New Bike Tires That Will Never Get Flat

A flat tire is a thing that can ruin even the best bike trip. However, riders can forget dragging around their patch kits and pumps, because Nexo created an airless tire to ensure they keep pedaling.
Flat-free tires aren’t new, however they weren’t widely used because of poor stiffness and shock absorption, compared to the conventional ones. But this Utah-based company claims to have found a solution to these problems. The tires are made from polymeter blends that are said to offer not only a perfect balance of cushion and resilience, but durability as well. The product comes in two different shapes – tires to be mounted on existing wheels with a lifespan of up to 3,100 miles, and others, which replace the entire wheel set and last for up to 5,000 miles.
If that’s not enough, Nexo made their products from a single material, which makes recyclability really easy. Considering that 10,000,000 tons of bike tires and tubes are discarded every year, that’s certainly a step in the right direction.

How Sand Looks Magnified Up To 300 Times


Comparing something to a grain of sand is usually supposed to mean that it’s small or insignificant, but Dr. Gary Greenberg’s microscopic photography aims to turn this stereotype on its head. His photographs of miniscule grains of sands magnified up to 300 times reveal that each grain of sand can be beautiful and unique.


Greenberg’s story is a fascinating one. First of all, he invented the high-definition 3D microscopes that he takes his pictures on, resulting in 18 U.S. patents under his name. He was a photographer and filmmaker until age 33, when he moved from LA to London and earned a Ph. D. in biomedical research. This seems to have given him a unique appreciation for biological and scientific curiosities and for the optical technologies he would need to document them.


Sand composition can vary drastically depending on where it’s located. The coastal sands in Hawaii, where Dr. Greenberg is located, are very likely the subjects of his amazing micro-photography. The sand in his images is full of remnants from various tropical sea organisms large and small. The sand on other coasts, depending on the temperature, surf conditions and marine environment, may include a totally different set of rocks, minerals and organic matter.
