A push to end a fractured approach to post-fire contamination removal
The patchwork efforts to identify and safely remove contamination left by the 2025 Eaton and Palisades fires have been akin to the Wild West. Experts have given...
Aerial lidar mapping can reveal archaeological sites while overlooking Indigenous peoples and their knowledge
Picture an aircraft streaking across the sky at hundreds of miles per hour, unleashing millions of laser pulses into a dense tropical forest. The objective: map...
New satellite method maps 'creeping drought' in Canada's mountain snow
Researchers at Concordia have developed a new method of measuring the amount of usable water stored in snowpacks. The comprehensive technique, known as snow wat...
To reduce CO₂ emissions, policy on carbon pricing, taxation and investment in renewable energy is key
A new study evaluating climate policies in 40 countries over a 32-year period finds that carbon pricing and taxation—combined with investments in renewable ener...
Study finds imported ozone blunted Europe, US gains from NOx cuts
In North America and Europe, emissions of ozone precursors such as nitrogen oxides (NOx) and volatile organic compounds (VOCs) declined by half between 2000 and...
RNA droplets may have accelerated prebiotic Earth's development of complex molecules
The origin of life from Earth's primordial chemistry has long fascinated and perplexed us. Generations of scientists have endeavored to understand how complex b...
Freestanding 3D MXene structures push the limits of microscale devices
In a breakthrough that could power next-generation electronics, sensors, and energy storage devices, CMU engineers have developed a fabrication technique that a...
Direct imaging captures the crystalline vibrations of a supersolid made of atoms and light
The 20th century was marked by the discovery of exotic states of matter. First, liquid helium was observed to flow without friction at extremely low temperature...
New chemi-mechanical process removes pigments and restores properties in recycled plastics
Researchers in Worcester Polytechnic Institute's Department of Chemical Engineering and at the University of Akron have published research in Chemical Engineeri...
Silica nanocomposite can generate biocides on demand
A surface capable of responding to chemical signals generated by microorganisms and automatically producing biocidal substances—this is not a futuristic vision,...
Biodegradable polymers used to develop eco-friendly, high-performance gas sensors
Air pollutants like nitrogen dioxide (NO2), primarily produced during fossil fuel combustion, pose a serious concern for human health, contributing to respirato...
Growing meltwater reservoirs—glacial lakes are both a resource and a habitat worthy of protection
Should growing glacial lakes be used for energy production and water supply—or remain protected as ecologically valuable systems? A research team from the Unive...
