SAN DIEGO (KGTV) — It's become the first question when considering a cell phone plan: How's the coverage?In San Diego, AT&T customers may find they have better luck than other carriers, according to a study by PC Mag.Locally, 19 locations were tested around the county — from Chula Vista to La Jolla and out to the College East area — between May 7 and June 1, 2019. Testers ran speed software every two minutes on sets of Samsung Galaxy S10 series phones for about 15 minutes in each location.For San Diego County, AT&T scored the "fastest" title ahead of T-Mobile, Verizon, and Sprint."In San Diego, AT&T had nearly double the average download speed of the next-fastest network, with excellent reliability," PC Mag writes. "The carrier has been spreading its 5G Evolution LTE improvements up and down the California coastline, and we really saw the positive benefits this year."AT&T's average download speed was recorded at 90.7 Mbps, compared to Sprint's 51.5 Mbps, T-Mobile's 44.2 Mbps, and Verizon's 36.4 Mbps averages. Uploads over 2 Mbps were successful 97% of the time on AT&T's network, 96% on Verizon, 94% on T-Mobile, and 74% on Sprint.Overall, AT&T, T-Mobile, and Verizon were all given a 100% reliability score. But when it came to speed of network, AT&T grabbed a perfect score, followed by T-Mobile, Verizon, and Sprint."AT&T and Verizon both plan to bring 5G to San Diego this year. As they're millimeter wave networks, you should expect to see them in dense parts of downtown and the Gaslamp District; you'll be relying on 4G in most of the sprawling San Diego metro area for years to come," PC Mag writes.PC Mag's full study and methodology can be found here. 1717

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) — In their push to reopen schools, some political supporters of President Donald Trump have cited COVID-19 research from a group of San Diego scientists, claiming it’s evidence we could be close to herd immunity from the virus.But one of the authors of that research says that conclusion is way off.One of the most prominent supporters of the herd immunity conjecture is Dr. Scott Atlas, a neuroradiologist and senior fellow at Stanford University’s Hoover Institution who became an adviser to President Trump this month.“There’s a pretty good chance that herd immunity requires way less infections because of existing immunity out there,” Atlas said in a livestream conversation with San Diego County Supervisor Jim Desmond. “It actually may have already been reached in places like New York. We don’t know, but it’s possible.”Herd immunity is the level of protection needed to effectively stop the virus from circulating, thought to be about 70 percent of the population. The “existing immunity” to which Atlas is referring has to do with T cells.“It's just a misunderstanding of the science,” said Dr. Shane Crotty, a virologist at the La Jolla Institute for Immunology who co-authored the groundbreaking research on T cells in June.Crotty and his colleagues found that 50 percent of people unexposed to the novel coronavirus had T cells that could recognize it. Scientists refer to this as cross-reactive T cells, and the study was replicated in other countries.Proponents of the herd immunity theory take the number of people infected with the coronavirus, add the number of people with T cells that can recognize the virus, and come up with a number around the herd immunity threshold of 70 percent. But the math doesn’t work that way, according to Crotty, in part because T cells only kick in once a virus has hijacked cells, meaning T cells alone can't stop a pathogen in its tracks.“We’re not saying those 50 percent of people have protection like they’ve already had the virus,” Crotty said. “We’re saying those 50 percent of people have a head start in responding to the virus, which is a good thing but doesn’t affect herd immunity.”Since the novel coronavirus is a new pathogen, scientists did not expect people would have tools in their immune system capable of recognizing it. Unexposed people do not have cross-reactive antibodies, Crotty said.But in a study published this month in Science, Dr. Crotty and his colleagues offered a potential explanation for the surprising T cell results: they found these cross-reactive T cells also recognized four other coronavirus strains that cause common colds.Their theory: the T cells were created in response to other coronaviruses but can recognize SARS-CoV-2 like a distant relative.“It's a memory of a cousin,” Dr. Crotty said.That memory may speed up the body’s immune response, which can normally take about a week for an unknown pathogen, Crotty said. But scientists aren’t sure yet what role T cells actually play in clinical outcomes.“We have no data and and neither does anybody else as to whether these T cells really help or not,” Crotty said.To answer that question, scientists would need blood samples for lots of healthy people and then they would have to closely study individuals who got infected.The La Jolla Institute for Immunology is raising money for that kind of research, Crotty said, but they’re not there yet. 3417

SAN DIEGO (KGTV) - If the flood of fellow travelers doesn't keep you close to home this Memorial Day weekend, perhaps the price at the pump will.Gasoline prices have climbed 12 cents over the past two weeks to bring the national average to about .93 per gallon before the Memorial Day weekend. It's the highest since Memorial Day 2014 when the average hit .65 a gallon, according to AAA.In California — one of 14 states above a gallon — drivers will have it the worst in the U.S. with an average of .71 a gallon.GAS PRICE MAP: Find the cheapest gasoline near you and around San DiegoSan Diego's local prices mimic the state's trend. A year ago the average for a gallon of gas in the county was about .03, compared to about .73 a gallon today.For the week ending on May 11, the Energy Information Administration (EIA) reported gas stocks fell by about 200,000 barrels to 29.7 million barrels.However, inventory levels are 600,000 stronger than this time last year. Imports increased by 50,000 barrels to 117,000 barrels last week, EIA reports.RELATED: Memorial Day weekend to see the most travelers in last 12 yearsDespite this, gas prices don't look like they'll put a dent in weekend travel.This year, AAA expects more than 41.5 million travelers to be out for Memorial Day weekend, a five percent jump from last year. Of that, about 36.6 million people will be on the roads.And drivers may need to fill up more often on top of that. Transportation analytics company INRIX predicts travel delays could be up to three times longer than normal in some areas of the country.BEFORE YOU HEAD OUT: Check updated San Diego traffic conditionsAnd as the summer rolls in, gasoline prices may not look back."Compared to an average of the last three Memorial Day weekends, pump prices are nearly 50 cents more expensive and climbing," Jeanette Casselano, an AAA spokesperson, said. "Trends are indicating that this summer is likely to bring the national average to at least /gallon." 2040
