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) -- If you've ever gone out in the Gaslamp, you know how busy it can get. Nothing will ruin your night more than finding out your car's been towed.That's exactly what's happened more than 1,000 times since the city converted Fifth Avenue to a three-minute passenger loading zone after 8 p.m. on Friday and Saturday nights in September 2016. "They really don't ask questions around here," said Vanessa Figueroa, who hands out fliers for Gaslamp BBQ on the corner of 5th and Island every Friday and Saturday nights. "If you're parked here, your car's gone."The city made the change to reduce gridlock, boost emergency response times, and make passenger drop-offs safer. But that's also meant a lot of towing. In the first year, the city towed about 1,200 cars - drivers either missing the warning signs or getting confused by different ones next to each other.RELATED:  906

SAN DIEGO (KGTV) - It wasn't the opening day anyone envisioned, but by game time, foot traffic had picked up around Petco Park.It was vastly different compared to past years, according to Brant Crenshaw. He owns Social Tap San Diego, located next to the ballpark. Due to public health orders, the capacity at their restaurant was significantly reduced. However, they were able to fill the tables and chairs set up in their outdoor areas, and by the start of the game, they had a healthy waitlist.Crenshaw says despite the pandemic, Opening Day still brought more people out than usual."This is baseball. We're Americans. They go hand in hand," he said. It's definitely special and were playing the hand we're dealt."Meanwhile, there were many fans spotted decked out in game-day gear trying to catch a glimpse of the game from their balconies near the ballpark. Some fans waved Padres flags from the balcony to show support.Chip Messenger kept opening day tradition going by watching from his balcony. He has a great view of the field and has invited a small group of people to watch the game from the outdoor vantage point. He plans to share the spot with other people as the season goes on."I run a tight ship on opening day, this is my 8th or 9th opening day from my balcony," Messenger said. "So you invite people you can't have too many, but I want to start inviting people I don't know in a few days. There's going to be like some babies for the time, moms and dads, couples you know. I'll make it fun."Messenger says he usually leaves his balcony party to go to his seats at the ballpark, this year is different. But he is just happy to have baseball back after the season was delayed and shortened."It's about time," he said. 1741

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) - Mesa Biotech, based in San Diego, has received FDA approval for its rapid COVID-19 tests that can produce results in about half-an-hour.“Our first kits are going out today to some of the health systems, county health departments, to validate the performance against the existing testing,” said Laura Dullanty, a marketing manager at Mesa Biotech. She said it will still take a few weeks before they will be able to deploy them widely to the health care providers who have requested the tests. RELATED: Will you qualify for a ,200 COVID-19 stimulus check?One of the issues has been purely logistical.“In a typical manufacturing line there are a lot of people really close together. Even that's been a challenge to plan that,” said Dullanty. “We’re staggering shifts, taking time in between, cleaning the area well.” Right now, most tests are performed on-site then sent to a lab for processing. It can take several days or longer before a patient knows the results. RELATED: Dyson designs ventilator in 10 days, plans to make 15,000 of them to combat pandemicThe Mesa Biotech rapid test is based on the same PCR technology, but can be performed and processed at the point of contact, such as a hospital, urgent care clinic or a cruise ship infirmary. “We’re estimating having 5,000 - 10,000 a week,” said Dullanty on their production estimates. “Our discussion now that we are authorized is how do we scale that up?” The first batch should be shipped to providers in the next few weeks but it’s up to the health care systems to decide how and when to use them. RELATED: Company working to get FDA approval for fast COVID-19 test“There are some critical patients that maybe need the answer sooner. They are going to screen them in the ER. If it's a negative, they can release them and free up the hospital bed a day sooner,” Dullanty explained. 1871
