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) – Fixing San Diego’s streets was one of Mayor Kevin Faulconer’s top priorities when he took office, and now he believes they’re on schedule to reach his goal of repairing more than 3,000 miles of roads.About a decade ago, it took crews an entire year to get about 24 miles of street repairs done in the city. Now, crews are averaging 25 miles of street repair a month.Kris McFadden, director of San Diego’s Transportation & Storm Water Department, said the pandemic helped them get the work done without causing much backups on the roads.“We staggered working times, people coming in different times. So, we were able to do a lot of repairs, especially when people weren’t driving on the roads,” said McFadden.Faulconer said, “When I ran for mayor, there was no issue that San Diegans complained about more than streets, so we have been on a mission over the past six years to bring smooth streets to neighborhoods across the city. We overhauled the repair program to speed up fixes, made record investments in street repair, and are on pace to fix half of all City streets by the end of the year. The robust program we now have in place fixes hundreds of miles annually and I strongly encourage the next Mayor to keep the pedal to the metal until every San Diegan can experience a freshly paved street outside their front door.”In a news release, city officials said crews “completed repair work on some of the City’s busiest streets including completing repairs to North Harbor Drive, Fairmont Avenue, Montezuma Road, and a network of streets in Mission Bay that have not seen a major facelift in nearly two decades. Construction on Scripps Poway Parkway is underway and anticipated to be completed in December.”Even though the city is on track to repave half of the its entire street network by the end of the year, City Councilmember Vivian Moreno said there’s more work that needs to be done, specifically on dirt and gravel roads in neighborhoods like Stockton.Moreno sent ABC 10News a statement that read, in part: “These dirt streets are vestiges of the past maintained by policies that are over six decades old.”The city says they’re looking at this request, but the plan is to finish the repairs that have already been scheduled to meet the goal by the end of the year. 2308

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

"We have to really recommit and refocus ourselves to adapting to the reality we face," Supervisor Nathan Fletcher said.Under the state's metrics, counties are placed on the list after any one of the following thresholds is met for three days in a row:Average number of tests per day is less than 150 per 100,000 residentsCase rate over 14 days per 100,000 residents is greater than 100 cases OR greater than 25 cases with a 7-day percent of testing positivity equal or above 8%Greater than 10% increase in three-day average of COVID-19 hospitalized patientsLess than 20% of ICU beds available or less than 25% or ventilator availableSan Diego County crossed the case rate metric on June 30 with 105 cases per 100,000 residents. Here are San Diego County's numbers as of Wednesday: 1152
