World Book Club - Lee Child – Killing Floor

World Book Club talks to one of the world’s leading thriller writers, British-born Lee Child. Killing Floor is the first book in the internationally popular Jack Reacher series and presents the all-action hero for the first time, as the tough ex-military cop of no fixed abode: a righter of wrongs, and not a man to mess with.

Early one morning Reacher jumps off a bus in the middle of nowhere and walks 14 miles down an empty country road. The minute he reaches the town of Margrave he is thrown into jail. As the only stranger in town a local murder is blamed on him, but as nasty secrets leak out, and the body count mounts, one thing is for sure: They picked the wrong guy to take the fall.

CrowdScience - How Bird-Like Were Dinosaurs?

Birds are dinosaurs, but did their extinct relatives move, look, or even sing like their avian relatives? From revealing the hidden information within fossilised dinosaur footprints, to reading the messages left by muscle attachments on fossil bones and seeing how modern palaeo-artists have started to draw fluffy feathered Tyranosaurs, presenter Geoff Marsh starts to reimagine dinosaurs as living animals.

Beginning with CrowdScience listener Malcolm asking about hopping dinosaurs while on a fossil finding mission with world expert Dr Peter Falkingham, Geoff explores the vaults of the Natural History Museum with Dr Susie Maidment and meets palaeoartist Dr Mark Witton’s pet dinosaurs in his living room studio.

CrowdScience - What is the future of space travel?

CrowdScience goes interstellar this week to answer listeners’ questions about the future of space travel.

Marnie Chesterton heads to Nasa’s Kennedy Space Centre in Florida, where she hears about the engineering challenges of creating a spacecraft that could eventually take us all the way to Mars. Then there are the challenges of engineering the humans for that momentous journey. In space, no-one can hear you scream, which is probably a good thing if you’re going to be trapped in a metal box for two years with the same people, as you cruise through the void on your way to the red planet. So how do astronauts prepare for the physical and psychological impacts of long-term space travel? We also discover how space travel can be made greener and cleaner as the European Space Agency implement the next phase of their plan to tackle the millions of pieces of space debris floating around our planet that potentially, could impact a mission before it even leaves Earth orbit.

CrowdScience - How Much Energy Can I Burn by Thinking?

Wouldn’t it be great if you could lose weight and stay fit just by exercising your brain? Trouble is everything takes so much effort - from burning off excess weight to powering our cars. But why?

Presenter Marnie Chesterton rummages through the CrowdScience inbox to tackle all your energy-expending queries. Is the entire universe spinning? How much energy do we expend when sleeping? Can I think myself thinner? Scientists Helen Czerski, Andrew Pontzen and Andrea Sella join listeners from around the world to discover how effort and energy affect our lives.

CrowdScience - Is There a Logic to Romantic Love?

Loving someone who doesn’t love you in return makes us feel wretched – can science explain why we must suffer? Parental love makes perfect evolutionary sense but romance just seems to have it in for us time after time. CrowdScience listener Leja wants to know why we fall in and out of love.

Marnie Chesterton discovers the irrational things, the impulsive things and the financially ruinous things BBC World Service listeners have done in the name of love and meet the rapper who turned herself into a science subject in an effort to flush out thoughts of her ex-boyfriend.

We delve into our ancestral past and into our brains to find out why romantic love is so central to the human experience.

CrowdScience - Why do Women Live Longer than Men?

From Russia to Rwanda, women live longer than men and have done so for over 100 years. But why? Is it encoded in our genes or is it something to do with the way we live? This is something CrowdScience listener Michelle from England has been wondering about. From cradle to grave, Marnie Chesterton examines the complex web of factors that are involved in how men and women age differently. It seems that, right from the word go, male embryos are already in the firing line because of their genetics. Marnie hears how women’s genetics are configured so that they have a backup copy of some of their genes, whereas men only have one copy. Not only does this make male embryos less resilient (and therefore more likely to miscarry), men are also at risk of a set of genetic diseases later in life like haemophilia. Puberty is an important component in this story too when a surge of hormones changes girls' and boys’ bodies into adults. But something in the way a boy develops sets them up for diseases late in life. They may be fitter, faster and stronger - all traits that were evolutionary important to make a man the alpha of the group - but this comes at a cost. For instance, the way that a man’s cardiovascular system is ‘configured’ means that they’re far more likely to have a heart attack than women. But it’s not just this, behaviour is also a really important factor and it’s why the gender gap in mortality differs from country to country. In Russia, the gap is nearly 13 years (the highest in the world) and it’s thought that a culture of heavy drinking and smoking is why women outlive men by more than a decade.

...which got Marnie thinking - could men change their destiny and outlive women? Presenter: Marnie Chesterton Producer: Graihagh Jackson

World Book Club - Chan Koonchung – The Fat Years

This month's World Book Club once again comes from China's capital Beijing. Lawrence Pollard interviews acclaimed and controversial writer Chan Koonchung about his much debated dystopian novel The Fat Years from a buzzy local bookstore in the city centre, filled with an audience of excited readers ready with their questions for the author.

Chan’s speculative fiction, The Fat Years, has been described as giddily daring. It imagines a time in the near future where China is the world’s dominant power and all Chinese are beamingly happy, all but our heroes who come to realise that a month has gone missing from history. No-one remembers it, no-one cares, so they set out to find it. The Fat Years has never been officially published in mainland China but has quite a reputation. Listen in and find out why.

CrowdScience - Is Soil The Secret to Slowing Climate Change?

Removing carbon dioxide from our atmosphere - and stopping it getting up there in the first place - is becoming increasingly urgent if we want to prevent catastrophic climate change. There are some seriously high tech machines being developed to try and tackle this problem, but could an equally powerful solution be found in the dirt under our feet? Prompted by New Zealand farmer and CrowdScience listener Kem, we dig deep to see how effectively plants and soils soak up CO2 from the air; and what that means for how we should farm the land around the world. And we visit a Scottish forest to find out how the ancient art of making charcoal is staging a comeback in the fight against climate change.
