Kamala Harris has endorsed Joe Biden for president, pledging to “do everything in my power” to help elect him. She is the latest dropout from the Democratic presidential race to line up behind the former vice president in his battle with Bernie Sanders for the nomination. The decision by the California senator who was one of three black candidates seeking to challenge President Donald Trump further solidifies the Democratic establishment's move to close circles around Biden after his Super Tuesday success. In a statement, Harris says Biden would be able to “steer our nation through these turbulent times, and restore truth, honor, and decency to the Oval Office." Although Harris is now rallying around the former vice president, she challenged Biden early in the campaign. During the first Democratic Party presidential debate in June, Harris slammed Biden for his role in decreasing school busing during the 70s. “There was a little girl in California who was part of the second class to integrate her public schools, and she was bused to school every day, and that little girl was me,” Harris said. “I will tell you that on this subject, it cannot be an intellectual debate among Democrats. We have to take it seriously. We have to act swiftly.” 1267

In like a lion, out like a lion?Don't let this weather April Fool you, after a warm weekend in many parts of the US, temperatures are dipping dramatically.From St. Louis to New York, millions of Americans enjoyed barbecues, beaches and parks with temperatures reaching into the 60s and 70s. Even parts of Alaska reached 70 degrees on Saturday -- the earliest in the year anywhere in the state has hit that high.But here's hoping the tulips and the sprinkler systems haven't yet made their way back into your yard as temperatures will be falling rapidly across large swaths of the country.By Monday morning temperatures are expected to drop so dramatically that over 20 million people from Arkansas to North Carolina will be under a freeze warning.Northeast likely to experience most dramatic changeCNN meteorologist Michael Guy expects a stunning reversal of temperatures for April 1 -- ranging from 10-20 degrees below average for this time of year.Guy says the most extreme drops are forecast to be in the Northeast, with New York City dropping from Sunday's 65 degree high to a forecast 46 degrees, Boston falling from 70 to 45 degrees and Washington DC from 64 to 45 degrees.The cold snap is due to a strong cold front moving in and the battle between warm versus cold air this time of year, he says.Most people in the Northeast, mid-South and Midwest will see highs in the 40s and the 50s.That means a city like Pittsburgh, after reveling in a high of 67 Saturday, will fall back to earth with temperatures in the upper 30s on Sunday.As the United States wakes up Monday, many of us will be trading out our flip flops for a closed toe and pulling our winter jackets back out of the storage closet.This is only temporary, however, as some part of the South are expected to bounce back to spring by Wednesday with Atlanta seeing temperatures of nearly 80 by next weekend. 1886

In the battle between the adolescent penchant for hitting the snooze button and parental desire to rush them onto an early morning school bus, experts say science is increasingly siding with the snooze.The biological clock of teens is shifted, Dr. Mary Carskadon, director of the Sleep and Chronobiology Research Lab at EP Bradley Hospital, told CNN. That means everything influenced by the circadian timing process, including sleeping, waking and eating patterns are set later.And if teens have trouble naturally falling asleep at an early hour and don't get the recommended eight and a half to nine hours of sleep, asking them to be awake, ready and in a classroom by 7:30 a.m. can wreak havoc on their systems, Carskadon said.Students in one state have gotten a reprieve from the early morning blues. California Gov. Gavin Newsom signed legislation Sunday that pushes back start times for middle and high schools to align with teens' circadian rhythms. It's a move sleep experts hope more school districts will follow.That's especially because research suggests that when teens get a later start in the morning, they can do a better job of checking off the things on many parents' priority lists like:Paying attention and getting their homework doneFour out of five public middle and high schools in the US start before 8:30 a.m., the earliest time recommended for teens, according to the US Centers for Disease Control.Carskadon says the negative consequences of early waking on academic performance are obvious: Students have more trouble concentrating in class and retaining information, feel tired during the day, have more absences and tardiness and have a hard time doing their homework and class reading well.There isn't enough time between when their clocks tell them to go to sleep and when they need to be in class to get the sleep they need, she says. And to make matters worse, for many teens, their bodies are telling them it's still time to be in bed when they are trying to listen in class."A lot of kids will just be asleep in first period because their brains are -- almost literally -- on the pillow and not yet in the classroom," she said.Avoiding the junk foodWhen students are off of their regular sleep cycle, they often also fall off of their ideal eating cycle too, Carskadon said. Since the biological clock influences humans' eating, straying from the circadian rhythm could mean eating too much or eating the wrong food at the wrong times, she said.Who among us reaches for a healthy snack when we are tired and awake when we aren't supposed to be, asked Stacy Simera, a licensed social worker who is chair of the sleep committee for the Ohio Adolescent Health Partnership.That disruption not only means worse nutrition, but it can lead to an increased risk for Type 2 diabetes, Carskadon said.Staying out of troubleWhen it comes to impulse control, Carskadon and her colleagues say teenagers already have the accelerator pushed down without any breaks. That's because the emotional side of the brain is well developed in those years, but doesn't have a very strong link to the executive decision-making side.And neuroimaging studies showed that link is even weaker in teens without enough sleep. The result can be trouble controlling their impulses and increasingly engaging in risky behaviors like foregoing helmets, driving under the influence and abusing substances, Carskadon said.Keeping happy and safeFrom a physical health perspective, teens who get adequate sleep also are shown to suffer fewer car accidents and sports injuries, said Simera.She says teens fall asleep easiest and get the best quality sleep from 11 p.m. to 8 a.m. -- the sweet spot. And research shows that straying from that sweet spot and sleeping less is correlated to depression, anxiety and suicide, she said.One study found that for each extra hour of sleep adolescents get, 3899
