 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

CHULA VISTA, Calif (KGTV) – For over 20 years, Tacos El Gordo in Chula Vista has been serving up authentic Tijuana style tacos, attracting people from all over the county. It also offers a sense of home for some of its customers. “The way they cook it, the taste the flavor the things they have on the side. It's the same like how it is in Mexico,” said Alexis Ortiz. SPECIAL COVERAGE: LIFE IN CHULA VISTA Ortiz used to work in the area for years but now resides in Mission Valley. Yet, she still finds herself at the well-known taco spot at least twice a month. It’s also a taste of home for Maritza Rodriguez, the smiling face you see behind the counter at Tacos El Gordo. “When I was six years old, my dad would bring me to the tacos like almost every week,” said Rodriguez, “I love the tacos, the food, it's part of my culture." Oscar Davila travels all the way from North County for his favorite tacos. “Tacos de adobada and carne asada tacos con todo,” said Davila. The long lines at the restaurant filled with customers eager to get their taco fix, from the fresh tortillas, meat packed with flavor, and several different menu items to choose from. The customers here say the authentic Tijuana flavors will continue to earn a place in the hearts and mouths of people daily.

"Live PD," which airs on A&E and embeds cameras in police units throughout the United States, has been canceled by the network amid calls for reforms of police departments throughout the US.The episodes aired with a slight delay, but gave viewers a glimpse of police interactions with the public.Variety reported the show’s cancelation, and show host Dan Abrams confirmed the announcement on Twitter. Abrams said on Tuesday that the show would continue on.“Shocked & beyond disappointed about this,” Abrams tweeted. “To the loyal #LivePDNation please know I, we, did everything we could to fight for you, and for our continuing effort at transparency in policing. I was convinced the show would go on.”Live PD’s announcement comes one day after “Cops” ended its 31-year run on television.Live PD became embroiled in controversy this week when the show announced that it no longer retained footage of a police-involved fatality in Austin, Texas, from a 2019 incident. Live PD said that because an investigation had concluded into the officers’ conduct, Live PD deleted the unaired footage.“This is a critical time in our nation’s history and we have made the decision to cease production on Live PD. Going forward, we will determine if there is a clear pathway to tell the stories of both the community and the police officers whose role it is to serve them. And with that, we will be meeting with community and civil rights leaders as well as police departments,” A&E said in a statement to Variety.Live PD frequently was the most-watched program on Friday and Saturday evenings since its 2016 launch. 1621

"As soon as we discovered the camera, we notified police. We are fully cooperating with their investigation, and we have notified all employees who work in the area where the camera was found." 201
