Size of helium nucleus measured more precisely than ever before

In experiments at the Paul Scherrer Institute PSI, an international research collaboration has measured the radius of the atomic nucleus of helium five times more precisely than ever before. With the aid of the new value, ...

A new way to measure record-setting electron beams

Physicists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) are figuring out new ways to accelerate electrons to record-high energies over record-short distances with a technique that ...

Metamaterial tiles boost sensitivity of large telescopes

A multi-institutional group of researchers has developed new metamaterial tiles that will help improve the sensitivity of telescopes being built at the preeminent Simons Observatory in Chile. The tiles have been incorporated ...

A benchmark for single-electron circuits

Manipulating individual electrons with the goal of employing quantum effects offers new possibilities and greater precision in electronics. However, these single-electron circuits are governed by the laws of quantum mechanics, ...

Discovery makes the invisible visible

Australian scientists have discovered a new way to analyze microscopic cells, tissues and other transparent specimens, through the improvement of an almost 100-year-old imaging technique.

Nuclear physicist's voyage toward a mythical island

Theories were introduced as far back as the 1960s about the possible existence of superheavy elements. Their most long-lived nuclei could give rise to a so-called "island of stability" far beyond the element uranium. However, ...

To find the right network model, compare all possible histories

Two family members test positive for COVID-19—how do we know who infected whom? In a perfect world, network science could provide a probable answer to such questions. It could also tell archeologists how a shard of Greek ...

Physicists discover new physical effect

Scientists have found that a perpendicular magnetic field makes electrically neutral quasiparticles (excitons) in semiconductors behave like electrons in the Hall effect. This discovery will help researchers to study the ...
