'Pack ice' tectonics reveal Venus' geological secrets

A new analysis of Venus' surface shows evidence of tectonic motion in the form of crustal blocks that have jostled against each other like broken chunks of pack ice. The movement of these blocks could indicate that Venus ...

Extreme greenhouse effect heated up the young Earth

Very high atmospheric CO2 levels can explain the high temperatures on the still young Earth three to four billion years ago. At the time, our Sun shone with only 70 to 80 percent of its present intensity. Nevertheless, the ...

A deep dive into organic carbon distribution in hadal trenches

Hadal trenches are one of the ocean's most extreme and least studied regions. Hadal zones, which begin at depths of around 6,000 meters, were once thought to be "biological deserts," but over time they have been shown to ...

Geological riddle solved: 'Roof of the World' has gotten higher

There has long been controversy about whether the world's highest region, Tibet, has grown taller during the recent geological past. New results from the University of Copenhagen indicate that the 'Roof of the World' appears ...

Imaging technique could identify where landslides are likely

Each year, landslides kill thousands of people around the world and cause catastrophic property damage. But scientists are still trying to better understand the circumstances that cause them. Doing so would go a long way ...
