As New Haven, Connecticut, Fire Chief John Alston Jr. spoke to reporters about a spate of drug overdoses on Wednesday, he heard shouting coming from behind him."We're getting another call of a person," Alston said.He quickly helped coordinate the response, and then returned to the microphone.That scene came on the same day that as many as 71 people in the area of New Haven Green were believed to have overdosed on some form of K2, according to New Haven police spokesman Officer David Hartman.New Haven Green is a large park and recreation area in the city's downtown.The patients included people of various ages and demographics, Alston said."It's a nationwide problem. Let's address it that way," he said. "It's a nationwide problem that people are self-medicating for several different reasons, and every agency -- police, fire, medical hospitals -- all are strained at this time. This is a problem that's not going away."New Haven police said one person is in custody.Rick Fontana, director of Emergency Operations for New Haven, said the patients had symptoms of increased heart rates, decreased respiratory rates and a lot of vomiting. Some people were unconscious, others were semi-conscious.No one has died, but two individuals are considered to be in serious, life-threatening condition. Some individuals who were released from the hospital needed to be treated a second time for an additional apparent overdose, Fontana said.K2 is a synthetic cannabinoid related to marijuana that is frequently laced with other drugs, said Dr. Sandy Bogucki of the Yale School of Public Health.In two cases, Narcan was not effective in the field, but a high dose of Narcan at the hospital was effective in combating the overdose effects. Authorities confirm the substance was synthetic cannabis and that other drugs weren't involved in the substance.The response from emergency responders has been "tremendous," Fontana said.He said authorities have been treating and sometimes transporting six or seven people at one time and the actions of first responders have been "lifesaving.""We hope this is coming to an end, but it's too early to tell."The-CNN-Wire 2162

AUSTIN, Texas -- Voting is a critical part of the democratic process.“That’s the way our democracy is supposed to work. As citizens, we have the right to vote, but it’s also a responsibility of citizenship,” Travis County Voter Registrar Bruce Elfant said.Before you can vote, you have to register. Elfant says he’s proud of the participation this election season in Travis County, Texas, where Austin is located.“We’re very excited," Elfant said. "This year, we hit 97% of all eligible citizens are now registered to vote and that is a high mark for us.”It’s not just a high mark, it’s a record for the county. Considering the median age is 34, many of those who registered were young adults.At the University of Texas at Austin, located in Travis County, both Democrat and Republican students have been working hard to register their peers. Grant Rommel is the Chapter President of University of Texas College Republicans.“Both political parties are going to want to get the vote out as much as possible to make sure that they have a secured win," Rommel said. "It’s really created kind of a race to see who can register more voters and it’s really exciting to see that because we’re getting everybody to participate and be involved.”Alexandra Evans is the President of University Democrats at UT Austin. She says she’s been telling fellow students that voting is a right many people have fought for. She hopes to convince others that their vote truly does count.“When our generation turns out, we get people who actually represent our interests and we don’t have to settle,” Evans said.The recent pattern of young adults actively participating in elections could bring results we have yet to see in our democracy.“Typically the younger voter is the less likely voter," Elfant said. "As far as I’ve been around, that’s been the case. But in 2018, we saw that starting to change and I think we’re seeing it change more this year.”“Young people forever really, I mean even since the voting age was lowered to 18, have had the lowest turnout rates of any voting age group,” Democracy Fellow Tova Wang said.Wang is a Democracy Fellow at the Ash Center at the Harvard Kennedy School. For 20 years, she’s been researching voter suppression tactics and ways to increase voter participation. She says politicians don’t usually speak to the needs of younger generations, but this, year she says young adults are demanding change.“They have a very strong sense of wanting to have their voices heard on climate, social justice, economic justice, and I am not surprised that in addition to taking to the streets and social media, they’re now making their voices heard through the ballot,” Wang said.Evans says that 97% voter registration is proof hard work pays off, especially since she says the process of registering to vote is more complicated in Texas compared to other states.“It’s such a convoluted system," Evans said. "It’s very frustrating.”She says she has to balance getting adults enthusiastic about voting while also explaining the lengthy process of registering. According to Elfant, 40 states allow people to register online, but that’s not the case in Texas.“We’re still a paper-based system," Elfant said. "You have to find a voter registration card, you have to fill it out, you may have to turn it in, you may have to find a stamp and an envelope. That’s the way the process works and young people don’t really work that way anymore, and 40 other states don’t work that way.”Evans adds college students move a lot and may not understand they need to register at a new address.“And if you miss like a signature, or they can’t decipher one number, sometimes your whole voter registration can get messed up and that’s really frustrating and discouraging,” Evans said.Nonetheless, it’s clear that won’t stop them in Travis County.“Especially in general election years, the contentiousness of it gets really high and it seems that this one is extremely high compared to others,” Rommel said.Both Rommel and Evans say they’d like to see the momentum of young adults voting continue into the future.“When we keep voting, we can make sure that people know – that politicians know – that their job to represent us is not being taken lightly, it’s not being taken lightly, and we’re watching them,” Evans said.“This generation is going to be a force to be reckoned with,” Wang said. 4390

