In aerobic life forms, reactive oxygen species (ROS) are produced by the partial reduction of oxygen during energy-generating metabolic processes. In plants, ROS production increases during periods of both abiotic and biotic stress, severely overloading the antioxidant systems. Hydrogen peroxide (H2O2) plays a central role in cellular redox homeostasis and signaling by oxidising crucial cysteines to sulfenic acid, which is considered a biologically relevant post-translational modification (PTM).

- In two experiments, researchers studied how people maintain preferred distances from drones compared to human interactions, focusing on factors like drone height and approach angle.
- The first experiment showed that people prefer to stay farther away from drones, especially when the drone is hovering at a higher altitude.
- The second experiment explored various drone designs and found that adding human-like features led to even greater preferred distances, highlighting the importance of social perception and perceived danger in designing effective human-drone interactions.
In the diatom , iron limitation promotes a decrease in the content of photosystem II, as determined by measurements of oxygen-evolving activity, thermoluminescence, chlorophyll fluorescence analyses and protein quantification methods. Thermoluminescence experiments also indicate that iron limitation induces subtle changes in the energetics of the recombination reaction between reduced Q and the S/S states of the water-splitting machinery. However, electron transfer from Q to Q, involving non-heme iron, seems not to be significantly inhibited.

We aimed to study type 1 diabetes incidence in European childhood populations to assess whether an increase could be attributed to either period or cohort effects.
Methods: Nineteen EURODIAB centres provided single year incidence data for ages 0-14 in the 25-year period 1989-2013.
