MADISON, Wis. (AP) — A divided Wisconsin Supreme Court has refused to hear President Donald Trump’s attempt to overturn his election loss to Democrat Joe Biden in the battleground state. The court on Thursday said the case must first wind its way through lower courts. Trump had argued that there would not be enough time to wage the legal battle that way before presidential electors cast their ballots on Dec. 14. An attorney for Trump says he'll file the lawsuit in circuit court. Biden defeated Trump by nearly 20,700 votes in Wisconsin. Trump is seeking to toss out more than 221,000 ballots in the state’s two biggest Democratic counties. 652

Microsoft founder and billionaire Bill Gates says he should pay more in taxes and that the government should require other superwealthy people like him to contribute "significantly higher" amounts."I need to pay higher taxes," Gates, who is worth over billion, said in an interview with CNN's Fareed Zakaria on Sunday."I've paid more taxes, over billion, than anyone else, but the government should require the people in my position to pay significantly higher taxes," he said.  499

Maybe music artist Moby was right, and “we are all made of stars.” New research suggests the calcium in our teeth and bones came from star explosions.Researchers from Northwestern University looked at a calcium-rich supernova with x-ray imaging, which provided a glimpse into the last month of the star’s life and ultimate explosion.The findings, published in The Astrophysical Journal, suggest a calcium-rich supernova is a compact star that gives off an outer layer of gas as it’s dying. When it explodes, the star’s matter collides with material, emitting bright x-rays.The explosion is so intensely hot and high pressure, it allows nuclear fusion to produce a massive amount of calcium in mere seconds. Typically, a star creates a small amount of calcium slowly by burning helium.Half the calcium in the universe likely came from calcium-rich supernovae.“These events are so few in number that we have never known what produced calcium-rich supernova,” said Wynn Jacobson-Galan, a first-year Northwestern graduate student who led the study. “By observing what this star did in its final month before it reached its critical, tumultuous end, we peered into a place previously unexplored, opening new avenues of study within transient science.”The observed explosion was named SN 2019ehk in the Messier 100 galaxy. If that sounds a little too fantasy, just know it was 55 million light years from earth.“Without this explosion, you wouldn’t know that anything was ever there,” Margutti added. “Not even Hubble could see it.”The team was able to look at images from the Hubble Telescope of the area of SN 2019ehk before the explosion to compare before and after.The researchers are working on a follow-up study that includes how the supernova is evolving after the explosion, according to statements made to CNN. 1821

Max Booth is from Redondo Beach and was excited to go to Maine for a summer camp for the second year. This year, that didn’t happen because of coronavirus, leaving Max at home. Then, his grandparents stepped in to save the day.Tim and Joy Booth live in Pacific Beach and said right around when Max found out he would be staying home for the summer, beaches and public places in their area started opening up, so they took advantage and planned a substitute summer camp for the 10-year-old.“It gave us real happiness to figure out how to make something that was at least a little bit similar to what he might have had,” said Joy.The trio spent the last week exploring the San Diego area, completing a long list of activities like cutting wood and barbecuing at a park, going to the beach, playing at a water park, practicing archery, hiking and observing nature, completing a junior park ranger program at the Cabrillo Monument and more. They even took the time to give back to the community, spending a day shoveling sand off of steps in Pacific Beach. They said a police officer and surfer stopped to thank them, the surfer adding that he had slipped on those steps because of the built-up sand.“We swept the stairs because we wanted to help people not get any injuries from slipping on the sand,” said Max.The week may have been different than a typical summer camp, but all three said they had the best time."I would just like to say thank you for being my parents and thank you for doing all this stuff for me," said Max."You’re welcome, Max. We love you," responded Tim and Joy. 1591
