Melania Trump says she and President Donald Trump have faith in judges and the legal system to rule justly -- a statement that appears out of step with the president.At an event Monday in Pennsylvania, the president assailed as “very dangerous” a decision by Pennsylvania’s top court to allow mailed ballots received in the three days after Tuesday’s election to be counted.Later Monday, the first lady addressed a Trump rally in Huntersville, North Carolina. She expressed faith in the doctors, nurses, and scientists working on the coronavirus pandemic.Trump suggested Monday that he might fire Dr. Anthony Fauci after the election.Trump has disagreed with pandemic advice from Fauci, the nation’s leading infectious-disease expert and member of the White House coronavirus task force. 795

(AP) — The Mammoth Mountain resort in California's Eastern Sierra says it has had its snowiest May on record and skiing and boarding will continue into August.The resort said Friday the 29 inches (73.6 centimeters) that has fallen so far this month bests the old mark set in May 2015.Another 6 to 12 inches (15.2 to 30.4 centimeters) of snow is expected to fall on Sunday.RELATED: May snowfall in San Diego: Mount Laguna picks up more snowThe resort had so much snow during winter that it announced skiing and boarding would continue through the Fourth of July weekend. It now plans to extend the season into August, with no specific end date set.As of Friday, Mammoth had a season accumulations of 715 inches (1,816 centimeters) at the summit, and 489 inches (1,242 centimeters) at the main lodge. 828

LOUISVILLE, Ky. (AP) — Former Marine pilot Amy McGrath has overcome a bumpier-than-expected Kentucky primary to win the Democratic U.S. Senate nomination.She fended off progressive Charles Booker to set up a big-spending showdown with Republican Senate Majority Leader Mitch McConnell in the fall.McConnell is seeking a seventh term.Voting ended June 23, but it took a week until McGrath could be declared the winner Tuesday due to the race’s tight margins and a deluge of mail-in ballots.The outcome seemed a certainty early in the campaign but became tenuous as Booker’s profile surged.The Black state lawmaker highlighted protests against the deaths of African Americans in encounters with police. 708

  

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

  

McDonald's hopes new breakfast items will draw more customers to the golden arches.The company announced Tuesday that it would expand its breakfast menu. The new items, along with local deals and low prices, should help "win back customers at breakfast," said CFO Kevin Ozan during a call with analysts.With the new items, McDonald's is aiming to reverse a troubling trend: American customers are eating elsewhere.Sales in the United States grew by 2.4% in the third quarter, but that was mostly because people spent more. The number of American customers declined.Over the past couple of years, McDonald's (MCD) has tried a number of different strategies to boost its US business. It put self-order kiosks in restaurants. It added new menu items. And McDonald's added delivery.That helped boost sales among existing customers. But those initiatives, part of a massive effort to modernize its US restaurants, haven't helped McDonald's hold on to existing customers or bring in new ones.The company believes a revamped breakfast menu could help."It's very competitive out there at breakfast," said CEO Stephen Easterbrook. "We're still losing a little share ... it continues to be a battleground," he said. "We want to do better at breakfast."McDonald's didn't offer details on what the new items will be.In recent years, Taco Bell has found success with its breakfast offerings. The chain started serving breakfast in 2014 and now sells items like the naked egg taco, which has a fried egg for a shell. Dunkin' (DNKN), which offers a two-sandwich deal for breakfast, has also done well in the morning.Competitors have upped their game and McDonald's may have "lost a little bit of ground" on breakfast over the past few years, said Morningstar analyst R.J. Hottovy.McDonald's has already made some changes that may entice new US customers. It added coffee and  breakfast sandwiches at some locations. Easterbrook said it's too soon to tell whether those efforts are paying off.Hottovy thinks that McDonald's has a good shot at turning around its fortune."With a little bit of focus," he said, McDonald's "can get right back in.""They've gotten better about product innovation," Hottovy added. Customers responded enthusiastically to McDonald's new buttermilk crispy chicken tenders. That could bode well for the company's new breakfast item.Although McDonald's is struggling to win over customers for breakfast, it has used its popular breakfast items to drive growth in the past. Sales surged after McDonald's launched its all-day breakfast menu in 2015. 2628
