NAU researchers find possible caves on Mars - Northern Arizona University
Applying techniques used to scope out caves on Earth to probe the possibility of caves on Mars is paying off. NAU researchers Glen Cushing and Jut Wynne, working at the U.S. Geological Survey, propose that photos from the Mars Odyssey mission reveal football-field size holes that could be entrances to caves.

Early Earth and Mars - Astronomy Magazine article
A team of scientists has found that terrestrial planets such as the Earth and Mars may have remained molten in their early histories for tens of millions of years. The findings indicate that the two planets cooled slower than scientists thought and a mechanism to keep the planet interiors warm is required.
