Researchers at the University at Buffalo say they've developed a low-cost new technology that can identify whether drugs are present. They believe the chemical-sensing chip could someday test someone or something for cocaine, marijuana or opioids just as quickly and cheaply as a breathalyzer tests for alcohol. 324

Republican Rick Saccone's campaign has instructed the four counties in Pennsylvania's 18th District to preserve ballots and voting machines, a first step in preparation for a potential recount following the close special election.With election day over and absentee ballots counted, Saccone trailed Democrat Conor Lamb by 627 votes in a district where President Donald Trump won by 20 points. But Saccone had not yet conceded the race Wednesday and now appears poised to challenge the result.Automatic recounts are not mandated in Pennsylvania congressional races, according to the state law. There is a process in place, however, for Saccone's supporters to request a recount when the counties have all the provisional and overseas military ballots and they have been counted.An attorney representing Saccone's campaign notified elections offices in Westmoreland, Washington, Green and Allegheny counties Wednesday of the preservation request, setting a 2 p.m. deadline for responses, according to letters obtained by CNN. All four counties complied, said Matt Gorman, a spokesperson National Republican Congressional Committee.The campaign is also challenging Allegheny County officials over the initial exclusion of one of its attorneys from the vote count, according to a letter to the county from Kathleen Gallagher, the attorney representing the campaign. "While we were finally able to obtain compliance with your inappropriate preconditions, the delay deprived the campaign of the right to have counsel present during the computation reporting process," Gallagher wrote.The campaign sought assurances from country officials that its lawyers would not be blocked from observing canvassing.Allegheny County spokeswoman Amie Downs told CNN that a person lacking authorization to be in the room where absentee ballots were being counted was blocked from entering, but was later allowed back in when the person was approved to be there.Meanwhile, the NRCC plans to launch a digital push to solicit reports from voters of irregularities they witnessed or difficulties they had in casting ballots, Gorman said. Bob Branstetter, a top Saccone aide, said Wednesday morning that the campaign fielded calls on election day from voters who were confused about the new Pennsylvania congressional map, which will be in effect during the November election. 2357

Racially charged protests across the world recently have sparked curiosity about racism and black history. It's created a demand some book stores weren't necessarily prepared for."On June 1 was the day that our internet sales just blew up," Debra Johnson with Matter Design Studio and Shop said. "Every black author title we had was sold out in about two hours."Debra Johnson and Rick Griffith are partners in running Matter Design Studio in Denver, Colorado."Matter was founded in 1999," Griffith said.In 2017, they decided to start selling books, but not just any books fill their store."Every book on these shelves has in some way changed our lives, or changed the lives of our children, or participated in our lives," Griffith said.On this day, they had just received boxes of books, mostly for online orders."Almost immediately when George Floyd was murdered, we had increased demand in books on anti-racist action," Griffith said. "Then it started rolling into demand on other topics as well that were related."The books were on anti-racism, racism, black history, and white rage, among other topics."It's like science. Learning about blackness is like science. You might understand some general principles, and you might even experience some things like gravity, but how many people can explain gravity? They can experience it, but they can't explain it. And race kind of works like that," he explained.As protests took place across the world, many were urged and inspired to educate themselves on the issues that led to the unrest. Stories about America's history of racism were shared across social media, as well as lists of books on Black history, books by Black authors, and where to find Black-owned bookstores."This is a similar phenomenon to I think what happened in the 1960s and 70's that I wrote about, and also in the early 1990's which is when there are intense periods of protest," Joshua Clark Davis, an Assistant Professor of History at the University of Baltimore said. "That fuels a drive by a lot of people, especially a lot of white people, who say I need to learn more about racism. I need to learn more about black culture."Davis is a historian. He wrote a book on the rise and fall of activist entrepreneurs, where he discusses the role Black-owned bookstores play, not just in Black history, but in American history."Going all the way back to the very first African American bookstore, which was in New York in the 1850's I believe, owned by a man named David Ruggles. He was an abolitionist," he said. "Black bookstores have always had a very tight connection with social movements, with activist movements. I think that's what we're seeing now.""We are activists by nature," Griffith said.From "vote" posters to sharing personal experiences through social media, Griffith and Johnson have always been involved."We've always been very tied into activism and our community," Johnson said.While fulfilling online orders, which helped them get by while shops were closed due to the coronavirus, the events that unfolded in May and June hit home for both of them."When George Floyd was murdered, not only did my black family have a great deal of trauma, we had to figure out how to heal. How they could heal," Johnson said."In some ways, it feels very normal for us to be in this struggle. In a very real way with a lot more people. And I love that there are a lot more people to work with, so many human beings who want the same thing. I think it's possible we can make some change," Griffith said. 3535

Republicans suffered setbacks to court challenges over the presidential election in three battleground states on Friday as a national law firm that came under fire for its work for President Trump’s campaign withdrew from a major Pennsylvania case. The legal blows began when a federal appeals court rejected an effort to block about 9,300 mail ballots that arrived after Election Day in Pennsylvania. The judges noted the “unprecedented challenges” facing the nation during the COVID-19 pandemic. Meanwhile, a Michigan judge found no evidence of fraud in refusing to stop the certification of Detroit-area election results. And in Arizona, a judge dismissed a Trump campaign’s lawsuit seeking the inspection of ballots in metro Phoenix.President-elect Joe Biden is projected win at least 290 Electoral College votes, and could add to his lead depending on a hand recount in Georgia. Biden is leading Georgia by more than 12,000 votes. 944

QUEEN CREEK, Ariz. — Conversations have been forced to change in children's classrooms. Many adults remember simply learning about a basic fire drill or what to do in a lockdown.But today, many teachers are having to teach kids what to do in case of an active shooter. Another safety net that is being used in places around Arizona, including Queen Creek Unified School District, is a donated, repurposed tool from the Queen Creek Fire and Medical Department: fire hoses. "They're cut into a certain segment. They are perfect to go over the hinges of our doors and that just adds this extra layer of security to our classroom," said Newell Barney Middle School science teacher Tammi Brewster. Brewster explained how the recycled and donated fire hoses from the fire department become a deterrent for any "bad guys" trying to get into a classroom and are now a part of their lockdown procedure called ALICE. ALICE stands for alert, lockdown, inform, counter and evacuate. Brewster said that the fire hose is part of a larger conversation with students regarding school shootings. It helps explain the procedure for active shooter or lockdown drills in a way that does not scare them, but empowers them. "It gives them a relief that, 'OK, all of this is going on in the news, in our society and I have choices I can make. I don't have to sit in a corner and be scared,' '' Brewster said. "The schools have their processes and their programs in place for a lockdown," said Queen Creek Fire Chief Vance Gray. "What we wanted to do was just assist by adding another layer of protection for the teachers and the students and the schools." Gray said his two children went to one of the schools where he has donated these fire hoses.While it is a piece of equipment he never hoped he would have to pass out, he knows taking action is the only thing to do. "If you can't change the way things are and make them exactly how you want them to be, then the best thing you can do is prepare," Gray said. He said they will continue donating their fire hoses whenever they go out of service.  2169
