“Living” Concrete Made From Bacteria

Developed by researchers at the University of Colorado, a new concrete alternative could provide a carbon-free option for buildings in remote places—where lugging traditional concrete ingredients proves difficult. Only two components—photosynthetic bacteria and gelatin—make up this “living” concrete. Due to its photosynthetic nature, it starts off green before drying into a brown hue. Perhaps most impressive of all, the concrete can regenerate: “When half of …

High-Definition Video of the Sun’s Strange Surface

Captured using Hawaii’s Daniel K Inouye Solar Telescope (the world’s largest), this high-definition video of the sun’s surface is the closest observation earthlings have ever seen. Comprised of cell-like eruptions marked by bright centers and darker outlines, this particular swatch of the sun comprises 200 million square kilometers, and each individual “cell” is equal to the size of France. The first of many videos to …

One Dose of Psilocybin May Offer Longterm Relief From Anxiety and Depression
