Meanwhile, troubled coastal cities around the world are taking note, says Bren Haase, head of planning for the Coastal Protection and Restoration Authority. With a playbook in place, Louisiana already boasts a 50-year, $50 billion plan to rebuild the state’s coasts, one that’s grounded in decades of data and science; it’s also being translated into several languages, including Vietnamese, Spanish and French, for other countries to reference. Flush with billions of dollars from the settlement in the catastrophic BP oil spill, the Coastal Master Plan could hold key clues for other places facing a similar fate in the future, says Haase, including flood-risk areas like New York, London, Singapore and Kiribati. Moreover, Louisiana’s coastal restoration sector is fueling high-tech projects like artificial oyster reef creation, advanced hydrologic modeling and geosynthetics, which will help shore up the state’s defenses against behemoth hurricanes and oil spills.
Bill Fulkerson on 26 May 20Antigen tests don't amplify their protein signal, so they are inherently less sensitive. To make matters worse, that signal gets diluted when samples are mixed with the liquid needed to enable the material to flow across test strips. As a result, most antigen tests have a sensitivity of anywhere between 50% and 90%-in other words, one in two infected people might incorrectly be told they don't have the virus. Last month, Spanish health authorities returned thousands of SARS-CoV-2 antigen tests to the Chinese firm Shengzhen Bioeasy Biotechnology after finding the tests correctly identified infected people only 30% of the time, according to a report by the Spanish newspaper El Pais.
