This weekend marks the official astronomical beginning of summer, and it will also feature a solar eclipse creating a rare “ring of fire”. Set your alarm and watch this unique event online.Around 2:30 a.m. EDT on Sunday, the moon will pass between the Earth and the Sun, causing an annular solar eclipse to be seen from parts of Africa, southern Europe and Asia.Given the orbital position of the Moon and Earth right now, the eclipse at its peak will show a bright ring of light around the moon, which some call a “ring of fire”. The Latin word “annulus” means ring, this is why it is called an annular solar eclipse when there is a ring of sunlight around the moon.The best viewing for this astronomical event will be along a narrow strip from Africa through India to the Pacific Ocean. Here's an animation from NASA of what it will be like. There are ways to watch from the comfort of your own home. Watch the eclipse live here, on the Virtual Telescope Project, or from NASA’s YouTube channel.If you sleep through this one, the next eclipse will be a total solar eclipse later this year on December 14. 1113

Transgender members of the military will be able to re-enlist for service while President Donald Trump's directive barring transgender recruits is under review, the Pentagon has confirmed."Transgender service members whose term of service expires while the interim guidance is in effect, may, at the service member's request, re-enlist under existing procedures," US Army Col. Rob Manning, a Department of Defense spokesman, told reporters Friday. "Current transgender service members will continue serve throughout the military and continue to receive necessary medical treatment as prescribed by their medical provider in accordance with the Military Health System guidance."This is the first time the Pentagon has explicitly acknowledged that transgender service members will be able to re-enlist while it reviews Trump's ban on transgender recruits. 861

TONGANOXIE, Kan. -- A small piece of fabric kept near a classroom door could help protect students in the event of an active shooter. It was three months ago that kindergarten teacher Tiffany Parker was sitting on her living room floor cutting up a fire hose. "One fire hose makes about 100-110 sections, and I had three hoses donated," said Parker, who teaches at Tonganoxie Elementary School in Kansas.Parker used to be the volleyball coach at Tonganoxie High School. She would use old fire hoses to line her practice drills. Now, the fire hose is keeping her classroom safe and secure when it's not just a drill. "We've always done the typical, you know, cover your window, lock your door, move away, but that never seemed to give us enough security," said Parker. On February 14, 2018, 17 students were killed in a school shooting in Parkland, Florida. "You know, seeing my kids' faces when they were first told, 'OK, if somebody comes in, here's what we're going to do,' before I had the Safety Sleeve, and they were still a little fearful," said Parker. Now, in her classroom of 21 students, Parker keeps the 6-inch piece of fire hose hanging by a magnet near the top of her classroom door. In a matter of seconds, the "Safety Sleeve" can be in place."All you do with it is you place it over the door hanger arm, as far as it will go and then they can't get in the door, it won't open," said Parker. The day after the Parkland shooting, Parker brought the Safety Sleeve into her classroom at Tonganoxie Elementary School. After showing her students how it works, Parker said her students felt more secure. "There was such a sense of relief and a sense of security by my kids and a sense of, 'OK, this isn't going to be it,'" said Parker. Parker presented the DIY device to her school principal. Now, she's made hundreds of them for the entire Tonganoxie School District. While she's created a low-cost safety device, Parker said she has no plans to make any money off of the Safety Sleeve. "So many people have asked me, 'Are you going to patent it? You should sell it.' I am not looking to make a dime on kids' lives," said Parker. California, Ohio and South Dakota have already picked up on the idea. Parker said school districts and fire departments have reached out to her to get the Safety Sleeve idea going in their own communities.   2444

There are more than 118,000 teens and children waiting to be adopted in the United States. Now, one group hopes to find parents for these children and using a new PSA to get attention.Isaiah lived in a foster home until he was 16 years old. Then, his social worker introduced him to Amy Arnston and her family."I knew I wanted to be part of their family as soon as I went there that weekend," Isaiah says.The couple had him over for Thanksgiving."They were pretty funny and outgoing people, so I got pretty comfortable with them after a while."A seat at that table turned into forever."I couldn't imagine not having my parents and my family in my life right now,” says Isaiah.However, many children Isaiah's age aren't so lucky.That's why AdoptUSKids is out with new PSAs, showing impactful moments of teenagers’ lives. Memorable moments parents play a big part in.The organization’s hope is more parents will look at adopting older children like Isaiah.They're hoping more parents will look at adopting older kids like Isaiah."[We] took him in as an Arntson. He became my son instantly," says Amy Arnston."There's a kid out there that needed that love that I needed when I was 16," Isaiah says. 1203

There’s a nationwide debate about whether the U.S. should find ways to get the coal industry back up or train workers for new jobs.In eastern Kentucky, families were rocked by a regional recession when the coal industry took a big hit seven years ago.'Their exact words were, 'Due to the decline in the coal market, we're going to have to let you go,' and suddenly I found myself in a place where I had no idea what to do,” said James Johnson, who was let go in 2014.Johnson, who worked as a coal truck supplier in Pikeville, Kentucky, was left at a crossroad. But Johnson found a way to stay in his hometown.He went from coal to coding."Going on four years later, we're still hanging in here," says Johnson, who learned coding with several other former coal workers.Johnson's story isn't unique. It seems like everywhere you go in Pikeville, people are finding ways to survive, outside of the coal.About 21 percent of mining jobs have been eliminated statewide since 2016, forcing people to explore other industries.After nine years working in the mines, resident Harvey Maynard had to look for a new career after being laid off 10 months ago. His skills brought him to baking!"Right now, it's baking donuts!” says Maynard. “Which is a huge change.”Maynard doesn’t just bake—he even decorates, too."Even as a kid I loved to draw, paint, and color,” says Maynard. “I was always very artistic."New jobs are even moving to the small eastern Kentucky city to help. A new distillery opened one month ago; the owners wanted to build there, specifically to help hire coal miners who were out of work.It was a blessing for people like Michael Preston, who after 16 years of working in the coal industry, decided to go back to school. Preston got his associates in electrical technology, and now, he’s the maintenance manager at Dueling Barrels Distillery.     It's a place you look forward to coming every morning,” says Preston. 1950
