Summary

Learn about how scientists discovered that Venus flytraps can store short-term “memories,” why you shouldn't use real-time updates when waiting for the bus, and how epigenetics can make your DNA change within your lifetime.

Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Curiosity.com.

I'm Ashley Hamer.

And I'm Natalia Reagan.

Today you learn about how scientists discover that Venus flytraps can store short-term memories,

0:14.4

while you shouldn't use real-time updates from waiting for the bus,

0:17.6

and how epigenetics can make your DNA function differently within your own lifetime.

0:22.1

Let's satisfy some curiosity.

0:24.0

If you're in the market for a new favorite plant,

0:27.0

let me present the Venus Fly Trap for your consideration.

0:31.0

This charismatic carnivore has it all, an appetite for insects and

0:34.9

spiders, super sensitive trigger hairs, and a trap that can snap shut in a tenth of a

0:40.4

second. If you aren't sold, there's one more standout quality. The Venus fly trap

0:45.1

doesn't have a brain, sorry plants, but it does have a short-term memory and

0:50.0

researchers have finally figured out how it works.

0:53.0

See, those sensitive hairs are what trigger the plant to close its trap.

0:57.0

But it wouldn't be smart for a Venus fly trap to chomp down every time one of its trigger hairs is activated. There would just be too many

1:04.3

false alarms. That's why the plant has evolved a policy. It only closes if its system of

1:10.7

trigger hairs is tripped twice in 30 seconds.

1:13.4

The first signal starts the clock and the second signal,

1:16.7

if it comes, tells the jaws to snap.

1:19.4

Researchers have been trying to get to the bottom of this mechanism for a while,

1:23.3

but the plant wasn't ready to give up its secrets. The recent breakthrough came after a team
