Just how many species of bees live in Ohio? Based on other states, estimates land between 400 and 450. Until recently, there hasn’t been a way to be sure.

A new study published in the Proceedings of the National Academy of Sciences (PNAS) provides scientists with a powerful new tool for monitoring and predicting tectonic activity deep beneath the seafloor at mid-ocean ridges—vast underwater mountain chains that form where Earth’s tectonic plates diverge.

A team of researchers led by the University of California San Diego has discovered a new way to make yeast cells more efficient “factories” for producing valuable plant compounds.

Electronic waste is piling up around the world at a rate that far outpaces recycling efforts, partly because it’s so costly and time-consuming to recover useful materials from discarded gadgets.

Two large-payload unmanned aircraft have joined the fleet of the University of Alaska Fairbanks’ drone industry development program.

A microscopic organism that thrives in the most inhospitable environments on the planet could be a serious weapon against costly and dangerous microbes, including one that decimates apple and pear orchards.

Kelp shows great promise for improving soil health and crop production in Alaska.

Installing green infrastructure in residential areas can prevent stormwater from flooding sewer systems and significantly curb heavy metal pollution, suggests a new study.

Montreal’s methane emissions are unevenly distributed across the island, with the highest concentrations in the city’s east end, McGill researchers have found. The worst polluters include the city’s largest snow dump, which emits methane at levels comparable to the city's current and former landfills, and natural gas leaks.

The leaves have turned in the northern hemisphere and the Lower Mainland is seeing its blaze of glory.
