Earlier this year Crowdscience explored the question of time. Back then we were on a mission to uncover what the real time is and how we're able to measure time to ever greater degrees of accuracy. But as ever, the programme uncovered more questions than answers so presenter Anand Jagatia is back to try and find out where time comes from, why it runs forwards and not backwards, what happens to time in a black hole and does time even exist beyond our experience of it? We speak to Claudia Hammond, author of a book that reveals the mysteries of time perception and the man who defined time for the online Encyclopaedia Britannica, tells us if time really exists or not.

Under normal circumstances, if something was hurting you, you’d likely stop doing it. Except, well, as Theresa Marteau of Cambridge University’s Department of Public Health and Primary Care has explored deeply, in some key areas, you’re likely not stopping.
In a conversation with Social Science Bites host David Edmonds, she notes that the majority of premature deaths are due to four non-communicable diseases – diabetes, cancer, cardio-vascular disease, and lung disease. In turn, there are four main causes of these diseases – smoking, overconsumption of food, alcohol, and not moving around enough. All those causes, you’ll notice, flow from behavior.
And simply tapping someone on the shoulder and pointing out the connection has not been a particularly effective way to interrupt these pernicious behaviors.
“It’s quite a common idea that if people only understood better how they might be damaging their health, then they would tackle it,” Marteau explains. “Governments and others invest an amount of money in trying to communicate the risks to you and your health of engaging in these behaviors ... and while it can raise awareness, it’s not that effective at changing your behavior.”
That’s perplexing, Marteau admits, but undeterred she’s spent much of her career at the intersection of basic psychology, neuroscience and behavioral science looking for ways that do work to change behavior. And, as this podcast explores, she’s focused on the environment.
Or rather, environments.
As director of Studies for Psychological and Behavioural Sciences at Cambridge’s Christ’s College, her research group examines how environment – and that includes the cultural, built and financial environments --buttresses short term pleasures over long term benefits.
Taking a cue from Daniel Kahneman’s Thinking Fast and Slow, Marteau finds that the ‘bad’ behaviors in question ultimately—despite any initial enthusiasm at some point to quit smoking or go to the gym – default to the so-called ‘fast‘ brain system that oversees routine behaviors. These routines in turn are shaped, or perhaps amplified, by those environments.
Ultimately, Marteau focuses on addressing these harmful behaviors, work which this June saw her named Dame Commander of the Order of the British Empire for her services to public health. That work has her collecting evidence for redesigning environments to promote healthy behavior, which touches on public and private industry issues like product pricing, availability (and proximity), portion size, excise taxes, and many others -- “conceptually simple but legally and culturally more complex,” she admits.
We're always up for a challenge on CrowdScience but this week’s question, which comes from an artist, tests our limits as we investigate the nature of thought itself – something that has puzzled scientists and philosophers since ancient times.
Undeterred, presenter Nastaran Tavakoli-Far heads off to the Spanish island of Ibiza to visit listener Romanie in her painting studio and attempt to peer into the workings of her mind. As we explore the relationship between thought and language, why not join in with our experiments to discover if you’re thinking visually or verbally?
We find out how language can affect thinking in surprising ways – why German speakers might see a bridge differently from Spanish speakers, how being bilingual can make you a better driver and even why some languages give their speakers a remarkable sense of direction.

David in Bogota might have raised a few eyebrows in the CrowdScience office with his questions – can plants talk? And can they hear us talking to them? But actually scientists now know that plants do have the ability to communicate with the world around them to a much greater extent than previously thought. Some scientists even talk about plants being able to “hear” a hungry caterpillar or the sound of running water, while others argue that we should not anthropomorphise plants.
One underground communication network, affectionately dubbed the Wood Wide Web by scientists, is made of fungi that grow off the roots of plants. The network lets plants forge alliances, friendships and business partners.
But as we learn nothing is free in nature. In return for their haulage services, the fungi which make up the network siphons off some of the sugar produced during photosynthesis by the plants. Presenter Anand Jagatia goes foraging for answers in the woods together with fungal ecologists.

Back when Charles Darwin presented his theory of evolution by natural selection, French biologist Jean-Baptiste Lamarck suggested something different - that the changes you are exposed to during your lifetime can be passed on to future generations. By this theory, giraffes have long necks because, over generations, they have stretched them, reaching for leaves.
This theory became laughable when genes were discovered as the means of heredity. Lifestyle choices cannot be passed down in your DNA, or so we thought….But recently this idea has returned and a new field of biology has emerged called epigenetics – which looks at how the genes we inherit from our parents are controlled and modified by their life experience and the choices they made.
Marnie Chesterton meets the survivors of the Dutch Famine of World War Two, whose grandchildren show health effects from that event despite being born three generations after the starvation of 1944.
As the new field of epigenetics develops, does this mean Lamarck was right all along? Can your lifestyle be passed on to future generations and does this mean we need to rethink our traditional view of evolution?

