13 July 2021 at 02:58

In spite of everything, many people still underestimate women, in general, and older women, in particular. They have clearly never encountered Kay Davies, the dynamic 70-year-old Oxford geneticist, who is β€˜retiring’ after a lifetime’s research (but not really).

Oxford researchers develop tool to predict human displacement post-disaster

12 July 2021 at 03:22

When disasters such as earthquakes happen, governments and humanitarian organisations need to rapidly allocate aid resources to facilitate recovery, minimise the number of people displaced and reduce the long-term effects. This is a complex task that needs be undertaken in a very short space of time, with potentially serious consequences if not done well.

Global Jet Watch: discovery of jets in classical novae

9 June 2021 at 06:11

Scientists at the University of Oxford have discovered that classical nova explosions are accompanied by the ejection of jets of oppositely-directed hot gas and plasma, and that this persists for years following the nova eruption.Β  Previously, such jets had only been encountered emanating from very different systems such as black holes or newly collapsing stars.
