Does this urban legend hold any truth? Bruce Bassett, head of the Cosmology research group, worked with his team at last month’s Data Quest to uncover the "true" story.

Exposing the Mafia's hidden assets in Africa

The African Network of Centers for Investigative Reporting (ANCIR) and the Investigative Reporting Project Italy (IRPI) created an online archive of the documents that helped them track the Mafia's secret ownership of everything from diamond mines to nightclubs, game farms and luxury country estates in Africa. These 108 documents are hosted on ANCIR's ‪#‎sourceAFRICA ‬platform, a resource that allows users to comment on the documents and help ANCIR and IRPI find new leads. View the ‪#‎MafiaAfrica‬ investigation here.

What else the fellows have been up to

• ANCIR's #sourceAFRICA, created by ICFJ Knight Fellow Justin Arenstein and Code for Africa, developed a beta WordPress plugin and oEmbed so you can embed their resources on your own site. Download it here.

• What should journalists learn from the Rolling Stone's November story on campus rape? Heinrich Böhmke, a legal advisor to ANCIR, shared some insights with the Global Investigative Journalism Network.

• The Indigo Trust features Code for South Africa’s Mapping Cape Town’s Budget project.
