If I remember my physchem correctly, microwave ovens are also tuned to an overtone vibration of water (wavelength ~11cm?). The specific frequency vibrationally excites water molecules, which lose the energy as heat.
I think perhaps you may have become confused with Lake Nyos in Cameroon. The blanket of up to one cubic kilometre of gas (mostly CO2) ensuing from sudden outgassing of the lake rolled down two valleys and suffocated everything it encountered.
Depends how you define "crap". It's always going to be a particularly subjective call, but arguably there is much more 'manufactured' music today than in the day of the Beatles. Not to say that it's all crap, but seriously, that Ketchup song? Crazy frog? Probably not going to remembered for their artistic value.
Personally I find the often hilariously awful 'Crunk' genre and whole swathes of pop-hop lacking musicality, but that is only my opinion.
There is an immediate, short term effect - as soon as the subject sees the mast, or suspects that one may be transmitting nearby, they exhibit a physiological response (increased blood pressure, perspiration). As soon as they are sure that they aren't being irradiated by the evil, brain atrophy inducing rays, they return to normal. Long term effects are likely those induced by consistently elevated stress levels: heart failure, stroke (?) etc.
The study demonstrates that the subjects could not accurately determine whether or not the source was transmitting, but also that the presence of such sources can have a damaging effect on individuals inclined to paranoia[1].
[1] possibly strong wording, but my brain can't come up with an appropriate synonym. I blame the cell tower I can see from my window.
Carbon nanotubes are cited in the article as having excellent electron transport properties. In organic photovoltaic devices, charge separation and efficient electron (and hole) transport are desirable properties. Perhaps if the nanotubes do have these properties then the researchers should investigate them?
You go to the record/video store with a particular album/film in mind? I much prefer to have a look and see what treasures reveal themselves.
It's likely that legal downloads will make up a significant proportion of purchases of film/music products in the future, but the stores themselves won't necessarily die.
Lawyers for all the men have insisted their clients did nothing illegal
Forging death certificates? Supplying stolen, possibly diseased, human tissue to medical facilities, which presumably are going to give it to patients who are already ill? And they argue that there's nothing illegal about this? The lawyers themselves should almost be on trial.
In Queensland (I'm not sure about other parts of Aussie), the only legally accepted method of killing these pests is by catching them and putting them in the freezer. Golf, cricket, rugby or any other "sporting" (or not as the case may be) method of disposing of the cane toads is actually in violation of state legislation.
The frozen toads may, however, be used as curling stones.
I remember reading that it was being mooted to use the same stuff to remove organic (as in chemistry) pollutants from the air. It's photocatalytically active, can form very thin films, and has interesting optical properties, hence its use as a pigment in paints.
People said the same thing about lasers when they were invented in the 1960s: "A solution without a problem". But look at us now - where would we be without them?
...there are no atmospheric effects such as seeing. The atmosphere is especially problematic for an infrared telescope such as the JWST, as a significant portion of the infrared spectrum is absorbed by the earth's atmosphere.
While the launch slip will help NASA avoid big cash infusions on the program in the near term, Geithner conceded it will not save money in the long term. In fact, he said, about half of the $1 billion in cost growth is now attributable to the two-year delay.
They admit the total cost will be greater, but as funding is dished out on an annual (? periodic) basis, NASA can spread out the slice of funds that the JWST will take over a couple of funding rounds, so that the impact on other projects is lessened.
A good example of a molecular motor is ATP-synthase, a naturally occurring enzyme in photosynthetic plants and bacteria. It is driven by a pH gradient formed due to the splitting of water and charge separation actions of the photosystems, although it can be forced to operate in reverse, by supplying an excess of ATP.
The enzyme itself is elegant, consisting of a rotating and a stationary segment, and has been the subject of much research by scientists eager to replicate its 'mechanics' into a synthetic cargo-carrying molecular machine, similar to those discussed in the article. Unfortunately, the last I heard imitating nature was proving a lot more difficult than expected.
1) Start a company in a country founded on the principles of freedom of speech.
2) Develop technology to block legitimate use of software.
3) Sell to a government eager to control its people, using the vague pretense of trying to protect a different company's interests to legitimise the transaction. It helps if you ignore item 1) here.
You could, but that's a different problem. AIDS (autoimmune deficiency syndrome) is not a virus, it is a condition that develops as a result of an HIV infection.
I first heard that water may be a greater contributor to global warming than carbon dioxide from Dr Henrik Kjaergaard, in my first year physical chemistry course.
Absorption and reemission in the IR wavelength range (700nm to ~1mm) is important, but so too is absorption at shorter wavelengths, which may be reemitted in the infrared.
Dr Kjaergaard's research group conducts computational experiments and employs long path length absorption spectroscopic techniques to investigate the EM absorption of weakly bound complexes of water in the atmosphere, such as the water dimer.

Also, *technically* an acronym is an abbreviation that is pronounced as a word, such as NASA. Thus DVD is not an acronym at all, but an abbreviation.
Yes, because the Beatles were independent and recorded their best albums in a home studio.
They're trying to beat Apple at making Apple's product look better!

The sound being picked up is not carried by air - it is the vibrations caused by the escaping air transmitted through the spacecraft itself.

I'm anti nuclear-spin. Damned angular momentum!

Actually, it's "laser", an acronym for Light Amplification by Stimulated Emission of Radiation.

A subtle distinction, but an important one.
Close, try a medical dictionary.

I first heard that water may be a greater contributor to global warming than carbon dioxide from Dr Henrik Kjaergaard, in my first year physical chemistry course.
Here is the atmospheric absorption spectrum, the solar black-body spectrum, and the earth's own emission spectrum (which shows which wavelengths are reabsorbed - "Greenhouse")
Absorption and reemission in the IR wavelength range (700nm to ~1mm) is important, but so too is absorption at shorter wavelengths, which may be reemitted in the infrared.
Dr Kjaergaard's research group conducts computational experiments and employs long path length absorption spectroscopic techniques to investigate the EM absorption of weakly bound complexes of water in the atmosphere, such as the water dimer.
:) In Windows maybe - too funky for it to handle.
On any other machine it'd probably open up one of those trippy visualisations.
