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.

Jeff Bezos Is Helping to Build a Clock Meant to Keep Time for 10,000 Years

Few human inventions are meant to last hundreds of years, much less thousands. But the 10,000 Year Clock is designed to keep accurate time for millennia. First proposed in 1989, the long-lasting timepiece is finally being installed inside a mountain in western Texas, according to CNET.

The organization building the clock, the Long Now Foundation, wanted to create a tribute to thinking about the future. Founded by computer scientist Danny Hillis and Whole Earth Catalog publisher Stewart Brand, the group boasts famous members like musician Brian Eno and numerous Silicon Valley heavyweights. Amazon founder Jeff Bezos is putting up the $42 million necessary to complete the project, writing that “it's a special Clock, designed to be a symbol, an icon for long-term thinking."

Measuring 500 feet tall when it's completed, the clock will run on thermal power and synchronize each day at solar noon. Every day, a “chime generator” will come up with a different sequence of rings, never repeating a sequence day to day. On specific anniversaries—one year, 10 years, 100 years, 1000 years, 10,000 years—it will animate a mechanical system within one of five rooms carved into the mountain. On the first anniversary, for instance, the clock will animate an orrery, a model of the solar system. Since they don’t expect to be alive for many of the future anniversaries, the clock’s creators won't determine animations for 100, 1000, or 10,000 years—that'll be left up to future generations. (To give you an idea of just how far away 10,000 years is, in 8000 B.C.E., humans had just started to domesticate cows for the first time.)

Though you can sign up to be notified when the clock is finished, it won’t be easy to see it up close. The nearest airport is several hours’ drive away, and the mountain is 2000 feet above the valley floor. So you may have to be content with seeing it virtually in the video below.

Barbie Is Now Giving Coding Lessons

Mattel wants to help 10 million kids learn to code by 2020, and the toy giant is enlisting one of its most career-focused assets: Barbie. According to Engadget, Mattel is working with the coding education company Tynker to make seven Barbie-themed computer programming lessons.

Barbie has been a pilot, an architect, the president, and a computer engineer, so there may be no better character to teach kids the joys of coding. The lessons, arriving in summer 2018, will be designed for youngsters in kindergarten and up, and will teach Barbie-lovers more than just how to make apps. They’ll use Barbie’s many careers—which also included veterinarian, robotics engineer, and astronaut—as a way to guide kids through programming concepts.

An illustration depicts Barbie and her friends surrounded by cats and dogs and reads 'Barbie: Pet Vet.'

There are plenty of new initiatives that aim to teach kids how to code, from a Fisher-Price caterpillar toy to online games featuring Rey from Star Wars. This is the third partnership between Mattel and Tynker, who have already produced programming lessons using Hot Wheels and Monster High.

Kindergarten may seem a little soon to set kids on a career path as a computer programmer, but coding has been called “the most important job skill of the future,” and you don’t need to work for Google or Facebook to make learning it worthwhile. Coding can give you a leg up in applying for jobs in healthcare, finance, and other careers outside of Silicon Valley. More importantly for kids, coding games are fun. Who wouldn’t want to play Robotics Engineer Barbie?
