Glow-in-the-Dark Paths Come to Singapore

Glow-in-the-dark materials are no longer for toys. Photoluminescence can help cities feel safer at night, whether it’s part of a mural, a bike lane, or a highway. Glow-in-the-dark paths have been tested in several European cities (the above is a Van Gogh-inspired bike path by the Dutch artist Daan Roosegaarde) and in Texas, but now, the technology may be coming to Singapore. The city-state is currently developing a 15-mile greenway called the Rail Corridor, and it now has a glow-in-the-dark path, as Mashable reports.

The 328-foot stretch of glowing path is part of a test of multiple surface materials that might eventually be used throughout the park, depending on public opinion. In addition to the strontium aluminate-beaded path that glows at night, there are also three other 328-foot stretches of the path that are paved with fine gravel, cement aggregate, and part-grass/part-gravel. The glow-in-the-dark material embedded in the walkway absorbs UV light from the sun during the day and can emit light for up to eight hours once the sun goes down.

However, in practice, glow-in-the-dark paths can be less dazzling than they seem. Mashable’s reporter called the glowing effect on Singapore’s path “disappointingly feeble.” In 2014, a glowing highway-markings pilot by Studio Roosegaarde in the Netherlands revealed that the first road markings faded after exposure to heavy rains. When it comes to glowing roads, the renderings tend to look better than the actual result, and there are still kinks to work out. (The studio worked the issue out eventually.) While a person walking or biking down Singapore’s glowing path might be able to tell that they were staying on the path better than if they were fumbling along dark pavement, it’s not the equivalent of a streetlight, for sure.

The trial paths opened to the public on July 12. The government is still gathering survey responses on people’s reactions to the different surfaces to determine how to proceed with the rest of the development. If the glow-in-the-dark path proves popular with visitors, the material could eventually spread to all the paths throughout the Rail Corridor. You can see what the glowing path looks like in action in the video below from The Straits Times.

The New iPhone 11 Is Triggering People With Trypophobia

People with trypophobia, or a fear of clusters of small holes, know which triggers to avoid. Soap bubbles, lotus seed pods, and the insides of cantaloupes can all induce panic and revulsion in people who are sensitive to the pattern. Now, they have a new item to add to their list. As Gizmodo points out, the new iPhone has a design feature that's turning off trypophobes.

Apple debuted the iPhone 11 at an event on September 10 ahead of its release on September 20. This latest model comes with many upgrades, including a super-powered processor and longer battery life, but the biggest change has been met with a mixed reception.

The iPhone 11 Pro has three camera lenses where there would normally be one. People who prefer Apple's sleek, minimalist style have criticized the design, while those with trypophobia have had even stronger reactions. Some scientists think the fear of clusters of holes originally developed as a survival mechanism to steer people away from infectious diseases. When someone gets nauseous at the sight of three cameras grouped on the back of a smart phone, it's because it reminds them of decaying flesh.

The iPhone likely looks the way it does today thanks to another highly specific fear that afflicted Steve Jobs. The Apple founder suffered from koumpounophobia, or a fear of buttons—an incredibly rare phobia that's only been documented once in all of psychiatric literature. His fear may have lead to the popularization of the smooth, buttonless touch screen. It also explains why the tech giant preferred black turtlenecks to button-down shirts.

Though similar to trypophobia, a fear of buttons and fear of clusters of circles aren't quite the same thing. So while triggering to many, the updated iPhone doesn't necessarily conflict with Jobs's original design aesthetic.

The Reason Why Ships Are Often Painted Red on the Bottom

If you’ve ever salvaged a sea vessel, you might have noticed that ship hulls are often red. If you haven’t dealt with a shipwreck—and chances are you haven’t—you may have still seen a red hull in pictures or in partial view at a shipyard. Since that portion of the ship is below the waterline, it seems strange to opt for a specific color.

The reason is tradition. And worms.

In a piece for Jalopnik, Andrew P. Collins explains that early sailing ships protected themselves against barnacles and wood-eating worms by covering their hulls in a copper or copper oxide paint that acted as a biocide. The copper gave the paint a red tint. By reducing the muck that naturally collects on the hull, ships can maintain their structural integrity and avoid being weighed down by gunk like seaweed that would reduce drag.

These days, biocides can be mixed with virtually any color of paint. But the hulls are often painted red to maintain a nautical tradition. Collins also points out that the red may help observers gauge the load of a ship’s cargo. The more weight on board, the lower in the water it will be. That's why you often see numbers positioned vertically on the side of the hull.

No matter what’s covering the hull, it’s never going to completely eliminate growth. Often, ports will prohibit ship owners from scraping hulls while docked, since ships traveling in outside waters might have picked up a non-native species of weed that could prove problematic in a new environment.
