When it comes to educating America's children, how much of a difference could million make? Could it send a second grader on a school trip to the museum, or provide updated equipment to a class of budding scientists?It can. In fact, it can do it 35,647 times.Ripple, a cryptocurrency and international payment company, has donated million in cryptocurrency to DonorsChoose.org, a donation platform that connects people to classroom needs across the country. With the money, Donors Choose was able to fulfill every single classroom project request on its site -- 35,647 requests in all, from 28,210 teachers at 16,561 public schools."It's fair to say there's never been a day that this many classroom dreams have come true," Donors Choose founder Charles Best told CNN.The Colbert bumpThe massive donation is the culmination, or grand finale, if you will, of the site's #BestSchoolDay project. Two years ago, Stephen Colbert, who is a member of the Donors Choose board of directors, announced he was going to pay for every school project request in his home state of South Carolina.His act of kindness set off a movement that became known as #BestSchoolDay."More than 50 actors, athletes and philanthropists were inspired to fund classrooms in their states," Best told CNN. "Together, those 50-plus people gave more than million, and to use, that represented the idea of a best school day."Best says the response has been overwhelming -- in a good way."An outpouring of joy would not be an overstatement," he said.The Ripple effectBest says when the organization connected with Ripple, the cryptocurrency management company was "inspired to think of the impact" of such a significant gift."At Ripple, we care about giving back to our community and we collectively value the importance of quality education in developing the next generation of leaders," Ripple's SVP of Marketing Monica Long said in a statement."DonorsChoose.org's track record speaks for itself — they are highly effective at improving the quality of education and the experience of teachers and students across America. We're proud to work with them to support classroom needs across the country."According to Ripple's company site, the donation will affect approximately 1 million public school students.Best says the "classroom projects" requested on the site represent specific missions or activities that teachers have for their students."It's a public schoolteacher requesting a classroom library. A field trip. A set of art supplies. A pair of microscopes. It's about requesting experiences or tools to provide a student learning experience," he said."We believe in the wisdom of the front lines," Best added. "Hardworking, passionate teachers know their students' needs better than anyone else in the school environment. If we can tap into their needs, we can unleash smarter solutions and empower those people on the front lines."  2956

While the race to develop a safe coronavirus vaccine is on, there's new evidence other vaccines could help people survive the virus.A husband and wife professor team from Louisiana State University and Tulane University worked together on research about the MMR vaccine. That stands for measles, mumps and rubella.Most children get the vaccine. It could explain why kids are less impacted by COVID-19.Testing on mice found these kinds of "live" vaccines boosted cells' ability to fight off sepsis.Sepsis is ultimately what's causing organ problems and inflammation in many adults who have contracted the novel coronavirus.“The idea behind it is, if these live attenuated vaccines are inducing the cells that will inhibit or dampen the sepsis, that gives the regular immune response time enough to get rid of the infection,” said Dr. Paul Fidel, a professor at LSU.The results of the "live" vaccine test on mice were undeniable.Researchers also point to what happened on the USS Roosevelt, where more than 1,200 sailors contracted the virus. A few were hospitalized and one died.All U.S. Navy recruits get MMR vaccinations.The professors are starting a grassroots campaign for adults to get the MMR booster.“If we're right, wow you would have the cells that would inhibit or dampen the sepsis if you ever got infected with COVID and if we're wrong, so OK you have a booster for MMR and that can’t hurt you at all,” said Fidel.“I think this concept with live attenuated vaccines inducing this response that controls the inflammation as opposed to targeting the actual viral infection, it’s going to serve as a stop gap measure until we get a real legitimate vaccine developed that’s been shown to be efficacious and safe,” said Dr. Mairi Noverr, a professor at Tulane’s school of medicine.The MMR vaccine theory is being tested on primates now. There's a push for human trials, especially with health care workers and people in nursing homes. 1948

When you leave the big cities and head out to lesser populated areas of the United States, you realize President-elect Joe Biden may have won but President Donald Trump still enjoys plenty of support. "Since I was 18, I voted for Democrats, every time, but this year I voted for Trump," Scott Will, a new Trump voter in Westmoreland County, Pennsylvania, said. "My dad, he is a Joe Biden fan. He is calling me and teasing me about," Will said jokingly. While Trump is projected to lose the 2020 election, he did set voting records. Thus far, Trump has received more than 10 million more votes than four years ago. That is more votes than any American presidential candidate in history, except Biden. CHANGING REGIONS POLITICALLY While he lost the election, Trump did improve his margins in several key areas around the country. In Kenosha County, Wisconsin, Trump did 3% better. In Miami-Dade County, Florida, Trump did `12% better. And in Mahoning County, Ohio Trump actually flipped this county for the first time since Eisenhower. For perspective, this county, which includes Youngstown, Ohio, went for the Obama/Biden ticket in 2008 by 30 points. "The funny thing here is Trump stole the Democratic message. Can the Democrats steal it back?" Paul Sracic, a political scientist at Youngstown State University, said. Sracic said in defeat, Trump's legacy maybe forever changing politically places like Youngstown. Sracic said old trade deals, like NAFTA, were particularly toxic in this part of Ohio and voters rewarded Trump for getting rid of it and promising old jobs would come back. "Trump didn’t create these voters, they were waiting for Trump," Sracic said.WILL THESE VOTERS RESPECT BIDEN? At Thanos Restaurant in Mahoning County, Ohio, diners here know how Trump changed this area's politics. Ken Morrow eats here twice a day. In 2016, he voted for Bernie Sanders. In 2020 he voted for Trump. "For me, it's confusing," Morrow said, commenting on the election results and Trump's refusal to concede. His advice to Biden? "We need a lot of good paying jobs around here, everything is gone," Morrow said. Every Trump voter we spoke with said they would respect Biden come January 20th."I am very conservative," Jean Hasey said. "He’s going to be my president because I'm an American and a patriot," Hasey added. But she said -- uniting the country may be a tall task. "I think it’s going to be hard, very very hard," Hasey added. 2447

