Frozen beef is out. Fresh beef is coming to McDonald's Quarter Pounders.McDonald's announced Tuesday that Quarter Pounders in every US store except for ones in Hawaii and Alaska will have fresh beef starting in May."The switch to fresh beef quarter-pound burgers is the most significant change to our system and restaurant operations since All Day Breakfast [in 2015]," said McDonald's USA President Chris Kempczinski.McDonald's has attempted to change its ingredients and menu over the last several years to shift customers' perceptions about the food, said Ernest Baskin, an assistant professor of food marketing at St. Joseph's University."This coincides with a national consumer demand for items that they perceive as healthier and higher quality," he said.The-CNN-Wire? & ? 2018 Cable News Network, Inc., a Time Warner Company.

Google and Apple teamed up to create a software that allows a COVID-19 tracking app to work. It’s part of a recent software update on smartphones.Now, Virginia is the first state to make an app using the technology. It's called COVIDWISE. It's similar to contact tracing but isn't exactly the same.COVIDWISE uses Bluetooth technology to measure distance between different people and how much time they've spent together. Both people need to have the app installed.Users will receive an alert if someone around them tests positive for coronavirus and it won't reveal who it was.While not everybody needs to have the app, the more people who do, the better.“For every one to two app users, you're potentially averting one infection, so I think that's a good take-home message,” said Jeff Stover, Executive Program Advisor at the Virginia Department of Health. “So, obviously the more of them there are, the more potential infections that we avert.”The app is really only meant to notify people if they've been exposed to the coronavirus. It's not meant to eliminate traditional contact tracing.“Traditional contact tracing is still important. It is still required. It's really how we get in touch with people to determine if they have questions, if they have prevention activities that they need to figure out,” said Stover.Another thing about the app is that it does not use location data. Virginia's health department says there's really no need for it, especially because that type of data doesn't really show the distance between people.Right now, the app can only be used in Virginia, but the state of North Dakota has said the app will be available for use there soon. 1680

Hate crimes across the U.S. have risen to the highest level in more than a decade. And federal officials have recorded the highest number of hate-motivated killings since the FBI began collecting that data in the early 1990s. An FBI report released Monday shows there were 51 hate crime murders in 2019. That includes 22 people who were killed in a shooting that targeted Mexicans at a Walmart in the border city of El Paso, Texas, in August 2019. There were 7,314 hate crimes last year, up from 7,120 the year before. Advocates want the federal government to mandate police agencies report hate crimes to the FBI. The current system is voluntary. 655

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
