SAN DIEGO (KGTV) - A team of scientists at UC San Diego is getting into the beach business."We looked around and said 'what's the most important thing that we could possibly make?" said Biology Professor Stephen Mayfield. "And that answer is obvious. Flip flops and surfboards."Much more important than the products themselves is what they are made of. Mayfield wants to make plastic products out of more sustainable materials than the traditional petroleum. He says extracting the oil from algae is a much cleaner process. And because it is biodegradable, old and worn-out flip-flops and surfboards won't sit in landfills for thousands of years.The surfboards are virtually indistinguishable from traditional boards, and only cost about five dollars more. Mayfield says about a dozen professional surfers are already using algae boards in worldwide competition.His team at UCSD is working with a local manufacturer to bring the boards to market. Mayfield expects them to be ready by the end of spring.The flip flops are currently in the prototype stage. Mayfield plans to distribute several pairs to UCSD students this summer for testing. He hopes they will be ready for sale to the public by next year."My dream would be if we could make all the flip-flops in the world out of this material. This would have an enormous benefit to the planet."Mayfield's team are experimenting with the chemistry to control how quickly the flip-flops will biodegrade. His plan is to engineer them to last the same as a standard flip-flop. 1531

SAN DIEGO (KGTV) - An injured cyclist is searching for answers along with some items that disappeared after a possible hit-and-run crash Monday.Rick Cessinger started biking from Ocean Beach to his home in Mission Beach around 4 p.m. Monday after leaving the home of his friend, Janet Kelleher."He put his backpack and helmet on, and rides off," said Kelleher.The handyman biked down Catalina Boulevard. About a mile and a half away, there was a crash near the intersection of Catalina Boulevard and Tennyson Street, leaving Cessinger unconscious. A day later, Cessinger woke up in a hospital with six broken ribs, a fractured collarbone, a punctured lung, and little memory of what happened.A photo of the bike helmet reveals it was cracked in the back. Kelleher retired from a career in law enforcement."It seems to me he was hit from the back and ejected off the bike ... It's bad. It's disgraceful. How does someone hit someone and drive off?" said Kelleher.That question is just one of many. Here's another one: Was Cessinger also robbed? Paramedics left Cessinger a bag with his helmet and shoes. His backpack, containing his wallet and phone, is missing. Kelleher called police."They checked, and there was no property impounded associated with the report number," said Kelleher.A Gofundme campaign has been set up to help with Cessinger's expenses.Anyone with information on the case is asked to call San Diego Police at 619-531-2000. 1450

SAN DIEGO (KGTV) - An Ocean Beach man says he was home when two burglars in a white Mercedes-Benz were raiding his garage and stealing his vehicle.      Along Lotus Street last week around 1:30 in the afternoon, Evan Montoya was in his upstairs bedroom and never heard a thing.  But when he later went down to the garage, he noticed some things were out of place and his car keys were gone.  Outside, the car belonging to Montoya - an Uber and Lyft driver - was nowhere to be found."My heart sank into the pit of my stomach.  That's my livelihood.  They took my entire world when they took my car," said Montoya.But that was hardly the entire loss.  Montoya believes the intruders slipped under the garage door - left open because the garage gets hot - before grabbing anything electric."Basically they went on a shopping spree through our garage and took whatever they wanted," said Montoya.  After the break-in, a neighbor handed him surveillance video showing a white Mercedes sedan stopping in the alley in front of the garage.  In the video, a man and a woman are seen going back and forth to their garage, before they finally drive off."Makes you feel unsafe in your home, which is the one place you're supposed to feel safe," said Montoya.Montoya's car was found abandoned a few days later.  Meanwhile, the video has been shared by neighbors across social media.  Some seven other neighbors have reported similar, recent break-ins. "People going through alleys stealing from houses," said Montoya.If you have any information on the cases, call Crimestoppers at 888-580-8477. 1659
