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

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

When Nolan Davis called his community to march for Black Lives Matter, hundreds turned up for the cause. On Saturday, he led demonstrators from a park in his hometown of Kirkwood, Missouri to the town's city center, leading chants along the way.But Nolan's protest looked a bit different than others that have taken place across the country in recent weeks — because almost all the participants were children.Nolan, 8, helped organize the protest along with his mother, Kristin Davis. According to CNN, he was inspired to lead his own protest after the two attended a few other rallies in the St. Louis area.Nolan and his mother designed a flyer to get the word out about the protest and shared it on Facebook. Nolan told CNN that he believed that about 50 people would show up to his event. But when he arrived at the park on Saturday morning, there were about 700 people ready to support his movement.According to CNN, Kristin Davis, who is white, adopted Nolan and his 5-year-old sister, Caroline, who are both Black. Their mother says that while she could never understand what her children go through, she's tried to have regular conversations about racism with them to keep them safe."We're preparing them for when they're older and taller and bigger. When they're not going to be perceived as cute little kids anymore," Kristin Davis told CNN.During the protest, Nolan held a sign that read "Kids Can Make a Change," according to photos from St. Louis-Post Dispatch. 1481

With news of two highly effective COVID-19 vaccines on the horizon, health officials and scientists are giving us new insight into how we could gain herd immunity."If we think of the population as a single group of people with all similar risks and susceptibilities and behaviors, we need 60% of people to be immune, meaning that not only they don’t get sick, but also they don't pass on the virus to other people," says Dr. Stuart Ray, an infectious disease professor and herd immunity expert at Johns Hopkins University.Dr. Ray says achieving herd immunity with the help of a COVID-19 vaccine would mean enough people would either get the vaccine or already have recovered from the virus and be immune to help stop the spread of the virus."It's a little bit like this notion that if you’re going to pass on a message from a lot of people in a group, they have to speak the same language. And the more people don't speak the language, the harder it's going to be to pass that message and there’s a threshold at which the message just gets stopped," says Dr. Ray.Still, it would take a certain number of people to get the vaccine and have that immunity last in order to reach herd immunity. Stanford University's Dr. Bali Pulendran hopes that we can achieve herd immunity, even though there are a certain number of people who are still hesitant to take the vaccine."I think we should remember that a vaccine that is 95% effective is only effective if the majority of people in a population take it. If only half the population or only 60% of the population take it, then we are unlikely to have achieved the level of herd immunity that you need for curbing the disease," says Dr. Pulendran.And if the new COVID-19 vaccine requires two doses, how crucial will it be to make sure people receive that second round of immunization?Asked whether follow up will be a concern, Dr. Ray says, "I think it is a possible concern. We’re going to do a lot of learning. So, one of the things we’ve learned is that some vaccines we thought you needed multiple doses, one dose works pretty well."Doctors say research will be ongoing on the vaccine and the virus itself to ensure people will be protected as much as possible, because so many are hopeful for an end to COVID-19. 2268

What’s the difference between a place with patchy shrubs and a lush, wooded forest on Google Maps? In the past, the answer was nothing, they were both the same color of green. Now, Google Maps will be using a wider color spectrum to bring out more details.Using high-definition satellite images from more than 98 percent of the world’s populated areas, Google uses a new color-mapping “algorithmic technique” to translate the information into a more vibrant map.The idea, according to a blog post from the company, is to create a map with more natural features, so users can quickly distinguish between tan beaches and deserts, or blue lakes, rivers, oceans and ravines.The team at Google Maps explains how the color-mapping works. “First, we use computer vision to identify natural features from our satellite imagery, looking specifically at arid, icy, forested, and mountainous regions. We then analyze these features and assign them a range of colors on the HSV color model.”Google Maps has undergone a handful of updates this year in conjunction with the app’s 15th year in existence, including a better sense of depth in Live View, more detailed directions for commuting, and easy-to-find contribute and explore tabs.Still to come, Google Maps is promising an update that will show more details about street width and shape. Allowing users to see exactly where sidewalks, crosswalks and pedestrian islands are. 1424
