An asteroid is a somewhat historical term. A meteoroid is a sand- to boulder-sized particle of debris in the Solar System. The visible path of a meteoroid that enters Earth's (or another body's) atmosphere is called a meteor, or colloquially a shooting star or falling star. If a meteoroid reaches the ground and survives impact, then it is called a meteorite.
Interestingly enough, no designation exists for an asteroid that reaches the ground and survives impact.
No, no hoax. In the water, this kind of propulsion works fine. In the air, however, the rotating speed needed to push against sufficient amounts of air to yield usable lift is insane, and so is the stress on the blades- so it is a question of fabricating it from the right material.
I can assure you; the very instant the right material for constructing this becomes accessible, it goes to mass production.
What you colloquially refer to as "whirlydoodles" is a rotor that carries blades, which in turn can differentiate their angle on attack against the fluid yielding variable amounts of thrust.
Remember how iTunes and Quicktime swiftly tried to take over windows boxes, installing themselves all over and upgrading again and again and again? You seriously think Microsoft will now pass on such a unique opportunity to "gather user data"?
You be trollin'. I am definately not in the mood of advocating Ubuntu, but;
They are working on it, AND they are giving out 2GB for free, AND if you skip the autosync features you can open a crapload of different accounts, AND you get 20GB more for the price of two icecreams per month.
Granted, $36/year may give you a sour face, but have you seen the prices of the competitors?
I thought the Muslims were already pissed that he was dumped at sea
You thought wrong. And you are confusing "thems Muslims" with Bin Laden's followers. Unless of course you genuinely think that all Muslims are Bin Laden's followers, in which case there is probably not much hope left for you.
It is plausible that there will be several short-term benefits for Greece if it bails out from the eurozone- most people will appear to become richer for a couple of weeks or months, but that will be all. But there are two main issues with it;
Issue one is that the lack of production and exports, and the persistent motive in the Greek collective subconcious to become an early-retired, irresponsible, insensitive and indifferent fat-paycheck public sector employee under a nebulous government department that demands to get paid for doing nothing at everybody else's expense, will in the (not so long) longrun reset Greece to the way it is today, with the added difference that it will be not be part of the eurozone anymore. So international credibility will go down even further
Issue two is that at least in people's minds, failed Greece = failed eurozone; so fingers can be pointed at the credibility of the eurozone and the euro in general, and the EU does not want that- "bailing out" Greece is the lesser of two evils.
Final point; IMHO the only way is a halfway meeting between authorities and people; authorities should not lend out blindly, on the hopes of making a quick buck, and should not put together countries like Germany and Romania demanding that they stay on the same pace (and acting surprised when they do not). People should be educated, act responsibly in their jobs and not try to make a quick buck out of other people and from authorities (and act surprised when their dodgy plan collapses).
It has, but Greece (mentioned in your linked article) cannot follow Iceland's example without dumping the euro; as long as it is its national currency, Greece does not get to inflate it or tweak any other of its parameters. Plus Greece has next to nothing production and exports, so not much of value there either. Take the euro and the EU credibility away, and there will be nobody willing to invest in Greece.
Was it a scientific article behind subscription I would consider it, yet I would still complain about it not being on an open-access journal.
I have read enough 'scientific breakthroughs' from clueless journalists to be sufficiently annoyed. Seriously, Slashdot, stop supporting this paywall already.
Pit it against evolution - can it occur naturally?

Biological Lasers
·
· Score: 2
So, towards engineering a shark with lasers, it seems that one needs:
(a) this "GFP" protein as a gain medium,
(b) mirrors,
(c) this "blue light" to bathe it in, and
(d) some sort of lens(?)
what is interesting, it is that all of the above components can easily be made by nature. GFP is already there, the "blue light" could come from a similar process, lenses are in eyes so I would guess (b) could be the hardest one to come up with, but there are numerous animals with a silver-ish tint (reflective surface) plus several wasp species that have so much metal in their stings (deposited there trace by trace from their diet) that they can easily drill into seeds. Point being that reflective (i.e. metal) components can be intermingled and arrayed into living tissue.
I keep wondering as to what could be the chances of such a "laser organ" evolving naturally? Can the fact that it hasn't be seen as a hint that evolution does not have a plan, and is merely a sum of random events? And let's speculate even further- what use could such an organ have?

Flora = plants = photosynthesis = requires light. Maybe you should read the link I posted. Cite otherwise, or shut up.
You cannot be serious.
You sound almost sad for not seeing the green light on new ways of killing people.

I have absolutely no idea how this thing works.
It is a scaled-up (power-wise) version of this.

So fucking what?
It's not Apple pushing the update...
Just this once it is not.

TFA reads monkey, not ape.
Kegs?
does the rocket care as long as mass is roughly similar?
It does not, but the developing team does. Different payloads place different acceleration limits.
Why the hell would I want to read Sarah Palin's inbox? I am already convinced she is up to no good.
You don't get it, it has to be a car analogy. Like so;
Instead of keep patching up your car, get one that was built to last.

Delicious.
Ubuntu One, but the server-side is proprietary. And it is rather buggy on other platforms.

it will just blend in to the bottom as flora start to grow over it
Flora? In the bottom of the ocean? I think not.
