A task that once took days has been reduced to hours, thanks to the use of drones and laser technology.The Scripps Institution of Oceanography is mapping the shoreline of San Diego's coast  to study beach and cliff erosion. The new technology, paid for by the California State Parks and the Army Corps of Enginners, has made that task much easier."This is allowing us to get a more comprehensive view of the beach and the cliffs," says lead researcher Adam Young.Young and his team will drive the entire coast from La Jolla to Oceanside twice a year. They're using a laser enhanced camera and a drone to create a 3D map of the coast. Over time, they'll be able to compare the maps and see where and how the beach is eroding."We're going to have to start looking to the future," Young says. "And we're not going to be able to prepare properly unless we collect data and understand what's happening now."In addition to the twice yearly studies, Young says they'll look at sand levels after storms and at how sand moves throughout the year.Young says it can help predict what areas of the cliffs are susceptible to collapse. 1139

A sharply divided U.S. Supreme Court has denied a rural Nevada church’s request to strike down as unconstitutional a 50-person cap on worship services as part of the state’s ongoing response to the coronavirus. In a 5-4 decision Friday, the high court refused to grant the request from the Christian church east of Reno to be subjected to the same COVID-19 restrictions in Nevada that allow casinos, restaurants and others to operate at 50% of capacity. The church argued the hard cap on religious gatherings was an unconstitutional violation of its First Amendment rights. Chief Justice John Roberts sided with the majority in denying the request without explanation. 676

A new campaign is bringing attention to an issue that hasn't been front and center since the pandemic started – missing children.“There has been a lot of awareness, a lot of things have changed, but regarding her case, unfortunately there's nothing,” said Jessica Nu?ez about her missing 15-year-old daughter, Alicia Navarro.Navarro, who has autism, was 14 when she vanished in the middle of the night last September from her home in Glendale, Arizona.Alicia played online games and her mother thinks she was lured away by someone she met online. They had even discussed the dangers in therapy.“And then she wrote me a letter where she sweared to me she was coming back, so that’s what has me very worried, because I know her intention was for her to come back and that’s why I won’t stop looking,” said Nu?ez. “I won’t stop looking until I get answers because it’s been so long.”In a new effort to bring attention to missing children like Alicia Navarro, their pictures will be featured on some gas station pump video screens. Alicia's picture will be up in Arizona.The National Center for Missing & Exploited Children is coordinating the effort featuring various different missing children's pictures in the states they disappeared from.Her mother wants people to know she looks young for her age and has a noticeable scar on her right knuckles.“People tend to forget so my goal is to continue sharing her story and having her image out there,” said Nu?ez.There's also a Facebook page, called "Finding Alicia," where you can share her picture. 1557
