What you flush down your toilet could be brought back up to detect COVID-19.“Anytime that we are talking about poop, it’s a subject that either brings laughter or disgust; maybe a combination of the two,” said John Putnam with Colorado Public Health and Environment. Putnam is helping lead a team to test human waste to determine molecule levels linked with the coronavirus.“This gives you early warning that there could be an upsurge or a lessening of the disease in the community,” he said.Putnam says a person that’s been exposed to COVID-19 will pass the virus through their feces and possibly even urine. The waste eventually flows into sewer systems, which scientists will now collect.“We can then take a sample at a wastewater plant and send it to a lab,” he said.Labs at places like Metropolitan State University of Denver.“One of the advantages of this approach is that everybody in the community makes a contribution to the sewage,” said Rebecca Ferrell, Ph.D., a biology professor at MSU Denver.She says that when people get infected with COVID-19, they often shed the virus for several days before showing symptoms. Adding that this specialized stool sampling can alert scientists that the virus is in a community before people start getting sick.“It can give you extra warning about what might be happening in the hospitals then days maybe even a week later when people get sick enough that they are going to make demands on health care that you need to anticipate,” Ferrell said.With the cost to collect this data much cheaper than other options, Ferrell says more scientists are now teaming up with more wastewater treatment plants across the country.“These are the kinds of techniques where a relatively small investment early on can help us to get those resources to the right place and we can keep the mortality low,” she said.Hoping to get ahead of the pandemic, testing number two is becoming the number one priority for some scientists. 1965

While political pundits pontificate about Tuesday’s election results, thousands of high school students around the country will have been hard at work forecasting their own.In a March Madness-style round-robin challenge, students pick states they think will go Democrat or Republican, filling out their own electoral map and entering it among thousands of others in the FANschool Challenge.“It’s something fun. It’s something different that the kids can kind of get a little competitive about,” said high school government and economics teacher Gerald Huesken. “[It’s] friendly academic competition.”Huesken helped start the challenge along with two other colleagues four years ago as the country was gearing up for the 2016 election between Donald Trump and Hillary Clinton. Several of his students correctly predicted the Trump victory despite polls reflecting a different outcome. Back then, he says, it was only something for his class to do as they take what they learn in their civics and apply it to real-life situations, but now, it has exploded into an online format used by hundreds, if not thousands, of teachers across the country, says Huesken.“Right now, we’re looking at the different data from NBC, ABC, stuff like that [to guide our knowledge],” said Huesken. “It’s saying it’s looking pretty good for Joe Biden, but we thought that going into 2016.”Students get to draft states in a fantasy football format. They then learn about what is important to their voters, research news articles and polls, and then predict what they think will happen in 2020 based on what they find, putting together their minds and entering the bracket in a nationwide challenge for prizes.“I have both Florida and Ohio going Republican this year and giving Trump some votes,” said Mason, a junior in Huesken’s class who did not want to use his last name. “I also have Michigan going to Biden, leading him to a pretty comfortable victory.”Mason says the challenge has taught him how different regions of the United States approach different issues and how voting patterns change among different demographics.“If you asked me in 20 words or less why do you teach this course, it’s really because I feel like high school students, whether or not they’re voters, look at our political system and our political institutions and feel like they have no agency,” said Chris Stewart, a social studies teacher at a high school in St. Paul, Minnesota. Stewart helped start the challenge alongside Huesken and used it to helped formulate his fantasy politics course that he only offers during election years as a way to make the electoral process more relatable to many students who are not able to engage in the political process because they are not old enough to vote. 2764

