Garbage-collecting aqua drones and jellyfish filters for cleaner oceans

It is estimated that more than 150 million tonnes of plastics have already accumulated in the world's oceans.

A Roomba-like ocean trash collector modelled on a whale shark and a microplastic filter made from jellyfish slime could prevent litter from entering our oceans and help tackle a growing problem that poses threats to wildlife, deters tourists and impacts on coastal economies. The cost of sea litter in the EU has been estimated at up to … Read more

Light pollution is altering plant and animal behaviour

Light pollution can be problematic for animals like the Cory's shearwater.

by Gareth Willmer You could call it fatal attraction. Drawn by artificial lights in our brightening night-time world, animals find their lives in peril. Fledgling birds disorientated by lights can collide with human structures on the ground and then get hit by cars, or become more vulnerable to predation, starvation or dehydration. Or newly hatched … Read more

Climate sensitivity – reducing the uncertainty of uncertainty

New research aims at making climate change prediction more accurate.

Global warming is a reality – but just how bad will it be? A study published in January 2018 claims to halve the uncertainty around how much our planet’s temperature will change in response to rising carbon dioxide (CO2) levels, potentially giving governments more confidence to prepare for the future. The results suggest that, when it … Read more

Warmer, saltier polar water could change global ocean currents

When ice shelves melt, they dump freshwater into the sea which lightens the salty water.

Melting ice shelves are changing the ocean’s chemistry at the South Pole and the result could be a change in global currents and increased glacial melt, according to scientists who are creating maps to feed into climate change models. At the North and South Poles, cold dense water sinks, powering the so-called global ocean conveyor belt, … Read more

Turning landfill into energy

Landfill is both ugly and polluting. But a new breed of technology promises to make it a thing of the past, transforming a huge portion of landfill material into clean gas. It’s thanks to a process called gasification, which involves turning carbon-based materials into gas by heating them to a high temperature but without burning … Read more

Ancient farming techniques could help mitigate climate change

Geographically defined products such as Parma ham help to assess the social and cultural value of a landscape.

High technology is being deployed to uncover long-forgotten irrigation systems and other features concealed in landscapes that farmers developed hundreds of years ago to nurture their land. By studying landscapes of the past and how they’re used today, scientists can draw on Europe’s cultural heritage to help tackle challenges such as climate change and rural exodus. Professor José … Read more
