A new undersea volcano has appeared off the coast of East Africa. The sea floor between Madagascar and Mozambique has become increasingly seismically active in the last year. As well as the appearance of this active volcano, local islands are now experiencing frequent earthquakes.
The causes of Indonesia’s Palu Bay tsunami last year are being examined thanks to social media. Videos taken as the tsunami hit have been analysed to determine wave heights and speeds and suggest possible causes.
Scientists at a massive underground physics research facility in Italy are to stand trial over safety risks. The facility uses poisonous chemicals. There are concerns these could leak into drinking water supplies in the event of an earthquake.
As scientists keep finding ever more fascinating facts about the invisible housemates that share our homes, we investigate what might be lurking in quiet household corners or under our beds.
We head out on a microbial safari with expert tour guide Dr Jamie Lorimer from the University of Oxford to find out what kind of creatures are living in our kitchens, bathrooms and gardens - from bacteria normally found in undersea vents popping up in a kettle, to microbes quietly producing tiny nuggets of gold. For so long this hidden world has been one that we’ve routinely exterminated - but should we be exploring it too?

As scientists keep finding ever more fascinating facts about the invisible housemates that share our homes, we dust off our episode on what might be lurking in quiet household corners or under our beds.
Marnie Chesterton reminds us how dust can contain all sorts of secrets about our habits and everyday lives, and Anand Jagatia bravely ventures into parts of our homes that are usually overlooked. He heads out on a microbial safari with expert tour guide Dr Jamie Lorimer from the University of Oxford to find out what kind of creatures are living in our kitchens, bathrooms and gardens - from bacteria normally found in undersea vents popping up in a kettle, to microbes quietly producing tiny nuggets of gold. For so long this hidden world has been one that we’ve routinely exterminated - but should we be exploring it too?

Where the conditions are right, life can arise. But what might the ‘right’ conditions be? Could the dark sector of our Universe be inhabited? That’s what Gautam from Delhi, India has been wondering. He points out that dark matter and dark energy make up around 95% of the Universe and the remaining segment is normal matter - the stuff we’re all made up of. Given that there’s so much of this dark material, could dark life have evolved? Marnie Chesterton investigates with Dr Matt Middleton, Dr Burçin Mutlu-Pakdil and Dr Renato Costa.
Together, they unpick what dark matter and dark energy are and test out some listener theories as to what these mysterious mediums might be. For instance, Yoseph from Ogden, USA questions whether black holes could account for the missing matter and it turns out, he might just be on to something…

Our bodies are made of cells, tens of trillions of cells. They all have particular roles and functions in the body, from digesting food, to producing hair, to hunting down pathogens. But all of this incredible complexity started as just a single cell.
Gila, from Israel, asked CrowdScience to find out how the development of incredible structures, and systems in the body are coordinated by the cells. Are cells communicating? How do cells know what they should be doing?
To find out, Geoff Marsh meets a Cambridge researcher uncovering the first cell division in our lives, and peers into a fertile chicken egg to see the developing embryo as it grows a limb. CrowdScience finds out why scientists like Dr Megan Davey use chickens to understand the development of human fingers and investigates how individual cells with the same DNA manage to choreograph a dance of cell replication, movement and communication to create our bodies in all of their complexity.
Many of us enjoy cooking – but when did we switch from eating our food raw, to heating it? Listener Logan enjoys his beef burgers rare, but wants to know why he still feels compelled to grill them? Presenter Anand Jagatia travels to a remote South African cave where our ancestors first used fire at least a million years ago, which one man says could help prove when our species started cooking.
And he talks to a scientist who shows how the composition of food changes when it’s cooked, to allow us more access to give us more access to calories - and hears how a completely raw food diet could have disastrous consequences for health.

