Climate disclosure gives Canadian companies an edge with European investors, new research shows‎

Canadian companies that disclose their climate-related risks and impacts have a considerable advantage over those that don't when it comes to attracting financing from European institutional investors, according to our recent report for the Institute for Sustainable Finance at Queen's University.

Floating-electron catalyst withstands week in air while making ammonia under milder conditions‎

A surface electrene, BaSiN2:O, developed by researchers at Science Tokyo enables efficient ammonia synthesis under mild conditions while overcoming the long-standing air instability of electrene materials. Synthesized by doping barium silicon nitride with oxygen, the material forms a stable layer of freely floating electrons on its surface.

Carbon storage could curb more than 90% of AI data center emissions, study finds‎

As artificial intelligence accelerates demand for computing power across the U.S., a new study co-authored by Hon Chung Lau, adjunct professor in the Department of Chemical and Biomolecular Engineering at Rice University and founder of Low Carbon Energies LLC, has found that carbon capture and storage could play a major role in limiting the climate impact of data centers.

Scientists uncover molecular mechanism linking water-saving irrigation to cadmium accumulation in rice‎

Water-saving irrigation practices, including intermittent irrigation, are essential for sustainable rice cultivation amid growing freshwater shortages. However, periodic drainage creates aerobic soil conditions that drastically boost cadmium (Cd) bioavailability, leading to severe grain Cd enrichment. Disentangling the relationship between water conservation and high grain Cd has been a critical challenge for rice breeders and soil scientists worldwide.

AI-powered electronic nose can distinguish tens of thousands of odors‎

A research team has presented a roadmap for developing an "artificial olfactory system" that detects odors like the human nose and analyzes them using artificial intelligence (AI) by leveraging metal-organic frameworks (MOFs). The team systematically organized and reviewed key research trends in electronic nose technology, from MOF material design to sensor implementation and AI-based odor pattern recognition. The research was led by Hyuk-Jun Kwon's in the Department of Electrical Engineering & Computer Science of Daegu Gyeongbuk Institute of Science and Technology. The work is published in the journal Progress in Materials Science.

Where mainshocks strike may explain earthquake size patterns better than timing, data suggests‎

Japan is well known for its large earthquakes, but not all regions show the same patterns of earthquake activity. One way to understand which places tend to experience large or small earthquakes is the b-value, a key statistical measure long used by researchers to understand seismicity and assess earthquake occurrence patterns.

Six massive landslides discovered on icy Pluto‎

Scientists have detected evidence of landslides on Pluto for the first time. A paper published in the journal Icarus reports that images taken by the New Horizons spacecraft during a flyby revealed six large landslides in three impact craters.

New imaging method reveals how electric fields reshape ferroelectric materials‎

New research is shedding light on longstanding debates over the behavior of ferroelectric materials when those materials are exposed to electric fields. The findings stem from the use of a novel technique that allows researchers to observe the real-time behavior of domain walls in ferroelectric materials as they are "poled" and "depoled."
