Hundreds of people living in northern Syria near the Turkish border are fleeing, herding their loved ones and running from an unknown fate as fires blaze behind them.These people are members of an ethnic minority known as the Kurdish people.Living in a region controlled by the Kurdish People's Protection Units (YPG), a defense force mostly made up of Kurds, the frequently targeted group is once again under attack.Wednesday, Turkey launched an 459

Four physicians -- experts in pediatrics, infectious diseases and health policy -- have a message for White House Press Secretary Sarah Sanders: Contrary to what she says, it's not clear that the federal government is doing everything it can to care for children crossing the border.And they'd like to help her understand what the government could do better so more children don't die.When asked Friday about the recent deaths of two migrant children in US custody, Sanders told reporters that it was "an absolutely tragic situation" and that "we are doing everything in our capacity to make sure that when people do come, that they're taken care of so we don't have these types of instances."But the physicians say there are steps the government needs to take before Sanders can truthfully say officials are doing "everything in our capacity" to make sure children don't die."In her mind, she may think they're doing everything possible, but we can tell you, you're not doing everything," said Dr. Colleen Kraft, president of the American Academy of Pediatrics. "Look at the facts. The record shows us that more needs to be done."Dr. Buddy Creech, a pediatric infectious disease specialist, said authorities need to do thorough reviews of the children's deaths before declaring that everything possible is being done to prevent more deaths."In hospitals, when someone has a tragic event, a near miss, a drug error, we don't lead with 'we're doing everything we can.' It's ideal to lead with 'let's make ourselves open to self-criticism to make sure that we're taking care of the people who come to us for help,' " said Creech, associate professor of pediatrics at Vanderbilt University Medical Center."The real tragedy would be to say we're doing everything we can when we're not," he added.Internal reviews of the children's deaths are being conducted within the US Department of Homeland Security.Here are three things the physicians say the government could be doing better.Triage children more effectivelyOver the past several years, the United States has seen a large influx of children coming across the border.Before about 2013, about 90% of migrants apprehended at the border were adult men. In contrast, last month, 59% of apprehended migrants were families or unaccompanied minors, according to the Department of Homeland Security.That means about 1,400 to 1,500 unaccompanied minors or family members are apprehended every day, according to the agency."This has created enormous strain on our resources as we tackle the issue of how to deal with large numbers of kids," said Andrew Meehan, US Customs and Border Protection's assistant commissioner for public affairs.There's also been an uptick in the number of apprehended migrants who are ill, Homeland Security officials said at a briefing last week. They said border officers transport dozens of apprehended migrants to hospitals every day."We are doing all we can to handle this flood as humanely and professionally as possible," an official said.Homeland Security Secretary Kirstjen Nielsen has asked the US Centers for Disease Control and Prevention to look into the causes of the migrants' illnesses. She also said that children will receive a "more thorough hands-on assessment" as soon as possible after they're apprehended and that the US Department of Defense has been asked to provide additional medical professionals.Taking care of children -- especially such a large number of children -- requires special training and expertise, said Kraft, president of the pediatricians' group."Children are not just little adults; they have a whole physiology all their own," Kraft said.For example, she points out that children, much more than adults, can look fine but actually be quite ill."A child can be running around and playing while their little systems are breaking down," she said. "When they triage these children and they don't have that pediatric oversight and expertise, they're going to miss kids who don't look like they're ill when they really are."Kraft said she was pleased that on Wednesday, Customs and Border Protection Commissioner Kevin McAleenan reached out to her to ask whether the American Academy of Pediatrics could become involved in giving 4249

FULLERTON, Calif. – Graduating from college is a big deal, but it's an even bigger deal for Jack Rico. At just 13 years old, Rico has become the youngest graduate of Fullerton College in California. The teen has now racked up four associate's degrees and he’s not stopping there. Next, Rico is headed to the University of Nevada on a full-ride scholarship to get a bachelor of science degree in history. So, what does he want to do with all his degrees?"Well I mean, I’m 13, so I don't want to rush everything,” 524

  

For the first time, an object in our solar system has been found more than 100 times farther than Earth is from the sun.The International Astronomical Union's Minor Planet Center announced the discovery Monday, calling the object 2018 VG18. But the researchers who found it are calling it "Farout."They believe the spherical object is a dwarf planet more than 310 miles in diameter, with a pinkish hue. That color has been associated with objects that are rich in ice, and given its distance from the sun, that isn't hard to believe. Its slow orbit probably takes more than 1,000 years to make one trip around the sun, the researchers said.The distance between the Earth and the sun is an AU, or astronomical unit -- the equivalent of about 93 million miles. Farout is 120 AU from the sun. Eris, the next most distant object known, is 96 AU from the sun. For reference, Pluto is 34 AU away.The object was found by the Carnegie Institution for Science's Scott S. Sheppard, the University of Hawaii's David Tholen and Northern Arizona University's Chad Trujillo -- and it's not their first discovery.The team has been searching for a super-Earth-size planet on the edge of our solar system, known as Planet Nine or Planet X, since 2014. They first suggested the existence of this possible planet in 2014 after finding "Biden" at 84 AU. Along the way, they have discovered more distant solar system objects suggesting that the gravity of something massive is influencing their orbit.Farout was found using the Japanese Subaru 8-meter telescope on Hawaii's Mauna Kea in November. Follow-up observations with Carnegie's Las Campanas Observatory's Magellan telescope in Chile determined its path, brightness and color."This discovery is truly an international achievement in research using telescopes located in Hawaii and Chile, operated by Japan, as well as by a consortium of research institutions and universities in the United States," Trujillo said in a statement. "With new wide-field digital cameras on some of the world's largest telescopes, we are finally exploring our Solar System's fringes, far beyond Pluto."In October, the team announced the discovery of "the Goblin" at 80 AU; it's so named because the distant solar system object was first spotted near Halloween.It's unlikely that these objects are influenced by the gravity of gas giants Neptune and Uranus because they never get close enough to them -- which indicates that something else is determining their orbits.Farout's orbit is yet to be determined."2018 VG18 is much more distant and slower moving than any other observed Solar System object, so it will take a few years to fully determine its orbit," Sheppard said in a statement. "But it was found in a similar location on the sky to the other known extreme Solar System objects, suggesting it might have the same type of orbit that most of them do. The orbital similarities shown by many of the known small, distant Solar System bodies was the catalyst for our original assertion that there is a distant, massive planet at several hundred AU shepherding these smaller objects." 3114
