Foldable bikes have been around for some time, but Sada Bycicle pushes the limits of space-saving design by folding to the size of an umbrella. This hubless bike features a frame that folds away for maximum portability – it can even be packed in a regular-sized backpack!

The Sada Bike has a standard bicycle dimension with 26-inch wheels that are attached to the frame using an anchoring system. The entire structure can be folded with a single movement and packed in a container that can also be used as a backpack.

Creating water out of thin air—ingenious billboard helps alleviate drinking water shortages

Using the power of technology to help ease water security issues, Peruvian ad agency Mayo DraftFCB and the University of Engineering and Technology in Lima have joined forces to create the first water-generating billboard. Built in Lima, Peru, the innovative structure pulls moisture from the air and condenses it into clean, potable water.

One of the driest places on Earth, Lima receives less than two inches of rainfall per year yet has an atmospheric humidity of around 98 percent - making the city an ideal location for the water-producing billboard. The system collects water from the air, condenses it in a similar manner as an air conditioner and then purifies the water through reverse osmosis. The billboard can generate up to 96 liters of water per day, which is stored in 20-liter tanks and dispensed via a spigot at the bottom of the structure. The billboard has already provided 9,450 liters of clean water in three months of operation.

Xylitol: Uncovering the dark side of this popular sugar substitute

Many of us who have jumped on the lower-carb bandwagon have embraced xylitol as the darling of natural sugar substitutes. And yet, questionable manufacturing processes and the end product can be problematic—that is, a chemically extracted sugar alcohol the body is unable to fully digest which causes an uproar in the digestive tract. To make matters worse, xylitol is frequently made from GMO corn and produced in China. The sugar alcohol is also extremely toxic to dogs and can cause liver failure, as this study found.

Origin and history

Originally developed by French and German chemists in the 1890s, xylitol didn't become well-established on the market until World War II when sugar shortages in countries like Finland forced citizens to seek alternatives. Large scale production of xylitol coincided with the discovery of dental and diabetic advantages in the 1970s. The sweetener is derived from xylan (a polysaccharide), which is present in the plant cell walls of birch and beech trees, rice, oat, wheat and cotton seed hulls, corn cobs and stalks, along with sugar cane bagasse. Due to cost factors, most xylitol today is made from corn, rather than beech or birch. Chemically, all xylitol is the same, although GMOs are often present in non-organic varieties.
