 Conservative rhetoric about migrants -- like the group making their way through Mexico, the one President Donald Trump called an "invasion" -- might lead some to believe that migrants are a threat to American health, a strain on the health care system and damaging to the economy. But a new series of papers presented at a UN Intergovernmental Conference this week and published Wednesday in the journal Lancet says that, based on evidence, that's not true.Most migrants have a mortality advantage, or greater life expectancy, than people in their host countries, according to the new research. This was true for the majority of diseases.However, separating migrants from their families can be bad for children's health, as can keeping them in detention or continuously threatening them with deportation, the research showed.More than 1 billion people were "on the move" around the world this year, and a quarter of them were crossing international borders, according to researchers who worked on the report.With so many people on the move or having moved in 2018, the authors argue that "migration is the defining issue of our time," particularly as nationalist and anti-immigrant sentiment grows. 1267

 Special counsel Robert Mueller's team on Friday slammed a suggestion by Michael Flynn's lawyers last week that President Donald Trump's former national security adviser lied to the FBI not even a month into his tenure because he was caught off guard when two agents approached him.However, Mueller's office said it would not change its recommendation that Flynn receive no jail time, given he has accepted responsibility for his actions and cooperated with the special counsel.Mueller on Friday also released memos written by the FBI agents, and emphasized that when Flynn lied to them on January 24, 2017, about the substance of his policy conversations with then-Russian Ambassador Sergey Kislyak, he had already lied to several members of Trump's team and was "committed to his false story" that he and Kislyak did not discuss sanctions.Flynn later said he had lied, and will be sentenced next week. 916

 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

"The Davis School District apologizes for what took place yesterday. It does not tolerate speech, images or conduct that portray or promote hate in any form.The district is taking the matter very seriously and is investigating every aspect of the situation.The principal and teacher have been placed on paid administrative leave." 338

 DENVER, Colorado — The FBI agent who shot a man at a Denver nightclub when his weapon fell from his waistband while he was performing a backflip is scheduled to appear in court Thursday morning at 11:30 a.m. Eastern to enter a plea. Chase Bishop, 29, faces one count of second-degree assault, a fourth-degree felony. In July, Bishop's attorney revealed that a plea offer had been made to his client. Denver District Attorney's Office spokesman Ken Lane confirmed the existence of the offer at that time but said the details were not disclosed in court and thus won't be disclosed unless the deal is made. In a new update ahead of Thursday's hearing, Lane says there is no information about any plea deal in the works.Bishop turned himself in on the charge in early June. The shooting happened in the early morning hours of June 2 at the Mile High Spirits club. 919
