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 you’re going to a firework show for Fourth of July, there will be more than one reason to look up to the sky.A penumbral lunar eclipse will occur during the evening hours on Saturday, which will be visible throughout the continental United States.A penumbral eclipse means that some, but not all, of the moon will be partially in Earth’s shadow. Despite the lunar eclipse occurring during a full moon, the moon will appear to be slightly darker during the peak of the eclipse. At its peak, more than one-third of the moon will be in parts of Earth’s shadow.Saturday's eclipse differs from total and partial lunar eclipses as the Earth will not completely block the sun’s light from reaching the moon.The next total lunar eclipse visible from America will not occur until 2022. 787

In an election year in the middle of a global coronavirus pandemic, a new study finds the majority of Americans, about 80 percent, are confident in-person polling places will be run safely.Survey respondents also seem to agree that it is important for Americans to learn who won the election within a day or two of Election Day, about 82 percent, but only about 50 percent feel confident this will actually happen.Other questions asked on a recent Pew Research Center study appear to have strong partisan divisions.When it comes to being confident about in-person versus mail-in ballots being counted, overall 90 percent of respondents feel good about in-person ballots being counted as voters intended.The confidence in mail-in ballots being counted as voters intended differs; just 37 percent of those who support President Donald Trump say they are confident in mail-in ballots, compared to 77 percent of those who support Democratic presidential nominee Joe Biden.These feelings lead to a 30-point difference in which supporters are planning to cast their ballot in person on Election Day; 50 percent of Trump supporters say they will vote in-person, while just 20 percent of Biden supporters say they will.Roughly 20 percent of both Trump supporters and Biden supporters reported they had already voted or planned to vote in-person during their state’s early voting.The sides also differ on their feelings about how Election Day will be administered around the country. About 90 percent of all survey participants have confidence in their local community elections to be run well.However, 72 percent of Biden supporters feel confident about elections around the country and just 50 percent of Trump supporters feel confident about elections being run well around the country.The survey was conducted the first week of October, talking to more than 11,900 American adults. 1884
