SAN DIEGO (KGTV) - If you look up to the early morning sky on next week, there's a good chance you'll catch NASA's rocket launch.NASA's InSight is scheduled to launch May 5 from Vandenberg Air Force Base in California between 4:05 a.m. and 6:05 a.m., weather permitting. The launch will be NASA's first interplanetary launch on the West Coast.Insight will launch atop an Atlas V rocket, one of the biggest available to make the 301-million mile voyage.And if you live in Southern California, you'll have a front-row seat.RELATED: SpaceX rocket launch seen above San Diego"If you live on the California Central Coast or south to L.A. and San Diego, be sure to get up early on May 5th, because Atlas V is the gold standard in launch vehicles and it can put on a great show," Tim Dunn, launch director for the Launch Services Program at the John F. Kennedy Space Center in Florida, said.If the launch is scraped, NASA has given a six-month time window to set InSight for Mars. Whenever InSight launches in this window, it would be scheduled to arrive at Mars Nov. 26, 2018, around 12 p.m."If you live in Southern California and the weather is right, you'll probably have a better view of the launch than I will," said Tom Hoffman, project manager for NASA's InSight mission, who will be in the control room during launch.RELATED: SpaceX?launches NASA'S planet-seeking satelliteInSight will deliver a lander and two satellites to the Red Planet to investigate how the planet was formed and has evolved over time. It will also measure Mar's seismic activity and how meteorites have affected the planet.The mission is estimated to last about two years. 1699

SAN DIEGO (KGTV) — In the race for a coronavirus vaccine, scientists often say we need more than one winner.That’s in part because different vaccines use different strategies to provoke the immune system, and each strategy has different strengths.Take the inactivated virus vaccine, an approach currently used in the vaccine against the poliovirus. In this approach, scientists take a live virus, kill it with chemicals or heat, and then introduce that viral corpse into a person.There are three groups in the final phase of human trials using inactivated coronavirus, primarily in China, according to a tracker from the Milken Institute.“The immune system can tell the difference between something that's a real threat and something that's not a threat, and so if you get injected with a dead virus your immune system has the tendency to not pay a lot of attention to that,” said Dr. Shane Crotty of the La Jolla Institute for Immunology.The downside of the inactivated virus approach is that it only elicits two out of the three of the parts of the immune system, Dr. Crotty said. It’s capable of producing antibodies and helper T-cells, but not killer T-cells.The modern take on the inactivated virus approach is called a viral vector vaccine.In this strategy, scientists combine elements of the coronavirus with a common cold virus called an adenovirus that won’t make you sick. Since the virus is alive, it can elicit all three kinds of immune responses, Dr. Crotty said.“There are no licensed vaccines right now that use that strategy, but there are all kinds of vaccine trials that have been done around the world with those types [of vaccines] showing that they're straightforward to manufacture. They're very safe,” he said.The University of Oxford is testing a viral vector vaccine for COVID-19 in a Phase 3 clinical trial.Then there are subunit vaccines. These include just a section -- or subunit -- of the virus’ protein.UC San Diego is working on a coronavirus candidate vaccine using this approach.There are subunit vaccines currently on the market for tetanus and other viruses.“Working with proteins is more challenging, just from a laboratory and manufacturing perspective,” Dr. Crotty said.Enter the next phase of vaccine development. Instead of using the virus itself or fragments of it, Inovio Pharmaceuticals is working on a vaccine strategy using just the virus’ genetic information.DNA-based vaccines simply introduce a genetically engineered blueprint of the virus into a person, and the cells do the rest.“Some people get confused about this. They think it’s a genetic vaccine that changes their DNA and becomes part of them, and that’s definitely not the case.” Dr. Crotty said. “They don’t become part of you. Your body chews them up.”Researchers have been working on DNA-based vaccines for about 20 years, Crotty said, but none are currently licensed for use.San Diego-based Arcturus Therapeutics is using an RNA-based approach, along with other companies like Pfizer and Moderna that have entered Phase 3 trials.Messenger RNA reads the DNA instructions and helps translate them into proteins.Dr. Crotty said the DNA and RNA approaches have similar drawbacks and benefits: they’ve never been approved for us, but both can be developed rapidly because they don’t require access to the physical virus.Around the world, there are more than 200 coronavirus vaccines currently in development, according to the Milken Institute. 3459