When it comes to scaring us, Hollywood sure likes to have fun with spiders. But it's no fun when you have a real fear of them. So it's no surprise when it came time to see one in person, Cassandra Kidd was a bit nervous.  "Oh God I'm scared!" Kidd exclaimed.   She mustered up her strength to hold Rosie the tarantula. And after just a few seconds the fear was gone.  "It felt kind of like a ladybug but more gentle," Kidd says.    Kathleen Lewis peered over the wall as her grandson held Rosie.  "No I'm not as brave as my four-year-old grandson," Lewis says.  Fear kept her from holding the spider herself.  "Too many legs moving," Lewis says.When it comes to overcoming fears like Arachnophobia experts say educating yourself in an environment where you feel safe can make all the difference. The Spider Pavilion at Butterfly Pavilion is an example. Arachnids of all sizes hang out above.  A belief that spiders want to jump down on you is one of many misconceptions Mary Ann Colley, Vice President of Science and Conservation at Butterfly Pavilion, has heard about spiders.  "People are always saying, 'Oh, I am going to eat spiders in my sleep,'" Colley says. "That's not true."Another? The idea they want to bite you."Spiders really don't want to have anything to do with us," Colley says. "They want to do their own thing, they want to hunt for their food, create their webs."  Colley says only a small amount of spiders have a level of toxicity to actually hurt us. Butterfly Pavilion hopes sharing facts can help overcome fear."We want to be respectful of nature around us," Colley says. "So we always suggest to observe so just to take a look you can get close but you don't have to touch."  Seeing spiders in a new light. And facing your fear head on. 1850

Wildfires continue to rip through the Western United States, destroying homes, businesses, and parks.“We know that they can get exponentially large very quickly,” James Marugg, division chief for San Miguel Fire and Rescue in California, said.Those on the front lines like Marugg say each year, the blazes seem to get more destructive.“Prevention is key and it’s defensible space, and the extra few minutes that defensible space gives us to be able to set up a perimeter, be able to get in and make the difference for someone's home," Marugg said.Defensible space is the area closest to a building, which is cleared of vegetation to help slow the spread of the flames.“Defensible space equals time,” Marugg said. Now, firefighters out west are getting some much-needed assistance in getting rid of some of that vegetation, from a team that’s hungry to help."Fifteen years ago, I’d say people need to wake up,” said Johnny Gonzales, the field operations manager for Environmental Land Management.Gonzales showed us a herd of almost 300 goats. It's not a petting zoo, but a work zone. “I see it as a work zone,” he said. “They’re coming in here and eating what we consider flash fuels. And that's basically broadleaf weeds, grasses, brush.”It's all that stuff you can see in between the trees in a field. The difference between before and after is noticeable.“Our goal is to bring back nature into the equation of fire control,” Gonzales said. “We’re not raising these goats to go to the market. These goats are true urban foresters if you will.”Hundreds of goats, right near the road and adjacent to homes.“Goats, depending on the time of year, can eat about 7 to 12 percent of their body weight,” Gonzales said. On this current project next to Cuyamaca College, the goats are getting through about an acre a day.“Our college actually sits on 165 acres of wildlife, and yet, you can see it’s completely overgrown. There’s non-native dry brush, and just a few weeks ago before the goats were here, we actually had a fire on campus,” Nicole Salgado, interim vice president of administrative services at Cuyamaca College, explained. “It poses a risk not only to our college but the surrounding community.”Hiring the goats just made sense for them, cost-wise.“To have the goats here, it’s 30 percent less than that of a human crew,” Salgado said.“You're as safe as your neighbor, and then it turns into you’re as safe as the block and your community. We’re now a whole state that's in need of fire fuel mitigation,” Gonzales explained.It helps out firefighters when it comes time to put out flames. Less dry brush means slower spread of flames.“You harden your house to keep a burglar from coming in, you need to do the same with wildfire. You need to look at it and think what are my vulnerabilities,” Marugg said.There’s also another trend he said is impacting the number of homes we lose to fire.“There’s more houses in the woodland area and we have to respond to them quicker, otherwise we lose more homes,” Marugg said.“Each year, the limits for the development lines still get higher and higher. More homes are being built in the mountains, Essam Heggy, a research scientist at the University of Southern California, said.“Our visual understanding of the environment we’ve been living in, in many places have been [associated] to the malls we visit and not to the environment that’s surrounding us. This disbelief in the complexity of our environment is the main driver of these hazards."As we near the end of wildfire season, Gonzales and his herders continue to clear up the spaces they can year-round, in a sustainable way.“I see this in the future becoming as common as trash pick up,” Gonzales said. “They really may be historically, and in the future, one of the greatest things of all time for fire fuel mitigation.” 3832
