SAN DIEGO (KGTV) -- It’s almost time to welcome back the nail-biting excitement of the Scripps National Spelling Bee.This year’s countywide bee will be held on March 15 at the McMillin Companies Event Center at Liberty Station.Roughly 100 spellers are expected to take the stage, making competition fierce.Last year was an exciting year for the competition as it saw its youngest speller ever, Edith Fuller of Oklahoma, who was only 5-years-old when she qualified.Fuller went all the way to the national stage. The spelling bee has been around for more than nine decades.The bee was founded in 1925 and has been held every year since, except during the World War II years of 1943, 1944 and 1945.In 2017, the competition celebrated its 90th National Spelling Bee.2017’s winning word was marocain, which is “a ribbed crepe fabric used in women's clothing.”The Scripps National Spelling Bee will begin May 29 and end on May 31.  943

SAN DIEGO (KGTV) - It's been months since construction began on eight prototypes for a wall to span the U.S.-Mexico divide. The structures, built by six companies that have largely remained out of the spotlight, faced a barrage of tests by border officials, reportedly including jackhammers, saws, torches and other tools and climbing devices to try and thwart the walls.The contractors tasked with building the prototypes were: 456

SAN DIEGO (KGTV) - Inside a mobile machinist shop, the Marine Corps can now print polymer and metal parts on the go.Operated by the 1st Marine Logistics Group, the Expeditionary Manufacturing Shelter is currently at Camp Pendleton. It houses several 3D printers which each serve a specific purpose."Digital manufacturing can be extremely useful in a combat situation or a disaster zone because we can take this shelter and deploy it to anywhere it's needed. We're able to provide parts that are not readily available, and we're able to get our equipment operational faster," said Staff Sgt. Samuel Margarini.Rather than ordering a part and waiting up to a week, the Marines can re-create a part within 24 hours, improving readiness and operational momentum.3D printing new parts is also cheaper and saves resources. "Since implementation we've had a huge impact on different platforms, we've made parts for trucks, humvees, tanks, and some drones," said Margarini.While only being used in training, for now, shelters like this will eventually be deployed where needed by the Marine Corps. 1098

SAN DIEGO (KGTV) -- It should be no surprise at this point that home prices are still on the rise in San Diego this April. A new report from Zillow shows that, year-to-year, home values in San Diego have risen more than eight percent. According to Zillow, the median home value in San Diego currently sits at just over 5,000. That change marks an increase of 8.4 percent since last April.Meanwhile, rent is also on the rise at a median of just over ,500, or an increase of 3.6 percent since last April.Click on the charts below for more information:  The high cost of housing in San Diego is in stark contrast with national home values.The median home value nationally is 5,600. If there's one thing San Diego and the rest of the nation have in common in this report it's that both saw home values increase by more than eight percent.“Home values are rising faster than we’ve seen in a very long time: The spring home shopping season has been a perfect storm of strong demand and tight supply,” said Zillow senior economist Aaron Terrazas.Nationally, the number of new homes being built is also seeing a decrease. “Sluggish new construction has exacerbated the supply situation and homes that are hitting the market, are moving very quickly once they do. Americans are also in a spending mood, boosted by recent tax cuts and rising wages. Millennials who long delayed becoming homeowners, are out in force – a shift we’re also seeing in softer rent appreciation," said Terrazas. Zillow adds that nationally, home values are rising at their fastest pace in 12 years. RELATED: SD woman climbs out of 3,000 debt hole | This is how much space 0K will buy you in SD | How much you need to earn to buy a home in SD 1790

SAN DIEGO (KGTV) - Inside the 3D Innovations Lab at Rady Children's Hospital, the hearts, bones, skulls, and spines of patients are brought to life in a new way.Justin Ryan, Ph.D. is director of the lab. Using 3D printers, they can replicate a patient's anatomy down to every precise detail, giving doctors critical information before surgery.“The concept is by giving our doctors more information they can perform a better procedure; they can even perform it with less time. So that means less time under bypass, less time under anesthesia, which is great for the patients themselves," said Ryan.For example, if a patient is a candidate for a stent or valve, doctors could use the 3D model to try different sizes before entering the operating room. “We give them more information to plan a better procedure," said Ryan. While some of the models take several hours, many can be created within the day. “There isn’t an average day, I might have a cardiac case in the morning, an ortho case in the evening, I'll have a doctor have an idea for a medical device that they wanted to design or develop, and that all happens here," said Ryan. Ryan says the 3D models are also useful when explaining the procedure to families. The technology is currently being funded by grants and donations, at no extra cost to families. Ryan believes insurance eventually will help cover costs. 1381