Humanitarian aid organizations often find themselves torn by reasonable expectations – to address a pressing crisis and to show that what they are doing is actually helping. While these might not seem at odds, in practice, says Monika Krause, they often do.
Krause, an assistant professor of sociology at the London School of Economics, is the author of The Good Project: Humanitarian Relief NGOs and the Fragmentation of Reason, an award-winning book from 2014. In her research, she conducted in-depth interviews with “desk officers” across a range of transnational non-governmental organizations (NGO) that respond to emergencies around the world distributing aid to save lives. (“For me,” she tells interviewer David Edmonds in this Social Science Bites podcast, “headquarters themselves were the field.”)
While she found that NGOs were “relatively autonomous,” their donors put pressure on them “to demonstrate results, and that pressure to show evidence, measurable results, may incentivize NGOs to do projects that are relatively easy to do. It certainly encourages NGOs to do kinds of work, and kinds of projects, where the success is more easily measured rather than other ones.”
While they may resemble businesses in some respect – and some use that observation as a pejorative, Krause notes -- they don’t distribute aid by purchasing power, as a private sector organization would, but rather by need.
The mechanics of this has meant that NGOs have become more focused on being accountable to the beneficiaries “rather than focus on more abstract and large-scale indicators” such as gross domestic product or greater employment which may ultimately improve the beneficiaries’ ecosystem. It also means, in practice, that NGOs focus on meeting the metrics they set at the beginning of a project, which may not serve the entirety of an affected population in crisis. And so, “beneficiaries can become a means to an end rather than an end in themselves.”
That people outside an NGO feel comfortable critiquing them reflects the unique role that NGOs, as opposed to say private businesses, occupy. “[NGOs] seem to represent or speak for our highest ideals as individuals and as humankind,” Krause says, which in turn can foster a sort of cynicism when the ideals the larger community expects aren’t met.
This tension has always intrigued the researcher, who had earlier won an ESRC Future Research Leaders Award to explore how organizations with values-based missions make decisions on how to deploy resources and who to help. In studying NGOs for The Good Project, “I was interested in the middle space, figuring out exactly how they do their work, how they confront the dilemmas that they must be facing ... about what to respond to and what not to respond to.”
Krause came to the London School of Economics in 2016 from Goldsmiths College, and at LSE is co-director of LSE Human Rights, a center for academic research, teaching and critical scholarship on human rights. In addition to her work on the logic of humanitarian aid, she is interested in the history of the social sciences and in social theory. Krause was a Poiesis Fellow at the Institute for Public Knowledge at her alma mater of New York University and a member of the Junior Fellows’ network at the Centre for Interdisciplinary Research at the University of Bielefeld. She was a core fellow at the Helsinki Collegium for Advanced Studies 2016-17.
We are slowly running out of ammunition to fight antibiotic resistant bacteria. Listener Peter wants to know whether a therapy that he’d heard about in the 1980s could be revived to help us where antibiotics falls short.
CrowdScience travels to Georgia where “phages”, viruses that hunt and kill bacteria, have been used for nearly 100 years to treat illnesses ranging from a sore throat to cholera. Phages are fussy eaters – a specific phage will happily chew on one bug but ignore another. In Georgia, scientists have kept rare phages safe for decades and are constantly on the look-out for new ones.
CrowdScience presenter Marnie Chesterton speaks to the scientists and doctors who are pioneering phage-therapy as well as overseas patients who have travelled thousands of miles in hope of finding a cure.

We are all made of particles – but what are particles made of? It’s a question that’s been perplexing scientists for centuries - for so long, in fact, that listener Doug in Canada wants to know if there’s a limit to how much they can ever discover.
CrowdScience heads out to CERN, in Switzerland, to find out. Birthplace of the internet, home to the Large Hadron Collider, and the site of the Higgs Boson’s discovery – the fundamental particle that is thought to give all other particles their mass, and one of the most important scientific finds of the 21st Century. But that revelation wasn’t an end to the quest – in fact, it has raised many more questions for the physicists and engineers involved. Dr David Barney, CMS, and Dr Tara Nanut, LHCb, tell us why.
And now they have announced that they are considering building a new, larger particle collider to find answers. The Future Circular Collider would be a hundred kilometres long and sited partly under Lake Geneva, smashing together sub-atomic particles at unprecedented energies in the hope of revealing the fundamental building blocks of all matter in the Universe. But any outcomes are by no means certain, and it could cost up to €29 billion. Perhaps physicists need to think completely differently about how to unpick what makes our universe – we see how one research team at Rutherford Appleton Laboratory near Oxford is doing just that, as they’re developing a collider that is not kilometres but centimetres long. Dr Charlotte Palmer, University of Oxford, tells us how.
However these fundamental questions are tackled, critics say that the money could be better spent on other research areas such as combating climate change. But supporters argue that its discoveries could uncover new technologies that will benefit future generations in ways we can’t predict. Anand Jagatia meets the scientists responsible to making this next giant leap into the quantum unknown.

Humans seem programmed to appreciate beauty - whether that’s an attractive face, a glorious sunset, or a stirring piece of music. Of course, our individual tastes are all different, and culture plays a huge part too - but why are we so struck by whatever it is we find beautiful? What is that pleasurable sensation we get when we see or hear something we like? And has the ability to appreciate beauty given us any evolutionary advantages?
In a special edition of CrowdScience from the International Science Festival in Gothenburg, Sweden, we are joined by a panel of experts to explore how far science can explain the mystery of beauty. We look to biology, the brain, art and mathematics, to see how patterns, rhythms and symmetry contribute to our experience of beauty. And we ask whether machines can recognise or ‘appreciate’ beauty – and to what extent artificial intelligence is starting to confuse or influence what we think of as beautiful.
There are very good reasons to sleep: to regulate the body’s metabolism, blood pressure and other aspects of health. But do we actually need to dream? Is there an evolutionary reason for it?
Marnie Chesterton takes her dream diary to a dream lab to explore this very popular preoccupation of many CrowdScience listeners.
What would happen if we didn’t dream? What purpose do dreams serve? Can we really interpret them meaningfully, or are they merely random signals from the brain? The latest research says talking about them could be more important than we realise.
And what about controlling our dreams? Marnie finds herself a willing participant in a study on lucid dreaming – of which sleep scientists are only just starting to understand the psychological benefits.
