The secret of the roseCryptomeria japonica pollen

Petals of roses seem to be smooth. But at magnification of 149-times, a thick fur appears. The individual hairs are up to half a millimetre long. They only grow on the outer side of the petals. What they are for, remains a mystery. Probably, they serve as protection against rain, insects, or the touch of neighbouring roses.

Airborne Chemical CocktailCryptomeria japonica pollen

Pollen grains contain the promise of new life. But on the way to the female flower many things can go wrong. For instance, the grains could end up as a meal for fungi. The Japanese cedar solved this problem by impregnating the pollen wall with defence chemicals. They fend off fungi but they also cause severe allergic reactions with 10 percent of Japan’s society.

Varroa Mite

The destroyer

It has stronger arms than a sumo wrestler, a better nose than a dog, and its bite is more deadly than that of a cobra.
Its victims: millions of bee colonies worldwide.

Belly Button MicrobesThe Navel of the Bacterial World

The belly button is a forgotten part of the human body. Scientists ventured into it in the search for life and found it thousandfold.

Mosquito egg surface

The More Harmless Mosquito

Mosquitoes are despised as transmitters of diseases. But they also have a peaceful side. As larvae, they sweep the surface of ponds and lakes with their mouth brushes.

Drosophila Eye Development

Blind Flight of the Genes

The genome is one of the most powerful entities in the body of living organisms. If some parts of it are broken, things can go wrong. No other creature shows this better than the fruit fly.

Intestinal Bacteria

Feeding Frenzy in the Gut

Bacteria are the heroes of our digestion. They split carbohydrates for us, supply us with essential vitamins and protect us from intestinal diseases.

Micronaut-Fine-Art-Euglena_archivCyclops in a Kilt

It is a bacterium, a plant and an animal at the same time and almost as old as life itself. Euglena is so ingeniously built that researchers stilldo not fully understand how it works.

Mosquito egg surfaceFrom Mouth to Mouth

This section analyzes and explores invisibly small structures, and explains the scientifically relevant facts behind Micronaut’s artistic works! The current topic presents you with the moth powerful snout of the world – the mouth of the Springtail (Collembola sp.). Springtails are found in leaf litter and soil. With estimates of 100’000 per cubic metre of topsoil, they are essentially everywhere on Earth.

Mammalian Adipose Tissue - Fat CellsFat Buddies

Fat cells are considered a nuisance because they give us bellies and flapping upper arms.
But without fat our species would have gone extinct long ago.

Calcitic Microlens Plate

Skeleton Eyes

Brittle stars look almost the same as sea stars, but they are only as big as an outstretched human hand. Their evolutionary history goes back 500 million years into the past, which means they belong to the dinosaurs of the seas. Since then, they have changed little. Their current design is almost the same as during primeval times, but in one of the species researchers have discovered a piece of high technology: the brittle star species Ophiocoma wendtii has the ability to detect light and shade… !

Stealth Eyes

Moths have an ambivalent relationship to light: during the night they love it, because it helps them to navigate, but at daytime they must avoid it under any circumstances, because it would instantly betray them to an army of hugry predators… !

Streptococcus bacteria


The picture shows one of the biggest killers of humanity: the pneumococci (Streptococcus pneumoniae). These bacteria possess a kind of armour made of long sugar molecules that make them inaccessible. Moreover, this armour has a negative charge, which prevents them from adhering to surfaces. Like rubber balls the bacteria bounce off and work their way through the airways deeper into the body until they end up in the middle ear or in the lungs. There they strike… !

Fungi fruit bodies

The Fungal Plague

With the summer storm comes death. The freshening wind has blown a single spore of a rust fungus on a plant leaf. There it takes a rest and waits for the rain. When the humidity finally reaches 100 percent, it germinates and begins its deadly work… !

Surface of a Grass leaf

Blades of Steel

Grass is the staple food for many organisms ranging from mammals, insects, and even fungi. That does not mean that grass makes an especially good fodder. Quite the contrary is the case. It does everything possible to spoil the appetite of the herbivores… !

Micro Robots

Army of Micro-Robots

What appears to be lined up lollipops, are in fact micro-robots. They are only half a millimetre in diameter. At the moment they are still fixed with two short arms on a silicon plate. But as soon as the laser cuts them off, they are ready for their first mission… !

Pine Pollen

The pollen grains of most conifers possess two inflatable bags. They look like little parachutes and for a long time researchers have thought that they represent some kind of flying aid… !

Fibrin Network of the Blood

Contact Adhesive in the Blood

The human body is basically a fluid-filled cavity. Thus its greatest enemies are sharp objects and knives. If they bore into the fine network of blood vessels under the skin, we literally run out. But not for long. Just ten seconds after an injury, an automatic process starts that seals the hole within a few minutes. We all know it as ‘blood clotting’… !

Snowdrop pollen

Sperm in Concrete

Nothing is more important for flowering plants than their sperm. They are the carriers of the genetic makeup and its protection is essential in the struggle for life. In order to guard their sperm, the plants pack them into tiny containers, which are generally known as ‘pollen’… !

Mammalian sceletal muscle


The Mechanical Muscle

My grandfather was a mechanical engineer. He could spend hours poring over a technical problem. At some point he sat down at his drawing board and drew the solution with a sharp pencil and a ruler. However, his favourite problem he had never solved: How do you build a muscle… ?

Fly proboscis


The Ruminant Fly

You are looking at a fly’s tongue. The wave-like structures in the upper half are part of a pad that resembles the floor brush of a vacuum cleaner. The lower part of the image displays the beginning of the ‘hose’. So we take the perspective of a food particle that is about to be sucked in… !

Helicobacter pylori infection


David versus Goliath

Gastric cancer is one of the most common and often fatal cancers: Every third cancer death is due to gastric carcinoma. The main risk factor for the development of gastric cancer is chronic infection with an (almost) invisibly small pathogen – the stomach bacterium Helicobacter pylori…. !

Mammalian sceletal muscle fibres


Understanding Muscular Disease

Congenital muscular dystrophies are severe diseases of the skeletal muscle, often characterized by heterogeneous genetic origin and early onset. Mutation of the gene encoding laminin-alpha-2, which plays a major role in the organization and function of the muscle basement membrane, leads to severe form of muscular dystrophy and patients often have trouble with the breathing and cannot stand or walk…

Mosquito egg surface

Superhydrophobic Surfaces

Water repellent surfaces are under thorough study and various examples can be found throughout the plant and animal kingdom. Particularily the characteristics of waxy surfaces are well known. By preventing water from touching the whole surface, elastic hair-like structures are responsible for the famous self-cleaning properties of Lotus leafs (Nelumbo nucifera)… !
