One of my favorite posts to WorldChanging has to be Curing Cancer, from July, 2004. In brief, Rice University researchers found that flooding a tumor with gold nanospheres then illuminating the tumor with an infrared laser (through the skin, which remains undamaged) would result in the tumor being completely eliminated. Now Stanford University researchers have accomplished a very similar feat, this time using carbon nanotubes rather than gold nanospheres. The principle is the same: inundate the tumor with the material, illuminate the tumor with a low-power laser, cook the tumor into nonexistence without harming nearby healthy tissue.
Although the Rice University work is further along, this is extremely good news, as it is further demonstration of the viability of the laser treatment model. Given the existing caution about carbon nanotubes in biological contexts, and the demonstrated non-toxicity of gold, it's likely that the Rice approach is more likely to see wider use. But if the gold nanosphere technique proves not to work for some reason (or has other barriers to acceptance, such as cost), it's good to know that the carbon nanotube approach could be able to provide equally-powerful results.
Add other breakthrough cancer-fighting techniques, and we may well see the end of cancer as a scourge by the middle of the next decade, if not sooner.
