It's one thing to dream up a quantum internet that could send hacker-proof information around the world via photons superimposed in different quantum states. It's quite another to physically show it's possible. That's exactly what physicists have done, using existing Boston-area telecommunication fiber, in a demonstration of the world's longest fiber distance between two quantum memory nodes to date.

Scientists have made a significant advance in laser plasma acceleration. By employing an innovative method, a research team managed to substantially exceed the previous record for proton acceleration. For the first time, they achieved energies that so far have only seemed possible at much larger facilities. As the research group reported, promising applications in medicine and materials science have now become much likelier.

Researchers have used a novel combination of short-read and long-read RNA sequencing to identify the different isoforms of genes expressed in the crustacean Daphnia magna. Males and females are genetically identical, but using this technique the team revealed genes that switch the predominant isoform in a male-female-dependent manner. This study may help further advance technologies in crustacean aquaculture.
