Bioinspiration, also known as biomimicry, is the practice of drawing ideas from nature’s designs to create innovative technologies. Over millions of years, nature has been vital in solving many challenges through evolution and scientists often studied these solutions to develop more effective, innovative, sustainable and efficient human-made products, which help the survival of humanity and other species. One of the most remarkable examples is shark skin, a solution which has inspired many...

Glue, or adhesives, appears to be pretty mundane material—just apply it and stick things together. But what's really interesting is that there's some pretty cool chemistry going on at the molecular level when you apply glue. Adhesives are materials that stick two surfaces together using a combination of physical and chemical forces. The trick is finding a balance between adhesion (how well the glue sticks to the surfaces) and cohesion (how well the glue sticks to itself). How does glue work?...
