What professional medical equipment, techniques and possibilities exist to record sounds inside the body? [more inside]
Lately I've been running across a lot of highly theoretical science and technology information that I don't understand. I would like to be able to recognize quackery and fringe science, as well as when technologists (especially programmers) are reinventing the wheel and claiming to revolutionize things, so I don't get steered in the wrong direction. I'm looking for heuristics. [more inside]

I told a friend about a SF story I'd read, but I can't find the title and author. the plot: a person working for a satellite company is mapping Greece, and comes up with the idea of following the most difficult route at any given point. [more inside]
Earlier today I was warming up a test tube in chem lab by placing its bottom in a warm stream of water from a faucet and I noticed something peculiar; the stream of water seemed to capture the test tube and hold it in place. [more inside]

If enriching uranium with a gas centrifuge costs 50 to 60 kW·h (180–220 MJ) of electricity per SWU, is it possible to adapt the formulas given there to calculate the energy needed to extract pure CO2 directly from the atmosphere? (assuming e.g. 0.04% concentration). Asking as a complete science n00b.

Spouse has career in naturalist/nutrition based field. Tons of unscientifically supported woo. Spouse feels incredibly validated by field; feels ideas/ideals are all part of little guy's fight against big pharma/ big ag/ big whatever. Remuneration is based upon getting clients to sign up for coaching sessions where this unscientific information is pitched. No products are being sold, just diet/health/exercise/spiritual plans. In the past 2 years, income has gone up from 2,000 to 5,000/yr. I feel guilty being a part of a marriage where I feel like my partner's income is a result of fleecing at best or profound ignorance at worst, likely the latter. [more inside]
Spending time with geologists recently makes me want to find ways to live in the universe as it actually is (to the best current knowledge). I know, in a shallow way, that my body is a thriving microbial ecosystem, that the planet is billions of years old, that I'm (partially) breathing products of photosynthesis, that the universe is unimaginably vast, and so on. I'd like to find experiences, practices, places, and reading and other media that can help me internalize and understand more deeply what we actually know to be true. [more inside]
I'm a couple years off finishing a PhD that's been about half biochemistry and half electrophysiology at a top-ranked Australian university. The academic career path is definitely open to me - I've got a decent number of publications, heaps of teaching experience, blah blah blah - but I'm unsure that it's what I want to pursue.

I saw a quote recently, possibly here. It was something like, "the point of being alive is to produce energy to support the creation of more life." It wasn't about procreation but more about how our biological processes exist to create energy for other living things, as part of the ecosystem. Can't remember more of the phrase but I really liked the concept and would love to know more about the quote.

We are working on simple machine language in computer science for data manipulation. All the other problems I have gotten through but this last one. Here is the problem: "Write a short program in machine language to perform requested activity. Assume the program is placed in memory starting at address 00- -If the value stored in memory location 44 is 00, then place the value 01 in memory location 46; otherwise, put the value FF in memory location 46."

What question can I ask undergrad research assistant candidates to see whether they are good at looking things up on their own? [more inside]
Tomasetti and Vogelstein recently published an analysis that suggests the variation in the number of stem cell divisions leads to cancer incidence rates that are higher for tissues with relatively greater numbers of divisions. They recently posted a follow-up which attempts to address some of the counterarguments to their results. Acting on the premise that their work is correct or at least "in the right direction", are there labs or drug companies working on gene therapies that attempt to improve DNA polymerase fidelity (even in model organisms), as a means to one day perhaps reduce cancer incidence in higher-risk tissues? While it is easy through mutagenesis to worsen fidelity rates and increase cancer rates (as has been demo'ed in mice, say) can this aspect be engineered to be improved — that is, what biochemical aspects of (human) DNA polymerase have evolved to control its fidelity rate such that it might be possible to improve upon it?
A young woman (14 years old) of my acquaintance absolutely loves those "fun fact of the day" trivia phone apps. Now I'm looking for some books I could recommend to her chock full of fun facts, and explanations of the background of those facts, that would be age- and knowledge-level-appropriate. Ideas?

I am studying psychology and like to make associations and note similarities between different theories. For example, perhaps I see a relationship between Fromm’s concept of conformity and ideas of enculturation and socialization, from there maybe I can then link to constructs of social interaction in Vygotsy’s work on learning. I believe that I am looking for a non-linear organization system similar to a big mind map, semantic network, or a personal wiki. Any suggestions about how to structure something like this?

Would a human brain be able to make sense of the information? Would the person see anything at all. Or would the person see exactly like the donor animal (very unlikely I'm guessing).
I have a B.Sc in computer science and have one year of experience English using my CELTA qualification. Looking around, I see a lot of requests for people with North American B.Sc's to teach Math/Physics/CS in Asia. I'm trying to decide whether to go and start teaching, or whether it is better to get a state teaching qualification (2yr) in the Netherlands first... [more inside]
Please help me find good quotes about how and why sci-fi is inspired by science, or how science is inspired by sci-fi.
Years ago, I read a short story about two biologists (geneticists?) who are friends. After a global plague that makes all women infertile, one of the geneticists devices a treatment in which women can again reproduce, but they spend their entire nine months of pregnancy with blue, flaking, itchy skin and extreme sickness. The second geneticist realizes that the first has actually devised both the plague and the cure. He asks his friend why he did it. "Because I never wanted another child to be born unwanted," the first geneticist replies. I probably remember some of this imperfectly, but that was the gist of it. Does anyone happen to know the author/title? Thanks in advance!

I'm interested in learning more about the science of mind-body connections, especially in the mind-impacts-body direction. For example, I'm curious about how mental exertion can lead to physical fatigue, or how an emotion can trigger physical symptoms in the body (such as indigestion from stress). I'm looking for an interesting and accessible book on this topic, if one exists. [more inside]

What's current research say about what factors go into making a happy long-term relationship? In particular, I recently heard of some studies suggesting that couples who spend oodles of time together and are basically each other's best friends may be less likely to be happy than couples with separate hobbies, friends, etc. However, I can't seem to actually *find* any of those studies...anyone know of these?

My question is two-fold, really. First, please recommend to me all of your favorite titles on the history of science, math, technology, and medicine.

For a science demonstration at my son's school, I have modified a webcam so it can detect infrared light. I would like to be able to heat up an object (I don't mind what) so that it can be seen on the infrared camera. So far, I have found that I can see a match (even after it has gone out), an IR remote control, and a gas flame. But these are all a bit tricky in the school environment. Ideally, I would have a battery powered device that would heat up a piece of metal enough that it will glow (in the IR) without anyone being able to burn themselves or set light to anything. I don't mind making the device, modifying something, or just buying something.
