Root architecture discoveries could help breed drought-resistant crops

A freesia's root architecture helps the plant store food to survive seasonal weather conditions.

We should breed new varieties of crops based on their root architecture rather than just focusing on the top half of the plant, according to scientists looking at how to cultivate plants that use water more efficiently and better withstand drought conditions. Yellow, parched fields were a common sight in Europe this summer. The severe … Read more

Climate actions that lift people out of poverty are often most cost-effective

Limiting global warming to 1.5°C would save hundreds of millions of vulnerable people from being exposed to the extremes of a 2°C world.

The most cost-effective climate change actions are also those that could help us achieve sustainable development goals (SDGs) such as ending poverty and hunger, according to Dr Keywan Riahi, director of the energy program of the International Institute Applied Systems Analysis (IIASA) in Austria, who says the first step should be to cut our energy … Read more

Studies linking green space to lower suicide risk are ‘just a snapshot’

When assessing the link between surroundings and mental health, researchers need to look at people's entire lives, says Dr Helbich.

Research suggests that where we live can affect our mental health but Dr MarcoHelbich, an urban geographer at Utrecht University in the Netherlands, believes these studies only offer a limited snapshot of our lives. Using a smartphone app and register data, he is tracking people through their daily routines and their residential history to see … Read more

Scientists want to use dirty nappies as a source of raw materials

The hardest part about recycling used nappies is opening them.

Thousands of soiled nappies that were destined to clog Italian landfill sites or incinerators are being redirected to a recycling plant that is turning them into streams of high quality raw materials, in a new process that it is hoped will be replicated around Europe. Every day, new parents find themselves sucked into the environmentally … Read more

Seaweed-powered trucks – hope or hype?

The infrastructure for turning seaweed into a sustainable alternative for livestock feed, chemicals and energy is still in its infancy.

Seaweed has long been touted for its potential as a sustainable ingredient for biofuels, green chemicals and biodegradable materials, but scaling up production to industrial levels in a way that maintains its environmental credentials is proving a real challenge for scientists. ‘The potential is there, all the data points to it,’ said Dr Jaap van … Read more

Discarded waste could be a treasure trove of rare metals

Magnetic fields are among the techniques being developed to extract metal particles from slags (stony waste matter).

Miners could soon be scouring mounds of industrial waste to extract rare metals that are needed for products such as electronics, pacemakers, aircraft parts and bicycle gears. Researchers are attempting to figure out how to recover metals that are in limited supply in Europe from material that is often dumped or used in low-grade applications. They … Read more