At a White House news conference on Friday, leaders of Operation Warp Speed said that two coronavirus vaccines could receive emergency use authorization from the FDA in the coming weeks.In addition, Dr. Moncef Slaoui, who is the scientific head of Operation Warp Speed, projected that up to 20 million coronavirus vaccines could be shipped by the end of the year."If approved, they could be used for immunization in the U.S. population in the month of December," Slaoui said. "And we plan to have enough vaccine doses available for use in the U.S. population to immunize about 20 million individuals in the month of December, and another 25 to 30 million per month on an ongoing basis thereon."Given that doses of the two vaccines come in two doses, it could take many months and be well into 2021 before the majority of the American population is vaccinated against the coronavirus.The update came as the virus spreads throughout the country at an alarming and uncontrolled rate. At least 100,000 Americans are confirmed to have contracted the virus every day for the last 10 days, culminating in a record-shattering 153,000 cases on Thursday. Hospitalizations linked to the virus have reached all-time highs since the pandemic began, and deaths linked to the virus are beginning to tick up as well.The update also comes days after Pfizer announced that its vaccine candidate has been 90% effective in Phase 3 trials. The company says it is on track to apply for Emergency Use Status by the end of the month, meaning that some Americans could receive the vaccine before the year's end.New York Gov. Andrew Cuomo, who said his state would independently review vaccine candidates before authorizing distribution to the state, was a frequent target during Friday’s news briefing.“Vaccines will be allocated pro rata by population so we ensure fair and equitable across. We need the states who are part of the planning to accept the vaccine,” saidArmy General Gustave F. Perna, who is overseeing logistics and distribution for Operation Warp Speed. “We are working closely along with the CDC, the jurisdictions and states to ensure vaccine can safely and quickly get to those who need it first.”Trump blasted Cuomo for utilizing an independent review process separate from the FDA. "We won't be delivering it to New York until we have authorization to do so," Trump said. "That pains me to say that. This is a very successful, amazing vaccine that 90% or more. The governor, Gov. Cuomo will have to let us know when he's ready for it. Otherwise, we can't be delivering it to a state that won't be giving it to its people immediately. I know the people of New York very well, I know they want it. The governor will let us know when he's ready."Pfizer said it expects to have 50 million doses of its vaccine ready for global distribution by the end of 2020, and 1 billion doses globally by the end of 2021. That's why other vaccines are also being looked in hopes of getting as many Americans vaccinated as soon as possible. Trump and others on Operation Warp Speed confirmed that health care workers and the elderly would be first to receive doses of the vaccine. Dr. Anthony Fauci, the Trump administration's top infectious disease expert, predicted earlier this week that the vaccine would be widely available in April.Previously, Trump had suggested that a vaccine would have been approved in October and widely available by the start of 2021. Project Warp Speed leaders, however, credited the federal government's response to the virus even if the vaccine has not been distributed as quickly as previously suggested.Friday's remarks were Trump's first on-camera comments since Joe Biden was projected as the winner of the presidential election. Trump had not delivered comments to the press on-camera since Nov. 5, when at a press conference in the White House press room he falsely claimed he would win the presidential election on still-baseless claims of widespread voter fraud.Trump has appeared on camera just once in the last week — a Veteran's Day appearance at Arlington National Cemetery at which he did not speak.Trump's extended media blackout is out of step with the first four years of his administration. Trump has rarely shied away from speaking with reporters, as he often makes himself available for on-camera interviews with the White House press pool on the front lawn and has taken to calling friendly media outlets for phone interviews.However, since last Thursday, Trump has only delivered statements through his Twitter account, where he has continued to spread misinformation about the 2020 election. In the past week, Twitter has taken action on about 50 of Trump's tweets or retweets — be it adding a link to more information, adding a fact check or hiding the tweet from timelines completely. 4827

As we all prepare for a drastically different school year, parents are trying to figure out how to balance their work and virtual learning for their children as many districts across the country announce students will have at least a portion of their instruction at home.Uma Samynathan, owner and director of a Code Ninjas franchise in San Diego, showed her facility that includes a "Game Builders Club.”“We teach them how to build their own world rather than have them play a customized world on a tablet,” Samynathan said.She says her franchise was the first on the west coast. Two years in, she's encouraged and inspired by how fast kids learn.“What I love most is connecting with the kids and getting excited about the way they learn,” Samynathan said. “They are so unique, each one of them. If they (watched) a YouTube channel last night, they can tell me what was so interesting about the channel immediately. They’ll go to the rowlocks camera and start implanting that same thing."They've been doing virtual learning all summer, and they're about to do it a lot more. This time around though, many franchises like Samynathan's are offering parents a helping hand by providing assistance with a student's distance learning and provide some coding fun on the side."We can offer a STEM-based learning where they can learn coding, robotics, and they can do academics, homework,” Samynathan said. “If they’re going to cover a subject at school, we do it prior so they have a better understanding in doing that particular subject.”Some Code Ninja centers, like the one in Los Alamitos, California, sent out a survey to parents. They're taking about hiring an elementary school teacher to help proctor the learning so parents can work and kids can stay on task in their classroom while learning online. It's something that Nina Foster, mom to an 11-year-old in San Diego, is considering.“Preston is anxious to do more things on the outside again we may go back to doing one hour in the studio one at home, something like that,” Foster said.So far, Preston has kept up his coding skills through the center's virtual program and he's excelled.“He’s almost through the program,” Foster said. “He’s on the purple level -- it goes up to black just like karate. Once you get to the black level, you create your own app. From there, they’re joking that he could become a junior sensei until he’s old enough to work there.”Samynathan says Code Ninjas helps develop that out-of-the-box thinking."This is the best time for kids to get equipped with coding technological skills, they always want their tablet, they’re always playing games. Why not get creative why not learn to code on their favorite game?” she said.And what better time than now to help kids embrace the skills they'll need to propel them into a digital future? 2826
