The major film The Iron Lady features a critically acclaimed performance by Meryl Streep as British Prime Minister Margaret Thatcher – The Iron Lady of the Western World. From her humble beginnings as a Grocer’s daughter from Grantham, Margaret Thatcher fought her way through the murky world of politics, the sexist prejudices of the Conservative Party elite and the scepticism of the British electorate to become the greatest British Prime Minister since Winston Churchill. Although Margaret Thatcher broke down the barriers and became a pathfinder for a new generation of women in politics, she was not averse to using her good looks and sexuality to help convince other leaders that hers was the right course of action. It was not for nothing that French Premier Francois Mitterrand said that she had ‘the eyes of Caligula and the mouth of Marilyn Monroe’. But most of all Margaret Thatcher was a conviction politician. Never scared of criticism or negative opinion polls, she fought for what she believed was right and just: whether that was fighting against the Argentine invasion of the Falklands

How much should we know about an unborn child—and what happens when prenatal science forces parents to make impossible decisions? Prenatal Diagnosis: Pregnancy Under the Loop explores the rise of prenatal diagnosis, from ultrasound and chromosome testing to fetal surgery, genome sequencing and artificial intelligence. Through doctors, researchers and families in France and the Czech Republic, the documentary examines how pregnancy has changed now that the fetus can be seen, measured and diagnosed before birth. For some parents, these technologies bring reassurance and hope. For others, they lead to devastating uncertainty, difficult decisions and profound ethical questions about disability, abortion, normality and the idea of the “perfect” child. As medicine becomes able to reveal more than ever before, are parents, and society, prepared for everything science may tell us? ------- Chapters ▷ 00:00 – How Prenatal Diagnosis Changed Pregnancy ▷ 03:03 – The Ultrasound Revolution and the Visible Fetus ▷ 06:51 – When a Routine Scan Reveals an Abnormality ▷ 10:20 – Parents as “Moral Pioneers” ▷ 13:25 – Disability, Normality and the “Perfect” Child ▷ 14:36 – Genetics, Chromosomes

In the final episode of Myth or Science, microbiologist Jennifer Gardy investigates one of humanity’s most overlooked and misunderstood substances: poop. Though commonly dismissed as disgusting waste, feces may contain remarkable clues about our health, our environment, and even the future of sustainable technology. Through a series of surprising experiments, Jennifer tests whether flushing a toilet spreads fecal bacteria around the bathroom, whether colon cleanses improve health, and whether visible corn in stool is evidence of poor digestion. She also explores what the shape, smell, frequency, and buoyancy of stool can reveal about the human body. Beyond personal health, the episode uncovers the wider scientific potential of waste. Researchers analyse sewage to track the health of entire communities, specially trained dogs locate orca feces to help protect endangered whales, and engineers transform sewage sludge into clean drinking water and energy. Jennifer even investigates whether dogs align themselves with the Earth’s magnetic field while defecating and how fish waste helps create tropical beaches. ------- Chapters ▷ 00:00 -The Hidden Power of Poop ▷ 01:38 - The Toilet Plume Experiment ▷ 05:44
