In 1990, fossil collectors in South Dakota stumbled across a dinosaur that turned out to be a really big deal. Not just because it was a T. rex – basically the most popular dino out there – or because it ended up in Chicago’s famous Field Museum… but because of the number of bones it had.

By overcounting how much carbon their forests suck up, and undercounting how much carbon their industries release, countries undercount their total carbon emissions.

Meteorite hunters don’t search for meteorites in the places most frequently peppered by them – they go to Antarctica instead, because that’s where they are easiest to find.

In the future, humans will likely die of a very different suite of causes than we do now, thanks to advances in healthcare, an aging population, and changes in the environment.

Many of the greatest biological dispersal events in history likely happened because animals inadvertently traveled across the oceans on floating debris.

Elephants might be strong, but they are weak compared to ants because ants have certain advantages that allow them to outlift their larger competitors.

PFAS - also known as the “forever chemicals” we use in all sorts of household products - are able to cause all sorts of health problems without ever really reacting with anything.

Because eclipses are powerful and frightening events, ancient cultures went to great lengths to understand eclipses, leading to remarkably accurate predictions and helping invent the science of astronomy.

We've long known that animal pollination is an important way plants reproduce on land, but we're only JUST finding out animals also pollinate plants underwater.

Hurricane path prediction seems straightforward, until it is not – that’s because hurricanes can encounter atmospheric effects that turn their paths into erratic nonsense.

Sewers are a great way to make pooping safe, but they’re not always the right solution because they require specific resources that many places just don’t have.
