Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings ...

As summer kicks into full gear and people are spending more time outside, there's one thing on many people's minds—ticks.

Ogura can still remember that terrible morning in August, 80 years ago. Her older brother, who later died of cancer from ...

When the US warplane dropped a 4,400kg atomic bomb on Hiroshima, and 43 seconds later it detonated 600 metres above the city, ...

Theorists move quickly to explain discrepancyTwo protons and a neutron A discrepancy between two different measurements of the charge radius of the helium-3 nucleus may have been reconciled. (Courtesy ...

A research team has achieved a significant breakthrough in determining fundamental properties of atomic nuclei. The team conducted laser spectroscopy experiments on muonic helium-3. Muonic helium ...

For the first time, researchers from the PRISMA + Cluster of Excellence have determined the charge radius of helium-3 and thus also the exact difference to the radius of helium-4. This precision ...

The Atomic Spectroscopy Group provides standardized measurements used across wide swaths of science and industry. The Trump administration plans to cut it.

(4) Polydispersion of atomic radii or atomic size mismatch, δ (%), (radius and molar fraction dependent): it is the mean square deviation of the atomic radii involved (Equation 5) and directly ...

In this review, we provide an overview of how atomic force microscopy (AFM) measurements on wood or other plant fibers help us understand the structure–property relationship in growing plants, matured ...

We demonstrated the significance of considering confinement-induced changes in the electronic structure by comparing ionization radii computed for fixed electron configurations to those obtained in ...

Jane Richardson’s ribbon diagrams abstract proteins’ atomic structures into beautiful, clear illustrations. In this pencil drawing of triose phosphate isomerase, alpha helices and beta strands are ...
