Researchers at the University of Waterloo are working with government, academic and industry partners to tackle several challenges in Ontario’s agricultural sector, including short growing seasons, rising production pressures and crops that can fail long before anyone sees warning signs.

Lead contamination in soil tracked inside homes can cause dangerous indoor lead dust levels even in residences with no interior lead-based paint, according to researchers with the Rutgers Environmental, Occupational and Health Sciences Institute in collaboration with community scientists: members of the general public who participate in data collection under the direction of scientists.

The Southern Ocean covers almost a third of the world’s ocean surface and connects the basins of every other major ocean, with unforgiving conditions that make research difficult.

Marine carbon dioxide removal (CDR) has advanced significantly, with growing research activity, technological development, private-sector involvement, and movement toward field testing, but major questions remain about whether these approaches can remove carbon dioxide at meaningful scales, how that removal can be reliably measured and verified, potential environmental effects, and how marine CDR should be governed, says a new digital report from the National Academies of Sciences, Engineering, and Medicine.

The Arctic is warming at an accelerating pace.

The effects of a meager mountain snowpack across the Upper Colorado Basin in winter 2025-2026 had made their way downstream to Lake Powell by summer. 

Tests in university classes show that simple, low-cost systems can remove airborne particles with little disruption from fan noise.

Documenting the seasonal fate of these tiny marine organisms is a step toward understanding how ecosystems in the world's fastest-warming region may change as ice recedes.

A new study found more than half of the city’s bike-share trips replace car trips, with each bike reducing annual CO2 emissions by up 120 kilograms (kg) per year.

In a discovery as broad and far-reaching as the Big Muddy itself, a new, Yale-led study says farmers along the Mississippi River Basin are storing more carbon dioxide (CO2) in the soil than they are emitting when they add limestone to their fields, an agricultural practice known as “liming.”
