What's the point of eyebrows?
|
Why do we have eyebrows? Can we taste food if we can't smell it? What's a cold sore? This week, we take on your science questions, as well as explore the world of social gaming, and find out how much it costs to fly an England flag from your car. We'll be asking if altitude affects how a football flies, if a large enough fan could propel a spacecraft and how spiders spin webs from one tree to the next. Plus, why size matters in bird beaks, how plant roots cope with competition and building lungs in the lab!

I know that the earth isn’t totally spherical. If mass stays the same but the gravity differs when moving from the midlatitudes towards the equator or polar region, how will it show for example when you take a Boeing 747 - how many percent can the measured weight differ compared...

In case you didn’t know, it’s the soccer World Cup in South Africa at the moment. The tournament’s being held in high altitude in some cases, so a couple of workmates told me that thin air could be affecting the movement of the ball through the air, but I'm sceptical. So what’s ...

Hi!
I enjoy listening to your podcasts, and now I have a question of my own I hope you might have an answer to. :) Recently I've been thinking about the Old Testament story of Jonah, who was swallowed by "a big fish" (or "a whale" according to the gospel of Matthew). Are ther...
If you take a rocket in deep space far from any planet, if you fire the rocket engine, would a rocket continuously accelerate tille burn out or would it end accelerating when its forward speed equals the speed the hot gases leave the nozzle of your rocket engine? thanks
