EL PASO, Texas (AP) — As many as 2,000 U.S. inspectors who screen cargo and vehicles at ports of entry along the Mexican border may be reassigned to help handle the surge of Central American families coming across, the Trump administration said Monday.The temporary reassignments, up from the current 750 inspectors, threaten to slow the movement of trucks bringing TVs, medical devices and other goods into the U.S. and cause delays for cross-border commuters who come for work or school.The inspectors are instead being put to work processing migrants, taking their applications for asylum and transporting them to holding centers.Homeland Security Secretary Kirstjen Nielsen said the reassignments are necessary to help manage a huge influx of migrants that is straining the system and overflowing border facilities."The crisis at our border is worsening, and DHS will do everything in its power to end it," Nielsen said.The effects of pulling inspectors from ports of entry were on display in El Paso, where thousands of border crossers lined up Monday, waiting about an hour to cross into the U.S. They included vendors, U.S. citizens and students with visas.Sergio Amaya, 24, a student at the University of Texas-El Paso, is an American citizen who lives in Juarez. He said it normally takes him two minutes to cross the bridge."The Border Patrol agent said it's going to get worse," Amaya said.Meanwhile, business owners and elected officials warned of the economic consequences if President Donald Trump makes good on his threat last week to shut down all ports of entry along the southern border to stem the wave of asylum seekers.The United States and Mexico trade about .7 billion in goods daily, according to the U.S. Chamber of Commerce, which said closing the border would be "an unmitigated economic debacle" that would threaten 5 million American jobs.Laredo Mayor Pete Saenz, chairman of the Texas Border Coalition, said a closure would be catastrophic."Closing the border would cause an immediate depression in border state communities and, depending on the duration, a recession in the rest of the country," he said."Our business would end," Marta Salas, an employee at an El Paso shop near the border crossing that sells plastic flowers that are used on the Mexican side by families holding quincea?eras, the traditional coming-of-age celebrations.Salas said her whole family would be affected if the president closed the border."There are Americans who live there. I have nephews who come to UTEP, to grade school, to high school every day," Salas said.Apprehensions all along the southern border have soared in recent months, with border agents on track to make 100,000 arrests and denials of entry there this month, more than half of them families with children.In addition to reassigning hundreds of inspectors, Nielsen has asked for volunteers from non-immigration agencies within her department and sent a letter to Congress requesting resources and broader authority to deport families faster. The administration is also ramping up efforts to return asylum seekers to Mexico.___Associated Press writers Colleen Long in Washington and Nomaan Merchant in Houston contributed to this story. 3224

During the last few months, many health experts have been talking about reaching “herd immunity” with the distribution of the COVID-19 vaccine. Over the Christmas weekend, Dr. Anthony Fauci said he estimates the country needs to reach 80-85% with the vaccine to attain herd immunity.Here’s what that means.Herd immunity is a concept used in discussions about vaccination, and signifies the threshold needed for a population as a whole to be protected from a virus.The World Health Organization clarifies that herd immunity, or population immunity, “is achieved by protecting people from a virus, not by exposing them to it.”The Mayo Clinic also describes the situation following the 1918 Spanish Flu outbreak. They say people who survived the pandemic were later immune to infection of the H1N1 flu, also referred to as swine flu.Health experts warn that relying on community infection to create herd immunity could be dangerous; there are questions about how long the antibodies created by infection protect against reinfection, and a high level of community infection could lead to overwhelmed medical facilities and a high number of deaths.When the threshold of herd immunity is reached, it means the vast majority of a population is vaccinated and has antibodies, thereby lowering the overall amount of community spread of the virus. It also means portions of the population who cannot get vaccinated are kept safer by the limited spread.What that threshold is varies depending on the virus and the efficacy of the vaccine.According to the WHO, herd immunity against the measles is reached with 95% vaccination, while herd immunity against polio is 80%.Dr. Fauci believes herd immunity for COVID-19 can be reached with around 85% of the population having antibodies. 1778

EL CAJON, Calif. (KGTV) - A plane made an emergency landing Friday on westbound Interstate 8, according to the California Highway Patrol.A 36-year-old student pilot and 25-year-old instructor from California Flight Academy were above El Cajon and had engine trouble about 11:15 a.m., the CHP reported.According to SDSUBaseball's twitter page, the instructor is Ryan Muno, a former Aztec baseball star.Both men were trying to land at Gillespie Field but were forced to touch down on the freeway. The instructor took over the controls and landed safely in lanes near Second Ave."The instructor took over the controls of the plane. He stated he knew they weren’t going to make it to the airport, so his next course of action was to take it down the interstate," Officer Travis Gallows with CHP El Cajon said.Muno able to land the plane on the fast lane on I-8 Westbound, miraculously missing power lines and overhead freeway sign.10News spoke to Jim Andersen, who was driving a few cars behind the plane when it landed. When he passed by, he saw that the two aviators looked shaken up."The two gentlemen were talking to each other. They looked like they were catching their breath because they had just come to a stop," Andersen said.Thankfully it wasn't a crash course, but a valuable lesson on emergency landings. “For them to make that landing, and have nobody else involved in it, it’s pretty much a miracle,” Officer Gallows said. RELATED: Small plane lands on I-15, closing off-ramp / Plane lands on SR-67No cars were hit and no one was injured. The plane, a Piper aircraft based in El Cajon, remained intact.The pilot and instructor pushed the plane to the right shoulder.Officers shut down the Mollison Ave. off-ramp of westbound I-8 due to the plane emergency. WATCH LIVE: CHP Officer Jim Bettencourt said the CHP would be in contact with the National Transportation Safety Board to determine the best way to remove the plane."Try not to stop and slow down," Bettencourt recommended to drivers in the area.CHECK TRAFFIC CONDITIONS  2095

