Transcranial magnetic stimulation (TMS) is a diagnostic tool that delivers a high-intensity magnetic pulse over the skull and neck, stimulating the upper motor neurons and nerve tract. This allows the timing of electrical impulses traveling from the brain to muscles to be measured as well as interconnections within the brain to be studied. The technique has also been used to treat neurological conditions, such as migraine, epilepsy, and alcoholism. What are some of the risks associated with TMS?

The original Sunshine Skyway Bridge over Tampa Bay was completed in 1954. A new southbound span was opened in 1971, but only nine years later, it was destroyed when the freighter Summit Venture collided with a support column during a storm, sending more than 1,200 ft (366 m) of the bridge plummeting into the bay. The collision caused several automobiles and a bus to fall 150 ft (46 m), killing 35 people. What tragedy had occurred within a mile of the bridge just months earlier?
