What is #QAnon?

A protest against “manspreading” went viral in Russia – but is it Russian propaganda? Activist Anna Dovgalyuk denies that she staged a stunt where a woman was filmed throwing diluted bleach at the crotches of men whose legs were sprawled out over multiple seats on the St Petersburg Metro. But media reports suggested one of the men was an actor, and a European Union website has described the film as “staged Kremlin propaganda”. So, is it real or just a hoax? And how does it fit into a larger pattern of Russian social media bots and trolls stoking culture wars online? How do you measure a country’s generosity when it comes to overseas aid? We crunch the numbers and talk to Brad Parks from research lab Aiddata about aid donations from some of the world’s more secretive countries.

In July 2018, a disturbing video began to circulate on social media. In it two women and young children are shown being led at gunpoint by a group of soldiers. The captives are blindfolded, forced to the ground and shot 22 times. The government of Cameroon initially dismissed the video as ‘fake news’. But through open-source investigations – examining details such as buildings, shadows, and uniforms – BBC Africa found that the blame lay squarely on Cameroonian Forces. From the 10th July to the 31st of October 1940 the skies above Britain were a battle zone. The German Luftwaffe launched large scale attacks aiming to reach London, they were held back and ultimately defeated by the Royal Airforce which included many nationalities. The bravery of the pilots – known as ‘The Few’ - cannot be disputed but is it really true that the average life expectancy of a spitfire pilot during the Battle of Britain was just four weeks, as is often claimed. Tim Harford and Lizzy McNeill look into the statistics and consider which of the armed forces had the highest death rate. Thanks to our TVs and smartphones we are bombarded 24/7. Those whose job it is to care – doctors, nurses, mothers even – face even more relentless demands on their compassion. Until one day some feel they cannot go on anymore. We are all vulnerable to compassion fatigue – whether we are unable to deal with more bad news, or to care for our patients and children. But why do we get it? Why do we stop caring? And what is the impact on society when people just switch off and tune out?(Photo: A still from the video showing the murder of women and children by Cameroonian soldiers)

Why are some Russians put on extremist watch lists for saving or posting memes online? Maria Motuznaya was investigated by police after saving edgy memes on her account on the social network VKontakte. Hundreds of Russians are being targeted for using memes declared to be racist, offensive or against the Russian Orthodox Church. People on the list have their bank account frozen and some face criminal charges. Will a blogger’s campaign make a difference? Are you more chimp or Neanderthal? We often hear scientists talking about how we are related but what’s the difference between 96% similarity and sharing 20% of our DNA, and do some of us literally have pieces of Neanderthal within us?

Facebook’s dream of a more open and connected world has turned into a nightmare in Myanmar. The price of a smartphone SIM card dropped from around $200 to $2, and Facebook quickly became the app of choice, but it failed to control hate speech against Rohingyas and had very few employees who could read Burmese. What, following criticism in a UN report, is it doing now? Is one particular model of car really the safest on the road in the UK, and how can new technology reduce road accidents round the world? Have you ever been captivated by a book, full of stories you never knew, revelled in that new knowledge …and then forgotten it all? If the answer is yes, take heart; you are not alone. Sandra Kanthal asks why do we remember some facts easily, and but let others slip away, completely forgetting the things we’ve learned.Photo: Rohingya refugees pictured in August 2017.
