We all know the feeling — some spicy dish attracted our attention, and we dared to try it, only to feel a fire starting in our mouths soon after. Some enjoy this feeling, while others avoid it. Some love the spiciness of red pepper, some prefer hot mustard or raw garlic, and others cannot imagine their plate without horseradish spices and sauces. Whatever it is we’re eating, this taste is the result of our body’s absorption of the spicy chemical weapons that evolution has given plants for protection.
Legend has it that the Aztec emperor Montezuma II would consume dozens of goblets of hot cocoa at celebrations, and the rest of the world loves the delicacy so much that it even celebrates it with international holidays several times a year. Milk, dark, white, liquid… all of it is chocolate in some form or another.
The life of a parasite depends on the well-being and habits of its host. Parasites perform incredible tricks to succeed evolutionarily. For example, they may change the behavior of their hosts or even turn them into zombies. Let’s figure out the who, how, and why behind the most successful parasites in the world.

Unfortunately, Icarus, as keen as he was on flying, violated the latter part of his father’s instruction. Like any legend, this story was a mere allegory until, one day, a daredevil decided to take it literally.

The same ideas often occur to several researchers at the same time. They may also arise in the minds of different species! It’s hard to take something like this at face value, isn’t it? Take a closer look: the world around us is teeming with inventions and mechanisms! They grow under our feet, swim in the water, twitter in the trees. We only need to ﬁgure out how they work, and it can’t be done without a dedicated branch of science — bionics.
This iconic decorative lamp of the 60s is still well-known today. It’s not very functional, but it is hypnotic: the neon-bright “lava” inside grows and shrinks, soars and sinks, mesmerizing us like the flickering hearth that hypnotized our ancestors. Let’s follow the rise and fall of the lava lamp and make our own just from what we can find in the kitchen.
