Micro-meteorites aren't so bad. Solar panels have a funny tenancy to be damaged by light. I believe this is the major source of efficiency declines for solar panels in space.
UV rays darken glass and plastic and generally muck around with anything you expose to it.
I don't know... I think I need to agree with AC here.
You said. "one persons moral code should never prevent someone else getting medical treatment."
My morals say murdering someone as a means to provide another person with medical treatment is wrong. And thirty million of my best friends and I will stop you from doing this. So yes, sometimes everyone will have someone else's morals imposed upon them. But sometimes this is a good thing.
Not really.
Apollo was spending ~6 billion dollars per year at its peak and there were 190 million people in the US at the time.
That works out to $32 per person per year, or about $175 in today's dollars.
Pricey yes. Bankrupt? I think not. Though I do agree that it might be better to send that money to the National Science Foundation.
I think the author believes this will allow for more aggressive radiation therapy as treatment for cancer tumors. That wouldn't be a cure, but it would substantially increase the effectiveness of treatment.
It might not be that useful for cancer therapy. If it prevents cells from dying instead of spreading out the time at which cell deaths occur as AC suggests, then it could make the targeted tumors more resistant to the radiation dose.
Huge doses of radiation has two effects on the body. One, it can jumble DNA causing mutations and increasing your lifelong risk of developing cancer. This drug does nothing to combat this.
Two, it jumbles up enough proteins that many cells undergo apoptosis. That means the cells commit suicide believing that they must be defective in some way for all this damage to be present. Thanks to all the holes where the dead cells were, bodily fluids start leaking through places they shouldn't... Like your intestines. This is what causes deaths within the first week or two following radiation exposure.
The drug treats the latter case by preventing apoptosis.
Now, the fear is that this drug could increase the risk of developing cancer. Often, a cancerous cell is a perfectly normal one except for that fact that it ignores the body's instructions to commit suicide.
The only thing he/she has lost is the opportunity to have submitted an application... Or arguably, the time it would have taken to make up a facebook page with a fake date of birth on it.
sodul has 'lost' very little, so he/she has very little to gain from a lawsuit.
What exactly is the incentive to sue? To expend that much time and money? For what? The burden of a moral case like this one should not fall into the hands of an individual. Or am I missing something about the legal system?
...recent findings indicate that it may actually increase a person's risk of contracting STDs, especially if used frequently. This is because the chemical causes tiny abrasions inside the sensitive vaginal and anal walls. These abrasions may make transmission more likely especially if condoms are not used.
I want to agree with you. But the Manhattan project cost ~$24 billion in today's USD according to wikipedia, and at the end they had 2 working bombs.
When ITER has spent it's 20 billion, we'll hopefully have the knowledge we need to build a working power reactor.
Now. You might say that fusion energy is worth more than an atom bomb or two. But I doubt you would convince someone living in 1944 of that.
Hey. I'm doing my doctorate in the field. (thus the late comment)
As for the computers solving the diffeqs. You may be right and you may be wrong.
The sad thing is, we do not have a set of differential equations that can accurately predict how plasmas will behave across strong magnetic fields. You may have heard that when fluid models are used in turbulent situations, they spit out 'correct' solutions which do not even closely resemble what's actually observed and until recently, the best fluid models predicted that lady bugs should be incapable of flight. (anecdotal stuff I know. I don't have a citation.)
Sadly, things are even more complicated for plasmas. Tokamak plasmas are turbulent. There are multiple species involved. Particles interact by collisions (short range) and by electromagnetic fields (long range). They radiate, they conduct, and currents make magnetic field pertubations that mess with the magnetic field you're using to hold them still in the first place. What's more. The temperature and pressure gradients we are working with are not seen anywhere else that I know of. That is ofcourse how you get a core plasma of 100 million degrees a few meters away from a solid wall that isn't evaporating.
Currently, every plasma model used in fusion is semi-empirical and very limited in application. Even with unlimited computing power, there aren't enough assumptions we can waive to make the ideal model.
