The mercury depends on efficiency aswell. Modern CFLs have
To put that into perspective, 5 pounds of your average Swordfish would have more mercury than a modern CFL -- and you don't eat the bits of a broken CFL.
In "Graft vs. Host" there is a specific side-effect known as Graft-vs-Tumor. The effect has been known for some time, with the main problem being the lack of control over whether the transplanted immune cells attack both the tumor and/or the host, as GvH can result in serious or fatal reactions.
In this case, I see the info page for the study mentions that Granulocytes are known to attack tumors without causing GvH, which appears to be the novel part of this study. Let's hope they've got a really efficient method for depleting T-cells from the mix.
It would be kind of like the stealth 'fighter' from a number of years back. I believe it flew for about seven or eight years before the Air Force admitted that it existed. And the Air Force name for the project was definitely not what the aerospace media called it. (Nor was it shaped anything like the Revelle model that was created representing a stealth fighter.)
One thing about the stealth fighter that sticks out in my mind from back then -- at the time toy makers and magazines like PopSci was coming out with fantasy paintings of futuristic-looking "stealth" fighters, Discover Magazine did an article in which they did some scientific and engineering guesswork of what a stealth plane would look like.
On the cover of that issue was a painting of their extrapolation: A black triangular flying wing, with intakes on the top surface of the wing, and a zig-zag rear margin. I couldn't believe it when years later I saw a picture of the actual stealth bomber.
I bet if he had instead changed some everyone's grades to "D-E-A-D-B-E-E-F" the judge would have just lold and put a "1337 Pwnage" into his permanent record instead.
We often see the scientific community putting manned spaceflight down, saying that it is not useful for scientific research. Had we sent people, with even a minimal laboratory, we'd have known within about 15 minutes whether what they were digging up was ice or not. Since the lander doesn't have an "ice" experiment/module on board, we're reduced to guess work. As other folks have mentioned, the lander does indeed have a module for ice. However, I'd still say "this is why robots are great for science" even if it did not -- because you can revise your designs, build a second robot for that purpose, and send it, and still spend far less than what it would cost to send a human.
It is quite true that reducing the cost of launch capacity would reduce the cost of sending the human. However, I do not see any reason why this would not also proportionally reduce the cost of launching larger (or faster, or more numerous) robots. The one real benefit is public relations, the ability to mint space-cadet heros.
You are a sucker. I've purchased two copies of Vista. One retail and one with a new laptop. In the license agreement that came with both of them, there is a clause that allows you to use Windows XP instead of Vista. No need to pay extra. Unfortunately, I tried getting a downgrade with my Vista Ultimate retail, and was told by their tech support that it only applies to OEM installs of Ultimate and Business. "Downgrade rights are not granted under FPP system licenses." (FPP = Full Packaged Product)
Something like this has been recognized to occur in certain cancers, through Oncosomes. In such cases, the cancerous cells bud off vesicles which fuse with healthy cells, containing oncoproteins that induce a cancer-like phenotype in the target cell, despite no change in the healthy cell's genotype.
Anyway, I find this interesting. While restricted to situations where you could physically make the delivery, it raises the possibility of obtaining (temporarily) effects similar to those of gene-therapy without the gene. By producing your target protein ex vivo you eliminate an entire class of problems revolving around how to introduce and express foreign DNA.
Interesting indeed... I vaguely recall some debate when sequencing the platypus was proposed, over whether or not it was a worthy use of funding and sequencer time, being that it was not considered a representative of any medically or commercially important organism, or one of the various "model" laboratory organisms.
Anyway, saw a comment posted as a reply to a Nature article on it which also suggested we take a look at "other 'outlier' organisms, including the echidna, birds like the kiwi or tinamous, tuataras, nautilus, and similar organisms." Sounds like a good idea -- here's hoping we see sequence data from other living fossil organisms.
There actually is an antiviral which I expect would be active against this virus -- Pleconaril. Unfortunately, it has not been approved, and I haven't heard of much work being done with it after Phase II trials finished.
That being said, this particular virus really isn't a danger to healthy adults, mostly to children and the immuno-suppressed.
-You could spin the foil to keep it stretched. Might need some extra weight attached to the edges. This would make it difficult to steer.
-The holes will probably cause some distortions in the surface from uneven distribution of stress. Maybe it would be better to replace holes with clear patches of film, just selectively deposit the silver film in some areas only. You would lose some portions of the spectrum based on what your film was not transparent to.
-The focus problem is maybe the largest. I wonder if there's some way to get around the limitation of need to be exactly at a single plane for focus -- some kind of holographic capture within a 3-D block of "film", with later recovery of an image through post-processing.
Methanol itself is not toxic; rather, the toxicity is due to the accumulation of its metabolites -- formaldehyde and formic acid.
Wow. By the same token, antifreeze (ethylene glycol) isn't really toxic. It's just the metabolites that will do you in.
Can we just permanently ban Wikipedia references here and stop the madness? Wow, both snarky and unjustified. Attitude aside, the wikipedia article is technically correct from a biochemistry view, and practically correct from a medical view as well -- the distinction is what allows Methanol and Ethylene Glycol poisoning to be counteracted (if caught sufficently soon after ingestion).
