Andy Updegrove writes: Humanity today is almost completely dependent on huge pharmaceutical companies to create the drugs we need. But these companies focus exclusively on drugs that can be sold at high prices to large populations — in other words, to patients in developed nations. This means that those who live in the emerging world that suffer from the remaining "neglected diseases," like Malaria and drug resistant TB, have no one to depend on for relief except huge charities, like the Gates Foundation. They also have no way to afford many of the patented drugs that do exist. But there is another way, modeled on open source software development, which relies on crowd sourced knowledge, highly distributed, volunteer efforts, and advanced open source tools. That methodology is called Open Source Pharma, and it has the potential to dramatically drive down drug development while saving millions of lives every year.
