Prof Andrea Sella on the shifting image of the scientist in popular culture, from Victor Frankenstein to Iron Man via victorious post-war boffinry and megalomanical Bond villainry. The monster unleashed by Mary Shelley in her 1818 tale of gruesome gothic horror was in many senses not the creature itself, but the image of its careless creator. The recklessness of the lone scientist whose blind ambition fails to foresee the societal and practical consequences of his discovery or invention. Throughout the last 150 years, the scientists in our science fictions have embodied the contemporary societal attitudes to science itself, sometimes in celebration, but often as a cartoon of our fears. At the same time professional scientists and science communicators have tried to share their work with wider audiences in an effort to democratize and enliven the endeavour. These two approaches haven't always been in synchrony. Presented by Prof Andrea Sella Produced by Alex Mansfield First broadcast on Saturday 9 October 2021.

Why are some people left-handed, whereas the majority are right handed? Rutherford and Fry revisit The Sinister Hand episodes to further investigate handedness in humans and animals. They considered cockatoos, chimpanzees and Hannah's dog, Molly, to discover that humans are unique, with just one in ten of us being left-handed. They ask if there is an evolutionary reason for just 10% of the human population being southpaws Hannah talks to primatologist Prof Linda Marchant from Miami University about Neanderthal teeth and termite fishing. Adam consults handedness expert Prof Chris McManus from University College London. He's been trying to track down the genes responsible for whether we're right or left handed. And what about left-handed brains or eyes or molecules? Prof Andrea Sella explains handedness, or chirality, at the molecular scale and why when we consider Thalidomide, something seemingly so trivial can be extremely important. They also explore the left-handed brain. Some researchers point to a link between left-handedness and impairments like autism or dyslexia. Others claim that lefties are more creative and artistic. So what's the truth? The team consults Professors Sophie Scott, Chris McManus and Dorothy Bishop to find out. This episode is an updated version of two earlier broadcast episodes.

The Periodic Table How well do you know your Fe from your Cu, and what the heck is Np?? Brian Cox and Robin Ince are joined by comedian Katy Brand, Prof Polly Arnold and Prof Andrea Sella to celebrate the 150th anniversary of Dmitri Mendeleev's great achievement. They find out how scientists first realised that the elements that form the ingredients that make up our planet , are able to be organised in such a logical and ordered way, and whether its still a useful tool today. They also discover why one of the guests has been called the Free Solo equivalent of chemists because of the skill and danger involved in their work. Producer: Alexandra Feachem

A story of sorrow and comfort today, as Doctors Adam Rutherford and Hannah Fry investigate two mysteries sent in by listeners. The Psychic Tear Edith Calman challenges our scientific sleuths to answer the following question: “What is it about extreme pain, emotional shock or the sight of a three-year-old stumbling their way through an off-key rendition of Away in a Manger that makes the brain send messages to the lacrimal glands to chuck out water?" Hannah discovers how the eye produces tears, with the help of Dr Nick Knight. Broadcaster Claudia Hammond, author of Emotional Rollercoaster, describes why Darwin experimented on his children until they cried. And, Adam watches a tearjerker to take part in a psychological study, but ends up getting angry instead. The Tea Leaf Mystery The team examine how to make the perfect cup of British tea, in response to Fred Rickaby from North Carolina: "When we are preparing a cup of tea and the cup contains nothing but hot, brewed tea we need to add milk and sugar. My wife always adds the sugar first, stirs the cup to make sure it is dissolved and then add the milk. So, is that an optimum strategy for adding milk and sugar to a cup of tea?" Adam consults Prof Andrea Sella from University College London about the chemistry of tea. Hannah visits a tea factory in Kent where Master Blender Alex Probyn teaches her an unusual method for tasting tea. They conclude with the most important question: should you add the milk first or last? And, can tea professionals really tell the difference? If you have any everyday mysteries for the team to investigate using the power of science, please email curiouscases@bbc.co.uk Producer: Michelle Martin Image: A woman holds a cup of tea, Credit: Thinkstock

