'Stunning' discovery: Metals can heal themselves::Scientists for the first time have witnessed pieces of metal crack, then fuse back together without any human intervention, overturning fundamental scientific theories in the process. If the newly discovered phenomenon can be harnessed, it could usher in an engineering revolution—one in which self-healing engines, bridges and airplanes could reverse damage caused by wear and tear, making them safer and longer-lasting.

"Autonomous healing of fatigue cracks via cold welding"

That's the literal name of the paper. I'm quite over this story getting pumped around the internet. This is not news. This is not novel.

Also, this particular source leaving out the fact that the experiment was performed under vacuum is especially deceitful.

Sooooo... It's what we already knew then. Nice work, paper writers.
