    Some years ago someone was asking for something similar on a LUG mailing list. She wanted a mains plug, with the live and neutral connected to various pins of an RJ45. For the obvious reasons.

    By their own criteria of ionospheric behaviour, they'd probably also have had to "predict" a major earthquake in this area around January 25th. Not good enough for a practical earthquake prediction method - but it's an interesting approach. And they do admit to the difficulty of distinguishing localised effects they're looking for from variable global effects from "space weather", so they're being rational.

    HOWEVER, whoever wrote TFS has added other crap to an interesting paper. :

    This is theorized to be the Lithosphere-Atmosphere-Ionosphere Coupling mechanism that occurs when large amounts of radon are released due to massive stress in the fault right before the quake. This can be detected with satellites analyzing infrared waves: 'The radioactivity from this gas ionizes the air on a large scale and this has a number of knock on effects.

    The obvious knock-on effect would be alarming readings at radiation monitors all over the area. In particular - to restate an old nuclear industry story - workers at places like Fukushima nuclear plant may well have set off alarms going into the plant for work. The evidence for this large amount of radon is ... ?

    But hey, I just have to work with much simpler sensor systems in a not-much-simpler non-engineered system. I often know what my sensors are saying, but it takes a lot of thinking to work out what is causing those readings, for any non-standard situation. What would I know about the difference between readings and interpretations?

    Very helpful. I remember seeing so much shouting that "this is a Japanese internal matter ; you foreigners get out of here - it's none of your business! We deny that anyone outside Japan has any right to know what has happened here!" And as for your "resources from around the world" ... I assume that you donated your single-ended teleportation beam system so that resources could be magically transported from (say) Ulan Bataar to Fukushima, without having to worry about traversing roads, finding landing sites for helicopters, and little things like that.

    Oh, BTW, I do recall that within a couple of days helicopter loads of boron-rich reactor-kill material were being shipped from a US military vessel in the area (now why does the Japanese Navy not have their own nuclear-powered aircraft carriers? Oh, nothing to do with Hiroshima, Nagasaki, and them adhering to their own Constitution.). Which appears to have been useful, if not completely effective. Did you teleport in a few more tonnes of boric acid from your own stocks too?

    Bollocks.

    I read TFA instead of TFS. TFA(bstract) specifically contradicts what TFS says :

    Here we show that specific metabolic stimuli enable the killing of both Gram-negative (Escherichia coli) and Gram-positive (Staphylococcus aureus) persisters with aminoglycosides.

    They then go on to discuss the aparrent mode of action as not being relevant to growth issues (and therefore not necessarily limited to antibiotics which interfere with bacterial cell wall growth). Which kind-of blows my argument out of the water.

    Bloody misleading summary though. Sure, TB is a rapidly worsening problem (I've had to be tested a half-dozen times because of suspected exposures), but TFA says nothing about TB.

    How exactly can this technique be used to fight tuberculosis, which lives in the lungs?

    The summary says they've been working on staph (Staphyllococcus) bacteria, which are very different to the Mycobacterium tuberculosis causative organism of tuberculosis. Staphyllococcus is a Gram-positive bacterium ; M.tuberculosis is Gram-negative ; the Gram stain adheres to some components of the wall of a bacterium and so the reaction of a bacterium to the Gram stain divides the bacterial world into a small number of classes on the basis of their cell wall chemistry. Staphyllococcus and M.tuberculosis have very different wall chemistries, and so are likely to have substantially different internal chemistries.

    What's not said in TFS is that many antibiotics act by screwing with the bacterium's wall chemistry, particularly the bits that allow it to grow and divide. Which is probably why this "give it food AND poison" technique appears to have promise.

    But as such, it holds out no direct hope for addressing your concern. Sorry.

    (Having said that, using different antibiotics that target Gram-negative bacteria with this technique would probably be an attractive research prospect now. But TFS says nothing about that.)

There are Islamic prohibitions on men looking at other men's women ; there may be Islamic prohibitions on women looking at men other than their owners ; but I haven't heard of a prohibition on Islamic women looking at other women.

    huge chunks of several-thousand-degrees-hot metal hanging tens of meters above the ground

    Errr, hang on. I don't think that's right. It's certainly not how I'd design such a plant.

    Firstly, you'd obviously design your layout to keep things as close to the ground as possible. Choose sites with equator-facing hillsides, that sort of thing. Simple site selection can save large chunks of cost in construction and maintenance. Only a fool would design for increased costs.

    Secondly, while undoubtedly you'd design your plant to get as hot as feasible - Carnot cycle, all that thermodynamics jazz - you'd not design it to get any hotter than you need to. Again, costs will go up the hotter things get - you need more exotic materials in your pipework, in your working-fluid tanks, it gets harder to start-up and shut down the system.

    Just because you can build solar mirror systems that can turn steel into plasma doesn't mean that is what you'd actually do in practice. Since you're going to need some form of active mirror steering to handle the diurnal motion of the sun across the sky, then you can choose how precisely you focus the light. In fact, you'd probably have to take steps in the controlling software to carefully avoid overheating your pipework.

    A for-instance : this paper discusses alternatives to cryolite as a solvent for aluminium manufacture, looking at mixtures like LiCl and KCl : "a quasibinary system by keeping the amount of LiCl and KC1 in the mixture always in the eutectic proportion of LiCl (58.5 mol %) and KC1 (41.5 mol %) (mp 634 K)".
