BBC Trending: Why are some Americans yelling at clouds?On 4 July, just hours after flash floods hit the US state of Texas, killing more than 130 people, social media was inundated with unfounded theories about the causes of this tragedy. The main allegation was that the extreme rainfall was somehow man-made, with many users blaming Rainmaker, a weather modification company based in California. These baseless claims were quickly debunked by scientists. And yet, online, calls for the company’s CEO, Augustus Doricko, to be arrested, punished - or, more sinisterly, executed - continued to multiply. Suggestions that sinister forces may be controlling the weather by spraying chemicals in the atmosphere may have once been the preserve of niche websites and forums. Not anymore.As several US states consider banning weather modification and geoengineering, BBC Trending investigates how fringe conspiracy theories have gone mainstream.

Europe’s largest herd of wild horses, in north-west Spain, is under threat. Numbers have halved in the last fifty years. Now around ten thousand wild horses roam freely in the hills and mountains of Galicia. But they are facing a number of challenges, not least the loss of their habitat and the threat from their main predator, wolves. There are also legal demands imposed by the regional government which have placed added financial burdens on the local people who, in effect, “own” these horses. And yet Galicia’s wild horses have been an integral part of the local culture for centuries, particularly during annual festivals known as “rapas das bestas,” the shearing of the beasts. The horses are also known as engineers of the landscape, credited with boosting the local flora and fauna and with helping to control forest fires.John Murphy travels to Galicia to hear what is happening to these extraordinary animals and why they are so important.This episode of The Documentary comes to you from Assignment, investigations and journeys into the heart of global events.

Russian soldiers were told that they would be the country's 'new elite' by President Putin. But many of them have reported being robbed and scammed out of the money that they earned fighting on the Ukrainian front lines. They also face mental health problems, and post-traumatic stress disorder after months or years at war, but suitable treatment is scarce and hard for them to find. BBC Russian's Sergei Goryashko has been looking into the soldiers who have been robbed and scammed, whilst Sofya Volyanova has spoken to the people in Russia attempting to treat soldiers for PTSD and depression. South Korea banned dog meat in the country last year, and the practice will be entirely phased out by 2027 ending a generations long practice.
