Do walking and cycling make people healthier, or are healthier people more inclined to travel actively? And how does the coronavirus affect our travel behaviour? These are the kinds of questions that scientist Maarten Kroesen is investigating. In his view, situations are often not as simple as they might seem at first glance. He is nevertheless convinced of one thing: we should be walking and cycling more.

Copper is important for many processes in our body. Among other things, it supports the production of red blood cells, metabolism, and the formation of connective tissue and bones. Copper is also known to play a role in diseases such as cancer, diabetes and Alzheimer's disease. Unfortunately, we do not yet know exactly what that role entails. Researchers from Delft University of Technology and the Polish Academy of Sciences have now discovered a new piece of the puzzle. In order to be able to do its work, copper binds to different types of proteins in the cell. And although the complexes that are formed in this process are not harmful in themselves, temporary 'intermediate forms' appear to arise during the binding, which can lead to damage to the cell. The results of the research have been published in Angewandte Chemie.

The Social Distancing Dashboard creates city maps that show on a street and neighbourhood level if social distance rules can be respected when moving in public space.

For patients hospitalised with COVID-19, the battle is not just a physical fight against the virus, it’s a psychological struggle against isolation. Witnessing the impact of isolation on coronavirus patients, the Renier de Graaf Hospital in Delft reached out to scientists at Delft University of Technology to ask for help in developing an easy-to-use and secure communications platform.

Dutch people believe that any relaxation of measures to control the coronavirus should be limited, in order to prevent the healthcare system becoming overstretched. They also think that the measures should not be allowed to sow division: there is no support for lifting restrictions for specific groups.

In a very short period of time, students involved in OperationAIR have successfully developed an emergency ventilator for coronavirus patients. Following the necessary test procedures, the design of the AIRone – including all related documentation – has now been released online so that other countries and initiatives can also benefit from it.

The researchers of Project Inspiration have made all of the designs for their mechanical ventilator available worldwide. In this way, the team hope to reduce the shortage of ventilators in the Netherlands and abroad. In addition, a test model has been prepared, and it will soon be sent to Guatemala.

TU Delft researchers will be asking people in the Netherlands on how they would prefer coronavirus measures to be relaxed. From 29 April, anyone will be able to make their preferences known at www.tudelft.nl/covidexit.

Scientific research into the world-famous painting by Johannes Vermeer, known as the 'Girl with a Pearl Earring', has yielded new insights. TU Delft researchers played an important role in making discoveries about the brushwork, the use of pigments and how Vermeer built up his painting with various layers of paint.
