In the aftermath of historically severe wildfires in 2020, a study of Cascade Range watersheds found that stream vertebrates are doing surprising well, highlighted by flourishing fish populations.

A new study co-led by the University of Oxford has found that global aviation emissions could be reduced by 50-75% through combining three strategies to boost efficiency: flying only the most fuel-efficient aircraft, switching to all-economy layouts, and increasing passenger loads. Crucially, the study shows that around a 11% reduction in global aviation emissions is achievable immediately, by using the most efficient aircraft that airlines already have more strategically on routes they already fly.

An international team of astronomers led by Canadian researchers has found something the universe wasn’t supposed to have: a galaxy cluster blazing with hot gas just 1.4 billion years after the Big Bang, far earlier and hotter than theory predicts.

As fires burn the landscape, they spew airborne gases and particles, though their impact on air pollution might be underestimated. 

Australia’s beloved dolphin populations face growing pressures from environmental changes and human activity, increasing the need for reliable, accessible and non-invasive tools to monitor their health and support conservation and management.

UC Santa Cruz researchers show how vessel-tracking data mirrored tuna roaming beyond their typical territory due to unusually warm ocean temperatures.

As these events become more common at midlatitudes, a phenomenon called an atmospheric inversion will determine how long they last.

Stanford Medicine scientists and their colleagues created the first artificial intelligence model that can predict more than 100 health conditions from one night’s sleep.

Hundreds of Norwegian hydropower plants threaten fish and bottom-dwelling animals by exposing them to water that is oversaturated with air. 

Tiny, sun-powered organisms found in freshwater pools could soon fuel Hawaiʻi’s sustainable future.
