Re:Extremely sceptical
Your skepticism is well warranted.
No, it's not. According to this report from four years ago, stem cells have already been used to restore movement to paralyzed mice.
The thing that bugs me is, why hasn't this been tried in humans sooner? -

Re:Kyoto
The Kyoto treaty had nothing to do with reducing CO2 emissions. It doesn't meaningfully affect India or China, each soon to dwarf the US in emissions, and no one is making any real changes to meet their goals - just paying the fines. The Kyoto treaty was a thinly disguised attempt to tax America and transfer our wealth to other countries. Sacrifice for no real benefit. Gee, sounds like socialism.
Just because you think one performance/pollution tradeoff is optimal, that doesn't mean that others must necessarily agree. You might not see driving a smaller car as a reduction in your standard of living, but you don't get to choose the values that others live by. If it weren't important to them, they wouldn't pay such a substantial premium to drive big vehicles.
Fusion has been 20 years away for 50 years now - I'm not holding my breath. These new pebble-bed fission reactors look quite practical, however, and would solve the various problems associated with fossil fuels neatly - *if* that power can be used to heat houses and run cars. If dense hydrogen storage is possible it would be a huge help in solving the infrastructure problem, and funding has been directed to that research effort. It already seems to be producing results, assuming these guys aren't full of shit. Good old American, err, Danish ingenuity!
Honestly, are you really interested in reducing CO2 emissions? Or are you only really focused on trying to remove the status symbols of people who beat you at life? -

Re:Your link is the bible
Did you ever notice how science changes its anwsers so damn often. But the Bible stays the same.
Actually, real scientists have used this event to prove a hypothesis. In 1999, Chandra X-Ray center suggested that the shape of the rings resulted from a cavity, caused by the explosion, in the dust and gas surrounding the star. They predicted that the supernova explosion would produce a shock wave which would hit the edges of the cavity and produce a dramatic increase in X-Rays. This is happening as predicted. http://www.sciencedaily.com/releases/2005/08/05082 1234547.htm
You see, that's the difference between science and superstition. Science makes predictions which can be tested. That's why it sometimes changes. Superstition is not testable. That's why it stays the same. -

There is actually a lot of evidence backing my point...
This is hardly "insider" stuff--it is "popular science" material my friend. Hormones affect sleep, sleep affects hormones and so on...it is all linked and involves more than cognitive abilities are physical alertness. Sleep deprivation (especially long-term/chronic) can affect growth, metabolism, aging, sex drive...everything. There is no way a single drug that merely keeps you physically and mentally alert without sleep would be healthy if used chronically. -
Re:Power concernsGood point. The #3: "Last a long time" is usually equivalent to "stores a lot of energy". And mostly it contradicts with #1 and #2. Whenever you have anything that produces and stores large ammounts of energy you are bound to have toxicity, explosive potential and other harmful effects.
For example it has been long known that you can have very long lasting nuclear batteries using betavoltaics (couple of a source of beta radiation and a p-n junction and you have your battery), but would you put it on your lap that is the question.
Either it has so much shielding that it is too heavy, or it is nice and light and will make you grow another set of legs (or something else down there...).
But I remember that there was an article about someone developing such a battery here the link, I think.

Re:Sometimes it's good to forget.
It's pretty easy to block the transfer of memories from short term to long term. That's one of the reasons why people who have been in serious trauma often forget what happened right before.
Removing long-term memories is more of a challenge. There have been some studies that suggest that recalled memories can be blocked, though it's not as permanent as people thought.
Movies like the Eternal Sunshine of the Spotless Mind may be fun to watch, but that sort of surgical removal of memories doesn't seem to be possible. What seems to typically happen is that the connections to recall certain memories are weakened over time due to disuse. My understanding is that those synaptic connections are eventually "reused" in the formation of new memories, though the specifics are very complicated. -

Impatience
Sometimes technology development is harder than we think it ought to be, sometimes it's easier. The harder stuff is just naturally going to be slower; the easy stuff (like electronics has been the past couple of decades) makes us impatient in other areas. Science fiction's generally rosy portraits of future advances are probably also part of the problem.
On the other hand, maybe Huebner is right - we're about to enter an inevitable period of slowdown and even loss, similar to the dark ages after the Greeks and Romans. The parallels between the US and the Roman empire are pretty interesting...
Luckily we do have some competition in space that might revive things again... -
Re:Time frame

No. The reporter mentioned grass, the researcher did not. This article does not mention grass or other Earth life, so I think we can assume that the reporter got carried away. I expect that introducing Earth life is not part of the plan (or at least not expected to work). -

