As students return to school and employees head back to the office all with new safety protocols likely including wearing a mask, a new study from Duke University explores which masks are more effective.Spoiler alert: A fitted N95 mask, usually reserved for those in the medical community, performed the best in their test. However, since many Americans do not have access to those and have been using a mix of store-bought or homemade cotton and fabric facial coverings, Duke tested 13 other kinds of masks.The study, which was published Friday, was prompted when a professor at Duke’s School of Medicine was asked to assist a local group buying masks in bulk for the community. According to CNN, the professor wanted to make sure the masks they bought were effective.Researchers gathered 14 kinds of masks, including the professionally-fitted N95 mask, a bandana, homemade cotton varieties, and a surgical mask. They then used a dark room, laser beam and cell phone camera to record how many droplets (which reflect the laser beam light) each mask allows through.For each mask test and the non-mask wearing control test, the speaker was recorded saying “Stay healthy, people” five times. Each mask was tested ten times. 1229

AVON PARK -- A traffic stop in Avon Park, Florida, on Sunday led to what the Highlands County Sheriff's Office calls one of the largest drug seizures in recent memory in their county. Deputies confiscated enough fentanyl to kill nearly 40,000 people, as well as over a pound of heroin and nearly a pound of cocaine.Around 7:40 p.m., Deputy Seth Abeln saw a blue Ford Focus on North Central Avenue that had a tag light out. After Abeln stopped the vehicle, Deputy Ben Jones and K-9 Gentry were called to do a free air sniff of the vehicle. According to the sheriff's office, Gentry indicated there were drugs in the car.A search of the vehicle turned up:● 554 grams of heroin● 450 grams of cocaine● 99.6 grams of fentanyl● 975 oxycodone pills● 107 Xanax pills● 90 vape pens with liquid THCThe sheriff's office says a dose of 2-3 milligrams of fentanyl is enough to be deadly, meaning there was enough of the drug to kill 40,000 people using 2.5 milligrams as a fatal dose. To put that in perspective, that would be enough to kill nearly 40 percent of the people in Highlands County.The street value of the fentanyl is ,000. Add that to the ,000 of cocaine, ,000 of oxycodone and ,000 of heroin, and the total seizure is worth 0,000 on the street, not including the value of the vape pens.There was also a loaded handgun inside the car. deputies say. The driver, 40-year-old Ruben Ramirez-Rivera, was arrested and charged with:● trafficking cocaine● trafficking heroin● trafficking oxycodone● trafficking a controlled substance● possession of opium or a derivative (fentanyl) with intent to sell/deliver● possession of a Schedule III or IV drug with intent to sell/deliver● possession of heroin with intent to sell/deliver● possession of cocaine with intent to sell/deliver● felony possession of marijuana● possession of a weapon during commission of a first-degree felony● possession of drug equipmentRivera is being held without bond at the Highlands County Jail.“I’m very proud of the work done by the deputies involved in this arrest,” Sheriff Paul Blackman said. “To take this amount of drugs off the street is a huge accomplishment, and our county is safer because of it.”This article was written by Dan Trujillo for WFTS. 2249

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

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

AUGUSTA, Maine – Republican U.S. Sen. Susan Collins of Maine has won the hardest-fought race of her career, turning back a challenge by Democrat Sara Gideon and surviving to serve a fifth term.Collins, one of four candidates on the ballot, won a majority of first-place votes. That meant no additional tabulation rounds were necessary under Maine’s ranked choice voting system.Gideon has conceded, telling supporters on Wednesday that she called Collins and congratulated her on the win.Collins long touted herself in the fiercely independent state as a bipartisan centrist who’s willing to work with both parties to get things done.But opponents accused her of being an enabler of President Donald Trump, citing her votes to confirm Supreme Court Justice Brett Kavanaugh and for tax cuts that critics said favored the rich. 832
