When polymers prove resistant to recycling, new chemical techniques can do the job of breaking them down for reuse

Modern industry has made great strides in turning trash into tomorrow’s new products, but the process is still a long way from perfect. New technologies can help. Plus, updates on chemical recycling, design for recycling and dirty recycling.

Epidemics of forest-felling diseases are on the rise thanks to globetrotting pathogens that slip through even the best defenses. To prevent further losses, scientists are turning to high-tech surveillance and detection, even canine noses.

The controversial technology of reflecting sunlight away from the planet could help blunt the worst impacts of climate change

Glaciologists dream of a cold-storage vault in Antarctica to preserve key samples of the paleoclimate

Where other species succumbed, the killifish survived contaminated habitats. It’s a finding that could help researchers understand environmental risk factors for humans.

Dredging rivers, filling in wetlands and other human acts of engineering have shifted coastal ebbs and flows worldwide. Add rising sea levels, and the threat of storm surges and floods will worsen in some places.

Policymakers, entrepreneurs and farmers are increasingly looking to soils in their fight to slow climate change

Climate change is aggravating the seasonal burns that Australia has always known. They won’t be snuffed out, but new ecological strategies may help.