"Evolution", for something with the long, long reproductive cycle of humans, takes tens of thousands of years to produce significant differences. To get an evolutionary difference in intelligence or learning ability, then, we'd need all of the following to hold:
a) Environmental pressures that select strongly for intelligence/learning on one population.
b) Environmental pressures that select weakly or negatively for intelligence/learning on the other population.
c) Effective continuance of that selective disparity for tens of thousands of years.If you were truely applying "the principles of evolution", you'd be able to isolate and explain all of those factors. As it is, though, it's not at all clear what type of environment would select for intelligence/learning significantly better than another environment, and it's not clear that such environments could have been maintained over the last 50,000 years. It's also not clear that the answer wouldn't be "sub-Saharan Africans---similar to having vastly higher genetic diversity than the rest of the world---also have both the lowest and the highest adaptations for intelligence/learning, making societal notions of ethnicity useless in this regard.
In other words, if you truly were applying "the principles of evolution", you would come to the conclusion that this is a question we don't have enough information to answer, and one that almost certainly doesn't fall neatly along "racial" lines.If you're just using "evolution" as a magic incantation to try to justify your predjudices, though, then, yeah, people will call you racist. And they'd be right.

Re:The Russian court has got see reason, here.Astrology seems to concern itself with two completely unrelated areas: personality and predicting the future. The latter is obviously suspect, since there's no evidence that the position of the planets foreshadows events. But it does it seem so far-fetched that human personality varies in a cyclical fashion? A recently published study linked the season of birth with the onset of menopause. Relevant quotes:
"Nevertheless, the data seem to suggest notable effects of the month/season of birth on the length of a woman's fertile life...The next phase of the research was seeing whether the season of birth of the women in the study influenced their psychological profile -- affecting their susceptibility to conditions such as anxiety and depression, for example. 'Results so far seem promising.'"
The effect is far from being conclusively proven, but if you discard the traditional astrological mechanism that the planets cause certain personalities instead of simply being correlated with them, its a plausible, logical hypothesis.

My own healthIf you want to avoid most of the cancers just get a daily dose of any antioxidants in your diet. One of the most effective combos I have found is coffee/red wine/hot cocoa for drinking and corn/potatoes
/brown rice/beans as staples in my cooking. A lot of the exotic fruits that are extremely high in antioxidants do not actually absorb into the body in any great amount. One of the greatest antioxidants is the chlorogenic acid in coffee as over 75% of the antioxidants are absorbed into the body whereas most vegatables besides corn require special cooking and mixture with fats to allow absorption at all.In regards to the sun I work with my shirt off and let the window open for about an hour a day. I have a 'jekyl/hyde' tan where half of my body is becoming bronze as the other is pasty. I should look into knocking out this wall here and putting in a window.

Per the Phd working on it:(last sentence in article)
"We are not yet at break-even," Taleyarkhan said. "That would be the ultimate. I don't know if it will ever happen, but we are hopeful that it will and don't see any clear reason why not. In the future we will attempt to scale up this system and see how far we can go."
Slashdot is full of nay sayers , and detractors .
I am optimistic they will make headway with this because it already
cost thousands of times less to build, and the materials involved
are common, simple, and inexpensive .
Bubble fusion just makes sense monetarily .
Price and availability do have an affect on science .
Ask the dying bucket of bolts called ISS .
ITER is a grand idea, but to scale to power plant abilities
it would cost far more then the billions already slated for
a so called small reactor .
Size alone of these reactors would border on the super collider
that was started in texas then abandoned and now used to urban
warfare combat training . *sigh*
A bubble fusion reactor on the other had could end up powering
cars, homes, boats , planes, spacecraft, etc etc .
Once they get past break even, something ITER hasn't done yet ,
then we could see something amazing .
Budget limitations will make bubble fusion more appealing to
more scientists due to its low cost to experiment in restrospect
to plasma based toriod magnetic monsters costing billions .
Keep in mind Acetone is urine, and we could end up taking a leak
to power our world, pretty ironic if u ask me .

Re:As opposed to...

yep, single-molecule transistors made previously
I work on sort-of-related stuff in condensed matter physics, and I have skimmed through some papers about the subject, and I had the same thought as the parent (though I was too lazy to post) - that it's cool, but not quite "revolutionary" and that other groups have come up with single-molecule transistors before.
Here's a link describing what two groups published in Nature back in 2002 about single molecule transistors (maybe what the parent post was referring to):
http://www.sciencedaily.com/releases/2002/06/02061 3073522.htm/
I briefly scanned through the Nature "News and Views" that introduces and supplies background for this recent paper (from today's Nature) and it looks like the main innovation is that the group used a different technique from earlier molecule transistors. According to that Nature article, previous groups relied on metalmoleculemetal types of molecular junctions. Apparently, these junctions have extra geometric complexity due to the metal-molecule coordination that can complicate the charge transport measurements. This group avoided the "geometric uncertainty" by using a junction on a semiconductor (silicon) instead of a metal. They apparently added a carbon atom with an unpaired electron as a 'dangling bond' on the surface of the silicon electrode to form the molecule-electrode interface. The interface is then a covalent bond, instead of the more complicated coordination bond from other molecular junctions. Anyway, that's why I gathered from a quick reading of the Nature summary article, but I don't know about the subject in much depth.
There's definitely a lot of potential with this stuff, though. -
