The roads and byways of the British Isles are home to a new generation of travellers. Alongside the traditional Gypsy, Roma and Traveller communities there’s a booming sub-culture of van dwellers who prefer the open road to bricks and mortar. For some it's a lifestyle choice. They spend the summer moving from festival to festival, picking up casual jobs as they go.

They celebrate their light touch on the planet and those who can afford it take the snowbird route for the winter, heading south through Spain. For increasing numbers, however, there's less glamour in 'van life'. Rapidly rising rents force them into vehicles and a long, cold winter searching for welcoming roadside stops with toilets and taps.

Travel writer and broadcaster, Antonia Bolingbroke-Kent has spent many months living out of her own battered VW van. She understands the fantasy and the practical difficulties. In the New Nomads she hears about both sides of van life and discovers new challenges on the horizon. For many travellers- traditional and new- the Police, Crime, Sentencing and Courts Act of 2022 feels specifically designed to make their lives as difficult as possible.

It creates a new offence of “residing on land without consent in or with a vehicle” and makes it easier for the police to remove unauthorised encampments. Fresh ideas are helping the increasing number of van dwellers.

In Bristol, brownfield areas are being turned into temporary spaces for vans and caravans. The residents are happy with these cheap and cheerful campsites but demand far outstrips supply. Unless more affordable homes are built it seems inevitable that more and more young people will have little choice but the open road.

Are we running out of water? Britain may be known for its rain but, as our climate changes, there are warnings we could be closer than we think to our taps running dry.

In this episode of Troubled Water, James Gallagher asks why our pipes are being pushed to the brink and what can be done about it, all from the comfort of his bathroom. Huddled in the loo, he talks to Professor Hannah Cloke, OBE, who predicts rainfall events through her work at the University of Reading, Dr Francis Hassard, from the Water Science Institute at Cranfield University, Andrew Tucker who manages water demand at Thames Water and inventor Garry Moore who shows how he's hoping to revolutionise our loos with his air-pressurised Velocity toilet.

Much of an astronaut’s leisure time is spent staring back at Earth, they just can’t stop looking back at home. Major Tim Peake journeys into the misunderstood phenomenon of homesickness.

Tim had never experienced it until he found himself looking through the copula window of the space craft, which orbited earth several times before reaching the International Space Station. The British astronaut spent 185 days, 22 hours and 11 minutes in space and during that time, developed a deep longing for home, particularly fresh air, nature and the colour green.

But what is this powerful desire for home? Is homesickness a psychological illness? A cultural phenomenon? Or something else? Psychotherapist Sarah Temple-Smith who works for the Refugee Council believes the condition is widely misunderstood and its impact critically under-appreciated. She believes it’s a deep-rooted condition with existential consequences.

Speaking to those who suffer from it, and those who study it Tim attempts to understand exactly what homesickness is: how it manifests, what it feels like, and the psychological triggers that underpin it.

Situated 75-miles off the west coast of Shetland, the future of Cambo, a prospective new oil field in the North Sea, has big implications for Shetland. Cambo has become emblematic of the debate about fossil fuels.

In 2001, an oil exploration license for the site was granted. In 2021, when public sentiment towards fossil fuels cooled, the project was shelved. But now, Cambo is being reconsidered once again... The war in Ukraine and fears over energy security have changed how we feel about oil and gas. But what's the problem that Cambo is providing a solution to? Will it give us better energy security? Will it enrich the lives of local people?

Turns out, the answer is more complex than that... Shetland has directly benefitted from its relationship with North Sea oil. Unlike in the rest of the UK, the local council established something akin to a sovereign wealth fund. They made a proceed from every barrel of oil processed at Sullum Voe Oil Terminal. It's really positively impacted the local population, and as the cost of living crisis bites, the chance of a renewed boost to the local economy is hard to entirely reject, even in the face of growing environmental awareness. In this one-off doc, journalist Jen Stout assesses how the potential end of oil looks from Shetland's perspective.

With contributions from historian Ewan Gibbs, energy researcher Miriam Brett, environmental lawyer Tessa Khan, energy transition expert Daniel Gear, former oil worker and councillor Billy Fox, and energy and climate change researcher James Price.

The word “controversy” almost always accompanies any reference to ECT or electroconvulsive therapy. It has a dark history and remains a deeply contentious practice.

For many, ECT is seen as outdated, forever linked with frightening images of medical abuse, cruelty and even punishment. But when Professor Sally Marlow met Dr Tania Gergel at King’s College London, she was forced to acknowledge and then reassess everything she thought she knew about ECT. Her friend Tania told Sally that ECT had saved her life on numerous occasions and that ECT is, in fact, the only treatment that can bring her back to health after episodes of severe depression, psychosis and mania.

Tania is Director of Research at Bipolar UK. She’s a philosopher and an internationally respected medical ethicist. She also lives with a serious mental illness; an unusual mixed type of bipolar disorder, and during her last period of illness a year ago, Tania kept an audio diary.

In this programme, Sally wants to test her own preconceptions about ECT and to find out about the group of people who describe ECT as having "given them back their lives". She delves into her own family history and talks to her mum, Kath, about the secrecy and shame around the mental illness of her Auntie Joyce, who received ECT in the 1960s. And she joins Tania in the ECT suite at Northwick Park Hospital with nurses Anjali and Kathy to understand how modern ECT is given, with anaesthetic, muscle relaxants and, as Tania says, much kindness.

Retired social worker, Sue, tells Sally about the dramatic impact on her acute illness of ECT and clinician and researcher Professor of Psychiatry George Kirov, ECT lead for the Cardiff area, describes the group of patients for whom this treatment works. And Sally talks to the grandfather of American ECT, Professor Max Fink, now 100 years old, about the origins of electroconvulsive therapy. Throughout, Tania shares extracts of her audio diary in order to break down stigma around both mental illness and ECT.

Matthew Syed traces the history of a term that's synonymous with our era of angry debate.

Historian Phil Tinline explores why, 37 years ago, the Thatcher government privatised British Gas, how what followed has shaped today's energy price crisis - and what should happen next.

It seems like an impossible conundrum. Ukraine is valiantly defending itself against the man Boris Johnson called "a blood-stained aggressor" and fighting for survival in a war that is currently deadlocked.

President Zelensky has warned that attempts at talks with The Russian Federation will fail, because Vladimir Putin cannot be trusted. So in the absence of a decisive victory or a negotiated settlement - what happens? James Naughtie investigates how other conflicts have come to a conclusion, in a bid to shed light on a war which has so far defied predictions.

He will talk to key figures who have been in the room as peace deals are ground out - and visit the law makers in Washington DC who are the key source of defence funding for Ukraine. History may have lessons when it comes to a conflict for which there seems no end in sight.
