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

GREENCASTLE, Ind. — Several dozen students interrupted an event featuring actress Jenna Fischer at DePauw University Tuesday to protests recent racial incidents on and near campus.Many of them held signs with things claiming they are "afraid for their lives" after recent events. Fischer, star of the sicoms "The Office" and "Splitting Up Together" was at the university to discuss her new book, "The Actor's Life: A Survivor's Guide."University Spokesman Ken Owen, who was moderating the lecture with Fischer, said about 15 minutes into the program a group of students got up and began interrupting the event whistling, shouting and saying they were afraid for their safety on campus because of the recent racial incidents. Last week, a hateful message was found written in a bathroom at the university. The message, which read " All ******* must die -KKK," was written on a bathroom wall of the Inn at DePauw, a public building on campus. Another anti-Semitic and homophobic messages were also found. The video above was captured during the Tuesday evening protests by Shannon Samson. Another event being investigated by the university involves a hateful slur written in rocks at the DePauw nature park, which is owned by the university. Owen said there was a meeting with the school president Tuesday over the events and that have happened up until that point and they expect more meetings in the future. DePauw University issued the following statement on social media after the event.  1573

HAWAII — There was a close call at a preschool in Hawaii.The Hawaii State Department of Health says a classroom assistant mistook Pine-Sol for apple juice while serving snacks.The assistant at Kilohana United Methodist Church in East Oahu was preparing a snack for the children and grabbed a bottle of the cleaning liquid from a clean-up cart in the kitchen on November 27.The assistant apparently mistook it for apple juice because of its similar color, the school's director told the health department inspector.A classroom teacher smelled the cleaning product and stopped students from drinking it.EMS evaluated three students who took small sips of the cleaning liquid, but none of them needed treatment.One parent whose child was in the class says she was shocked a mistake like that could happen.The State Health Department says each year about a dozen people accidentally ingest Pine-Sol, and half of them are kids.CNN contributed to this report. 966

Gun raffles or giveaways aren't anything new, especially in rural parts of the country. But they're drawing renewed scrutiny after 17 people were killed last week in a mass shooting at a Florida high school.Some people are outraged that a lot of gun raffles are giving away AR-15-style rifles, the type used in multiple mass shootings. Police say Nikolas Cruz used an AR-15-style rifle February 14 at Marjory Stoneman Douglas High School in Parkland, Florida.A raffle currently underway in Kentucky is raising funds for the Central Kentucky Batcats, a girls' softball team. Buy a ticket and you could win a semiautomatic pistol or an AR-15-style rifle kit.While some people have complained about the raffle -- which began before the Florida shooting -- the store has mostly received calls of support, said Kenny Barnett, owner of Fully Loaded Inc., an outdoor and sporting goods store in Lawrenceburg that's providing the guns for the raffle."I've had calls both ways," Barnett told CNN. "For every one against, I've probably had 10 more asking where can they buy tickets?"'Truly astonished' 1103
