Chips can be super tiny, spinning platters aren't so much. It wasn't that long ago that people were predicting hard drives couldn't get much more dense due to neighboring bits flipping each other too frequently, then they had a breakthrough with perpendicular recording. Look at what a 4 gig microSD card looks like. Then imagine how many of those could fit in a 3.5" drive chassis if carefully stacked them in there. I bet you'd be able to stack more than 1000 easily. Aside from that, even if each format may not be able to scale down significantly further, I can only collect so many TB of "linux isos" before I can't find a damn thing.

There was another paper by Guiguemde and Kip Guy in the same issue that my lab helped with. The problem is that antimalarial drugs need to be affordable for millions of people to take daily in places where people live off less than $1/day. Things like Coartem and even artemisinin combination pills cost too much for most of the countries that need them, due to patents and safe manufacturing facilities or even just raw materials. Luckily, malaria is getting special recognition and that helps a lot with widely dispensing every tool available to combat the parasite.

Wow, so airlines have been hesitant about the idea of wifi and cellphones being on for years and they're running several wifi APs on the space station ? I understand why NASA does this but are planes really that sensitive ?

I've had very good luck with my Sony Clie TJ-37. It did what Palm never did and brough wifi to the mainstream ($ rather than $$$) Palm OS devices. It's worked fine, after that one RMA. 802.11b, speaker, nice screen, a camera, if only it didn't use memory stick media it'd be perfect... well, if they still made them. http://www.bargainpda.com/default.asp?newsID=1933
