Immune cells can move within our body, even between firmly attached cells. How do they overcome these impediments? Studying fruit fly embryos, we have discovered that immune cells take advantage of dividing cells. Because intercellular attachments disassemble during division, it creates a weak spot in the dense tissue, through which immune cells can migrate.

Recently, we developed a new way to identify SARS-CoV-2 antibodies without blood samples and needles. The assay detects these specific antibodies using urine instead of blood samples. Thus, people unable to perform blood puncture will be able to benefit from the possibility of checking for the presence of anti-SARS-CoV-2 antibody produced after a recent infection without any need for a needle.

Quick breakage of lizard tails to escape predation has remained a mystery for centuries. Our study explains the balance between firm attachment and the quick release of the tail and highlights the lizard's way of achieving the “just right” connection for its best chance of survival.

Volcanic hotspots like Hawaii are usually thought to be fed by hot blobs inside the Earth. A new class of cold hotspots is identified by inferring the temperature from Earth’s CT-scan. Scientists need to figure out a new theory to explain its mysterious origin.

We find that students are not more stressed or handle their stress differently at different points during the dissertation year. However, stress and coping are connected to tasks and challenges at hand. Additionally, students change their thinking about the dissertation over time. First, the dissertation is new and negatively perceived, then as a challenge and in the end negatively again.

Unlike typical bacteria, the giant Achromatium contains hundreds of unidentical chromosomes. Achromatium is present globally in different environments. This typically leads to speciation. Nevertheless, Achromatium shows minimal environment-specific phylogenetic differentiation. Instead, it harbors a globally identical functional inventory for which uses genes it needs for the specific habitat.
