What is time?

This week, we are exploring the oil and gas industry, literally from the ground up: what's the geology of oil formation, how does a petrochemist go from crude to highly refined, can the UK solve its energy price problem by actually using the oil on its own doorstep, and what lies downstream of oil as we transition to alternatives?

This week, we find out how space travel is likely to affect the bodies of the Artemis II astronauts. Plus, how conflict and other adverse events during childhood influence young lives, what is the link between chronic pain, stress and the brain, and how male octopuses use a specialised arm to find mates...

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

This week: social media's role in user harm and the plausibility of app addiction, a sunken Soviet sub revealing how nuclear materials behave deep underwater, a hidden "magnetic shadow" on the Moon that could improve space travel safety, and the science behind the famous "waggle dance" performed by honeybees....

Coming up, we explore the race back to the Moon. Why are we going? How will we get there? Can we live and work on its surface? And what can we grow when we get there? We explore the science, the engineering, and the possibilities of humanity's next giant leap... Like this podcast? Please help us by supporting the Naked Scientists

Coming up, we explore an outbreak of meningitis in the English county of Kent. Will a targeted vaccination campaign bring it under control? Plus, a fast diagnostic swab test that may help diagnose schizophrenia, how thousands of old tumour samples could aid our understanding of rising bowel cancer rates in people under 50, and a new study that suggests ultrasound could help save European hedgehogs from road traffic...

For Endometriosis Awareness Month, we explore a condition which affects 10% of women around the world. Cells that form the lining of the uterus crop up in other parts of the pelvis, and elsewhere in the body. It prevents many patients from being able to carry out everyday tasks, and can also cause infertility. In this episode, we explore the condition, hear the experiences of those living with endometriosis, discuss the science behind it, and find out about the treatments of tomorrow... Like this podcast?

Coming up, we assess the environmental and health impact of conflict in the Middle East. Plus, the gene variants that affect how heavily someone smokes, a medication called ruxolitinib that could help the vitiligo community, and a fascinating new study on interbreeding between Neanderthals and humans...
