Comment: Destroying satellites for fun and profit (Score 1) 550

If you just blow up satellites with rockets, it will put debris into its orbit, drastically reducing the usability of the orbit for anyone.

If you build a weapon to simply disable the satellite, or better yet, cause it to drop out of orbit and burn up without hitting anything, then you would have an advantage. I hope that we are keeping tabs on anyone that plans to develop that kind of technology.

I cant imagine that China didn't learn their lesson from blowing up satellites.

So we need MORE clouds? The Earth is already about 70% covered in clouds.

I think the Earth already does a pretty good job of putting water vapour into the atmosphere on a daily basis.

The cloud cover is in dynamic equilibrium. I don't think that spraying some water air changes that equilibrium. Because, like I said, it's already dynamic equilibrium!.

We need to find the Earth's thermostat and turn it down a bit. I think it has to do more with the composition of the atmosphere.

Scientists Erase Specific Memories In Mice 320

Ostracus writes "It sounds like science fiction, but scientists say it might one day be possible to erase undesirable memories from the brain, selectively and safely. After exposing mice to emotionally powerful stimuli, such as a mild shock to their paws, the scientists then observed how well or poorly the animals subsequently recalled the particular trauma as their brain's expression of CaMKII was manipulated up and down. When the brain was made to overproduce CaMKII at the exact moment the mouse was prodded to retrieve the traumatic memory, the memory wasn't just blocked, it appeared to be fully erased."

New State of Matter Could Extend Moore's Law 329

rennerik writes "Scientists at McGill University in Montreal say they've discovered a new state of matter that could help extend Moore's Law and allow for the fabrication of more tightly packed transistors, or a new kind of transistor altogether. The researchers call the new state of matter 'a quasi-three-dimensional electron crystal.' It was discovered using a device cooled to a temperature about 100 times colder than intergalactic space, following the application of the most powerful continuous magnetic field on Earth."
