Joe Biden is poised to decide in the coming month whether he will jump into the Democratic presidential race, inching closer to answering the looming question of whether he will make a third bid for the White House.One ally who spoke with Biden in recent weeks said that the former vice president indicated he was leaning toward a run. But if he reached a decision over the holidays, which he once indicated he hoped to do, he has not informed even his closest allies."He understands that he needs to make a decision relatively early in the process," the Biden ally told CNN, speaking on condition of anonymity to discuss private discussions. "He knows he can't wait."Biden's silence has raised questions among some Democratic donors and activists about whether he is ambivalent about running and uncertain about plunging his family into a bruising campaign, despite friends saying Biden has repeatedly argued he is 928

It might not have been a 13-0 win, but the U.S. women's national team shutout Sweden by a 2-0 margin on Thursday, to finish group play 3-0 in the Women's World Cup. The Red, White and Blue advance to the Round of 16 thanks to the trio of wins. The next match comes Monday against Spain. The US last faced Spain in January, which resulted in a 1-0 victory for the Americans.The USA outscored its opponents by an 18-0 margin during the three-game group stage. The 18 goals the Americans scored were the most in group stage play in Women's World Cup history. Ranked ninth in the FIFA rankings, Sweden was by far the toughest foe the U.S. has faced so far. Just three minutes into Thursday's match, Lindsey Horan scored to put the U.S. up 1-0. A Sweden own goal in the 50th minute put the Americans up 2-0. 815

In central Missouri, there’s a city of about 5,000 residents. But the small community is getting some national attention, thanks to one of its beloved residents. Lyn Woolford is not only Ashland, Missouri’s police chief, he ensures the children of Ashland get to school safely by directing traffic every morning. "Leadership includes participation," Woolford says. Crossing guard and police chief are just a few of the many hats Woolford wears. But even with so much responsibility as the newly appointed police chief, Woolford says he couldn’t give up his crossing guard gig after six years. “Evidentially I have a knack for this, and I do it well,” he says. That's why the school got together this year to let Chief Woolford know they appreciate his commitment. They nominated him for a special recognition, and Woolford won! The chief was named “America’s Favorite Crossing Guard” by the group Safe Kids Worldwide. His award earned the Southern Boone School District a ,000 prize to continue keeping roads safe. 1032

JERUSALEM, Israel — Israeli Prime Minister Benjamin Netanyahu says his government has decided to place anyone arriving from overseas into quarantine in a move to contain a growing coronavirus outbreak. Netanyahu announced the 14-day quarantine on Monday after consultations with Cabinet ministers and senior health officials. “This is a difficult decision, but it's necessary to protect public health. Public health comes before everything else,” Netanyahu said. 475

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
