Sustainable forestry: If you go down to the woods today

IN FINLAND’S vast forest lives a monster with a voracious appetite. Once, it would have been called a pulp mill. But after a recent makeover costing €1.2bn ($1.3bn) it is now known as a bioproducts mill—and as such is one of the biggest in the world. This sprawling plant, near Äänekoski, a town in the […]

Flying taxis are taking off to whisk people around cities

In october 1908, on a windy field at Farnborough, south-west of London, a handlebar-mustachioed former Wild West showman named Samuel Cody completed the first official controlled flight of a powered aeroplane in Britain.

Inside the body shop: 3D printing replacement body parts

A robotic lawnmower keeping the grass neat and tidy outside a modern industrial building in Carrigtwohill, near Cork in Ireland, is a good indication that something whizzy may be going on inside. And so it proves. The airy production hall contains row after row of 3d printers, each the size of a large fridge-freezer. The machines […]
