Hurricane Laura is expected to create an “unsurvivable storm surge,” of up to 15 feet in some places, according to the National Hurricane Center.Here is an explanation of what storm surge is, and why it can be so deadly.“Storm surge is the rise in seawater level caused solely by a storm,” says NOAA. It is measured as the height of the water above the “normal predicted astronomical tide,” caused by the storm’s winds pushing water onshore.A “storm tide” is the total observed water level during a storm that includes storm surge and astronomical tide. Astronomical tides are caused by the gravitational pull of the sun and moon.According to NOAA, the National Oceanic and Atmospheric Administration, the highest storm tides are often observed during storms that coincide with a new or full moon. 805

In a victory for employers and the Trump administration, the Supreme Court on Monday said that employers could block employees from banding together as a class to fight legal disputes in employment arbitration agreements.Justice Neil Gorsuch delivered the opinion for the 5-4 majority, his first major opinion since joining the court last spring and a demonstration of how the Senate Republicans' move to keep liberal nominee Merrick Garland from being confirmed in 2016 has helped cement a conservative court."This is the Justice Gorsuch that I think most everyone expected," said Steve Vladeck, CNN contributor and professor of law at the University of Texas School of Law. "Not only is he endorsing the conservative justices' controversial approach to arbitration clauses, but he's taking it an important step further by extending that reasoning to employment agreements, as well."Justice Ruth Bader Ginsburg took the rare step of reading her dissent from the bench, calling the majority opinion in Epic Systems Corp. v. Lewis "egregiously wrong.""The court today holds enforceable these arm-twisted, take-it-or-leave-it contracts -- including the provisions requiring employees to litigate wage and hours claims only one-by-one. Federal labor law does not countenance such isolation of employees," she said.In the majority opinion, Gorsuch maintained the "decision does nothing to override" what Congress has done."Congress has instructed that arbitration agreements like those before us must be enforced as written," he said.As the dissent recognizes, the legislative policy embodied in the (National Labor Relations Act) is aimed at 'safeguard[ing], first and foremost, workers' rights to join unions and to engage in collective bargaining," he wrote. "Those rights stand every bit as strong today as they did yesterday."Gorusch, responding to Ginsburg's claim that the court's decision would resurrect so-called "yellow dog" contracts which barred an employee from joining a union, said that "like most apocalyptic warnings, this one proves a false alarm."The case was the biggest business case of the term, and represented a clash between employers who prefer to handle disputes through arbitration against employees who want to be able to band together to bring their challenges and not be required to sign class action bans.It also pitted two federal laws against each other.One, the National Labor Relations Act (NLRA), gives employees the right to self organization to "engage in concerted activities for the purpose of mutual aid or protection" the other, the 1925 Federal Arbitration Act (FAA) allows employers to "settle by arbitration."Lawyers for employers, who have long backed arbitration as a means of resolving disputes, argued that class action waivers are permissible under the 1925 law. They say the NLRA does not contain a congressional command precluding enforcement of the waivers.The Trump administration supported the employers in the case, a switch from the Obama administration's position.  3034

In a new study of mask usage published by the American Institute of Physics, researchers found that if 70% of people wore surgical masks, the pandemic would be "eradicated."According to the article, which was published Tuesday, investigators with the Department of Engineering at the National University of Singapore looked at studies that reviewed N95s, surgical masks, and cloth masks to see how the mask's design, material, and capability of protecting people from the virus, was.Authors Sanjay Kumar and Heow Pueh Lee found that if 70% of people wore surgical masks in public consistently, the pandemic could be eradicated. Even cloth masks, which they found to be 30% effective, could lead to a "significant reduction of COVID-19 burden."The researchers analyzed that if masks are worn, it reduces the size of fluid droplets expelled from the nose and mouth, spreading the virus in the air. The investigators said small droplets traveled a more considerable distance and were in the air longer because they became aerosolized.According to the article, the researchers found that the N95s filtered out aerosol-sized droplets, and masks made with hybrid polymer materials effectively filter particles while simultaneously cooling the face. 1250

If you use Alexa, listen to this. Instead of just playing your music or answering questions, it could soon tell if you're getting sick and suggest you buy things like cough drops or soup!It’s just one of the ways health marketers are using technology to reach consumers.A new thermometer app allows user to track fevers and symptoms. This flu season, Clorox paid to get that information and used it to target its ads to zip codes that had increases in fevers.Daren Duber-Smith, a marketing processor at MSU Denver, says this marketing technique isn’t new. Companies like Google and Facebook are already sharing user information.However, sharing health information is something new.“I don't think when people are buying thermometers that they necessarily really know that these devices can not only collect a lot of data about them, but that they're under current regulations they're allowed to share that data,” Duber-Smith explains.  Kinsa, the company that makes the smart thermometer, says this so called "illness data" doesn't have any identifying personal data when shared with other companies. But Kinsa’s thermometer, as well as Amazon’s new patent that could enable Alexa to detect cold symptoms, are just two of many technologies raising questions about privacy.“I think when it comes to personal health, people might be willing to give up a little bit more privacy if they perceive that it's going to help them live longer and help them live healthier lives, or maybe save their lives in some instances,” Duber-Smith says.Still, Duber-Smith believes how much is disclosed should be up to the consumer.  1640

HUNTINGTON BEACH, Calif. (AP) — Wildlife officials say a goose is recovering after being found with a large arrow through its neck at the same Southern California park where a goose and a gull swallowed prescription pills last month.The Los Angeles Times reported Monday that the goose flew around with the arrow in its neck for a week before it was finally captured at Carr Park in Huntington Beach.The arrow was removed and the bird was given antibiotics, IV fluids and painkillers. It's expected to fully recover.Shortly before Christmas, a Canadian goose and a ring-bill gull had their systems flushed after eating pills — including sedatives — that someone dumped in the park. Both birds have recovered after being treated at a wildlife center.Officials don't know whether the two incidents are related. 816
