Breakthroughs, discoveries, and DIY tips sent every weekday. A Canadian kid is proof that major scientific discoveries don't always have to come from grizzled researchers with fancy equipment. Two years ago, then-8-year-old Lucas Atchison went on a family trip to Point Farms Provincial Park in Ontario. Armed with a metal detector he had just received as a birthday present, Atchison dutifully scanned the area, hoping to hear that coveted "beep." Eagerly digging into the site, Lucas uncovered a metal spike, which his father initially dismissed as something used to tie up boats.

Parents spoke after the Antioch High School shooting on Wednesday, Jan. 22, outside of Nashville, Tennessee. Antioch High School in Nashville, Tennessee, where a deadly shooting took place last Wednesday, did not have metal detectors due to some administrators' concerns about racism, the New York Post reported. "I knew this day was gonna happen," Fran Bush, a former Metro Nashville Public Schools (MNPS) board member, told the New York Post. "I knew it was gonna happen just because it's like a free open door, everybody coming in." The shooting, which left 16-year-old student Josselin Corea Escalante and the suspect dead, has parents calling for the school to bring in metal detectors after the AI security system failed to detect the 17-year-old gunman's weapon.

Parcels delivery is a critical activity in railways. More importantly, each parcel must be thoroughly checked and sorted according to its destination address. We require an efficient and robust IoT system capable of doing all of these tasks with great precision and minimal human interaction. This paper discusses, We created a fully-fledged solution using IoT and machine learning to assist trains in performing this operation efficiently. In this study, we covered the product, which consists mostly of two phases. Scanning is the first step, followed by sorting. During the scanning process, the parcel will be passed through three scanners that will look for explosives, drugs, and any dangerous materials in the parcel and will trash it if any of the tests fail. When the scanning step is over, the parcel moves on to the sorting phase, where we use QR codes to retrieve the details of the parcels and sort them properly. The simulation of the system is done using the blender software. Our research shows that our procedure significantly improves accuracy as well as the assessment of cutting-edge technology and existing techniques.

Have you ever gone to a sporting event and spent what seems like an eternity just trying to get in? Security technologies can slow lines down to a grinding halt, and they're not always effective – your necklace, keys, and belt may set the metal detector off, while weapons can still get through. At the FirstEnergy Stadium in Cleveland, it turns out a lot of football fans wear steel-toed boots. "Everyone who wore these boots were setting off when they were coming in," says Brandon Covert, vice president of information technology for the Cleveland Browns. The team has managed to overcome this problem with artificial intelligence, after adopting security screening technology from the company Evolv.

When Peter George saw news of the racially motivated mass-shooting at the Tops supermarket in Buffalo last weekend, he had a thought he's often had after such tragedies. "Could our system have stopped it?" he said. But I think we could democratize security so that someone planning on hurting people can't easily go into an unsuspecting place." George is chief executive of Evolv Technology, an AI-based system meant to flag weapons, "democratizing security" so that weapons can be kept out of public places without elaborate checkpoints. As U.S. gun violence like the kind seen in Buffalo increases -- firearms sales reached record heights in 2020 and 2021 while the Gun Violence Archive reports 198 mass shootings since January -- Evolv has become increasingly popular, used at schools, stadiums, stores and other gathering spots. To its supporters, the system is a more effective and less obtrusive alternative to the age-old metal detector, making events both safer and more pleasant to attend. To its critics, however, Evolv's effectiveness has hardly been proved. And it opens up a Pandora's box of ethical issues in which convenience is paid for with RoboCop surveillance. "The idea of a kinder, gentler metal detector is a nice solution in theory to these terrible shootings," said Jay Stanley, senior policy analyst for the American Civil Liberties Union's project on speech, privacy, and technology. "But do we really want to create more ways for security to invade our privacy?

What started as a test of a new bag check experience at Disney Springs will now expand to all four Walt Disney World theme parks. In what is a long overdue move, Disney will be moving away from a hands-on approach to bag check screening and moving into the 21st century with Artificial Intelligence screening that will greatly improve the bag check process. As a reminder, the old bag check process would rely on a security Cast Member to search your bag by hand before sending you through a metal detector to check your person. Of course, the level of thoroughness in the bag check varied from security Cast Member to security Cast Member, and introduced the element of human error. As you might imagine, we've been through security hundreds, if not thousands of times over the years, and just like everyone else, we've seen different levels of detail in the bag check searches. After a manual bag check search, security would randomly ask guests to walk through a metal detector, meaning not everyone had to pass through.

We all see the headlines nearly every day. Whether primitive (gunpowder) or cutting-edge (unmanned aerial vehicles) in the wrong hands, technology can empower bad actors and put our society at risk, creating a sense of helplessness and frustration. Current approaches to protecting our public venues are not up to the task, and, frankly appear to meet Einstein's definition of insanity: "doing the same thing over and over and expecting a different result." It is time to look past traditional defense technologies and see if newer approaches can tilt the pendulum back in the defender's favor. Artificial Intelligence (AI) can play a critical role here, helping to identify, classify and promulgate counteractions on potential threats faster than any security personnel.

A number of vendors are seeking to provide next-generation gun detection capabilities to schools and other organizations. Responding to too-frequent reports of shootings in the U.S., technology firms are beginning to roll out systems designed to quickly detect firearms in public settings. Many of the systems offer an advantage over conventional metal detectors, given that they often include video surveillance that can spot a gun in plain sight in a crowd, surveillance a metal detector may not be able to duplicate. Plus, some of the systems can utilize facial recognition to identify known persons of interest, such as known sex offenders, gang members, and the like; another bit of surveillance currently beyond the reach of conventional metal detectors. The Canadian firm Patriot One Technologies, for example, offers a solution featuring a microwave radar scanner driven by artificial intelligence (AI) that can detect hidden weapons, along with a video surveillance component.

Activate satellite view in Google Maps and head to the Las Vegas strip, and you'll see it: a strange smattering of Y-shaped buildings. Their blueprints put gambling at the center of everything, funneling visitors past slot machines and card tables whether they're en route to a show, their room, a restaurant, or a retail shop. For years, the casino floor was where Vegas resorts made most of their money, and the Y was devilishly good at monetizing it. The Westgate Las Vegas Resort and Casino was the first megacasino to feature the design--a bit of trivia that Mark Waltrip, Westgate Resort's chief operating officer, relays with a mixture of pride and irony. Y-shaped buildings have their issues, after all.
