Evolution of mathematics traced using unusually comprehensive genealogy database.
Most of the world’s mathematicians fall into just 24 scientific 'families', one of which dates back to the fifteenth century. The insight comes from an analysis of the Mathematics Genealogy Project (MGP), which aims to connect all mathematicians, living and dead, into family trees on the basis of teacher–pupil lineages, in particular who an individual's doctoral adviser was.
An interesting look back at history.
The same DNA analysis used to find the alleged Golden State Killer has led to the arrest of a second alleged murderer. It’ll likely lead to more.
I can see this going to the Supreme Court sooner than later on privacy related underpinning. I can’t help but recall the words of Jed Bartlett in The West Wing when he was saying in season one that privacy would be one of the most pressing issues for the Supreme Court in the coming century.
A stunning story with some ingenious detective work. I worry what the potential privacy problems are off in the future, though one of the ideas here is that it actually helps protect the privacy of some individuals who are wrongly and maliciously accused and thus saves a lot of time and money.
The subtleties will be when we’re using this type of DNA evidence more frequently for lower level crimes while at the same time the technology gets increasingly cheaper to carry out.
