The Hidden World on Our Planet – Life within the oceanic crust

When we go down below the surface of the Earth we go farther and farther away from everything we know and is familiar to us. This makes it hard to imagine how anything could survive there. And yet, microorganisms make this harsh, hostile environment their home. Supported by the circulating seawater and the surrounding rocks these organisms not only survive there but at some places they even thrive.

Infections caused by bacteria can become a serious problem for patients. Antibiotics are often prescribed in such cases. However, a group of small proteins now offers hope in the fight against bacterial infections. These proteins could help address bacterial colonies on implants.

Mathematics as a magical formula – How we explain the world with models

Figure 1 – The Thwaites (Doomsday) Glacier Tongue in West Antarctica. The extent of its area is more than twice the size of Austria, and it is considered an important indicator of the impacts of climate change. For this reason, The Glacier is the focus of numerous studies using mathematical modeling, such as those conducted by the International Thwaites Glacier Collaboration (ITGC).

What do bridges, airplanes, and climate have in common? They can all be described using various mathematical models. But how exactly do these models work, and what role does mathematics play in them? Join us on a short journey through a world full of complex phenomena. Find out here about the role mathematical models play in practice. We’ll show you how they can help us better understand climate change and enable researchers to calculate the impact of gigantic glaciers like Thwaites on global sea levels.

Sugar is not only converted into energy in our body, it also protects us from diseases and infections. This is because nearly all of our cells are coated with a dense sugar glaze. However, if parasites start nibbling on these sugars, it can become dangerous for us.

Imagine being able to enhance your cognitive abilities, boost your physical performance, and even expand your senses—all through implants and prostheses. Sounds like science fiction? In reality, performance-enhancing technologies are already a part of our world. While some celebrate the benefits of these advancements, there are also serious ethical concerns. Will we soon have a society of “superhumans”? What happens to those who cannot afford expensive implants? How will we ensure the safety of these technologies?

Let’s travel back in time again, dig deep into the sediments and see what face Antarctica wants to show us this time! Is it hot and colourful or cool and icy? Or is it both? My “time machine” will bring us back into a climate full of change and mysteries.

“Rainforest in Antarctica” sounds like an April fool? Or like a climate apocalypse scenario for the future? It actually was real. Let’s go deep back in time to the fascinating epoch of the dinosaurs!

Several elements in our climate system are on the edge, e.g. the ice sheet in Greenland… Picture: Pixabay

Global warming should not exceed 1.5°C, according to the Paris Climate Agreement. Fridays for future and other climate activist groups are fighting for this. Why 1.5°C, actually?

Merge or die – The fate of clouds and (covid restricted) cocktail parties

How the fate of simulated rain cells improves understanding of tropical storms. Stay tuned, as we learn about rain tracking algorithms and analyze the merging or decaying of competing clouds. Finally, we will see why cold pools affect cloud clustering similarly, as covid restrictions affect a cocktail party…
