I have a large road case (2.5 / 2.5 / 3 feet) that I need to weigh. It is too big to fit on one scale. Would it work to place one scale under each of the 4 wheels and average the 4 weight readings? My physics-fu is not strong enough to figure this one out on my own. Help!
This Halloween I did some Halloween candy science experiments with my nieces and nephew. One of the experiments we didn't get to do (but soon will) is: Pouring Pop Rocks into a bottle of pop will make all that pent-up carbon dioxide escape but not fizz over. If you put the rocks into a balloon, then fit the balloon over the bottle's mouth and let the rocks fall in, it inflates the balloon with carbon dioxide. But what can I do with a balloon full of carbon dioxide? ...Is it a stupid idea to inhale it to see if I get a funny voice? [more inside]
Researching the human heart for an essay. The real heart. not the metaphorical one. I'm having trouble finding interesting articles online that go beyond 10 FACTS ABOUT THE HEART-type-things that get repetitive. I have already done a good bit of research into transplant history and fetal heart development, and I have a story about NASA growing cardiac cells in a bioreactor. But I still need more! Can you either tell me interesting true stuff or link me to it?
What are some contributions that Canadians have made to meteorology as a science? I'm looking for technologies, theories, whatever you can come up with. Even Canadians that were involved in the development of something to do with a technology or meteorological finding. I've spent most of my evening on Google with little success, yet I'm required to teach this to my students.

I'm slightly obsessed with well-put-together science-y treatments like those done by XKCD's "What If" and ASAPScience. Given this obsession, where are other places I might be able to get my fix? :) (Note: Video is fun, but I'm not opposed to reading, either!) [more inside]
I recently saw a great animated piece expressing exasperation (that I share) with the anti-vaccine, pro-feelgood-pseudoscience crowd. It was from Australia or New Zealand (maybe somewhere in the UK?), it rhymed, it was clever and stylized in a way I want to reference to an artist friend. Ringing any bells for anyone, or have the vaccines rotted your brains, too?

My original proposed topic for a publication I'm writing in was about printing organs and bone marrow but it may be rejected because someone else proposed the same idea.

This seems like it ought to be a simple question but I'm not finding the answer myself. Someone here must already know. I would like to buy sheets of printable adhesive labels suitable for sticking on 1.5ml/2.0ml microcentrifuge tubes. Ideally I would like both dots for the caps and little rectangles for the sides. They don't need to be able to stand up to particularly tough conditions, except that they shouldn't run if they get wet. Also, they should be cheap as I am a grad student and would be buying them out of my own pocket. I am just sick of writing the same teeny tiny letters over and over and over again with an ultrafine Sharpie. Can somebody here point me to a product that I can buy that would suit my needs?

I graduated with a biochem PhD a month or so ago. As is common practice at my institution - my thesis advisor offered me a few months of additional funding to finish up some papers while I hunt for industry jobs. Formally, I now have a post-doc appointment and salary, but I'm not actually taking on any new projects or doing any new science, nor do I have funding to stay her for more than another month or two. How should this look on my resume? I'm only applying to industry positions, not to academic positions or proper post-docs. [more inside]
Imagine you're allowed to give a nobel prize for five of the most seminal books of the past 50-60 years in whatever field you're interested and/or invested in. What would they be? The Nobel is usually given out to applied research and application and theory is eschewed. In this case you can give it to theoretical works as well. [more inside]

