Passengers might be allowed to keep liquids and laptops in their carry-on bags at airport security checkpoints in the United States if screening technology being tested at select airports is widely adopted.The Transportation Security Administration announced plans Monday to test computed tomography (CT) scanners for carry-on bags, with up to 40 units expected to be in place at US airports by the end of 2018.The X-ray scanning equipment creates 3D images that can be analyzed on three axes for explosives and other threats. The CT technology is similar to that used for medical imaging. Current screening machines for carry-on bags generate 2D images."Use of CT technology substantially improves TSA's threat detection capability at the checkpoint," said TSA Administrator David Pekoske in a statement.CT technology testing started in 2017 at Phoenix Sky Harbor International Airport and Boston's Logan International Airport. John F. Kennedy International Airport has also received a scanner.London's Heathrow is among international airports testing the 3D technology.An initial 15 units will be deployed within the next few months at the following US airports:Baltimore-Washington International Airport (BWI)Chicago O'Hare International Airport (ORD)Cincinnati/Northern Kentucky International Airport (CVG)Houston Hobby Airport (HOU)Indianapolis International Airport (IND)John F. Kennedy International Airport (JFK)Boston Logan International Airport (BOS)Los Angeles International Airport (LAX)McCarran International Airport (LAS)Oakland International Airport (OAK)Philadelphia International Airport (PHL)Phoenix Sky Harbor International Airport (PHX)San Diego International Airport (SAN)St. Louis Lambert International Airport (STL)Washington-Dulles International Airport (IAD) 1801

Outside of the race for president, the 2020 Election was historic.It was the first time that Republican stronghold states voted in favor of marijuana, as both South Dakota and Montana voted to legalize recreational use of the drug.Arizona, a more moderate state, along with progressive New Jersey, also voted to legalize recreational use during the 2020 Election.“Once people legalize it they like it. They like prohibition ending,” said Brendan Johnson, a former U.S. Attorney for the district of South Dakota.In South Dakota, the vote to legalize marijuana on Nov. 3 passed with 54.2 percent approval, while 62 percent voted to re-elect Donald Trump as president; a once-partisan discrepancy that could also be seen in Montana, where 56.9 percent of the electorate voted for Trump and 57.8 voted for legalization.“Part of our state’s libertarian streak, which leads people to believe that the government doesn’t have a role to play in this, and, frankly, prohibition carried the day along with economic costs of building larger and larger prisons across the state,” said Johnson.According to Johnson, 10 percent of South Dakota’s arrests last year were for marijuana possession, oftentimes only a few grams. He says it is a number that is seen in states countrywide and one that has swayed Republicans to vote for a bill that they once may have not.In 1992, only about 25 percent of the party supported legalization nationwide, where today, that number stands at 53 percent, according to the Justice Collaborative Institute.“It became very hard to point towards legalization and say there was anything that was moving the topline numbers,” said Andrew Freedman, a vice president for Forbes-Tate, a bipartisan public advocacy firm.Freedman helped implement Colorado’s marijuana laws when the state became the first to legalize recreational marijuana in 2014. He says it became a case study for others who thought the drug would lead to more arrests, youth use, and crime-- all things that never transpired, according to the Crime and Justice Research Alliance.“There are a lot of Republicans who believe in less government and who think that the war on drugs was a failure and would themselves, be for legalization,” said Freedman. “There were a lot of unanswered questions, and now more and more questions are getting answered so there are fewer and fewer reasons to say no.”In six years, 15 states have voted to legalize recreational pot while 35 have legalized medical use. 2485

