Azara’s owl monkeys, a small primate species found in South America, are heavier today than those that lived a quarter-century ago, and evidence suggests that rising temperatures might have driven the weight gain, according to a Yale-led study of a wild population.

Alaska’s Cook Inlet was home to nearly 1,300 beluga whales in the late 1970s, but today the population hovers around 300.

As climate change intensifies extreme weather and environmental conditions across the country, about 65% of U.S. adults are concerned that climate change will negatively affect their personal health, according to a new study published in Health Affairs Scholar.

For her research on fungi that can degrade plastic and sunscreen, Vera Wang, a senior at Kaiser High School, won in multiple categories at the 2026 Hawaiʻi State Science & Engineering Fair for her research conducted in Anthony Amend’s lab at the University of Hawaiʻi at Mānoa.

A water-based formulation developed at the University of Waterloo using nanotechnology is both greener and more effective than conventional methods for delivering agricultural pesticides.

Penn State’s Beescape tool is gaining a new feature that allows users to download county-specific lists of pollinator-attractive plants, offering a more localized approach to improving pollinator habitats across Pennsylvania.

For the past several years, Penn State geoscientist Sarah Ivory and her students have been among a team of scientists scaling the East African Rwenzori Mountains, collecting sediment core samples from lakes formed at the end of the last ice age as glaciers began receding in the region some 12,000 years ago.

Even as temperatures rise on Earth’s surface and in the lower atmosphere, the planet’s upper atmosphere has cooled dramatically.

New research by a collaboration of UK‑based scientists has revealed that common indoor and outdoor air pollutants can alter both brain and respiratory function within just four hours of exposure, offering key insights into how air pollution impacts brain health and may contribute to dementia risk.

The potent pollution from so-called “megaconstellation” satellite systems launched en masse into space since 2019 will account for nearly half (42%) of the total climate impact of space sector pollution by the end of the decade, finds a new study led by UCL researchers.
