You're mistaking upstream and downstream purification. The products you cite are used to purify water before it is delivered to homes. Naturally this water needs to be very, very clean, and so anything the size of a microbead would, in fact, be filtered out. However, the systems in place to clean sewage and grey water…

In addition to debunking your favorite Twitter targets, will you also be pointing out errors in Gawker Media blog posts?

I spent years vaccinating mice that always tried to bite me, to get my PhD when I could have been hassling Brazilian seahorses instead? Clearly I have made some poor life choices.

If we're FWIW-ing, I have a PhD in Microbiology and am currently working with our hospital's Infectious Diseases consult team.

Good for a 15 year old for building one, but there's absolutely nothing new about it as far as I can tell. Shoe-based chargers are nothing new. The military has been interested in them for years, and a quick Google search turns up scads of projects, some dating back to the 90s, using this exact same technology. There…

I'm not saying there aren't issues with them. I'm just saying the fact that they lyse bacteria isn't a reason to dismiss them, which is how I read your initial comment.

About half of the antibiotics we currently use end up lysing the bacteria too. Which is not to say that it's not a problem, but it certainly wouldn't be a contraindication to using phage therapy in the general population; you'd already be taking those factors into account in your choice of antibiotics.

Western use of phage therapy pops up as news articles every so often, and has for decades. There's a serious dearth of good clinical trials, though. Without those it's pretty hard to take seriously any of the wonder-claims about efficacious they really are. I'm all for new therapies, but they need to actually prove…

Who says people wouldn't do that with phages too?

As the artist himself says, it's a labyrinth, not a maze. There's only one route through it, it looks like.

Maybe for the Delta IV Heavy, but the Medium, (the one directly comparable to the Atlas V) is equivalent of only slightly more expensive than an Atlas, at around $150 million per launch. Too expensive for the commercial market, yes, but nowhere near your "half a billion" figure, and not about to exactly bankrupt the…

CT scans are very quick, just a few minutes (the scan itself only takes about 20 seconds). A really, really simple MRI you could probably do in 5-10 min if you had a very specific, easily diagnosable finding you were looking for that only needed one mode, but usually you're looking at a bunch of angles, different…

That doesn't work either. You can't really take 10 pictures with 10mm resolution and combine them into 1 picture with 1mm resolution. The information at that smaller resolution just isn't there.

Pretty impressive if GE is coming out with a 7T commercial model, but I was just working with some neurologists who had seen scans from a 14T research MRI, and they were almost frightened at the level detail.

No, it's a physical limit based on the size of the voxel the MRI captures. You'd need some CSI style "enhancement" to get any better resolution from software alone.

So brief, so cutting! You might have wanted to take some of that time you saved to read any of the 70+ other people who said the same thing, only to find out that when I wrote that post the word stateside wasn't there. In fact, the author of the article even thanked me for pointing out the error, and said he'd correct…

Still a better outcome that some deliveries by Amazon I've heard of.

While a nice idea, "everything needed" does not really exist. For the cable, everyone says "carbon nanotubes", except that no one has ever made one longer than a meter, and you'd need ones tens of thousands of kilometers long.

Yes, because fuel depots are renown for surviving high explosives...

A huge amount of fuel is consumed by generators at forward bases, not vehicles. That's energy that can be replaced by solar/wind/efficiency, etc... Less fuel used —> fewer convoys —> fewer deaths.
