SAN DIEGO (KGTV) — Two girls were rescued at Sunset Cliffs by teenage bystanders on Friday after being swept out to sea.Local still photographer Jim Grant was hoping to capture the sunset at Sunset Cliffs Friday evening. But he got much more than just a beauty shot."There were some crazy things going on," Grant said.He ended up witnessing a cliff and water rescue."Two young girls ... They looked to be about 12 or 13," Grant said. "They were down at this point, and a large set came in and swept them off their feet.""The older one hit her head probably down on the reef and had a pretty serious head injury in the water," Lt. Andy Lerum with the San Diego Lifeguards said.Before first responders could arrive on the scene, two boys jumped into the water to help the girls. The two teenage boys worked to keep the girls above water until help arrived, lifeguards said, adding that their efforts were instrumental in saving their lives."It was big surf," Grant remembered. "The girls could not swim or couldn't swim very well, that's for sure. And it just could've been a tragic event if those two guys didn't happen to be here."Grant captured dramatic photos of the rescue, showing responders hoist one of the girls from the cliffs. In the end, Grant did get his sunset shot, just with an amazing cliff rescue in the foreground.Lifeguards remind folks that even in exposed reef areas, strong waves could come crashing at any moment. So take extra precautions when going into the water this weekend. 1509

SAN DIEGO (KGTV)- A new effort is underway to revive a San Diego public golf course that's falling apart.  The "Friends of Presidio Hills Golf" went before the city council Tuesday urging them to take up the issue.  Their plan is to restore the course to its former glory days.Presidio Hills in Old Town is a local golf course with a storied past and an uncertain future."It needs to be completely redone," said John Vallas, who spearheaded the proposal.The place many once called the "cradle of golf" in San Diego is now a long shot from being up to par. 578

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) -- While the visible reminders of local wildfires may be gone, San Diego fire officials say what’s left over can still cause a lot of problems especially as the region expects to get rain this weekend.After an intense wildfire happens, the burned vegetation and charred soil forms a water repellant layer that blocks water absorption -- which means the next time it rains, there’s potential for flooding.Cal Fire wants to remind residents to prepare before the rain arrives.Thomas Shoots, a spokesperson for Cal Fire, said, “Anyone near the Valley Fire needs to be prepared for any type of debris or mud flows. They need to have sandbags and the area around their home prepped so that everything looks OK.”In September, the county gave residents free supplies to make sandbags so people could begin their preps for the rainy season.County information on free sandbag availability can be found here.The City of San Diego is also offering sandbags for residents. They’ll be giving them out at select locations on Friday from 1 p.m.-7 p.m., and this weekend from 12 p.m.-2 p.m. Click here for information on city sandbag availability.Anyone who picks up sandbags is asked to wear a mask and have an ID ready. 1230

SAN DIEGO (KGTV) - When school started last week at Dailard Elementary in San Carlos, the father of a second grade student noticed several large spiders and egg sacks in the area where kids hang their backpacks. He took several photos documenting the issue. When he reached out to 10News about a week later, he said he had already spoken to a teacher, custodian, and the principal about the issue but was told a work order would need to be put in to get pest control to the school. The same parent said the spiders appeared to be brown widows, which are venomous and a bite from one requires medical attention. A San Diego Unified School District spokesperson confirmed that a pest control team was sent to the school Thursday to get rid of the spiders and eggs. They also confirmed that the spiders were indeed brown widows, very common in the San Diego area. Despite the concerns, there were no reports of any children ever being bitten. 952
