New observations of mud cracks made by NASA’s Curiosity rover show that high-frequency, wet-dry cycling occurred in early Martian surface environments,...
Some steep slopes on Mars have gullies with morphologies suggesting that they were formed by a liquid. However, the planet’s current climate is not conducive...
Glacial cycles during the Early Pleistocene epoch are characterized by a dominant 41,000-year periodicity and amplitudes smaller than those of glacial...
Early humans and their hominin relatives had to adapt to new environments to spread out of Africa. In a new study, paleoanthropologists from the Institute...
In new research, scientists from the University of Cambridge and elsewhere reconstructed changes in summer and winter rainfall from trace elements and...
