Students across the country are spelling their way to greatness in the Scripps National Spelling Bee program. Students are in the process of advancing from classroom to school to region to earn a spot in the national finals in National Harbor, Maryland, in May 2020. Spellers who win their school spelling bee but don’t advance past their region can keep their dream alive of competing in the national spotlight. For the third year in a row, the Bee is offering its RSVBee program. It is a participation pathway that qualifies more spellers for the national finals. It is the only way students living in unsponsored regions can advance and is an additional opportunity for the best spellers in the country to compete on the national stage.The Bee created RSVBee with an eye toward fairness, accessibility, maintaining the integrity of the competition and delivering a quality Bee Week experience for all. The Scripps National Spelling Bee has more than 250 sponsors across the country who support the program and make it possible for local students to advance. Still, there are unsponsored sections in the U.S., and some of its sponsored regions have grown so large and competitive that RSVBee is the Bee’s answer to address access and fairness. “We’ve known for many years that large numbers of excellent spellers have had limited access to the national finals or no pathway at all,” said Paige Kimble, executive director of the Scripps National Spelling Bee. “We created RSVBee to address this very issue and make our iconic competition accessible to a wider population of children who love words and language and enjoy competitive spelling.” The Bee is narrowing the field of the national finals to about 400 competitors, down from last year’s 562, with the intent of providing spellers and their families with a more personalized, quality experience during Bee Week. Parents can apply on behalf of their child for one of about 140 total RSVBee invitations at 1975

Some good news for nap fanatics -- a new study has found that a daytime nap taken once or twice a week could lower the risk of heart attacks or strokes.Researchers from the University Hospital of Lausanne, Switzerland studied the association between napping frequency and duration and the risk of fatal and non-fatal cardiovascular disease complications.Tracking 3,462 people between the ages of 35 and 75 for just over five years, the report authors found that those who indulged in occasional napping -- once or twice a week, for between five minutes to an hour -- were 48% less likely to suffer a heart attack, stroke or heart failure than those who did not nap at all.The observational study, which was published in 732

President Trump seems nowhere near making a deal with Democrats over border wall funding. And instead of waiting on a compromise, Trump's claiming he can declare an "immigration emergency" to get his way. But experts aren't so sure about that. "I don't think he can go through with it," said James Thurber, professor of government at American University and author of "Rivals for Power: Presidential-Congress Relations." "Maybe it will take a judicial action to force him not to do it, but I think that he probably found out that there was such a thing as the national emergency powers of the president and that stuck with him, and so he tweeted and stated things that were well before legal advice given to him."But is there precedent for Trump's potential move? They have been used by President George W. Bush during times of war and by President Barack Obama after Russia annexed Crimea. "Emergency powers were used to build facilities in Afghanistan and Iraq, but they've also been used since the 1976 National Emergencies Act that defines what you can and cannot do. They've been used probably 30 times, primarily on trade issues but also related to war and war powers," Thurber said.An 1204

SAN FRANCISCO — A man suspected of robbing a pharmacy in the San Francisco Bay area was fatally shot by officers who thought a hammer he was carrying in his waistband was a firearm, police said Wednesday.Details of the shooting were revealed even as some California counties and cities began plans to end curfews after days of largely peaceful protests over the death of George Floyd while in police custody in Minneapolis.Sean Monterrosa, 22, of San Francisco is the first confirmed death at the hands of law enforcement related to smash-and-grabs and protests in California since Floyd’s death. Vallejo Police Chief Shawny Williams said officers were responding to calls of looting at a Walgreens early Tuesday when the shooting occurred.Officers said Monterrosa began running toward a car when he suddenly stopped, got on his knees and placed his hands above his waist, revealing what appeared to be the butt of a firearm in his waistband. “This individual appeared to be running toward the black sedan when suddenly he stopped, taking a kneeling position, and placing his hands above his waist, revealing what appeared to be the butt of a handgun,” Williams said.An officer shot five times through a police car window, striking him once.The object Monterrosa had turned out to be a 15-inch hammer that was tucked into the poclet of his sweatshirt, according to the chief.“The intent was to stop the looting and arrest any perpetrators if necessary. The officers reacted to a perceived threat,” Williams said.John Burris, an attorney for the family, said he is appalled police would shoot at a person who was on his knees with his hands raised.The officer who shot Monterrosa is an 18-year veteran of the force and has been placed on leave pending an investigation. 1781

Summer is in full swing, and with the warmer months comes the mosquitoes. Not only are the small insects pesky, they are considered the deadliest animal in the world, believe it or not. More than 700 million people around the globe get sick from mosquito bites, and more than 700,000 people die from those bites each year."We always see West Nile Virus peaks right after the Fourth of July weekend, because people have been outside and not protecting themselves," says Kylee Grenis, an expert on mosquitoes. Grenis helped us conduct an experiment to find out which bug repellent works the best.We purchased three mosquito traps. We sprayed one trap with DEET. The other with a top rated non-DEET spray called Skin So Soft by Avon. The third trap was a controlled trap with no spray.The traps were hung next to dry ice in a mosquito-infested park."We are going to hang some dry ice near those traps to simulate a human standing and breathing and hopefully that will help attract more mosquitoes to our traps," explains Grenis on the use of dry ice. After an hour, the trap sprayed with DEET had one mosquito. In the Avon-sprayed trap, there were no mosquitos. In the control trap, there were six mosquitos. The sprays kept the mosquitos away.As far as sprays go, Grenis says she still prefers DEET. "It is great at making you invisible to mosquitoes,” she says. “That blocks the receptors so that they can't detect your carbon dioxide signature." But, many consumers fear products with DEET are not safe. "I think a lot of the time people get it confused with DDT,” she explains of Dichlorodiphenyltrichloroethane (DDT), a chemical compound banned in many countries due to the danger it poses to wildlife and the environment.DEET is safe to use and just like the Avon spray, and both sprays are effective in keeping mosquitos away during the summer time months. 1872
