A new study from University of Toronto Engineering researchers points to practical strategies to prevent deaths from opioid poisoning by optimizing the distribution of naloxone kits. 

In a paper published in the Canadian Medical Association Journal, Professor Timothy Chan and his team showed that placing naloxone kits in transit stations could help ensure that these potentially life-saving tools are present where they are most needed.

Full Waveform Inversion (FWI) is capable of finely characterizing the velocity structure, anisotropy, viscoelasticity, and attenuation properties of subsurface media, which provides critical constraints for scientific problems such as understanding the Earth’s internal structure and material composition, earthquake preparation and occurrence, and plate motion and dynamic processes. In recent years, with advancements in high-performance computing platforms, improvements in numerical methods, and the cross-integration of multidisciplinary, FWI has demonstrated broad application prospects in deep underground structure exploration, resource and energy exploration, engineering geophysics, and even medical imaging. In this paper, we provide a comprehensive review and analysis of the development of the FWI method, addressing its current challenges, identifying key issues, future directions, and potential research areas in the theory, methodology, and application of high-resolution FWI imaging. The related findings were published in SCIENCE CHNIA: Earth Science, 68(2): 315‒342, 2025.

Existing tax policies during the energy transition from fossil fuels to renewable sources will lead to major energy injustices and skewed priorities, new research published in Climate Policy shows.
