¿Pueden los microorganismos prosperar en la atmósfera terrestre o simplemente sobreviven allí?
Un enfoque de modelización ascendente podría acercar a los científicos a la comprensión de las comunidades de microbios en la atmósfera.
Can Microorganisms Thrive in Earth’s Atmosphere, or Do They Simply Survive There?
A bottom-up modeling approach could bring scientists closer to understanding communities of microbes in the atmosphere.
Simulating the Journey of Pollen in the Atmosphere
A new study couples an emission and transport scheme of pollen from vegetation, and explores pollen’s evolution in different atmospheric conditions and its impacts on clouds and precipitation.
UV Radiation Contributed to Earth’s Biggest Mass Extinction
To find the first direct evidence of heightened UV radiation during the end-Permian mass extinction, researchers turned to chemical evidence preserved in pollen grains.
Ancient Nile Tributary May Have Aided Pyramid Construction
Pollen from sediment cores shows that a now dry channel cutting through Giza was once a flowing waterway that Egyptian pyramid builders could have used to transport supplies.
Fiona Lo: A “Really Long, Convoluted Path” to Health
Lo uses her background in atmospheric sciences to forecast pollen concentrations.
Chicxulub Impact Changed Tropical Rain Forest Biodiversity Forever
Sixty-six million years ago, an asteroid reset most of life on Earth. But without this catastrophic event, the composition of neotropical rain forests wouldn’t be the same.
Bat Guano Traces Changes in Agriculture and Hurricane Activity
Researchers hiked and rappeled into two caves in Jamaica to collect over 40 kilograms of excrement.
