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) - Hiring is increasing in San Diego County with local employers adding jobs in all industries, the San Diego Workforce Partnership reported. The most recent U.S. Bureau of Labor statistics show unemployment dropped to 3 percent in April, as San Diego County gained 7,800 jobs month-over-month. The largest increase was posted in the construction field, with 2,200 jobs added. The boom was likely due to improving weather in April after an unusually rainy winter, experts said. Other growing industries included Education and Health, and Professional and Business, which added 1,000 jobs. The Government and Leisure and Hospitality fields each grew by 900 jobs. The smallest growth was reported in the Information field, with 100 jobs added in April.

SAN DIEGO (KGTV) -- For the first time in nearly 100 years, an integrated company of male and female recruits at MCRD San Diego are about to begin their journey into becoming Marines. These future Marines will be led by graduates from MCRD's first ever integrated Drill Instructor Course. Now the mission of the course is to screen, train, and further develp leadership and command presence of selected Marines, in order to successfully perform duties of a drill instructor."We are taking them from the leadership skills, that they had in the fleet, and further refining them here," says Major Lynn Stow, Director of the MCRD San Diego Drill Instructor Course. "The drill instructor's goal is to successfully transfer recruits into United States Marines."Fifty-seven Marines are scheduled to graduate from the grueling 57 day course, and for the very first time, the graduating class will include 3 females."Getting the opportunity to come here was almost like divine intervention, everything just kind of fell into place," says student Sargent Stephanie Fahl. "To come here and make it this far, I'm really proud of myself."These future drill instructors at MCRD are looking forward to changing the lives of young 17 and 18-year-old recruits. "The change I'd like to instill in the recruits is to obviously maintain that discipline that's a staple of recruit training,"says student Sargent Stephanie Jordi. "I'd also like to inspire them and teach them how to become leaders even from that lowest level." Student Sargent Ikea Kaufman feels being a drill instructor is about teaching recruits how to be men and women."There is more to life than social media and all that. There is actually responsibility."And while Drill Instructor Course is very rigorous, the payback is immense. "You have contributed to the mission of making Marines. You have been able to take these recruits from day one and transform them into Marines. They are going to look up to you as their role model." 1991

SAN DIEGO (KGTV) -- Despite carefully measured protocols for distance learning and on-campus housing, San Diego State University is continuing to see new cases of coronavirus among students.SDSU ended its first week of the fall semester Friday announcing three new cases of COVID-19. Since the start of the 2020-21 school year, SDSU has reported seven positive cases.The unidentified students all live off-campus and were only on campus to seek testing at the Student Health Services Outdoor COVID-19 Test Collection Booth, university officials said. The three students did not interact with any SDSU employees or spaces outside of the SHS, according to officials."We have quickly identified and are speaking with the individuals known to have been in direct contact with these students. All are following established public health protocols for isolation and quarantine, and exposure risk to others on campus is deemed low," said Libby Skiles, Ed.D., SDSU Student Health Services Director.RELATED: SDSU begins 2020-21 school year with mostly virtual classesOfficials said that two of the three students are connected to one of the student cases confirmed Thursday. The third new case is linked to another case confirmed Wednesday."It is important to clarify that the three cases [confirmed Friday], together, are not all connected," said Skiles. "Further, due to their connection to previously reported positive cases, all of these individuals were already quarantining in compliance with public health guidelines."The campus opened this week to strict safety guidelines and almost all online classes in their effort to prevent the spread of coronavirus. The campus slashed available on-campus dorms to less than 50%, fraternities imposed their own bans on social events, and fall sports were postponed.San Diego State: Two students test positive for COVID-19; Risk to campus 'low'However, the campus isn't completely closed to students. In addition to the 2,600 students living on-campus, hundreds more students are likely to visit the campus for certain matters over the course of the semester.According to a university spokesperson, officials have administered 171 COVID-19 tests between Aug. 11 and Aug. 27, and have confirmed 7 positive tests.Since the start of fall 2020 classes, on August 24, the average number of tests administered per day is 36, according to the spokesperson. 2395