PAHOA, Hawaii (AP) — Lava creeping across roadways destroyed four homes and left dozens of others in the shadow of Hawaii's Kilauea volcano isolated Saturday, forcing more residents to plan for a possible evacuation.Hawaii County Civil Defense said a fissure near the neighborhood of Lanipuna Gardens has been continuously erupting, releasing a slow-moving lava flow. If that lava threatens a nearby highway, more people will be told to prepare for voluntary evacuation.On Friday, fast-moving lava crossed a road and isolated about 40 homes in a rural subdivision, forcing at least four people to be evacuated by county and National Guard helicopters.RELATED: San Diegans working with Red Cross in HawaiiPolice, firefighters and National Guard troops were securing the area of the Big Island and stopping people from entering, Hawaii County Civil Defense reported. The homes were isolated in the area east of Lanipuna Gardens and Leilani Estates. Both neighborhoods had 40 structures, including 26 homes, decimated by lava over the past two weeks.Officials said three people were still in that area but not in imminent danger. They were advised to shelter in place and await rescue by helicopter first thing Saturday.County officials have been encouraging residents in the district to prepare for potential evacuations.RELATED: Golfers continue playing as ash cloud grows in HawaiiEdwin Montoya, who lives with his daughter on her farm near the site where lava crossed the road and cut off access, said he was at the property earlier in the day to get valuables."I think I'm lucky because we went there this morning and we got all the batteries out, and all the solar panels out, about ,000 worth of equipment," he said. "They have to evacuate the people that are trapped up there right now in the same place that we were taking pictures this morning."He said no one was on his property, but his neighbor had someone on his land."I know that the farm right next to my farm . he's got somebody there taking care of the premises, I know he's trapped," Montoya said.Montoya said the fissure that poured lava across the road opened and grew quickly."It was just a little crack in the ground, with a little lava coming out," he said. "Now it's a big crater that opened up where the small little crack in the ground was."Experts are uncertain about when the volcano will calm down.The Big Island volcano released a small explosion at its summit just before midnight Saturday, sending an ash cloud 10,000 feet (3,048 meters) into the sky. The U.S. Geological Survey's Hawaiian Volcano Observatory said eruptions that create even minor amounts of ashfall could occur at any time.This follows the more explosive eruption Thursday, which emitted ash and rocks thousands of feet into the sky. No one was injured and there were no reports of damaged property.Scientists said the eruption was the most powerful in recent days, though it probably lasted only a few minutes.It came two weeks after the volcano began sending lava flows into neighborhoods 25 miles (40 kilometers) to the east of the summit.A new lava vent — the 22nd such fissure — was reported Friday by county civil defense officials.Several open fissure vents are still producing lava splatter and flow in evacuated areas. Gas is also pouring from the vents, cloaking homes and trees in smoke.The fresher, hotter magma will allow faster lava flows that can potentially cover more area, said Janet Babb, a geologist with the Hawaiian Volcano Observatory.Much of the lava that has emerged so far may have been underground for decades, perhaps since a 1955 eruption.Meanwhile, more explosive eruptions from the summit are possible."We have no way of knowing whether this is really the beginning or toward the end of this eruption," said Tom Shea, a volcanologist at the University of Hawaii. "We're kind of all right now in this world of uncertainty."It's nearly impossible to determine when a volcano will stop erupting, "because the processes driving that fall below the surface and we can't see them." said volcanologist Janine Krippner of Concord University in West Virginia.U.S. government scientists, however, are trying to pin down those signals "so we have a little better warning," said Wendy Stovall, a volcanologist with the observatory.Thus far, Krippner noted, authorities have been able to forecast volcanic activity early enough to usher people to safety.The greatest ongoing hazard stems from the lava flows and the hot, toxic gases spewing from open fissure vents close to homes and critical infrastructure, said Charles Mandeville of the U.S. Geological Survey's volcano hazards program.Authorities have been measuring gases, including sulfur dioxide, rising in little puffs from open vents.The area affected by lava and ash is small compared to the Big Island, which is about 4,000 square miles. Most of the island and the rest of the Hawaiian chain is unaffected by the volcanic activity on Kilauea.State and local officials have been reminding tourists that flights in and out of the entire state, including the Big Island, have not been impacted. Even on the Big Island, most tourist activities are still available and businesses are open.___Associated Press journalists Jae Hong and Marco Garcia in Pahoa, Sophia Yan, Jennifer Kelleher and Audrey McAvoy in Honolulu, Becky Bohrer in Juneau, Alaska, Seth Borenstein in Washington, D.C., and Alina Hartounian in Phoenix contributed to this report. 5478

