The two lakes are basically on the Canadian shield. There was already a stream running between the two of them. The resort has been operating this turbine for tens of years with no significant change to the lake levels.
I suppose it's possible that the turbine may have decreased the flow rate of the stream.
I agree on the micro-hydro setups. This winter I stayed at a resort in northern Ontario that has a 20kW turbine on site. It's the only electricity that's available there. Privately owned and maintained.
Little-to-no damage to the habitat, because the resort is situated between two lakes that have a level difference of about 6 feet naturally.
Of course, it's rare to find locations like that where low-impact turbines could be installed, but we should capitalize on them whenever we can.
True story - I once convinced my coworker that gullible was not in the dictionary. She pulled out a very old dictionary, and proceeded to look it up, only to find that, no, it was not in there as a separate entry.
After I bit of digging, I did eventually find it as a conjugation of the verb "gull," meaning "to deceive."
Evolutionary theory does not make any claims about abiogenesis - the origins of life itself. It merely makes claims about the change in the forms of life over time. The combination of inorganic compounds into organic building blocks, and the combination of those building blocks into the first living cell, these are both outside the realm of evolution.
Bacterium genes are spliced into vegetables as one of the most common forms of GMO crops. In general, it's not unusual for genes to be lifted from one genome and inserted into another that would be vanishingly improbable to happen in the wild.
I won't say "impossible" because some genes are thought to have been transferred between species through viruses, but it's a very very rare occurrence.
I'll also head this off and say that I'm not philosophically opposed to genetic manipulation of foodstuffs.

Seriously, there's hundreds and hundreds of hours of television and movies on Netflix that is of comprable if not higher quality than what the networks are currently showing. All for the price of a single fast-food lunch.
Would someone _please_ make full-wave rectifiers for all of those damn LED xmas lights? The 60Hz flicker in my peripheral vision is almost painful to watch. C'mon, manufacturers, we're talking about 5 cents worth of components here.
Ah. Further reading at the MIT site indicates that they are reading at "1THz line rate". They use a varying electric field inside the camera slit to deflect the photons by different amounts onto a 2-D image sensor. Thus, on the sensor, the x-direction contains spatial information, and the y-direction contains temporal information.
They can do this by sweeping the strength of the electric field inside the streak camera's slit quickly. Photons arriving at different times are deflected by different amounts, and thus hit different pixels in the 2-D sensor behind the slit.
In order to resolve spatial location of the light pulse, at the very least they need to have a sensor with a response time on the order of 1ps. Being able to control the exposure time accurately with ps resolution is also a pretty incredible feat.
They have definitely admitted that they're not capturing the entire 2-d image at 1T fps. They might be capturing a 500-pix line at 1THz line rate, but that's unclear in the article and the video.
This is indeed correct. Radiation hard electronics are created at the microchip layout and design level, rather than with external shielding. It requires an understanding of the damage that occurs from ionizing radiation and high-energy particles, and implementing device layouts that are tolerant of that damage.
Let me give you a little hint: current generation designs with tiny FETs and low voltage drivers cannot operate for very long when the gate Vts start to shift.
If, by "don't degrade quickly" you mean "don't degrade," then you're correct. A local science/technology museum has a (resin-coated) core sample of an old landfill, which has a perfectly recognizable 50 year old head of lettuce about halfway down it.
I actually use both a home composter _and_ my city's curbside food scraps collection (called the "green bin"). The reason is that the green bin will accept a much broader range of materials, because they are ground up and hot composted.
All vegetable matter goes into my home composter, but bones, fat, tissues, paper towels, and pet waste go in the green bin. Between composting, green bin, and recycling, I'll sometimes go 3-4 weeks without bothering to take my garbage to the curb, because the bin just isn't full.
I'm pretty sure that neutrino flavour oscillations (which have been observed - taus changing into muons and electrons) are only explainable within the current frame of particle physics if they do have mass.

In my opinion, the killer app for this is connection to ceiling-mounted projectors. Not only is it a pain in the ass to find a long video cable to connect a computer to a ceiling mounted projector, you also end up with an unsightly cable running up your wall and across your ceiling. Now there's a reasonable solution for media PC's etc.

A company's purpose is not to make the best possible solution ever regardless of the roadblocks in the way. A company's purpose is to create profits for its shareholders. If the cost of implementing the superior solution is higher than the rewards of doing it, a responsible company will _not_ pursue it.

Heh. Classes of infinity. There are infinite natural numbers (1, 2, 3, . . . ). There are infinite integers ( . . . -2, -1, 0, 1, 2, . . . ). But they are both countable. We can say that there are the same number of natural numbers as there are integers. In fact, because you can map natural numbers onto integers (1/1, 1/2, 2/2, 1/3, 2/3, 3/3, . . . ) the sets are the same size. There are infinite irrational numbers too, but there's more of 'em:)
You could potentially use big trawling nets of this stuff to sieve the oil out of the gulf, just like fishermen use trawling nets to sieve fish out of the water. Scoop up a big bucket of oil+water, wait for the water to drain out, then pour the oil into a reservoir on the boat. Repeat.
Deuterium is a stable isotope of hydrogen, and often used in small doses as a tracer in human medical applications.
Tritium is a beta-emitter, with a half-life of over 12 years. The beta particles can cause cellular & DNA damage in living tissue, but it can be stopped by a few millimetres of aluminum.

Nitpicking here:
