Pollution levels in the Indian capital this month have rivalled 1952 London, when smog killed around 4,000 people, pollution experts say. 

A new field of science is being developed by Lancaster researchers who are discovering the underlying mechanisms of interaction behind everything from the human body to climate change.

Un equipo de científicos de la Universidad Nacional de Singapur (NUS) ha desarrollado un dispositivo prototipo que imita la fotosíntesis natural para producir gas etileno utilizando solo luz solar, agua y dióxido de carbono. El nuevo método, que produce etileno a temperatura y presión ambiente utilizando sustancias químicas benignas, podría ampliarse para proporcionar una alternativa más sostenible y ecológica al método actual de producción de etileno.

Without countermeasures, climate change will negatively impact animals in pig and poultry production. Beside the health and wellbeing of the animals, heat stress also affects performance and, as a result, profitability. As the animals are predominantly kept in confined livestock buildings equipped with mechanical ventilation systems, researchers at Vetmeduni Vienna examined the inlet air temperature of several air cooling systems. The best solution, they found, is the use of the earth for heat storage via an earth-air heat exchanger (EAHE). An EAHE cools in the summer, and warms up the inlet air during wintertime.

A team of scientists from the National University of Singapore (NUS) has developed a prototype device that mimics natural photosynthesis to produce ethylene gas using only sunlight, water and carbon dioxide. The novel method, which produces ethylene at room temperature and pressure using benign chemicals, could be scaled up to provide a more eco-friendly and sustainable alternative to the current method of ethylene production.
