Nature.

In a experiment, I don't know yet.

Why is Blight so far?

Like, it sounds so simple.

They had no idea.

But now the data's people.

I find this not only refreshing, but at some level astounding.

Nature.

Nature. Nature. Welcome back to the Nature Only nature.

Welcome back to the Nature podcast.

This week on the show, we're probing protons and learning how to maintain a healthy lab environment.

Plus, we'll be finding out how to make sense of mystery microbe genes.

This is the nature podcast for the 17th of May 2018. I'm Charmany

Bundell. And I'm Benjamin Thompson. First up this week, reporter Lizzie Gibney is peering into

the heart of matter. Here at nature, we talk a fair amount about dark matter. But what about boring old ordinary matter?

It may account for just 15% of material in the universe, but it's a pretty important part. After all,

it makes up everything we can see, from stars to us. And even though it's visible, it still hides

plenty of mysteries. The bulk of the matter

in the universe is made up of protons. But what makes up the proton? That's where things get a little

fuzzy. Protons are far too small to see under a microscope, around 100,000 times smaller than an atom.

So instead, physicists study protons by pinging high-energy electrons off them.

These experiments show that each proton must consist of more fundamental particles,
