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) — Dominic Pizarro lost his mom and his little sister on Thursday, after a wrong-way driver drove into their SUV on Interstate 805. Pizarro spoke with 10News as he and his grandfather drove back to San Diego to support Dominic's older brother - who was the first to hear the tragic news. Trevor Heitmann, 18, was behind the wheel of the 2014 McLaren?sports car that collided with the SUV, killing himself, and 43-year-old Aileen Pizarro and her 12-year-old daughter, Aryana. "Both of them were the most caring...people full of life, you've ever met in the world," Pizarro said. The way his mother and sister died has dominated local news outlets since it happened.Heitmann was traveling at high speeds Thursday, heading southbound in a northbound HOV lane at about 4:30 p.m. near La Jolla Village Dr. before the collision, CHP said. Troopers believe he entered via an HOV lane access at Carol Canyon Rd. Pizarro said his family was as close as can be - the siblings were all musicians. "(Aryana) was just the most unique little girl in the whole wide world," he said. "She was your average girly girl at times, and at times she was this feisty little 12-year-old who was just so smart, so mature for her age."The siblings were raised by their mom and grandfather. Their mom Aileen was a therapist devoted to helping others.  "Everything (my mom and grandpa) had went to us," Pizarro said. "Every single dollar, every single cent was put into me and my brother and sister."Pizarro said the family will never forget their caring mother and feisty sister, as he also recalled the last conversation he had with Aryana. "She was showing me all these unicorn things she got, unicorn pencils, unicorn notebooks," he said. "She was showing me everything that she was going to wear or take to school because she was so proud of everything that mom had gotten her for school."Aryana was set to start seventh grade at the School of Creative and Performing Arts on Monday.Pizarro set up a GoFundMe page to support the family during this tough time, but also asked those aware of the story for their prayers.  2175

SAN DIEGO (KGTV) — Humpback whales aren't the only aquatic life giving locals a show off the coast of San Diego.Dolphins can be seen fairly regularly, but it's not everyday you see a pod tallying in the thousands. The term "mega" gets thrown around quite a bit to describe scale, but in this case, it truly fits.Video captured Sunday shows a "megapod" of thousands of "common dolphins" off San Diego's coast, estimated to be of about 2,500 dolphins.RELATED: Humpback whale feeding frenzy off San Diego's coastDomenic Biagini, a photographer for San Diego Whale Watch, said pods of 25 to 200 dolphins are common. But a megapod, or "superpod," refers to pods eclipsing 1,000 dolphins and may be seen once every other month."Every now and then, we'll see multiple pods come together," Biagini said. "This was like next level." 831

SAN DIEGO (KGTV) -- Hours after Navy officials said all fires aboard the USS Bonhomme Richard were extinguished, smoke was visible coming from the vessel at Naval Base San Diego early Friday morning.Radio scanner traffic obtained by ABC 10News indicated crews at the scene reported at least two fires onboard the ship and called for evacuations at around 1 a.m. Friday. The 10News Breaking News Tracker observed smoke coming from the ship’s front end.At around 5 a.m., a Navy spokesperson confirmed to ABC 10News that no evacuations were ordered and all fires were out. The spokesperson said investigators were looking into the matter.On Thursday afternoon, Navy officials said all known fires aboard the USS Bonhomme Richard were declared out. The blaze on the ship erupted on the morning of July 12, and the firefighting efforts involving hundreds of crew members and thousands of aerial water drops took four full days.Navy officials said they will not know the exact cause of the fire until the ship can be inspected fully.ABC 10News learned Chief of Naval Operations Adm. Mike Gilday will be at Naval Base San Diego on Friday to inspect the USS Bonhomme Richard.During a Thursday afternoon press briefing, Rear Adm. Philip Sobeck described the 22-year-old ship as ravaged -- its melted aluminum superstructure bent at a 45-degree angle -- but not dead in the water."The ship can be repaired," he said. "Whether or not it will be repaired will be determined."A total of 40 sailors and 23 civilian firefighters suffered various minor injuries, mostly heat exhaustion and smoke inhalation, while taking part in the battle to defeat the blaze, Navy officials said.The Bonhomme Richard is the third warship in U.S. naval history to bear the name, which means "Good Man Richard" in French and honors Benjamin Franklin's "Poor Richard's Almanac."The vessel has been homeported at Naval Base San Diego since the spring of 2018, when it returned from a six-year port switch to Sasebo, Japan, while becoming the command ship for Navy Expeditionary Strike Group Seven.City News Service contributed to this report 2114

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
