More Than Half the World’s Ocean Surface Is Getting Greener
Advances in data analysis help researchers spot shifting ocean colors, which could be associated with climate change.
Air Flow Dynamics in Wet Soils: Challenges and Knowledge Gaps
Modeling air flow in wet porous media relies on quantifying the combined role of fluid and media properties and flow dynamics on the microscale displacement mechanisms and macroscale unstable flow.
The Science We Need to Assess Marine Carbon Dioxide Removal
As companies begin selling credits for marine carbon dioxide removal in largely unregulated marketplaces, scientists must develop standards for assessing the effectiveness of removal methods.
Harpy Eagles Concentrate Precious Nutrients in the Amazon
Amazon soils are usually low in the nutrients that plants covet, but harpy eagles can create local hot spots with their poop and prey.
(Probablemente) No podremos decir si Marte tiene vida
Los equipos de última generación no siempre pueden identificar la vida que habita en los lugares más parecidos a Marte en la Tierra, lo que hace que los científicos se pregunten cómo se se podría hacer mejor en el Planeta Rojo.
Hypoxia Affects One in Eight Rivers Worldwide
A global study found dangerously low levels of dissolved oxygen in rivers around the world. The true prevalence of hypoxia is probably even higher.
We (Probably) Can’t Tell Whether Mars Has Life
State-of-the-art equipment can’t always identify life inhabiting the most Mars-like spot on Earth, leaving scientists wondering how to do better on the Red Planet.
喷气推进的被囊动物在海洋碳循环中的作用
新研究表明,广泛分布的胶质浮游动物的大量繁殖,连同它们的粪便、每日的垂直迁移和它们的尸体一起,增加了海洋的碳输出。
Jet-Propelled Tunicates Pump Carbon Through the Oceans
New research reveals that blooms of the widespread gelatinous zooplankton—along with their feces, daily vertical migrations, and carcasses—increase marine carbon export.
