Billion-year ultra-dense memory chip developed

There's always been an inverse relationship between density and durability when it comes to data storage. Today's silicon memory chips contain a lot of density, but with a lifespan of just a few decades, they lack durability.  Yet primitive forms of storage such as information carved in stone are highly...

Self-healing ceramics for nuclear safety

Pacific Northwest National Laboratory PNNL researchers have used supercomputers to simulate how common ceramics could repair themselves after radiation-induced damages. This is an important discovery because 'materials that can resist radiation damage are needed to expand the use of nuclear energy.' These ceramics, which are able to handle high-radiation doses,...
