Kamala Harris took command of the debate stage on Thursday night time after time -- from quieting a chaotic stage by admonishing her rivals not to engage in a food fight to demolishing Joe Biden with an impassioned critique of his comments about working with segregationists and his record opposing aspects of busing.In what was unquestionably the most difficult moment of the night for the former vice president and front-runner, Harris challenged him for invoking his work with segregationists at a recent fundraiser. She then went on to disassemble his record on busing.It was a spell-binding moment that showed not only her skills as a tough and unsparing debater, but also the fierce side of her persona, which her supporters believe will be devastating up against President Donald Trump."Vice President Biden, I do not believe you are a racist and I agree with you when you commit yourself to the importance of finding common ground, but I also believe and it's personal and it was hurtful to hear you talk about the reputations of two United States senators who built their reputations and career on the segregation of race in this country," Harris said.She said Biden had worked to prevent the Department of Education from integrating school busing during the 1970s, and that decision hurt a little girl in California."That little girl was me," Harris said with emotion swelling in her voice. "So I will tell you that on this subject, it cannot be an intellectual debate among Democrats. We have to take it seriously.

"I do not praise racists. That is not true. Number one. Number two, if we want to have this litigated on who supports civil rights, I'm happy to do that."After 1928

JACKSON, Miss. — Days and days of heavy rain have forced authorities managing dams in Mississippi and Tennessee to release more water, worsening the flooding for people living downstream. Dramatic video posted by a Tennessee fire department showed the impact: Two houses tumbled down a bluff over the Tennessee River, while many others have been swamped to their rooftops. Entire neighborhoods have disappeared in muddy water below the Tennessee Valley Authority's Pickwick Reservoir. In Mississippi, people in and around the capital of Jackson are bracing for more flooding as the rain-swollen Pearl River is expected to crest on Monday. 651

  

It may seem like an ordinary scene: Children and adults playing on pink seesaws, carelessly laughing and chatting with each other.But this is a playground unlike any other. These custom-built seesaws have been placed on both sides of a slatted steel border fence that separates the United States and Mexico.The idea for a "Teeter-Totter Wall" came from Ronald Rael, an architecture professor at the University of California, Berkeley, and Virginia San Fratello, an associate professor of design at San Jose State University -- and it was a long time coming.In 2009, the two designed a concept for a binational seesaw at the border for a book, "Borderwall as Architecture," which uses "humor and inventiveness to address the futility of building barriers," 768

  

It's a familiar refrain. Parents lament that technology is turning good, legible handwriting into a lost art form for their kids.In response, lawmakers in state after state -- particularly in the South -- are carving out space in teachers' classroom time to keep the graceful loops of cursive writing alive for the next generation. 343