  

Driving down a dirt logging road in rural Maine, paramedic Nathan Yerxa can’t help but take in the view most days. Looking out over the landscape here, it’s as if the sky and the land seem to merge.Yerxa is a paramedic for North East Mobile Health Services and stationed in Jackman, Maine, a small town in the northern part of this state home to about 700 people. From the edge of town, you can see the Canadian border in the distance, and on any given day, paramedics here are responsible for covering an area that’s approximately the size of the state of Rhode Island.“The remote landscape and difficult terrain make it difficult to bring resources to the area,” Yerxa said, as he drove through town in a Ford pickup truck that’s been converted to an all-terrain ambulance.Like rural communities across the country, getting patients to an emergency room in this area is a difficult, often time-consuming task. The closest ER is about 70 miles away, a trip that can sometimes take close to two hours. While Jackman does have a community health center, the facility can’t perform many emergency procedures most larger hospitals can.So, in an effort to save time and lives, the emergency room is being brought to Jackman in an innovative new way, harnessing technology and the expertise of paramedics likes Yerxa.“I think it’s one of those situations where what’s old is new again,” he said.The idea is a Critical Access Integrated Paramedic program. Paramedics here are receiving more training in critical care. While at the same time, that pickup truck Yerxa relies on is being outfitted with tools like satellite internet and a satellite phone. First responders even have heart rate monitors that can send data wirelessly to a doctor anywhere.The concept is simple. Using technology, paramedics can instantly connect to a doctor no matter where they take a call. From stitches to ultrasounds, paramedics in this region are bridging the rural healthcare gap by instantly connecting via video chat to a doctor who may be hours away.“It is in many ways like a high-tech home visit that you might have seen 60 years ago, but we’re also bringing urgent care services with us,” Yerxa explained.Finding new ways for rural communities to connect is a key component to the program's success.Nationwide 25 million people don't have access to broadband.The COVID-19 pandemic has only magnified the issue. In Maine alone, 36,000 telehealth calls were made last month up from 650 the same time last year. Many times, though, patients and doctors have trouble connecting because of poor internet connections.Town manager Victoria Forkus pushed hard for the program.“We were in a way forced to implement this new program early because of COVID,” she said while sitting inside Jackman’s town offices.The whole program is costing Jackman and surrounding communities about 0,000 a year to implement. Some of the money will come from a tax increase, which is no small feat in a town where the median income is just ,000.But out here, the program has overwhelming support.“What’s the dollar amount on one of my neighbors’ lives? What’s the cost of saving a community member? It’s priceless,” Forkus added.The concept of the program is gaining attention across the state.Jim Rogers, with Health Connect Networks based in Maine, is lobbying Congress hard to expand rural broadband connectivity. It’s something he says is now more imperative than ever given the pandemic.“People in these rural communities just don’t have adequate internet to support a telehealth consult,” he said.As for Yerxa, he sees the program as something other rural communities across the country can emulate.“Hopefully, we can now provide 24-hour coverage to patients in any of these rural locations.” 3770

  

DNA researchers are making a big prediction. In just a few years, they'll have enough DNA samples to match every person in the country. That's even if you've never taken one of those ancestry DNA tests.This is all thanks to those ancestry test kits. If someone’s relative takes the test, enough information is provided for scientists to link to you."Yes, eventually everyone's going to be traceable through DNA," says Itsik Pe’er, an associate professor at Columbia University.It also means solving crimes could get a lot easier.  Police have already started taking DNA from unknown suspects and comparing it to DNA databases.That information can lead to a match to a suspect’s relative."People want to connect to their long-lost second, third, fourth cousins and find those matches,” says Pe’er. “The flip side of that is that, yeah, investigators can find those matches due to DNA that have been sitting in these warehouses for decades."Pe'er is the co-author of a study at Columbia University that says scientists only need a 2 percent sample from the roughly 326 million people in the United States to be able to match anyone's DNA.Privacy experts worry that even people who have never committed a crime might not want to be matched to relatives.But it's a fact of science as the DNA sample continues to grow."It's just still incredible to think about, you know, like we live in such a big world, but it's really, really small," Pe’er says.Private companies are working to protect their databases, including places like My Heritage and 23andMe that prohibit forensic use of their databases in their user agreements. 1632
