A mathematical model of a particle that remembers its past so that it never travels the same path twice produces stunningly complex patterns

In the foundations of a Maya temple, researchers found the charred bones of royal individuals – possibly evidence of a fiery ritual to mark the end of one dynasty and the beginning of another

Cloud seeding almost certainly did not play a significant role in the flooding on the Arabian peninsula this week – but the heavy rains may have been exacerbated by climate change
