Scientists have long warned of the effects of global warming and the possibility of more intense wildfires that burn for longer periods of time. Now, a new team of researchers is hoping to get a better understanding of how the smoke travels and what the tiniest particles could be doing to our lungs. "There's many things we’re still struggling to understand about smoke,” explains Joshua Schwarz, a physicist with the National Oceanic and Atmospheric Administration (NOAA). The group of researchers includes meteorologists and weather modelers, in addition to scientists. “All together, we are deciding which fires to target," Schwarz says. Amber Soja, with NASA, describes herself as the “fire person” of the group. Every day for the next couple of weeks, this group will create a flight plan, opening the door for another group of scientists inside this flying laboratory. “We've got tremendous range, and we're carrying a tremendous payload of information,” Soja says.This lab was once an Italian passenger airliner. It flies straight into the smoke of fires. "We'll have to look at what's the altitude of the smoke we want to be in, which direction is the smoke going, how far can we track that smoke," Schwarz says.Intake tubes on the outside of the lab bring in smoke particles that will be studied. Researchers are interested in learning how the smoke travels and what it does to our bodies when it’s inhaled. Pete Lahm, with the U.S. Forest Service, says studying the smoke is important because it impacts both public health and safety. “This info will help us make in the long run [make] better decisions on when we ignite fire and how we consider smoke impacts, and that's absolutely critical to our mission,” Lahm says.

Summer is in full swing, and with the warmer months comes the mosquitoes. Not only are the small insects pesky, they are considered the deadliest animal in the world, believe it or not. More than 700 million people around the globe get sick from mosquito bites, and more than 700,000 people die from those bites each year."We always see West Nile Virus peaks right after the Fourth of July weekend, because people have been outside and not protecting themselves," says Kylee Grenis, an expert on mosquitoes. Grenis helped us conduct an experiment to find out which bug repellent works the best.We purchased three mosquito traps. We sprayed one trap with DEET. The other with a top rated non-DEET spray called Skin So Soft by Avon. The third trap was a controlled trap with no spray.The traps were hung next to dry ice in a mosquito-infested park."We are going to hang some dry ice near those traps to simulate a human standing and breathing and hopefully that will help attract more mosquitoes to our traps," explains Grenis on the use of dry ice. After an hour, the trap sprayed with DEET had one mosquito. In the Avon-sprayed trap, there were no mosquitos. In the control trap, there were six mosquitos. The sprays kept the mosquitos away.As far as sprays go, Grenis says she still prefers DEET. "It is great at making you invisible to mosquitoes,” she says. “That blocks the receptors so that they can't detect your carbon dioxide signature." But, many consumers fear products with DEET are not safe. "I think a lot of the time people get it confused with DDT,” she explains of Dichlorodiphenyltrichloroethane (DDT), a chemical compound banned in many countries due to the danger it poses to wildlife and the environment.DEET is safe to use and just like the Avon spray, and both sprays are effective in keeping mosquitos away during the summer time months. 1872
