The emerald ash borer has killed more than 150 million trees in the US in the last decade and is a potential threat to Europe’s forests.

Trade and climate change increase pest threat to Europe’s forests

Europe’s forests face a growing threat from pests due to global trade and climate change, but scientists are developing techniques that can give an early warning of infestations to help combat damaging insects and diseases.

Q&A: Plate tectonics is fundamental to understanding Earth’s evolution – but big questions remain

The division of the Earth’s surface into seven major mobile plates is fundamental to our planet’s uniqueness, creating a habitable environment and possibly the conditions under which life itself originated. The theory of plate tectonics is 50 years old, but there are many puzzles left to answer, says Dr Kate Rychert, who studies the geology at the bottom of the Atlantic Ocean.

Air pollution standards currently focus on the mass concentration of particles smaller than 10 micrometres in diameter (PM10) or smaller than 2.5 micrometres (PM2.5). Image credit - Panek/Wikimedia, licenced under CC BY-SA 4.0

Size matters in air pollution – but it’s not enough

Current regulations on air pollution mainly focus on the mass of particles of a particular size range in a sample, and this has been used as a marker for their threat to human health. But these air quality standards do not address the medical implications of the very smallest particles – nor other attributes that may be damaging, such as their chemical makeup.

Understanding why trees are dying may be key to locking up carbon

Rising tree deaths may be reducing the ability of many forests worldwide to lock up carbon by pulling in greenhouse gases from the air. To properly grasp what this means for carbon budgets, scientists need to solve the puzzle of why trees are dying – and how they respond to change.

‘Four times more toxic’: How wildfire smoke ages over time

Enormous plumes of smoke thrown into the atmosphere by uncontrolled wildfires may be affecting the health of people living hundreds of miles away.

Dairy waste is being turned into bioplastics and plant food

Dairies in Europe are major economic drivers in rural areas, but they produce significant waste from cleaning and processing. Wastewater and milk residue, which are typically disposed of, are now being turned into new products such as phosphate-rich fertiliser and bioplastics.

Air pollution affects brain development - but when does the damage start?

The emergency rooms in Barcelona were collapsing under the pressure. Hundreds of patients were arriving in desperate need as they struggled to breathe, while intensive care units struggled to cope with the sudden influx of respiratory problems. Epidemiologists scrambled to trace the source of the outbreak.

Quiet and green: Why hydrogen planes could be the future of aviation

Today, aviation is responsible for 3.6% of EU greenhouse gas emissions. Modern planes use kerosene as fuel, releasing harmful carbon dioxide into the atmosphere. But what if there was another way?

How Europe’s city façades and pavements are being used to harvest clean energy

Building façades and pavements in Dutch and Italian cities are being turned into smart, energy-harvesting surfaces and equipped with sensors to power, heat and cool spaces and even monitor roads.

Making coal from food waste, garden cuttings – and even human sewage

Food waste, garden cuttings, manure, and even human sewage can be turned into solid biocoal for energy generation, and, if scaled up, could help match the industrial demand for carbon with the need to get rid of organic waste and reduce greenhouse gas emissions.
