People in cities hold the key to ensuring a sustainable future

Cities have a critical role to play in fighting climate change but hard conversations lie ahead about the best way to achieve the transition to sustainability, according to Harriet Bulkeley, professor of geography at Durham University, UK.

Green fertiliser made from cow dung and chicken feathers could transform big agriculture

A raft of strategies is being trialled in Europe to turn nutrient-rich farm waste such as chicken feathers, cow dung and plant stalks into green fertiliser. Full of phosphorus and nitrogen, recycled products could help reduce intensive agriculture’s emissions and reliance on fertiliser imports.

Why meerkats and mongooses have a cooperative approach to raising their pups

Raising children can be a tough job, especially when doing it alone, but some animals like meerkats and mongooses work together to raise their young. Studies of these cooperative creatures are revealing how this highly social behaviour evolved and is shedding light on the roots of our own species’ collaborative abilities.

Which climate innovations will really limit global warming?

From a chemical-free spray that turns sand into lush green land, to a caterer who serves planet-friendly dishes, and from technology that makes stronger concrete with less cement, to insect farms that produce fish food and fertilisers, there is no shortage of ideas to reduce emissions. But which ones work best?

Jellyfish researchers want you to start thinking about these creatures for your next meal

A few summers ago, Stefano Piraino was walking along the rocky shoreline on a small island off the coast of Sicily when he spotted a washed up jellyfish. Naturally, he tore a piece off and popped it into his mouth.

Aeroplanes could cut emissions by flying on waste cooking oil fuel

Blending biofuels and kerosene to create greener jet fuel has shown promising results in test flights, but more work needs to be done to ensure biofuels burn cleanly and can be produced in a large-scale, low-cost way, says Dr Chong Cheng Tung, associate professor at the China-UK Low Carbon College of Shanghai Jiao Tong University in China.

Small farms produce more food than statistics show

Small farms sometimes get overlooked as a feasible solution for feeding a growing population, but researchers say they should be given greater support, with some producing more food than official statistics report.

‘Young scientists share protesters’ sense of urgency on climate’

Young scientists have the ambition, disruptive thinking and sense of urgency to drive clean energy forward at the radical pace that is needed, says Luciana Miu, a PhD student in chemical engineering who is focusing on energy efficiency at Imperial College London, UK.

Rare crops crucial to protect Europe’s food supply, boost health

Rye bread or porridge oats may not be everyone’s first choice of breakfast, but scientists say Europeans need to broaden their taste in cereals both to boost their own health and to protect the future of Europe’s farming.

Chemical mixtures pose ‘underestimated’ risk to human health say scientists

Each of us harbours hundreds of man-made chemicals inside our bodies because we are exposed to them in our daily lives. While individual chemicals may not be of immediate concern to public health, scientists now worry that certain mixtures of them may pose previously underestimated risks to health.
