I thought it was going to be a wonderful day. My high school, Marjory Stoneman Douglas, was full of cheerful students -- many of whom were celebrating Valentine's Day with one another. Even those who didn't have a Valentine seemed like they could find reasons to smile.  283

In a few weeks, thousands of college students will begin their yearly right of fall by returning to the campus of Tufts University in Medford, Massachusetts, but a return to campus life this year will mean testing and quarantining for those students who chose to come back.Like colleges and universities across the country, Tufts is experimenting with a new plan that will allow more than 5,000 students to come back to campus while at the same time, instituting rigorous new guidelines in an effort to keep COVID-19 from spreading.The key to success, testing.“We wanted to test for COVID at a frequency that would catch people when they’re asymptomatic before they have a chance to spread,” explained Tuft’s President Anthony Monaco.Tufts plan for the fall is as complex as the virus itself. Students from outside the Northeast will be brought back to campus first, where they will be forced to quarantine for 14 days. Health officials expect at least a small portion of those students to test positive for COVID-19 the moment they step back on campus. Because of that, the university has constructed an extra 200 modular units of dorm space. The idea of the modular facilities is to give campus health officials a contained area to monitor students who test positive for the virus, while at the same time, keeping them out of the general population.After students from outside the Northeast are brought back to campus, students from the general area around New England will return.Every single student will be tested twice a week for COVID-19, something experts say will be a key component to safely reopening college campuses this fall. Regardless, school officials expect students to test positive for the virus throughout the fall.Researchers at Yale’s School of Public Health have been advising Tufts and hundreds of other colleges who are planning to resume some form of in-person learning this fall.“If we don’t test frequently, we give silent spreaders an opportunity to grab hold and this virus is hard to play catch-up with,” explained Professor A. David Paltiel, who recently published a study on how quickly the virus can spread through colleges if left unchecked.To study the virus, Paltiel and his colleagues used epidemic modeling to assemble hypothetical situations resembling a college campus. The study found that if you take 5,000 healthy students and add in only 10 students who have COVID-19, hundreds, if not thousands, of kids will be sick by Thanksgiving.“At that point, the only thing that keeps the virus from getting out of control is Thanksgiving break,” he said.That is why testing is key, the study found. When Paltiel took those same 5,000 kids and added in 10 students who have COVID-10, but tested every student twice a week, the study found that only about 100 students ended up catching COVID.“Many universities are planning to only test students who have symptoms, in our view that is a recipe for disaster,” he said.Only adding to the uncertainty of the situation, about 40 percent of college students said they would return to live near campus even if classes were held virtually. Paltiel and other health officials say because of that, it’s more beneficial to have students on-campus where they can be monitored and tested frequently.“It’s hard and it could be a nightmare, people who say we shouldn’t open campuses should remember the nightmare doesn’t go away,” he said. 3420

If elected, Joe Biden said he would not build any additional miles of barriers between the United States and Mexico border, the former vice president told NPR earlier this week."I'm going to make sure that we have border protection, but it's going to be based on making sure that we use high-tech capacity to deal with it. And at the ports of entry — that's where all the bad stuff is happening," Biden told NPR.Biden added that he would no longer allow the federal government to confiscate land for the purpose of erecting a border wall, and that all lawsuits between landowners and the government would be dropped.While President Donald Trump has made border walls an important facet of his campaign and presidency, very little new wall has been added during his first three and a half year in office. As of a June update provided by Border Patrol, the agency has constructed three miles of new wall.Border Patrol said it replaced 213 miles of barriers in areas that were dilapidated. The agency said that 183 miles of barriers were in a pre-construction phase, according to Border Patrol.“Illegal drug and human smuggling activities have decreased in those areas where barriers are deployed. Illegal cross-border traffic has also shifted to areas with inferior, legacy barriers or no barriers at all,” said Acting CBP Commissioner Mark Morgan.In order to construct sections of border wall, Trump had to pull Congressional funding from military projects. The decision has caused legal wrangling on whether Trump has the authority to redirect funds earmarked by Congress. 1580

Hurricane Lane's outer bands have been pummeling Hawaii's Big Island with rain Thursday, triggering landslides and threatening serious flooding as the Category 4 cyclone moves perilously close to the Aloha State.The center of the storm — which could become the first major cyclone to make landfall in the state in 26 years — is expected to move very close to the main islands or cross land Thursday through Friday, forecasters said.It could be so devastating that authorities are urging residents to set aside two weeks' worth of food and water."Be prepared to shelter in place with 14 days of food supplies and water and any other necessities," Hawaii Gov. David Ige said at a news conference Wednesday.Track the stormThe storm's center, with maximum sustained winds near 130 mph, was in the Pacific about 210 miles south-southwest of the Big Island town of Kailua-Kona around 5 a.m. HT Thursday (11 a.m. ET).Landslides are a concern, with 10-30 inches of rain forecast through the weekend -- and slides already were happening on the Big Island as the storm's outer bands hit Thursday morning.On the Big Island's northern tip, landslides were blocking parts of Route 19, the county civil defense agency said.About 7 to 12 inches of rain already had fallen on parts of the Big Island by early Thursday, the National Weather Service office in Honolulu said.Buses around Honolulu have been picking up residents in need and taking them to shelters. All public schools canceled classes until further notice, and many state employees have been asked to stay home.Tropical storm force winds (39-73 mph) stretch out to 140 miles, so even if the hurricane doesn't make landfall, it could have widespread impact. Lane threatens to bring dangerous winds, landslides, rough surf and major flooding.All of the islands are under weather alerts.A hurricane warning is in effect for the Big Island as well as Maui County and Oahu -- meaning hurricane conditions are expected there. Kauai and Niihau are under a hurricane watch, meaning hurricane conditions are possible and that winds of at least 39 mph are anticipated in the comings days. 2133
