"I'm determined to prove botany is not the 'Cinderella of science'". That is what Professor Kathy Willis, director of Science at the Royal Botanic Garden in Kew, told the Independent in 2014. In the two years since she took on the job at Kew she has been faced with a reduction in government funding. So, Kathy Willis has been rethinking the science that is to be done by the staff of the Gardens and has been criticised for her decisions.

But as well as leading this transformation, Kathy has a distinguished academic career in biodiversity. She is currently a professor at Oxford University and, during her research career, she has studied plants and their environments all over the world, from the New Forest, when she was a student in Southampton, to the Galapagos Islands where she studied the impact of the removal of the giant tortoises on the vegetation there.

Patrick Vallance is something of a rare breed - a game-keeper turned poacher; an academic who has moved over into industry. And not just any industry, but the pharmaceutical industry. At the time, Patrick Vallance was professor of Clinical Pharmacology and head of the Department of Medicine at University College London. A pioneer of research into some of the body’s key regulatory systems, he had also been publicly critical of big Pharma for “funding studies more helpful to marketing than to advancing clinical care”. So what made him go over to "the other side"?

His involvement with the industry was limited until one evening in 2006 when he was asked a question over a dinner, a question that would be pivotal to his life and career.

Today, Patrick is head of research and development at GlaxoSmithKline, one of the world’s largest pharmaceutical companies with annual revenues in excess of £20 billion and nearly a 100,000 employees worldwide. Whilst GSK is no stranger to scandal, since he joined, Patrick has attempted to tackle the culture of secrecy that pervades the industry. He has since reshaped the way GSK carries out its research and has been behind several radical initiatives in global healthcare, to produce a more collaborative approach to tackling major diseases like malaria.

Professor Robert Plomin talks to Jim al-Khalili about what makes some people smarter than others and why he is fed up with the genetics of intelligence being ignored. Born and raised in Chicago, Robert sat countless intelligence tests at his inner city Catholic school. College was an attractive option mainly because it seemed to pay well. Now he is one of the most cited psychologists in the world. He specialized in behavioural genetics in the mid '70s when the focus in mainstream psychology was very much on our nurture rather than our nature, and genetics was virtually taboo. But he persisted conducting several large adoption studies and later twin studies. In 1995 he launched the biggest longitudinal twin study in the UK, the TED study of 10,000 pairs of twins which continues to this day. In this study and in his other work, he has shown consistently that genetic influences on intelligence are highly significant, much more so than what school you go to, your teachers or home environment. If only the genetic differences between children were fully acknowledged, he believes education could be transformed and parents might stop giving themselves such a hard time.

Can we make better surfing waves than the wild ocean, asks marine biologist and writer Helen Scales.

Helen loves surfing but she describes it as an extreme form of delayed gratification, especially around the British coast. Nature does not make great surfing waves to order. Waiting for the perfect wave demands patience, a warm wet suit and a cool head (especially if somebody jumps the queue and steals your ride). Becoming skilful on a surf board takes years if you can only practise on what the wild sea provides and even longer if you don’t live anywhere near the sea.

Helen goes in search of short cuts: aquatic engineering to make more and better ‘breaks’. Her quest takes her to Boscombe, a seaside suburb of the English coastal town of Bournemouth. The council spent £3.2 million on an artificial surf reef, which was designed to boost the wave height: lengthen the ride duration: and magnify Boscombe as a surfer dude magnet. It was already a spot known to the surfing folk of the Dorset coast but the artificial reef was going to make Boscombe a national surf destination. Unfortunately in 2010, the underwater construction of gigantic sausages of sand – covering the area of a football field - failed to do the job and the surfing is, if anything, now worse where the reef lies. Helen talks to the surfing scientist who diagnosed the reef’s ills with a GPS receiver down the back of his wetsuit, and to local surfers for their take on the Boscombe reef.

But Helen has to travel to the Basque Country in northern Spain to find what she’s been looking for. She has the most exciting surf ride of her life in a man-made lagoon, the Wavegarden, in the foothills of the Cantabrian mountains, kilometres from the ocean. Over the last decade a company formed of surfing engineers has invented a machine which summons up two sizes of perfect surf waves every minute. “That was a bigger wave, a faster wave, than I have ever contemplated surfing in the ocean,” she says in the programme after two rides in the Wavegarden (recorded with a double-bagged radio mic for the programme).

