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

Hospital employees from the Naval Hospital Jacksonville have been removed from patient care after disturbing photos involving newborns went viral on Monday.The viral post, that has been shared more than 185,000 times, shows screenshots taken from the employees' Snapchat accounts. In the images, the employee is seen sticking up her middle finger to a newborn, captioned with "How I currently feel about these mini Satans." The post also explains that in one of the Snapchat screenshots, the "navy nurse" and her friend held up the baby, making the baby dance to rap music.The Naval Hospital Jacksonville posted a statement addressing the photos on their Facebook page: 702

Historic numbers of background checks to purchase or possess a firearm have been conducted in June. It's just the latest month with record-breaking numbers since the system was created in 1998. The FBI reported Wednesday that 3.9 million checks were done last month in what's a key barometer of gun sales. The numbers are driven by the crises that have roiled the U.S., including the coronavirus pandemic, an economic recession, protests over racial injustice and calls to reduce police funding. A group representing gunmakers says firearm purchases are a reasonable reaction to the political climate, while gun control advocates say they're concerned first-time buyers don't have enough training. 705

HONOLULU (AP) — Hurricane Douglas is gathering strength as it heads west toward the Hawaiian Islands on a track to potentially bring strong winds and flash flooding to the island chain over the weekend. The storm is getting stronger Thursday, becoming a Category 3 hurricane with maximum sustained winds of 120 mph. Cooler waters east of Hawaii and wind shear are expected to weaken the storm before it reaches the islands. 432