With coronavirus cases surging in Florida, President Donald Trump said Tuesday that he’s “flexible” on the size of the Republican National Convention in Jacksonville.The president spoke as a growing number of Senate Republicans said they’d skip the event, and even as the White House tried to tamp down nationwide concern about the virus’s spread.Asked in an interview Tuesday whether he’d want to limit the gathering if the state’s coronavirus cases continue to rise, Trump replied that the decision “really depends on the timing.”“We’re always looking at different things,” Trump said during an interview on Gray Television’s “Full Court Press with Greta Van Susteren.”“When we signed a few weeks ago, it looked good,” the president continued. “And now, all of a sudden, it’s spiking up a little bit. And that’s going to go down. It really depends on the timing. Look, we’re very flexible.”There were about 452 new reported cases per 100,000 people in Florida over the past two weeks, which ranks second to Arizona in the U.S. for new cases per capita.He spoke as Republican lawmakers increasingly expressed concern about the gathering. Republican Sens. Chuck Grassley of Iowa, 86, and Lamar Alexander of Tennessee, 80, were among those saying they would stay away from the event. The virus takes a high toll on older people.Grassley was explicit about the reason for skipping the convention for the first time in his 40 years in public office.“I’m not going to go, and I’m not going to go because of the virus situation,” he said on a conference call Monday with Iowa reporters.Alexander, who is retiring after this year, was more subtle.In a statement released by his office Tuesday, he acknowledged that choices must be made and that fewer people gathered for the event is desirable. Alexander did not mention Trump, the pandemic or the fact that health experts say the virus is more transmissible among people in close proximity for prolonged periods.“Sen. Alexander is an honorary chair of the Tennessee Trump campaign, but he will not be attending the convention because he believes the delegate spots should be reserved for those who have not had that privilege before as he has had,” the statement said.About a dozen states are reporting worrying spikes of cases. The White House is trying to tamp down the nationwide concern despite more than 2.9 million confirmed COVID-19 cases and more than 130,000 deaths.Trump has falsely declared that 99% of cases of COVID-19 are harmless, a claim that is not supported by science.Florida is one of the nation’s hardest-hit states, and hospitals are warning they’re in danger of being overwhelmed. Florida’s COVID-19 positive test rate is 18.7%, making it second only to Arizona among states where coronavirus infections are surging. According to public health experts, a rate of 10% or more indicates the virus is spreading in communities.The rate is a snapshot of current conditions, and measures like social distancing, wearing masks, avoiding crowded indoor locations and frequent hand-washing can bring it down.Florida reached a grim milestone over the weekend, with health officials reporting that more than 200,000 people have tested positive for the coronavirus since the start of the outbreak.The highest number of confirmed cases in one day came Saturday, when more than 11,400 cases were reported in the state. More than 3,700 people have died.The convention is scheduled to begin Aug. 24. Officials in Jacksonville, Florida, began requiring face masks in public a week ago.“If you want to have a convention, and I think we should have a convention, I think you should do whatever you can to make it as safe as possible, so that would be with face masks and social distancing,” Grassley said.Grassley said he plans to continue his tour of all of Iowa’s counties, visiting 29 counties during the current two-week break. He and his staff will wear masks, but he doesn’t plan on requiring it for Iowans who come to see him.“There’s no way a United States senator can force anybody in Iowa to wear a mask,” he said. “It’s going to be up to the individuals and I would say that there’s generally a rule that if you’re 6 feet apart, you don’t have to wear a mask, but I think doing both makes common sense and I’m going to encourage people to do both.”___Associated Press writers David Pitt in West Des Moines, Iowa, and Ricardo Alonso-Zaldivar in Washington contributed to this report.___Follow Kellman at http://www.twitter.com/APLaurieKellman 4509

WISCONSIN — An update on the expected re-entry of China's old Tiangong-1 space station has been announced.The space station was initially launched in September 2011. An official Chinese statement declared that Tiangong-1 terminated its data service on March 21, 2016. Since the Chinese government has lost control of the station, it's hard to predict where and when it will fall.The European Space Agency predicts the space station will fall back to Earth between March 30 and April 6, while research organization Aerospace predicts a re-entry on April 1, give or take 4 days.Aerospace says it is much easier to predict a re-entry time than a location. This explains the wide scope of possible re-entry zones, which both Aerospace and other organizations predict will be between 43 degrees North and 43 degrees South latitudes. 855
