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.
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.
Paul Holes was on the verge of retirement, having never completed his decades-long mission to catch the Golden State Killer. Then he had an idea: Upload DNA evidence to a genealogy website.
On today’s episode:
• Paul Holes, an investigator in California who helped to crack the case.
• A spate of murders and rapes across California in the 1970s and 1980s went unsolved for decades. Then, last week, law enforcement officials arrested Joseph James DeAngelo, 72, a former police officer.
• Investigators submitted DNA collected at a crime scene to the genealogy website GEDmatch, through which they were able to track down distant relatives of the suspect. The method has raised concerns about privacy and ethics.
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.
The clue that led investigators this week to the door of the suspected Golden State Killer came from an unexpected source: GEDmatch.com — an amateur genealogy website that’s something like the Wikipedia of DNA.
