Teens and antidepressants, stamp duty savings and earthquake probabilities
A survey from a mental health charity suggested that more than a third of British teenagers had been prescribed antidepressants. We debunk the figure. Also we investigate a tweet from the UK Treasury about how much homebuyers will save in stamp duty. Plus how Mexico has been hit by earthquakes three times on the same day of the year - what are the chances? And how incorrect figures from the government have given a false picture of the number of cars on Britain’s minor roads. Presenter: Tim Harford

NASA’s asteroid collision: how many asteroids are really out there?
This week NASA slammed a spacecraft into an asteroid in the hope of diverting its course. The Double Asteroid Redirection Test or DART mission will help scientists understand how easy it would be protect Earth if one was headed in our direction. More Or Less first discussed this in 2016 with a little help from the movie Armageddon – with listeners getting in touch once again we ask how many asteroids are really out there and how dangerous they might be to Earth.

Falling pound, the Queen’s funeral and is 0.5 on the Richter scale a big number?
The value of the pound against other currencies has been incredibly volatile ever since the Chancellor’s ‘mini-budget’. We ask how much we should worry and look at how much taxes will really fall. Also did 4.1 billion people really watch the Queen’s funeral? Gas prices are falling – so why aren’t energy bills? There are early signs that new covid variants could cause another spike in cases over the winter. And with the government lifting a moratorium on fracking, we ask how seismic a number the current limit of 0.5 on the Richter scale actually is.Presenter: Tim Harford

Ukraine has reportedly recaptured nearly 10,000 square kilometres of territory that had been occupied by Russia. We ask where the numbers come from and what they mean.

Ukraine offensive, weak pound & how much do women really exercise
Ukraine has reportedly recaptured nearly 10,000 square kilometres of territory that had been occupied by Russia. We ask where the numbers come from, what they mean and why everyone is comparing them to the size of Greater London. We ask how much money Norway is making out of the current energy crisis. Also why is the pound so weak against the dollar, some odd claims about women and exercise and does it really take 20,000 uses for an organic cotton bag to become more environmentally friendly than a plastic bag?Presenter: Tim Harford

Energy crisis plan, imperial measures survey, gardens v national parks
One of Liz Truss's first acts as Prime Minister was to announce a giant plan to protect domestic energy users from huge rises in wholesale gas and electricity costs, meaning a typical household will pay about £1000 less than otherwise would have been the case. We ask how much the Energy Price Guarantee will cost the government and also explain what a “typical” household really is. A consultation has opened into whether we’d like more of our goods and services priced in imperial measures – but some listeners are suggesting a survey on the issue is biased against metric. And we examine a claim made on the BBC’s Springwatch programme that all of the gardens in Newcastle are bigger than the combined size of our national parks.Presenter: Tim Harford
