We found a way to turn urine into solid fertiliser – it could make farming more sustainable

If rolled out worldwide, our method could replace a quarter of all the synthetic nitrogen fertiliser used in agriculture.

A few heavy storms cause a big chunk of nitrogen pollution from Midwest farms

New research shows that one-third of yearly nitrogen runoff from Midwest farms to the Gulf of Mexico occurs during a few heavy rainstorms. New fertilizing schedules could reduce nitrogen pollution.

Drive-throughs are busier than ever during the pandemic – but they're hotspots for air pollution

Staff and customers with underlying health conditions are likely to be most at risk at drive-through windows.

Rainy days can send nitrogen runoff to rivers

Heavy rain events, which happen just a few days each year, have an outsize role in sending nitrogen runoff into waterways, computer modeling indicates.

Routine gas flaring is wasteful, polluting and undermeasured

Flaring, or burning, waste gas from energy production has sharply increased over the past decade. It wastes usable fuel, pollutes the air, and helps drive climate change.

COVID-19 shutdowns are clearing the air, but pollution will return as economies reopen

From Nairobi to Los Angeles, pandemic lockdowns have cleared pollution from the skies. But those blue vistas may be temporary, and shutdowns aren't slowing climate change.

Fishing targets the ‘super-urinators’ that ecosystems need

Certain fish are super-urinators, meaning that they contribute more nitrogen to the ecosystem. Unfortunately, they're also prize catches.
