There are a lot of myths about crystals − for example, that they are magical rocks with healing powers. An earth scientist explains some of their amazing true science.
Mineralogical analysis of 5,000-year-old stone beads from Turkana, Kenya suggest a novel mortuary tradition by early pastoralists.
A distant lump of space rock may have a surprising amount in common with the core of our own planet.
Mercury has shrunk by7 km. Most of this happened long ago, but now we have evidence that it continues.
Like icy thermometers, glaciers overlying volcanoes shift according to temperature changes below.
India’s Chandrayaan-3 rover has found sulfur on the Moon’s surface at higher concentrations than previously seen. Sulfur, a useful resource, could pave the way for future Moon bases.
More than 90% of the world’s pink diamonds came from a single mine that closed in 2020. Geologists are only now beginning to understand the forces that create the rare, highly prized gems.
A deadly earthquake in Afghanistan, following one in Morocco, highlights the risks in the region.
Many ‘myths’ are authentic memories of human pasts, told by people who passed down precise accounts of their history.
Ancient stories of the sea and the sky date back to the end of the last ice age.
Research on the Deniliquin structure points to an asteroid impact that would have been more than double the scale of the one that killed the dinosaurs.
Climate change is causing increasingly severe weather – but it’s not just hazards at the Earth’s surface we should be concerned about.
We’re having a big impact on the planet. But what marks will we leave behind in deep time?
New research dating and reading the rocks of the Flinders Ranges in South Australia reveals a fascinating story about how complex life emerged on our planet.
Scientists were not previously certain how the precious stones arrived at the Earth’s surface.
Our activities now affect the entire planet. But there’s a vital debate over when we started disrupting these systems. Was it 1950 – or hundreds and thousands of years earlier?
For some people, it’s a choice based on cultural beliefs or economic opportunities provided by the volcano. Other times it’s less a choice than the only option.
Variations in the thickness of tectonic plates may explain why Britain experiences many more earthquakes than neighbouring Ireland.
One in ten people around the world live near an active volcano. Understanding the drivers of eruptions is crucial.
