Drilling into the past
from Science In Action Hosted by BBC World Service
Molecular biologist Prof Jason Chin tells us about his research into accelerated evolution and how it could help create new substances to be used in medicine, chemistry and more. In South America, palaeogeneticist Dr Verena Schuenemann has been extracting genetic material from human remains to find out more about treponemal diseases, which include syphilis, yaws and bejel. And moving across the Atlantic to the Mediterranean, volcanologist Professor Timothy Druitt has discovered new evidence of a massive volcano that erupted beneath the sea near Santorini around 500,000 years ago. Staying in the Mediterranean, we speak to Professor Rachel Flecker, co-chief scientist on Expedition 401 of the International Ocean Discovery Program. She and her team are drilling down into the seabed to establish how the Gibraltar Strait has altered over time. As well as influencing the Mediterranean's salinity, this changing movement of water has impacted the entire planet's oceans and climate.
