We at Atlas Obscura start planning for Halloween early. It’s not that we’re making costumes or prepping for parties (though some of us are), it’s that we and our network of freelance writers around the world are hunting for stories. We lean hard into October. In fact, this year, we called the whole month AO Loves Halloween. But it’s never quite enough for us. We’re looking for stories like these—weird, wondrous, wicked—all year long.

Here are some of our favorite spooky stories of the year that dig into the history, science, and culture of things that send a shiver up your spine.

Why Horror Is So Damned Fun

by Samir S. Patel, Editor in Chief

Over the years science has illuminated a great deal about the biological side of fear, how our bodies prep us to run or throw a punch when there’s an immediate threat. But why we actively seek out frightening experiences as entertainment, how we react to them, and the impact they have on us, that’s a much darker forest. Editor in Chief Samir S. Patel visited the Recreational Fear Lab in Aarhus, Denmark, the only laboratory in the world dedicated specifically to understanding the fun, possibly beneficial, side of fright.

Gemma Tarlach introduces you to nature’s body snatchers, from cockroach-riding wasps to suicidal ants to spore-bomb spiders. And yes, humans are at risk from a few of them.

How Sexism Haunts the Haunted House Industry

by Sarah Durn, Associate Editor

Between nine and 12 of every 1,000 deliveries produces twins, and around four of those are identical, or monozygotic, twins. There are a lot of factors that make us who we are, but identical twins share the same raw material.
