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.

Global Aviation Emissions Could be Halved Through Maximising Efficiency Gains, New Study Shows
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...
Earliest, Hottest Galaxy Cluster Gas on Record Could Change our Cosmological Models
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.
Fires Could Emit More Air Pollution Than Previously Estimated
As fires burn the landscape, they spew airborne gases and particles, though their impact on air pollution might be underestimated.
Melting Glaciers Top the List
Climate change, trust in science and health were among the most popular topics covered by UZH media releases and articles in 2025.
Drone Monitoring Helps Dolphins
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.
Wildfires are polluting the air far more than thought
Scientists have discovered that wildfires release far more air-polluting gases than previously estimated. Many of these hidden emissions can transform into fine particles that are dangerous to breathe. The study shows wildfire pollution rivals human-made emissions in some parts of the world. This helps explain why wildfire smoke can linger...
Breakthrough lets scientists watch plants breathe in real time
Scientists have created a new way to watch plants breathe—live and in high definition—while tracking exactly how much carbon and water they exchange with the air. The breakthrough could help unlock crops that grow smarter, stronger, and more drought-resistant.
11,000-year-old dog skulls reveal a hidden origin story
Dogs began diversifying thousands of years earlier than previously believed, with clear differences in size and shape appearing over 11,000 years ago. A massive global analysis of ancient skulls shows that early dogs were already adapting to different roles in human societies. This challenges the idea that dog diversity is...
This simple math trick could transform earthquake science
Earthquakes happen daily, sometimes with devastating consequences, yet predicting them remains out of reach. What scientists can do is map the hidden layers beneath the surface that control how strongly the ground shakes. A new approach speeds up complex seismic simulations by a factor of about 1,000, making risk assessments...
