STEB: Advanced

You are competing in this category if you have already participated in STEB during the previous school year.

Apart from that, if you are in the last year of high school, but enter STEB for the first time, you may also compete in this category. 

Series 1: Genetics and Nature Conservation

Did you know that mass extinctions have occurred at least five times on Earth? Most of the species living at that time became extinct due to geological, climatic or other factors.

But in the first of this year's series, we'll look at the present, where the rate of species extinction is hundreds to thousands of times higher than the average rate of extinction over millions of years of life on Earth. Scientists warn that we are currently in the midst of the sixth mass extinction, and one of the Earth's species - ours - is causing it.

Deadline for this series is midnight, November the 6th 2022.

Series 2: Genetically modified organisms

Have you ever seen a "GMO free" sign in the supermarket? What does it mean? Why are genetically modified organisms (GMOs) a cause for concern in society and why is their use strictly regulated in many countries? In this article we will take a closer look at the issue of GMOs and try to answer these and other questions about them. 

Deadline for this series is midnight, December the 30th 2022.

Series 3: Origin of Eukaryotes

The emergence of the eukaryotic cell is considered one of the most fundamental events in the history of life on Earth. It enabled the evolution of organisms made up of cells that differed significantly from those previously found and ultimately led to the evolution of sexual reproduction, multicellularity, specialised cells and complex organisms such as mammals. But how did these complex cells evolve?

Series 4: The ongoing battle between prokaryotes and viruses

Prokaryotes are unicellular organisms living in almost every known environment. They live in seawater, in soils, in your body, in volcanic pools, in black smokers, and even in the Earth's crust. Prokaryotes are extremely important: the world as we know it would not exist without them. 

However, they are under constant attack by viruses - phages. Let's look at their defense mechanism and investigate how they are able to survive in this never-ending battle. 


Series 5: The early hominins

All humans currently living on the planet Earth are members of the species Homo sapiens. We are the most numerous and widespread species of mammals inhabiting the Earth.

How did we come to be so widespread, numerous and successful? Where do we come from?
