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

Attorney General William Barr took aim at his own Justice Department on Wednesday, criticizing prosecutors for behaving as “headhunters” in their pursuit of prominent targets and politically charged cases.The comments at a speech at Hillsdale College in Michigan amount to a striking and unusual rebuke of the thousands of prosecutors who do the daily work of assembling criminal cases across the country.Barr described the prosecutors as part of the “permanent bureaucracy” and said they were in need of supervision from “detached,” politically appointed leaders who are accountable to the president and Congress.“The men and women who have ultimate authority in the Justice Department are thus the ones on whom our elected officials have conferred that responsibility — by presidential appointment and Senate confirmation,” Barr said, according to his prepared remarks. “That blessing by the two political branches of government gives these officials democratic legitimacy that career officials simply do not possess.”As Attorney General, Barr has been aggressive in pursuing certain categories of prosecution himself, including seeking federal charges against those arrested in protests following the death of George Floyd. In fact, later on Wednesday, Barr said wants prosecutors to be aggressive in charging demonstrators who cause violence.So far, more than 300 people have been charged with federal crimes in the protests that erupted following the death of George Floyd.An Associated Press analysis shows that many are accused of serious crimes like hurling Molotov cocktails, burning police cars and seriously injuring law enforcement. Others are not accused of serious crimes, prompting criticism that the effort is a politically motivated effort to stymie demonstrations. 1790

Authorities in India have decided to hold off retrieving the body of the American national feared killed on North Sentinel Island amid concerns about a possible confrontation with the tribe that lives there.John Allen Chau is believed to have been killed by Sentinelese tribespeople after he visited their island home in the Andaman and Nicobar archipelago in November, breaching local laws strictly prohibiting contact with the isolated people.Indian police say Chau found local fishermen who agreed to take him near the island, before using a canoe the rest of the way. Days later, the fishermen -- who have since been arrested for facilitating his trip -- say they saw the tribespeople dragging his body around the island."We want to avoid direct confrontation with the tribespeople," Dependra Pathak, director general of police of the Andaman and Nicobar islands, told CNN when asked about the latest efforts to retrieve Chau's body. "We do not want to go there and create an unhappy situation."The decision to avoid a direct confrontation with the isolated tribe came after a series of meetings and reconnaissance trips made by the officials. Anthropologists and tribal experts were also consulted.By Sunday, authorities had mapped out the area with the help of the fishermen and observed several members of the tribe walking around the area where eyewitnesses claim to have seen Chau's body dragged and buried.However, despite ruling out any immediate attempts to land on the island, local police would not categorically rule out retrieving the body at a future date. "We are working on it. We'll firm up a plan very soon," said Pathak. 1660

Ashley Meadows has a tough job. As the gallery guide coordinator at the Hirshhorn Museum in Washington DC, she tries to get people to talk about modern and contemporary art.Consider the look of panic on people's faces when they're urged to express an opinion about a Jackson Pollock painting."It's hard to start a conversation with a stranger," Meadows, 33, said.But these days she has an ally in her efforts: a small humanoid robot named Pepper.The human-shaped robot stands four feet tall on one tapered leg, a shiny white body and big puppy dog-like eyes.Tucked into the curves of the Smithsonian's brutalist modern art temple, Meadows watches Pepper entertain guests. It dips at the waist, plays music and offers to take selfies -- the most popular of Pepper's tricks.This particular Pepper is one of a 25 strong army of robots at The Hirshhorn Museum and three other Smithsonians in the city, including The African Museum of Art, the African American Museum of History and Culture and the Smithsonian Castle.The robots made their debut this week.Pepper was donated by its manufacturer, the Japanese company Softbank Robotics.Pepper, first unveiled in 2014 in Japan, can be programmed for different use cases, whether it's at restaurant chain Pizza Hut, airports or now museums.But Pepper has limited functionality. It won't go off script but can tell guests a story, give them more information about a piece of art or "do something fun," like play music and dance with guests.Rachel Goslins, Smithsonian's director for the Arts and Industries Building, hopes Pepper's presence will encourage people to be more engaged as they walk through the galleries."I'm the mother of the robots," Goslins said.She decides which museums they're stationed at and and what they do. They're typically positioned in spots where she hopes for increased traffic or for people to linger longer."They're attracted to the robots like a magnet," Golsins said of its success so far.Pepper has already doubled foot traffic to a frequently missed section of the Museum of African American History and Culture -- the second floor educational gallery.But Pepper isn't perfect. Some visitors complained the robot couldn't speak or understand any language besides English. Others repeatedly asked Pepper questions it couldn't answer.Each Pepper robot has bodyguards to make sure the system is properly functioning, its software is updated to protect against hacking and that people don't harm the machines themselves.After entertaining visitors for most of the morning, Meadows powered down Pepper for a rest. The robot's eyes went dark and its white form slumped over like a puppet released from its strings."Say bye, Pepper!" said Meadows, wheeling the robot off the floor. 2758
