Condition when flames are moved (left), Diagram of state (right). Credit: Toyohashi University of Technology. A research team, led by Professor Yuji Nakamura of the Department of Mechanical Engineering at Toyohashi University of Technology, discovered that the flickering of flames can be freely controlled by moving two flames closer together or further apart. Until now,…

Exploring the Borders of the Nuclear Landscape
March 31, 2023• Physics 16, s40 Scientists have precisely measured the masses of 19 neutron-rich nuclei, discovering a new isotope of uranium in the process. APS/Carin Cain APS/Carin Cain × The properties of heavy, neutron-rich isotopes are poorly known owing to difficulties in synthesizing these nuclei. Now Toshitaka Niwase at the High Energy Accelerator Research…

Behind the Cover: April 2023
Each month, Physics Today editors explore the research and design choices that inspired the latest cover of the magazine. The April issue of Physics Today has two stories about research in Antarctica. One is about using instruments that swim beneath Thwaites Glacier to study its melting. The other concerns the search for Earth’s oldest ice, conducted…

A Tale of Differing Mass and Size Measurements
The proton mass radius is smaller than the electric charge radius (a dense core), while a cloud of scalar gluon activity extends beyond the charge radius. This finding could shed light on confinement and the mass distribution in the proton.
