 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

"In the early morning hours of July 29, 2019, Mineral County Sheriff's Deputies assisted agents from the Federal Bureau of Investigation in a search of a residence located in Walker Lake, Nevada. This residence is believed to have been used by the Gilroy, California, shooter during the days prior to the July 28th incident. Mineral County Sheriff Randy Adams stated that 'Mineral County Deputies supported FBI agents by obtaining a search warrant for a unit in a triplex located in at Walker Lake. As this is an ongoing investigation, we are not able to comment further at this time.'" 594

"Strong leads" are being pursued to catch two men believed to be responsible for multiple fatal shootings across the Nashville area, police said. At this point, Metro Nashville Police said they are connecting three, different shootings with four victims – three of whom have died. The police department tweeted Monday morning that Chief Steve Anderson met with detectives in the case and said strong leads are being pursued. The first incident happened back on Aug. 8 in the Inglewood area when a 39-year-old woman was shot while walking her dog just before 1 a.m. She survived but police have confirmed the shooting left her paralyzed.Less than a week later, investigators said 31-year-old Kendall Rice was walking to work when he was robbed and fatally shot on Alta Loma Road in Madison. Kendall RiceThe third shooting linked to the spree happened around 3:30 a.m. Friday in East Nashville outside of The Cobra Nashville, a local bar.  Four people were heading to get a snack at a convenience store when they were robbed. Police said 33-year-old Bartley Teal and 30-year-old Jaime Sarrantonio were shot and killed. Jaime Sarrantonio and Bartley TealEarlier in the week, police officials said the three crimes and possibly two more could be linked but narrowed it down to the three shootings on Friday. 1361

(AP) — Scamp the Tramp will never win a beauty contest. But he's won an ugly one.The bug-eyed, dreadlocked pooch took top honors Friday night at the 31st annual World's Ugliest Dog Contest.Owner Yvonne Morones of Santa Rosa, California, won an appearance with Scamp on the "Today" show, ,500 in cash, another ,500 to donate to an animal shelter — and a trophy the size of a Rottweiler."He's Scamp the Champ, no longer Scamp the Tramp," Morones told the Santa Rosa Press-Democrat after the victory. "I think the audience saw his beautiful spirit and everything he's given back to the community."Scamp makes volunteer visits to schoolchildren and a local senior citizens center.PHOTOS: The World's Ugliest Dog contestants and winners over the yearsThe street dog from Compton was rescued by Morones in 2014 after she spotted him on Pet Finder."It was on the way home that I knew I made the right choice," she said in a contest press statement. "There we were, two strangers in a car on the way home to a new start. Bob Marley was playing 'One Love' and I looked over and little Scamp was bobbing his head. It was like he knew he had found his forever home."Scamp beat out 18 other contestants who showed off their droopy tongues, bowed legs, perpetually confused looks and other strange attributes.The contestants got to walk the red carpet and preen for adoring fans at Sonoma-Marin Fairgrounds in the heart of Northern California wine country.The competition, as they say, was fierce.Second place went to Wild Thang, a Pekinese with beady eyes and a disturbing tongue, owned by Ann Lewis of Los Angeles.Third place went to Tostito, a Chihuahua whose damaged ears and droopy tongue make him look like he just stuck his foot into an electrical socket. Tostito, owned by Molly Horgan of Falmouth, Maine, also won the Spirit Award.This year's People's Choice Award went to Meatloaf, a bulldog mix with protruding teeth owned by Denae Pruner of Sacramento, California.Everyone knows ugliness is in the eye of the beholder and, to a dog lover, there is no such thing as an uncomely canine. Weird-looking, maybe. Appearance-challenged, perhaps. Or, as owners of ugly dogs like to say, "unique."Like Willie Wonka, a sweet-natured pit bull abandoned after he was discovered to have a genetic malady that left his legs so bowed he could barely walk.With a chuckle, publicist Christy Gentry said the competition wasn't just about being ugly."Judges are looking for special attributes like hanging tongues, slobber, drool (the more the better). Maybe unusual patches of skin or hair," she explained.Last year's champion, an English bulldog named Zsa Zsa, with a tongue that hung nearly to the ground, endeared herself to the judges when she sneezed and drooled all over them.Soon she was headed to New York for national TV appearances. Sadly, Zsa Zsa died about a year ago at age 9.Another previous winner, Nana, made the cover of an album by the Grateful Dead spinoff band Ratdog.Organizers say the contest isn't just skin-deep. It's also about bringing attention to the needs of rescue dogs.Most competitors were previously abandoned or rescued from kill shelters in the U.S., found abandoned on streets or seized from unscrupulous breeders."What we're really doing is we're showcasing dogs that have been rescued and adopted and brought into loving homes," Gentry said. "These are sort of spokesdogs for adoption." 3417
