Is open source the answer for finding cures for tropical diseases?

Only about 1% of newly developed drugs are for tropical diseases, such as African sleeping sickness and dengue fever. While patent incentives have driven commercial pharmaceutical companies to make Western health care the envy of the world, the commercial model only works if companies can sell enough patented products to cover their R&D costs and produce profits for shareholders.

Does cancer run in families?

If you have a relative with cancer, probably one of the most pressing questions is what your chances are of getting it yourself. In a paper published in PloS Medicine, the premier medical journal freely available online, Laufey Amundadottir and colleagues from deCODE genetics (a company that is using genetics to develop new drug treatments) and Iceland’s National-University Hospital go some way toward answering that question.
