As Russia continues its invasion of Ukraine, gas prices remain high around the world. Europe is dependent on Russia for about 40% of its natural gas supplies, and despite the expansion of renewable energy over the past two decades, that dependency is increasing as countries shift to gas from dirtier coal. Putin’s attack on Ukraine has put this reliance into sharp focus as Europe considers how to respond. Madeleine Finlay speaks to our environment correspondent Fiona Harvey about how Putin has weaponised Russia’s fossil fuels, and how Europe could reshape its energy supplies for the future.

Ian Sample speaks to the theoretical physicist Sean Carroll about his mission to demystify quantum mechanics. It won’t be easy, though, as Carroll’s favoured interpretation of this fundamental theory – the ‘many worlds’ interpretation – results in a possibly infinite number of parallel universes.

Despite being something that will affect half the world’s population, the menopause, and how it can lead to things like hot flushes, has historically been a bit of a ‘black box’ for scientists. But thanks to new insights from animal research, a much-needed alternative to hormone replacement therapy could be just around the corner. Hannah Devlin investigates.
