Scientists have been working with atomic-scale memory tech that manipulates interaction between atoms so they could develop “a device that can pack hundreds of times more information per square inch than the best currently available data-storage technologies,” reports The Wall Street Journal. The prototype, described as a significant breakthrough, could be the next step toward storing future information — including photos, videos and posts from the Internet — more efficiently and affordably. Leading tech companies such as IBM and Hewlett-Packard are among those researching solutions to future data storage needs.
