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.
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?
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.
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 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 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.
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.
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.
An estimated 5.25 trillion particles of plastic float in Earth’s oceans, threatening not only the health of marine ecosystems and animals, but that of humans in the water we drink and the food we eat. However, research into the extent of the dangers posed by microplastics is still just in its infancy.
Little is known about deep ocean environments. But scientists focussing on the depths of the North Atlantic are now learning more about their ecosystems - including the role of vast sea sponge grounds – and how to safeguard them against the effects of climate change and industry.
Removing immune-stimulating sugars should also help people with red meat allergies.
Newly domesticated horses may have increased the spread of disease.
