How would you measure time when in space?

This week we've been against the clock to get the answer to this question from David "What measurement of time would you use in travelling through space as a day, week, month or a year would become meaningless, and how would this affect the body clock?" Eva Higginbotham spoke to space sleep expert Cassie Hilditch, and also former NASA astronaut Steve Swanson, to find out the answer... Like this podcast?

Why do I need to pee more nearer the loo?

This week we're flushing out the answer to this question from Charlie: "Maybe this is just me, but it dawned on me that whenever I have to hold in a pee, the need to go increases exponentially when I know that relief is close. Why is this?" So to relieve Charlie of his question, I asked physiologist Bill Colledge from Cambridge University to expel the answer... Like this podcast?

Why do particles gather in a bucket's centre?

Six-year-old listener Jonathan asks: "when you stir a bucket of water, I know the water is pushed to the outside; however, why do any particles end up the centre after the water has finished spinning? I have asked my Dad, but he doesn't know." Phil Sansom found someone who does know - and it's fluid dynamics expert Dan Nickstroem... Like this podcast?

Do our brains process sound or light faster?

Lionel got in touch to ask us about a curious phenomenon he's noticed since installing a new sensor, raising the question whether our brains process light or sound faster.

Should you wash, rinse, and repeat?

Julie got in touch to ask whether there was any reason to wash, rinse and repeat, or if it was just marketing hype. Phil Sansom spoke to two hair specialists, Sally-Ann Tarver and Eva Proudman, about this hairy issue... Like this podcast? Please help us by supporting the Naked Scientists

Why do hospitals need so much PPE?

Carol got in touch to ask "The government has provided more than a billion items of PPE to hospitals. There have been 130,000 COVID cases in hospitals, about 10,000 items of PPE per patient. Can you find out why so much?" Eva Higginbotham put the question to medic Isabelle Cochrane... Like this podcast? Please help us by supporting the Naked Scientists

How alike are the kids of identical twins?

Sam got in touch to ask: "If identical twin brothers marry identical twin sisters, and each of those couples has a child, will those two children be like twins?"

Why aren't planes dimpled like golf balls?

Darren got in touch to ask us: "Golf balls are dimpled to disrupt the air around the ball. As far as I can gather, this reduces their drag and allows them to fly further than they would if they were perfectly round. Why do we not see dimpled cars, aircraft, and trains? If this effect is so effective for golf balls, why not use it on Formula 1 cars, for instance?"Adam Murphy went looking for a hole-in-one to this question, and spoke to Sam Grimshaw from the Whittle Lab at the University of Cambridge...
