Increasing amounts of data require storage, often for long periods. Synthetic polymers are an alternative to conventional storage media because they maintain stored information while using less space and energy. However, data retrieval by mass spectrometry limits the length and thus the storage capacity of individual polymer chains.
Researchers have now introduced a method that overcomes this limitation and allows direct access to specific bits without reading the entire chain.
Data accumulates constantly, resulting from business transactions, process monitoring, quality assurance, or tracking product batches. Archiving this data for decades requires much space and energy. For long-term archival of large amounts of data that requires infrequent access, macromolecules with a defined sequence, like DNA and synthetic polymers, are an attractive alternative.
Kyoung Taek Kim and his team at the Department of Chemistry at Seoul National University have developed a new method by which very long synthetic polymer chains whose molecular weights greatly exceed the analytical limits of MS and MScan be efficiently decoded. As a demonstration, the team encoded their university address into ASCII and translated this -- together with an error detection code -- into a binary code, a sequence of ones and zeroes.
As the world's data storage needs grow, new strategies for preserving information over long periods with reduced energy consumption are needed. Now, researchers have developed a data storage approach ...

Plants have a backup plan | ScienceDailyPlants like Arabidopsis rely on a molecule called DDM1 to pass down accurate chromosome copies to future generations. But if it's so important, why isn't Arabidopsis affected when DDM1 is lost? After 30 years, botanists have found the answer. Arabidopsis has a backup plan known as RNAi.
