Foxconn May Close Factories In China
If China isn't the best place in the world to hire cheap, slave-like labor, where does that leave?
Eventually, Foxconn and all the companies that rely on it to produce cheap electronics are going to have to start paying workers more. That cost will get passed on to us, the consumers.
This is a good thing as far as I'm concerned. I'd rather pay more for my laptop or iPhone than have to live with idea that my high-tech gadget habit is causing suicides on the other side of the world.
Should Kids Be Bribed to Do Well in School?
So, let's say this works and kids get better test scores when we pay them. Are they actually learning anything?
(And, do we care whether or not they learn anything if test scores get kids into college, get them jobs, etc.?)
Twitter Predicts Box Office Results
I'm sure some Gecko-type has already thought of this, and is trying it in a secret lab somewhere. Then again, if I was an investment banker, I'd be immensely greedy and paranoid and never tweet about any company I was interested in.
Tsunami Warning From Space?
how is detecting a tsunami from space better than our current method?
1. seismometers detect earthquake, computers & scientists quickly determine possibility of tsunami generation and issue a warning.
2. buoys in the ocean and pressure sensors on the ocean floor detect passing tsunami energy wave, allowing warnings to be updated.
This system works well in about 90% of cases where it's installed; it still isn't fully operational in the Indian Ocean(the Pacific system worked very well after the Chile quake in February), but should be soon.
The only major gap that leaves is the places where time from wave generation to impact is only a few minutes -- that is, a city like Padang, Indonesia, or Seattle, which sit just a few miles from a huge fault. What do we do then? A satellite might be useful, but only if it can detect the formation and size of a tsunami and issue a warning *instantly*.
Fortunately, those cities have a natural warning system in place: the earthquake itself. They're so close to the fault that inhabitants will certainly feel any tsunami-generating quake.
So, spending tens (hundreds?) of millions of dollars on a satellite or satellites to monitor tsunamis probably isn't the best course when you can educated people about how to get out of harm's way for a tiny fraction of the cost.
PARC Builds iPod-Sized HIV Detector
So, according to the article, the device uses a laser to optically measure white cell count, not look at HIV itself.
Aren't there other diseases of the immune system that could trigger a false positive, and lead to someone who is HIV-negative being prescribed anti-retroviral drugs?
I suppose in places like Haiti, Lesotho, South Africa and elsewhere, HIV is such a problem that the benefit would outweigh the risk. Still, I wouldn't want to be the one who was misdiagnosed...
