Comment Re:Despicable Greenpeace (Score 2) 465

Why is that? Please edify me as to how I am a sucker because I think Greenpeace is more responsible in their actions than BP? I notice that you had to make an ad hominem comment, rather than actually saying what was inaccurate about my comment? Also, whoever moderated my comment down, why not join the discussion and tell us what I said that was so offensive to you?

Comment If you read the article in Science (Score 3, Insightful) 135

you'll see they have pretty solid evidence that this particular type of comet (Jupiter family) had a deuterium/hydrogen ratio in water that is very different from earth, whereas many asteroids (chondrites) have about the same D/H ratio. All they were saying was that this type of comet was not responsible for delivering most of earth's water, which seems reasonable based on their evidence (see figure 3 from the article).

Comment why is it always comets and asteroids? (Score 4, Interesting) 46

Why is it that astrophysicists always think that biogenesis and evolution have to come at the point of a comet or asteroid? Isn't it also possible that earth created the conditions for life at hydrothermal vents and other potent chemical-energy sources? The conditions at a hydrothermal vent seem much more conducive to biogenesis than an asteroid impact, and the opportunities for prolonged chemical synthesis of many organic compounds would far exceed anything you would get from occasional comet or asteroid strikes.

This is true and well known to the police, and scientists as well. Alcohol inhibits glutamate (excitatory neural) receptors in the brain, so the more you drink the more your brain's activities are depressed. So the more drunk you get, the more impaired your mental functions become, and the less motor control you have. Pot has virtually no effect on glutamate receptors in the brain. It acts on endocanabinoid receptors which are in a whole different class. They are involved in other functions, including hunger sensations, pain sensations, and memory. There is some speculation that this system may be involved in clearing old memories, perhaps to make room for new ones. So ironically, pot would probably be better than alcohol for people in bars drinking and trying to forget bad memories.But pot does not impair driving abilities, and tends to make drivers more cautious. Testing for pot in drivers should not result in a fine, or license suspension, it should result in a "have a nice day" response from the officer as he hands you your license back.

Comment repeated concussions are far more damaging (Score 4, Insightful) 233

"Sports" like boxing and football will never be safe because they involve repeated blows to the head. Single blows are bad enough if they are of high force, but research has shown that repeated blows to the head, even moderate ones, are more than additive. The window of vulnerability has been found to be between 3 and 5 days, meaning that you need to avoid any additional impacts for that long after you have an initial impact. Because boxing and football involve hitting the head repeatedly over the course of a single day, it is apparent why football players and boxers have the worst cases of post traumatic encephalopathy (PTE). The only way to prevent this is to stop after the first blow to the head, which would make both of these "sports" unplayable by human beings. If you want to help out with this problem, invent robots that can engage in these activities. They too will sustain damage over time, but unlike human brains, they will be repairable. They also won't file lawsuits.

So far that hasn't happened on my system, even with settings pretty much maxed out. But I do get big lag whenever I am being pursued and I turn a corner and leave the ghost image behind indicating the last place I was seen. It is at least a half second delay. Try setting everything to max, and then turn one thing down at a time and see if there is one specific setting that is causing the issue.

come on, admit it, you haven't even played the game. You probably haven't even seen it on anyone else's computer. Take a look at the PC version and tell me you've seen that much stuff on the screen at once with that much view distance and all the lighting effects. I said the game was buggy, but I have had more issues with Borderlands the presequal so far.
