Tidal tomography reveals a thermal anomaly beneath Mars’s crustal dichotomy

Nature, Published online: 26 August 2026; doi:10.1038/s41586-026-10893-x Analysis of tracking data from Mars orbiters reveals time-variable gravity field behaviour reflecting the structure underlying the Martian crustal dichotomy and indicates the preservation of a 200–400 °C thermal anomaly in the present-day mantle below the southern highlands.

Strong oyster reefs start with genetic diversity

The European flat oyster (Ostrea edulis) was once widespread but has now become so scarce in the North Sea that it no longer forms ecologically functioning reefs. Along with the demise of the flat oyster, the three-dimensional structures that provide habitat for more than 100 marine species have disappeared.
