Industrial forests, packed with evenly spaced trees, face nearly 50% higher odds of megafires than public lands. A lidar-powered study of California’s Sierra Nevada reveals how dense plantations feed fire severity, but also shows that proactive thinning could prevent forests from collapsing into shrubland ecosystems.
Study Finds Montreal Cycling Infrastructure Doesn’t Match Demand
Bike lanes, BIXI stations and other micromobility infrastructure make up just two per cent of Montreal’s street space – even in neighbourhoods where cycling demand would justify more – according to a new study by McGill University researchers.
Ash Dieback is Triple Whammy for Net Zero Plans
Ash dieback and other tree diseases are resulting in significantly more greenhouse gas emissions than previously thought because a large amount of carbon is escaping from woodland soils, a study has found.
2022 Pacific Volcano Eruption Made a Deep Dive into Alaska
Atmospheric waves from a massive 2022 South Pacific volcanic eruption created seismic waves that penetrated Earth to at least 5 kilometers in Alaska, creating an opportunity to employ an unusual method of peering into the state’s deep subsurface.
Protected seas help kelp forests bounce back from heatwaves
Kelp forests bounce back faster from marine heatwaves when shielded inside Marine Protected Areas. UCLA researchers found that fishing restrictions and predator protection strengthen ecosystem resilience, though results vary by location.
Scientists unlock the gene that lets bearded dragons switch sex
Two independent research teams have unveiled near-complete reference genomes of the central bearded dragon, a reptile with the rare ability to change sex depending on both chromosomes and nest temperature. Using next-generation sequencing technologies from China and Australia, the projects uncovered the long-sought genetic basis of sex determination in this...
Tiny microbes may secretly rewire the brain before birth
MSU researchers discovered that microbes begin shaping the brain while still in the womb, influencing neurons in a region critical for stress and social behavior. Their findings suggest modern birth practices that alter the microbiome may have hidden impacts on brain development.
Reusable ‘Jelly Ice’ Keeps Things Cold — Without Meltwater
No matter whether it’s crushed or cubed, ice eventually melts into a puddle — but an alternative called jelly ice doesn’t.
Texas Study Reveals Heat Waves Can Cause More Polluted Air
Heat waves are becoming more common, severe and long-lasting.
Years After an Earthquake, Rivers Still Carry the Mountains Downstream
On May 12, 2008, the magnitude 7.9 Wenchuan Earthquake shook central China, its destructive tremors spreading from the flank of the Longmen Shan, or Dragon's Gate Mountains, along the eastern margin of the Tibetan Plateau.
