SAN DIEGO (KGTV) - Vandals damaged a park in Sabre Springs Thursday night, dumping sand into toilets and scrawling inappropriate graffiti on the walls. Trash cans were emptied out and piles of wood chips were dumped along the entrance to the South Creek Neighborhood Park. The clogged toilets and sinks caused minor flooding in the bathrooms. Some of the plumbing was also damaged, according to the San Diego Police Department. City crews cleaned up the mess by the afternoon. Police were still searching for the culprits Friday. 537

SAN DIEGO (KGTV) — Two greater one-horned rhino calves took their first steps into their habitat for the first time this week at the San Diego Zoo Safari Park.Next to their mothers Asha and Tanaya, the calves — born on March 25 and April 11, respectively — were finally able to explore their Asian Savanna habitat. Both pairs bonded while traversing the area, before intereacting with some of the other wildlife in the habitat.Tanaya and her female calf, which has not yet been named, enjoyed some wallowing in the mud, taking a cool dip, and meeting some of the blackbuck antelope and other animals in the 40-acre habitat.Asha and her male calf, named Arjun, explored hills and grassy areas. Arjun also met one of the habitat's Javan bantang (before quickly running back to mom's side."It’s great to see Asha and Tanaya introducing their calves to other wildlife for the first time," said Jillian King, senior wildlife care specialist, San Diego Zoo Safari Park. "Everything is new to the calves right now, so it will be interesting to watch them explore. We will keep a watchful eye on them, and look forward to them meeting more of the wildlife on the savanna soon."The greater one-horned rhino is listed as "vulnerable" on the International Union for Conservation of Nature Red List of Threatened Species. This is primarily because of habitat loss, poaching, and illegal rhino horn trafficking.The species, once widespread in Southeast Asia, is now only found in India and Nepal. There are an estimate 3,500 greater one-horned rhino left in the world. 1563

SAN DIEGO (KGTV) -- We’ve known for a while that COVID-19 hits people over 65 especially hard, but a study published Wednesday from researchers in San Diego offers new insight into why that happens.The numbers are staggering: if you’re 65 or older, your risk of winding up in the hospital from COVID-19 is five to 11 times higher than someone under 30. Your risk of death is at least 90 times higher, according to data from the Centers for Disease Control and Prevention.Researchers at the La Jolla Institute for Immunology say the reason why older people fare so much worse appears to be from a lack of T-cells, a type of white blood cell that can decline with age.“Some viruses get controlled by one part of the immune system. Some viruses get controlled by another. In this case it seems that T-cells really do a lot of the work,” said Dr. Shane Crotty, one of the authors of the study published Wednesday in the journal Cell.Dr. Crotty and his colleagues looked at 50 people infected with the virus, and they measured the three elements of the adaptive immune system in detail: antibodies, helper T-cells and killer T-cells.Then they compared the measurements to how people fared against the virus. Some patients in the study group had severe cases, others had mild infections.The researchers found that people with all three branches of the adaptive immune system tended to fully recover. People with severe cases of the virus often lacked one or more of the immune branches, and it was particularly evident in older people.“Our data indicated that of the older individuals, it was particularly the ones that had fewer T-cells to start that look like they really struggled to control this virus,” Dr. Crotty said.As we age, we have fewer T-cells to send after invading pathogens. “That collection of T-cells gets smaller. So it’s harder to recognize a new virus,” Crotty said.Among the 748 deaths in San Diego County reported as of Wednesday, 87% were people aged 60 and older.The findings from LJI may have implications in the search for a vaccine against COVID-19. The data suggests that vaccine-makers may want to target a drug that elicits all three branches of the immune response, Dr. Crotty said. Some vaccine approaches, such as inactivated virus vaccines, only elicit two of three branches, not killer T-cells. However, Crotty said it was too soon to rule any candidates. Two strong branches produced by a vaccine could potentially cover for the lack of a third, he said.Crotty said the findings could help vaccine-makers interpret results from the clinical trials and find the right dosing.“Is a given vaccine a good vaccine, and you just need a booster immunization?” he said. “Does it work well in one population but it doesn’t help in the elderly because it doesn’t generate a T-cell response, for example? Those are the scenarios when this type of knowledge will come into play.” 2906

SAN DIEGO (KGTV) -- When entering most newly reopened businesses in San Diego County, customers will need to sign in with their name and phone number.The change only applies to businesses now offering indoor services; the county’s public health order was updated to reflect the changes now in effect for the following sectors:Hair Salons & BarbershopsPersonal Care ServicesGyms & Fitness CentersRestaurants, Wineries, Bars, Breweries, and Distilleries that serve food.“It’s a very modest step that can aide in our close contact investigation, and I think can help slow the spread and help these businesses stay open,” said County Supervisor Nathan Fletcher.Many people already give their name and phone number when making a reservation at a restaurant or booking a hair appointment; this won’t look much different, just more widespread, and businesses will also keep the sign-in sheets for three weeks.“In the event, there is an outbreak or exposure, I think most people would want to know if they’ve been exposed so they can quarantine or potentially get tested,” said Fletcher.If a COVID-19 outbreak happens, customers who visited will be notified if they were possibly exposed. The county will not collect or save the information.“It would only be used in the event there was a public health risk,” said Fletcher.Fletcher said the new plan could have possibly helped with contact tracing during the last wave or reopenings.“It’s certainly something we could have been done before, maybe a lesson learned from earlier, I think this could really aide in helping more quickly in letting folks know if they’ve been exposed," Fletcher said.Some people may have privacy concerns and be reluctant to give their personal information.Cybersecurity expert Ted Harrington, who is an executive partner at Independent Security Evaluators, says that while giving an email address would feel less invasive, the risk of providing a phone number and name is still minimal.“There’s no doubt what this order is doing is giving more information for people who don’t yet have a process to safely protect it, so we should accept that is the reality of what’s happening,” said Harrington. “But, is that a strong enough reason to not go to a restaurant or get your haircut or whatever? I wouldn’t be any more concerned than you might normally be with giving your phone number to a restaurant when you leave a reservation.” 2417
