- Hologram technology: the sub-atomic future of storage?
- I was recently talking to some folks at Google about storage, specifically the amount of data that's being stored on the cloud as users upload things like photos and YouTube video clips. Gigabytes. Terabytes. Petabytes. I couldn't help but wonder, as we talked about all of this...

- Quantum holographic storage: it works!
- Researchers at Stanford University have demonstrated quantum holographic storage, shattering long-held assumptions about the information limits of matter. Moving into the sub-atomic realm, they permanently stored 35 bits in the quantum space surrounding a single electron. Moreover, the technique allows holograms to be "stacked" in 3 dimensions....

- 3-D images of a virus at half-nanometer resolution
- U.S. researchers have used a new technique named cryo-EM (short for 'Electron cryomicroscopy) to capture images of a virus at a resolution of 4.5 angstroms -- less than half of a nanometer. As said the lead researcher, 'This is the highest resolution ever achieved for a living organism of this...

- What is nanopantography?
- If you don't know the answer, I cannot blame you. After all, a query for 'nanopantography' on Google returns only 43 results as I'm typing this. But researchers from the University of Houston say that nanopantography can create billions of nanotech devices in hours. The idea behind the technology is...
