Top health officials are considering “pooled testing” as a way to ramp up COVID-19 tests.Here's how it works:Instead of testing each sample individually, labs pool together a certain amount, like 10, in one tube with one test.If it's negative, you double check it, and then you're done.If there's a positive, you break it down either into smaller pools or individually for further testing.“So, there are advantages, mostly cost savings, that's the huge advantage of pooling, also the ability to go through a very large volume of specimens,” said Dr. Thomas Quinn, an infectious disease researcher at National Institute of Allergy and Infectious DiseasesQuinn worked in one of many labs that used the pooling technique during the HIV epidemic in the 1980s. He says the difference between then and now is the tests themselves.Pooling dilutes the samples. The HIV tests were very accurate, so that wasn't an issue, but with COVID-19, the tests aren't as reliable.The other problem is pooling takes more time in the lab, even with robotic equipment helping.“We need to get everyone tested and everyone wants to know what's the result of my test within 24 hours. That's very hard to do with pooling,” said Quinn.Quinn isn't recommending pooling for individual testing right now. He says it could be more useful in big surveys, when it's not an emergency. 1357

There’s a common anxiety dream that involves walking into a classroom to discover it’s the day of finals and you haven’t cracked a book all semester. Then there’s the waking dream a lot of Americans have — the one where you’re getting ready to retire but haven’t saved enough money to cover expenses if you stop working.Just six in 10 workers report having saved anything — anything — for retirement, according to the Employee Benefit Research Institute, so a lot of people today may be losing sleep over their future finances.Even those who are making a diligent effort to prepare for their golden years are falling short: Data from workplace plan administrator and fund giant Vanguard shows that just 18% of workers save the 10% or more of income that experts recommend squirreling away for retirement. More than a third are putting away less than 4%. (Unclear where your savings stand? A retirement calculator is a good place to start.)Suspect you’re behind? Here are 13 ways later-in-life savers can address anemic retirement portfolios before it’s too late. 1080

TIJUANA, Mexico (KGTV) -- Mexican authorities said a Chula Vista woman and her friend were gunned down at a family gathering in Tijuana. Investigators said the suspect is a Tijuana firefighter who shot at the two during a jealous rage.The victim was identified as 32-year-old Roxana Diaz."She was always smiling, she was kind of crazy," said Diaz' cousin Ivett Corral. "A happy lady."Tijuana investigators said Diaz went to visit a family friend, 39-year-old Carlos Roberto Trujillo, in Tijuana Aug. 15. They and another female friend met with several Tijuana firefighters at a get-together.Early the next morning, the three friends headed to Trujillo's home at Colonia Union. Police said the three firefighters ambushed the group, shooting at Trujillo and Diaz, and kidnapping the other woman.Trujillo died just outside his home. Diaz underwent surgery at Tijuana General Hospital but died Aug. 20 after she was transferred to UCSD Medical Center. "I start crying a lot because she was like a sister to me," Corral said. "She was more than a cousin. We grew up together."Police said after the firefighters kidnapped the woman, she screamed for help at a toll plaza on the way to Ensenada. Officers were alerted and arrested the firefighters.Mexican investigators said the alleged shooter, identified only as 27-year-old Ricardo N., is the boyfriend of the woman he and his co-workers kidnapped. They said he was jealous that she was socializing with her ex-boyfriend Trujillo and Diaz.Corral said Diaz was a long-time employee at Kentucky Fried Chicken on 3rd Street in Chula Vista. She worked hard to provide for her 16-year-old son.Trujillo's family said he worked at the Tijuana Town Hall. He leaves behind three children."We just want justice," Corral said. Trujillo's family told 10News the suspects are being held in Ensenada on suspicion of kidnapping but have not been charged with the murders of Trujillo and Diaz. The families of Diaz and Trujillo have established GoFundMe accounts. 2002

There have now been more than 2 million confirmed cases of the novel coronavirus in the United States, according to a database kept by Johns Hopkins University.The U.S. surpassed the milestone early Thursday morning. More than 112,000 people have died in connection with the virus in the United States — all of them coming since February.Across the country, many regions are seeing a gradual increase in cases as states ease lockdown restrictions. Earlier this week, 14 states reported 7-day highs associated in newly-reported cases. Some of those see increases have occurred in rural areas of the country.More than 7.25 million people worldwide have contracted the disease since it was first detected in China late last year. The U.S. continues to lead all countries in confirmed cases, followed by Brazil (about 740,000 cases), Russia (about 493,000 cases) and the United Kingdom (about 290,000 cases).The U.S.also leads all countries in deaths linked to the virus, followed by the U.K. (about 41,000), Brazil (about 38,000) and Italy (about 34,000).Health experts suspect that the true number of people who have been infected with the coronavirus is likely much higher. Many people often experience mild symptoms and never seek out a test. Some countries, like the U.S., were also limited by a lack of testing resources at the beginning of the outbreak.Though there is currently no cure or vaccine for the coronavirus, Dr. Anthony Fauci of the National Institute for Allergies and Infectious Diseases says he hopes the NIH will have a "couple hundred million" doses of a viable vaccine available by the end of the year. 1630
