Per capita power consumption is considerably less in most of the world than it is in the US.
The Russian average is about 850 W / person, and a remote northern village is probably going to have lower electricity consumption and higher heating demand than the Russian average. 140 MW of electricity + extra heat for 100,000 people isn't unreasonable.
It's a contrast agent. It's also not likely that neuroscience studies are going to be using it routinely. The iron nanoparticles by themselves are very useful as a contrast agent but there are safety concerns so they aren't used much unless there's a medical benefit. Even standard MR contrast agents are becoming very difficult to use in healthy people.
Still, this contrast agent is likely to be very useful for animal research, if they can speed up the response so it offers practical benefits over standard fMRI.
As soon as ASICs become available. The big operations won't dump their GPUs while they're still profitable, but as soon as ASICs raise the competitive bar, to ebay they'll go.
What seems to have been done is precisely the right way to do it. You use a high-ish specificity test like DNA marker analysis to screen potential matches (that screening pool is way less than 7.6 billion, by the way), then narrow the resulting pool using other evidence, including more precise DNA comparisons once you have probable cause to get a sample from the suspect himself.
Now that sequencing is so cheap, there's really no reason to use a handful of markers to compare, at least not for the actual prosecution.
Most of the arguments here seem to be along the lines of "cops are lazy and courts are dumb so DNA evidence is bad." Perhaps improving the quality of the justice system would be better than railing against a useful technology?
Presumably they used the familial matches to get probable cause to compel an actual sample from the man himself.
There's a legitimate Facebook-style privacy concern in that the actions of my family members can provide personal information about me, but unless California has some pretty crazy laws regarding obtaining DNA from suspects and admissibility in court, there shouldn't be any complaints on that end.
NASA is making a strategic investment, exactly in line with their mandate.
In the first round SpaceX had cool technology and lower costs, but was untested. This round SpaceX is a much better bet, and Dream Chaser is the one with cool new technology that's untested.
Presumably NASA is keeping Orbital ATK around for a bit longer to maintain a choice of two reliable suppliers.
It's a reasonable comparison. NASA needs to get cargo to the ISS. SpaceX and Orbital ATK both have systems to do that.
The SpaceX system can also do things like bring stuff back, and that's kind of nice on occasion, but not really what NASA needs most of the time. SpaceX will also be able to transport people (they can't right now), which I'm sure is of great interest to NASA.
SpaceX can do the present job cheaper than the competition, so they win the short-term analysis. They're also ploughing their profits into R&D and certification which will allow them to do other important jobs in the future, so they do even better in the longer-term calculus.
I technically work for the government (publicly funded science). The competition is cutthroat and there's no money. Necessity is the mother of invention.
I also consult for industry. They have lots of meetings, procedures, management, administration and stupid amounts of money. Stuff gets done slower and much more expensively.
There certainly are sectors of government that are as you describe, but there are lots that are the opposite. And, as the OP was pointing out, when there's insufficient competition in the private sector, they're worse.
You'd think. And yet a Slashdotter managed to make a snide remark about the way people use "natural" as a synonym for "good" AND implied that fossil fuels aren't natural (because they're "bad", presumably), in the same sentence!
Natural gas was called that long before "natural" came to mean "good" to hippies.
It's called that because it is, well, naturally occurring and seeps out of the ground in gaseous form. The Chinese were capturing it and piping it around for heating stuff up in 500 BC.
It's also a fossil fuel. Virtually all fossil fuels are naturally occurring.
"Please cite at least one peer-reviewed, scientific study that demonstrates CO2 greenhouse gas effect."
That's going to be tough. The reflectivity of CO2 to infrared, and thus the greenhouse effect, was discovered a long time ago, so you'd have to go quite a ways back. It's a pretty common high school science fair experiment though, so you could check out one of those.
As someone who has to operate in compliance with the privacy act, I can assure you it is not laughable, and is definitely a law, in the strict sense. Clearly you're aware of this, since you used the proper name, with capitalization, "Privacy Act."
It depends on what the off brand battery actually is. Zinc-carbon batteries are very cheap and easy to make but they have lower capacity and leak when they get old.
I understand that. My point is that when he makes jumps as I described, he's inviting people to assume there's a reason. Presumably Linux has influence over the version numbering.
If you go from 4.9 to 5.0, that's just a.1 bump. If you go from 4.17 to 5.0, it implies there's a reason why you changed the big number instead of the little one.
All the hoo ha about backdoors does seem pretty suspicious. It's pretty trivial to write an app that stores things or communicates with unbreakable encryption and is pretty much immune to legislation. Surely smart criminals must do this already. So a backdoor would only be useful for catching dumb ones. Perhaps insisting that a backdoor is needed but does not exist is useful for catching dumb criminals AND not-so-smart ones.
You're correct. The paper is about a cell culture model for Alzheimer's. The authors point out that lots of potential treatments seem to work on mouse models but fail miserably in humans. So they created a cell culture model using stem-cell derived human neurons. They show that neurons that express ApoE4 have various Alzheimer's-like features, and that these can be reversed by gene editing to flip the ApoE4 to another variant, or through the use of a structure-correcting drug.
The paper is really about the cell culture model, which is very important, but it's not a new drug, and it's a long way from being an actual human.

Selling ads is probably the biggest occupation of quantitative social psychologists.
That's true if you're using a (good) dish. If you're using something like an updated Iridium handset antenna, it's pretty susceptible to jamming.

You can use as big a bore as you want. I've seen demonstrations of MRI done in the Earth's magnetic field.
The tradeoff is between image quality, bore geometry, and cost. With cost usually having an exponential relationship to the other two.

The shuttle was the US Air Force way. As originally conceived it was a lot smaller and more practical, but the USAF had certain special requirements.

Canada has pretty strong privacy laws. It may be your responsibility to delete and possibly report protected data that have come into your possession.

Fair enough, but the jump between .17 and .0 seems odd unless there's some reason. Why not .18? Or .9 to .0 like everyone used to do it?
