Chinese health and Internet authorities have launched an investigation into Baidu, the country's largest search engine, following the death of a college student who accused Baidu of misleading him to a fraudulent cancer treatment.

Experts believe the scandal will damage the credibility of Baidu's search results, and its long-term economic prospects.

On Monday, news of the government investigation caused Baidu's stock to tumble by nearly 8% on the NASDAQ.

Ted Cruz is suspending his presidential bid after a disappointing Indiana loss, clearing the way for Donald Trump to be the likely Republican nominee.

"From the beginning I've said that I would continue on as long as there was a viable path to victory," Cruz told supporters gathered in the Hoosier State. "Tonight I'm sorry to say it appears that path has been foreclosed."

"With a heavy heart but with boundless optimism for the long-term future of our nation, we are suspending our campaign," he said.

The Indiana voters shook up the presidential race Tuesday night, with Ted Cruz ending his campaign after a disappointing loss to now-likely GOP nominee Donald Trump.

Bernie Sanders also bounced back after a string of primary losses with a surprise win over Hillary Clinton. But the Democrat's 6-point win still won't be enough to close the yawning gap between the two.

In Colorado the economy is booming. The unemployment rate is 3 percent. And shiny new skyscrapers are rising all over Denver as revelers pour fistfuls of cash into downtown bars and restaurants.

But no one invited Colorado's public schools to the party.

In 1992, voters in the state amended the constitution with something called the Taxpayer's Bill of Rights, or TABOR.

A study by researchers at Johns Hopkins Medicine says medical errors should rank as the third leading cause of death in the United States — and highlights how shortcomings in tracking vital statistics may hinder research and keep the problem out of the public eye.

It's about 6:30 in the morning at a Starbucks near Santa Monica beach, and David Rodriguez Ordunez is checking Facebook while charging his phone.

He's one of 44,000 people living on the streets in and around Los Angeles — and he's one of three homeless people at the coffee shop this morning.

"Since there's Internet here, that's mainly one of the purposes. I've usually got to find locations to actually have access," Ordunez explains.

Why Starbucks instead of the library? "Well, the library opens like at 10 o'clock or something," he says.

Google is partnering with Fiat Chrysler Automobiles to expand its self-driving car project, the companies said Tuesday in a joint press release.

Though Google has been an industry leader in the quest for self-driving cars, this is the first time it will work directly with an automaker to integrate its self-driving technology into a passenger vehicle.

When I was kid, "What's for dinner?" was not a question you asked at the last minute. My mom, Dorothy Glinton, was an expert at planning what she would put on the table.

"I always knew what I was going to cook. I didn't come in running," Ma recalls.

But these days, even she eats out a few times a week. "But I don't go to a restaurant in the evening," she told me. "I do most of my eating in a grocery story right now, picking up a hot soup, going to a salad bar."

In the past 12 years, the U.S. has spent more than $1.4 billion funding abstinence programs in Africa. They're part of a larger program — called the President's Emergency Plan for AIDS Relief — aimed at stopping the spread of HIV around the world.

Many health officials consider PEPFAR a succes. It is credited with giving lifesaving HIV drugs to more than 5 million people and preventing nearly 1 million babies from getting HIV from their mothers.
