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.

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) -- A heated debate broke out Tuesday night, as San Diego County parents discussed the rising number of school threats. One of the latest -- hateful, spray painted messages threatening violence at Rancho Bernardo High School. RELATED: Police investigate threatening messages at Rancho Bernardo High SchoolAn act of vandalism so terrifying, the school stepped up to help police find the person behind it. They are offering a ,000 reward to anyone who has information that leads to the arrest of the suspect, said Principal David LeMaster. "It starts at home, guys," said one parent. "Stop pointing the fingers at them and step up for yourself and know what your child is doing." There is still a lot of fear in at the school. It's only been one day since someone painted the threatening around campus. Words like "school shooting, Florida was nothing" and "murder, blood, chaos" have parents questioning the safety of their children."These images are quite frightening to be honest with you," Michelle Perry said. Her 15-year-old daughter texted her that morning after she saw the graffiti. "I immediately texted (my daughter) back. I texted her the pictures, I said 'you need to go to the office. You need to figure out what's going on.'"Perry attended the school meeting Tuesday night to talk more about how parents and faculty are going to keep their kids safe. Principal David LeMaster calls the message a hate crime and terroristic threats -- saying the school is working with police to catch the person who did it. A second meeting will be held at the school Thursday at 3 p.m. Parents hope to continue the conversation and brainstorm ways to make sure students stay safe.     1817

SAN DIEGO (KGTV) -- U.S Customs and Border Protection apprehended two suspects wanted in connection to both an attempted homicide and a homicide Wednesday afternoon. According to CBP, the incident began Wednesday around 3:30 p.m. at the Otay Mesa Port of Entry after a 35-year-old U.S. citizen entered the crossing with two other U.S. citizen passengers, a 37-year-old man and a 20-year-old woman. The vehicle was escorted to a secure location for processing after officers were alerted that one of the travelers was wanted. After investigating the situation, officers learned that the driver, Monica Cecilia Jimenez was wanted for attempted murder and Omar Alapizco was wanted for homicide by the Oceanside Police Department for the same crime. U.S. Marshals and the Oceanside Police Department responded and took custody of both Jimenez and Alapizco. 861

SAN DIEGO (KGTV) — U.S. Secretary of Education Betsy DeVos made an unpublicized visit to a Poway Unified School District campus on Thursday. DeVos spent about two hours at the Design 39 campus in 4S Ranch, speaking to administrators, teachers, and students. "The questions she was asking kids was, 'Really, tell me about your learning, and what do you really enjoy about learning here? How has this helped you as a learner?'" said Megan Power, a teacher at the school and former Education Department fellow who helped arrange for the visit. DeVos is a polarizing figure in the Trump administration, partially for her stance on school choice. Opponents accuse her of wanting to pull money out of public schools to pay for private education.Poway Unified Superintendent Marian Kim-Phelps posted pictures on Facebook after the visit. Some parents blasted the district for even hosting her. One woman said if she had known she would have protested outside. Another called DeVos dangerous to public education.Other parents disagreed, saying politics aside, her visit was an honor."Just the fact that she came here to visit, someone of that high a profile speaks volumes to the school," said Matt Kolker, who was picking up his son from Design 39 campus Friday. Power, who had told DeVos about Design 39 during her fellowship, said it was a great opportunity."If we want the secretary to have a better understanding of what's going on in schools, we have to be able to invite her and the team into schools," she said. Superintendent Kim-Phelps called DeVos's visit a chance to advocate for the district and public education overall.Design 39 emphasizes design thinking, which it describes as "a creative, problem solving process which helps people design meaningful solutions."In a statement, education Press Secretary Liz Hill called Design 39 "a stellar example of rethinking education to meet the needs of students." She said DeVos was thrilled to learn more about their innovative approach. 1997
