They expect to obtain milligrams of matter from space. Which is quite alot, enough to do a wide array of chemistry/ physics studies. One researcher mentioned that it would be enough material to study for 100 years, complete BS.
If I recall correctly they want to use it learn about the "birth" of stars. I think there is other interest, at least to me, in knowing what is in otherwise empty space.
I don't know numbers, and thus probably should keep quiet. But I do know that malaria is considered of the most costly diseases in the world and one of the largest killers. I read recently, probably related to/. , that malaria is being considered as a significant brake on economic growth in tropical regions.
Normally nobody reads the science articles and those of us who do lament the lack of interest in hard science. Occasionally one gets posted to the front page and it seems worse to me.
Among the few intelligent comments are a bunch of wack-job arm chair physicists questioning a preliminary draft of a paper. Just because you read the expansion of the universe is unexplained does not justify linking this research to it. Not to mention the inncesant references to flying cars! Honestly, flying cars? Why does every article about subatomic particles/ forces require invocation of some futuristic fantasy?
And one last rant, referring Popular Science in the context of a legitimate scientific paper, that's a paddlin'.
You can tell its a science by the -ology at the end
I know there a good number of physics people out there, so here goes. .
Other than perhaps Plutonium and Neptunium, have any of the transuranium elements been at all useful? I ask not because I think this research is pointless (on the contrary as a chemist I think it is valuable toward understanding nuclear forces) but I expect any application would be rather novel and interesting.
This struck me as very profound. While not nescesarily correct, though I see no problem with it, I feel as if Marx has just risen up from the grave and smacked me in the face. Socialism comes AFTER capitalism, and the web seems to be the pathway for the transition through its strong equalizing effects. I may be wrong as my Marxist theory is pretty crude, but the idea seems very interesting, and its hard to ignore the strong socialist sentiment on/.
You may or may not be correct here, its very hard to tell. What you have discovered is, IMHO, one of chemistries dirty little secrets.
The article talks about BC2N and BC4N, boron carbonitride. You refer to the apparently common CBN, carbon boronitride. The trick is they may be the same thing! As far as I know there is no strong convention for naming covalent complexes like this. Generally one tries to alphabetize (e.g the researchers use of this convention), however, engineers have this nasty habit of ignoring international convention in the "pure" scientific disciplins (metric?) and so somebody probably named the cutting material you describe CBN and it stuck. In short, CBN == BC2N
As support I suggest that the lowercase c, (cBN) is very important. In chemistry, (I don't know about materials) lowercase prefixes often denote geometric/ spatial/ optical isomers, in this case cubic. Also, the fact that it is harder-than-diamond is key, this is unique as far as I know. Finally I would mention that the intial description of cBN (cubis boronitride?) makes no mention of carbon whatsoever, yet at the close of the article it is described as cBC2N. I believe this is a case of a journalist who does not understand the material s/he is covering.
Halogens are the period of compounds including Flourine, Chlorine, and Bromine. Their presence in drinking water can be unhealthy, can be real nasty combined with hydrocarbons (think dioxins).
Halon is a chemical fire extinguisher (mostly chloro and fluro-carbons) which are inert and displace oxygen. Radon is similar in that it is nonreactive chemically, however it is RADIOactive. Comes up from the ground as a gas and "pools" in basements (being heavier than air). It poses both a radiation hazard and suffocation (exludes oxygen). Phew, there is your chemistry lesson for today.
"Actually, I kind of see it as a blessing that these really good stories get stuck in the back."
I agree strongly on this point, however, this article lacks anything of broad interest as far as I can tell. I had hoped that this was some sort of imminent disaster, in a timescale we could be conecerned about. My initial expectation was a government attept at releasing the pressure using high explosives, that would be of interest to all of us.
Photons do not impart energy in the form of mass x energy, they have no mass. They impart momentum, as h / lambda, to the craft. Twice as much if they are reflected (rather than absorbed).
I believe upgrading the clocks would improve the accuracy. The sats all "know" their relative positions, and update constantly, to a maximum resolution based on the clocks, and it would make sense that they include a ground location(s) defined as stationary. I think the most significant limit to the system is the clocks.
What are brain waves? Most of these studies are done with MRI or CT scans, as far as I know. I'm curious what sophisticated techniques they're using for collecting their data.
Not only will this allow sequencing on minute amounts of DNA but it appears to be nondestructive to the degree that one could get multiple reads, i.e reverse polarity and reread the sequence(s). Gaining the holy Felgett's advantage at the cost of a few minutes and a few microvolts. I can't help but also think of the potential this holds for data storage. An array of micopores on a chip could read massive amounts of data off a drop of liquid in minutes.
They don't give hearts to those who are less likely to survive. But more importantly, in this case the patient is summer from severe kidney failre as well as long term heart failure. A heart transplant wouldn't be very viable at the currentr time, but if they can prolong his life long enough for the fluid to clear the lungs (done already) and the kidney failure to stabilize he may become more able to recieve a transplant.

Why I remmber when water pollution was first recognized as a problem, how to solve it? "Dilution is the Solution"
Granted this took place a decade before I was born but the point is valid; we continually try and hide/ bury/ burn/ put somewhere else our collective waste. It is unbelieveable that we still fail to realize the folly of this mindset.
Although Unix is more reliable, Redman said, NT may become more reliable with time.
Oh, and we may be able to steer the ship with time. Aren't mission critical applications supposed to be reliable above all else? No matter how much better NT preforms over a lower level system a "Smart Ship" dead in the water is vulnerable to a 50-year old U-boat (how funny would that be) not to mention a small fishing boat laden with explosives.
The separation of classified and unclassified hardware is legendary among those who have ever worked under high security clearance. An excellent example is ethenet cables: once used to transfer classified data, they must be secured and destroyed. I question how much one could glean from an ethernet cable, even if it had not been wiped. But then again they lost entire hardrives full of classified data at LANL.

Cause nobody can spy on you inside LANL. Not even with a satelite.

hmmm, so if I get you right,
Two kinds of laws:
1. Big guy with a stick says "This is how it is, see?"
2. Wide eyed kid points and says "This is how it is, see?
". . . I don't like this, where's my stick?"

Actually it exploded during pre-flight tests in April.
