✯ Nerve cells and glial cells, coloured scanning electron micrograph (SEM). The nerve cells have small cell bodies (pink) and fine extensions called axons and dendrites (mauve). The glial cells have large cell bodies (brown) with thicker extensions (mauve). Neurons are responsible for passing information around the central nervous system (CNS) and from the CNS to the rest of the body. Glial cells are nervous system cells that provide the neurons with structural support and protection.✯

"Tardigrades are microscopic animals that live in moss and the muddy sand on beaches. They can survive high temperatures, freezing, and crushing pressures by drying themselves up into a little hard ball, called a tun. Stick a tun in water and [...] it will rehydrate and regenerate back into a tardigrade. [...] It may well be the most adorable genome on Earth."
