These inland waters &quot;breathe&quot; oxygen, just like we do. But a new study led by Utrecht University researchers shows that we've been suffocating them during the last century, an era also known as the Anthropocene. The research, published today in Science Advances, reveals that the way oxygen is produced and used in inland waters has dramatically changed since 1900. The culprit? Human activities.</description> <link>https://phys.org/news/2025-04-oxygen-inland-human-blame.html</link> <category>Earth Sciences Environment </category> <pubDate>Fri, 04 Apr 2025 14:00:01 EDT</pubDate> <guid isPermaLink="false">news662984761</guid> <media:thumbnail url="https://scx1.b-cdn.net/csz/news/tmb/2025/inland.jpg" width="90" height="90" /> </item> <item> <title>Battle of the sex chromosomes: How competition affects X vs. Y sperm fitness</title> <description>In evolutionary terms, fitness is defined as an organism's ability to survive and reproduce its genes into the next generation.
