All of those processes that are leading to the formation of hills and valleys have an effect

on cultural material. You can have rainfall, mobilising soils, biological processes like earthworm action, and windblown processes like blown sand.

Answers blowing in the wind and running with the rainfall on crowd science later in the hour, asking what comes before archaeology.

Before that, science in action is looking rather viral with questions about the new cases of monkeypox,

long-term COVID and the implications of an experimental vaccine.

Though, we're also looking at the health of forests as the world warms.

For the last 50 years in this tropical moist forest, we see that across species and sites,
