Hey there, curious minds. I'm Dr. Samantha Amin, also known as Science Sam, but my friends just

call me Sam, and I'm here to tell you all about the new season of Curiosity Weekly from Discovery.

We're mixing things up a bit. We're going to talk about the latest and greatest in scientific research,

I've been obsessed with science from a very young age. Science is more about questions and

That's Dr. Anastasia Boyoskaya, a behavioral scientist. Later, we'll talk with her about her

research on habit formation and debunk

the 21 days myth, because who doesn't want the secret to actually sticking to their New Year's

resolution? And then, for all you self-paws out there, we'll cover a newly discovered link

between musical training and left-handedness.

Bacteria are living on the International Space Station, and not only are they surviving,

but they are thriving.

January 15, 1998, NASA astronaut Dave Wolf is on board, Russia's mere space station.

They need to know if microorganisms pose a threat to the astronauts.

When the crew opens a rarely used service panel, they find a huge globule essentially of water that's just teeming with organisms.
