Mechanisms and consequences of horizontal gene transfer in cell wall-deficient cells of Kitasatospora viridifaciens
The bacterial cell wall is a nearly universal structure that offers protection and gives the cell its shape. However, environmental stressors, such as cell wall-targeting antibiotics and hyperosmotic conditions, can induce bacteria to shift to a wall-deficient state. It is unknown whether the lack of…

The electrochemical reduction of dioxygen and hydrogen peroxide by molecular copper catalysts
The electrochemical oxygen reduction reaction (ORR) is an essential half-reaction for the utilization of hydrogen as a sustainable fuel, via the conversion of hydrogen to electrons and protons facilitated by the ORR. In the most common fuel cells, the ORR is requires high loadings of non-abundant platinum…

Discovery and exploitation of the transcriptional regulatory system of pectinases in Aspergillus niger
Pectin is a plant cell wall polysaccharide made of mainly D-galacturonic acid (GA) subunits. The potency of the filamentous fungus Aspergillus niger to naturally secrete high amounts of pectinases to degrade pectin has been utilized for the industrial production of pectinases.

Conspiracy thinking and social media use are associated with ability to detect deepfakes
Deepfakes zijn video’s die gemanipuleerd zijn om twee personen te verwisselen. Ze kunnen moeilijk te onderscheiden zijn van de originele video’s. In onze studie laten we zien dat mensen die meer complotdenken en mensen die meer gebruikmaken van social media beter zijn in het herkennen van deepfakes.
