In 2019, we began investigating the disappearance of Dr. Ruzha Ignatva.

I believe we are a very special network.

A scammer who stole billions from investors around the world.

She's on the FBI's 10 Most Wanted list.

And now, we have some unmissable updates. She has money and when you have

money, you have power. Join me, Jamie Bartlett, as the hunt for the missing crypto queen continues.

Listen first on BBC Sounds.

My favourite author, Kurt Vonnegut, wrote a book called Cats Cradle, and in it, a bunch of

scientists create a form of ice more energetically stable than liquid water at room temperature.

So any liquid water in contact with this fictional ice nine turns to ice two. It doesn't end well. It turns out that

in real life, scientists are still discovering new forms of this wonderful solid water. You'd think

that a molecule made of one atom of oxygen bound to two atoms of hydrogen, so a tiny boomerang-shaped thing would arrange itself in a limited number of ways.

But no.

Chemists have discovered 20 different kinds of ice

and say that there may be more, theoretically,

as many as 74,963, different ways of putting together a block of ice.

They will all have subtly different properties and conditions for existing.

But, unlike Kurt Vonnegut's fictional Ice 9, there's no variance to freeze life on Earth,

just thousands of ways to add a cooling element to your cocktail.

I'm Marnie Chesterton from the BBC World Service.

This is Unexpected Elements.
