SAN DIEGO (KGTV) - Warmth and sunshine return to San Diego this weekend to make weeks of steady storms a distant memory. Temperatures will reach the mid 70s at the coast by Saturday, according to Kalyna Astrinos in the 10News Pinpoint Weather Center. The weekend will see gradual warming, with temperatures climbing to the high 70s by Sunday. Check your 10News Pinpoint Weather ForecastIn the desert, sunny skies will make the colors of wildflower super bloom pop. Expect temperatures in the 80s in the Borrego Springs area, Kalyna says.

No cloud cover should interrupt your sunbathing, and no strong winds are in the forecast to blow sand onto your towel. Lifeguards are prepared for crowds. SDFD lifeguards began using seasonal or part-time staffing March 1, in addition to full-time teams, according to San Diego Fire-Rescue spokesperson Mónica Mu?oz.Beachgoers will find their chief concern is finding a parking spot - not the weather.RELATED: Parking rules for San Diego Beaches / Check water quality at your favorite beaches / Exploring San Diego: Fun ways to explore San Diego's beaches / 'Dr. Beach' names Coronado Beach among best in the U.S. / Report card grades San Diego beaches' water quality 1342

SAN DIEGO (KGTV) -- Uber Eats will begin testing a new service that will deliver food using drones in San Diego, the company announced Wednesday. Uber and San Diego were granted the winning bid by the Federal Aviation Administration last year to test the new delivery service, according to the company. Here’s how Uber says the system will work: After a restaurant loads the meal into the drone and the drone takes off, a system will notify a nearby Uber Eats delivery partner to meet the drone at a drop-off location. The orders will then be picked up and hand-delivered to customers. RELATED: Juniper & Ivy ranked among best restaurants in the US for a night outIn the future, Uber Elevate plans to enable the drones to land atop parked vehicles within its rides network near delivery locations before the food is picked up and hand-delivered. The company says the initial phase of testing in San Diego was done with McDonald’s, but that it will be expanded later this year to include more restaurants, including Juniper and Ivy. “We’ve been working closely with the FAA to ensure that we’re meeting requirements and prioritizing safety,” said Luke Fischer, Head of Flight Operations at Uber Elevate. “From there, our goal is to expand Uber Eats drone delivery so we can provide more options to more people at the tap of a button. We believe that Uber is uniquely positioned to take on this challenge as we’re able to leverage the Uber Eats network of restaurant partners and delivery partners as well as the aviation experience and technology of Uber Elevate.” 1571

SAN DIEGO (KGTV) - UC San Diego School of Medicine researchers believe they have discovered a way to reduce what they describe as health risks associated with red meat. A study published Monday in the journal Nature Microbiology considers whether bacterial enzymes could be used to clear from our tissues a carbohydrate created when humans eat red meat. The carbohydrate, known as Neu5Gc, builds up as we eat red meat, researchers say. They suggest our immune systems treat Neu5Gc as a foreign invader and generate antibodies against it, leading to chronic inflammation and other diseases. A team led by UC San Diego professor of pediatrics and bioengineering Karsten Zengler, Ph.D., believes bacterial enzymes could remove Neu5Gc from red meat before people eat it. “It’s our hope that this approach could be used as a sort of probiotic or prebiotic to help reduce inflammation and the risk of inflammatory diseases - without giving up steak,” said Zengler. The researchers bought steak and pork sausage from a grocery store and rubbed it with a lab-made bacterial enzyme. They found that “sure enough, most of the Neu5Gc came right off,” according to UC San Diego officials. Zengler and his team are working to optimize the enzyme to make sure it removes Neu5Gc and not similar carbohydrates. The group will also explore mass production possibilities and the potential for preventing inflammation and inflammatory diseases.The study was funded by the National Institutes of Health, National Science Foundation, UC San Diego Chancellor’s Research Excellence Scholarship, and Science Without Borders, officials said. 1624

SAN DIEGO (KGTV) — Two new studies published this week suggest people with blood type O have a lower likelihood of catching COVID-19 and developing severe illness than people with other blood types.Blood type is a characteristic we inherit from our parents and there are four major blood groups: A, B, AB and O.Danish researchers looked at nearly 500,000 people who tested positive for COVID-19 and found that people with type O were underrepresented.In a study published in the journal Blood Advances, the researchers found 38.4 percent of those infected had type O when that type actually makes up 41.7 percent of the population in that area.The researchers say the findings suggest people with type O are less likely to get infected in the first place.On the other hand, the team found that people with type A blood were overrepresented: 44.4 percent of those infected had type A compared to an expected value of 42.4 percent. The researchers suggest people with type A might be more at risk.Another study, also published in Blood Advances, looked at 95 critically ill patients in Canada. They found people with type O or type B blood tended to have a shorter stay in the intensive care unit, an average of nine days for those blood types compared to 13.5 days for people with type A or AB.They also reported that people with type O or type B were less likely to need a ventilator, with 61 percent of cases requiring mechanical ventilation compared to 84 percent for people with blood type A or AB.“Yes, there may be some of these associations. I don't think it's fully understood at this point,” said Dr. Christian Ramers of Family Health Centers of San Diego, who was not involved in the studies.The science on COVID-19 risk and blood type is mixed. These two new studies align closely with a previous study in China and another in Europe, but a third study in the U.S. found no significant link between severe COVID cases and blood type.At this point, doctors aren’t sure why blood type might affect outcomes with the disease, but there are several theories.“The immune system is an incredibly mysterious and complicated thing that we don't fully understand,” Ramers said. “Blood type sort of plays into that because people with different blood types actually have slightly different immune systems and immune responses.”Your blood type impacts the kind of antibodies you produce. That is why it is so important in blood transfusions to get the right blood type; blood from the wrong donor can trigger antibodies that attack those red blood cells.People with blood type O have two sets of antibodies, known as anti-A antibody and anti-B antibody. People with type A or B only have one or the other.Researchers in the Canadian study hypothesized that the anti-A antibody in particular may help control the coronavirus. People with blood type O and blood type B produce this kind of antibody. Individuals with type A or type AB do not.People with blood type O also have characteristics that make them less prone to issues with blood clotting, a major issue in severe cases of COVID-19.Experts say that if type O blood is protective against the virus, it’s not by a large amount.And this protective benefit doesn’t extend to all pathogens. Past studies have shown people with type O are more at risk from a type of bacteria that can cause ulcers and cholera. 3369
