What do Mars and Iceland have in common? These days, not so much. But more than 4.5 billion years ago, it's possible the Red Planet had a crust comparable to Iceland today. This discovery, hidden in the oldest martian fragments found on Earth, could provide information about our planet that was lost over billions of years of geological movement and could help explain why the Earth developed into a planet that sustains a broad diversity of life and Mars did not.

Using details from historical newspaper accounts and letters, seismologists have learned more about Haiti's 1860 Jour de Pâques (Easter Sunday) earthquake sequence, and how it might have impacted the country's most recent devastating earthquakes.

Researchers recently discovered rare deep-sea brine pools in the Gulf of Aqaba, a northern extension to the Red Sea. These salty underwater lakes hold secrets into the way oceans on Earth formed millions of years ago, and offer clues to life on other planets.

A groundbreaking new study comprehensively accounts for the hydrological impact of lithium mining. Since lithium is the key component of the lithium-ion batteries that are crucial for the transition away from fossil fuels and towards green energy, it is critical to fully understand how to responsibly obtain the precious element.

By analyzing noble gas isotope data, a scientist determined that the ancient plume mantle (the deep part) had a water concentration that was a factor of 4 to 250 times lower when compared with the water concentration of the upper mantle.

The amount of carbon stored by microscopic plankton will increase in the coming century, predict researchers.

Efforts to conserve the carbon stored in tropical forests would be enhanced by linking the work to the charismatic, threatened primates that live there, researchers say in a new paper.

New research examines the potential for underwater noise pollution from seabed mining operations, which could affect the understudied species that live in the deep sea -- the largest habitat on Earth.

Lithium extraction from the deep sea, overfishing of deeper-water species, and the unexpected ocean impacts of wildfires on land are among fifteen issues experts warn we ought to be addressing now.

Researchers have established that the destruction of ozone over the Arctic in the spring causes abnormal weather throughout the northern hemisphere, with many places being warmer and drier than average -- or too wet.
