SAN MARCOS, Calif. (KGTV) - A possible school shooting threat made against San Marcos High School was deemed "unsubstantiated" by sheriff's officials, but there will be an increased law enforcement presence at the school on Tuesday. 240

Schools in the U.K. are removing analog clocks from exam rooms after students complained about not being able to read the time, according to The Telegraph.Malcom Trobe, deputy general secretary at the Association of School and College Leaders, says students are accustomed to using digital devices today."They are used to seeing a digital representation of time on their phone, on their computer," Trobe told The Telegraph. "Nearly everything they've got is digital so youngsters are just exposed to time being given digitally everywhere."Teachers are concerned about students stressing out during exams because they can't keep track of time. One educator said her high schoolers are only able to tell the time on devices with digital displays, which they can't use during exams, according to People.Many teachers turned to Twitter to share their experience and found that issues with analog clocks is a common trend. 935

Scratch and sniff stickers have gone high tech, becoming another way to test for coronavirus.Researchers at the University of Colorado and Yale University have developed a “u-Smell-it” test that works with an app.Essentially, users will use a high-tech scratch and sniff to detect whether they've lost their sense of smell.“There's five windows and they have different odors on each of them. Basically, all you have to do is take an app on your phone, and you basically scan the card. It has a QR code, and it recognizes the unique combination of odors. This is really important because you want the test to be different every time,” said Derek Toomre, professor at the Yale University School of Medicine.The user will choose the corresponding odors. And after, they're done. The app will give them a score on how well they did or didn't do.This test isn't meant to replace the PCR test or antibody tests that are approved by the FDA.“This would be a supplement. This would not be to replace. This would be a supplement so that, if you failed to smell, then you would know to go in for an antigen or PCR test, but you're more likely to be positive on those tests, so it would actually be really, really helpful. Think of it as a pretest.”Researchers behind the “u-Smell-it” test hope that it will help with the current testing shortage. Right now, they are seeking FDA approval for emergency use. If approved, they'll be making the tests at a larger scale. 1464

SAN YSIDRO, Calif. (KGTV) -- Migrants rushed the border Sunday morning, forcing the closure of the San Ysidro Port of Entry and several San Diego interstates. Southbound Interstate 5 and 805 closed at State Route 905, forcing drivers to be rerouted on one of the busiest travel days of the year. All north and southbound lanes of the port of entry were also closed to all vehicles and pedestrians, halting traffic. Las Americas Premium Outlets was also shut down due to safety and security. RELATED: Caravan marches toward US border in show of forceCheck out the map below for more:  626

Scientists at the University of Nevada, Reno School of Medicine (UNR Med), led by its Nevada State Public Health Laboratory (NSPHL) are studying a likely case of COVID-19 reinfection.Forty-eight days after testing positive for SARS-CoV-2 in April 2020 and after testing negative consecutively twice, a Washoe County, Nevada patient tested positive again, in June.The patient had tested negative on two separate occasions in the interim. The genomes of the patient’s virus samples were sequenced in April and June, displaying significant genetic discordance between the two cases, implying the patient was infected twice.“We examined the genomic material of the viruses and samples to investigate this, says NSPHL Director Mark Pandori. “It is just one finding, but it shows that a person can possibly become infected with SARS-CoV-2 a second time.”To solidify confidence in the case, Pandori and the research team partnered with the Washoe County Sheriff’s Office Biology Unit to conduct identity testing on the specimens and lab samples evaluated in the study to verify the specimens were from the same person.Embedded in the genomic material of SARS-CoV-2 is a detailed code that Pandori says may provide insight to a better understanding of this virus.“A virus has a biological genome like all living things. Since March, the NSPHL has analyzed the genomic RNA of approximately 200 positive COVID-19 samples from Nevadans who have tested positive for COVID-19,” said Pandori. “The power of genomic information could turn the tables in the fight against the coronavirus.” The information is shared to a world-wide database known as “GISAID”,” alongside the work of thousands of researchers.According to Pandori and the NSPHL-led research team, reinfection cases are a potential warning sign that it is possible to catch COVID-19 more than once, and with unpredictable severity.“If reinfection is possible on such a short timeline, there may be implications for the efficacy of vaccines developed to fight the disease. It may also have implications for herd immunity,” says Pandori. “It is important to note, that this is a singular finding. It does not provide any information to us with regard to the generalizability of this phenomenon.”Herd immunity depends on the theory that after natural infection, our immune systems will collectively protect us as a community from reinfection and further spread. There are currently many more unknowns than knowns about immune responses to COVID-19. “After one recover from COVID-19, we still do not know how much immunity is built up, how long it may last, or how well antibodies play a role in protection against reinfection,” says Pandori.”While research and scientific advancements continue to build, Pandori says the hard work of fighting this pandemic together will continue through the use of facial coverings, hand-washing, social distancing, as well as wide-scale testing, contact tracing, and isolation of new cases.“This is a novel disease. We still have a steep learning curve ahead and lots of work to do, especially as inconvenient truths arise,” says Pandori.The NSPHL team are publishing their COVID-19 reinfection findings. Their report is publicly accessible on the SSRN preprint server, at https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3681489. This story was first reported by KTNV in Las Vegas, Nevada. 3384
