A 45-year-old Harvard man jumped off the Massachusetts Avenue Bridge shortly before noon. According to the Suffolk County District Attorney's office:

Troopers were able to bring the man from the water into a State Police vessel and transport him to a nearby dock, from where he was taken to Boston Medical Center. Based on the facts and circumstances available thus far, the incident does not appear to be the result of criminal conduct and the man is expected to survive.

Workers at the Museum of Science spotted a seal swimming in the Charles, so naturally, they tweeted for some help to the New England Aquarium, which will now look for the critter. To which the Museum of Science replied:

Awesome! And if you happen to notice any dinosaur fossils, we're happy to help.

Boston Magazine reports the seal may still be in the river this morning.
