Rank #1: Global climate inaction
Fish could provide micronutrients to the world poor, but as we’ll hear this would need a major shift in commercial fishing practices globally.
Baby bottles from thousands of years ago suggest Neolithic people gave animal milk to their children.
And when did the Sahara develop? New findings in deposits from volcanic islands provides some evidence.
The number of vegans is on the rise in many parts of the world, with many people swearing by the health benefits of a plant-based lifestyle. But is a vegan diet really better for your health? Is there any evidence to show that vegans are likely to live longer?
And what about the new, highly processed meat analogues becoming increasingly available in supermarkets and restaurants menus? They look, feel and taste just like meat products but what affect are they having on our health? To find out more, we talk to the experts and join listener Samantha in following a vegan diet.

Rank #2: The birth of a new volcano
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?

Rank #3: New evidence of nuclear reactor explosion
Sociable, lively, outgoing people are highly valued in certain cultures - think of the stereotype of the hyper-confident American. And there’s even evidence that extroverts all over the world tend to be happier. But are the positive qualities that quieter types can bring to society being ignored or under-appreciated? And couldn’t introverts be just as happy as extroverts, if only they lived in a more accepting culture? We probe the links between happiness, personality and culture, and find out what makes introverts happy.

Rank #4: Embryoids from stem cells
Astronomers have detected water vapour in the atmosphere of a planet called K2-18b orbiting within the habitable zone of a distant star. The lead scientist, Professor Giovanna Tinetti of University College London, talks about the discovery and what she hopes to explore when a satellite telescope called ARIEL is launched by ESA in around a decade.
The World Health Organization ranks migraines as the second most disabling neurological disorder in the world and in people under the age of 50, it is the single most disabling medical condition. With stats like that, it’s no wonder that so many listeners have got in touch wanting help with their headaches. Peter from Germany askes what happens in his brain when he’s got a migraine, whilst Nika from Germany has found that changing lifestyle has dramatically reduced hers but she’s not sure why. What’s the link between diet, exercise and migraines, Nika wonders? Meanwhile, Judy from USA wants to know if there’s a cure, as her son gets chronic migraines and she wants to know what the future looks like for him. We investigate some of the latest research in headache and migraine research to find some answers.

Rank #5: South East Asia choking - again
In the Arctic ice melt this summer has been particularly severe, however the picture in complicated by climatic conditions. A new mission to the region involving trapping a ship in ice over winter hopes to provide answers.
Nearly 500 million of year ago the earth’s sky was darkened by a massive asteroid explosion, blotting out the sun. New data on this event may provide an insight into contemporary climate change.
Sir Arthur Conan Doyle’s famous fictional detective is renowned for his feats of memory, his observational capacity, tireless energy and an almost supernatural ability to solve the most perplexing crimes from seemingly unconnected facts. But what does science have to say about the matter? We pit fact against fiction with a leading forensic expert, a sleep scientist, and we discover that most humans are able to train their brain to rival the memory capacity of Sherlock Holmes. And who wouldn’t want that?
