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

Lyft announced on Monday that they'll provide 60 million rides to and from vaccination sites for low-income, uninsured, and at-risk communities when COVID-19 vaccines become ready.To help launch the initiative, the ride-sharing company said in a press release that it's partnering with JPMorgan Chase, Anthem Inc., United Way, Epic, Centene Corporation, Modern Health, One Medical, National Hispanic Council on Aging, National Asian Pacific Center on Aging, National Urban League, and the National Action Network."Making sure people can get to vaccination sites when they need to is mission-critical to beating this virus," Lyft Co-Founder and President John Zimmer said in a statement. "This is an opportunity to use our collective strength to mobilize on a massive scale and serve our communities. We cannot let the lack of transportation be a factor in determining whether people have access to healthcare."To make sure people living in underserved communities can get vaccinated, companies and social impact organizations would provide free or discounted rides, while its corporate partners would directly fund the rides. The community partners will also route ride credits for those in need.The news comes after Uber announced last week that it would provide 10 million free or discounted rides to help people make it to their vaccination appointments. 1365

Many colleges are welcoming students back for in-person learning and dormitory living this fall semester. Looming over everything: Campuses could shut back down at any time.With COVID-19 cases still high, many colleges are developing shutdown contingency plans alongside their reopening arrangements.At the same time, the pandemic is fueling new debate about whether colleges should charge the same tuition for online and in-person classes. Tuition typically covers the cost of instruction — salaries, software, labs and such — and that cost at many schools may have increased.The University of North Carolina Wilmington, as an exception, has a different cost structure for online, hybrid and in-person classes. Still, it announced that students won’t receive a tuition refund if in-person classes move online this fall. And, after the pivot from its sister school at Chapel Hill, it told students to prepare for a similar transition if cases rise.That leaves freshman Owen Palmer weighing the possibility that the education he is paying for may not be the one he gets. “I’m taking a risk because (the university) mentioned they can’t do refunds,” says Palmer. For him, the risk is worth it, but he does wonder what he’ll do if the campus has to close.Here’s what he and other students can expect as the fall shapes up.Don’t expect a break on tuitionSome schools have cut tuition. Hampton University is offering students a 15% discount, bringing undergraduate tuition to ,519. Other schools are offering additional scholarships and grants.But tuition decreases and additional aid aren’t the norm.“If I had to make bets, I would say a lot of colleges will be (freezing tuition) until they get a better sense of the economy,” says Arun Ponnusamy, chief academic officer at the college admissions and application counseling company Collegewise. “But there will be other colleges that say, ‘We need money to run this school.’”That may be happening already. George Mason University in Virginia approved a tuition increase of 0. The University of Michigan approved a 1.9% tuition increase. Both schools are planning a mix of online and in-person instruction.Meals and housing refunds likelyMany colleges aren’t publicizing their shutdown contingency plans — or how refunds will work. But students can look to how their school handled refunds in the spring to gauge how fall might play out.Florida Agricultural and Mechanical University gave refunds for on-campus housing and meal plans, says William Hudson Jr., the school’s vice president for student affairs. If the campus has to shut down this fall, Hudson says the refund structure “would probably be the same.”Other colleges also offered direct refunds for students. For example, Temple University automatically deposited partial refunds for room and board in students’ bank accounts. The University of North Carolina Wilmington gave prorated refunds for room and board.But some colleges opted for account credit instead.The University of Arkansas refunded about 20% of room and board costs to student accounts. They haven’t announced an official plan in case of a fall shutdown, but staff members expect it’ll be the same.The University of Alabama offered a prorated refund for room and board, and parking. Students could take a cash refund immediately or apply that amount and an extra 10% as an account credit for the fall.How can you prepare?If you’re planning to return to campus housing, contact your school and ask about its shutdown contingency plans. You’ll want to know what factors would cause it to shut down again. This could be a campus COVID-19 outbreak of a certain size, an increase in local cases or other factors.You can’t stop a campus shutdown, but if you know the metrics your school is looking at, you can anticipate it and react more confidently.Make backup plans for housing if your campus closes. Determine if you’ll go home, stay with a friend, get your own apartment or something else. Communicate your intentions with those you plan to stay with or scope out affordable apartments in advance. That way, if the campus shuts down suddenly, you know exactly where you’ll go.Ask your college about emergency funds and grants if a campus closure will cause you financial hardship. Many colleges have funds available for students.Plan how you’d use a refund. If your school offers a direct refund, consider whether you’ll need that money for living expenses. If you don’t need the money for living expenses, send the refund back to your student loan servicer. Doing so will keep your overall loan balance down and save you money in the long run.More From NerdWalletPrivate Student Loan Relief for Borrowers in the Coronavirus CrisisCollege During COVID-19: Your Aid Questions AnsweredStudent Loan Borrowers: Don’t Wait on Congress for More ReliefCecilia Clark is a writer at NerdWallet.

LOUISVILLE, Kent. - A Louisville Metro Police Department command officer has been removed from her position and will retire from the department after an email criticizing people who are part of Antifa and the Black Lives Matter movement as "punks" who are not important.NBC News reports that Maj. Bridget Hallahan wrote the email to fellow officers which said, in part, "I know it is hard to keep our thoughts and opinions to ourselves sometimes, especially when we, as a whole or as an individual, become the target of people in the public who criticize what we do without even knowing the facts."These ANTIFA and BLM people, especially the ones who just jumped on the bandwagon 'yesterday' because they became 'woke' (insert eye roll here), do not deserve a second glance or thought from us."The email goes on to say, "Our little pinky toenails have more character, morals, and ethics than these punks have in their entire body. Do not stoop to their level. Do not respond to them. If we do, we only validate what they did. Don't make them important, because they are not. They will be the ones washing our cars, cashing us out at the Walmart, or living in their parents' basement playing COD for their entire life."Interim LMPD chief Robert Schroeder said Hallahan admitted to writing the email and took responsibility for her actions and said she will retire from the force on Oct. 1.This story was first reported by WLEX in Lexington, Kentucky. 1457
