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

HONOLULU (AP) -- About 8,000 people landed in Hawaii on the first day of a pre-travel testing program that allowed travelers to come to the islands without quarantining for two weeks if they could produce a negative coronavirus test.A new pre-travel testing program allows visitors who test negative for COVID-19 to come to Hawaii and avoid two weeks of mandatory quarantine.The state-run testing program is an effort to stem the devastating downturn the pandemic has had on Hawaii's tourism-based economy.However, gaps in the program coupled with increasing cases of COVID-19 across the U.S. and the world have raised questions about whether Hawaii is ready to safely welcome back vacationers. 702

Hospitals are fast approaching capacity a number of states, and the Miami area again ordered restaurants closed as the number of confirmed coronavirus cases and hospitalizations began to climb. The dour news comes as the U.S. emerged from a Fourth of July weekend of picnics, pool parties and beach outings that health officials fear could fuel the rapidly worsening outbreak. The see-saw effect of eased restrictions and then increases in cases is seeing a number of states reverse course and start to clamp down.To dampen the spread, Miami-Dade County closed all beaches over the July Fourth holiday. The beaches are expected to reopen on Tuesday. Over the course of the pandemic, Miami-Dade County has had more than 1,000 deaths and 48,000 COVID-19 cases, according to Johns Hopkins University data. 811

Harvey Weinstein turned himself in to authorities Friday morning and was arrested and arraigned on charges of first- and third-degree rape and committing a criminal sexual act in the first degree, according to the Manhattan District Attorney's office.The charges stem from incidents with two separate women in 2013 and 2004, the district attorney said in a statement, and were the result of a joint investigation between police and the Manhattan District Attorney's office.Weinstein's attorney Benjamin Brafman told reporters outside the courthouse that his client plans to plead not guilty to all of the charges.As part of the agreement between Brafman and the DA's office, Weinstein's bond was set at million. He'll be required to wear a GPS monitoring system and is only allowed to travel within New York state or Connecticut. 841

From 2000 through 2018, 459 children have died from accidental furniture tip overs, which are preventable fatalities that can be stopped by anchoring furniture to a wall.In response, the US Consumer Product Safety Commission is launching a public service announcement campaign called "Even When You're Watching.” The campaign will show the dangers of leaving furniture unanchored. The campaign includes “terrifying” footage of tip overs caught on video.In addition to the number of fatalities, the CPSC estimates that every 43 minutes, a child is injured by furniture tipping over."Even when adults are in the same room with children, dangerous tip-overs can occur," said CPSC acting chairman Robert Adler. "Many parents and caregivers do not know about this hidden hazard, or believe that they can prevent a tip-over by watching their children, but these incidents still happen. We urge adults to Anchor It! and to tell their friends and family to do so, too, because these tragic tip-overs can happen in the blink of an eye."According to a CPSC survey, 80 percent are aware that furniture can tip over, but just 47 percent say they have their TV anchors, and 55 percent say they have anchored furniture in their home.The CSPC offers parents the following tips:To protect children from a tip-over incident, follow these safety tips in any home where children live or visit:Anchor TVs and furniture, such as bookcases and dressers, securely to the wall.Always place TVs on a sturdy, low base, and push the TV back as far as possible, particularly if anchoring is not possible.Avoid displaying or storing items, such as toys and remotes, in places where kids might be tempted to climb up to reach for them.Store heavier items on lower shelves, or in lower drawers.If purchasing a new TV, consider recycling older ones not currently in use. If moving the older TV to another room, be sure it is anchored to the wall properly.Keep TV and/or cable cords out of reach of children.Supervise children in rooms where these safety tips have not been undertaken.To view the public service announcement, click here. 2112