  

PINE VALLEY (KGTV) -  Nineteen people are in custody after the horse trailer they were traveling in crashed Saturday on Interstate 8, about 55 miles east of San Diego, Border Patrol said.The trailer, which was being pulled by a Ford F250 pickup truck, separated from the truck and overturned on its right side just before noon, according to the California Highway Patrol. Border Patrol agents said that the trailer was smuggling people into the country and all of the apprehended people identified as Mexican nationals. The driver of the truck managed to escape, according to Border Patrol.Six people were injured in the crash and two of them had to be airlifted to a hospital for treatment, Border Patrol told 10News.Witnesses said people ran out of the overturned horse trailer. Border Patrol agents took 19 people into custody and continued to look for others that may have fled on foot.   935

  

Over the past year, Amazon has opened seven of its Amazon Go stores to the public, ditching checkout lines for AI that tracks what customers want to buy. Now, the retailer is taking its cashier-free shops in a new, smaller direction.On Wednesday, Amazon opened its first pint-sized Amazon Go store, which takes up about 450 square feet inside one of its Seattle offices — a fraction of other Amazon Go locations, which range from 1,800 to 2,000 square feet.Amazon Go Vice President Gianna Puerini, who gave CNN Business a look around the store early this week, said the idea is to eventually bring them to places like office building lobbies and hospitals. Similar to the full-size stores, she said, they could go "anywhere where there's a lot of people who are hungry and in a rush."Puerini wouldn't say when others will open, though she said she hopes they will crop up "soon." Such small stores could also help Amazon keep ahead of a handful of startups who are trying to convince existing retailers to buy their cashierless technology.Unlike other Amazon Go stores — seven are open and two others are under construction — this one is not available to the general public. Only Amazon employees and guests can visit the store. The retailer took the same approach with its first Amazon Go store, which initially opened in 2016 just to employees. It's "just easier for us to experiment closer to home," Puerini said.When CNN Business visited the new, small Amazon Go store, it was still hidden behind plywood and a black curtain. It looked very much like a regular Amazon Go store, but plopped in the middle of a common area in an Amazon office in downtown Seattle, right next to an employee café. (The office itself is above a much more traditional Macy's store.) This version of Amazon Go had just a few aisles, with shelves stocked full of cut fruit from Amazon-owned Whole Foods, yogurts, chocolate bars and more.Though it's much smaller than the existing stand-alone Amazon Go stores, the technology behind this store is the same: after downloading an Amazon Go app, you scan an in-app code on an entry gate to get inside. Then a series of cameras above you work in concert with weight sensors on shelves and software to track the items you pick up and put down. As at all other Amazon Go stores, you walk out when you're done shopping, and the app emails you an itemized receipt.The small stores could also allow Amazon to roll out more cashier-free locations faster than it could by simply opening stand-alone Amazon Go stores. The small stores are modular, Puerini said, and take only weeks to put together. That's much faster than it takes to open up a free-standing Amazon Go store, which the company said typically takes months.The tiny shops could also be used to bring Amazon Go to a range of new markets, such as airports, which Amazon is reportedly considering for the AI-checkout stores. Puerini wouldn't confirm or deny whether Amazon is looking into opening Amazon Go stores of any size in airports, but said that, with many hungry people hurrying around, airports fit her "simple criteria" for the stores.As with other Amazon Go stores, however, these won't be entirely self-sustaining. An employee will be needed to stock shelves when food arrives or clean up if a shopper, say, drops a glass Frappuccino bottle on the floor. The small, in-office location in Seattle will have set hours (it will be open from 7 am to 6 pm, Monday through Friday), and it will be staffed during that time, as the current Amazon Go stores are."People do still want help. They like to ask the associates, 'What's your favorite? What should I get?' Or they might want to make sure about ingredients on something," Puerini said. "There's still a lot of human interaction." 3778
