Contributing to the cause of biology (beyond research)
Wikipedia has a dedicated portal called Biotechnology, which has some promising content right now. A formal categorization of topics is available, also major keywords have a longer description. The problem is, that many specialized articles are missing right now. They are only available in a dedicated research encyclopedia which is sold as a commercial product for 2000 US$. That means, there is a knowledge gap between the content in Wikipedia and the content in encyclopedias used by researchers. So if somebody has too much time he can try to transfer the knowledge from Academia into the public domain and create some Wikipedia stubs. This would help to bring Open Science forward.
