In a happy accident, scientists found a potential solution to an atmospheric chemistry mystery. Their findings could be a missing piece in the iodine cycle and in atmospheric models.
A new study reveals the atmospheric paths of storm events that can deliver a decade’s worth of rain in a few hours to the Atacama Desert.
In experiments conducted in Biosphere 2, invasive buffelgrass weathers higher temperatures and drought conditions better than its native brethren.
Bacteria can speed up the growth of biocrust-forming organisms in nurseries, providing more material for restoration of degraded dryland soil.
Dunes may morph or creep in new directions in a warming world.
Hand axes, hippo bones, and a stack of ancient lake beds show that arid Arabia experienced intervals of humid weather, spurring pulses of human migration over the past 400,000 years.
Without water, photosynthesis shuts down. To survive dry spells, desert microbes scavenge traces of hydrogen from the air and burn it for energy. Some even use hydrogen to fuel carbon fixation.
A fence spans Australia’s Strzelecki Desert, keeping dingoes out of the southern side. Drone and satellite technology have illustrated how removing this top predator changes vegetation growth.
Scientists studying a cyanobacterium isolated from rock samples in the Atacama Desert found out how the bacteria extract water to live. Their results may help identify likely sites for life on Mars.
Large-scale irrigation programs have triggered giant, slow-moving landslides in arid valleys, leading to the destruction of both traditional and modern farmland.
