The global climate is in an imbalance. Potential "tipping elements " include the Greenland ice sheet, coral reefs, and the Amazon rainforest. Together they form a network that can collapse if just one individual component tips. Researchers from Bonn University Hospital (UKB) and the University of Bonn have now shed light on seemingly sudden and rare, often irreversible changes within a system, such as those that can be observed in the climate, the economy, social networks or even the human brain. They took a closer look at extreme events such as epileptic seizures. Their aim was to better understand the mechanisms underlying such changes in order to ultimately make predictions. The results of their work have now been published in the journal "Physical Review Research".

Concerns over health and freshness are keeping many shoppers from embracing frozen foods, a new study suggests - despite their potential to reduce food waste, cut carbon footprints, and offer affordable nutrition.

The research, published in the British Food Journal, explores why consumer resistance to frozen food remains stubbornly high, even as global demand for sustainable and convenient food options grows. The study found that anxieties around nutritional quality and freshness fuel health concerns, which in turn drive resistance to buying frozen products.
