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

ASHLAND, Ore. -- In the Rogue Valley of southern Oregon, you’ll find rows upon rows of vineyards. Rob Folin is the winemaker at Belle Fiore in Ashland.Although the grapes are different, the dry climate is similar to Napa Valley, making it very ideal conditions for wine-making. However, just like other crops, the weather can have a huge impact on wine grapes. As a winemaker, Folin says he needs to know what his vineyards are facing and how to handle what Mother Nature throws at him.“Rain, snow, frost, smoke, fire, we’ve got it all,” Folin said.In the summertime, it can be clear one day and smoky the next.“Right during harvest or right before is when it’s the worst time to have smoke – which would be right now,” Folin said.Harvest season in southern Oregon typically starts in mid-September and goes until mid-October. Folin says one of the stressors for a winemaker is smoke taint. That’s when smoke gets trapped in the skin of the grapes giving them a campfire aroma and ashy texture. It’s a flavor very few people enjoy.“If your vineyard had a fire right next to it and you just had solid smoke coming in there, then you can really have this barbecue or campfire kind of aroma,” Folin said.Unless you send your grapes in somewhere to get tested, Folin says there’s no way to know your grapes have smoke taint until they go through fermentation. He says whether a grape is impacted or not depends on a lot of factors, and it’s very unpredictable.“Our vineyard here could be totally fine, and the one across the street, their resulting wines could be smoky, like it’s just how the wind goes, the intensity of the smoke, how long it was there, how close it was, did it settle overnight.”When it comes down to it, there’s only so much you can control. As of right now, not much can be done to prevent smoke taint, and smoky summers in the western U.S. seems to be the norm lately.Folin says winemakers that face a lot of smoke taint can make more white wines since white wines are fermented without the grape skin. Or they can market their wines to consumers as a smoky wine for those that like the taste. At the end of the day, Folin says winemakers have to go with the flow.“Just roll with it," Folin said. "Ya know, fix what you can. If you can’t do anything about it, what can you do? Do what you can do and move forward.”With the exception of one fire near the vineyard in the past month, Folin says it’s been a very great year for his vineyard. He’s hopeful something good can come out of 2020 after all.“With all the stuff that’s going on, maybe we’ll have the best grapes this year. I don’t know. Just going to count on that.” 2649

Astronaut Nick Hague was ready for a mission that would send him and cosmonaut Aleksey Ovchinin to the International Space Station to join a crew of three that was already on board the station. But just minutes into last week's flight on board the Soyuz MS-10 craft, the crew needed to abort the mission due to a booster failure. The incident marked the first aborted flight of a Soyuz craft in more than four decades. On Wednesday, Hague described the harrowing moments that followed after the booster's failure. “We were tossed back and forth inside the capsule a little bit and thrusted away from the rocket as soon as the launch abort system had recognized there was a problem with the booster," Hague said. That is when Hague's training and past as a US Air Force pilot kicked in. “My career in the Air Force has done a lot to help me prepare for stressful situations like this, whether it’s through deployments or my time in flight test where we have had to deal with failures in aircraft that you’re in and having to get down on the ground immediately,” he said. “We train endlessly to address those types of situations."After surviving an incident at 30 miles above the ground, Hague plans on making another attempt to visit the International Space Station in 2019.   1338
