Early Earth conditions and the chemistry that led to life were inextricably interwoven. Earth scientists and prebiotic chemists are working together in new ways to understand how life first emerged.

Does the Priming Effect Happen Underwater? It’s Complicated
A new meta-analysis finds evidence that adding fresh organic material can increase decomposition rates, but when and why that happens remain unclear.
Roadside Ditches Are Effective at Nitrogen Removal
Researchers compared the nitrogen removal potential by microbes in ditches that drained forested, urban, and agricultural lands and discovered that roadside ditches are important areas for removing nutrients.
¿Cómo afectará el cambio climático a los Estados Unidos en las próximas décadas?
Un nuevo informe del gobierno de EE. UU. muestra que el clima está cambiando y que las actividades humanas conducirán a muchos más cambios. Estos cambios afectarán el nivel del mar, la frecuencia de las sequías, las precipitaciones severas y más.
Particles at the Ocean Surface and Seafloor Aren’t So Different
Despite occurring on different scales, flux measurements throughout the water column share log-normal probability distributions.
Sinking Fish May Fast-Track Mercury Pollution to the Deep Sea
Isotopic analysis indicates that mercury found in deep-sea organisms may have an origin in carrion from near the surface.
El Zooplancton Gelatinoso Transfiere Una Cantidad Significativa de Carbono a las Profundidades del Océano
Un nuevo estudio muestra que las medusas y las salpas marinas no reciben el crédito que merecen por su papel en el ciclo del carbono en el océano.
Water Stress Controls the Capacity of the Terrestrial Carbon Sink
Despite increased photosynthetic activity at northern latitudes in recent decades, plant productivity in tropical zones suffers because of water limitations.
Acidifying Oceans Could Get Help from Kelp
Forests of fast-growing kelp influence the chemistry of the water in which they live. A new study evaluates their potential to ameliorate ocean acidification in sensitive coastal ecosystems.
