Want to know what time it is? These days, it's as easy as looking at your phone. But before the digital age, Bay Area residents could dial POP-CORN or 767-2676 to hear a woman's recorded voice giving the time. Bay Curious unpacks the human history of this now obsolete telephone service.

In this week’s episode we revisit a question we first answered in 2018. What was Chicago’s response to the Civil War? Chicagoans support for the war was actually quite varied and changed as the war progressed. To answer the question we focus on the experience of Irish Americans and African-Americans and look at how the war went from popular to controversial in Chicago in just a few years.

Electricity from the sun is cheap and clean but the solar cells we see on our rooftops could be much more efficient. Henry Snaith of Oxford PV has developed a new material which helps solar roof panels extract more energy from the solar spectrum. Tom Heap visits Henry's lab and joins Dr Tamsin Edwards to consider the carbon-cutting potential of a new generation of solar energy.

Trees are often thought to be the good guys when it comes to climate change. In Siberia, however, it's not always the case. The landscape was changed when humans arrived and the forest that took over from grasslands is causing problems. In Pleistocene Park, Russian scientists are carrying out a radical rewilding - removing trees and reintroducing species of grazing animals to help protect the permafrost - the deep frozen ground - from thawing and releasing methane into the atmosphere. Tom Heap and Dr Tamsin Edwards consider how this ambitious idea could help in the fight against climate change.
