Human migration out of Africa may have followed monsoons in the Middle East
A new study by geoscientists and climatologists provides evidence that summer monsoons from Asia and Africa may have reached into the Middle East for periods of time going back at least 125,000 years, providing suitable corridors for human migration.

Secret of explosive volcanism unlocked
When will the next eruption take place? Examination of samples from Indonesia's Mount Merapi show that the explosivity of stratovolcanoes rises when mineral-rich gases seal the pores and microcracks in the uppermost layers of stone. These findings result in new possibilities for the prediction of an eruption.

Megadrought likely triggered the fall of the Assyrian Empire
The Neo-Assyrian Empire, centered in northern Iraq and extending from Iran to Egypt -- the largest empire of its time -- collapsed after more than two centuries of dominance at the fall of its capital, Nineveh, in 612 B.C.E. Despite a plethora of cuneiform textual documentation and archaeological excavations and field surveys, archaeologists and historians have been unable to explain the abruptness and finality of the historic empire's collapse.

Can machine learning reveal geology humans can't see?
Identifying geological features in a densely vegetated, steep, and rough terrain can be almost impossible. Imagery like LiDAR can help researchers see through the tree cover, but subtle landforms can often be missed by the human eye.

Evidence for past high-level sea rise
Scientists, studying evidence preserved in speleothems in a coastal cave, illustrate that more than three million years ago -- a time in which the Earth was two to three degrees Celsius warmer than the pre-industrial era -- sea level was as much as 16 meters higher than the present day.
