Share Radio's tech whizz Steve Caplin tells Simon Rose why Amazon is closing 68 of its stores. For skiers going off-piste there's an autonomous ski lift on tracks or, more scarily, a portable tow rope with a winch. There's a car that can climb gradients greater than 50%, an infinity electric train at an Australian mine, we hear why planes are being covered with shark skin, about the company contracted to mine oxygen on the moon and a tide clock for surfers.

Political commentator Mike Indian looks at the political ramifications of the Russian invasion of Ukraine eight days in. With Ukrainian resistance greater than anticipated, he feels that – to paraphrase Churchill – this could be at least the end of the beginning for Vladimir Putin. The attack, argues Mike, is reinvigorating NATO but he feels more can be done to tackle Russian dirty money being sheltered in the UK while not indiscriminately targeting those hostile to Putin's actions.

Our commentary for w/c 28 February: as Peter Kropotkin predicted over 100 years ago, the communist legacy of centralised dictatorship has left the Russian leadership in a total moral vacuum, steered by fear and greed; and now, noting their nuclear warning, also with a degree of insanity. By a strange co-incidence, two programmes broadcast by the BBC on the day the war started point the way to a brighter future, if we can steer our path through the current tragedy engulfing Ukraine.

Russia's invasion of Ukraine has created a tragic situation that goes far beyond worries about our finances, but it will have an impact on them. The ins and outs of the conflict are not something that This is Money is qualified to comment on, but the financial impact of events is something that readers and listeners come to us to learn about. Georgie Frost, Tanya Jefferies and Simon Lambert look at what that impact could be. How the Russian-Ukraine conflict will affect out personal finances: from energy bills, to petrol prices and food, to the immediate volatility it has thrust on to people's investments, the team look at what is happening and what may happen next. Should investors stay calm and stick to their guns, or are their merits in one outlier suggestion of moving 50% to cash and battening down the hatches? Also, the added problem of inflation for people's investments and how to combat it. Plus, the latest on the state pension underpayment scandal and how some councils are now trying to rake in money from those paid back lump sums. And finally, its not an uncommon situation now to sell a property and step out of the market while you find a new one, but what should you do with a huge sum of cash in the meantime?

Rats induce fear and symbolise greed. Phobias are brought on by all sorts of things and people: this episode focuses on rodents. People apply a variety of coping strategies to deal with anxieties, and Adam Cox uses a technique called 'Staged Disassociation' to help provide a more effective approach to particularly challenging situations. Can there be a future without phobias? Please listen, and decide for yourself.

Victoria Scholar of Interactive Investor talks to Simon Rose about the startling market movements in the wake of the Russian invasion of Ukraine and why the FTSE is proving more resilient than some. With energy and safe havens in demand, how should investors react and position themselves, with the future so uncertain and events doing nothing to still recent volatility?

In the wake of the Russian invasion of Ukraine, Professor Tim Evans of Middlesex University speculates what Putin's aims might be and discusses how the West should react and, indeed, whether it will be able to manage without Russian oil, gas and even wheat. He explains about the coming refugee crisis for Europe and why China matters so much. He concludes with the ultimate question: How can we reboot the Western system to cope with what may prove a new era?

With Uncharted still riding high, James Cameron-Wilson reviews last weekend's UK box office. The only big new film is Channing Tatum's directorial debut, Dog, at #4 in which he also stars, oddly marketed as a family film. Resorting to streamed movies, James reviews box-ticking tornado disaster movie Thirteen Minutes with Thora Birch and Anne Heche and Texas Chainsaw Massacre, the 9th in the franchise, which he found a cut above the average modern horror, though not for the faint-hearted.
