    Is rainwater safe to drink?

    On Earth, water gets evaporated by the sun from the planet’s surface, and then drops back down from the clouds when it rains. That’s a great source of water, but..is that water safe to drink?  We asked environmental researcher Dr Jonathan Sexton to help us find the answer. Got a question in your bRAIN? Send it to us at BrainsOn.org/contact, and we’ll help filter out the answer.

    How do stars form black holes?

    Black holes are areas in outer space that have gravity so strong that not even light can escape its pull! Some black holes are formed from stars…so how does a star go from a burning ball of gas to a light-swallowing void?  We asked UCLA astrophysicist Dakotah Tyler to help us find the answer. Got a question that’s really pulled you in? Send it to us at BrainsOn.org/contact, and we’ll help you gravitate towards the answer.

    How do batteries work?

    Batteries power lots of stuff that people use everyday, like cellphones, toys and laptop computers. Some batteries can even be recharged after they run out of juice.

Send it to us at BrainsOn.org/contact, and we’ll run a whole battery of tests to find the answer.

    Why do we rub our eyes when we're tired?

    It seems universal that when a person - old or young - is tired, they rub their eyes. It’s even a way that babies communicate to their adults that they are ready for bed. Are we just born understanding that signal? Or is there something going on with our eyes that they need to be rubbed when we’re sleepy? Otolaryngologist Dr. Laura Orvidas helps us understand the connection in this episode. And stay tuned for the week of May 30, when all of our episodes will be sleep-themed. It’ll be a real “snooze fest”! Got a question you’ve been eyeing? Send it to us at BrainsOn.org/contact, and we won’t sleep on the answer!
