FULTON COUNTY, Indiana — “My two nephews and my niece were taken from me because somebody didn’t pay attention.”Elgin Ingle has to be strong for his family, especially his little brother, who lost three children when early Tuesday morning when they were struck and killed while crossing the street to board their school bus.“How he’s going to get past this. What do you tell your little brother when he’s just lost three of his children to someone’s negligence?” 470
Hot weather can increase the risk of natural disasters like droughts and wildfires, now, there is evidence extreme heat can increase harmful chemicals in the air.A study published recently in Science Advances looked at asphalt under different temperature conditions.“A main finding is that asphalt-related products emit substantial and diverse mixtures of organic compounds into the air, with a strong dependence on temperature and other environmental conditions,” says Peeyush Khare, a Yale chemical and environmental engineer and the lead author of the study, in a statement.The researchers took real-world samples of fresh road asphalt and put them in a controlled furnace with purified air. They heated the samples to temperatures between 104 and 392 degrees Fahrenheit, and measured the chemical components in the air.Total emissions nearly doubled when temperatures went from 104 to 140 degrees. At 104 degrees, 94 percent of the emissions measured were hydrocarbons.The group also exposed the asphalt samples to replicated solar heat, including UVA and UVB wavelengths, and found the rate of emission of potentially harmful chemicals increased. Showing that not only heat, but also solar radiation contributed to asphalt producing air pollution.Paved surfaces and roofs make up approximately 45% and 20% of surfaces in U.S. cities, respectively.Asphalt can be quite a bit hotter than the air around it, getting about 40 to 60 degrees warmer than the recorded air temperature.The researchers concluded that while policies and regulations have been put in place about car emissions and other forms of air pollution, asphalt should not be overlooked as a contributor.“It's another important non-combustion source of emissions that contributes to SOA (secondary organic aerosol) production, among a class of sources that scientists in the field are actively working to constrain better,” Drew Gentner, associate professor of chemical & environmental engineering, said. 1983

Halloween in Salem, Massachusetts, will look a lot different this year due to the coronavirus pandemic.City officials announced last week that stricter guidelines were going in place to prevent large gatherings in the "Witch City."According to CBS Boston, businesses will shut down early, the city will triple fines over Halloween weekend, and streets will be closed.The city canceled Halloween festivities back in early October due to health and safety concerns, city officials said. 492

HAMPTON ROADS, Va. - As coronavirus continues to rage across the country, scientists are inching closer to developing a COVID-19 vaccine.Dr. Doug Mitchell used to be a pediatric infectious diseases specialist at CHKD and EVMS. He is currently the medical director of CHKD Medical Group and a pediatrician at Norfolk Pediatrics.“If we’re able to stick to the science in developing the vaccine, then that would be comforting if we could stick to the science and develop an effective and safe vaccine,” said Mitchell.Mitchell said the speed at which researchers are developing a vaccine to combat COVID-19 is nothing short of a miracle, but sticking to the clinical science behind the advancement is key for an effective and safe vaccine - and that takes time.“The stated goal that I saw by the CDC and/or FDA of wanting a vaccine that shows at least 50% protection and six months of safety data, that takes time,” he said. “We need a chance to show the safety profile of any new vaccine under the parameters of following the best science that we could follow.”Mitchell understands the process involved in developing a vaccine.More than 20 years ago, he was an investigator in several pediatric clinical trials. Many of the vaccines that came out of his lab are still used in children today.While there are still growing concerns about vaccines, the benefits outweigh the risks.“The flu vaccine clearly saves lives, clearly prevents illnesses, but it’s not 100% protective either, but we know it does have benefits,” Mitchell said. “The advantage there is the flu vaccine has been out for decades and we know its safety profile.”Similar to the rapid speed of developing a COVID-19 vaccine, Mitchell said a vaccine for H1N1, better known as the swine flu, was quickly put on the market.“The difference is, we already had decades of history of flu vaccines and their safety, so all that happened was developing the same flu vaccine that was protective against a different strain,” he said. “That’s a different ballgame than starting a vaccine against a totally different virus.”While the research continues, the fight against COVID-19 is far from over.According to Mitchell, the spread of the virus decreases when you reach heard immunity where enough of the population is immune.This story was first reported by Antoinette DelBel at WTKR in Norfolk, Virginia. 2363
