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

EL CAJON, Calif. (KGTV) - An El Cajon homeowner knew he had a bee problem but never expected the "massive" hive discovered in his backyard."It's pretty incredible," said Herb Herbert.He first noticed a few bees about two years ago in the back yard of his home on Primrose Drive."The bees were coming in and out of a small hole at the bottom of my shed," said Herbert.The vent hole is one of several that led to open spaces under his shed. Last winter, the bees seemed to go away, but they were back in the summer. Herbert was stung once while mowing the lawn."There were 20 to 30 bees buzzing outside at any time," said Herbert.Herbert had plans for some entertaining in the near future, so last week he hired Bee Nice Wildlife Management. They peeled back the wood flooring in one corner of the shed and discovered a 30-inch long, 70-pound hive, home to between 100,000 and 150,000 honey bees."I had no idea the scope of what was under there. It was massive and amazing. The bee guy said we were lucky, the bees were getting set to expand the hive," said Herbert.As the local bee season gets underway, Herbert calls that possibility mind-boggling. While honeybees are generally not aggressive, they can still be dangerous.The bee removal company was able to relocate the hive and the bees. They say the size of the hive is not an indication of what may lie ahead. Because it's been a slightly above average rainfall, the region is likely in store for a typical bee season. 1482
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
(CNN) -- A new entry in "The Hunger Games" series is on the way, though fans will likely have to navigate the violent world without Katniss Everdeen.Scholastic announced an untitled prequel novel to the bestselling young adult series, set 64 years before the events of the eponymous first novel. The original trilogy followed heroine Everdeen in the fictional dystopia of Panem as she squared off against other teens in a fight to the death and eventually led an uprising against the oppressive ruling class.Author Suzanne Collins said the new story is set during the "Dark Days," 10 years after the start of the titular games that reduced citizens to savagery and murder to survive."With this book, I wanted to explore the state of nature, and what we perceive is required for our survival," she said, adding that the nascent days of the rebellion provide ample ground for new characters to "define their views of humanity."Set for a May 2020 release, the newest "Hunger Games" novel will arrive almost 10 years after the last, "Mockingjay," was published.The series spawned a movie franchise starring Jennifer Lawrence as Katniss with Stanley Tucci, Philip Seymour Hoffman and Julianne Moore. The four films earned nearly billion worldwide.Entertainment studio Lionsgate confirmed in a statement it had begun working on a new "Hunger Games" film to accompany the new novel."As the proud home of the 'Hunger Games' movies, we can hardly wait for Suzanne's next book to be published," company chairman Joe Drake said. 1528
