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) - Hundreds attended a Juneteenth event in Balboa Park Friday.The event, 'Artists 4 Black Lives,' involved local artists commemorating Juneteenth through songs and performances."It was a way to celebrate Juneteenth, mourn our fallen black brothers and sisters, and amplify our black artists' voices," The event director, Eboni Muse, said.The holiday commemorates the day in 1865 when slaves in Texas learned they were free, two and a half years after the Emancipation Proclamation was issued."As black people, it is our Independence Day. We were not freed July 4," Muse said. "I personally think it's something we need to celebrate all the time."This year's Juneteenth celebration takes place at a time when the country is engaged in a national conversation about racial injustice and police reform. The atmosphere at Balboa Park was inviting and welcoming, drawing a diverse crowd."I'm hoping our artists will open the eyes of those who see us and really understand how we feel and how this has affected our people," Muse said. 1052
