Hi there, it's me. You got questions, I've got answers. Ask Tai Chi Chi, Chi Chi Timeline and Kristin. To play the message, press two. I kept my faith until I saw my cycles, how did I get them back? How did you get your freckles? That's a good one. So our skin has this stuff called melanin and basically freckles are just little dots of melanin. Melanin is this light absorbing pigment and helps us protect the skin from the sun's harmful UV rays by either reflecting or absorbing and just dealing with this radiation.

[00:00:53]

So when you have a tan, that's just the melanin acting up, doing its thing to protect you from the sun. Some people of more, some people have less. And that's just how the body works. People who are pale have less melanin, and that's why they tend to burn instead of tan. We have these skin cells called melanocytes, which is where melanin is made. Freckles happen when these melanocytes, they just got little hyperactive and create these really concentrated clusters of melanin like a tan, but just a single dot.

[00:01:24]

So you got them by being exposed to the sun at some point of your life and having particular melanocytes go a little overboard on the protection to go to the next message, press six.

Hi, my name is Henry. And why are video games so violent? Thank you. Why are video games so violent?

[00:01:53]

I mean, I think people just want to kind of try to do things that they wouldn't be able to do normally. So since, you know, I'm not really necessarily. Good to give an opinion, because I'm a little bit partial because I play video games myself. So with me, someone a little bit more impartial, Douglas Jones, Jill.

[00:02:23]

A lot of people believe that we have these urges that there, you know, they're there and we need to get them out. It turns out that's not actually true.

[00:02:35]

I'm Dr. Douglas Gentille and I'm a child psychologist and professor of psychology at Iowa State University, and I've been studying the effects of media on children, especially video games, since the 1990s.

[00:02:51]

If we think about what has helped humans survive across tens of thousands of years, part of it is being alert for danger.

[00:03:05]

And so whenever a fight breaks out in the school, the first thing everyone does is turn to look, and that's actually correct your first reaction, because if a fight breaks out, you might need to get involved with it. You might need to get away from it. But either way to figure that out, you have to look at it. And so violence makes us look. And so it keeps our attention. And, of course, a game designer wants you to stay involved in the game.

[00:03:36]

So violence is one way to kind of hook our attention. And this is why there's not only so much violence in video games, but also in television and movies. To go to the next message, press six, hi, my name is out, I'm calling from Halifax, Nova Scotia. And my question is, are changing the climate? Our hearts changing the climate. Well. Well, that's very interesting because our farts, I'd say that our farts or they're pretty good, you know, we've done pretty good keeping them limited.

[00:04:19]

Sometimes we eat too many beans, but I think we're keeping it under control. I read this thing. The big thing is that it's not our farts, it's cow farts. I don't know too much more than that, so I'm going to give this over to our CBC meteorologist and science reporter, Joanna Wagstaff. Joanna, take so away on the FART'S.

[00:04:43]

The short answer is yes. Farts are actually changing the climate.

[00:04:51]

Mammals have always been farting and burping and releasing methane, but it's really cows that are the big game changers when it comes to global warming.

[00:05:03]

Right now, there are so many cows around the world are, you know, over one billion cows, all farting and burping. This methane gas and methane is a greenhouse gas. You've probably heard of CO2 or carbon dioxide as being a greenhouse gas, which basically acts as a big blanket around Earth that warms our planet up. And methane is an even bigger greenhouse gas than CO2. We don't have as much of it in the in the atmosphere. But NASA estimates since the turn of the century, methane gas emissions have increased by 150 percent.

[00:05:36]

And that's because we're using cows in different ways. We're concentrating them in areas for beef and for milk. And it's the sheer number of them concentrated in one area that's leading to this massive increase in methane. Actually, it's not just the cow farts that contribute to the release of methane. Cow burps actually have more methane in it. So when cows are digesting through their four different stomachs and the byproduct is methane, a lot of it gets burped out at the beginning rather than at the end.

[00:06:07]

But both of the burps and the farts are contributing to the warming that we're seeing around the planet right now.
