back farther than that and I know all of their names. None of the last names match.
My occupation doesn't take me anywhere near genetics... but I am assuming that a Y DNA match with a MRCA that close should have the same surname for his male ancestor, correct? Except if there's been adoption or infidelity or rape, correct?
I sent the results to my cousin, prior to the lightbulb going off over my head. He knows a lot less about this than I do. He hasn't called me yet, but what if he does? Should I just let sleeping dogs lie? Ugh! posted by anonymous at 8:46 AM - 24 answers
I would like to find a cite-able reference for an anecdote that I heard — drinking orange juice is correlated to a lower frequency of automobile accidents. The point of this example is that correlation is not causation by using a true correlation with a ridiculous causation. But, where did I hear of this example? Is the correlation true?

Bought these cream & brown hollow "pebbles" at a Beijing market a few years ago. I think they are grown, because each has a hole, like it was picked from a tree maybe. They are extremely lightweight but have a hard exterior. The lady who sold them to me cautioned they would break if dropped. I'm going back to China soon and would like to buy more, if I know what to ask for. [more inside] posted by MuckWeh at 2:48 PM - 3 answers
Decades ago I read a description of Milton Erickson's most interesting/spectacular cases--how he used hypnotic suggestion to help people overcome their obsessions and other life problems. The one that has stayed with me was a description of dealing with a man who had been given to an orphanage at birth and had spent his childhood and adolescence growing up in a variety of institutions. His life as an adult was one of petty crime, unemployment, no relationships of any kind. The hypnotherapist spent many many hours over the course of months with this man giving him a new set of memories--here you are with your loving family on your fifth birthday,here you are with your friends in eighth grade, etc--just built up a whole life of new memories for him. This enabled the man to make a better life for himself.
I have checked out "An Uncommon Casebook: Complete Clinical Work of Milton H. Erickson, M.D." and although I saw many case histories I remembered reading, I didn't see anything like this.
Am I looking in the wrong book? Am I looking up the wrong hypnotherapist? Any help or direction would be much appreciated. posted by uans at 8:36 AM - 5 answers
