Researchers at the University of Würzburg have discovered a process that breaks down mRNA molecules in the human body particularly efficiently. This could be useful, for example, in the treatment of cancer.

Circadian clocks control physiological processes and behavior in virtually all living organisms. Now an international research team led by researchers from the University of Würzburg has created a detailed map of the internal clock in the brain of the fruit fly.

Plants adapt their water consumption to environmental conditions by counting and calculating environmental stimuli with their guard cells. Plant researchers from Würzburg report this in ‘Current Biology’.

Pflanzen besitzen zwei getrennte Kalium-Aufnahmesysteme, den Transporter HAK5 und den Kanal AKT1. Je nach Kalium-Konzentration im Boden ist das eine oder das andere System für die Aufnahme von Kalium in die Wurzeln verantwortlich. Das gewährleistet eine konstante Kalium-Versorgung auch bei wechselnder Kalium-Verfügbarkeit.

Plants can extract even the smallest traces of the important nutrient potassium from the soil. A team led by Würzburg biophysicist Rainer Hedrich describes how they achieve this in ‘Nature Communications’.

NEAT1 is genome-protective in human U2OS cells. Accumulation of NEAT1 at DNA double-strand breaks (NGS data, top) and defects in DNA damage signaling in NEAT1-deficient cells (merged confocal imaging data, bottom).

Genome instability can cause numerous diseases. Cells have effective DNA repair mechanisms at their disposal. A research team at the University of Würzburg has now gained new insights into the DNA damage response.

The current cover photo of “Aging Cell” - here is an excerpt - refers to the Würzburg study.

Numerous studies have shown that the older the father, the higher the risk of disease for the offspring. Human geneticists at the University of Würzburg have now taken a closer look at the processes responsible for this.

 The common carder bee (Bombus pascuorum) feeding on the large-flowered hemp-nettle (Galeopsis speciosa) in the Austrian Alps. If it gets too hot, the insects can hardly detect the scents of the flowers.

It's not just us humans who suffer from heatwaves. Researchers at the University of Würzburg discovered that hot temperatures rob bumblebees of their sense of smell – and makes them struggle when searching for food.
