In the days since Vladimir Putin ripped up the international playbook and invaded Ukraine, western leaders have been issuing sanctions with a zeal not seen in many years. Much of this has revolved around cutting Russia and its institutions out of the Swift international payments system, and you would be forgiven for thinking that this is why the rouble has crashed and Russia’s central bank has more than doubled interest rates.

In fact, says finance professor and Swift advisor Alistair Milne, what Swift is for and the extent to which it can be used as a weapon is widely misunderstood. While western sanctions have impacted Russia’s economy, the damage done has little or nothing to do with Swift.

Elsewhere, we report on an institute at Oxford University that is building a genetic family tree of everyone that has ever lived. We also look at how, in future, we will be able to 3D-print cities – using concrete made from recycled glass.

Swift: ejecting Russia is largely symbolic – here’s why

Most media coverage has tended to focus on the Swift payments messaging system as the crux of Russia sanctions, but it’s actually peripheral.

Glass is produced from sand, is easy to recycle, and can be used to make concrete without any complex processing.
