“With the [atomic] bomb we dropped in Nagasaki, it killed everybody within a mile radius,” Morse told TIME on Friday, adding that a hydrogen bomb’s reach would be closer to 5 or 10 miles.

Next month it will have been 80 years since the Japanese cities of Hiroshima and Nagasaki were devastated by nuclear attacks.

1.97007 femtometer (quadrillionths of a meter): That's how unimaginably tiny the radius of the atomic nucleus of helium-3 is. This is the result of an experiment at PSI that has now been published ...

The “proton radius puzzle” has been reinforced by a precise measurement of an atomic transition in muonic deuterium, which suggests the radius of the deuterium nucleus is much smaller than expected.

Scientists, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen. Scientists from the Max Planck ...

Seven years after the end of WWII, the US detonated the world's first hydrogen bomb. H-bombs use a combination of nuclear fission and fusion and are far more powerful than atomic bombs. Edward ...

Hydrogen bombs are thousands of times more powerful than their atomic predecessors. The first hydrogen bomb the United States ever tested in the Marshall Islands in 1952, called Ivy Mike, had the ...

A new map of the Milky Way’s atomic hydrogen, anchored by precise distances to young Cepheid stars, reveals the galaxy’s gas disk is highly clumped and flocculent rather than smooth.

The Hydrogen-Atomic partnership yields numerous value propositions for Hydrogen and its clients. Gig economy companies can leverage Hydrogen’s Atomic widget to empower their 1099 workers access ...

Scientists at EPFL and AstraZeneca have developed a method to map the atomic-level structure of amorphous drugs, demonstrated on a GLP-1 receptor agonist candidate for diabetes and obesity treatment.

The charge radius is a statistical measure of how far the electric charge of a particle extends into space. Both groups were ...

The proton, discovered 100 years ago 1, is an essential building block of visible matter. The nucleus of a hydrogen atom consists of a single proton, making this atom a suitable platform for ...
