What is gravity without mass? Both Newton’s revolutionary laws describing its universal effect and Einstein’s proposal of a dimpled spacetime, we’ve thought of gravity as exclusively within the domain of matter. Now a wild new study suggesting that gravity can exist without mass, conveniently eliminating the need for one of the most elusive substances in

Batteries based on the wave-like nature of charged particles could revolutionize energy storage, potentially cramming in more power at a faster rate than conventional electrochemical cells could ever hope to manage. A new protocol developed by a team of physicists from National Cheng Kung University could transform the basic principles of a fast-charging quantum battery

For the first time, researchers have simulated neurological junctions called synapses using the same water and salt ingredients the brain uses, contributing to an emerging field that combines biology with electronics called iontronics. The team from Utrecht University in the Netherlands and Sogang University in South Korea claim to have been inspired by the functioning

Superconductivity continues to revolutionize technology in so many ways. While some technological advances rely on finding ways to encourage zero-resistance currents at warmer temperatures, engineers are also considering better ways of fine-controlling the super-efficient flow of electrons. Unfortunately, many processes that would work just fine for run-of-the-mill electronics, such as the application of external magnetic
