EXPERIMENTAL DRUG YIELDS DRAMATIC WEIGHT LOSS

Retatrutide, an experimental shot by drugmaker Eli Lilly, was so powerful in human trials that participants stopped taking it because they thought they were losing too much weight.

HOW SPACEX'S IPO CEMENTS ELON MUSK'S GRIP ON THE COMPANY

SpaceX has adopted a corporate governance policy that will erode typical shareholder protections and give Elon Musk virtually unchecked executive authority when the company goes public.
