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?

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.

Every country in the world has at least one Sign Language. Each is a complete communication system with its own grammar, lexicon and structure and has evolved over centuries, just like their verbal counterparts. Although many have legal status under disability legislation, only four have been given the status of a recognised official language. But not everyone who is deaf uses sign language, and not everyone who uses sign language is deaf. Some deaf rights campaigners say that Sign language is a signifier of belonging to a Deaf community, with a rich cultural legacy. But does the choice to use hearing aids and cochlear implants to help use verbal language really mean a rejection of deaf culture and a deaf identity?

If the US is going to build a wall on its border with Mexico, it’s going to take a lot of concrete - millions of tonnes, in fact. But this is a tiny amount compared with China’s concrete use. It’s often said that China used more concrete between 2008-2011 than the US did in the whole of the 20th Century. It sounds astonishing - and is it true? Wesley Stephenson finds out.

Is it really true our attention spans are getting shorter in the always-connected world of social media, smartphones and hyperlinks? The statistics say that the average attention span is down from 12 seconds in the year 2000 to eight seconds now. That's less than the nine-second attention span of the average goldfish. But the statistics are not all that they seem - and neither is the received wisdom about goldfish.

In the wake of Donald Trump’s claim that three million people may have voted illegally in last year’s presidential elections, we scrutinise the American electoral system and the work of the Electoral Integrity Project that suggests North Carolina is on a par with Cuba.

A disturbing rumour’s been trending online recently - of a paedophile ring on YouTube. BBC Trending investigates and debunks another internet myth.

In his first TV interview as US President, Donald Trump claimed that torture “absolutely” works and said the US should “fight fire with fire.” But what evidence is there that torture is an effective method of obtaining valuable intelligence? And, can the use of torture ever be justified? Becky Milligan hears from a former interrogator who worked at the Abu Ghraib prison in Iraq, a former political prisoner who was tortured in the notorious Evin prison in Tehran, and a neuroscientist who has studied the effects of torture on the brain.

There are two things that you can be sure of in January and both of them make the More Or Less team want to scream. Firstly, Oxfam put out their ‘x number of billionaires hold the same wealth as the poorest half of the world’ statistic, a comparison which, as said in the past, does not make sense. The second head-banger is ‘Blue Monday’, the formula that supposedly tells us that the third Monday in January is when people are at their saddest. Each year it appears on different press releases promoting different products, but there is no science to it at all.

Could you forgive the person who killed your child or who raped or tortured you? Some crimes, some events are so awful, so cruel, it’s impossible to imagine ever being able to say to the wrongdoer, ‘I forgive you’. Mike Williams hears the stories of those who have experienced unimaginable pain and suffering at the hands of others. And discovers what it feels like to turn anger and desire for revenge against the perpetrators into compassion and understanding for them. What does the act of forgiveness mean to the offender? Contributors include Kemal Pervanic, a survivor from the Omarska concentration camp during the Bosnian war, a rape survivor and a woman whose ex-husband killed her two children.

After two decades working in development, Claire Melamed is ready to reveal a secret about her work. Many of the numbers that lie behind life-and-death decisions in developing countries are, as she puts it, “a bit shaky”. If you don’t know how many people live somewhere and who’s dying when of what, you can’t make well-informed decisions to help them. Now she and others are working to change that by getting better data and using it smarter. We hear what that means in practice and the story of Justice Aheto, whose award-winning mathematical models could also be life-saving for malnourished children in his native Ghana.

Four of the biggest stories on the internet this year divided opinion around the world. We discuss the most popular memes of US Elections, the highlights of the EU referendum in the UK, why people around the world were scared of clowns and how live streaming made its mark on the digital world.

People took to the streets in India to protest about the government’s decision to withdraw R500 R1,000 notes. But despite the uproar the Prime Minister Narendra Modi has insisted he has the support of the people after a survey, carried out on his very own mobile app, found that the decision was supported by more than 90% of respondents. But he’s been criticised for leading and confusing questions designed to get a particular outcome.

When Filipino President Rodrigo Duterte swept to power in May, many believed social media played a major role in his victory. But some allege his supporters used trolling and intimidation, in addition to clever campaigning, to bolster his position. Since winning, he has waged a war on drugs, leading to allegedly thousands of extra-judicial killings.

And, why don’t we understand how the female orgasm works? After years of scientific research, the male body is understood but when it comes to how women work, we are a long way behind. It appears research has been hindered by the assumption that the female body works in the same way as the male body and that for women, arousal is all in the mind. Researchers are slowly correcting these assumptions and making surprising discoveries.

Are you sexist, racist or ageist? Even if you think you’re open-minded, the chances are, you’ll be judging people and situations without even realising.
