'Who will we dress for, now?' Fashion photographer Bill Cunningham dies

Cunningham was a street life photographer; a cultural anthropologist; a fixture at fashion events; and a celebrity in spite of his desire to keep the camera focused on others, not himself. "My whole thing is to be invisible. You get more natural pictures that way, too," Cunningham wrote in 2002. He summed up his approach this way: "I let the street speak to me." Many readers of the Times loyally flipped open the Styles section every Sunday to see what Cunningham was seeing all around the city. His death, several days after suffering a stroke, was announced by The Times, where he worked for almost four decades. The newspaper's publisher Arthur Sulzberger said in a statement, "We have lost a legend, and I am personally heartbroken to have lost a friend."

And he sees the combined companies as changing the world. "The potential is there for Tesla to be a $1 trillion market cap company, if we play a major role in transitioning the world to a new form of energy generation, and storage and transport," he told investors Wednesday morning. But shares of Tesla tumbled more than 10% in trading Wednesday following the announcement. And SolarCity, up 17% Tuesday night, closed up only 3% Wednesday amid doubts that shareholders will OK the deal.

How Brexit impacts the U.S. economy

The so-called Brexit has wide implications for the U.S. economy, which is already facing a slew of headwinds. The chief of the U.S. central bank and top monetary policy setting official, Janet Yellen, forewarned earlier this week that Brexit "would negatively affect financial conditions and the U.S. economy." Trade between the two nations only makes up 0.5% of U.S. economic activity. However, the connections go well beyond direct trade between the two global powers. The effect on America can come through a number of chain reactions -- a Brexit domino effect on the global economy. Here are four ways the wake of Brexit could hurt the U.S. economy.
