Palaeontology Goes Hi-Tech

Palaeontology strives to discover evidence so that we might learn more about the fossil remains of life and understand how they lived, functioned and even died. Scientists at The University of Manchester have been using state-of-the art imaging, chemical analyses and computer modelling techniques to study the...

Neptune's Flowers

Seagrass meadows are an important environment in the Mediterranean and around Australia. They support diverse wildlife communities and act as carbon stores. This article explains what seagrass is, its value and the human threats to underwater seagrass meadows.
