Does Boston boast more brainiacs than anywhere else in the country?

By one measure it does.

The Howard Hughes Medical Institute, a nonprofit research organization, on Wednesday named 19 new medical investigators who will receive a total of $200 million to do whatever biomedical research they want. For the second time since 2013, roughly a third of the investigators were based in the Boston area, a greater concentration than any region in the country.

The institute, which was started in 1953 by the business magnate, aviator, and maverick film tycoon whose name it bears, will provide each investigator with $8 million over seven years. The term can be renewed after a scientific review. Recipients were picked from 675 eligible applicants.
