SAN DIEGO (KGTV) -- Photos captured along the shores of San Diego show the return of a bioluminescent glow cause by a phenomenon known as the red tide. Pictures posted on social media show the eerie neon glow. According to several San Diego photographers who captured the phenomenon, the bioluminescence was captured along the shores of La Jolla and Torrey Pines State Beach Wednesday night. The glow is created by an algae bloom called the red tide. The algae bloom is filled with phytoplankton called "dinoflagellates.” The organisms react with bioluminescence when jostled by the moving water. "Where the wave crashes onto the shore, as it rolls over that’s where the turbulence is highest," said Clarissa Anderson at The Scripps Instutition of Oceanography. "That’s why those are really bright stripes of light. We don’t know the exact smoking gun yet. It’s a certain set of environmental conditions."PHOTOS: San Diegans capture 2018 neon glow of red tideAccording to scientists, the blue glow can be created by stepping in the water or by the crash of waves. It’s unclear exactly how long this year’s red tide will last; however, an algae bloom in September of 2013 lasted a week and a bloom in October of 2011 lasted a month, researchers say.According to the Scripps Institution of Oceanography, the red color of the tide is due to the high number of organisms in the water. 1389

SAN DIEGO (KGTV) -- November is nearly here and, as millions are making Thanksgiving travel plans, we’re taking a look at the cheapest ways to get around Southern California. According to AAA, more than 54 million Americans traveled more than 50 miles for Thanksgiving in 2018. The vast majority of travelers traveled by car. Below is a comparison on how much it would cost a family of four to get from San Diego to Santa Barbara and back using various methods of transportation: Taking a TrainAhead of the busy holiday, Amtrak is increasing capacity on its Pacific Surfliner route. If you were to book your trip on October 23, the cheapest tickets for a family of four cost 6 to get there and the same to get back for a total of 2. However, if you’re trying to get there quickly, you’ll save about an hour each way by driving instead of taking the train. Taking a PlaneOf course, there’s always the option of flying. As of October 23, Google Flights lists the cheapest airfare for a family of four as 8 roundtrip. Most people, however, choose to travel by car, according to AAA, and that may be your cheapest option despite recently skyrocketing gas prices. Taking a CarThere are many cost factors to consider, including the make, model and year of your vehicle, how many miles per gallon it gets, fuel cost around Thanksgiving and traffic. So, let’s assume you drive a 2015 Kia Forte. Currently, gas is just over per gallon. Assuming you fill up twice between San Diego and Santa Barbara and twice on the trip back, fuel would cost just over 1. Even as gas prices remain extremely high compared to the national average, getting to your Thanksgiving destination by car is the cheapest option. The above estimates assume a family of four is traveling between Wednesday, November 27 and Saturday, November 30 between San Diego and Santa Barbara. Of course, prices on all methods of transportation listed above are subject to change, especially as the holiday gets closer. 1994

The suspect fled the area heading northbound.The victim was taken to a nearby hospital with non-life threatening injuries.Anyone with information is asked to call SDPD 619-531-2000 or Crime Stoppers at 888-580-8477. 661

SAN DIEGO (KGTV) — Nearly three-quarters of the students in San Diego County are currently learning from home, and those numbers don’t make a lot of sense to MIT professor Martin Bazant.Bazant is one of the creators of the COVID-19 Indoor Safety Guideline. The free online tool simulates the fluid dynamics of respiratory droplets in various kinds of rooms to show users the risk of different indoor environments.“If you run the numbers for a typical classroom, especially if the students and the teachers are wearing masks, then the amount of time in the room can be very significant,” Bazant said. “Essentially those people could spend a week in the classroom and not have a problem.”Bazant says the six-foot rule that has largely determined which businesses can stay open is overly simplistic. In some cases, he says the rule creates a false sense of security. In other situations, he says it causes the closure of businesses or schools that could safely operate.“If you place nursing home beds six feet apart in a shared room, they are absolutely not safe,” he said. But he said well-ventilated classrooms, with teachers and students in masks, are another story.“It's only the United States where we follow the six-foot rule. That's given by the CDC. The World Health Organization all along has been saying one meter, which is about three feet. If you simply followed the one-meter rule, all our schools would be open, as they are in most of the world right now,” he said.Bazant and his colleague John Bush said they set out to design a tool that would reveal the risk of transmission based on science, not guesswork.Users start by selecting a room type, like a classroom or an airplane. From there, they can control a wide array of variables to dial in the risk, like the room size, the ceiling height, and the ventilation and filtration systems.From there, users can further tune the model by human behavior. How many people are in the room? Are they whispering, shouting or singing? How many are wearing masks?Mask usage is a critical component, Bazant says. The model quickly reveals the challenges of maskless activities in rooms with poor ventilation. Put five people without masks in a 400 square foot room with closed windows, and it becomes unsafe after 33 minutes.Bazant says studies on super spreader events show in indoor environments, the distance from an infected person doesn’t matter. Infected droplets spread and mix throughout the room like second-hand smoke from a cigarette.But with masks trapping droplets and diverting them upwards like a chimney, an environment like an airplane could be safe for several hours, according to the model. With more than 95% of the passengers and crew wearing surgical masks, a Boeing 737 could support 200 people -- around full capacity depending on the configuration -- for 18 hours. 2850

SAN DIEGO (KGTV) — Poway Unified School District officials say they are going fully online for the fall school year after originally planning to give students the option for in-person instruction.In a letter to parents on Wednesday, the school district said that "stringent" standards that need to be met for in-person classes "have made it impossible for any San Diego County school district to physically reopen schools for in-person instruction before mid-September."PUSD said it planned for the possibility to resume classes in-person after the county was off the state's monitoring list for 14 consecutive days. But the requirement now requires that the county is off the watch list for 28 consecutive days, and if at any point the county exceeds the threshold for three days, it would be back on the state list and have to go through another 28-day cycle."In late Fall, we will reevaluate our plans taking into full consideration then-current public health conditions, and guidelines and restrictions from the Governor and public health department," the district said in a release. "While this information is likely to disappoint the majority of our staff and families who indicated a desire to return to on-campus learning as soon as possible, everyone should know that -- due to our extensive planning thus far -- PUSD will be ready for a prompt and safe return to in-person instruction if permitted to do so come January."The school district says its 2020-21 school year will start virtually on Sept. 2, and remain fully virtual through the December break from Dec. 21 to Jan. 1, 2021.The district adds that teachers and instructional assistants will receive additional training in virtual teaching platforms and tools in August and that the district will provide all the necessary technology for teachers and students. Parent training videos are also being developed to support families. 1905
