If you bothered to go past the Slashdot summary of the arXiv blog summary of the paper's abstract summary, and actually RTFA by Casadio et al., you would find the following:
We can conclude that black holes created at the LHC under the warped brane-world scenario and described according to Ref. [4] would always remain microscopically small in mass and radius when traversing through the Earth.
and also this:
We conclude that, for the RS scenario and black holes described by the metric (6), the growth of black holes to catastrophic size does not seem possible. Nonetheless, it remains true that the expected decay times are much longer (and possibly â 1 sec) than is typically predicted by other models, as was first shown in Ref.[4].
Possibly, potentially, maybe, under certain conditions, they might be longer lived than expected. They still can't grow.
In this comment, and elsewhere in this topic, I notice that you preface your comments with "@parent", to make it clear to whom you are responding.
Unlike most blogs, which are linear in structure, Slashdot uses a nested comment structure. It is already clear which comment you are responding to, based on the physical position & indentation of your comment.
This isn't intended as a flame of any sort, it's just that, curiously, your mid-six digit userid # would suggest that you've been around long enough to know this. Is the @parent preface an ingrained habit from other blog environments?
don't be surprised when a publisher insists you use a Microsoft Word template and turn on document revision control for your chapter submissions.
Probably the most insightful comment in the thread. What YOU want to use or what YOU like is irrelevant. It has to be convenient (or at least workable) for the publisher. If it's not, you will be told to make it workable.
So, which is more work? Writing it in your preferred environment, then transferring/converting it and hoping that it's all there afterwards, or writing it in MS-Word natively?
Bear in mind, the publisher will almost certainly NOT want you to do anything with typesetting (fonts, spacing, kerning, etc.). They will do all of that in-house. All they'll want from you is your deathless prose, typed into a pre-set template, or sent to them as raw text.

Conventional incinerator plants produce a lot of ash and nasty combustion byproducts, like benzene, toluene, etc. This is a result of the incomplete combustion of the trash. Even well controlled, high temperature incinerators have this problem with the stack gases.
Plasma systems reduce everything down to elemental composition. All of the toxic volatile organic compounds (VOCs) get broken down to C, H, N and O. This can be done in a variety of ways, many of them more effective and energy efficient than you might think.
The point of plasma reduction is not that it's going to magically be a net energy producer, but that it's a much cleaner way to recover some energy while you are destroying trash. This would be particularly appropriate for difficult to recycle materials, such as stubborn plastics, components with trace heavy metals, things with toxic coatings, etc.

When the space elevator eventually gets built, passengers are going to need something to protect them from the radiation in the Van Allen Belts. Rather than hauling a bunch of passive shielding up and down, these isomagnetic shields would be pretty useful.
Power would come from the same source that drives the climber (whatever that is...).

If we had the technology to supply these things with the power they need,
Hey, wait a minute! Are you saying these things are... fictional?
Why didn't anybody tell me! My business model is shot! My Step 3 is dependent on these super-dense power supplies! Now I'll never get to Profit!
Well, they were hidden until I let the cat out of the bag. Doh!
I forgot to mention that, as for this being an unproven technology, the Spirit and Opportunity systems did almost exactly the same thing with the retrorockets. They lowered the lander out on a tether + umbilical, then fired rockets to bring it to rest ~40m above the surface. Ground-capture imagery let them adjust thrust to counter lateral movement, so it would drop straight down, without a lot of side momentum. I should say, pretty close to rest... there was still some vertical and lateral movement when they cut the tether.
Granted, they'll need much bigger rockets to slow down 900kg vs. 180kg, but a lot of the 180kg of Spirit and Opportunity was airbag, casing, support stuff. All of MSL will be of instrumental scientific value - a lot more bang for the buck.
The cables allow for some leeway in how hard you can hit the ground and still have a functioning rover. If you come in too fast with a single piece of equipment, the whole thing goes crunch. The rockets and ground acquisition sensors are good, but not perfect.
With the rover on the end of the bridle, this decouples the weight of the scientific payload from the weight of the support equipment needed to ensure a soft landing of the payload. Once the thing is on the ground, you don't need any of the support equipment anymore. You can make the rover tough enough to handle a harder-than-expected landing, even tough enough to bounce a bit. Accelerometers on the rover will send the signal back up the umbilical to give the crane the green light to cut loose and go away. I suppose that you could even have tilt sensors on the rover to tell the crane, "This is a bad place to leave me, pick me up and put me someplace else."
A lot of the weight of the (rover + sky-crane) is up in the crane. This set up will let you have a thinner engineering margin in the crane part, saving weight that can be used for more fuel. As long as the crane can fly, it can take pictures and serve as a supplementary probe.
Why do you think the Bush administration blew up the Twin Towers in the first place?
1. Blow up Twin Towers. 2. Go to war for oil. 3. Use the Twin Towers fire to justify continued research on the chimera of clean nuclear power at some future date, instead of clean renewable energy technologies today. 4. BLANK 5. Profit! From Big Energy i.e. Oil and Nuclear!
The team tested the ability of various objects to hold a charge in a vacuum while being bombarded with plasma...Microscopic arcing was observed at voltages as low as -300 V. This arcing caused solder to explode off of the object.
In my experience, damn near everything shorts out in a plasma field if it will carry a charge.
If you want to deflect the plasma (and thereby use the resultant Lorenz force to thrust your spacecraft), you have to use microsecond pulses of surface charge, not continuous charge like you would get from a weak alpha-emitter. Continuous charge = intact plasma filament = charge lead right back to your surface. Break the filament and you still get the expansion of plasma, with the resultant force transferred to the spacecraft through the magnetic field.

You can be sure this is true by the comments posted to the blog, many of which run, "Hey, instead of trashing the Czech paper, you should conduct your own study and publish counter-results."

Admit it, Word can not hold text more than one chapter in one file. MS Word is simply not-good-enough for anything that is longer than 10 pages.
Not a very creative troll, but what the heck...
I've written documents of 55,000+ words in a single Word file, no sweat. Well, the writing was difficult, but Word 2003 handled it just fine.
Turn off all the extraneous bells and whistles and I have no doubt that Word would be able to handle files of 100,000+ words.

Sucks, but there it is.

What a disappointment. If only there were some kind of material that could withstand the 1200C of near-surface magma, or some means of rapidly extracting the heat so we could use it for generating electricity.
Unfortunately, there's no economic incentive to develop these technologies.
This was one of the few books I didn't bother finishing. After ~100 pages, I'd wasted enough time on it.
