Proposed methods of removing toxic ‘forever chemicals’ from water have either only trapped the chemicals or broken them down. A new study has demonstrated a method that does both effectively. And it's quick and cheap.

This serene gap between Pyrenees mountains becomes abuzz with flying insects each year, as they journey across Europe. We may not always like to live with them, but we can't live without them – so paths like this are critical for all life on Earth.

A new solution from Cambridge University could recycle both concrete and steel at the same time, by throwing old concrete into steel-recycling furnaces. If done using renewable energy, the process could make for completely carbon-zero cement.

For the first time, scientists from across North America have formed a clear picture of Alaska's 'rusting' rivers and streams, tracking 75 areas in the remote Brooks Range that are flushed with the bizarre hue so bright it's even visible from space.

A new biodegradable plastic embedded with spores of plastic-eating bacteria manages to break down 90% of the material after five months in landfill. Weirdly, this actually made the plastic tougher and stronger during use.

It's super-sustainable, easily made and nutrient-dense. And it puts all other food production to shame. Now, the first air-protein factory is open. It's the food of the future, and soon a $100 million industry – but will you be putting it on your plate?

Sales of vinyl records have been on the rise for a few years now, but the plastic used to create them is bad news for the enviro-conscious listener. A UK startup is hoping to change that by pressing for plant-based alternatives.

Korean scientists have taken muscle and fat stem cells from cows and transplanted them into grains of rice. The end result is a new, high-protein food that should be cheap, environmentally friendly, and useful for famines, military or space travel.

Researchers have developed a simplified, sustainable method of converting sewage sludge from wastewater treatment into high-value activated carbon that can be used in a wide range of industrial and residential applications.

Swiss researchers are working on an environmental monitoring robot named Avocado that's been inspired by abseiling spiders. The fruit-shaped bot uses a winch and rotors to lower itself through the canopy and gather data on life in the treetops.

A new photography competition has released its first batch of winners and finalists. A portrait of a playful sea lion has won the inaugural Nature Photography Contest, which showcases animals, plants, landscapes and human impact on the environment.

Every year, countless stunning images are submitted to photography competitions around the world. From cosmic structures to microscopic marvels and everything in between, here is a snapshot of the most awe-inspiring photographs of 2023.
