Large parts of the US may experience record low temperatures as an Arctic blast sweeps across the Midwest and Northeast through the middle of next week.Nearly two-thirds of the country will be vulnerable to unseasonably cold temperatures."We are in a pattern where multiple waves of cold are moving in from Canada and impacting the Central and Eastern US," CNN meteorologist Taylor Ward said Thursday."One wave of cold came in late last week, another is moving in today and tomorrow, and the coldest blast by far moves in early next week."For much of the country east of the Rocky Mountains, the cold wave could mean temperatures 20-30 degrees below average.Cold-weather records could be brokenStarting Tuesday morning, record low temperatures are possible across Texas and Oklahoma, along with parts of the Ohio Valley.By Wednesday, there could be more than a dozen record lows in the Deep South and the Gulf Coast, Ward said.In parts of Mississippi and Alabama, highs aren't likely to rise out of the 30s Wednesday. For those areas, that's more than 10 degrees colder than usual even in mid-January.The cold temperatures have had unusual side effects in some places.In the Kansas City area, residents were saying they smelled an unusual odor.The National Weather Service in Kansas City 1300

LEBANON, Ohio — For most teens, senior year of high school should be filled with fond memories, but Lebanon High School senior Hunter Richardson won't get to enjoy them. According to the Richardson family, the district went too far when they 254

In regions of the United States and Mexico that are prone to hurricanes, aggressive spiders are evolving to survive and ride out the storm.When hurricanes rage along the Gulf of Mexico or charge up the East Coast, they can reshape an entire habitat in a short time. The winds destroy trees and spread debris for miles, putting new pressure on the creatures living in these environments.But how do creatures adapt when their habitats are so disturbed? Researchers looked at Anelosimus studiosus spiders that live in storm-prone areas along the coast to see how they changed. Their study was published Monday in the journal Nature Ecology and Evolution.These weather systems are called "black swan events": a surprising event with a major impact that is explained with the benefit of hindsight. They don't offer much lead time, so the researchers had to scramble to study the spider colonies before and after projected storms.The team monitored Subtropical Storm Alberto and Hurricanes Florence and Michael during the 2018 hurricane season. They tried to anticipate the systems' trajectories and study areas that included 240 female spider colonies, comparing them with areas where spider colonies were unaffected by such storms.The researchers returned to the sites hit by the storms 48 hours later. About 75% of the colonies survived the initial storm strikes."It is tremendously important to understand the environmental impacts of these 'black swan' weather events on evolution and natural selection," said Jonathan Pruitt, lead study author, evolutionary biologist and Canada 150 Chair in McMaster University's Department of Psychology, Neuroscience & Behaviour. "As sea levels rise, the incidence of tropical storms will only increase. Now more than ever we need to contend with what the ecological and evolutionary impacts of these storms will be for non-human animals."The A. studiosis spider species has two main personality traits that are inherited: docile and aggressive.Aggressiveness can be determined based on their speed, attackers pursuing prey, cannibalizing male spiders as well as eggs and their vulnerability to the invasion of predatory spiders.On the one hand, aggressive colonies are better at gathering resources in times of scarcity. But when deprived of food or subjected to overheating, aggressive colonies can also suffer from infighting."Tropical cyclones likely impact both of these stressors by altering the numbers of flying prey and increasing sun exposure from a more open canopy layer," Pruitt said. "Aggressiveness is passed down through generations in these colonies, from parent to daughter, and is a major factor in their survival and ability to reproduce."The researchers determined that after a storm passed, the colonies that aggressively pursued food and resources were able to produce more egg cases. The spiderlings also had a better chance of surviving into early winter.In areas that weren't hit by storms, docile colonies thrived.These findings were consistent even as the storms varied in duration, intensity and size. The researchers believe this shows that extreme events can shape animal behaviors. They would like to conduct more long-term studies to learn whether this is the case. 3250

In a world suffering a pandemic, cash is no longer king. A growing number of businesses and individuals worldwide have stopped using banknotes in fear that physical currency, handled by tens of thousands of people over their useful life, could be a vector for the spreading the coronavirus. While public officials and health experts have said that the risk to transfer the virus person-to-person through the use of banknotes is small, it has not stopped businesses from refusing to accept currency and some countries from urging their citizens to stop using banknotes altogether. 592

Kellie Chauvin, the wife of jailed former Minneapolis police officer Derek Chauvin, announced she is filing for divorce, her lawyer said in a statement to Minneapolis TV stations. Derek Chauvin was charged with third-degree murder on Friday, four days after holding a knee to the neck of George Floyd, who died while in police custody. “This evening, I spoke with Kellie Chauvin and her family. She is devastated by Mr. Floyd's death her utmost sympathy lies with his family, with his loved ones and with everyone who is grieving,” the lawyer for Kellie Chauvin said. “She has filed for dissolution of her marriage to Derek Chauvin.”“While Ms. Chauvin has no children from her current marriage, she respectfully requests that her children, her elder parents, and her extended family be given safety and privacy during this difficult time.” 851
