The Tonga Eruption Left Deep-Sea Life Buried in Ash
When Hunga erupted in 2022, ash “decimated” slow-moving species living on the seafloor. More mobile species were able to hoof it out of harm’s way.

Toxic Metal on the Rise in the Baltic Sea
Postwar reconstruction is likely the cause of elevated thallium levels, but low-oxygen, high-sulfide conditions keep the material, which is extremely dangerous to mammalian health, from moving into the human food chain.

A Splashy Meteorite Was Forged in Multiple Collisions
The Winchcombe meteorite was recovered, largely from a driveway, just hours after it fell to Earth, preserving evidence that its early relatives could have filled Earth’s oceans.
