When spring arrives and the heating season comes to an end, keeping warm becomes less of an issue. 

Researchers combine machine vision and segmentation techniques into a tool to monitor urban plant health at the individual leaf level.

A “weekend warrior” approach to physical activity — getting 150 minutes of moderate-to-vigorous physical activity over one to two days instead of throughout the week — improved health and lowered the risk of death, finds a new study in the Journal of the American Heart Association.

Designed by University of Missouri researchers, the device includes AI technology to detect potential heart problems with over 90% accuracy, making it a promising tool for at-home monitoring.

A single severely dry winter temporarily, but dramatically, altered the ranges of three fishes — Chinook salmon, coho salmon, and steelhead trout — in California’s northern waterways.

As global temperatures warm, the Southern Ocean – between Antarctica and other continents – will eventually release heat absorbed from the atmosphere, leading to projected long-term increases in precipitation over East Asia and the Western U.S., regardless of climate mitigation efforts.

Nuclear power plants keep their waste close by.

Heavy rainfall in Queensland sent floodwaters sweeping across vast stretches of the Australian outback in late March 2025.

In 2025, summer sea ice in the Antarctic tied for the second-lowest minimum extent ever recorded in the 47-year satellite record, according to NASA and the National Snow and Ice Data Center (NSIDC).

A new study led by McGill University researchers indicates that humpback whales in the southeastern Pacific combine real-time environmental cues with their memories of conditions in their Antarctic feeding grounds to determine when to embark on their annual 10,000-kilometre journey.
