Scientific applications often require an exact reconstruction of object positions and distances from digital images. Therefore, the images need to be corrected for perspective distortions. We present CameraTransform, a python package that performs a perspective image correction whereby the height, t... 

Emperor penguins (Aptenodytes forsteri) breed during the harsh Antarctic winter. During mating and breeding period (in total up to four months), the males must fast, while also incubating the egg during the latter. To survive and breed successfully, they must conserve their energy. Through evolution... 

In-vitro engineered cardiac tissue grafts are of growing interest for different applications such as substituting scarred myocardial tissue after infarction or chronic cardiomyopathies, or as a drug testing platform. Several studies have recently reported successful fabrication of microtissues from s... 

Automated image based tracking is widely used to investigate collective interactions in a variety of biological systems. Applied to diverse environments, ranging from cell to animal colonies, it provides insight into biological processes like cancer metastasis, immunological response, and social str... 

Cell migration through a three-dimensional (3-D) matrix depends strongly on the ability of cells to generate traction forces. To overcome the steric hindrance of the matrix, cells need to generate sufficiently high traction forces but also need to distribute these forces spatially in a migration-pro... 

Many cell types in our body, such as fibroblasts, immune cells but also cancer cells, are able to actively migrate and squeeze through the tiny pores and cell layers in our tissue. Similarly, blood cells are passively pushed and squeezed through narrow capillaries. In both cases, the deformability o...
