SAN DIEGO (KGTV) -- For over a decade, SDSU associate professor of chemistry Gregory Holland has been researching spiders and particularly black widow’s silk.They’ve come to the realization, through their research, that the properties of black widow silk are stronger than steel and tougher than the Kevlar in bulletproof vests.Gregory Holland, SDSU associate professor of analytical chemistry and Northwestern chemistry professor Nathan Gianneschi said their collaboration shows the organization of the molecules involved in silk production is more complex than previously thought.There are companies that use synthetic spider silk but its the specific black widow spider silk that has the top tier benefits.“The synthetic spider silk its not a bad material, its just not as good as the real thing," Holland said.Holland says the company that creates synthetic silk actually has partnerships with Adidas and Patagonia. "The most important thing is a spider does it low energy, environmentally friendly. It’s just protein water and salt”.Once they reach the point where they’re able to identically replicate the silk of a black widow spider, the artificial version could be used in building materials for bridges or environmentally friendly replacements for plastic.Black widows (Latrodectus hesperus) spin a lightweight thread much stronger than that of other spider species, with draglines that can stretch an extra 25 percent of their length before snapping.The composition of the spun silk fibers was previously identified, but the structure of the proteins involved in producing them has been more of a mystery, now one step closer. 1650

SAN DIEGO (KGTV) - Fed up homeowners' associations are now turning to a local licensed private investigator for help with catching homeowners who are breaking HOA rules by renting out their homes on short-term vacation rental sites such as Airbnb, VRBO and Craigslist.  “I admittedly watched a lot of Magnum, P. I. growing up,” jokes Nick Bradley of San Diego’s Bradley Investigative Services.  In the last 6 months, Bradley has taken on a new field of investigative work. He and his associates are being hired by HOAs to investigate homeowners and tenants who are violating HOA bylaws and CC&Rs that prohibit turning units into short-term vacation rentals.   Bradley gave 10News an exclusive interview about this new area of detective work. He declined to offer us specifics about how he executes his investigations into short-term rental violators. We ask, “Do you ever pose as a guest and do you do surveillance work?” Bradley replies, “No comment.” “My initial thought was [to laugh],” says San Diego attorney Dan Zimberoff. He represents homeowners and has previously represented HOAs. Zimberoff thinks it’s an extreme measure for HOAs to hire private investigators, but he understands why there’s so much passion over short-term rentals. “I think what makes this issue a little different [from others] is the dollars at stake, especially in San Diego. Some of these units can go for multiple hundreds of dollars a night or thousands of dollars. People care,” he adds.  According to Airbnb, San Diego is the second ranking city in the state for Airbnb guests, after Los Angeles. Per Airbnb, in 2017 there were 537,000 guest arrivals in San Diego, generating 0 million in host income. “Right now, it’s too lucrative for [homeowners] to not do this,” says Bradley. The short-term rental fight in America’s finest city continues to be ugly. The city attorney has deemed short-term rentals illegal, per code. Meanwhile, the city council is delaying discussions over how to regulate them. Even so, certain HOAs have rules prohibiting them. The fines for violators can be astronomical. “It’s been ,000 per occurrence in some situations,” adds Bradley. If fines don’t work, court is another option. In 2012, The Mark condominium owners association filed a lawsuit against Thomas Stevens, a former condo owner, accusing him of violating the association’s policies about short-term rentals. He then had to pay out more than 0,000 after a judge ruled that he violated The Mark’s policies.  Bradley can help gather the evidence that HOAs need to litigate. “When [HOAs] go to court, my documentation and reporting will basically count as expert witness testimony for our side,” he says.  Zimberoff thinks it’s time for HOAs to consider allowing short-term rentals, but with reasonable and efficient regulations to curb nuisances, like excessive partying. “Instead of spending that energy trying to catch [a homeowner], let’s try to think of a long-term fix,” he adds. For more information about Bradley Investigative Services click here.For more information about Dan Zimberoff click here. 3193

