Researches in the United Kingdom have found a purr-fect way for you to communicate with your cat.A recent study published in the online journal Scientific Reports found that cats will appear friendlier and more approachable to humans who use slow-blinking, eye-narrowing facial expressions, which psychologists at the Universities of Portsmouth and Sussex referred to as a "cat smile."In their first experiment, 21 cats interacted with their owners. The psychologists' team found that the cats would slow-blink if their owners slow-blinked at them first, compared to a neutral expression.In its second experiment, 24 cats and a member of the research team interacted. The study found that if the experimenter slow-blinked at them first, they were more likely to approach their outstretched hand than if they had given the cat a neutral expression."Collectively, our results suggest that slow blink sequences may function as a form of positive emotional communication between cats and humans," the researchers said. 1022

Republicans suffered setbacks to court challenges over the presidential election in three battleground states on Friday as a national law firm that came under fire for its work for President Trump’s campaign withdrew from a major Pennsylvania case. The legal blows began when a federal appeals court rejected an effort to block about 9,300 mail ballots that arrived after Election Day in Pennsylvania. The judges noted the “unprecedented challenges” facing the nation during the COVID-19 pandemic. Meanwhile, a Michigan judge found no evidence of fraud in refusing to stop the certification of Detroit-area election results. And in Arizona, a judge dismissed a Trump campaign’s lawsuit seeking the inspection of ballots in metro Phoenix.President-elect Joe Biden is projected win at least 290 Electoral College votes, and could add to his lead depending on a hand recount in Georgia. Biden is leading Georgia by more than 12,000 votes. 944

The resistance is real."The US Olympic Committee has yet to respond to CNN's request for a comment on the numbers of predicted absentees. 1031

Residents and businesses near a dam in North Carolina appeared to have dodged potential disaster Wednesday after an emergency at the location was called off.Earlier, heavy rains and a landslide in the western North Carolina mountains "compromised the integrity" of Lake Tahoma dam and triggered urgent calls for mandatory evacuations.Emergency officials said the dam was "at risk of imminent failure" and the weather service extended a flash flood warning for central McDowell County until 12:30 p.m.The National Weather Service cited reports early Wednesday from McDowell County emergency management officials that "water is spilling around the sides of Lake Tahoma dam. Evacuations ongoing south of the dam."But later, McDowell County emergency officials said Lake Tahoma had been inspected and deemed safe and a mandatory evacuation was halted. "The emergency at Lake Tahoma has been canceled. The evacuation order is no longer in effect. The engineer has performed a safety inspection and determined that the evacuation order is no longer needed," according to a statement on the McDowell County 911/Emergency Management Facebook page. 1147

President Donald Trump Saturday threatened to withhold federal aid from California to assist with relief from wildfires burning up and down the state.Trump blamed the state's "poor" forest management for the devastation caused by the wildfires."There is no reason for these massive, deadly and costly forest fires in California except that forest management is so poor. Billions of dollars are given each year, with so many lives lost, all because of gross mismanagement of the forests. Remedy now, or no more Fed payments!" Trump tweeted. 547
