The Inquiry

Ever since Donald Trump took office in 2016 his critics have been focussed on getting rid of him. As the Mueller probe into Russian collusion in the presidential election heads into its last six months, several members of President Trump’s inner circle have been convicted of serious crimes. For some, it’s only a matter of time before Trump himself is implicated. For others, the evidence so far is simply not substantial enough. With Democrats now in control of Congress, the votes are there to impeach Trump and send him for trial in the Senate. But what would it take to get the two thirds majority needed to remove him from office?

Human activity is sending animals and plants extinct. But there is a fightback going on. Scientists all over the world are coming up with radical solutions to save them - from transplanting polar bears, to “de-extincting” a very strange frog. And experts say each one of us can make a difference. So is it too late to save the planet, or can we stop a mass extinction?

This week we’re looking at nothing less than the state of life on earth. The planet has seen mass extinctions before, periods of widespread and dramatic species loss. Some now fear human activity is driving another one: land cleared for farms, homes and roads; waters filled with pollution and emptied of fish; skies choked with gasses causing climate change. But does it add up to a mass extinction? In the first of a two-part series, we examine the evidence of species loss and compare it with the geological record.

Millions of us take a vitamin tablet every day - how did they become so popular? We follow the rise and rise of vitamins from their discovery just a century ago, to the multi-billion dollar market of today. The story of how the vitamin supplement entered our daily lives takes us from the targeted guilt-tripping of concerned mothers, to the use of vitamins as a weapon against the Nazis, via a plan for vitamin doughnuts. Experts question whether most of us need to take them at all – so how did we get hooked on vitamins?

#MeToo became viral following allegations of sexual harassment and violence at the hands of Harvey Weinstein. Now women and men in their millions around the world have been mobilised by the hashtag to share their stories of abuse.
