The most distant object ever discovered as well as the events of National Pathology week feature in this week's show as we take on your science questions! We investigate why socks go missing in the wash, if light from the Sun is a continuous beam and whether numerous vaccines can be given together in one dose. We also find out how higher heels make for a better runner and reveal the world's fastest camera. Plus, we find out why holding an aerial gives a better TV picture and show you how to make a helicopter using card and pencils!

Chris Smith finds out about the most distant object ever discovered and how this has improved our understanding of our universe...
Why don't electrons stick to protons if there’s electrons whizzing around the outside of an atom and the protons are the positive bit in the middle? Why don't the two just collapse in on each other?
Why do car wheels appear to move backwards when you view them under streetlights sometimes?
It has been discussed on your show about genes being turned on and off through things like genetic engineering and I’ve got a picture in my mind a sort of a big double helix with old-fashioned light switches sticking out the sides of it, which I seriously doubt is correct. And I...
I've always been taught, an early age, that if meat has been frozen and thawed, you shouldn’t re-freeze it because of food poisoning. But why is this?
In an article I read this week, they said that the coldest spot in our solar system was a crater on the south pole of the moon. The temperature’s about - 238 degrees. I realise this is close to absolute zero. But if absolute zero is the coldest temperature we can achieve, is t...
Can vaccines can be given together? I know someone that just received four vaccines at once. Can they wear out the immune system and not produce as good a response?
Is the Earth getting heavier owing to plant photosynthesis converting energy into mass. And if so, does this affect the Earth’s spin?
If I have a torch and I put three batteries in it and two are fully charged and one is fully drained, will the torch still produce light?
Does a supernova, in other words, the death of a star clear out a planetary system completely of everything that used to orbit the star?
We find out about the life of a pathologist and what events we have to look forward to as part of National Pathology Week...
Why is it that the sun warms us up on Earth while it remains cold above us despite the fact that above us is really closer to the sun and at some point closer to the sun it’s probably really hot so at what point does it become freezing cold?
Why are valleys colder than areas that are higher up?
Why can you see the moon during the day?
Why do magnets have healing properties? - If they do, that is...
Does water weigh less when it’s boiled? My kettle feels lighter when water is boiled than when it’s cold.
Light from the stars travels millions of miles away but this is a continuous beam? Also, if you’re in, for example, Australia would you see the same light as somebody who’s in the UK?
Build your own helicopter using just a piece of card, some tape, and a few pencils.
I would like to know where socks go when they put some into the washing machine? I made some observation that I put matching socks into the washing machine and I get only single socks back. Yes socks are not quantum mechanical entities. Where are the socks going?
Why does television signal improve when you hold the aerial?
