Foraminifera (Latin for “hole bearers”, informally called “forams”) are single-celled organisms that usually have a multi-chambered shell, which can be built in various ways depending on the species. They are the stars of the FORAREX (FORAminifera Rocket EXperiment) project, in which we investigate their behaviour and shell growth under microgravitational conditions.

Surely, everyone has wondered how 99 Festivalbesucherinnen (female festival visitors) become 100 Festivalbesucher (male festival visitors) as soon as one man stumbles into the dancing and partying mob. Poof, all the confidently partying women are just gone.

Fungi: Here, There and Everywhere

by Vivienne Vent

Eatable, inedible, deadly. Tiny and of enormous size. Hardly any life form is as diverse as that of the fungi. Neither they can be called animals nor plants, they form their own taxon amongst the living organisms. Even though, they are a big part of our nutrition, we barely know how complex these organisms actually are. For example, did you know that the planets biggest living organism is in fact a fungus? Or did you know that fungi made the evolution of many life forms on earth possible by establishing complex interactions aka symbioses? Find out more about these fascinating organisms!

The IPCC (The Intergovernmental Panel on Climate Change) published its sixth report about the latest findings about climate change and the news are full of it. Again, fundamental questions about our modern lifestyle arise, which strongly influences our environment. The IPCC-report contains most important information, but not everyone finds time to completely read through the report. In the present article we provide the most important statements of the report.

How we can become spiderman

by Manuel Vollbrecht

Figure 1: Running up walls and jumping over roofs like Spiderman for once…. ¹

Every single person has probably imagined once what life as a superhero with special skills would be like. Of course, we all know that most of the skills that actually define superheroes are supernatural and (unfortunately) come entirely from the imaginations of the authors and filmmakers.

Steps Back into the Past of the Ice Cores and the Planet

About Ice Cores Part III

by Hanna Sophie Knahl

Ice cores preserve stories of the past. Now we want to compare these stories  with other history books. Illustration: Hanna Knahl

We have now already learned a lot about ice cores. We know where to find them, how to drill them and how to extract information about the past climate from them. BUT there is still one important piece of information missing. The time stamp. How do we determine how far back in time the ice we hold with our gloved hands comes from? We will see, the ice also uses special languages to encode this secret.

The Studies of the Historical Books Made of Ice

About Ice Cores Part II

by Hanna Sophie Knahl

In the first article about ice cores, we learned why ancient stories lie dormant in the ice. We got to the icy library and looked at how the stories can be recovered in the form of ice cores. This article will deal with the question how we can reveal the stories of the ice cores. To do this, we need to understand the different languages of the ice.

The Story of Giant Libraries Made of Ice

On earth there is a lot of ice and snow and not only in winter – at least at the moment. At the poles there are huge sheets of ice and in between exist many smaller and larger glaciers on high mountains. Stories are preserved in the ice. Stories from long ago. How this happened and how these stories can be brought to the surface, we will learn in this article.
