Flowering plants outcompeted conifers

As evolutionary biologists, one of our major objectives is to understand how competition for resources regulates the appearance and extinction of species and can lead to the increase or decline of entire groups of species. This is particularly difficult to study because each group has... click to read more

Our Galaxy is shooting out bullets of cold gas

The central regions of disk galaxies are large-scale powerhouses. Galactic nuclei usually host super-massive black holes that release huge amounts of energy when matter spirals around them and eventually falls onto them. Many galaxies also show strong star formation activity in their inner regions, with... click to read more

Bee aware! Signs of a global decline in wild bee diversity

Everyone likes bees; they are fuzzy, love flowers and do many great things – but they might not be around for much longer. Although most of us are familiar with the European honeybee, this is but one of over 20 thousand species of wild bees, and... click to read more
