Revealed – the single event that made complex life possible in our oceans

The catalyst that allowed the evolution of complex life in Earth's oceans has been identified by a University of Bristol researcher. Up to 800 million years ago, the Earth’s oceans were deprived of oxygen. It was only when microorganisms called phytoplankton, capable of performing photosynthesis, colonised the oceans – covering two thirds of our planet – that production of oxygen at a massive scale was made possible.

Understanding the hidden causes of delays in discharging frail older people from hospital

Delays in discharging older people living with frailty from hospital are caused by a complex range of factors, but a key factor is how medical and social information about patients becomes fragmented during their stay. This is the conclusion of a study in two large NHS hospitals led by National Institute for Health Research (NIHR) funded researchers at the Universities of Bristol and Birmingham, published today [8 June] in Ageing & Society.
