SAN DIEGO (KGTV) — UC San Diego researchers are testing a technology that's been in development for more than a decade to fight the coronavirus.In lab experiments, "nanosponges" covered in human lung cell membranes and immune cell membranes were found to attract and neutralize the SARS-CoV-2 virus in cell culture, according to a UCSD release. This caused the virus to lose about 90% of infectivity, or its ability to hijack cells and reproduce.The tiny sponges are designed to impersonate and protect healthy cells by soaking up harmful pathogens and toxins, according to Liangfang Zhang, a nanoengineering professor at the UC San Diego Jacobs School of Engineering. RELATED: San Diego company's COVID-19 test gets emergency approvalFor example, the nanoparticle covered in membranes from cell types the virus is known to invade latch on to the virus. This prevent the virus from then entering an actual human cell."Traditionally, drug developers for infectious diseases dive deep on the details of the pathogen in order to find druggable targets. Our approach is different. We only need to know what the target cells are. And then we aim to protect the targets by creating biomimetic decoys," said Zhang.While Zhang has spent the last 10 years developing the technology, his lab turned to using the nano-particle to fight the coronavirus when the pandemic hit.RELATED: Scripps Research's antibodies study shows signs of success against coronavirusNow, the first data on the technology's ability to battle the virus is being released after testing by researchers at Boston University."Another interesting aspect of our approach is that even as SARS-CoV-2 mutates, as long as the virus can still invade the cells we are mimicking, our nanosponge approach should still work. I’m not sure this can be said for some of the vaccines and therapeutics that are currently being developed," said Zhang.UCSD researchers will test the nanosponges’ effectiveness in animal models in the next few months and are moving as fast as possible to eventually test the technology in humans. RELATED: Startup creates mobile COVID-19 testing clinic on wheelsNanosponges have a massive amount of testing ahead before they make it to human tests, Zhang said."I see potential for a preventive treatment, for a therapeutic that could be given early because once the nanosponges get in the lung, they can stay in the lung for some time," Zhang said. "If a virus comes, it could be blocked if there are nanosponges waiting for it."(Read more about the study and nanosponges here.) 2562

SAN DIEGO (KGTV) -- With the help of witnesses, a driver was arrested late Wednesday night after police said he crashed into several parked cars before taking a U-turn and crashing head-on into another vehicle.According to San Diego police, the incident began at around 11 p.m. on University Avenue in North Park.Cell phone video captured by a witness shows the driver hitting parked cars before trying to leave the scene. He then ends up on the wrong side of the street, where he then crashes into another car, the video shows.The man gets out of the car and tries to run away, but witnesses detained him until police arrived.The driver was taken to a hospital and is suspected of driving under the influence.A woman in the car hit head-on was also taken to a hospital with minor injuries. 798

SAN DIEGO (KGTV) -- USO San Diego received a 0,000 grant that has expanded several food and nutrition programs to support military families across the country who have been impacted by the pandemic. The gift was provided by The San Diego Foundation COVID-19 Community Response Fund, in large part due to funding from San Diego Gas and Electric, said the non-profit in a release."Immediately following the stay-at-home order in our county, USO San Diego recognized the importance of sustaining our food distributions," said Ashley Camac, USO San Diego's Executive Director. "We wanted our military families to be confident the resources they depended upon would remain accessible."The resources mentioned include grab-and-go bags of non-perishable items, a Thanksgiving meal kit giveaway, mobile farmers markets, and healthy breakfast options for military children participating in distance learning.Currently, SDG&E has donated .5 million to the San Diego Foundation COVID-19 Community Response Fund. The utility company plans to contribute an additional 0, 000 in early 2021."Even without factoring in the impacts of the pandemic, military families face many stressors related to deployment and make great sacrifices to serve our country," said Eugene "Mitch" Mitchell, SDG&E's vice president of state governmental and external affairs. "Food insecurity is the last thing they should have to fear."Since the pandemic, San Diego USO has served over 200,000 military members and their families. 1517

SAN DIEGO (KGTV) -- With temperatures expected to soar into the 80s and 90s along San Diego's coast this weekend, lifeguards say they'll be extra vigilant at beaches and bays."We still want people to come and enjoy the beach," said San Diego Lifeguards Lt. Rich Stropky. "But come talk to us first; We will describe the do's and don'ts and any safety issues."In addition to the usual rip currents and stingrays, lifeguards say people need to be careful about over-exertion and heat-related illness like heat stroke or dehydration.Study: Longer and more frequent heatwaves expected for Southern California"Especially if you're at a beach like Torrey Pines, where you have to hike in or hike out," said Stropky. "So, bring lots of water. Hydrate often, not just when you're thirsty. And then stay cool, get some shade and make sure that sunscreen's on."Lifeguards also say they expect big crowds, which means swimmers and boaters will have to share the water.Tragedy struck last weekend when a Jet Ski and boat collided, killing one person. Stropky said everyone needs to have a heightened sense of awareness and keep their head on a swivel."It's very very dangerous," he said. "We've had several accidents. There's no reason for these things to be happening, except for lack of awareness."RELATED: Stretch of scorching heat begins in San Diego CountyAt boat and Jet Ski rental companies, like Action Sport Rentals on Mission Bay, staff are putting extra emphasis on safety as they send people onto the water.Action Sport Rental has people fill out safety forms, watch a video produced by the San Diego Police Department, and go through one-on-one safety training before they get on the boat."Most of the time, for people out on the bay, it's very hectic," said Action Sports Rentals Manager Alexes Pelzer. "Just make sure to learn the rules of the bay and look out for things floating in the water."STAYING COOL: San Diego County opens cool zones amid heat waveAnd while the air temperature could be too hot, Stropky warns the water temperature is still very cold. Measurements this week have been in the low to mid-60s, and he said anyone who has a wet suit should wear it in the water. 2194

SAN DIEGO (KGTV) - When flames engulfed a Northern California community last month, nurses and doctors found themselves in danger.Video of a medical team evacuating patients from a Kaiser Permanente hospital in Santa Rosa shows the desperate situation.Julayne Smithson was part of the team captured in that viral video.Just moments before, her own home burned down across the street from the hospital. Smithson had recently bought the mobile home and did not have insurance. She’s now living in hotels.A YouCaring page has been established for Smithson. 561