Block the metabolic conversion with the appropriate enzyme inhibitor (or a competitive substrate like lots of regular ethanol) and you block the toxicity. The Methanol and Ethylene Glycol will gradually be excreted, and do relatively little harm in the meanwhile due to their low inherent toxicities.
Oh yeah, and... increased food prices are actually a good thing for all but the richest people in the world. The poorest people in the world make their money from selling food. Farming poor make their money from selling food. Urban poor have to buy it. The mix that you get will depend very much on a particular country -- their population size, how much arable land, and such.
Consider the game of Chess. It is a deterministic game, with a huge but finite space of games that exist. Any game could then be considered to take a one of the fixed and limited number of paths through through this space. As such, it could be said that a chess game is not "played", it is only "discovered".
However, the experience of actually playing or watching chess results in an entirely different feeling -- so maybe it is not such a useful way to define it.
History constitutes less than 2000 years. Thats the farthest back for which there are any usable records. Chinese records go back a bit further than that. While the oldest writings formally intended to serve as historiography are 2.1k years old, there are about 3k years of actually readable materials recorded by contemporaries of that time.
In addition, there are several thousand years worth of recorded events before that, but by historians living long after (although still ancient by our perspective) they supposedly occured. Many such cases can be considered the "historical" myths of their time, although in other cases historians mention the titles of prior works now unknown to us (thus indicating that these were written, rather than oral, legends).
I knew someone would say this. Alright, I'll bite. Name one plausible environmental damage scenario (other than full-out nuclear war) that would cause a significant proportion of human extinction. Hmm... Oceanic Anoxic Event. These events have been associated with warm climates and very high CO2 levels (~1000ppm). However, I should note that this type of extreme scenario has not been predicted to result result from human activity. Rather, some huge natural calamity would probably have to occur to trigger one.
From Nature News:
Interest was rekindled two years ago when researchers at the Tokyo Institute of Technology synthesized a new superconductor based on iron rather than copper. The material also featured oxygen, lanthanum and phosphorus, but its transition temperature was just 4 degrees above absolute zero, no better than the very first superconductor discovered a century before.
Then this February, the same group announced an exciting development. The researchers had replaced phosphorus with another pnicogen, arsenic, in the layered material and - boom - the transition temperature shot up to 26 K (Y. Kamihara et al. J. Am. Chem. Soc. 130, 3296â"3297; 2008). Subsequent tweaking has already boosted that temperature above 50 K. âoeWe all were surprised,â says materials scientist Hideo Hosono, who led the study. It would seem that this research is coming out of Japan, not China.
I used to know an engineer who worked for AMD, and one of the things he would tell me about were the problems with the merger with ATI. There were a lot of manufacturing and engineering differences between the two companies that made it difficult to combine designs from the two. In addition, the poor financial situation of AMD meant they didn't have enough time and money to complete the "Fusion" CPU/GPU combo -- one of the main drivers behind the merger in the first place.
He said that the company will still bring something out, and that something will still go by the codename "Fusion", but it will not be the product originally envisioned at the time the companies decided to merge. He speculated maybe some kind of Multi-Chip Module -- essentially just a separate CPU and a separate GPU die mounted into the same packaging.
Alright, predictions folks. How long until the Math team / Debate team / Model UN have to pee in a cup to prove they aren't taking "Brain Enhancing" Drugs? When the office betting pool places big bucks on the Math teams. When the big Debate match goes into overtime and pre-empts your regularly scheduled programming. When the Model UN gets recruited for million-dollar sneaker endorsements.
Hmm... wonder if the 1000HW my aunt uses is vulnerable? As a pretty-much obsolete unit, it's old enough that it might fall off the list simply because of its age.
You are correct that "correlation is not causation". This particular statement seems to be trotted out in any research-related posting and appears to be highly correlated with an increase in +5 moderations within science topics. However, we also have a postulated mechanism, which has already been previously explored and found plausible, and some experimental evidence from animal models.
For instance Prarie Voles and Vasopressin, in which by manipulating the Vasopressin V1a gene, males of a normally promiscuous species of Vole were rendered monagamous (and more attentive to their single mates). Only partially relevant, but suggestive.
Most importantly, it points at the possibility of producing directly relevant evidence in future experimental model (in which the species selected would be one that exhibits both "altruistic" and "ruthless" behaviors). I don't imagine such an experiment would be quick or cheap, as more socially sophisticated species tend to be more difficult to work with.
In any case, it sounds like your comment is directed at the particular news article (which mentions very little of the background), and not at the research in particular -- am I incorrect in drawing this distinction?
Rick Astley's character sheet neglects to mention a few things -- he is under a permanent Geas of loyalty. Rick is unable to abandon party members for any reason (although his party members may choose to leave him if they initiate the separation). In addition, he is unable to speak any untruth which causes emotional anguish to another.
Rick also has a compulsion to explain to others his emotional state and how he is feeling, which results in a penalty to all rolls involving deception (except vs. ducks). However, this feature is not a Geas and is merely a personality trait.

Inquiring minds want to know -- has "I.P. Freely" made it onto the High Scores list yet?
And, will there be a port for the Nintendo Wii? I bet it would make a big splash in the market.
