Stone, parchment or laser-written glass? Scientists find new way to preserve data
Hard disks and magnetic tape have a limited lifespan, but glass storage developed by Microsoft could last millennia
Some cultures used stone, others used parchment. Some even, for a time, used floppy disks. Now scientists have come up with a new way to keep archived data safe that, they say, could endure for millennia: laser-writing in glass.
From personal photos that are kept for a lifetime to business documents, medical information, data for scientific research, national records and heritage data, there is no shortage of information that needs to be preserved for very long periods of time.

Thanks to the rise in real estate technologies, renters often have no choice but to hand over huge amounts of revealing information to digital third parties just to have somewhere to live. All the while we are told: trust us, we take your privacy seriously.
But recent Guardian reporting has revealed that seven popular βrent-techβ platforms have serious security vulnerabilities, leaving millions of documents containing personal information of renters exposed on the open web for years. When they were alerted to the risk, only two of the seven companies responded to say they would put additional security measures in place. Is this what taking renter privacy seriously looks like?
