This week we turn our gaze skywards to tackle three questions about what’s going on above us. Three year old Zac from the UK wants to know what clouds feel like – if they’re supposedly like steam, then how are they cold?
Presenter Graihagh Jackson meets a meteorologist who can not only tell us but show us the answer, as we attempt to make a tiny cloud at ground level in the studio. Listener Agnese is looking beyond the cloud base and up to our nearest neighbour. She’d like to know why it is that we can see the Moon during the day. And Graihagh heads out to one of the longest-running and largest steerable telescopes in the world: The 76-metre Lovell Telescope at Jodrell Bank Observatory in the UK. Here, she finds out the answer to Sandeep from India’s extra-terrestrial question: Could aliens find us?

Data about us as individuals is usually conceived of as something gathered about us, whether siphoned from our Facebook or requested by bureaucrats. But data collected and displayed by the tracking applications on our iPhones and Fitbits is material we collect by ourselves and for ourselves.
Well, maybe, says sociologist Gina Neff, who with Dawn Nafus (a senior research scientist at Intel Labs) wrote the recent book, Self-Tracking. In this Social Science Bites podcast, Neff tells interview David Edmonds that such information – your information -- is widely available to the device or software maker. Now combine that with social network data – and many apps essentially require you connect those dots – and what results is an unintentionally rich portrait of the user. And that digital you, your doppelgänger, gets shared widely, whether you want it to or even if it’s an accurate depiction, at times making the difference in decisions of whether you worthy of that job or ought to be insured.
Neff said she thinks of tracking devices as a sort of “bait and switch,” since their outputs aren’t wholly your own. As anthropologist Bill Maurer has said, data doesn’t have ownership so much as having parents.
But Neff doesn’t approach smart devices as a Luddite or even that much of an alarmist; she bought first-generation Fitbit when they were brand new and virtually unknown (all of five years ago!). She approaches them as a sociologist, “looking at the practices of people who use digital devices to monitor, map and measure different aspects of their life.”
Many people with and without activity trackers feel they already track their lives – through a tally they keep in their head. Think of the item of clothing – say those ‘skinny jeans’ - you wear when you feel you’re particularly slim. “One of the things that motivated us in thinking about the book were these qualitative measures that help people understand their lives and give them a sense of tracking that is more empowering in some ways.” And one of the findings is that a low-common-denominator approach to the devices can prevent people from really taking control, or customizing the collection, of their own data. “For too many people,” Neff says, “they can’t access and control their own data on the devices in order to begin to frame the next question.”
Her findings on smart devices surprised her several times. For example, she explains, many of today’s digital artifacts are anchored in much older sociological practices. She cites Lee Humprheys’ examinations of how Twitter use lines up with how diaries were used in the 19th century: “Lo and behold, some of those same short entries – ‘Had breakfast late,’ ‘It rained today’ – that we think of as disposable and part of the digital era really are much older.”
Neff was also taken aback at who the audience is for self-tracking. “I thought I was going to study just these kind of geeky, West Coast, Silicon Valley, male types who wanted to engineer everything about their life. And boy, was I wrong.” Users are much more diverse, and often less self-absorbed; some people are using the devices to stay on top of medical concerns, and other just want to be more productive in everyday life. And their devotion can be ephemeral – Neff said studies find 60 percent of activity trackers get disused within six months.
Neff is an associate professor, senior research fellow, program director of the DPhil in information, communication and the social sciences at the Oxford Internet Institute. Self-Tracking, which reviewer Simon Head at The New York Review of Books described as “easily the best book I’ve come across on the subject,” is her third book. Earlier volumes were 2012’s Venture Labor: Work and the Burden of Risk in Innovative Industries, which won the 2013 American Sociological Association Communication and Information Technologies Best Book Award, and 2015’s Surviving the New Economy (with John Amman and Tris Carpenter).
The size of brains in the animal kingdom is wildly different, from melon-sized in blue whales to pea-sized in shrews. But does a bigger brain mean a more powerful one?
CrowdScience listener Bob wondered just this as he watched various sized dogs running amok in his local park: the Great Dane has a much larger brain than a Chihuahua’s, yet the job of ‘being a dog’ surely requires the same brain power. So why have a big brain if a small one would do?
A search for the answer takes Geoff Marsh to dog agility trials, behind the scenes at London’s Natural History Museum and a laboratory that studies bumble bees. It turns out that size does matter, but not in the way you might think.

Our species started in Africa, but what was the last habitable landmass we reached? CrowdScience presenters Marnie Chesterton and Geoff Marsh team up to investigate how and when our species journeyed around the world and settled its most far flung landmasses. Geoff heads to some ancient caves in Israel to investigate the ‘false starts’ humans made out of Africa, and Marnie speaks with Professor Lisa Matisoo-Smith in New Zealand, uncovering the development of Polynesian sailing canoes and how they enabled the last landmasses to be found by people. This is a story spanning over seventy thousand years, huge changes in culture and technology, and the repeated remodelling of the earth thanks to the ice ages.

It’s the sort of plot you would expect from a classic sci-fi movie; what if there are viruses trapped deep in Antarctic ice that could wreak havoc on humans?
Crowdscience presenter Alex Lathbridge puts on warm gloves and meets the scientists venturing into the icy wilds. He wants to answer listener Tony’s question - can viral life exist in such inhospitable climes and if so, might it pose us a danger?
Alex meets teams who venture to the Antarctic to find out about how their work to understand climate change leads them to drilling and analysing ice cores that are tens of thousands of years old. He then visits a dynamic husband and wife duo in France who are extracting viruses from 30,000 year old Siberian permafrost and bringing them back to life. He discovers that - rather than killing us all, - their findings of novel giant viruses might contribute to medicine and our understanding of evolution.