However. The problems ITER faces are not so much in plasma physics as they are in engineering. They're struggling to maintain a balance between confinement and stability (the harder you squeeze a balloon, the harder it tries to bulge out between your fingers). They're trying to select their wall materials. One candidate (carbon reinforced composites) can take the heat fluxes, but tends to soak up tritium like a sponge. Tungsten should (hopefully) soak up less tritium, but can poison the plasma if too much of it gets vaporized. What happens to your superconducting magnets when they get bombarded by neutrons? How do you watercool such a large hot surface without risking a steam explosion?
I am saddened by these cost overruns. Sometimes I can't blame people for not wanting to fund it. That doesn't mean the fringe scientists are doing any better of a job.
That is exactly what the standard solution to water acidification is.
They dump lime into whatever body of water they want to cure of acid rain problems.
If it happened this month, most everybody north of the Antarctic Circle would be cruelly cheated. Any time from August through April, though, it should be visible in the night sky from just about anywhere but that same Antarctic. And yes, I'd be willing to drag myself out of bed pre-dawn for this.
I don't think you're grasping the timescales here. Article says:
Over a span of 15 years, the star's diameter seems to have declined from 11.2 to 9.6 AU
Hmmm. If you could purchase a discrete device that would release endorphins whenever you were doing exercise. Would you buy it?
Would you voluntarily rewire yourself?
You have a very interesting analogy.
Though, not the high population.
As viruses in the wildlife and livestock continue to mutate, and humans continue to not be exposed to them because of good luck, good hygiene and a well organized WHO, our lack of resistance to these new strains will build up like deadwood until one day a virus breaks out that we have little resistance to. I'm not about to go trying to contract H1N1 to prevent this. But it is worrysome analogy.
The level 6 pandemic declaration signifies that the WHO believes containment and eradication of the pathogen is not a possible scenario. This means the total number of infected will steadily increase. Exposed individuals will be prescribed bed rest instead of antivirals as supplies become limited to health care workers. A(H1N1) will become a widespread strain of the flu and some day a year, or 2 years or 5 years from now, YOU will contract it and its low (but higher than the seasonal flu) chance of causing fatality.
That doesn't mean it will be terrible. Not much worst than the seasonal flu. Especially since the virus has spread slowly enough that the vaccine should be available before we are at a significant risk of contracting the disease. But in due time, you will be seeing the '1 million dead' headline.
Next time you go to the mall with the family, teach your daughter to talk to strangers. What? No way! Strangers are BAD. BAD EVIL people who want to randomly inject her with drugs so she'll become an addict and a regular client.
Next time you go to the mall with the family, teach your daughter to talk to the right strangers. Mall clerks at security booths. Other parents. Security guards. Bus drivers. If you can teach your daughter to become street smart, she will be able to take care of herself when you're not around. She'll be safe even if you are unable to access your handheld, or the internet is down, or the power goes out...
Ok. The successes of the big three in the US FAR OUTWEIGH those of Google. In their development, they defined America and the world. You can't say that Google is great because it didn't implode over a little recession.
The big three didn't need bailouts during the great depression. Yes they're floundering now. But that's partly due to their past successes which lead to a bloated company, high pensions, large salaries, and many many different models.
What's worst is the device works by surrounding your secret meeting with an array of discreet sensors (aka, microphones). So if two or three extra microphones were to appear in the room, no one would suspect a thing.

The drug treats acute radiation sickness.

It doesn't. Read the article. It lessens the effects of acute radiation sickness.

But there are many more cows per square kilometer in farm land than there are other animals.
Furthermore. Most animals don't have the 4 stomach system using anaerobic bacterial digestion. That's what makes the methane.

So $98 *IS too much for Word
"$98 is too much even for Word itself! "
Why? How much did you pay for it?
Suggested retail price is $229.
Oscilloscope I can understand. But why is it in your car?
Government bailouts???

Absolutely!

I guess it would work for the random passerby...
