SAN DIEGO (KGTV) - Imagine having the power to change your body’s temperature at any time, regardless of how hot or cold it actually is. UC San Diego engineers are on they’re way to doing just that, with a wearable patch.Like a thermostat, it can be changed to a specific temperature, warming or cooling the body, using far less energy than an air conditioning system. “Cooling is a really important issue faced by society today. If you look at news reports there are extreme weather conditions, for example in India, peak temperature could be over 50 degrees Celsius in July," said Renkun Chen, a Professor of Mechanical and Aerospace Engineering at UC San Diego.The patch is made up of thermoelectric alloys - materials that use electricity to create a temperature difference and vice versa - sandwiched between stretchy elastomer sheets. The device physically cools or heats the skin to a temperature that the wearer chooses. The patch is powered by a flexible battery pack. It is made of an array of coin cells all connected by spring-shaped copper wires and embedded in a stretchable material. The system also includes a stretchable circuit board.By regulating the temperature around an individual person, rather than a large room, the smart fabric could potentially cut the energy use of buildings and homes by at least 15 percent.The technology could also be used for people who work in extreme environments, like firefighters or miners. Eventually, Chen and his team want to integrate the technology into clothing. They hope to sell it commercially in the next few years, along with developing a mobile app to control the temperature. The research was funded with a .6 million grant from the U.S. Department of Energy. 1736

SAN DIEGO (KGTV) — In 2004, San Diego taxpayers approved a transportation tax increase that earmarked 0 million for bike projects for more bike lanes, safety features on the roads for cyclists and foot traffic, and new walking trails.Friday, SANDAG said it's going to need more. Officials said rising construction costs have called for an additional million for the projects, many of which have been started.The money would come from funds already allocated for these types of projects.RELATED: Compromise proposed for 30th Street bike lanes in North ParkCritics of the increase in funding argue only one percent of San Diegans use bikes and costs of .5 million per mile built for these bike lanes is unjustified.The San Diego Bike Coalition says the funding is needed to provide San Diegans with more transportation options, reduce auto dependency, and increase safety of bicyclists. They add that an expanded bike network will help the county move closer toward greenhouse emissions goals.SANDAG has been working toward the biking goals since 2013, when the agency approved a 0 million Bike Early Action Plan. The plan, funded by the region's half-cent tax on public transit fares, includes 40 projects totaling 77 new miles of bikeways and paths around the county.Crews broke ground on the first phase of the project last December and expects to complete two projects by early 2022. 1405

SAN DIEGO (KGTV) – It's exploding in the wellness industry, but is CBD safe? 10News visited a San Diego lab that tested CBD products for ingredients like pesticides and heavy metals. The results were surprising to lab personnel. Shelby Huffaker is the lead cannabis educator at Torrey Holistics in Sorrento Valley. The licensed dispensary recently conducted its own CBD study to show customers just how unreliable the open market can be. "We collected about a dozen different products from various locations around San Diego and also on the internet," she tells 10News. Torrey Holistics collected samples from places like farmers' markets, grocery stores, and the internet. The company bought CBD products such as lip balms, caramels, creams, and bath bombs, then sent to San Diego's Infinite Chemical Analysis Labs. "It's pretty busy right now with it being harvest time," says David Marelius, Ph.D. He's the co-founder of Infinite Chemical Analysis Labs, which tests cannabis and related products. "People are definitely trying to take advantage of the CBD boom right now," he adds. Both CBD and THC come from the cannabis plant, but CBD does not have the psychoactive properties that give you the feeling of being high. CBD received praised for claims of health benefits like reducing anxiety and inflammation. According to Infinite Chemical Analysis Labs, none of the CBD samples purchased on the internet by Torrey Holistics had any CBD in them. Dr. Marelius tells 10News that the majority of the overall samples didn't meet their packaging claims. He adds that the products' potencies were off, and one product had almost 70% less CBD in it than what it advertised. Three of the products reportedly failed for pesticides, although the levels were so low that they likely weren't harmful. "It's kind of the wild west out there," says Sally Greenberg with the National Consumers League. Greenberg tells 10News that CBD sellers often exaggerate the benefits of CBD without having the science to back up the claims. "[They say] that they cure cancer or treat Alzheimer's or treat AIDS," she adds. The National Consumers League is advocating for federal oversight from the Food and Drug Administration, which currently doesn't regulate most CBD. In California, the Bureau of Cannabis Control tests CBD that's sold in licensed dispensaries, like Torrey Holistics. "You're going to want to look for a Batch number or UID number. That ensures that we're able to match the testing results with that specific product," says Huffaker. The dispensary is hoping that the lab results will highlight the importance of researching your CBD before buying. "Everything carried in a licensed cannabis store is going to have to be verified [and] vetted by the dispensary [to be sure] it has gone through the necessary testing," adds Huffaker. The state's Bureau of Cannabis Control has a search function on its website where you can see what licensed dispensaries are in your area, or you can search a dispensary to be sure its licensed.

SAN DIEGO (KGTV) -- It’s no mistake, the Marriott Marquis in Downtown San Diego is playing host to bees on the roof, and it’s all for the benefit of local business. The hive highlights a growing trend called urban beekeeping and the popularity of the practice is creating a lot of buzz. In 2012, the City of San Diego amended its municipal code to allow some residents, along with community gardens and retail farms to keep two beehives. The practice has several benefits, according to the city, including access to fresh, natural honey. The city says urban beekeeping also reduces the number of aggressive Africanized bees in the vicinity of the docile honeybee hive. Beekeeping is also known to reduce carbon footprint due to local production, however, there are some things to be aware of. The primary risk of beekeeping is getting stung. The city says if you plan to keep bees, you can count on bee stings every now and then. Before deciding to keep bees, the City of San Diego urges dialogue with neighbors.

Tomorrow morning on 10News at 6, Jared Aarons looks into what benefits the bees have downtown as well as some unique concoctions local restaurants are whipping up with the fresh honey. 1254
