Nano cancer drugs move to the next level: humans
A growing number of cancer therapies packaged in infinitesimal particles are making their way to patients.

Can nanotech beat cancer?
Cancer will always be with us in some form, but the fear and devastation it causes could be history within a generation. We'll have the tiniest of things to thank for it.

Medical science strikes out -- but it's okay

Nice article in The Atlantic about researcher John Ioannidis' meta-studies of medical science. Turns out that a third to half of the most respected medical studies have faulty conclusions.

"Physics is to the rest of science what machine tools are to engineering. A corollary is that science places power in our hands which can be used for good or ill. Technology has been abused in this way throughout the ages from gunpowder to atomic bombs."
- John Pendry, Imperial College London
