Special investigations and charges. FiveThirtyEight has compiled a dataset of all U.S. special counsel, independent counsel, and special prosecutor investigations since 1973 — and the people charged in them. Related: FiveThirtyEight’s visual comparison of the Mueller probe to other investigations. Bonus: FiveThirtyEight’s Amelia Thomson-DeVeaux has also been tracking major lawsuits related to President Trump and his administration; that dataset currently contains 45 civil cases and 6 criminal cases.
Spring firsts. Phenology (literally: “the science of appearance”) is the location-and-species-specific study of recurring plant and animal phenomena, such as the annual arrivals and departures of migratory birds. The USA National Phenology Network collects observational data from thousands of citizen scientists, professional researchers, NGOs, and other groups; assesses the data’s quality; and makes it available to explore and download.

Uber for X. From Alexis C. Madrigal, writing at The Atlantic: “Now, a decade since Uber blazed the trail, and half that since the craze faded, we built a spreadsheet of 105 Uber-for-X companies founded in the United States, representing $7.4 billion in venture-capital investment. We culled from lists, dug in Crunchbase, and pulled from old news coverage. It’s not a comprehensive list, but it is a large sample of the hopes and dreams of the entrepreneurs of the time.”
