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!

Climate Special – Theory

by Hanna Knahl

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…

Clouds can party hard!

Clouds like to cuddle and cluster. Cloud clustering is crucial to understanding the formation of tropical storms. This article will brush up your basics on convection, introduce you to fascinating atmospheric phenomena and reveal, how the clustering of clouds can be compared to a cocktail party…

Pastry chefs use a very similar method to 3D printers – they make their cakes in layers. In doing so, they encounter problems that also arise in metal 3D printing – the layers must be uniform to produce a beautifully shaped cake or a dimensionally accurate component. There are new findings from the science confectionery about how to achieve the uniformity of the layers in metal 3D printing.

Space rockets are rigid giants that overcome the Earth’s gravity with unimaginable force and reach outer space. But are they really as rigid as they look from afar? You have probably never sat IN a rocket to be able to judge that from close up. This article takes you to the inside of a rocket and what goes on there.