There is a concept I remember reading about but can't remember the name of, and none of my flailing Google searches are coming up with anything. Basically it's the concept of... repeatability? Our assumption that the laws of physics remain constant? The notion that if something occurs once, that given the same circumstances it will happen again, eg every time you add vinegar to baking soda it will foam up and after repeating things enough times we can assume that it will always happen- it won't suddenly burst into flames or turn into a radio or whatever. I remember reading that this assumption is both what science is based on and something we can never know for sure, since all it takes is one instance of flammable baking soda and vinegar to disprove it and maybe that'll happen tomorrow. I'm also not 100% sure this is a real scientific concept and not something I read in science fiction. :[
Most machines are very predictable when in motion- their movement can be graphed in terms of speed, acceleration and jerk quite easily. Generally, the graph flattens out when you get to jerk. Can the same be done with humans? Or are our movements chaotic at a fundamental level? I know that ultimately we exert motion through force (=ma) but is it possible for us to increase the rate at which we increase the rate of force, and even increase the rate of that? Would we be able to register anything on the graph of m/s5? [more inside]
I'm looking for two books, one biology, one chemistry. They are related to GCSE, they say that on the front of the books, but I don't know if they're licensed. One has a green cover, one has a blue cover, but they both have pictures on the front. The good thing about these books is that they explain scientific concepts through diagrams in one-pagers, which are conveniently in both Chinese and English. Help me find these books? [more inside]
I'm working on a new book and I need to name a genome. I can't handwave it-- while the book is SF, I don't want people in the know to be able to look at it like people look at Law & Order address (ie, nobody from New York would ever think that's a real address. Nobody in science would ever think that's a real genome.) [more inside]
I work at a Museum and we are about to roll out a new staffing model for our part time staff. Essentially a "career ladder", the program will have four stages of progression starting with general skills (everyone in this stage can float around the Museum providing customer service, essentially). The three subsequent stages add increased specialization, training and skills (employees in stage 4 can lead teach programs like camp, for example). We have a pretty young staff, and are generally a hands-on STEAM (science technology engineering art and math) focused institution. We're looking for creative names for the stages that are descriptive without being too silly. Any thoughts? [more inside]

I'm a research scientist and I sometimes give presentations. Presentations are unique because, while they aren't the most important part of my work, there is a built-in deadline. I can only work on them until the presentation time, and then I won't get another chance to redo that particular presentation. Most other things I can work on until they are done in the order of what is most important. But giving a good presentation is still pretty important. So when I have a presentation coming up it is hard to decide what to work on first. If I work mainly on the presentation then I feel like I am postponing my important regular research, which isn't great. If I work mainly on the research, then I feel like I am resigning myself to giving a more mediocre presentation, which isn't great either—it makes it less likely that people will understand the work and isn't good for my reputation generally. If I try to switch back and forth I lose concentration and energy due to the difficulty of context switching. Do you have suggestions for how to set priorities in this scenario or what has worked for you?
I want to write an article explaining where to find scientific information and how to evaluate scientific research. Which quality sources and articles would you recommend that I recommend? Please suggest material that has helped you become a better researcher. Which resources have helped you weed out the pseudoscience and poor quality information? How do you determine which journals have a high standard and which are either predatory or providers of disinformation? Which forums and communities do you use when working on problems above your knowledge paygrade? If you were to design an ideal skeptic's handbook for finding and evaluating research, what would you add?

K, so I've found out through researching this that the water can come out at 200mph, but does anyone know how much pressure the water comes out at? (I've done a fair amount of research on it, but have only found the 200mph bit out. Was hoping I might get some help from the hive.)
We've had PG&E SmartMeters installed at our building for awhile, and our landlord is very concerned about the health risks and surveillance risks he believes they pose. He's sent us a bunch of "literature" to read and it all reads like wackadoodle conspiracy theories with no basis in science, as does everything else I've found online. As easy as it is to just roll my eyes and dismiss his concerns, I feel like I should make a good faith attempt to discover if there's really anything to be concerned about. Are there any good, reality-based reasons to be anti-SmartMeter? Any science-based studies from reliable sources on their safety? Any well-thought-out articles on the subject that don't include the phrases "molecular earthquakes" or "like hundreds of cell phones being on at the same time"? Help a skeptic out!

Somewhere in the last two to five years, I read about a study where a group of women (I believe the women were Asian, possibly Vietnamese or Thai) were given meals that were: (1) either beautifully and colorfully presented, or (2) pureed into a gray mush. The meals had exactly the same nutritional content, but the women receiving the colorful meal absorbed more nutrients. But I can't find any articles or the study itself. I've been Googling up a storm and still nothin'. Anyone remember this, or articles about this? Help me please?
I'm trying to remember the name and author fo a sci-fi novel that predicted the idea of Google glasses and their impact on society. I can clearly remember one of the characters, a youung person, complaining that all these old people had these glasses that recorded everything that happened around them and could send that data directly to the police. It was kind of an Orwellian Big Brother feel to society. You were always being watched, recorded, reported, etc. I was reminded again about this after reading an article on NPR about the first police arrest recorded on Google Glass. Does anyone else remember this book or the author? Thanks in advance for the help.
