“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.

In one of the last articles we introduced you to the principle of computer tomography. The MAPEX at the University of Bremen X-rays objects, analyses and evaluates the results to gain information about material properties. In this new article, we go on a journey through time. We uncover what was hidden in the past, draw conclusions from the present and evaluate the benefits for the future. The shard shows itself in a new digital guise, which, in addition to new possibilities, also harbours risks.

Long wait for food, shortage of fresh food and water scarcity. These are some of the common problems faced by the displaced people living in refugee camps. Same is the case in relief camps set in places hit by natural calamities like flood, earthquake, drought etc. The previous article was about “Controlled Environment Agriculture”. In this article, you will read about an interesting project called “MEPA” which intends to solve food challenges on earth, especially in refugee camps using CEA technologies.

A scenario shown in the above figure is too challenging to be realised. In future human space exploration missions, our astronauts will face many food challenges when visiting exotic places like the Moon and Mars. Luckily, space engineers and scientists are working on technologies to solve the challenge of growing fresh food in space. In this article you will read about such technologies and understand how farming in space will be really done.
The Science Blog ends the year with an advent calendar full of science! Stay tuned for fun facts, memes and much more.
