That's not what this article says. Only 3.2% of the orders placed in the stock martket actually go through. That was the second quarter of 2013, well after the 2010 flash crash. And on some exchanges a whopping 99.76% of orders is canceled.
Quote from that link: "High frequency trading firms have been known to flood the market with orders, trying to determine the price institutional or retail investors are offering, then cancel 90% of them a split-second later. This can artificially alter the price of a security, netting high-frequency traders profits at the expense of their counterparties."
Actually, never mind, I just looked it up and it seems that its 24 to 36 protective layers will actually be as hard as concrete and provide better ballistic protection than the rest of the ISS.
I just wonder how it will handle impacts by space debris. The ISS has lots of pits caused by micrometeorites, I hope the inflatable module has some kind of self healing properties when it gets punctured.
Quantum entanglement can be simultaneous for some observers, while connecting two events at different times as seen by some other observer. So quantum entanglement appears to indeed be able to transmit "information" back in time, but this kind of information is not exploitable to send actual information of our choice. Hence, even though the effect is definitely spooky, it does not violate causality. You cannot use it to kill your grandfather in the past, get tomorrow's stock quotes, etc.
No, "CIS" is the Commonwealth of Independent States. Apparently they have started a colony on the moon and now NASA is planning a humanitarian mission. There's a typo in the title.
They transmitted information "instantaneously" between different properties but at the same location. Nothing traveled faster than light. The part about "across multiple locations" is fiction unrelated to this experiment. They even admit that "With this form of teleportation, we can, however, not bridge any given distance".
If two events cannot be causally related in the reference frame of some observer (time difference t, and distance more than t times c), then two different observers may disagree on which of the two happened first. One may say supernova A exploded before B did, another may say that B exploded first, and yet another may say they exploded exactly simultaneously, but it doesn't matter since neither event could have affected (or caused) the other. No information could have traveled from A to B or from B to A in the time between the events, no matter which reference frame you are using, so there's no paradox and everyone is free to disagree on which happened first.
If the events are closer together though, so that a ray of light emitted by A could have traveled to B before B exploded, then there's a causal relationship that will be true for any observer. Nobody will be able to say that B happened before A, the Lorentz transformation will always give the same sign for the time difference no matter what speed the observers are traveling at.
This all breaks down if you can transmit information faster than light. Suppose Ann says A and B happened simultaneously, and Bob says A happened later than B. Now Ann sends information from A to B "instantaneously". From Bob's point of view, the information traveled back in time. So far this is not really a problem yet since A and B are not at the same location, but it gets better. From Bob's point of view, since A happened later than B, B is really simultaneous with some event A' that happened at the same location as A but at an earlier time. Nothing stops Bob from setting up a system that sends the same information from B to A' "instantaneously". Bingo, the information just traveled back in time from A to A', and Ann just received the stock quotes she will send tomorrow.
I'm not saying this is definitely impossible, just that this would be the logical consequence of FTL information. FTL implies traveling back in time.
They didn't figure out "non-local data transmission at FTL speeds".
They figured out local transmission without loss of time, i.e. encoding information into the polarization of a light beam, instantaneously, but without bridging any distance.
Quote: "With this form of teleportation, we can, however, not bridge any given distance," admits Szameit. "On the contrary, classic teleportation only works locally."
The rest is just the usual hyperbole and Star Trek comparisons by people who don't know what they're talking about. "Teleportation works instantly across any distance!" – yes, but not that kind of teleportation. The kind that works across distances cannot be used to transmit information.
So you can send information faster than light, but only if it doesn't actually go to any other place? Send information from A to A instantly? Damn, I knew I should have gotten a patent on that while I still could!
The reason why it's getting slower is because more people are using it. So "getting slower" and "not many people use it" are kind of contradictory.
Because of the constant bickering between the developers, the protocol cannot keep up with the system's growth. Bitcoin was designed to be adaptable, all it takes is a change in the specs (easy) and general agreement among a majority of miners (which is apparently a lot harder). Once they finally agree on which path to take, the system can speed up again in a matter of a few days. Volume can go way up and transaction times can go way down, the current slowness is not due to any inherent flaw in the system but, like you say indeed, because the people in charge are not in charge and can't sort out their shit.
Actually, one of the most important areas of study would precisely be trying to grow plants there. What else are they going to do all day? Make sandcastles? Once they've analyzed the soil, there's not really that much to study. Staying alive, growing stuff and producing energy, those are the things they will be most interested in.
They'll be flying to Mars for 8 months or so. If they just dehydrate their faeces (gotta drink, you know) and keep the dried residue, they'll have plenty of fertilizer once they get there.
Voting for a republican majority in the house with a democratic president, resulting in gridlock, government shutdowns, etc.? Yep, that too was a mistake.

Retrieve sensor data? So those silly science click-fests in Kerbal Space Program are realistic after all?

Well, it's bound to be the first manned flight beyond LEO for as long as anyone currently working at NASA can remember.

Causality really is independent of the observer.
If two events cannot be causally related in the reference frame of some observer (time difference t, and distance more than t times c), then two different observers may disagree on which of the two happened first. One may say supernova A exploded before B did, another may say that B exploded first, and yet another may say they exploded exactly simultaneously, but it doesn't matter since neither event could have affected (or caused) the other.

I can't help but think of this xkcd comic.
Which KSP mod do I have to download for that?

Darn, now you spoiled the trailer for me!

You can grow grass by adding fresh cut tomatoes to the soil.
I don't use Windoze, but if I did, I would be even less likely to update now.
OK, maybe 6, tops.
The incident happened in january 2012. They ought to have had enough time to think it through now...
Did they get a patent on that?
Or just create a new protocol that fixes Bitcoin's flaws. I wonder why nobody has thought of that yet.