SAN DIEGO (KGTV) -- Kristin Elliott is CEO of Precision Engineering in Vista, a company that creates water quality sensors for oceans and lakes, "we sell these to universities around the world, work with Scripps Institution of Oceanography," Elliott described.Her work is her passion but so is her team, so when the pandemic hit she said it was her goal not to layoff any employees, taking a pay cut so her team could stay paid."We wanted to save our team through this," she said. Then, there was the announcement kids would be returning to school online."We have this space that we're not gonna be utilizing because no one's having in-person conferences, we're all over zoom these days," turning the room into a classroom. "It's large enough to fit 3 or 4 kids and that's exactly the number of kids we have with our employees. We're going to have a little reading area where kids can switch places to relax and reset. All the things you can normally find in a classroom, a bookshelf with all the interests they might have." Elliott even went to great lengths, hiring an accredited teacher's assistance to help."It's definitely a relief. I know they were just thinking about homeschooling and working, trying to manage that. There's so many emotions involved and so much anxiety and stress, and my goal was to reduce that for our employees."Elliott has followed all CDC protocols and guidelines for her 15 employees working in office, and she'll do the same when their kids come fall."We're still getting the room set up because we want to ensure social distancing between the children and the teacher. We're also bringing in the PPE that the CDC is requiring and kind of recommending for opening these." 1712

  

SAN DIEGO (KGTV) -- It's a question some are grappling with as COVID-19 cases surge across the country.In June, a woman posted a picture of a San Diego barista on Facebook with the caption "Meet Lenen from Starbucks who refused to serve me cause I'm not wearing a mask. Next time I will wait for cops and bring a medical exemption."Someone started a GoFundMe for the Starbucks barista who went viral and has raised 0,000 in donations.Also last month, a woman went on a tirade after being asked to wear a face covering in a Trader Joe's store in North Hollywood.There's no shortage of stories about public debates over face masks.RELATED: New UCSD finding: Wearing masks significantly curbs spread of COVID-19In California, people are required to wear face coverings in most indoor settings and outdoors when physical distancing isn't possible.According to a Pew Research Center study conducted in early June, "Overall, 65% of U.S. adults say that they have personally worn a mask in stores or other businesses all or most of the time in the past month, while 15% say they did this some of the time. Relatively small shares of adults say they hardly ever (9%) or never (7%) wore a mask in the past month, and 4% say they have not gone to these types of places."Reporter Adam Racusin spoke with two doctors in different parts of California to get their take on masks."The primary purpose of wearing a face covering is to protect other people in case you're one of the probably significant number of people who are shedding the virus and not have symptoms," said Dr. Dean Winslow, a professor of medicine at the Stanford University Medical Center.Winslow said the risk of coming into contact with the virus is higher when in indoor settings.RELATED: Some San Diegans push for end of San Diego County face mask requirement"Historically, the major outbreaks we've seen we know where the point source is, and have almost always been indoors," he said."Eventually, the people around us, how healthy they are, is going to come back to haunt us," said Dr. Jyotu Sandhu, Family Medicine, Sharp Rees-Stealy Medical Group. "So we need to look at mitigating the risk for everybody, and masks – regardless of the type – can reduce the risk of spread.”Sandhu said the goal is to lessen or reduce the spread of COVID-19."They (people) want to hear a black or white answer, are masks good, or are they not good, are they protecting me? Are they not protecting me? And it's really a gray area," he said. "They are protecting you, but they are not 100 percent preventative."So, what's behind the decision not to wear a mask, and what are people thinking?RELATED: 8 mask hacks to follow rules while staying comfortable"What we're talking about is the curtailing of folks’ freedom," said Dr. Saurabh Gupta with Southern Californian Psychology Centers.Gupta said some of the factors influencing decisions are world experience, how people see their political leaders, and social responsibility."It's worth looking at people on kind of a spectrum," he said. "So there's some people who really appreciate the mask and recognize that their social responsibility dictates, they really care about other people, they want to make sure that if inadvertently they are infected they don't want to pass it on to anyone, gosh they would feel terrible about that. Then you have folks on the other end who just don't want their freedom curtailed in any way. They don't want to be told what to do, and to cover their face feels very personal. And then you have folks everywhere in between in that spectrum. They will say, alright, I'll put up with this if I have to, but as soon as I don't have to or I'm not being told to it's coming off because I don't like it on my face.”In a UCSD campus-released article titled "To wear a mask or not, is not the question; Research indicates it's the answer," Chemistry Nobel Laureate and UCSD Professor Mario Molina shows the data does not lie.A pivotal point of the study was when they looked at the numbers in Italy and New York after their respective mask mandates went into effect on April 6, 2020, and April 17, 2020. It was only then that the spread of viral air particles slowed drastically. 4211
