The inside of story of a pioneering programme to convert nitrogen into microalgae that can generate sustainable animal feed.

Months not eating or moving don’t result in muscle wasting and loss of function for animals that hibernate. New research found gut microbes help their hosts hold onto and use nitrogen to build proteins.

If we want to reduce carbon emissions and preserve planetary ecosystems, we need to protect our soils.

Legumes have a superpower: they can convert nitrogen in the air into a form plants can use to grow.

A lack of policy has allowed industrial chicken farms to multiply in certain parts of the UK – with a lack of consideration of the environmental and social impacts.

Scientists need to know how much we can rely on the land to offset our emissions.
