Let us introduce you today to the best friend of biologists: Caenorhabditis elegans! Why is this terrestrial worm so interesting to researchers?

Pollen is the fertilizing element of plant species, and each species produces grains of different shapes and sizes.

At the South Pole, every year, new layers of snow cover the old ones. The deeper we dig, the further back in time we go.

Colored filaments grow, rise, bud... Strange crossing between the alga, the jellyfish, and the mushroom... Welcome to the fairy world of chemical gardens !

Here, each cell randomly produces a color: red, yellow, cyan or magenta. The researchers have named this technique Brainbow, a contraction of Brain and rainbow. Thanks to this trick, INSERM biologists can more easily follow each neuron in the inextricable web of nerve cells and try to understand the causes of certain brain diseases. …
