The MacArthur Foundation announced its "genius grant" recipients last week, four of whom live in Massachusetts. On Oct. 3 we spoke with Watertown bow maker Benoit Rolland about his award. On Oct. 9, we were joined by a local neurosurgeon, Dr. Benjamin Warf, whose pioneering efforts to treat intracranial diseases in very young children have earned him the $500,000 grant.
