DEL MAR (KGTV) — For the first time, researchers set up receivers along San Diego coast with the ability to record when sharks are near. California State University Long Beach spent Wednesday working with Del Mar lifeguards as they dropped three receivers along the coast and tried tagging sharks nearby. Unfortunately, no sharks were tagged.Chris Lowe, with Shark Lab, tells 10News, “we just got money from the state to expand it throughout all of California.” They have receivers from Avila to the Mexico border but none located between Oceanside and La Jolla."This is a big gap for us,” Lowe says.Each receiver collects data from any tagged shark within 500 yards of the device. The receiver logs the time, date and is able to identify the exact shark based on the scanned tag. For a decade, CSU Long Beach has been studying the patterns of sharks and working to collect enough data to eventually predict where sharks will be at certain times of the year. 967

David Rush loves breaking world records; as a matter of fact, he has over 150 entries in the Guinness Book of World Records.This week, Rush’s latest foray into the world records book was for most targets hit with a single-shot Nerf gun. In one minute, Rush hit the target 24 times, breaking his previous record of 19.Rush said that he previously set the record unofficially at 24, but it did not count as the video he used to document his attempt did not take.With the Nerf gun being “single-shot,” Rush is required to reload between each shot.Rush says he uses his record-breaking attempts to promote STEM education. Rush said he has an electrical engineering degree from MIT, an MBA from Boise State.Other records Rush has set include farthest distance trekked balancing a bike on chin, most t-shirts worn and torn in one minute, and most leaves raked in one minute.To watch Rush go for the Nerf gun world record, click here. 936

Data and images gathered by Harvard University research indicate that several hospitals in Wuhan Province, China, which was the early epicenter of the coronavirus, began seeing an increase in traffic as early as last August.The Harvard researchers stressed that the data cannot be conclusively linked to the spread of coronavirus. But the study’s authors said that the research supports its hypothesis that the virus originated before being identified last December.The researchers used satellite images from hospitals in addition to search engine data to back its study. The images showed an increase in hospital traffic while search engines showed an uptick in inquiries of coronavirus-related symptoms.The research noted that there are seasonal changes in online searches for “cough,” there was also a subsequent jump in searches for “diarrhea,” which the researchers said is a more coronavirus-specific search term. The authors said both search query terms show a large increase approximately 3 weeks preceding the large spike of confirmed COVID-19 cases.“Our retrospective analysis cannot verify if increased hospital and search engine volume is related to the SARS-CoV-2 virus,” the authors wrote. SARS-CoV-2 is the strain of the novel coronavirus. "While alternative explanations such as the 2019 Military World Games in Wuhan may explain some increases in parking lot traffic, this event opened on October 18, 2019, weeks after the initial rise in Baidu search engine traffic.“Still, further research is needed to validate the emergence of SARS-CoV-2. This study adds to a growing body of work on the value of digital sources as an early indicator of a disease outbreak in the context of limited integrated electronic surveillance data.”To read the full study, click here. 1788