Waste, trash, garbage – whatever you call it, unwanted materials have become a major presence in many of our lives and our environment. Every year it is estimated that humans around the world produce 2 billion metric tonnes of waste. Listener Clare from Devon in the UK wants to start tackling this herself. She would like to know if she can not just sort but process all her own recycling at home.
Presenter Marnie Chesterton attempts to find out by asking the professionals. She heads out to an industrial-scale recycling plant to see if any of their gear could work in our homes, hears from reporter Chhavi Sachdev how waste collectors in Mumbai, India have to balance thrift with risk, and asks environmental engineer Jenna Jambeck whether she thinks solely domestic recycling is possible.

Sociologists Les Back and Shamser Sinha spent a decade following 30 migrants in London, a study that forms the narrative in their new book, Migrant City. But the book, which includes the names of three of their subjects as additional co-authors, doesn’t focus the lives of 30 characters, but 31.
“In the end,” Back tells interviewer David Edmonds in this Social Science Bites podcast, “Shamser Sinha and I learned so much about not only the experience of migration, but about London as a space and a place that is made through migration. So this is not really just a migrants’ story; it’s the story of London but told through and eyes, ears and attentiveness of 30 adult migrants from all corners of the world.”
Given the focus on immigration at present – whether into the European Union from the developing world, into Britain from the rest of pre-Brexit Europe, or into the United states from points south – Edmonds inquires whether the immigrants were in London legally or not. They were both, although Back notes that migrants in general often pass between the two states. The question itself allows Back to expound on the way that that binary colors so much of the conversation about immigration.
“The idea of the immigrant itself holds our thinking hostage very often; that’s one of the big points we wanted to make. It’s so coded, it’s so symbolic in our political culture, particularly the legal/illegal ones that bear down on the public debates – the good migrants vs. the unwanted ones.”
Sinha and Back’s work was part of a larger European Union-funded seven-country study of migration in Europe. The pair’s longitudinal ethnography In, and of, London was accompanied by a conscious effort not just to “mine” the 30 migrants of their personal experiences and data; the sociologists were “doing research alongside people, instead of just in front of them and on them.”
Many of the migrants were happy to become more than mere subjects, hence the writing credit for three of them.
“To say that the participants are co-authors, on the one hand, is an attempt to honor their contribution,” Back recounts in explaining the unique two-plus-three byline. “On the other hand, we felt there was a bit of sleight of hand, because at the end of the day Shamser and I spent 10 years listening to people, thinking about the way they documented their own lives and observed their own lives and the way we made sense of that. At the end of the day, Shamser and I pulled this piece of writing together and shaped it. So it would be wrong to not acknowledge that.”
Back describes both the alienation the migrants experienced, but also their “enchantment” with being a London, a city which had often loomed large in their lives well before they set off to live there. “Very often, those young people were here because British interests, or London’s interests specifically, had been alive in the places where they grew up, their hometowns and their far-off places. ... They are here because we were there, or continue to be there.”
A native Londoner, Back is a professor of sociology at Goldsmiths, University of London. He is both a student of Goldsmiths, having done undergraduate and postgraduate studies there, and since 1993 has been on the faculty there.
In that time he’s written number of books, including 2007’s The Art of Listening; 2002’s Out of Whiteness: Color, Politics and Culture (with Vron Ware); and 2001’s The Changing Face of Football: racism, identity and multiculture in the English game (with Tim Crabbe and John Solomos). In 2016, his Academic Diary: Or Why Higher Education Still Matters, was the first book ever published by the then new Goldsmiths Press.
The ritual of burying the dead stretches back to the obscure beginnings of human history - and perhaps beyond, with archaeologists uncovering evidence of burials that pre-date our own species. But why do we bury our dead? How important is it, and how did the practice evolve? CrowdScience listener Moses from Uganda began pondering these questions after attending a close relative’s funeral.
We search for clues in some of the earliest known burial sites, compare other methods for dealing with human remains, and explore how the funeral practices around the world today compare to those of our ancestors. Did these rituals originally develop for reasons of simple hygiene, or are religious and symbolic aspects the real key to understanding them?

When CrowdScience listener, Grady, crashed violently on his motorbike in the desert, he thought he was going to die. Years later he still can’t remember the dramatic seconds just before the impact. Where did the memory disappear to? Did the hard hit to the head knock his memories out or are they still in his brain somewhere? CrowdScience turns to brain science to find out if those last few seconds are lost for good or if the brain tells a different story.
Under normal circumstances our brains like to hold onto memories that are emotionally important to us. We can remember our wedding day but not yesterday’s breakfast. But scientists have discovered that during near-death experiences, our brains are flooded with chemicals that disrupt our ability to remember. Grady may never recall how he was able to keep his motorbike steady as he drove off the road because – maybe – the memory was never created in the first place.

Magma is the hot, molten rock found beneath the Earth’s crust. It’s so plentiful that it got Greek listener Dimitrios wondering whether we could harness this heat. Could we drill directly into the magma and use it to power our homes, he asks presenter Marnie Chesterton? And from Ghana, Madock also got in touch with CrowdScience to ask why there are lots of volcanoes in some areas of the world, but then none in others?
Marnie dispatches Anand Jagatia to Kenya, a country that is one of the biggest providers of geothermal energy in the world and home to the East African Rift system. At 4,000 miles long, a string of volcanoes sits along this fault line. Anand hikes up one of these to find out why volcanism is so active here. Anand then travels to a geothermal power plant to get to grips with how conventional geothermal energy works, before turning to Iceland, where they’ve drilled directly into magma - albeit by accident. What they discovered was supercritical steam. It’s neither a liquid nor a gas but holds up to 10 times more energy than both. And to find it naturally occurring is the ‘holy grail’ of geothermal power. But can our equipment stand such temperatures?
