Last weekend a chemical ‘haze’ on the East Sussex coast saw 150 people needing hospital treatment after something in the air led to streaming eyes, sore throats and nausea. Leading theories so far include a chemical spill from shipping in the English channel, a localised spike in ozone levels and an algal bloom, where algae suddenly proliferate and release harmful gasses. Dr Simon Boxall of the National Oceanography Centre at the University of Southampton tells Gareth Mitchell why he’s favouring the algal bloom theory.
We know about extinct species from fossils in rocks. But in the future there will be techno-fossils too, evidence of our civilisation. Katie Kropshofer has been finding out from Professors Jan Zalasiewicz and Sarah Gabbot of the University of Leicester what we’re leaving for the hypothetical geologists of the future.
Neuroscientist Joseph Jebelli's book, In Pursuit of Memory: The Fight Against Alzheimer's, is the one of the six titles on the shortlist of the Royal Society Insight Investment Science Book Prize. He explains to Gareth Mitchell that it was his grandfather's development of the condition that made him interested in Alzheimer’s.
The Big Wasp Survey is a citizen project to trap wasps and send them off to teams at the University of Gloucester and University College London, so that scientists can then learn more about the distribution of different species around this land. One of the organisers, entomologist and professor of Science Communication at the University of Gloucester Adam Hart, talks to Gareth about why these unpopular insects are ecologically valuable.
