Scientists have engineered single-molecule DNA computing controlled by stretching forces using magnetic tweezers. By tracking the real-time signals of the DNA extension, the output can be determined at a single base-pair resolution.
Researchers showed how high-resolution colour images could be printed on the non-allergenic pollen paper with a laser printer, and then 'unprinted' - by completely removing the toner without damaging the paper - with an alkaline solution.
Researchers show that honey can be used to make a memristor, a component similar to a transistor that can not only process but also store data in memory.