Today the team examine the chemistry of tea, in answer to the following question sent in by Fred Rickaby from North Carolina: "When we are preparing a cup of tea and the cup contains nothing but hot, brewed tea we need to add milk and sugar. My wife always adds the sugar first, stirs the cup to make sure it is dissolved and then add the milk. So, is that an optimum strategy for adding milk and sugar to a cup of tea?” Adam consults Prof Andrea Sella from University College London about the perfect formula for a cup of tea. Inside his tea factory in Kent, Master Blender Alex Probyn teaches Hannah an unusual method for tasting tea. Most importantly, the duo discovers whether you should add milk first or last. But can tea professionals really tell the difference? If you have any questions for Drs Rutherford & Fry to investigate send them to curiouscases@bbc.co.uk Presenters: Hannah Fry, Adam Rutherford Producer: Michelle Martin

Radium, polonium and radon may be names to make your hair stand on end, but are they actually useful for anything? And is our fear of them overbaked? Laurence Knight gets the chemistry rundown from Prof Andrea Sella of University College London at a hospital that used to treat cancer with radiation. Al Conklin of the Washington State Department of Health explains how we are still dealing with the world's early Twentieth Century craze for all things radioactive. Edwin Lane reports from Finland on how the country's geology and climate conspired to fill their houses with a radioactive gas. Plus, we hear from Prof Norman Dombey, a key expert witness in the public enquiry into the murder of Alexander Litvinenko.

Rare and toxic, beryllium can do serious damage to your lungs. Presenter Laurence Knight explores whether and how we can make use of this metal safely. Prof Andrea Sella of University College London explains why beryllium's surprising scarcity is the very reason it can be so harmful to the body. Gianna Palmer reports from the Hanford nuclear site in Washington State on this chemical element's intimate and poisonous history in the US nuclear weapons programme. And we hear from IBC Advanced Alloys, a company that claims to have a novel, cheap - and safe - way of producing aeroplane parts out of beryllium-aluminium.

Titanium is the magic metal that made possible the mass production of plastics and paints, as well as buildings that clean both themselves and the air around them. Presenter Laurence Knight heads to the Ineos oil refinery in Grangemouth, Scotland, to see how just a smidge of a titanium-based catalyst transforms a type of natural gas into the stuff of food packaging, bottles and car bumpers. He hears from Prof Andrea Sella why most of us spend our lives surrounded by titanium without even realising it. And Brian Pickett of pigments manufacturer Cristal explains why his company has been painting various bits of London to further the fight against city smog.

These powerful chemicals are essential to obtain the minerals that build our world, the fertilisers that feed the planet, and the fuels that propel our vehicles - as presenter Laurence Knight discovers on a trip to the Ineos Grangemouth oil refinery in Scotland. But while most traditional acids are based on the power of hydrogen ions, Prof Andrea Sella of University College London explains that many modern industrial "acids" do not, and come in startlingly unexpected forms such as powders. Many of the most corrosive acids are very tricky to contain, resulting in the occasional nasty accident, as chemical engineer Keith Plumb explains. Also, Justin Rowlatt has a report on acid attacks in southern Asia in which he speaks to campaigner Selina Ahmed of the Acid Survivors Foundation on how Bangladesh has tackled the problem.

Why is oxygen essential to steelmaking, how do you extract it from the air, and can you inhale too much of it? Answering these questions leaves presenter Justin Rowlatt almost breathless. Prof Andrea Sella demonstrates the convenience and power of this bulk chemical, whilst Laurence Knight heads to BOC's air separation unit in Fawley to see how it is mass produced. Meanwhile Justin climbs a mountain, scuba dives and pedals like mad on an exercise bike inside a low oxygen chamber. But it's all in the name of science, as husband-and-wife medics-cum-mountaineers Denny Levett and Mike Grocott explain.

Stronger and more durable than steel, this glamorous metal crops up in sportscars, hip replacements and jewellery - but a new chemical process hopes one day to make it as common as steel. Prof Andrea Sella explains why this relatively widespread chemical element is so difficult to extract from its ore. Presenter Laurence Knight then heads to Yorkshire, where metallurgy pioneers Metalysis are trying to commercialise a novel way of doing just that - the so-called FFC Process. We also visit Epsom hospital, south of London, where orthopaedic surgery head Philip Mitchell explains why titanium makes such great bone implants, and Philip Dewhurst of mineral consultancy Roskill casts doubts on whether titanium will ever become cheap and ubiquitous, at least in his lifetime.