Listener Ros Allen wondered why it always seems to rain on her village but not the one a mile away. It’s all down to microclimates. CrowdScience explores the impact of microclimates on our lives, discovers how more rain can help an English tea plantation and reveals the deadly effect of the urban heat island. Marnie Chesterton also talks to a local project in New York City, the Cool Roofs Program, that aims to reduce the urban heat effect, helping to mitigate the impacts of climate change. But just how much of a difference can measures like this really make?

Trees transcend human generations – but are they the oldest living things on Earth? CrowdScience listener William from London, UK, got in touch to ask what the oldest tree or other organism on our planet is. Presenter Marnie Chesterton heads out to meet one of our older arboreal cousins to see how we can work out its age - without cutting it down to count the rings. But whilst certain individual trees can live for thousands of years, some that live in colonies can survive for much longer – perhaps up to 80,000 years old. Along the way, Marnie asks what other organisms contend for this title, what the word ‘oldest’ really means, and even ponders whether some creatures could actually be immortal.

“Borders,” says Mary Bosworth, “are the key issue of our time.” And so, says the criminologist, “in response to the mass migration that’s happening, the criminal justice system is shifting. This shouldn’t surprise us – all other aspects of our society are changing.”
One of those changes is the creation of a new subfield of criminology, one explicitly evolved to understand immigration control and criminal justice. In this Social Science Bites podcast interview with Dave Edmonds, Bosworth talks about a field which she calls ‘border criminology.’
She starts the conversation by explaining that even the name of the field is a bit unsettled. Bosworth notes a couple of other terms making the rounds, including ‘crimmigration’ – coined by Juliet Stumpf -- and ‘criminology of mobility.’ The latter, she adds, doesn’t capture way that it’s the movement of people that’s being criminalized, and so “that doesn’t work quite so well in English.
“Border criminology as a term, I think, captures more clearly the way in which this is a field of study which is trying to understand both things that are happening at the border but also things that are happening n our criminal justice system.”
One of the main takeaways from her research has been that these detention centers are “very painful places for all the people concerned” – whether detainees and the officers. The officers themselves often “don’t fully understand what they’re doing” and “don’t have a clear narrative” of the population they are detaining, which runs from criminals to visa overstayers to people who just don’t have any papers.
As an academic who once did research in prisons, Bosworth finds “the detention estate is much more recent and politicized -- and doesn’t have tradition of letting researchers in.”
As someone who has been allowed in, Bosworth says she’s found policymakers are interested in hearing her results, but less so on acting on them. A “counternarraitive” on the threat posed by immigrants has created headwinds, she finds, that make reforming policy difficult despite the documented fiscal and human costs of the present system.
In this interview, she also describes the emotional toll on this sort of filed work, and some of the brighter spots of her efforts, such as creating an archive of artwork made by detainees.
Bosworth is a professor and fellow of St. Cross College at the University of Oxford and concurrently a professor at Australia’s Monash University. She’s the director of the interdisciplinary research group Border Criminologies and assistant director of the Center for Criminology at Oxford. She’s currently heads both a five-year project on “Subjectivity, Identity and Penal Power: Incarceration in a Global Age” funded by the European Research Council as well as a Leverhulme International Network on external border control.
You don’t have to be a “super-recogniser” to know that human facial features are extremely varied. Just look around you. Yet look at a most other animals and you’d find it hard to tell individuals apart. So why are human faces so diverse?
We’ll also be finding out why salt tastes salty (warning: lots of spitting and gargling ahead) and one listener wants to know what would happen if one of the key ocean current systems, the North Atlantic Conveyer, slowed down or stopped altogether. Presenter Marnie Chesterton heads to the beaches on the West Coast of Scotland in search of answer.

Childbirth is different for everyone. Depending on who you ask, it’s one of life’s greatest and worst experiences - and can be anything from traumatic and excruciating to life-affirming and spiritual. But what pretty much every mother will agree on is that it hurts. But why is such a fundamental aspect of life so painful? And why do some women find it worse than others?
Presenter Gareth Barlow – who doesn’t expect to be giving birth ever – goes on a quest to understand the experience of female labour pain and why evolution hasn’t given women an easier ride. He discovers the latest research into the nature and experience of pain and whether the idea of male/female pain thresholds, is a real thing. We also hear from CrowdScience listeners about their own experiences, and find out if having a supportive birth partner can help bringing new life into the world that little bit easier.
