Spider silk is mainly composed of particular proteins called fibroins. These proteins form molecular chains that combine very strong regions with more elastic regions. This...
Butterflies have a highly developed vision capable of detecting colors that we, humans, cannot always perceive well. They see particularly well in the ultraviolet spectrum, a range...
Plastics are polymers, large chains of molecules that are very chemically stable, which means they last a long time. Especially since most of them, like...
Refraction is when light changes direction when passing from one transparent medium to another, such as from air to water. This bending occurs because the...
Frog rains are generally caused by intense weather phenomena such as waterspouts or tornadoes. When these violent whirlwinds pass over bodies of water or marshy...
Halley's comet orbits the Sun in a highly elongated elliptical path, somewhat like a stretched rugby ball. At its closest point to the Sun, the...
Olive oil is rich in monounsaturated fatty acids (mainly oleic acid), with few polyunsaturated fatty acids. In comparison, sunflower oil mainly contains polyunsaturated fatty acids...
When liquid water cools down, its molecules gradually lose their thermal agitation (basically, they slow down their movement). Around 0 °C, the temperature drops enough...
Bleach is a solution based on sodium hypochlorite (NaClO). The main thing you'll find in it is this hypochlorite, usually mixed with water and a...
When you immerse an object in a liquid, it experiences an upward force called buoyancy. Essentially, this means that a submerged object appears lighter because...
