Optical data storage has virtually unlimited lifetime

(Phys.org) —Data stored on today's CDs and DVDs has a lifetime of several decades before the physical material begins to significantly decay. Researchers are working on prolonging the lifetime of stored data, but so far ...

Examining a nanocrystal that shines on and off indefinitely

In 2021, lanthanide-doped nanoparticles made waves—or rather, an avalanche—when Changwan Lee, then a Ph.D. student in Jim Schuck's lab at Columbia Engineering, set off an extreme light-producing chain reaction from ultrasmall ...

Researchers achieve record entanglement of quantum memories

A network in which data transmission is perfectly secure against hacking? If physicists have their way, this will become reality one day with the help of the quantum mechanical phenomenon known as entanglement. For entangled ...

Astronomy team finds evidence of galactic metal shrouded in dust

A thorough understanding of galaxy evolution depends in part on an accurate measurement of the abundance of metals in the intergalactic medium—the space between stars—but dust can impede observations in optical wavelengths. ...
