Did a Chaotic Climate Drive Human Evolution?
A new 620,000-year climate record from East Africa reveals dramatic swings between wet and dry conditions that may have influenced human evolution.
Isótopos de criptón proporcionan nuevos indicios sobre el pasado de los planetas
Para determinar cómo los elementos cruciales para el desarrollo de la vida llegaron a la Tierra, los científicos estudian los gases nobles. Actualmente, métodos mejorados traen consigo nuevos indicios a partir del criptón, el gas noble más enigmático.
Not Your Childhood Water Cycle
The USGS just debuted a complete remaking of the water cycle diagram—with humans as headliners.
California Quakes Mysteriously Preceded by Shifts in Earth’s Magnetic Field
When the next big earthquake strikes somewhere around the world, it will arrive without warning, destroying infrastructure and putting lives at risk. Yet for days leading up to the event, titanic geological forces will already be at work, warping the crust in subtle ways that could, in theory, predict the coming catastrophe.
Dynamics of Ocean Worlds Likely Controlled by Their Rotation
New simulations suggest that subsurface oceans on icy moons with small natural Rossby numbers may be dominated by rotational effects.
A Lidar’s-Eye View of How Forests Are Faring
Success in Yosemite is driving the wider use of lidar surveys to support forest health and wildfire resilience, study wildlife habitats, and monitor water resources.
Is Earth’s Core Rusting?
If subduction carries hydrous minerals deep into Earth’s mantle, they may “rust” the iron outer core, forming vast sinks of oxygen that can later be returned to the atmosphere.
A Climate Mystery Warns Us to Heed the Unknown
Methane, a potent greenhouse gas, has been rising in the atmosphere at an accelerating rate since 2007. But the cause of the acceleration remains unknown.
Exploring Subduction Zone Geohazards on Land and at Sea
A new initiative is bringing together scientists to address fundamental questions about subduction zone geohazards, using the latest advances in observation technology and computational resources.
Cuando los ríos están contaminados, las inundaciones son solamente el primer problema
A medida que las inundaciones aumentan en frecuencia e intensidad, los productos químicos enterrados en los sedimentos de los ríos se convierten en “bombas de tiempo” que esperan activarse.
