How are humans affecting bird populations in the UK?

Over the past 60 years since bird feeders first became commercially available, humans have been changing bird populations across the UK. The overall effect has generally been positive, with an increase in the prevalence of Wood Pigeons, and a shift in the migration pattern of Eurasian Blackcaps, but as with most changes, there is a word of warning… Live interview with BBC Radio Oxford.

How long is a lightning bolt?

A new record flash stretching all the way from Texas to Kansas was discovered recently in data from the GOES-16 spacecraft, though the record may soon be broken… Live interview with BBC Radio Oxford.

Caterpillars see using their skin

Possibly my favourite science story of 2019 – scientists at the University of Liverpool conduct 3 experiments to show that caterpillars of the peppered moth see using their skin. Live interview with BBC Radio Oxford.

How do Bubbles Freeze?

Freezing bubbles are not only beautiful, but also demonstrate incredibly complex physics. Here, Professor Jonathan Boreyko explains how bubbles freeze with examples of slow motion videos filmed in his laboratory at Virginia Tech.

This video is part of a collaboration between FYFD and the Journal of Fluid Mechanics featuring a series of interviews with researchers from the APS DFD 2017 conference.

Sponsored by FYFD, the Journal of Fluid Mechanics, and the UK Fluids Network. Produced by Tom Crawford and Nicole Sharp with assistance from A.J. Fillo.

Using maths to clean-up our oceans

Video of my ‘Teddy Talk’ at the 2019 St Edmund Hall open day.

Rivers are the major source of pollution in the oceans and if we are to clean them up, we first need to know where the majority of the pollution is concentrated. By creating a mathematical model for river outflows – verified by laboratory experiments and fieldwork – the goal is to be able to predict which areas are most susceptible to pollution from rivers and thus coordinate clean-up operations as effectively as possible.
