SAN DIEGO, Calif. — Scientists are harnessing a not-so-secret weapon in the fight against climate change: plants.“Plants are very good at one thing and that is to catch carbon dioxide out of the air and using the power of the sunlight to fix it to make into bio-materials," said Wolfgang Busch.A plant scientist and professor at the Salk Institute for Biological Studies, Busch is co-director of the Harnessing Plants Initiative (HPI). "Plants are superheroes," said Busch. “They can do what nothing else can do, no technical solution at that scale, to catch a lot of carbon dioxide and fix it.”Yet, humanity is still losing the climate change battle. After decades of burning fossil fuels, the planet continues to warm, with natural disasters growing more frequent and intense.Busch says while plants suck up carbon dioxide, some of it is released back into the atmosphere.“How can we actually make plants better in not only catching the carbon dioxide but keeping it in the soil?” said Busch.That's the challenge his team set out to solve, working to identify genes that help plants store more carbon underground. “Trying to enhance their superhero capability even more," said Busch. They’re developing plants with deeper, more massive roots, rich in a substance called suberin, a natural carbon storage device. Combined, these traits supercharge the plants, allowing them to absorb more carbon dioxide and keep it locked underground.“We think it has all the characteristics of something that can make a huge impact addressing this very difficult question, how to draw down carbon dioxide from the air and store it," said Busch. These climate fighting traits can then be transferred to the world’s six most prevalent crops: corn, soybean, canola, rice, wheat, and sorghum.By tapping into the existing agricultural supply chain, researchers say more than 75 percent of the world’s cropland could be converted into carbon storage.“We think in 10 to 15 years, after partnering with different stakeholders, seeds will be available to farmers at scale to plant the first carbon-sequestering crops,” said Busch.Busch says one of their top priorities is ensuring the initiative will benefit farmers, aiming to produce plants that will equal, if not exceed, the yields of current crops. And storing carbon underground not only protects the atmosphere but enriches the soil, making it more fertile.Busch says the plants will also be more resilient to climate-related threats, with an enhanced ability to hold water, resist pathogens, and tolerate stress"Gives us hope that we can make a huge impact; if we can develop crops that are better at storing carbon for longer and if these crops are adopted at a very large scale," said Busch.The initiative has received over million in grants, with the most recent boost from Amazon CEO Jeff Bezos donating million. 2867

San Diego (KGTV)- People in North Park say they’re fed up with rushing water and flood damage from recent water main breaks. There have been at least four major water main breaks, since 2017, in the same area. The latest break over the weekend was located on Myrtle Avenue near Park Villa Drive. Neighbors were left without water for almost eight hours. They tell 10News they have been trying to get the city to fix the lines in the area for years. “In the past 12 years, we’ve had seven… five on my street, two on the side streets,” says neighbor Linda Nelson. Nelson has been living in her North Park home since 1980. She says they’ve had some breaks in the same spots. “What happens is they patch it up and then a year or two later it breaks where they patched it.”The city says the concrete pipe was over 50 years old. They are in the process of replacing all cast iron pipes around the city. Then they will then assess the concrete ones. The city hopes to have all the cast iron pipes removed by 2023. But with a fast-growing community, neighbors feel the infrastructure in areas like North Park should be first on the list. “They want more apartments on the transit lines, which mean North Park,” says Nelson. “If they increase the density and they don’t fix the infrastructure that we have that just puts more pressure on it. Until they can make it right for the folks that lived here for a long time, I don’t think we need any more people.” 1457

San Diego (KGTV)--Beginning Tuesday night, Caltrans crews will close 11 on- and off-connector ramps along State Route 52 (SR-52) to repair damaged concrete slabs and replace guardrail.The closure will take place Tuesday, Wednesday and Thursday nights from 11 p.m. to 5 a.m. Crews will be working at one location at time. The following ramps could be closed during the work window.* Eastbound SR-52 to northbound and southbound Interstate 15 (I-15)* Westbound SR-52 to northbound and southbound I-15* Northbound I-15 to eastbound and westbound SR-52* Southbound I-15 to westbound SR-52* Westbound SR-52 to northbound I-15* Westbound SR-52 to southbound State Route 163 (SR-163)* Northbound SR-163 to westbound SR-52* Northbound SR-163 to eastbound SR-52Message signs will be placed in advance to each closure to alert motorists.For real-time traffic information including traffic speed, lane and road closures due to construction and maintenance activities, and more, go to http://quickmap.dot.ca.gov/ [quickmap.dot.ca.gov] 1031

  

SAN DIEGO (KGTV)---America is better with "and." It's a saying at the heart of a new experiment called itsblackandwhite.us.Ryan Berman, along with Ahab Nimry and several other marketing and advertising agency representatives say they wanted to figure out how to start a constructive conversation about things like race, implicit bias and equity."For one, getting perspective and understanding a bias you might have because you can't do anything about it if you can't spot it," said Berman.So they came up with a 10 question, online survey that asks things like, "Do you believe hard work puts you on your path for a promotion?Do you have a close friend that is black?""We're not trying to nudge you one way or the other, we're just trying to say hey pick a side lets start talking and work this out," explained Nimry.At the end, you get to see how other people responded and access links to learn more, donate to civil rights organizations, even register to vote.The creators say the idea is to share what they learn and then take all that data and develop a sort of "seal of approval" for consumers to know how different companies stack up."Launching almost a diversity/inclusion certification for organizations," said Berman. "It's not about calling out companies. It's about let's put a solution in place that allows the next generation to do what they want to with their jobs."The survey is open to anyone and accessed here: http://www.itsblackandwhite.us 1467

  

SAN DIEGO - San Diego photographers are taking advantage of the serene and luminous glow of the surf this week.Eerie neon blue waves have been seen against San Diego's shore this week, creating some rare photo opportunities. The phenomenon is created when a red tide, which is algae bloom filled with phytoplankton called "dinoflagellates," rolls off waves onto or near the shoreline.The organisms react with a bioluminescent chemical reaction when jostled as a way to warn predators, to lure prey, or communicate within their species. The blue glow can be created by a simple step in the water or crash of a wave.IN SAN DIEGO...The current red tide is being caused by massive numbers of dinoflagellates including "Ceratium falcatiforme" and "Lingulodinium polyedra," according to the Scripps Institution of Oceanography at UC San Diego.The Scripps Institution of Oceanography at UC San Diego is not affiliated with The E.W. Scripps Co., the parent company of this station. Researchers do not know how long this current red tide will last or "the full spatial range of the bloom." In the past, blooms have lasted anywhere from a week to a month or more.San Diego's last red tide event in September 2013 lasted one week, while the previous one in October 2011 lasted a month, according to researchers. Previous ones have lasted even longer.Monday's event was captured from La Jolla to Encinitas. Scripps recommends viewing the marine event from a dark beach at least two hours after sunset, though visibility is not guaranteed.IS IT HARMFUL?...In some areas, a red tide can be toxic to local marine life. In California, the majority are not caused by species that produce toxins, such as domoic acid, according to researchers. However, it's still best to be cautious around the bloom.The Southern California Coastal Ocean Observing System at Scripps samples the water for potential harmful algal toxins weekly.Red tides are unpredictable events and do not always give off bioluminescence, Scripps said.BUT WHY IS IT RED?...The red coloration is due to the high number of organisms in the water. During the day, organisms will swim to the surface to soak in sunlight. Each cell contains a little sunscreen that gives off the color, according to Scripps.When these organisms gather at the surface for sunlight, they can create an especially intense red.Researchers say a combination of physical, chemical, and biological factors are the driving forces behind allowing red tides to form. 2586
