Chemical reactions are the backbone of modern society: the energy we use, the medicines we take, our housing materials, even the foods we eat, are created by reacting different substances together. If we zoom in, it’s the atoms within these substances that rearrange themselves to give rise to new substances with the properties we need. However, chemical reactions are far from perfect. They're often inefficient and their waste products can be harmful to the environment. Getting to grips with what goes on at the scale of individual atoms has long been a sticking point. Dame Pratibha Gai has spent much of her career pioneering novel microscopes to bring this seemingly inaccessible atomic world into sharp focus. Now Emeritus Professor of Chemistry at York University, her microscope, known as the environmental transmission electron microscope, is housed in labs around the world. It allows scientists, like herself, to observe chemical reactions in real-time, in exquisite atomic detail, and tinker with them to create products that are not only better for all of us, but also the environment.

Donald Trump has suggested the US could deploy troops to Nigeria or carry out air strikes to stop what he called the killing of Christians by Islamist insurgents. Unfounded claims of a Christian genocide in Nigeria have been circulating in American right-wing religious circles for months. A Nigerian presidential adviser said jihadists in the Muslim-majority north of the country were attacking all religious communities, but that Abuja would welcome US help in tackling the Islamist insurgents. Also: the sole survivor of the Air India plane crash has told the BBC that he feels he is the luckiest man alive. Officials in Iran warn the main source of drinking water for residents of Tehran is at risk of running dry within two weeks. Flight delays continue across the US, as air traffic controllers working without pay due to the government shutdown are now calling in sick.

Kurdish designer Lara Dizeyee is preparing a couture collection for Milan Fashion Week. Dizeyee fled Iraqi Kurdistan as a child, grew up in the US, and later returned to Erbil. Her designs draw on traditional Kurdish dress - layered garments, capes, and ornate headpieces - reimagined as bold evening wear. Her work is celebrated in Kurdistan, across the diaspora, and in the Arabian Gulf. Yet despite her growing profile, she lacked the funds to stage a show on the scale Milan demands. Arts journalist Melissa Gronlund follows her as she secures backing and races against time to source fabrics, sketch and sew designs, and collaborate with Kurdish artisans on jewellery and bespoke accessories. More than 30 outfits are completed and packed into suitcases carried by her extended family. On the big day, Dizeyee fits each model and navigates last-minute crises - models too short, earrings that won’t fit, designs that misfire. But as the models walk out in her reimagined Kurdish looks, the emotion in the room is unmistakable. And in that final moment, as the Kurdish flag is symbolically recreated on the runway, Dizeyee presents her culture to the world.

Helen goes further than she meant to, and Jolene plays matchmaker.

British police say there is nothing to suggest a mass stabbing incident on a train on Saturday was a terrorist incident. Doctors continue to treat seven passengers, two of whom have life-threatening injuries. Armed police arrested two suspects at Huntingdon station in Cambridgeshire, where the train made an emergency stop after terrified passengers alerted the crew. Also in the programme: we'll speak to Nigeria's presidential adviser after US president Donald Trump threatened to take military action to protect the country's Christian population; and the wartime message in a bottle found ashore after one hundred years.

In the UK, counter-terrorism police are leading an investigation into a mass stabbing on a train near Huntingdon in Cambridgeshire. Nine people are in critical condition after an attack described by witnesses as ‘like a horror film’ with passengers trying to flee through carriages and barricading themselves in bathrooms. Armed officers boarded the train and arrested two men at the scene. Also: President Donald Trump threatens military action in Nigeria, saying an attack would be ‘fast, vicious and sweet’, after accusing the government there of allowing mass killings of Christians. Spain’s foreign minister has offered one of the country’s clearest acknowledgements yet of the brutality of the sixteenth-century conquest of Mexico, and we hear from Jamaica, where Hurricane Melissa has killed at least nineteen people and left hundreds of thousands without food, power or clean water.

Networks of bots - automated social media accounts - have been found to be targeting European elections including, in the last year, those in Moldova, Poland and Germany. But could their real intention be to tie up news organisations with fact-checking? Damien Sharkov from BBC Monitoring has been looking at how they operate. Earlier this year, news reports circulated online that a Vietnamese-American scientist called Anh Duong had a hand in creating the bombs used by America in its June airstrikes on Iran. Those reports turned out to be untrue, but Thuong Le from BBC Vietnamese has the real story of the chemical engineer known as 'the Bomb Lady.' In India, pigeons are a much-loved part of city life for many, but a health risk for some.Sumedha Pal has the story.
