While talks on an international plastics treaty remain deadlocked, California is starting a process that could lead to microplastics regulation. On Oct. 1, the state will add microplastics to a list of substances that evidence suggests may be harmful to people or the environment and are candidates for increased regulation.
A new study found that rates of intentional substance exposures at school reported to U.S. poison centers increased substantially among elementary- and middle-school-aged children from 2000 through 2024, while high-school-aged adolescents continued to experience the highest rates of serious medical outcomes and hospital admissions.
Wildlife researchers have found that both recreation and roads affect wolverine populations in Canada's Rocky Mountains and Columbia Mountains.
Landing on a moving target is a challenge for all flying animals. For bumblebees, a flower swaying in the wind creates an erratic landing pad. Reaching it means matching its sideways motion while continuing to face it. When the bee turns in flight, its view of the flower changes, which complicates the feat.
Evolution is driven by changes in DNA that sometimes promote adaptation, altering traits like disease resistance or reproduction. Often, these changes are minuscule, modifying a single letter in the DNA code—somewhat like altering a single letter on one page of a long book.
Food in Senegal is mostly grown on small-scale, rain-dependent farms, leaving much of the population vulnerable to climate shocks, according to the World Food Programme. However, satellite crop-mapping technologies designed to monitor the impact of climate on farming are largely beyond the reach of the West African country.
Japan's population peaked around 2008 and has been steadily declining since. But construction hasn't stopped.
A study based on publication data traces how researchers moved within Ukraine and across borders between 2009 and 2022, with conflict-affected regions losing scholars while others became increasingly important destinations. These shifts were already underway after Russia illegally annexed Crimea and fighting began in the Donbas in 2014, underscoring that scholarly mobility during conflict cannot simply be understood as a matter of free choice.
