This animation displays a scan of arrow-shaped flakes of a 2D material. Samples were scanned across their electron energy, momentum, and horizontal and vertical coordinates using an X-ray-based technique known as nanoARPES at Berkeley Lab’s Advanced Light Source. Red represents the highest intensity measured, followed by orange, yellow, green, blue, and purple (least intense). (Credit:... Read more

This instrumentation at Japan’s Radioactive Isotope Beam Factory in Wako, Japan, was used in an experiment to create an exotic magnesium isotope. (Credit: Heather Crawford/Berkeley Lab) ) Just over a decade ago scientists pushed magnesium atoms to new limits, jamming extra neutrons into their nuclei toward – and possibly reaching – the maximum limit for this element. Now, an... Read more

A century ago, the periodic table looked much different than it does today. It had empty spots for elements that had not yet been found, and ended at uranium (element 92), the heaviest known element until 1940. But scientists were dreaming about artificially creating even heavier elements.“For some reason, they thought you could go beyond uranium,” said Berkeley Lab scientist Gauthier... Read more
