5D 'Superman Memory' Crystal — Unlimited Lifetime Data Storage
University of Southampton researchers demonstrated 5D optical data storage in quartz glass using femtosecond laser writing — 360 TB per disc, theoretically stable for billions of years. An early result from the lab that eventually led to Project Silica.
It Takes 275 Water Molecules to Make Ice
Scientific American podcast item: researchers determined that a cluster of exactly 275 water molecules is the minimum required to form an ice-like crystalline structure — a finding that probes the boundary between bulk and nanoscale physics in water.
Sodium-Ion Battery Electrode Breakthrough
Researchers developed a new metal-oxide electrode material enabling sodium-ion batteries that could substitute for lithium-ion in stationary energy storage. Sodium is 1000x more abundant than lithium and much cheaper, making this a scalable alternative for grid storage.
