How chemists are building molecular assembly lines

Four huge robot arms surround the gleaming metal shell of what will soon be a top-of-the-range automobile. They jerk into life, attaching the bonnet, the wing mirrors, and other panels. It’s the kind of precision operation you can find at car factories around the world these days. But here’s a question worth considering: could we pull off a feat like this only about a billion times smaller?

Plant-based, probiotics and vitamins: what new diets mean for farmed fish health

Farmed fish are increasingly becoming vegetarian, with plant-based feed now widely used in Europe. Researchers now want to optimise feed to promote fish growth and nutrition. To do this, they are studying fish gut bacteria and the impact of probiotic additives as well as testing nutrient supplements.

Q&A: Why unconventional resources are key to expanding geothermal energy use

The smouldering heat generated during the formation of our planet and the continuous decay of radioactive material lies trapped within the Earth’s crust, just waiting to be tapped to satisfy humanity’s insatiable demand for heat and electricity.
