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

He might have done it for Instragram or YouTube fame, but now a man who crossed a barricade guarding a hippopotamus enclosure at the Los Angeles Zoo is looking at potential trespassing charges after he was filmed spanking one of the animals.Video shows the man climbing the fence outside the hippo enclosure at the LA Zoo and sneaking up on two hippos, named Rosie and Mara. The man’s approach is very cautious, and then when finally close enough, he slaps one of the hippos on the rear before rushing back over the fence and taking a moment to celebrate his feat.The LAPD confirms they received a report of trespassing at the zoo and are investigating.In the video, Rosie, the hippo that was slapped, does not show much of a reaction, but her mother appears startled and looks up as the guy is still in the enclosure. It’s not clear if the man knows he’s being recorded, but clearly he’s showing off. The video started making the rounds on social media last week.While hippos at the zoo do have human interaction, this kind of treatment can create an unpredictable situation.The zoo released a statement Monday reading, in part:“The Zoo would like to remind everyone that it is never acceptable for a guest to enter the habitat of any animal at the Zoo, excluding our staff-supervised animal encounters. It is a privilege to observe these rare and endangered species, but they are still wild animals and their space must be respected at all times. Our first priority is always to keep our guests, staff, and animals safe.”Zoo officials have since put “No Trespassing” signs up around the zoo while police continue to look into the matter.According to California law, it is prohibited to enter zoo enclosures, and doing so may lead to a misdemeanor charge or infraction, L.A. Zoo spokeswoman April Spurlock told the Los Angeles Times.Zoo visitors are allowed to pet the hippos from behind a barricade for as part of its Hippo Encounter promotion. When the zoo unveiled the plan in 2016, People for the Ethical Treatment of Animals decried the practice. saying it violated the Animal Welfare Act, the only federal law setting standards for how animals are treated “in research, exhibition, transport, and by dealers.”PETA called for an investigation into the exhibit, pointing out that hippos kill more people than any other mammal on the continent of Africa.Rosie and Mara were actually featured in the zoo’s video promoting the Hippo Encounter in 2016.Rosie arrived to much fanfare on Halloween 2014, the first hippo to have been born at the zoo in 26 years. 2571

GLENDALE, Ariz. (AP) — The Arizona Coyotes have renounced their rights to their top 2020 draft pick after learning more about his bullying of a Black classmate four years ago.The team parted ways with Mitchell Miller after taking heat for selecting him in the fourth round earlier this month despite knowing of his 2016 assault conviction.Arizona acknowledged it knew about the incident when it selected Miller.President and CEO Xavier Gutierrez said discovering more about it, and the effect it had on bullying victim Isaiah Meyer-Crothers and his family led to this decision."We have decided to renounce the rights to Mitchell Miller, effective immediately," said Gutierrez in a press release. "Prior to selecting Mitchell in the NHL Draft, we were aware that a bullying incident took place in 2016. We do not condone this type of behavior but embraced this as a teachable moment to work with Mitchell to make him accountable for his actions and provide him with an opportunity to be a leader in anti-bullying and anti-racism efforts. We have learned more about the entire matter, and more importantly, the impact it has had on Isaiah and the Meyer-Crothers family. What we learned does not align with the core values and vision for our organization and leads to our decision to renounce our draft rights. On behalf of the Arizona Coyotes ownership and our entire organization, I would like to apologize to Isaiah and the Meyer-Crothers family. We are building a model franchise on and off the ice and will do the right thing for Isaiah and the Meyer-Crothers family, our fans, and our partners. Mr. Miller is now a free agent and can pursue his dream of becoming an NHL player elsewhere.The news comes after an extensive exposè of Miller's bullying Meyer-Crothers, who has developmental disabilities, back in Ohio, was published on Oct. 26 by the Arizona Republic.According to the Toledo Blade, Miller and another student were found delinquent on counts of assault and violating the Ohio Safe Schools Act.In court, Miller admitted that he and Hunter McKie made Meyer-Crothers "eat a candy push pop after wiping it in a bathroom urinal," the Toledo Blade reported back in 2016.Sylvania Schools suspended Miller after the incident.Miller becomes an NHL free agent effective immediately.According to ESPN, North Dakota head coach Brad Berry told the Grand Forks Herald that Miller was still part of their program. 2422

Here in the U.S., states are handling vaccine distribution in different ways.Most are going with health care workers in direct contact with COVID-19 patients first, but plans could change.“So, we need to set realistic expectations that there will be guidance that's different in different states. The guidance will evolve as we get more and more vaccines. And that doesn't mean anything's wrong or we've changed our minds, it’s just the way it's going to roll out,” said Stacy Hall, Director of Louisiana’s Public Health Immunization Program.Louisiana plans to let its hospitals and EMS distribute the first doses to their staffs. It’s a strategy not just to protect the valuable workers, but to hopefully get the public on board.“I'm really eager for them as the first group to really learn the science about the vaccine and step up and be vaccinated. I think that'll set our whole campaign in Louisiana and nationally on the right track,” said Hall.As for the cold storage of the vaccine, Louisiana doesn't see it as overly challenging.They also plan to use the state immunization information system to track who needs second doses and where the vaccine is being used most.“I want us to keep going back to that. There will be challenges and issues, but what a wonderful opportunity to make a change in the trajectory of the pandemic,” said Hall.The reality is, it will be months before the general public will get the vaccine at a pharmacy or drive thru. 1464

Geese are terrifying. Everyone knows this. Their bites hurt land they have no respect for children or the elderly. In fact, they are the second-most terrifying bird behind turkeys (large, tenacious) and ahead of crows (eidetic, vengeful).So this momentous trio of photographs showing a Canada goose absolutely trucking a high school golfer near Blissfield, Michigan, is just a reminder of the natural order of things. You can have, as one Twitter user put it, a "quiver full of bird maulers" and a whole high school athlete's worth of physical power, but the goose is going to win every time. It's science.The unlucky human sacrifice here is Isaac Couling, a member of the Concord High School golf team. According to Blissfield Golf Coach Steve Babbitt, Couling, 16, was competing in the Madison Tournament at the World Creek Golf Course in Adrian, Michigan, when terror rained down."The group just finished teeing off on hole #7 and were walking down the fairway," Babbitt told CNN in an email. "They were aware of a goose nest on their left which they were looking at but not bothering when from behind them and to the right came the guard goose (protecting the nest)."Then came a rather alarming escalation, a whole Shakespearean tragedy in three acts. The Blissfield Athletics Twitter account explained that Couling was caught off guard by the charging bird as he was keeping an eye on another, probably equally threatening, goose.As Couling attempted to flee the chaos he tripped, allowing the goose a clear coup de grace.Said Blissfield Athletics on Twitter: "And you thought golf was boring?"Massive credit should also be given to Devon Pitts of Blissfield, the photographer who caught this inspiring moment of nature in action."You can say (she) was at the right place at the right time," Babbitt said.Fortunately, Couling is fine despite his close brush with winged evil. He tells CNN he was able to pick up the game where he left off, though only on the goose's terms."My clubs fell out and the goose guarded my golf clubs, so I had to finish with my teammate's clubs," he said. "The coaches had to go out with golf carts (to chase it away) while I finished the hole."  2192
