In an abrupt about-face, Hillary Clinton says she will endorse her 2016 rival Bernie Sanders if he wins the Democratic nomination to face President Donald Trump in November. The former secretary of state had earlier refused to say whether she would endorse Sanders in an interview with The Hollywood Reporter published Tuesday, instead telling the outlet: “I'm not going to go there yet.” Clinton tweeted Tuesday night: “The number one priority for our country and world is retiring Trump, and, as I always have, I will do whatever I can to support our nominee.” The two had a bitter rivalry for the 2016 nomination. 628

It used to be that learning happened in the classroom, but these last few months it’s happened a lot in front of a screen. Many parents have debated about how much screen time is too much and what’s best as school comes to a close and we hit the summer break. Now, some experts say that thinking screen time is bad might be old-school thinking. Video games have changed a lot since the days of Atari Pong. Now, more than ever, they’re designed to keep the consumer engaged. One of their biggest targets: adolescents. "Video games have classically been more of a problem because once you really engage that reward system, it’s frustrating and tough to pull kids off," said psychiatrist Joel Stoddard.He said that’s because a child’s reward system is stronger than a child’s control system. And there’s a difference in the way the brain reacts to video games than it does to the online schooling. "For most of the video games that kids are really into, like Fortnite and Zelda: Breath of the Wild, those games are designed to really engage their reward systems and keep their attention. So, that’s a little bit different than online school, which is not really designed in the same way to grab hold of those areas in the brain that are involved in like ‘this is what I want’," said Stoddard. "When kids are engaged with a teacher or with academic content online, that serves a very different purpose than playing a video game or having a zoom call to socialize with a peer," said Jennifer Walsh-Rurak, Vice President of the Northeast Region of Fusion Academy. That interaction, whether it’s playing video games with friends online, or FaceTiming, is better than no interaction. "In this day and age where they can’t naturally go outside and engage with kids in the neighborhood, we don’t want to discourage them from having that social peer interaction which we know is so critically important," said Walsh-Rurak. Stoddard says the extra time on the screens, isn’t all bad. It can actually be beneficial to an extent."The brain gets better at doing what it does so, when we’re interacting with screens all of our visual and screen areas are getting better. If you’re gaming, maybe some of those special attention and those reward areas get more sensitive, if we’re doing social media we’re going to be highly attuned to what does that ‘like mean, what does it not mean’. The brain just gets better at what it does," said Stoddard. However, it’s important to think about what else the kid could be doing instead of playing on the screen. "We do know that video games can suck kiddos in so they’re not actually having normative typical social interactions. They might gain weight, for example, and have disrupted sleep. And those have that sort of knock-on effects," said Stoddard. "I think proactively before it gets to that point, ensuring that kids have time built into their day where they plan to be outside maybe walking the dog, engaging with a family member in a conversation, reading a book. Doing something that very intentionally takes them away from that screen," said Walsh-Rurak. 3102

Joe Biden has formally clinched the Democratic presidential nomination, setting him up for a bruising challenge to President Donald Trump that will play out against the unprecedented backdrop of a pandemic, economic collapse and civil unrest. The former vice president has effectively been his party’s leader since his last challenger in the Democratic primary, Bernie Sanders, ended his campaign in April. But Biden pulled together the 1,991 delegates needed to become the nominee after seven states and the District of Columbia held presidential primaries Tuesday. Biden reached the threshold three days after the primaries because several states, overwhelmed by huge increases in mail ballots, took days to tabulate results.Heading into Super Tuesday, Biden was the underdog. He lost contests in Iowa, New Hampshire and Nevada and was struggling to fundraise. Then, Biden scored a huge win in South Carolina on February 29, thanks in large part to endorsements and support from prominent black Democrats in the state. Following the South Carolina race, opponents Pete Buttigieg and Amy Klobuchar dropped out of the race and endorsed Biden. Biden was able to parlay his success in South Carolina into a massive Super Tuesday which catapulted the former vice president from underdog to favorite overnight. As the spread of COVID-19 forced Biden and opponent Bernie Sanders off the campaign trail, Sanders opted to drop out after the Wisconsin primary, leaving Biden standing alone.Biden will formally be nominated in August at the Democratic National Convention. The convention is slated to be held in Milwaukee, but it’s unknown if the coronavirus could interfere with having an in-person event. Biden issued the following statement late Friday:A little more than three months ago I stood on stage in South Carolina and told the American people that ours was a campaign for everyone who has been knocked down, counted out, and left behind. Those words take on an ever greater resonance today, at a time when so many Americans are hurting and have suffered so much loss. So many feel knocked down by the public health and economic crisis we are weathering. So many feel counted out and left behind by a society that has for too long viewed them as less than equal, their lives as less than precious.This is a difficult time in America’s history. And Donald Trump’s angry, divisive politics is no answer. The country is crying out for leadership. Leadership that can unite us. Leadership that can bring us together. We need an economy that works for everyone — now. We need jobs that bring dignity — now. We need equal justice — and equal opportunities — for every American now. We need a president who cares about helping us heal — now. It was an honor to compete alongside one of the most talented groups of candidates the Democratic party has ever fielded — and I am proud to say that we are going into this general election a united party. I am going to spend every day between now and November 3rd fighting to earn the votes of Americans all across this great country so that, together, we can win the battle for the soul of this nation, and make sure that as we rebuild our economy, everyone comes along. Today, I’m once again asking every American who feels knocked down, counted out, and left behind, to join our campaign. Because we aren't just building the movement that will defeat Donald Trump, we are building the movement that will transform our nation. I truly believe that when we stand together, finally, as One America, we will rise stronger than before. This is the United States of America. There is nothing we can’t do, if we do it together. 3674
