Shifting Gears: An embarrassing flub at Lyft, a leaked Tesla email, and Marc Anthony's yacht catches fire

Delta flight attendants say their uniforms are making them lose their hair, break out in hives, and cough uncontrollably

For 18 months, Delta flight attendants say they've battled skin lesions, fatigue, migraines, and hair loss. They think it's because of the chemicals in their new uniforms.

In some cases, medical-leave requests and requests to wear different uniforms were rejected, with some attendants saying their jobs were threatened.

Death, taxes and leaked emails from Tesla

If there's one thing you can count on from the Tesla beat, it's leaked emails from within the company.

Candice Poon, Cara Dick, Mike Finger got a stern message from Lyft

Some Lyft users received a message from the company Thursday saying their names violated the ride-hailing service's community guidelines.

In the notification, Lyft didn't provide a reason for flagging an account beyond saying the name "doesn't align with its Community Guidelines."

Lyft said in a statement to Business Insider that the prompt was sent in error.

RIP Marc Anthony's yacht

The Latin mega-star's $7 million, 120-foot yacht capsized after a fire in Miami on Wednesday, but nobody was hurt.
