One of the most scary creatures of the forest
floor is the centipede. During the night, it
hunts small insects, which are captured and
paralysed by venom, delivered by fang. The
hunting weapon is located right by the
mouth, doubling as the front pair of legs of
the long, segmented body. The toxin from
the fangs is normally not very dangerous
tohumans, but in South America, species
with very painful bites exist.

A cup of ordinary coffee includes 1,000+ different chemicals, the
most prominent of which is caffeine: the most frequently used
psychoactive ingredient in the world thanks to the popular drink.
Caffeine has a beneficial effect on long-term memory
improvement and reduced risk of developing type II diabetes.
Among the other active ingredients are chlorogenic acid, which
functions an antioxidant in the body, and trigonelline: an
alkaloid, which blocks the spread of cancer cells and reduces
blood sugar and cholesterol levels. In the image, you see an
espresso stain. The extreme enlargement reveals how all the
ingredients of coffee are organized in a crystal structure.
