New Device Sanitizes Escalator Handrails While They're in Use

If you have ever hesitated to touch a well-used escalator's handrails for fear of contracting some disease from the masses, LG Innotek has an answer for you. The company just released a handrail sterilizer that uses UV light to kill nearly every germ coating the rubber belts, according to The Verge.

As the railings move with the escalator, they pass through the UV light, which kills 99.99 percent of germs, according to tech developer LG Innotek. The sterilizer is placed just before escalator users hop on, ensuring the handrails are still relatively clean when you grab on at the bottom. The device is a little bigger than a regular hand sanitizer dispenser (around the size of a piece of paper) and starts automatically when the escalator begins moving. It runs on power generated by the movement of the escalator.

UV radiation is used to kill super-germs in hospitals (and one company wants to bring it to planes), but it's relatively easy to use on your phone, your toothbrush, or anywhere else in your house. You can already get handheld UV sterilizers online, as well as aquarium-specific ones. In April 2017, LG Innotek released a faucet that purifies water by UV-sterilizing it inside the aerator. However, the fact that escalator railings are constantly on the move makes them easier to clean automatically than subway railings, door handles, and other potentially germy public surfaces we touch every day.

Bear in mind that while nobody likes getting a cold, germs aren't always bad for you. Some types can even help protect you against developing asthma, as scientists found while researching the health differences between Amish children and their counterparts on more industrialized farms. Whether you touch the handrails or not, cities have their own unique microbiomes, and those ubiquitous bacteria are pretty much guaranteed to get on you whether you like it or not. On the bright side, if you are a germophobe, UV sterilization has been touted as a possible alternative to other antibacterial treatments that cause supergerms.

The FCC's New Scam Glossary Will Help You Identify Fraudulent Calls

The Federal Communications Commission (FCC) knows that robocalls have gotten worse in recent years, and it's finally doing something about it. In June 2019, the FCC voted to give phone carriers the freedom to block spam calls without waiting for customers to opt in. The change is a good first step, but it won't end the robocall scourge completely. For the unwanted calls that sneak past your phone's defenses, the FCC also published a scam glossary on its website, Popular Science reports.

The glossary lists some of the most common (as well as some uncommon) strategies used by criminals, giving you an idea of what to be on the lookout for next time you get a suspicious call. The "Health Insurance Scam," for example, involves callers selling fake health care coverage for a cheap price. There's also the "One Ring Scam," where the scammer will hang up quickly after the first ring without giving you time to answer the call. Their goal is to trick you into calling them back and paying for international call fees.

The glossary includes more general terms that relate to phone scams as well. Spoofing is defined as calls made through fake caller IDs that appear trustworthy, either by matching your home area code or that of a legitimate organization. Slamming happens when a phone company moves you from your existing service provider to theirs without your consent.

Familiarizing yourself with popular scams is one of the easiest ways to protect yourself from falling for fraudulent calls. Another way is to install robocall-blocking apps on your phone. Here are some options to check out.

Fish Tube: How the 'Salmon Cannon' Works and Why It's Important

If you’ve been on the internet at any point in the past week, you’ve certainly come across footage of wildlife conservationists stuffing salmon into a giant plastic tube and shuttling them over obstacles. It’s so bizarre—even by the already loose standards of the web—that it briefly ignited discussions over fish welfare, its purpose, and the seeming desire of people to be similarly transported through a pneumatic tunnel into a new life.

Naturally, the “salmon cannon” has a mission beyond amusing the internet. The system was created by Whooshh Innovations, a company that essentially adopted the same kind of transportation system featuring pressurized tubing that's used in banking. Initially, the system was intended to transport fruit over long distances without bruising. At some point, engineers figured they could do the same for fish.

The fish payload is secured at the entrance of the tube—acceptable species can weigh up to 34 pounds—and moves through a smooth, soft plastic tube that conforms to their body shape. Air pressure behind them keeps them moving. The fish are jettisoned between 16 and 26 feet per second to a new location, where they emerge relatively unscathed. Because there’s no need for a water column, the tubing can cover most terrain at virtually any height.

The tubing solution is a human answer to a human problem: dams. With fish largely confined to still bodies of water thanks to dams and facing obstacles swimming upstream to migrate and spawn, fish need some kind of assistance. In the past, “fish ladders” have helped fish move upstream by providing ascending steps they can flop on, but not all fish can navigate such terrain. Another system, trapping and hauling fish like cargo, results in disoriented fish who can even forget how to swim. The Whooshh system, which has been in used in Washington state for at least five years, allows for expedient fish export with an injury rate as little as 3 percent, although study results have varied.

The video features manual insertion of the fish. In the wild, Whooshh counts on fish making semi-voluntary entries into the tubing. Once they swim into an enclosure, they’re curious enough about the tube to go inside.

If all goes well, the system could help salmon be reintroduced to the Upper Columbia River in Washington, where the population has been depleted by dams. Testing of the device there is awaiting approval from the U.S. Army Corps of Engineers.
