Google announced a big change in its approach to search today.

The search giant said the move was the first step in transitioning from an "information agent" to a "knowledge agent."

"The Knowledge Graph enables you to search for things, people or places that Google knows about — landmarks, celebrities, cities, sports teams, buildings, geographical features, movies, celestial objects, works of art and more — and instantly get information that's relevant to your query," Amit Singhal, a senior vice president at Google, wrote.

Alexander Arbuckle, the defendant in the first Occupy Wall Street case to go to trial, has been found not guilty after video of the incident he was involved in showed him breaking no laws. The Village Voice reports:

"The protesters, including Arbuckle, were in the street blocking traffic, Officer Elisheba Vera testified. The police, on the sidewalk, had to move in to make arrests to allow blocked traffic to move. But there was a problem with the police account: it bore no resemblance to photographs and videos taken that night."

President Obama and congressional leaders lunched at the White House Wednesday on sandwiches the leader of the free world purchased during a visit to a Washington, D.C., eatery where he met earlier in the morning with a group of small-business people.

Descriptions of the White House lunch meeting from those on the opposing red and blue teams aware of the details of the discussion made it sound like yet another meeting featuring the nation's top policymakers that you could have accurately described beforehand.

The House and the Senate are once again at odds: This time over a reauthorization of the Violence Against Women Act.

The Senate passed a beefed-up version of the bill and the House removed those new protections in their version. With that, the conversation has shifted into the controversial areas of immigration and identity politics. The House debated the bill — H.R. 4970 — today and a vote could be scheduled for this week.

Facebook's initial public offering is shaping up to be one of the largest in history. This morning the company told the Securities and Exchange Commission that it was expanding its offering ... again.

Now Facebook is planning to raise up to $16 billion from investors by taking a small slice of the company to the public. And it will likely be worth more than $100 billion on its opening day of trading. It could easily go higher.

Preventing the exposure of kids to lead is a great idea, the Centers for Disease Control and Prevention said today.

The public health honchos agreed with an expert panel that recommended in January that anything greater than 5 micrograms per deciliter of blood for kids 5 and younger should be considered dangerous. That's half the current standard and represents the first reduction since 1991.

There was a deadly clash in northern Syria on Tuesday, but it was different than many other such episodes over the past 14 months of the Syrian uprising.

This time, United Nations monitors were watching. The monitors are in Syria to keep an eye on the government forces and the opposition, who are supposed to be observing a cease-fire and opening a dialogue.

But the trouble Tuesday began with a funeral the northern Syrian town of Khan Sheikhoun.

A man who was killed by Syrian security forces over the weekend was about to be buried. The funeral was held in a part of town that claims to be free — meaning it no longer considers itself under the control of the Syrian government.

Chuck Brown, known as the "Godfather of Go-Go," a style of percussion-heavy funk pioneered in Washington, D.C., died Wednesday. His death was reported by The Washington Post, quoting his manager, and other local outlets confirmed his death with family members.

Brown had been hospitalized for pneumonia. He was 75.

As the Post notes, Brown's signature was a gravelly voice that "capitalized on funk's percussive pulse to create go-go."
