Summer might technically be over in Doha, Qatar, but if you were to visit the small, desert nation in the middle of the Persian Gulf this weekend, you would still think it is summer. Temperatures are expected to approach 100 degrees, which is relatively mild compared to the actual summertime temperatures in Qatar. In the summer, temperatures frequently top 110 degrees. Because of the year round extreme heat, and FIFA's mandate that stadiums that host the World Cup be open air, Qatar has been renovating and building stadiums that are both open air and air conditioned. A stream of cold air is funneled at ankle level under the seats. The cold air then travels down the stadium and onto the field. There are also vents at the top of the stadium. The technology relies on the physics of cool air moving downward. According to the Qatar government, the temperature in Khalifa International Stadium can drop to around 70 degrees, when it is nearly 100 degrees outside. Khalifa International Stadium opened in 2017, and was the first of eight stadiums expected to host World Cup games in 2022. A second stadium opened in May. Six more are expected to open by 2022. Next month, Khalifa International Stadium will host the Arabian Gulf Cup, which is a contest between the national teams for five countries. In December, the stadium will then host the FIFA World Cup. "Qatar's hosting of the Arabian Gulf Cup is another opportunity to test the country's event hosting expertise as we continue preparations for the FIFA Club World Cup in December and the FIFA World Cup in 2022," said Saud Al Mohannadi, vice president of the Qatar Football Association and chairman of the Arabian Gulf Cup local organizing committee.Qatar's bid to host the World Cup has not come without controversy. Following Qatar's winning bid, a multi-national investigation looked into how Qatar won the bid to host the 2022 World Cup, among other scandals tied to soccer sanctioning body FIFA. Dozens of FIFA officials were arrested in 2015, and several of whom have since been convicted for corruption. FIFA officials have been blasted by some for ignoring human rights concerns about Qatar, including its lack of a free press, lack of protection of guest workers, and its stance on homosexuality. 2282

Right now, nearly 2 million people are living with limb loss in the United States. But new technology is bringing hope, with a prosthetic that responds to what a person is thinking. Whether it's picking out socks or picking up LEGO blocks, Mario Gasbarro seems to be doing it all just fine, using what his kids affectionately call his “robot arm.” “They seem to enjoy it more than my old arm,” Gasbarro jokes. At just 34 years old, Gasbarro’s doctors told him the lump that had been growing on his elbow was a malignant tumor. As it grew, his doctors determined amputation was his best option. “I don't need my left arm to be able to love my kids and love my wife and to be there for them, so that was always a priority,” Gasbarro says. Now, he’s living with this prosthesis, which moves based on how he thinks and moves his muscles. “I want to open my hand. I think, ‘OK, open my hand and move the muscles to open my hand,’ and I just need to replicate that muscle movement each time I want to try to open my hand,” Gasbarro says.Dr. David Schnur with Presbyterian/ St. Luke’s Medical Center worked with Gasbarro through the process. “Instead of the patient learning the prosthesis, the prosthesis really learns the patient,” Dr. Schnur describes of the prosthetic arm. Through a process called targeted muscle reinnervation, Dr. Schnur attached the nerves from Gasbarro’s forearm that power the hand to muscles in his elbow. “And then what happens is when Mario thinks about closing his hand, instead of causing a muscle to fire down his forearm, it causes a muscle to fire up in his in his biceps,” Dr. Schnur describes. Those signals are then picked up by his prothesis through pattern recognition. “He contracts the muscles. That makes sense for him to close the hand and the computer on the prostheses picks that up and is then able to convert that specific signal into a hand closed,” Dr. Schnur says. Gasbarro says it's not second nature just yet, but he's getting there with practice.“I’ve never felt limited, or like, I’m not able to do anything,” Gasbarro says. 2084

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