The “element of life” also makes the air that we breathe a perilous and costly atmosphere in which to operate. Prof Andrea Sella of University College London provides presenter Justin Rowlatt with a characteristically striking argument for why oxygen is so “incredibly dangerous”, and how its advent turned Planet Earth into a snowball. Pawanexh Kohli, in charge of India’s national cold chain strategy, explains over a cup of chai why the oxygen needs of fresh vegetables and fresh meat are very different. Physics polymath Baldev Raj unpicks the mystery of Delhi’s 1,600-year-old iron pillar, and explains just how damaging rust and corrosion can be. And former “smoke-jumper” Frankie Romero explains the mesmerising attraction of wildfires, and why stamping them out isn’t always a good idea.

Copper has long been the metal of electricity generators and wiring. But presenter Justin Rowlatt asks whether new technologies herald the death of the old-fashioned electricity grid. Prof Andrea Sella of University College London explains the special properties of element 29 of the periodic table that mean that half of the world's mined copper is used to conduct electricity. Justin travels to the rapidly growing Indian city of Gurgaon to ask Jasmeet Khurana of solar consultancy Bridge to India what his government's plans to increase solar power a hundredfold mean for the best way to build the country's electricity grid. Electricity entrepreneur Simon Daniel of Moixa Technology argues that solar power and battery technology could transform the century-old debate between Tesla and Edison over AC vs DC power. And Zolaikha Strong of the Copper Development Association says the transition to renewable energy means the world will still need plenty more of the metal.

LED lighting, solar power and lasers are just some of the electronics revolutionised by two obscure chemical elements - gallium and indium. Laurence Knight hears from Mike Simpson of Philips why we will only need to replace our lightbulbs once every two decades, and travels to Sheffield University where research centre head Jon Heffernan explains what on earth III-V materials are and why making an LED is like baking a pizza. Meanwhile chemistry stalwart Prof Andrea Sella of UCL demonstrates these two metals' surprisingly buttery melt-in-the-mouth properties.

Lithium is the electro-chemical element - big in batteries and bipolar disorder. Over two decades it has shot from obscurity to become almost synonymous with the way we power our gadgets. Presenter Justin Rowlatt hears from chemistry powerhouse Prof Andrea Sella of University College London about what makes lithium so light and energetic. We hear from Gideon Long in Chile, who visits the world's richest source of lithium in the Atacama Desert, and about how neighbouring Bolivia believes it will dominate supply if demand for this alkali metal continues to see double-digit growth. Justin speaks to Prof Nigel Brandon of Imperial College, an expert on cutting-edge battery research, about whether this week's element can ever realistically hope to challenge a can of petrol as the best way to power a car. And we hear from clinical psychologist Kay Redfield Jamison of Johns Hopkins University about the literally life-saving role lithium has played for sufferers of bipolar disorder - including herself.

Prof Alice Roberts goes Inside Science this week to discuss the science behind artificial reefs. The 70 concrete blocks around Gibraltar are currently causing a diplomatic controversy as the Spanish government claim they restrict commercial fishing. We look at how artificial reefs are made and what effect they have on the marine environment.Bees have faced multiple dangers in recent years, from pesticides to parasites. Reporter Roland Pease visits a team at the University of Bath who are putting beehives into a CAT scanner to discover whether they can help breed bees that are more resistant to disease.Humans are special; our uniquely evolved feet testify to that, allowing us to walk upright. At least, that's what anatomy students have been taught for the past 70 years. Research published his week by a team at the University of Liverpool shows that our feet are much more ape-like than we thought. And some of us may have more 'apey' feet than others.Finally, this week Prof Andrea Sella from University College London shows us his instrument - an NMR spectrometer. This magnetic beast determines not only the chemical composition of molecules, but also their 3D structure.
