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

Millions of people who are working or those hoping to return to work soon are depending on childcare. However, the industry is ringing the alarm, warning that most childcare providers are on the brink of closing permanently.“The fixed cost in these small businesses is so high that you are already running at very close margins and then with COVID, that pushed everything over the edge,” said Serah Kaiel.Kaiel has owned and run a small day care, Little Thinkers Montessori in New York City, for nine years. In March, her enrollment dropped by almost 80%, while her cost to stay open went up substantially.“It is like 0 to ,000 per child extra per year,” said Kaiel. "Like for the PPE, for the cleaning products, for all the things that go into keep it as safe and the best practices.”After operating in the red for six months, most providers are now coming to terms with the reality that staying open may not be a possibility much longer.“I represent women of color, I represent single mothers, and we are working on the front lines in this pandemic and we have the most to lose with the least amount of resources available to us,” said Kaiel. “There are moments when it is really scary.”A recent survey done by the National Association for the Education of Young Children shows that without some government aid, roughly 50% of childcare providers throughout the country could close permanently by the end of fall.Experts point out such a substantial loss of childcare could force more people out of the workforce. Low-income workers and women would be disproportionately affected.“It has this massive impact on the economics of communities. It has this massive impact on the economics of society, on women having the same opportunities that men do,” said Rhian Allvin. "It has a ripple effect that is really dramatic."Allvin is with the National Association for the Education of Young Children. NAEYC is calling on Congress to act and allocate billion for the industry in the next stimulus package.“We have really strong Democrat support. We have really strong Republican support. So right now, the hold up in Congress I don’t think is childcare,” said Allvin. "But young children and our field will suffer if they don’t get a stimulus package pass between now and the election.” 2298

MADISON, Wis. (AP) — The Wisconsin Supreme Court has rejected a request by the Green Party presidential candidate to be added to the state's November ballot. Wednesday's 4-3 ruling said the Greens' request came too late for any relief "that would not cause confusion and undue damage" just seven weeks before the election. Democrats had feared that Howie Hawkins' third-party campaign could siphon votes from Joe Biden and help Donald Trump in a state Trump narrowly carried four years ago. Adding Hawkins to the ballot also threatened delay and chaos in the effort to mail out absentee ballots to more than 1 million voters who have already requested them. Rapper Kanye West is still hoping to be added to the Wisconsin ballot. 736
