SAN DIEGO (KGTV) - San Diego Police are investigating reports of a gunfight in the city's Chollas Creek neighborhood.Police officers responded to reports of two people, described as two black males, shooting at each other in the 5000 block of Auburn Drive shortly after 1:30 p.m. Thursday.The shooting occurred on a residential street just blocks from two elementary schools: John Marshall Elementary School and The Waldorf School of San Diego.No injuries have been reported. Police have not released any information on the suspects as of yet. 571

SAN DIEGO (KGTV) — Researchers at the University of California, San Francisco are working on a spray designed to block the novel coronavirus from hijacking cells in the body, like a biological mask or internal personal protective equipment.They’re doing it by borrowing a defense mechanism from an unlikely source: llamas.The team, led by UCSF graduate student Michael Schoof, engineered a synthetic molecule based on one found in a llama’s immune system that acts like an antibody but is one-tenth the size.Human antibody treatments, known as convalescent plasma, require a transfusion in a hospital setting. But this smaller molecule, called a nanobody, can be easily self-administered via an inhaler or nasal spray and rapidly manufactured using yeast, Schoof said.The scientists named their product AeroNabs. They say it could be an inexpensive intervention for treating and preventing COVID-19 while the world waits for a vaccine.“We don't know how effective vaccines will be. We don't know how long it will take to rapidly deploy them, so we envision this product as hopefully a bridge until there is widespread, effective vaccination,” Schoof said.Once a vaccine is available, AeroNabs could offer protection for individuals who are unable to be inoculated for health reasons, he said, or an early treatment option.The team is in talks with commercial partners and hopes to begin clinical trials soon.In the 1980s, Belgian scientists discovered that about half of the antibodies in camels, llamas and alpacas are shaped differently than the antibodies found in other mammals, including humans. Researchers later learned they could use a fragment of these oddly shaped camelid antibodies to bind to antigens.Those fragments are called nanobodies.Currently, there is only one FDA-approved drug that uses nanobodies. Caplacizumab was approved last year to treat a rare blood disorder.The team at UCSF sifted through billions of nanobodies to find one that binded best to the spike proteins on the coronavirus, then engineered it to stick even better.The coronavirus uses its spikes to enter cells and replicate; the spikes are essentially the pathogen’s key into the body. By coating the spikes with nanobodies or antibodies, the viral key no longer fits into the body’s receptors and the virus can’t get in.“This works in the lab. It needs to be translated into the clinic,” said Schoof.The team at UCSF still needs to figure out the best delivery method, whether it is a nebulizer, an inhaler or a nasal spray. 2524

SAN DIEGO (KGTV) -- San Diego County needs to stay off the state watch list for two weeks straight for most schools to reopen in-person. But, some schools won’t have to wait that long.As of Friday afternoon, 56 elementary schools applied for a waiver through the county health department. If approved, it would allow them to bring students back on campus regardless of our status on the state watch list.The waiver is only open to schools serving K-6 students. Once applications are reviewed by the county they’ll be sent to Sacramento.“The state can give input or guidance,” said Supervisor Nathan Fletcher. “If we don’t hear back in three days then those will be approved.”Mt. Helix Academy in La Mesa submitted their application this week.“I’m hoping to hear back from the state and the county by next week.” Said Director, Mike Collins. “Our plan is to welcome students back on campus on Monday August 31st when we’re ready for those kids.”The school has been open for summer programs where they implemented new safety measures like masks, frequent cleaning, and social distancing.“I saw all the students had their masks on and I made a big deal, ‘Everyone has their masks on! We’re so happy!’” said Collins. “We really try to encourage our students.”For the wavier to get approved the county reviews each applicant’s proposed safety plan. They’re looking for things like having adequate personal protective equipment and if students can be kept in small groups.County Montessori School in Poway has been fine-tuning their safety measures through their summer programs.They took advantage of the waiver process right away.“The application became available last Friday night and we applied Monday,” said Head of School, Adela Corrales. “If our waiver comes through next week we’re prepared to open on site on August 24th”The county told ABC 10News they were still reviewing applications late Friday afternoon and had not sent any to the state for approval yet. 1971

SAN DIEGO (KGTV) -- San Diego Police are investigating following a deadly hit-and-run in Clairemont Wednesday night.

SAN DIEGO (KGTV) - San Diego is playing a pivotal role as a testing ground for the future border wall while the region prepares for President Trump’s visit Tuesday.WHY SAN DIEGO?The region, specifically Otay Mesa, was selected as a location for the eight prototypes because of site accessibility to construct and the ability to evaluate the wall as part of a larger, existing border infrastructure system, according to U.S. Customs and Border Protection spokesman Ralph DeSio.San Diego County’s value as a construction site was detailed in a presentation made by the Department of Homeland Security and obtained by NPR.CBP officers can compare the performance of the prototypes to underperforming existing materials in the same location, according to the document. The prototypes can also be evaluated for the impact on operations in an existing enforcement zone.The land where the prototypes are constructed is federally owned, making the project more affordable.As far as the CBP is concerned, the proof of the border wall’s success is in the pudding. A video made by the agency showed an 87 percent reduction in arrests at the border after the creation of a physical barrier.FINANCIAL IMPACT OF THE BORDER WALLSan Diego had funds earmarked for border wall construction ahead of the prototype construction. The CBP allocated 9,000 to replace the primary fence and replace the secondary fence with a wall in the 2017 fiscal year.Despite the federal green light, the San Diego City Council formally opposed the project.The group voted to support Councilmember Georgette Gómez’s proposal to oppose the Border Wall Funding Act of 2017.In her resolution, Gómez cited a San Diego Association of Governments and Caltrans study on the economic impacts of border delays on the cross-border economy. The study found the effects of border crossing delays cost .2 billion in foregone gross output and more than 62,000 jobs in both the U.S. and Mexico economies in 2007."As a city that is invested in the binational economic development of our region, it is important to oppose the building of a wall and focus our resources in enhancing our border infrastructure to ease access of goods and people," Gómez wrote.“The border wall is a huge mistake for our region economically and environmentally. I am happy the City Council voted to pass my resolution. Our tax dollars should be spent uplifting the quality of life for all San Diegans, and tackling our issues on road infrastructure, housing, and homelessness,” she said.For the immediate neighbors of the border wall prototypes, the initial impact has been positive.Otay Pizza manager Wade Aljabi said he’s had an increase in business from CBP officers and construction workers.That might change tomorrow as President Trump’s visit leads to road closures just east of his location in a strip mall at SR-905 and Siempre Viva Rd.“We’ll be open 7 to 7,” Aljabi said. 2932
