When it comes to saving lives, seconds count. And now, thanks to improving technology, drones are proving to be a game changer in an emergency.Dozens of people’s lives were saved last year with the help of drones, according to drone maker DJI.  The company said from May of 2017 to April of 2018, 65 people were rescued with the help of a drone. DJI reviewed media reports to come up with that number and included documentation in its recent report released this year.Firefighters, search and rescue teams and other members of law enforcement are using drones to survey an area much faster from the air than people can on the ground.“During a search and rescue operation we can see body temperature, Romeo Durscher, DJI’s Public Safety Integration Director, said.Drones carry more than simple cameras. They are now built to send back infrared images.Aeryon Defense USA, of Denver, has drones that can carry upwards of four pounds of payload. The company sells drones that can be used by police agencies and the military."That allows you to hook in a medical kit, radio, food, water (or) ammunition to provide life sustaining equipment," said Mark Holden of Aeryon Defense USA. “We can carry water, enough for one day, food, even ammunition resupplies and some explosives as well.”The company’s drones can also be programed to single out a person moving in the camera’s view, but ignore a tree blowing in the wind or wildlife.“This is just the beginning. Everything we do is about taking the load off the end user. We want to replace human functions on the battlefield with a robot,” Holden said.Drones have helped find a woman with dementia in Randolph County, North Carolina. She had wandered into a nearby field. Drones dropped a life preserver to flood victims in Sichuan, China before rescue crews arrived to save the victims. An infrared camera-equipped drone located a crash victim who became unconscious after leaving his car to get help. A similar camera also was used to locate lost tubers on a river in Vestavia Hills, Alabama.Technology allows drones to carry more weight than before. In the last one-and-a-half to two years, drone makers have improved how drones fly in difficult weather conditions."Search and rescue operations rarely happen on a beautiful, no wind kind of day so we had to design them to withstand the snow, the wind, and the rain,” Durscher said.They can help save the lives of rescuers too."You know what's ahead of you. It can alert you of a big cliff or flooded river,” Durscher said.Drones used by most rescue agencies run as much as ,000 to ,000. 2642

With millions of Americans getting tested for COVID-19 every single day, some are struggling with long waits for results.But now, researchers say there’s a much easier and faster way to test for the virus, and its right under your nose.“You scratch it, smell it, and then you have a choice of these different windows and you pick which one,” said Derek Toomre, Ph.D., a professor at Yale University School of Medicine.Toomre is part of U-Smell-It, a team that created a scratch-and-sniff app to help determine if someone has COVID-19 all through the sense of smell.“It's going to see how good your sense of smell is and if you do really well, you’ll pass,” Toomre said. “And if you don’t, it will say, ‘hey, you got something up.’”Despite being less accurate than a COVID-19 diagnostic test, this product is much faster and less costly. With results available in less than a minute and the cards costing 50 cents a pop, scientists say this smell app could outperform traditional tests at a fraction of the price.“We’re all familiar with the idea of testing people for fever as a way of finding people who have COVID,” said Roy Parker, Ph.D. a biochemistry professor at the University of Colorado, Boulder. “But that hasn’t worked very well.”Parker says with only about 20% of people with COVID-19 getting a fever, compared to 80% of people with COVID-19 reporting a loss a smell, a smell test is a much better indicator of COVID-19 infection than a temperature check.“It would make a big difference because you would identify people who have COVID, but they have such mild symptoms that they don’t know it and they’re out walking around potentially infecting other people and their family,” Park said.While commercially available, U-Smell-It is now looking for emergency FDA approval with the goal of getting their scratch-and-sniff cards into people’s hands and under their noses as quick as possible.“I can see people saying, ‘hey, this is not serious,’ and that’s fine, don’t take it serious,” Toomre said. “Let’s just try to do it and see if it works. And if you can’t smell that test and it’s saying, ‘hey, there’s something up’ well, you know, you should isolate and check out.” 2192

When natural disasters like hurricanes and wildfires hit, many who live dangerously close to the devastation are told to evacuate. Truck drivers who are delivering important shipments to those areas, don't have that luxury."In 2012, when I just got my CDL, I actually did relief supply for the hurricane that hit New York and New Jersey. I was teaming [with another driver], I was training and it hit. They asked me to stay on for another month," said Wayne Cragg, an experienced truck driver who owns and drives his own big rig and delivers shipments all over the country for various companies. Cragg has delivered supplies in the middle of and in the aftermath of countless natural disasters, including Hurricane Sandy. Often times, truck drivers are bringing necessary equipment or supplies, but in order to get them there, they have to take their own safety precautions so they don't end up victims themselves."When I did a run into New Jersey that hit pretty hard, when I first got there that first week they still had standing water when we had to back in [to the dock]," said Cragg.Cragg ensures he has three major supplies when heading to the scene of a natural disaster. "F.F.W. - fuel, food and water. It's huge, especially the fuel. A lot of other things you might be able to get off of other people, but fill up. One tanker full for our trucks, we can go a long time when you fuel up and you never know what's going to happen," said Cragg.Pilot Flying J, a national chain of truck travel centers, provides fuel, food, showers and other amenities for truck drivers when they're on the road. "As you track the weather, we all got a little lucky in terms of it. It took a little jog to the right. We had six stores down for a period of time but again, we recognize that we have amazing team members that work around the clock to get us up and running," said Pilot Flying J's Chief Operator, Jason Nordin. Nordin says they had to shut down two locations in Texas and four in Louisiana during Hurricane Laura. Their location in Lake Charles, Louisiana is still closed due to damage."We'll work with the local authorities. In certain markets there was a four mile evacuation order so we obviously work with them. In some cases we'll work with the local authorities to stay open a bit longer if certain law enforcement need to have fuel. We'll work out the last possible moment to make sure we stay safe," said Nordin. Often times, truck stops and gas stations have to follow evacuation orders during wildfires and hurricanes to keep their employees safe. Nordin says when they have to shut down, they try to get back up and running as soon as possible."We take great pride to stay open as long as we can and open as quickly as we can because we do recognize our role to take care of the first responders, take care of the trucking drivers that are trying to move things not only through the market to other markets but also for the local community, for those that live there," said Nordin.Wayne Cragg remembers being stranded at a truck stop while trying to deliver supplies to a wildfire in Oregon five years ago. "Unfortunately, it hit a big area on I-84 and that actually stopped me one night. It was the strangest thing because the fire kept going up and down the hills with the wind which they blocked us off on 84. I thought I was going to get by it because it was open before," said Cragg.Cragg and Pilot Flying J are thankful to all the truck drivers delivering supplies amid natural disasters this year. "Here we all are once again delivering to the places and the floods and hurricanes and fires. So, my hope is that the American public should just say we are always there when things happen," said Cragg.Bringing relief in an emergency, no matter the trek to get there. 3794
