Forty years on from the Chernobyl disaster, we discuss radioactive fallout and our relationship with nuclear risk. In sport, researchers suggest repeated head impacts may disrupt the blood-brain barrier, potentially increasing dementia risk in retired athletes. And a new approach offers hope for speeding up recovery from ash dieback in affected woodlands... Like this podcast? Please help us by supporting the Naked Scientists

Today, we are taking a journey through the evolution of space telescopes and observatories. They are continuing to drive our understanding of the Universe, and the latest iterations - the Vera Rubin Observatory and the Nancy Grace Roman Space Telescope - are hoping to go even further. But what are these ambitious eyes on the sky revealing? Like this podcast? Please help us by supporting the Naked Scientists

This week scientists confirm the link between changes to the microbiome and later development of Parkinson's Disease, a super speedy microfluidic way to diagnose infection and probe antibiotic susceptibility, how many infections does daycare cause in your toddler, and the breakthrough capable of boosting laser power by orders of magnitude...

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
