+B: I'd be willing to give them some coffee.  The other cool aspect to this is that, if you think about it, space deployments are expensive partly because the objects have to be built to survive the rigours of being launched and it's easy to forget about that, but it makes sense.  These structures have to be constructed to survive that, otherwise if you just send to space a pile of broken parts, I mean obviously not a good move.  This company, Tethers Unlimited, is calling these satellites, they refer to them as a chrysalis or even an embryo.  So what they're going to contain would be stuff like raw material needed in a very compact and durable state so it would be very inexpensive to get it ready.  Just pretty much dump it in there and you're almost ready to go because it would be very hard to damage these things.  And also they talk about including stuff like software DNA instructions because there's so many biological analogies here.  So of course you would need the instructions for actually building these structures using the spider robots.  Orbital construction of course, allows things to be made that dwarf what's possible with today’s systems and not just from a pure physical size, and this was a good quote from the CEO of Tethers Unlimited.  His name is Rob Hoy, he said, "this radically different approach to building space systems will enable us to create antennas and arrays that are tens to hundreds of times larger than are possible now, providing higher power, higher bandwidth, higher resolution and higher sensitivity for a wide range of space missions.  So everything about this is just so out of scale that I'm just so excited to see what this could possibly bring in the next generation or so.  So where are they right now?  So right now it seems like they're in the first phase of the spider fab architecture.  What they're doing, I don't know it's a little sketchy exactly where they are but I think what they're doing is they're constructing things like trusses using robots and 3D-printing.  They call it a trusselator device and a truss is essentially a large support structure and then once you have the support structure down, then you're all set to attach things to it like multi-hundred kilowatt solar arrays, large solar sails and even football field size antennas that they would attach to these trusses.  So the future is looking pretty good for this.  They said that they're not ready for deployment yet obviously, but they don't think they're very far away, and a big help: NASA just gave them a 500,000 dollar infusion of funds.

== Questions and Emails () ==

=== Question #1: Pox Parties () ===
<blockquote>Have you guys ever talked about intentionally infecting kids with chicken pox? As a small child I remember my mother doing this when my childhood friend. She took my brother and I over to play with him and tried to get us infected. My brother broke out, while I only had three actual pockmarks. I never challenged this idea and figured that all parents did this. I mentioned this at work and my co-worker was flabbergast; citing that that was ”a stupid practice”. He went on to say that there is a vaccine for chicken pox and that purposely infecting your child just opens them up to get shingles later.I personally haven’t had a memory this old brought up and challenged. I would like to believe that I am analytical and not subject to wives tales, but I personally never challenged the memory and practice. Maybe you guys could talk about this as I’m sure other have had similar experiences.Thanks,Andrew MartinezRochester, NY</blockquote>

=== Question #2: Aromatherapy () ===
<blockquote>I’m a new fan of the show and a budding skeptic so if this topic has already been covered maybe you can point me in the right direction for some good info.My brother’s wife has recently been selling essential oils and she is absolutely in love with them. Any and all problems you may have can be helped with the use of the proper oil. It sounded a little shady to me so I tried doing some research and I found plenty of people talking about how its a scam but I also seemed to find some studies to back up some small claims of oil users. Nothing earth shattering but maybe some use in helping with headaches, stomachaches, and relaxation.So, I’m asking you guys to help me understand this once and for all. Did I find bogus info? Is there perhaps some small benefit to this? Or is it straight pseudo science and quackery all the way thru.RobertTexas</blockquote>

== Science or Fiction () ==
[http://www.tip.duke.edu/node/1437 Item #1]: A thorough review of published studies in Psychology found that only 5% of published replications confirm the prior results.
[http://www.eurekalert.org/pub_releases/2004-05/bc-prc052604.php Item] [http://phys.org/news/2011-09-statistical-error-large-neuroscience-papers.html #2]: Studies have found that as many as 50% of published peer-reviewed research contains statistical errors, sometimes changing the conclusions of the study. [http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0005738 Item #3]: In surveys, 34% of researchers admitted to questionable research practices themselves, and up to 72% in their colleagues.
