(AP) — A medical team at a southwestern Louisiana hospital worked through the night to care for 19 tiny babies as Hurricane Laura slammed the region. Officials at Lake Charles Memorial Hospital for Women first had to transfer the 19 babies in the neonatal intensive care unit to the main hospital in the system after it became clear that the women's hospital could be swallowed in storm surge. Then the team of two neonatal nurse practitioners, 14 nurses, three respiratory therapists, and a doctor cared for the babies while the wind howled around them. But Dr. Juan Bossano said the babies seemed to weather the storm just fine. 638

With schools in Michigan closed during the spread of COVID-19, Grand Traverse Academy Principal Michelle Floering still wanted to deliver good news to a student in person. Floering decided to pay a visit to student Kaitlyn Watson who was working at a drive thru restaurant in Traverse City, Michigan. Floering informed Watson in person that she is the school’s class of 2020 valedictorian. “Thank you so much, I am so excited,” Watson said.“I couldn’t wait to come tell you,” Floering responded. The school has been on an extended spring break since March 16. Watch the announcement below: 601

 Two 250,000-year-old teeth from two Neanderthal children revealed that both of them were exposed to lead twice during their short lifetimes, the first known case of lead exposure in Neanderthals.An international team of researchers studied the two teeth, as well as one from a modern human child who lived 5,000 years ago. All of them are from the same archaeological site in southeast France. The results of their analysis were published Wednesday in the journal Science Advances."Traditionally, people thought lead exposure occurred in populations only after industrialization, but these results show it happened prehistorically, before lead had been widely released into the environment," said Christine Austin, study co-author and assistant professor in the Department of Environmental Medicine and Public Health at the Icahn School of Medicine at Mount Sinai. "Our team plans to analyze more teeth from our ancestors and investigate how lead exposures may have affected their health and how that may relate to how our bodies respond to lead today."And as with tree rings, researchers used the teeth to determine key events in the children's lives. During childhood, new teeth layers are formed each day, capturing chemical signatures that can be traced."Teeth record environmental variation based on the climate, even where you're growing up," said Tanya Smith, lead author of the study and associate professor at Griffith University. "That's possible because when you're growing, your teeth you actually lock in a record of the chemistry of the water and the food that you're eating and drinking. Because teeth have these tiny timelines, we can relate the chemistry to the growth to calculate ancient climate records. We can't do that with any other element of the body."They were able to determine that one of the Neanderthal children was born in the spring and that both children were more likely to be sick during the colder winter seasons. They lived through more extreme seasons with a greater variation in temperature than the modern human child who was also studied.The intact teeth had growth rings, which the researchers used to measure barium, lead and oxygen. Lasers targeted tiny spots in the teeth to map their chemistry and reconstruct ancient climate records. This reconstruction was able to map a weekly scale of variation, showing when the summer and winter seasons happened and how long they lasted. The researchers related this back to the individual's growth."This study reports a major breakthrough in the reconstruction of ancient climates, a significant factor in human evolution, as temperature and precipitation cycles influenced the landscapes and food resources our ancestors relied on," Smith said.The growth rings also provided evidence of nursing."We were able to identify milk intake through breastfeeding in one individual based on a trace element called barium," Smith said. "We were able to time that to the season."That individual nursed for 2? years, which is similar to modern human children who lived in hunter-gatherer environments. "This is something we may share in common with Neanderthals," Smith said. Unfortunately, although the Neanderthal child survived infancy, it did not reach adulthood. The ages of the children were not included in the study.The researchers believe that the children were exposed to lead environmentally, either inhaling or ingesting it."That must have come from natural deposits in the area, whether they were going into an underground environment or they were eating contaminated food that was incorporated into their growing bones and teeth," Smith said.Smith believes that this research emphasizes the different levels of information that can be taken from teeth."We've now got the ability to integrate ancient climate data with health history, nursing history and illness," she said. "To be able to get all that information from a single sample 250,000 years ago is a unique opportunity."But this doesn't just apply to studying those who lived before us."Dietary patterns in our early life have far-reaching consequences for our health, and by understanding how breastfeeding evolved, we can help guide the current population on what is good breastfeeding practice," said Manish Arora, study co-author and vice chairman of the Department of Environmental Medicine and Public Health at the Icahn School of Medicine. "Our research team is working on applying these techniques in contemporary populations to study how breastfeeding alters health trajectories including those of neurodevelopment, cardiac health and other high-priority health outcomes." 4648

 Ariana Grande is taking her fans behind the scenes of her "Dangerous Woman Tour" in a new docuseries.In it, she addresses the terrifying bombing that took place during her Manchester concert in May 2017, which killed 22 people.In the fourth episode of the docuseries, which dropped Thursday on YouTube Premium, the platform's paid streaming service, Grande writes a letter to her fans about the terrorist attack."I'm writing to you this February 22, 2018. It's been eight months since the attack at our show at the Manchester Arena. It's impossible to know where to start or to know what to say about this part. May 22, 2017, will leave me speechless and filled with questions for the rest of my life."Grande goes on to write, "Music is an escape. Music is the safest thing I've ever known. Music -- pop music, stan culture -- is something that brings people together, introduces them to some of their best friends, and makes them feel like they can be themselves. It is comfort. It is fun. It is expression. It is happiness. It is the last thing that would ever harm someone. It is safe. When something so opposite and so poisonous takes place in your world that is supposed to be everything but that ... it is shocking and heartbreaking in a way that seems impossible to fully recover from."Grande calls the tragedy "horrendous" in the letter."The spirit of the people of Manchester, the families affected by this horrendous tragedy, and my fans around the world have permanently impacted all of us for the rest of our lives. Their love, strength, and unity showed me, my team, my dancers, band, and entire crew not to be defeated. To continue during the scariest and saddest of times. To not let hate win. But instead, love as loudly as possible, and to appreciate every moment. The people of Manchester were able to change an event that portrayed the worst of humanity into one that portrayed the most beautiful of humanity. "Like a handprint on my heart" ... I think of Manchester constantly and will carry this with me every day for the rest of my life."The docuseries does not include any footage from the attacks, but does take viewers behind the scenes of the benefit concert she put together to raise money for victims families. 2277
