The pilot, who managed to free himself, was the sole survivor.Liberty Helicopters describes itself as "the largest and most experienced helicopter sightseeing and charter service in New York City," with a fleet of 10 Airbus helicopters. But it hasn't said much about the latest crash, deferring to federal authorities.  600

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

WILMINGTON — President-elect Joe Biden has announced top White House staff positions Tuesday, drawing from the senior ranks of his campaign and some of his closest confidants. Biden confirmed that former campaign manager Jen O’Malley Dillon will serve as a deputy chief of staff. Campaign co-chair Louisiana Rep. Cedric Richmond and campaign adviser Steve Ricchetti will also play senior roles in the new administration. Richmond will leave his Louisiana congressional seat to fill the White House job. A former chair of the Congressional Black Caucus, Richmond was among Biden’s earliest high-profile supporters and served as his campaign co-chair.Anthony Bernal, who was Chief of Staff to Dr. Jill Biden on the campaign trail was named her Senior Advisor. Dr. Biden's Chief of Staff will be Julissa Reynoso Pantaleon. Other hires announced Tuesday include: Mike Donilon as the new Senior Advisor to the President, Dana Remus as Counsel to the President, Julie Rodriguez as Director of the White House Office of Intergovernmental Affairs, and Annie Tomasini as Director of Oval Office Operations. The new hires represent an initial wave of what will ultimately be hundreds of new White House aides hired in the coming weeks. The latest round reflects his pledge to have diversity in his staff — the team includes four people of color and five women. 1358

With home-court advantage taken out of the equation this year because of COVID-19, the NBA playoffs look nothing like they once did. And on Wednesday, the season took yet another dramatic turn with at least one team boycotting the championships.The Milwaukee Bucks boycotted their game to protest the shooting of Jacob Blake in Kenosha, Wisconsin. It raises the question: what does this mean for the current moment of racial reckoning the nation has found itself in?Dwight Lewis, an activist during the civil rights movement, says it's about more than one game or any sport in particular."Sometimes you have to do things to get attention and say, ‘I can’t take this anymore. I’m mad as hell and I’m not going to take it anymore,’" the now 72-year-old activist explained.For athletes and teams in the national spotlight, it's about using their platform to get the country to pay attention."If you don’t speak out now, what are people going to say about you? That’s what was great about what the Bucks did," he added.Professional athletes using their platforms to protest racial inequality is nothing new. The first time it happened was during the 1968 Olympics when two African American runners raised their fists during the national anthem to call attention to the civil rights campaign.Lewis says decades later professional athletes are still harnessing the power that comes with their position to help enact change and move the national dialogue on race forward."This is 2020. We’re no better. Racism is still as American as apple pie, unfortunately. So, what did we do to keep these people from not wanting to walk off the basketball court or the football field? What did we do?" 1690

When students normally head back to school, they're greeted with new teachers, classmates, and a new school picture. But professional school photos are either delayed or looking a little different this year because of the pandemic."It's very different. One of the things is we had a lot of schools that hadn't even started back yet, but a lot that have come back have pushed back their start date," explained Erin Middleton, the manager of operations for BPI Photography in Georgia.Middleton says their company is working closely with schools to safely photograph students who are back in-person in the classroom and accommodate those who aren't. BPI Photography says it first works with schools--with social distancing and masks in mind--to take photos of students who are at the school."Then, we actually create a report that is a not-photographed report, and on that not-photographed report would be your students that are face-to-face that didn’t make it on the original picture day,” Middleton explained. “But we also are capturing our virtual students on the absentee day which is like a make-up or retake day.”Middeton says sometimes the photos for virtual students take place after school hours. The company says they are doing everything they can to accommodate schools and families during this unprecedented time. A time some people are wanting to remember in their school picture. That means students and faculty taking their pictures while wearing a mask.For families who are feeling a little lost at this time, Shutterfly and Lifetouch are offering a 2020 School Picture Day guide on their website, plus a new feature for students who are remote learning from home."What we wanted to do in this crazy year of COVID is be able to provide some options for parents and we are photographing at lots of schools around the US but also where picture day isn’t taking place,” said Stephanie Schmid, vice president of marketing and merchandising for Lifetouch. “We wanted to provide a really flexible option for families and meet them where they are, and oftentimes, that's in their living room or their kitchen."Lifetouch launched a new feature through Shutterfly's app, where parents can upload a photo of their child and choose a professional background that they'd normally see in school photos. This allows them to order a school photo that looks just like the one they'd have taken at school."We know families like to have a collection, so you have that child and you want that kindergarten through 8th grade collection and sometimes families order the same background every year. What we did is we offered blue, which is the iconic Lifetouch Picture Day background along with a number of other best sellers so that families can continue their collection and not miss a beat even with a year like this, with COVID-19," said Schmid.Capturing the smiles on children's faces, even if they've had a rocky start to the school year. 2944
