 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) - Pacific Gas & Electric Company says it will cooperate with any investigations stemming from a massive wildfire in Northern California.The utility told state regulators Thursday that it experienced a problem on an electrical transmission line near the site of the Camp Fire minutes before the fire broke out. The company said it later observed damage to a transmission tower on the line.PG&E spokeswoman Lynsey Paulo said Friday the information was preliminary and stressed that the cause of the fire has not been determined.RELATED: 10News Coverage of California WildfiresThe fire has killed at least nine people and destroyed more than 6,000 homes. It forced the evacuation of roughly 30,000 people in the town of Paradise, about 180 miles (289 kilometers) northeast of San Francisco.PG&E had planned earlier this week to launch a Public Safety Power Shutoff in portions of eight Northern California counties but canceled the plan, as weather conditions did not warrant the safety measure, according to a news release.PG&E later notified customers directly via automated calls, texts and emails that the potential Public Safety Power Shutoff had been canceled.RELATED: New California law helps utilities with wildfire lawsuits / Power company turns off lines to residents to prevent firesThe power company had notified approximately 70,000 customers in portions of Northern California of the potential that the company would turn off power for safety given forecasts of extreme fire danger conditions.   1570

 Former Director of National Intelligence James Clapper said Sunday that President Donald Trump's downplaying the threat posed by Russia's meddling in last year's election was dangerous to US national security.Speaking on CNN's "State of the Union" alongside former CIA Director John Brennan, Clapper said: "The threat posed by Russia, as John just said, is manifest and obvious. To try to paint it in any other way is, I think, astounding, and in fact, poses a peril to this country."Clapper, a CNN analyst, was responding to Trump's mixed comments about alleged Russian interference in the 2016 election. 619

(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

SAN DIEGO (KGTV) -- A potential partnership between the San Diego Unified School District and UC San Diego could help prevent the spread of the coronavirus within the school district.On Tuesday, officials with SD Unified and UC San Diego will discuss a collaborative effort that will provide COVID-19 testing -- with rapid results -- for district students and staff members every two weeks.Under the proposed testing program, all students and staff would be tested even if no symptoms are shown. The plan is to get their more than 100,000 students and 15,000 staff members tested twice a month.School Board Vice President Richard Barrera said, “We can’t wait for the federal and state government to provide so we can reopen our schools. We have to take the initiative ourselves ... being able to test on our campuses both students and staff is the best way to get large numbers of people being tested. UC San Diego would bring health professionals onto our campuses to do the testing.”San Diego Unified School District schools are currently in Phase One of the district's reopening plan. Under Phase One, which began Oct. 13, teachers have returned to campuses to provide appointment-based, in-person instruction for elementary school students identified as having “the greatest needs.”Phase Two of the district’s reopening plan would begin for elementary school students on Jan. 4, 2021. Middle and high Schools will start Jan. 25, at the beginning of the third academic quarter.SD Unified Superintendent Cindy Marten, district School Board President Dr. John Lee Evans, and UC San Diego Chancellor Pradeep K. Khosla are among the leaders expected to speak on the proposed partnership on Tuesday on the UC San Diego campus.The school board will vote on the million testing plan at its regular meeting Tuesday afternoon.The district wants to use the million from its budget, which includes funding from the CARES ACT to put up the initial costs to start up this program. But what happens next?"To sustain it -- it will require significant investments and that will need to come from the next stimulus package," said Barrera. 2140
