Roughly a dozen individuals on the terror watchlist were encountered by federal officials at the US southern border from October 2017 to October 2018, according to an administration official familiar with data from Customs and Border Protection.The number of individuals encountered at the southern border is a very small percentage of the total known or suspected terrorists who tried to enter or travel to the US in fiscal year 2017. That much larger number has been touted by the administration as it seeks to gain support to build a wall on the border.The official adds there are not significant numbers of known or suspected terrorists crossing the southern border but the number went from "zero to a small increase" over the last couple of years.But the official said that while the number of potential terrorists trying to cross the border is minimal, the Department of Homeland Security is concerned that terrorists could try to exploit immigration patterns.A State Department report for the year 2016 said, "There are no known international terrorist organizations operating in Mexico, no evidence that any terrorist group has targeted U.S. citizens in Mexican territory, and no credible information that any member of a terrorist group has traveled through Mexico to gain access to the United States."Of the approximately dozen individuals, around half were prevented from entering the country at a legal port of entry on the southern border and the other half were apprehended crossing the border illegally between ports of entry. The official did not provide details of whether any of the individuals are currently in US custody. The official noted that just because someone is believed to have a tertiary affiliation doesn't mean there is a prosecutable crime for the Department of Justice to pursue, but it's enough to make sure the individual doesn't make it into the US and for the US to pursue repatriation.DHS has said -- and reiterated in a fact sheet released Monday night -- that 3,755 known or suspected terrorists tried to enter or travel to the US in fiscal year 2017. But those numbers are for all entry points and visa applications around the world, not just at the southern border.CNN has reported that the number is misleading when provided in the context of the southern border, as it primarily reflects individuals who were blocked from entering the US when they applied for visas or sought to travel to the US, including by air.Both the official and DHS also distinguish between individuals on the terror watchlist and what the department calls "special interest aliens," who come from hostile countries or ones with terrorist activity and take irregular routes to the southern border.Nielsen said some 3,000 "special interest aliens" came to the southern border last year. 2847

Smoking even one cigarette a day during pregnancy can double the chance of sudden unexpected death for your baby, according to a new study analyzing over 20 million births, including over 19,000 unexpected infant deaths.The study, published Monday in the journal Pediatrics, analyzed data on smoking during pregnancy from the US Centers for Disease Control and Prevention's birth/infant death data set between 2007 and 2011 and found that the risk of death rises by .07 for each additional cigarette smoked, up to 20 a day, a typical pack of cigarettes.By the time you smoke a pack a day, the study found, your baby's risk of unexpected sudden death has nearly tripled compared with infants of nonsmokers."One of the most compelling and most important points that I would take away from the study is that even smoking one or two cigarettes still had an effect on sudden infant death," said pulmonologist Dr. Cedric "Jamie" Rutland, a national spokesman for the American Lung Association."Every cigarette counts," said lead study author Tatiana Anderson, a neuroscientist at the Seattle Children's Research Institute. "And doctors should be having these conversations with their patients and saying, 'Look, you should quit. That's your best odds for decreasing sudden infant death. But if you can't, every cigarette that you can reduce does help.' "SIDS and SUIDSudden infant death syndrome, known as SIDS, was a frightening, unexplained phenomenon for parents for decades until research discovered a connection between a baby's sleeping position and the sudden deaths. If babies between 1 month and 1 year of age were put to sleep on their stomachs, the risk of dying of SIDS doubled, according to the American Academy of Pediatrics.The introduction of the "back to sleep" campaign in 1994 educated parents about the dangers, and the rate of deaths dropped by about 50% when parents began putting babies to sleep on their backs. That was soon followed by recommendations to remove bumpers, blankets, toys and other potentially suffocating clutter from the crib.By 2010, the rates of SIDS in the United States had fallen to about 2,000 a year, compared with nearly 4,700 in 1993, the American Academy of Pediatrics says.But while the numbers of babies dying of SIDS decreased, two other types of sudden infant death -- ill-defined causes and accidental suffocation -- have risen over the past two decades, Anderson said, bringing total deaths to approximately 3,700 a year.Today, researchers combine the three types of death and call it SUID, short for sudden unexpected infant death.The link to smokingResearch has shown a direct link between mother's smoking and SUID.

SACRAMENTO, Cali. – If you’ve ever wanted to experience life beyond the Earth’s atmosphere, you may get the chance in six years. A company has a goal to make space vacations a reality by 2025. Right now, The Gateway Foundation is developing the very first space hotel with artificial gravity. “So the Von Braun Space Station is going to be the first commercial space station with artificial gravity,” said Tim Alatorre, a senior design architect with the company. The Von Braun Rotating Space Station will basically be a space hotel for customers.“So, the station works like a bike tire, we’re going to have spokes coming out of the central hub. That’s where the spaceships will dock, zero gravity and then it rotates,” said Alatorre. “So, the rotation creates that artificial gravity on the perimeter – this is where people will be living on the outside edge.”Although artificial gravity sounds like something out of science fiction, Alatorre says the science is sound. Designers will be using technology from the International Space Station.“NASA built the space station with just a few tools, one of them is the mechanical arm that we often see in the videos,” said John Blinko, President of the Gateway Foundation. “It’s the arm that we want to adopt in our space construction and designs and schemes and so forth.”But all of this depends on Elon Musk and SpaceX’s launch system. “SpaceX is developing the Super Heavy and the Starship platform. Our projections are showing the price of tickets is going to get lower as time goes on. So for right now, it could be cost prohibitive for some, but in a few short years, it’s going to be a common thing people do. As soon as Starship is ready to launch and is orbital, we want to be one of the first customers to launch into orbit.”In 2025, Alatorre says people will be able to vacation to space. “So, the space station is going to be a big draw to people,” said Alatorre. “We’re going to have a hotel, restaurant, bar, gymnasium.”But it’s more than that. The foundation says it’s the first step to advancing beyond the atmosphere.“But big picture – we’re trying to build out a space industry,” said Alatorre. “We want to have multiple stations in space – space tourism going to the moon, going to Mars, going to other space stations. And just from a humanity standpoint, having hundreds of people being able to go up to space and look back on Earth and just know we are sharing this little blue marble. I think it’s going to have a profound impact on people.” 2522

  

Rescuers pulled people to safety and ferried them through fast-moving floodwaters in middle Oklahoma on Tuesday morning after severe storms swamped the area — and more severe weather will threaten a large portion of the central US as the day goes on.Floodwater closed parts of Interstate 40 in Oklahoma's Canadian County, just west of Oklahoma City, after storms hit late Monday and early Tuesday.In that county, high water was lapping up against homes in a rural area near the community of El Reno on Tuesday morning, and fire departments' swift water rescue teams were using boats to take residents to drier land.Also in the area, video from 656
