Our Living World - Cells to Bats to Humans
Zoonoses in the Night
Since the COVID19 pandemic, more people have become aware that bats are recognized as the original hosts of some novel emerging infectious viral diseases, harming their reputation, and threatening their conservation.
It is not surprising that bats are original hosts of some novel viruses. A novel virus is likely to come from an animal anyway, and the number of viruses in bats is just proportional to the number of bat species around. Novel infectious viral diseases arise as an effect of how humans interact with animals and their habitats. To provide guidance in making the right choices regarding our interactions with bats, it makes sense to know the variation of viruses that occur. Therefore, we investigated virus diversity of bats, and the type of contacts existing between humans and bats in the Netherlands.

Does Size Matter?
On average, men are taller than women and weigh more, and the dimensions of their hearts and blood vessels are also slightly bigger. When men or women require surgery on their heart, the criteria for undergoing surgery are however the same for men and women. Is this OK?
Let’s take the example of patients whose main artery emerging from the heart (aorta) is abnormally large (thoracic aorta aneurysm).During this talk we will explore male-female differences in thoracic aortic aneurysm: are their differences between men and women in disease diagnosis, progression, and outcome? Do they get the same surgical treatment? And how do they cope with this horrible disease?

How Life Works
All life is made of cells, which are the smallest units of life that are themselves alive. Cells in turn are made of a complex mixture of molecules that are themselves lifeless. How do lifeless molecules interact to form a living cell that sustains itself, grows and replicates? In the large nation-wide BaSyC program, we aim to build a synthetic cell from the bottom up in order to understand ‘how life works’. In this talk I will explain how we build synthetic cells in the cell and what we have learned so far about the inner workings of the cell.
