All around the world, scientists are trying to beat the most debilitating condition known to humans: ageing. Here is how worms and 3D printers can help.

What exactly is ageing? If you could zoom into the molecular level, you would see small, incremental amounts of damage that spreads to the cells, the tissue and the organs. Eventually, the whole organism starts to suffer from this ongoing Russian-doll style accumulation of damage.

“Then when we can’t keep up with the repairing, the ageing starts” explains Danish physician Kaare Christensen.

Christensen worked as a doctor for many years until one day he decided he’d had enough of treating sick people. He now runs the Danish Aging Research Centre where he’s trying to stop people getting ill in the first place. 

He points out that we’ve seen some progress. In the mid-1800s life expectancy was around 40 years in most of the world, he says, while now some countries of Northern Europe are nearing 80 years and the rest of the planet is catching up.
