The Globe reports that a former MIT chemist caused an all-out evacuation of her Temple Street brownstone by conducting some freelance science experiments. The woman, who has not been identified by name, had mixed a cocktail of chemicals on the floor of her apartment, directly behind the State House.

"Any time you have someone who knows what they're doing with chemicals, it can be a bad situation," Deputy Fire Chief Robert Calobrisi said.

No word on whether either lead or gold was found on the premises.
