No need to stress when the dissertation deadline approaches

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.

When it comes to the giant bacterium Achromatium, everything is everywhere

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.

Deep brain-mediated effects of stress on sleep and immunity

Stress is among the most prevalent causes of insomnia, yet why the brain fails to manage a heathy and proper sleep pattern under stress remains unclear. We clarified a neural circuit located in the deep brain regions implicated in stress-induced insomnia and an extensive suppression of immune function.

Aedes aegypti: Rise of a super-vector

Just as Rome wasn’t built in a day, the mosquito Aedes aegypti did not become the world’s most efficient carrier of human viruses overnight. Our study uncovered the genetic evolution that contributed to turn an African forest-dwelling mosquito into a super-vector.

Finding the novelty in nature

Ecosystems change over time. We devised a way to separate rapid and profound ecological changes from the slow, gradual turnover of species. We used fossil graveyards of microscopic marine plankton that were deposited over millions of years to examine patterns in ’novel communities’ of the past, where they were driven by climate fluctuations and natural disasters rather than human activities.

SARS-CoV-2 induces a sub-optimal immune response that is permissive for viral evolution

The immune system generates antibodies upon infection. However, severe SARS-CoV-2 infection impairs the evolution of antibodies that can bind more tightly to the virus as the immune response progresses. The failure of this evolutionary process in patients generates a suboptimal immune response that might be permissive for the emergence of dangerous variants.
