"Lordy, I hope there are tapes," said an exasperated James Comey in his testimony before the Senate Intelligence Committee on June 8. Comey's desire reflects a familiar one for individuals accused of lying when the stakes are high. The former FBI director wished for tapes because, in our society, audio and video recordings serve as a final arbiter of truth. He said, she said always loses to what the tape shows.

Facebook is due to start hiding posts from people who spam users' news feed with clickbait, sensationalised and misinformative articles. In a statement, the social media giant said it was making the update "to reduce low quality links" in users' news feed. Facebook said it carried out research which showed that a small group of users were "routinely sharing vast amounts of public posts per day", which was effectively spamming people's feeds. The study showed that the same people, who were sharing vast amounts of public posts, were also sharing low quality content. As a result of the research, Facebook said it would "deprioritise" posts being shared from those accounts.

The country was awash with national pride. Union Jacks proudly flying at full mast across most British streets and a feverish party atmosphere, as we hosted arguably the best ever Olympic Games. During the games, we witnessed the prominent rise and rightful public recognition of the athleticism of disabled athletes, competing in the Paralympics and Special Olympics. Tanni Grey-Thompson, Ellie Simmonds and Lee Pearson are now just as likely to be debated as Britain's best Olympians from those games, alongside Mo Farah and Bradley Wiggins, amongst friends down the pub. Whatever stigma previously existed was smashed to bits, as our heroic athletes brought home gold medal after gold medal. As a result of the games, we are now seeing society becoming far more understanding and inclusive of the disabled community, but with the United Nations reporting that around 15% of the world's population suffer with some type of disability, there is a growing feeling that we need to do more, to help make the lives of people with disabilities easier.

Artificial intelligence (AI) is one of the biggest commercial opportunities in today's economy and could grow UK GDP by 10 percent by 2030, according to a report by professional services firm PwC. The report believes that AI will transform the productivity and GDP potential of the UK, but there needs to be sustained investment in AI technology to make this happen. It says AI could have this impact by bringing about more consumer choice and more affordable, bespoke goods over time as a result of the new technologies. As well, efficiency gains through productivity will facilitate product innovation, which should lead to gains in the UK's GDP. In addition, it notes that the UK is well-placed to benefit from the shift towards automation thanks to having strong foundations in the technology already.

Agriculture is the industry that accompanied the evolution of humanity from pre-historic times to modern days and fulfilled faithfully one of its most basic needs: food supply. Today this still remains its core mission, but it's integrated in a more complex than ever mechanism driven by multiple sociological, economic and environmental forces. This $5 trillion industry representing 10 percent of global consumer spending, 40 percent of employment and 30 percent of greenhouse gas emissions continues to keep pace with world's evolution, changing tremendously over the past years. Digital and technological advancements are taking over the industry, enhancing food production while adding value to the entire farm-to-fork supply chain and helping it make use of natural resources more efficiently. Data generated by sensors or agricultural drones collected at farms, on the field or during transportation offer a wealth of information about soil, seeds, livestock, crops, costs, farm equipment or the use of water and fertilizer.
