At the outset, the Internet was expected to be an open, democratic source of information. But algorithms, like the kind used by Facebook, instead often steer us toward articles that reflect our own ideological preferences and search results usually echo what we already know and like.

Imagine your heart can no longer pump enough blood to your vital organs. Even minimal exercise tires you out, and you're often short of breath when lying flat. Your lungs are accumulating fluid. Your kidneys and liver are impaired.

You've been hospitalized and started on an intravenous drug that improves your heart's ability to contract. It has helped, but it is not a long-term solution. You need a new heart.

A burned body was found Saturday at the scene of a brushfire north of Los Angeles that has scorched 31 square miles and prompted the evacuation of 1,500 homes, authorities said.

The body was discovered outside a home on Iron Canyon Road in Santa Clarita, and detectives are trying to determine whether the person was killed by the blaze or another cause, Los Angeles County sheriff's Lt. Rob Hahnlein said. The home also may have burned, he said.

California Gov. Jerry Brown has denied parole to former Charles Manson follower Leslie Van Houten, 66, who is serving a life sentence for her part in the cult's notorious killing spree in Los Angeles in 1969.

In April, a California parole panel had recommended that Van Houten — the youngest of the cult leader's so-called family — be granted parole after decades of good behavior in prison, as we reported.

Appearing on stage together for the first time since Friday's vice presidential announcement, Hillary Clinton and Tim Kaine made a push for voters of color by highlighting his record on diversity and civil rights.

Kaine also spoke about gun violence, job creation, equal pay and raising equal pay — all mainstays of Clinton's campaign.

Clinton said Kaine has "lived" the values of diversity. That, she argued, is in contrast the GOP ticket and last week's Republican National Convention. "Tim Kaine is everything Donald Trump and Mike Pence are not," she said.
