People are fascinated by the unknown, by the possibility that there are things out there that are yet to be discovered.

We think that most of our planet has been mapped by satellites and continents have been thoroughly explored. Although scientists estimate that millions of species are yet to be discovered, these are mostly assumed to be very small animals, especially invertebrates.

Long gone are the days of famous explorers, when the borders of uncharted lands were marked with warnings such as “here be dragons”. And yet, many of us, still hope that some amazing, unexpected creatures may be hiding somewhere.

A lost Nazi gold train was discovered in Poland. At least, that’s what a couple of treasure hunters told the world last year. Like all lost treasures, the search for this one had been going on for many years, usually without success.

Every "Game of Thrones" season premiere needs its shock reveal – and season six is no different. As the name of the episode – The Red Woman – hints, this one pertains to red priestess Melisandre, to whom, it turns out, there’s much more than meets the eye (don’t worry, no spoilers ensue). Even in a series known for its complex characters and even more complicated morality, Melisandre and her motives remain surprisingly opaque. And it looks as if her story’s only just getting started.

It is unsurprising that wherever Donald Trump goes, headlines follow. But what is particularly interesting is just how many of those headlines involve the practice of journalism and journalists themselves.

The move by food group Mars to introduce a worldwide labeling scheme that categorizes its products as “occasional” and “everyday” based on their sugar, salt and fat content, is both unusual and potentially risky. The American company is behind products including Uncle Ben’s rice and Dolmio pasta sauces, though the chocolate ranges it is also known for aren’t part of this new initiative.

When we published a paper in 2013 finding 97% scientific consensus on human-caused global warming, what surprised me was how surprised everyone was.

Ours wasn’t the first study to find such a scientific consensus. Nor was it the second. Nor were we the last.
