While giving remarks at the White House Wednesday, President Donald Trump announced his administration is lifting sanctions he imposed on Turkey after the country chose to attack the Kurds following a US retreat on the Turkish/Syrian border earlier this month.Trump said that he would re-imposed sanctions should Turkey choose to attack the Kurds or other religious minorities in the country. He added that a small amount of US troops would remain in Syria to protect oil reserves.Trump also said that the ISIS prisoners that had escaped following the Turkish attack on the Kurds had "largely been re-captured," but did not go into specifics. Trump did not respond to a question posed by reporters about members of the Trump administration's top envoy who made comments to the contrary.The ceasefire on the Turkish/Syrian border comes after Trump ordered American troops be removed from the area earlier this month. Their removal prompted a Turkish attack on the Kurds, an American ally in the region. A ceasefire was struck between late last week and has largely held thus far.Trump's comments will come one day after William Taylor, an American diplomat in Ukraine, 1180

US Customs and Border Protection will not vaccinate migrants, even though three children who had been in US custody died after contracting the flu.The cases all occurred since December."In general, due to the short-term nature of CBP holding and the complexities of operating vaccination programs, neither CBP nor its medical contractors administer vaccinations to those in our custody," according to a statement Tuesday from CBP.Migrants are supposed to held in CBP custody for 72 hours or less, but often remain there for longer.After leaving CBP custody, children without parents are sent into the care of the US Department of Health and Human Services, where flu vaccines are distributed, according to Evelyn Stauffer, a spokeswoman for the Office of Refugee Resettlement, a part of HHS.Public health experts had strong reactions to CBP's statement, saying the department should be able to vaccinate migrants, even if they're in CBP custody for only a few days."I think their answer is completely inappropriate," said Dr. William Schaffner, an infectious disease specialist at Vanderbilt University and an adviser the US Centers for Disease Control and Protection. "They ought to be able to do this. They create facilities that encourage the spread of infectious agents, with flu at the top of the list."Flu activity in the United States typically begins to increase around October and many US pharmacies already have flu vaccines available.Children younger than 5, and especially those younger than 2, are at high risk of serious flu-related complications, according to the CDC. Flu seasons vary in severity, but thousands of children are hospitalized each year related to the flu, and some children die. A flu vaccine offers the best defense against getting flu and spreading it to others, the CDC said.Concern about contagious diseasesOn August 5, two members of Congress 1891

When Amy Anderson and her son walked into George Washington High School years ago they felt a gut-wrenching reaction, coming face to face with a larger than life mural depicting images of slavery and dead Native Americans.Tuesday evening, after decades of debate and outcry, the San Francisco Unified School District unanimously voted to cover up this 1936-era fresco, "Life of Washington."A fight started in the 1960sThe mural was commissioned by the US Government in 1936 under a New Deal art program and painted by well-known muralist Victor Arnautoff.During the Civil Rights Movement in the late 1960's, members of school's Black Student Union called for the removal of the mural.Instead of removing the mural then, the District hired black artist Dewey Crumpler to paint a "response mural," showing Native Americans and African Americans in a more positive light.Three years ago, the call for removal was reignited when Anderson's son Kai decided to enroll at Washington High.A Native American student at Washington HighAnderson and her son are Native American. Kai told his mom he would walk into school with his head down everyday so he would not have to see the murals on the wall."They (Native students) actually see themselves and their ancestors up there on those walls and they feel pain," said Anderson.In late fall of 2018, Anderson and fellow indigenous activist Mariposa Villaluna drafted a resolution to send to Mark Sanchez, a school board commissioner. The move resulted in the creation of the district's Reflection and Action Committee to decide what to do about the "Life of Washington" mural.In February, the committee recommended to the school board that the mural should be covered in white paint before the start of the 2019 school year.At odds with school valuesThe committee argued that the mural did not live up to the district's student-centered focus and did not represent its values of social justice, diversity, and unity. It added that the mural glorified slavery, genocide, and oppression.At Tuesday evening's school board meeting, those in favor of keeping the mural argued the that artist intended to provoke thoughtful discussions about oppression and that the mural could be used as a teaching tool for future generations.Villaluna said the school can find ways to teach these issues without students having to pass by the mural each morning."The students thought this would be good as a lesson but not something we walk by every day," said Villaluna.According to the 2517

Who needs to keep a package of ready to eat macaroni and cheese from spoiling for three years at room temperature? If you're planning a trip to Mars, the answer could be yes. Researchers at Washington State University say they have found a way to triple the lifespan of ready to eat food. In the case of the macaroni and cheese, researchers believe they have found a way to keep macaroni from spoiling for three years. Previously the max lifespan the researchers could get for macaroni and cheese was 12 months using plastic. But using microwave-assisted thermal sterilization and adding a organic coating to metal oxide coating to the plastic can allow food to last three times longer. “We need a better barrier to keep oxygen away from the food and provide longer shelf-life similar to aluminum foil and plastic laminate pouches,” Shyam Sablani, a researcher with WSU, said in a statement. “We’ve always been thinking of developing a product that can go to Mars, but with technology that can also benefit consumers here on Earth.”While using metal oxide coating has been around for sometime, there was a flaw with the coating developing cracks to allow the food to be exposed to oxygen. “We are excited that an over-layer of organic coating on metal oxide helped protect against microscopic cracks,” Sablani said. “Multiple layers of metal oxide coating have also increased the barrier performance. Our research guided development of newer high barrier packaging.”Researchers like Sablani are hopeful the new technology could assist NASA in preserving food for a potential trip to Mars. With current technology, a trip to Mars could last at least two years. A one-way trip to Mars alone could last at least nine months. “NASA knows about our work, but we’re just now getting to the point where we can talk to them with a proven product,” Sablani said. “We hope to work out a way to test these products on the International Space Station in the future to show that the food is safe after long-term storage.”NASA has said its benchmark is for food to last five years. Sablani's team has food that is currently being aged to see if it is possible to store ready to eat meals for five years. Even if the technology might not be used for a trip to Mars, it could be of interest for the military. The packaging could be used for "meals ready to eat or MREs. 2366

US President Donald Trump rallied his supporters in New Mexico on Monday and talked up his chances of turning the state red as part of his efforts to expand his grip on the Electoral College in next year's presidential election."It's been a while since a Republican won New Mexico," Trump told supporters, who greeted him with chants of "USA, USA."''I think we're going to do great here. We're here because we really think we're going to turn this state and make it a Republican state."New Mexico has not voted for a Republican in the presidential election since 2004.Trump captured just 40% of the state vote in 2016, as compared to the 48% that went for Hillary Clinton.She did not visit the state during the 2016 campaign.He also spoke about the US/Mexico border, thanking Mexican President Andrés Manuel López Obrador for "doing a great job for us on the border", which was met by chants of "build that wall" from his supporters.Trump reassured his supporters that the wall was being built, adding that it was difficult to do with the Democrats in control of the House."We'll have almost 500 miles of wall built by the end of next year, and it's making a big difference" he added.Trump also spoke about Supreme Court Justice Brett Kavanaugh, who is facing a new sexual misconduct allegation, accusing the Democrats of using "phony congressional committees," to "demean" and to "libel.""Look at what they're doing today to Justice Kavanaugh," he said, adding,"he's a great man by the way."Trump's rally in Rio Rancho, in suburban Albuquerque, is the first stop on a three-day swing that will also take him to California for fundraisers expected to raise more than million.Trump is looking to find the next Wisconsin or Michigan - states that Democrats generally win in presidential elections but that can surprise under certain conditions, as they did in 2016. 1879
