DNA-based molecular tagging system could replace printed barcodes

Science
Nov. 3 (UPI) -- A new DNA-based molecular tagging system could change the way goods, from vaccines to textbooks, are tracked. The trackable plastic tags commonly found on clothes do more than prevent retail theft. Advertisement Radio frequency identification -- and other tracking technologies like barcodes and QR codes -- helps manufacturers, logistics operators, transportation coordinators and warehouse managers keep tabs on inventory.

Judge stops 3D printed gun plans publication

Technology
A judge has blocked the publication of blueprints for parts of a gun that can be made by a 3D printer and, it is claimed, would be undetectable. The Trump administration had previously given the go-ahead for the online publication of the plans, which show how to make a firearm from printable parts.The gun's components can be made with a printer that uses plastic instead of ink. Layers of plastic are built up until they make three-dimensional plastic pieces.The company behind the plans, Defense Distributed, reached an agreement with the federal government in June allowing it to make the plans for the guns available for download, starting this week.
