SAN DIEGO (KGTV) -- Residents in Pacific Beach are tired of the crime in their neighborhood. Some of them say - it's likely a lack of light that emboldens criminals. Wednesday, those neighbors brought the issue up with at a Pacific Beach Planning Group meeting, and offered a unique solution.  "Quality of life crimes are going up."Marcella Teran would know. She's lived here in the area for 30 years."We live by the Pacific Beach library, and there's so much crime over there and drug dealing," she said. "I just didn't feel safe at all."A few houses down, up in a tree above the sidewalk, Teran's neighbor took matters into his own hands."They're LED, solar powered, and it's super bright," she said, pointing out the lights her neighbor put up in front of his home. The best part is, they aren't expensive. Her neighbor purchased the lights online for less than , inspiring Teran to get a few of her own.  944

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 City Council was recently warned about the damage an earthquake can cause to the region, specifically on the county's water system."Strengthen their water system, make that long-term investment," seismologist Lucy Jones said of the city's aging water infrastructure. Jones recently spoke with city council leaders about improvements she's helped develop for Los Angeles' infrastructure."[It] contributes to a much more difficult time getting your city back up and running," Jones said.RELATED: Chula Vista native survives Alaska 7.0-magnitude earthquakeEven without a shake up, residents have seen the issues with aging water pipelines under San Diego. This month, a break to an 8-inch diameter concrete main left dozens of Hillcrest residents without water.In October, a water main break to a 90-year-old, 24-inch water transmission line in North Park flooded several streets with thousands of gallons of water. A water main break occurred in the same area in January 2017 as well.Water main breaks last August in Mission Hills, Point Loma, the Midway District, and Spring Valley also left residents and businesses without water. As of August, there had been at least 29 water main breaks around the county in 2018.Since 2013, San Diego has spent about 8 million repairing and replacing 116 miles of water transmission lines and distribution pipes, according to city documents. Though, the city still has more than 3,000 miles of pipeline to replace, San Diego Pulbic Utilities Department spokesperson Brent Eidson told 10News in August."To do it properly, we're probably always going to be replacing pipes," Eidson said.Buildings and BridgesWhen it comes to older structures throughout the county, it comes down to what standards were used when constructing a building.Geologist Pat Abbott says California has been proactive about preparing for earthquakes — he applauded the upgrades made to the Coronado Bay Bridge."You have an upright here and a horizontal road bed and they don't shake the same way," Abbott said of bridge construction. "Now we know that, so for modern bridges ... the trick is tying the horizontal and vertical together so they behave as a unit."RELATED: Alaska hit by more than 190 small earthquakes since FridayThe West Mission Bay Bridge is another such example. Dating back to the 1950s, it will soon be replaced with two parallel bridges with three travel lanes in both directions, including bike lanes. The new structure is an upgrade from its current structural deficiencies.On San Diego's preparedness, Abbott says there could be some major damages. He pointed to a similar scenario that hit San Francisco in 1989: The Loma Prieta Earthquake."Our scenario earthquake for the Rose Canyon fault, or the biggest that we reasonably expect is a 6.9," Abbott said. "If we had that earthquake we might see some major failures like [the Loma Prieta earthquake], but not widespread destruction." 2958

  

SAN DIEGO (KGTV) - San Diego County Vector Control officials reported new signs Friday of the potentially dangerous disease tularemia on a trail in Sorrento Valley.Several batches of ticks trapped along Lopez Canyon Trail tested positive for the disease, also known as rabbit fever.The first group of ticks with the disease appeared last week, officials said.County officials posted warning signs for hikers. Vector Control will also expand tick trapping in the area.The best way for people to protect themselves from tick bites include insect repellent for humans and pets, and long-sleeved shirts and pants.Tularemia can be treated with antibiotics but it can be fatal. 679
