A very dark day
b'
In the week of the solstice \\u2013 the shortest or longest day of the year depending on your latitude - Unexpected Elements brings you tales of darkness and light.
We hear about the dark history of sensory deprivation studies and why up until now, we\\u2019ve been in the dark about light\\u2019s role in the fairly fundamental process of evaporation.
We\\u2019ll be shining a light on the darkest oceans, meeting the fantastical creatures who can turn their bodies into flashlights.
Our Under the Radar story this week also comes from the sea as we discover how fish skin is helping to treat burn victims in Brazil.
We have an Ask the Unexpected question about why we don\\u2019t sneeze when we\\u2019re asleep, and more of your emails and voicenotes about obscure sports, tunnel living and earworms.
We even find time to wonder why the Brazil nut isn\\u2019t called the Bolivia nut.
Presenter: Marnie Chesterton, with Camilla Mota and Chhavi Sachdev
Producer: Ben Motley, with Dan Welsh
