 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

(AP/KGTV) — The U.S. Navy is expected to honor a World War II hero when a new aircraft carrier is named for Mess Attendant 2nd Class Doris Miller. "Dorie" Miller enlisted in September 1939 as a Mess Attendant Third Class. He was recognized for manning a machine gun on the USS West Virginia and returning fire against Japanese planes during the Dec. 7, 1941, attack on Pearl Harbor. He then helped rescue injured sailors as ship evacuations were ordered. Miller was awarded the Navy Cross for valor for his actions, the first African American to receive the award.This will be the second ship named after Miller and the first aircraft carrier ever named after an African American.“In selecting this name, we honor the contributions of all our enlisted ranks, past and present, men and women, of every race, religion and background,” said Acting Secretary of the Navy Thomas Modly. “Dr. Martin Luther King, Jr. observed, ‘Everybody can be great - because anybody can serve’. No one understands the importance and true meaning of service than those who have volunteered to put the needs of others above themselves.”Miller served aboard the USS Indianapolis from December 1941 to May 1943, before being assigned to the escort carrier Liscome Bay. He died while serving on a ship that was torpedoed by a Japanese submarine in November 1943, during the invasion of the Gilbert Islands. 1388

"I am truly sorry for my language and choice of words in a remark I made about Baker Mayfield that was captured on our live feed on TheLandOnDemand.I sincerely apologize for using a word that is a derogatory slur.There's no excuse for using that language in any context. It was said without malice but also without thought.It is well known that Baker and I have had our differences, and in the course of this experience, I've had to question my role in the erosion of the relationship. I have always endeavored to report and comment on him and the team fairly, and am shaken by these events. I will strive to be a better person and professional.I apologize to little people, Good Karma Brands, the Cleveland Browns, Baker Mayfield, to our listeners and to anyone who was offended by my remark." 802

SAN DIEGO (KGTV) – There’s a hidden gem right off the I-5 freeway in Mission Hills that took over 20 years to create. “It’s just been a wonderful thing,” said Edna Harper, designer of Harper’s Topiary Garden. Her garden sits on the massive hillside of her home and has been attracting visitors for years. More than 50 whimsical characters are featured, each one inspired by Harper’s world travels. The project started as a bet between Harper and her husband."My husband said to me, 'Oh, I don't think you can do this,'" Harper said. "He didn't know how much it was gonna cost him ... he said, 'alright if you win, I'll pay for the gardener and the water.'"

In addition to the elephants, the garden also has characters like cats, puppies, a whale, and Harper’s favorite: the hitchhiker. Harper’s gardener Pedro has been helping to bring her visions to life. “My favorite part is seeing all the people come by and take pictures,” Harper said. The garden has become her canvas and a place for your imagination to run wild. “Whatever you want it to be, that’s what my garden is,” Harper said. “It makes people happy, and that makes me happy.” If you decide to visit the property off Vine and Union in Mission Hills, the owners ask that you don’t climb or destroy the plans. They also suggest taking pictures from across the street to get the full view. 1638

(AP) -- Former President George W. Bush says the American people “can have confidence that this election was fundamentally fair, its integrity will be upheld, and its outcome is clear.”He says in a statement that “no matter how you voted, your vote counted.” And Bush says President Donald Trump has the right to request recounts and pursue legal challenges, with any unresolved issues to be “properly adjudicated.”Bush says now is the time when “we must come together for the sake of our families and neighbors, and for our nation and its future.”Bush says he's spoken with Joe Biden and thanked the president-elect for what Bush says was “the patriotic message” in Biden's national address on Saturday night after being declared the election winner.Bush says in a statement that while he and Biden have political differences, the former president says he knows Biden “to be good man who has won his opportunity to lead and unify our country.” 952