SAN DIEGO (KGTV) - Food banks across San Diego say demand is up, and volunteering is down as the Coronavirus pandemic spreads."There are a lot of unknowns right now," says James Floros, the CEO of the Jacobs and Cushman San Diego Food Bank.Floros says they've already had dozens of volunteer groups cancel their upcoming shifts, as the CDC and state and local governments advise against any large gatherings.Meanwhile, he says demand is skyrocketing, since many people are losing money from reduced shifts, or losing access to meals they get from work, communal gatherings or other places."We know a lot of the service industry are getting laid off, school closures, what have you," says Floros. "So, we're creating our plans to ramp up our service to the community."The Food Bank serves 350,000 people a year, providing food to numerous outreach groups who then distribute it to people who are food insecure.But as distributions become harder to coordinate with new social distancing guidelines, groups are having to rethink the way they get food to those who need it."we have to reinvent the paradigm and figure out ways to get food to people who are self-isolating," says Vince Hall, the CEO of Feeding San Diego. "Because they're complying with the edicts of health officials, but they're cut off from the food that keeps them healthy."Hall says his group has canceled all group volunteer events. But they're still allowing people to volunteer on an individual basis to help deliver food.The food banks also encourage donations."It makes me sad," says Hall. "Tragically, there are going to be more people in this community struggling with hunger because people can't go to work while they stay home to take care of kids while they can't go to school and there are going to be ripple effects throughout the economy."However, both Hall and Floros are hopeful that the community will make sure hunger doesn't compound the impact of the Coronavirus."We're not panicking, we're just rising to the occasion," says Floros."This is a moment when this community is going to come together, pull together, and bring resources to bear on a problem that's going to affect people across the entirety of the county," says Hall.To donate, go to feedingsandiego.org or sandiegofoodbank.org. 2285

SAN DIEGO (KGTV) -- Fire crews battled several spot fires that popped up near Interstate 8 in Alpine Thursday afternoon.The vegetation fire, called the Victoria Fire, started near I-8 and Victoria Drive around 4 p.m., heavily impacting traffic in the area.Crews from Cal Fire San Diego and other fire agencies attacked the flames from the ground and air and were able to get a handle on the blaze by 5:30 p.m.All eastbound lanes of I-8 at Willows Road were shut down for a few hours as fire crews worked. The lanes reopened before 8 p.m.While the Victoria Fire only grew to two acres, it left some families on edge as the heat continues throughout the week.An excessive heat warning goes into effect Friday through Monday for the inland areas to the deserts. A spokesperson for Cal Fire San Diego said they are fully staffed to handle any fires that may happen.The cause of the Victoria Fire is still under investigation. 929

SAN DIEGO (KGTV) - Health experts are weighing in after a local nurse tested positive for COVID-19 more than a week after receiving the Pfizer vaccine.In a Facebook message posted on December 18, Matthew W., an ER nurse at at two different local hospitals, talked about receiving the Pfizer vaccine that day. He told ABC 10News his arm was sore for a day but he suffered no other side effects.Six days later on Christmas Eve -- after working a shift in the COVID-19 unit -- he became sick. He got the chills and later came down with muscle aches and fatigue.The day after Christmas, he went to a drive-up hospital testing site and tested positive for COVID-19."It's not unexpected at all. If you work through the numbers, this is exactly what we’d expect to happen if someone was exposed," said Dr. Christian Ramers, an infectious disease specialist with Family Health Centers of San Diego. He serves on the clinical advisory panel for the county’s vaccine rollout.He points out, it is possible Matthew was infected before receiving the vaccine, as the incubation period may be as much as two weeks. Dr. Ramers says if Matthew did contract it after the vaccine, it’s still in line with what we know."We know from the vaccine clinical trials that it’s going to take about 10 to 14 days for you to start to develop protection from the vaccine," said Dr. Ramers.Dr. Ramers says he knows of several other local cases where health care workers became infected around the time they received the vaccine. He says all the cases illustrate the fact that results aren’t immediate. Even after you start receiving some protection, it won't be full protection."That first dose we think gives you somewhere around 50%, and you need that second dose to get up to 95%," said Dr. Ramers.Dr. Ramers says Matthew’s story also shows that even with vaccines, the pandemic isn’t going to turn around instantly."You hear heath practitioners being very optimistic about it being the beginning of the end, but it’s going to be a slow roll, weeks to months as we roll out the vaccine," said Dr. Ramers.He adds this case is a good reminder of why masks, handwashing, and other COVID protocols are important, even after receiving the vaccine.Matthew says he’s feeling better since his symptoms peaked on Christmas Day but still feels fatigued. 2323
