George Floyd would have turned 47 years old Wednesday. In honor of his birthday, a new mural in Houston was unveiled showing Floyd’s image alongside messages encouraging people to vote.The brightly colored mural has two signs reading “be the change” and “go vote.” Floyd was born in Houston and a regular customer at the corner store where the mural is painted. 369

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

GUERNEVILLE, Calif. (AP) — Two communities in Northern California's wine country were accessible only by boat Wednesday after a rain-swollen river overflowed its banks following a relentless downpour across an already waterlogged region.The small city of Guerneville north of San Francisco "is officially an island," with the overflowing Russian River forecast to hit its highest level in about 25 years, the Sonoma County Sheriff's Office said in a statement."Nobody is coming or going from the Guerneville area at this time," said sheriff's Sgt. Spencer Crum. The nearby town of Monte Rio was also isolated by floodwaters and all roads leading to it were swamped.The still rising Russian River was engorged by days of rain from western U.S. storms that have also dumped heavy snow in the Sierra Nevada, throughout the Pacific Northwest and into Montana, where Gov. Steve Bullock signed an emergency order to help keep up the supply of heating fuel amid frigid temperatures.Snow from the storms closed roads and schools and toppled trucks and trees from Oregon to Montana and an avalanche in the Sierra prompted Amtrak to suspend rail service between Sacramento and Reno, Nevada.The Russian River topped 42 feet (13 meters) Wednesday afternoon, when television helicopter footage showed homes underwater and cars submerged. It could crest at more than 46 feet (14 meters) by Wednesday night, officials said. About 4,000 residents in two dozen river communities were ordered to evacuate Tuesday evening but officials estimate only about half heeded the orders, Crum said.Jeff Bridges, co-owner of the R3 Hotel in Guerneville, said he and others who stayed behind were well prepared to ride out the storm. He and employees spent most of the night moving computers, business records and furniture to second-floor room. Reached by telephone, Bridges said there was about 7 feet (2 meters) of water at his two-story home in Guerneville Wednesday but was not worried."As long as everybody is safe, dry and warm, it's all fine. You just ride it out," said Bridges, noting that this flood was the fourth he's experienced in 33 years.He added: "People in Florida have hurricanes, people in Maine have blizzards; we have floods," he said. "It's the price we have to pay to live in paradise."Several areas in California set record-high rainfall totals, including nearby Santa Rosa, which had nearly 8 inches (20 centimeters) of rain in one day. The often-waterlogged Venado weather station 5 miles (8 kilometers) from Guerneville recorded more than 20 inches (50 centimeters) of rain in 48 hours.In the Sierra Nevada, which has already seen a month of heavy snow, two Amtrak trains together carrying nearly 300 passengers stopped and reversed directions because of an avalanche that closed railroad tracks. Service on Amtrak's California Zephyr between Reno and Sacramento, California, has been suspended until weather conditions improve, Amtrak spokeswoman Kimberly Woods said.California officials were also concerned about potential mudslides in saturated wine country hillsides and in areas scarred by wildfires in 2017.A mudslide Tuesday near Monte Rio trapped a man and a woman before they were rescued, messy but unharmed."I fell into the mud when the tree fell over the top of me. It happened so fast you don't even know," Kear Koch told KGO-TV.Elsewhere in the area, several people had to be rescued from cars stranded while motorists tried to drive through flooded roads. Nina Sheehan, who is visiting from North Carolina, had to abandon her rental SUV after it got stuck in a flooded hotel parking lot."We made a decision to take the rental car through the waist-high water and we got two thirds of the way and then the car stalled," she said. "Do not try to go through any water over a foot high because you never know what you're going to find."Firefighters in Monte Rio worked through the night pulling people out of cars stuck in flooded roadways and getting people out of their homes as water approached, Fire Chief Steve Baxman told the Press-Democrat newspaper of Santa Rosa."We took 17 people out of cars and houses during the night. Too many people are driving into water," he said.Other waterways, including the Napa River, also were expected to overflow their banks as an ocean-spanning plume of moisture continued tracking through the West.___Rodriguez reported from San Francisco. 4401

FULLERTON, Calif. (AP) — An employee of California State University, Fullerton was killed in a stabbing in a campus parking lot Monday in what police called a targeted attack, though they were not sure of a motive.The victim was in his late 50s and worked in international student admissions at the sprawling campus in Orange County, police Lt. Jon Radus said. He was not immediately identified by authorities.A witness who called 911 said the suspect fled on foot, Radus said. Police found the victim inside a car with multiple stab wounds, he said."We do not know motive at this point for what occurred," Radus told reporters. "We do not believe there is a random stabber."The school, which is part of the 23-campus California State University system, enrolled more than 39,000 students last year. A commuter school in the middle of its host city, it is well known in the sports world for producing strong baseball teams.According to the university's calendar, the academic year was scheduled to start Monday.Authorities described the suspect as male with black hair and wearing black pants and a black shirt. 1119

Good news, "Jeopardy!" fans. The game show is returning for its 37th season, along with some familiar faces.The show announced new episodes would premiere Sept. 14, and it will have a fresh look amid the coronavirus pandemic.Host Alex Trebek will return as he battles pancreatic cancer.“I feel good, and I feel excited because once again, JEOPARDY! has demonstrated that it’s at the forefront of television programming,” Trebek said in the press release. “I believe we are the first quiz show to come back on the air in the COVID-19 era. On a personal level, I’m excited because it gets me out of the house. It gives me something to do on a regular basis, and I was missing that.”74-time champion Ken Jennings is joining the show as a consulting producer. 763
