Lia Is a Disposable Pregnancy Test You Can Flush Down the Toilet

It’s a common Hollywood plot point: A character spots a discarded pregnancy test in a bathroom trash can. Surprise! Someone’s pregnancy is revealed, though they weren’t yet ready to tell anyone (and perhaps never planned on telling them at all). Lia is a new type of disposable pregnancy test designed to be flushed down the toilet to make sure no one ever experiences that kind of privacy violation, according to Glamour.

Lia hasn’t hit the market yet, but when it does, it will be the first major redesign of the home pregnancy test in decades. The first at-home pregnancy test in the U.S. debuted in 1977, and while it took two hours to show a result, it gave women the option to learn their pregnancy status with relative accuracy (it was 97 percent accurate for positive results, but only 80 percent accurate for negative results) for the first time without going to the doctor. In 1988, Unilever came out with the first wand-style pregnancy test—the plastic kind you pee on to reveal the blue stripe indicators. Since then, not much has changed about the basic design of the at-home pregnancy test except the graphics that companies use to convey the test’s results. (The science undergirding the tests has advanced over the years, though.)

Unlike the plastic sticks, Lia is disposable and can be flushed down the toilet or composted. With the shape reminiscent of a sanitary pad, it works similar to the traditional pee-stick test: You urinate on it, then wait for the stripes to appear. While it’s water-resistant enough to withstand the two minutes of pee-soaking required to get a result, the test strip is made of the type of plant fibers that go into toilet paper and will eventually disintegrate in water. It can also be composted: In one experiment, it took 10 weeks to completely degrade in soil.

Like other pregnancy tests available at the drug store, Lia’s results are based on the concentration of human chorionic gonadotropin (a pregnancy hormone) in your pee. It’s FDA approved, and the company reports that it’s more than 99 percent accurate, comparable to other tests on the market.

No matter what the circumstances surrounding a pregnancy are, most people don’t want to share the fact that they could be pregnant with everyone they might share a bathroom with—most people wait several months into their pregnancy to announce the news—and even if they want to tell the world immediately, they probably don’t want to do so via trash can. Lia’s paper design makes it easy to dispose of the test without worrying about who might stumble upon your wastebasket. It’s also more sustainable and won’t clog up landfills like plastic tests. While people don’t use as many pregnancy tests as, say, plastic straws, the over-the-counter plastic pregnancy test market is still a huge one, and a contributor to environmental pollution. As a bonus, the lack of plastic makes Lia cheaper to produce, too.

Lia will eventually be available in stores and online. It’s scheduled to be released sometime in 2018.

How Seiichi Miyake and Tactile Paving Changed the World for Visually Impaired People

More than 140 years after Louis Braille invented the Braille reading system, Seiichi Miyake came up with a different system based on touch that allows visually impaired people to navigate public spaces. Today, tactile paving is used by major cities and transportation services around the world. Miyake was so influential that he's the subject of the Google Doodle for March 18, the 52nd anniversary of tactile paving's debut.

The Japanese inventor designed the influential system with a specific person in mind. His friend was losing his vision, so in 1965, Miyake used his own money to build special mats with raised shapes that lead blind and visually impaired people away from danger and toward safety. Pavement with round bumps was meant to signal nearby danger, such as a street crossing or the edge of a train platform, while a stretch of pavement with straight bars was meant to guide them to safe areas. The tactile design allowed pedestrians to detect the features with canes, guide dogs, or their feet.

Originally called Tenji blocks, the tactile pavement was first installed outside the Okayama School for the Blind in Okayama, Japan in 1967. They quickly spread to larger cities, like Tokyo and Osaka, and within a decade, Miyake's system was mandatory in all Japanese rail stations.

Seiichi Miyake died in 1982 at age 56, but the popularity of his invention has only grown since his death. In the 1990s, the U.S., the UK, and Canada embraced tactile pavement in their cities. Miyake's initial design has been built upon throughout the years; there are now pill-shaped bumps to indicate changes in direction and raised lines running perpendicular to foot traffic to signal upcoming steps. And even though they're often thought of as tools for blind people, the bright colors used in tactile pavement also make them more visible to pedestrians with visual impairments.

Show Houseguests Who's in Charge With This Game of Thrones Doormat

If you’re prone to houseguests who shed crumbs on your sofa and use all the toilet paper without replacing it, it might be time to demand a little respect. This Game of Thrones doormat from the merchants at ThinkGeek offers some guidance. Emblazoned on the mat is an order to “bend the knee” before entering your home.

The 17-inch long by 29-inch wide mat arrives in time for the eighth and final season of the popular HBO series, which is set to debut April 14. Chronicling the lives of disparate characters vying for control of the Iron Throne, the show has often depicted Daenerys Targaryen, also known as the Mother of Dragons and played by Emilia Clarke, ordering subjects to “bend the knee” before addressing her. In season seven, King in the North Jon Snow famously refused to do so before eventually capitulating. Had she laid out the doormat, it’s possible he wouldn’t have taken as long.

The mat retails for $24.99 and can be purchased online here.
