Time waits for no one, but what exactly is it? Is it just a human construct, or something far deeper, flowing through our minds and bodies? In this episode, we examine the very fabric of time: how we created it, how we perceive it, the hidden rhythms of our body clocks, and what the future might hold as science and technology bend the boundaries of time...

Across our planet, natural archives preserve the biological footprints of species long gone, from woolly mammoths at the macro scale, through plants and seeds, to dormant bacteria and viruses at the micro end of the spectrum. And one environment that safeguards some of this material in the best condition of all is the cold - in other words, in ice. So, this week, we're going to look at what is sitting in nature's deep freeze... Like this podcast? Please help us by supporting the Naked Scientists
