Rank #1: 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 #2: Nanotube computer says hello
Satellites have transformed our lives, giving us digital communications, navigation and observations of Earth, and even an artificial place to live above the atmosphere: The International Space Station. But, would more of these satellites and stations help us get back to the Moon, as well as further into the solar system? What else would astronauts need for living beyond Earth? We ask the engineers working on the possibilities – from communications satellites that could transform lunar missions to a brand new moon-orbiting space station: The Lunar Gateway.
These technologies could help humans get back to the Moon, and perhaps one day to Mars, for hopefully reduced costs – but funding missions beyond our planet still isn’t going to be cheap. Why might we need deep space-based infrastructure, and how could it help humanity back here on Earth?

Rank #3: Amazonian fires likely to worsen
Many of us struggle to motivate ourselves to carry out certain tasks, from hanging out the washing to writing a job application. How can we best motivate ourselves? And how can we avoid procrastination? Listener Moses in Uganda wants to find out. Anand Jagatia puts science to the test as he trains and participates in an open water swimming race which Marnie Chesterton has kindly volunteered him for.

Rank #4: Cracking the case of the Krakatoa volcano collapse
Wyoming Dinosaur trove
The BBC got a secret visit to a newly discovered fossil site somewhere in the US which scientists reckon could keep them busy for many years. Jon Amos got to have a tour and even found out a tasty technique to tell a fossil from a rock.
Researchers at Cornell University’s Carla Sagan Institute report their work thinking about detecting alien life on distant planets orbiting other stars. Around 75% of stars are of a type that emits far more dangerous UV than our own sun. What, they argue, would a type of life that could survive that look like to us? Well, just maybe it would act like some of our own terrestrial corals, who can protect their symbiotic algae from UV, and in doing so, emit visible light. Could such an emission be detectable, in sync with dangerous emergent UV flares around distant suns? The next generation of large telescopes maybe could…
Jinsoo Kim and David Perry of Harvard University tell reporter Giulia Barbareschi about their new design for a soft exosuit that helps users to walk and, crucially also to run. They suggest the metabolic savings the suit could offer have numerous future applications for work and play.
Listeners Mark and Jess have been watching TV series, The Handmaid’s Tale. It's an adaptation of a book by Margaret Atwood and depicts a dystopian future where many have become infertile. The remaining few fertile women, known as Handmaids, are forced into child-bearing servitude. Why so many have become infertile isn’t clear but the series hints at several possible causes, from radiation to environmental pollutants.
All of which got Mark and Jess wondering… What could cause mass infertility? Would we descend into a political landscape akin to Gilead? Award-winning author Margaret Atwood has left a paper trail for us to follow in the pages of her novel. There’s a ream of possible causes, and so Marnie Chesterton investigates which ring true.

Rank #5: 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?
