It's an environmental allergy, not an emergency one. If you notice you feel like crap in a certain place (because cats like to lurk there), and subsequently avoid it, that's a win. Not that I necessarily believe that's a good

Power distribution is generally done like that in the "deregulated" states in the US. The electric utilities were technically private entities, though not very free. The same legal framework could be used for other sorts of wires,

Probably?

There have been some recent advances, notably in soil bacteria. For example: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC127570/ (you can also find some more popular accounts if you look around.) We'll

I moved my office to a complex that was supposed to have both cable and DSL internet available. Neither was installed yet so we bought a Clearwire device to fill the gap. The DSL was a slightly better deal, so we had them in to install it,

Many (perhaps most) bacteria are specialized for very specific environments. There's tons of strains that are hard or impossible to cultivate in order to study or measure. http://jb.asm.org/content/194/16&#x2F

I've seen that in use plenty in the US. My water mains were replaced a couple years ago like that. I presume it's not applicable to every situation, though. A place like Manhattan, with lots of connections in a short distance, it

Uh, no. Radiocarbon dating is routinely done on such things as shells, shipwrecks, peat, mud, and groundwater.

The reason his income streams kept blowing up is because they were all basically scams and/or spam exploiting early Internet search and advertising schemes, which in pretty short order either collapsed or got wise. Which is good to see

One factor in the shape of the station that's not commonly known is actually aerodynamics. The ISS is in a rather low orbit (mostly to make getting there easier) so aerodynamic drag is a noticeable (if small) force. The station is thus

The sky is cold, the Earth is warm, and the Sun is hot. If you have heat you want to get rid of (and in a spacecraft you usually do, since vacuum is a great insulator), you put it into a panel with good heat radiation characteristics and po

The reason to have sleek exteriors or to look cool is because you need be aerodynamic (because you're in the air) or need to look cool (because you're in a movie, or you're a consumer good). Being neither in much air nor in a

Trains (which are mostly self driving) have a button the operator must push once in a while to prove he's awake.)

Millions would be great, as it's currently a matter of tens (or hundreds) or millions. Order of magnitude can make a big difference.

And that's a face in a completely different way than I thought when I first looked at it in the original image. Sorry, it's just your (and my) natural pattern-matching misfiring. There's some accidental feature that looks lik

Yes. The generators turn into motors if you turn the electricity around.

At least, those planets of a small enough size to lose water. Jovians probably don't count.

Well, sort of. It takes a lot of free oxygen to overcome all the various reducing agents usually found on planets (iron, hydrogen, aluminum, lithium, silicon, etc). The only process we know of capable of generating a continuous long-term fl

No mere customer will get the Air Force to replace their ancient and crumbling radars, or, moreover, deal with all the various resource contention issues at the Cape. SpaceX is instead in the process of dealing with the problem in a tractab

It's a 2048x2048 pixel camera, and is there mostly to provide context to the other sensors. While better than many historical probes, it is a bit low-res today. But NASA's MRO already has some great optics over Mars, so they proba

No. Cape launches would land back at the Cape.

Brand-sensitivity scales with price and the need for quality. Almost no one will buy an off-brand car, but most people will buy an off-brand cheap plastic toy if the price is better. Action cameras are probably on the low end of that scale,

Two and a half weeks between launches. Pretty good.

It's probably easier. To produce injectable amounts, they'd have to do about the same thing in a bioreactor or another animal and then extract it. Using the target as the bioreactor skips some steps--and assures a nice steady supp

According to the paper, not at all, barring some nicely-pointed flare events. It's a very dim star.

Because it's a web-based book? I've browsed about and haven't seen a clear explanation. (It took a while to figure out what the hell is going on at that site.) Apparently he considers underlining a sin against typography [ ht

Pretty small. You might say: "It's experimental. Might as well make it small so you can put it on a cheap(er) rocket like the Vega." But they seem to want to make a full system (the PRIDE spaceplane) that also flies on the Ve
