A giant mural in Warsaw that absorbs pollution like 780 trees

A giant mural located in Warsaw (Poland), next to the Politechnika metro station, has been painted by local artists Dawid Ryski and Maciek Polak using special pigment. Such pigment has been created as part of the Converse City Forests project that, through murals, aims to cleanse pollution from the environment as if they were real trees. The pigment uses light energy to break down harmful pollutants in the air and turn them into harmless substances like nitrates…

Producing electricity using the shadows

Solar panels have a main problem, they cannot always be used. They have to be outdoors and it has to be sunny. A new device, developed by a team at the National University of Singapore, takes advantage of the difference between shadows and light to generate energy from darkness, so it is much more effective than solar panels. Its generates energy when part of its solar cells are not receiving direct sunlight…

3D printed houses in just 48 hours

The construction of 3D printed houses has been trying to take off for several years, but is still in an initial stage. However, a company in the Czech Republic, Prvok od Burinky, has presented an ecological, solid and stylish house that can be built in up to 48 hours, around seven times faster and costing half as much as a brick house. With three rooms and a living area of 43 square meters, the house will be built layer by layer using a reused robot arm from the automotive industry…

A Norwegian village with sunlight thanks to three huge mirrors

Did you know that vitamin D keeps depression away and regulate circadian sleep cycles? The biggest natural resource of such vitamin is natural lighting. However, there are places on our planet where people receive very few hours of sunlight, especially in certain seasons. In a remote Norwegian town called Rjukan, people live without light for six months a year! The reason, the shadow of the mountains surrounding their deep valley do not let the sun light the streets…

A new high-resolution robotic eye wired to the optic nerve

A group of researchers from the University of Hong Kong (China) have managed to create the most accurate artificial replica that exists of a human eye. The prosthesis is completely autonomous, works with solar energy and replicates the retina of the human eye with a viewing angle of 100º (only 30º less than a real human eye)…

Achieved partial recovery of vision in blind mice

A study, published in the journal Nature, shows the partial restoration of vision in blind mice using a method that chemically generates new photoreceptors, the cells responsible for converting light into nerve impulses that the brain transforms into images. Experts hope to move therapy to humans in 2-3 years. The method consists of chemically reprogramming dermal fibroblasts (a type of cell that serves to maintain the structure between tissues and heal wounds) to photoreceptor cells similar t…