Wavegarden engineering has been exported to an abandoned slate quarry in North Wales where the world’s first surf park opened at the beginning of August. Other surf parks will follow in Texas in the United States, the Middle East and Australia, using the technology. This particular brand of artificial wave engineering might also allow surfing to graduate as an Olympic sport.

But is surfing an artificial wave in a land-locked lagoon the real thing? Surfing veterans have mixed feelings and share their thoughts on why riding the ocean is all-consuming.

In June 2015 the death of Cecil the lion was international news and a social media sensation. Yet trophy hunting of lions and other species is common in Africa. Foreigners pay big money to adorn their walls with heads and skins. Many find it abhorrent, angry that it exists at all. Hunters claim it is vital, providing money to fund conservation. With hunters claiming that a ban would be "catastrophic" for wildlife, what is the truth? Biologist professor Adam Hart explores this explosively controversial subject, talking to hunters, conservationists, lion experts and those opposed to hunting.

Trophy hunting does work in places where regular tourists are few and far between. It works too in South Africa. Private ownership and fencing, which protects wildlife from people and people from wildlife, mean that hunting and tourism generate the cash needed to maintain huge numbers of animals. Wildlife thrives because "it pays it stays".

But in Tanzania lion populations are rapidly declining. Craig Packer, a world expert on lions, says "it takes $2000 annually to maintain 1km2 of lion habitat; 300000km2 of hunting blocks need $600million. Trophy hunting pays $20million with 10-15% used for conservation". It's the only source of income but it is far too little, only slightly slowing the inevitable.

Hunting pitches emotion against evidence and sentimentality against practicality. Adam's travels reveal a complex and sometimes unpalatable tale of economics, ecology and conservation with implications that affect everyone that cares about African wildlife.

Brian Cox and Robin Ince continue their tour of the USA, as they take to the stage in LA, as they ask what happens when science meets Hollywood. They ask why so many movies now seem to employ a science adviser, whether scientific accuracy is really important when you are watching a film about a mythical Norse god and whether science fact can actually be far more interesting than science fiction. They are joined by cosmologist Sean Carroll, comedian Joe Rogan, executive producer of Futurama, David X Cohen, and Eric Idle.

The BBC’s award-winning radio science/comedy show The Infinite Monkey Cage has transported itself to the USA bringing its unique brand of witty, irreverent science chat to an American audience for the first time.

In the first of four specials, professor Brian Cox and comedian Robin Ince take to the stage in New York, to ask the question - is science a force for good or evil? They are joined on stage by Bill Nye the Science Guy, cosmologist Janna Levin, actor Tim Daly and comedian Lisa Lampanelli.

One night in 1995, PhD student Didier Queloz was running a routine test on a new detector they had just built at the Observatoire de Haute Provence in France, when he noticed something strange. They had pointed the detector, almost at random, towards 51 Pegasi, a star in the constellation Pegasus, about 50 light years from Earth. But the light from that star, which should have been constant, was in fact ‘wobbling’. Naturally, he assumed that the detector was faulty but after double-checking that it was working correctly, he and his colleagues eventually came to the only logical conclusion they could - that the light from the star was distorted by the presence of a very large object – and it was happening at regular intervals. What Queloz had discovered was the first planet outside of our solar system orbiting a sun-like star. What is more, it was massive – half the size of Jupiter, but with an orbit lasting only 4 days and with surface temperatures exceeding a 1000 degrees centigrade.

This shouldn’t be possible according to our best theories of planetary formation, and yet here it was. With their discovery published Queloz and his supervisor, Michel Mayor, had rewritten the astronomy text books and opened to floodgates. In the 20 years since that night, nearly 1800 confirmed exoplanets have been discovered, and since the launch of Nasa's Kepler Observatory in 2009, several hundred Earth-like planets have been confirmed, orbiting suns at a distance that could potentially support life. In the last of the current series of Life Changers, Kevin Fong talks to Didier Queloz about that remarkable night, its impact on science and our quest to answer perhaps the most fundamental question of all - are we alone in the Universe?
