How is technology being used to track Black Lives Matter protestors?
We've probably all heard the phrase 'Big Brother is watching you' (a reference to the fictional character in George Orwell's dystopian novel '1984') - but are we really under constant surveillance? Is it actually possible to be a fully functioning member of modern society without being tracked by some sort of surveillance system? And how is...
I was born in Shanghai, China. The majority of my school education took place during the infamous Cultural Revolution. There was no encouragement of academic achievement. Fortunately, the Cultural Revolution ended in 1976, when I was 16, and it became normal again for teenagers to study and apply for university places.

Seabird monitoring - witnesses in the wild
Seabirds – including penguins – are amongst the most threatened animals on the planet. They are also very useful indicators of wider environmental change. But how do you effectively monitor species which live in hard-to-reach places, such as Antarctica? A team of scientists at the University of Oxford has come up with a...

Learning and Efficiency of Outcomes in Games
Selfish behaviour can often lead to suboptimal outcome for all participants, a phenomenon illustrated by many classical examples in game theory. Over the last decade we developed good understanding on how to quantify the impact of strategic user behaviour on the overall performance in many games (including traffi c routing as well as online...
Positioning in challenging environments
From driving, to crop harvesting and timing in the financial markets, many aspects of our modern lives are reliant on GPS.
But, although they are everywhere, high frequency radio waves have a flaw. They are blocked by solid objects – like buildings – so they can’t reach everywhere.
