As we're all focused on the current rollout of the COVID-19 vaccine, a technology known as thin-film freezing is getting a lot of attention. It's groundbreaking and could change the way we administer drugs or use medicine in general.You've probably heard about the need to keep the COVID-19 vaccine cold. It has to be so cold, in fact, that the shipment and transport are challenging. Well, what if that vaccine could be turned into powder?“What we’ve most recently been working on is the elimination of cold chain by storing as a powder, a dry powder where the drug is much more stable than if it was stored as a liquid or as a frozen liquid,” said co-inventor Dr. Robert Williams.Williams said it would eliminate the need for extreme cold storage and transport. The technology isn't new. He got a research grant and came up with it about 15 years ago.Williams, who is also a pharmacy professor at the University of Texas in Austin, said they were working on the technology and its multiple uses when the pandemic hit. And all of a sudden, they got a lot of attention.“We have published over 70 papers on the technology and using it for different products- it’s quite a mature process," Williams said. "We developed it because with other vaccines, the majority of the vaccine cost is in wastage because of this cold chain issue, so we published several key papers where we showed our thin-film freezing technology would protect vaccines - and you wouldn’t need cold chain storage.”Glenn Mattes, President, and CEO of TFF Pharmaceuticals added that the powders can be converted to topical preparations and they are currently working with the US Army to take some of the preparations and would then administer them directly through the eye.TFF is launching thin-film freezing into development through the FDA process. “I use the term ubiquitous because it is and disruptive because it is,” Mattes said. He added that they've explored their technology in the cannabinoid realm. But, as for the COVID vaccine, they're aiming for a second-generation usage.“To truly eradicate the pandemic, you have to have a global response," Mattes said. "The companies we’ve been speaking to certainly recognize the broad utilization of the technology but the application to the developing world, rural area, remote areas, where you can take a powder and inhale it or take the powder and reconstitute it has tremendous potential."Experts say it is only just the beginning as they launch their technology into a new world. 2511

Authorities have identified a Facebook post believed to have been made by the gunman who killed 12 people at a bar in California, a law enforcement official said.Ian Long, 28, burst into the Borderline Bar & Grill in Thousand Oaks and opened fire with a Glock .45-caliber handgun as patrons line-danced late Wednesday night.Long is believed to have posted the social media message around the time of the attack, according to the official, who is familiar with the investigation.In it, the writer says: "I hope people call me insane ... (laughing emojis).. wouldn't that just be a big ball of irony? Yeah ... I'm insane, but the only thing you people do after these shootings is 'hopes and prayers'.. or 'keep you in my thoughts'... every time... and wonder why these keep happening. " 796

BABSON PARK, Fla. — A second university in Polk County, Florida has announced that they will be joining a program that will allow its staff and faculty to legally carry guns on campus.The announcement comes just eight days after a gunman opened fire on a Florida high school killing 17 people.The Polk County Sheriff's Office, in partnership with Webber International University, is establishing the Sheriff's Sentinel Program to enhance the safety of an already safe and secure community of students, faculty, staff, and guests at the University's campus in Babson Park, Florida."Prayers are not enough," Polk County Sheriff Grady Judd said in a press conference on Thursday. “The only thing that stops a bad guy with a gun is a good guy with a gun."Sheriff Judd explained that each teacher or staff member will have to go through extensive training through the program before they are given a gun."My babies — your babies — are in that classroom, and that active shooter is coming down the hallway with that thousand yard stare and that gun in their hand, do you want somebody to step out and stop him? Or do you want him to go into the classroom and slaughter your babies?" 1194

As the Thanksgiving holiday approaches, college campuses across the country will empty out. Tens of thousands of students will head home for the break, and public health experts fear mass travel and indoor gatherings could spark a super spreading of the coronavirus.Within days of returning to campus this fall, Brianna DeWall contracted the coronavirus.“We went out to party, and with all my friends, got it,” recounted the Oklahoma State University junior. “So, we're assuming someone at that party had it and didn't know.”According to the Centers for Disease Control and Prevention (CDC), the return to college campuses in August and September coincided with a 55 percent increase nationally of COVID-19 cases in young adults ages 18 to 22.Next week, DeWall is headed home for the holidays, but she plans to get tested before she travels.“I will be flying, so I feel like that's a precaution I should take,” said DeWall.While her school isn’t requiring mandatory exit testing, other schools are.Penn State is offering free, voluntary exit tests. The University of Michigan has made exit testing mandatory, and New York State’s university system is also mandating a negative test result for all of its 140,000 students before they leave campus.“Some people may get a test that's not going to decrease the risk to zero, but it is going to decrease the risk substantially,” said Dr. Amesh Adalja, a senior scholar with the Johns Hopkins Center for Health Security.Dr. Adalja warns that without extra precautions like frequent testing, mask-wearing, social distancing, and self-quarantining ahead of the holiday, the risk of community spread is increased.“It is going to be a major challenge when you have your student body moved from campus back home and come back on campus because that's likely to introduce more levels of infection,” he said.Earlier this year, researchers at Ball State University tracked 7.5 million students at more than 1,300 universities and concluded that thousands of college students may have picked up COVID-19 while at densely-packed spring break destinations, only to return to infect others with the virus.Some schools like DeWall’s are not having students return to campus until January and have canceled spring break. But once again, testing is voluntary.“I think we should have to get tested before we come back,” said DeWall. “I think it's very careless that they aren't requiring us to get tested before we go home.”The CDC hasn’t issued any specific COVID-19 guidance on colleges and break, and while the American College Health Association encourages testing, it stops short of calling for it to be mandatory.“Colleges we know have been hot spots for infection, especially with off-campus activity,” said Dr. Adalja. “So, I do think this is going to be particularly challenging to accomplish.” 2839

ATLANTA (AP) — Two more Atlanta police officers have been fired over an incident in which two college students were pulled from a car during a protest against police brutality.Atlanta police confirmed Wednesday that Sgt.
