He needed sunshine for his test. Paris gave him a week of gray skies. What he found in the drawer changed physics. The post ...

Cryoconite, a dark sediment that is a mixture of fine inorganic and organic matter, is found in shallow holes in the surfaces of glaciers. In Norway, surprisingly large amounts of artificial ...

This comprehensive Radioactivity and Nuclear Physics bundle supports clear, progressive teaching of atomic models, subatomic particles, isotopes, radioactive decay, nuclear equations, activity, ...

For the first time, researchers have developed a way to create chilled molecules containing the radioactive element radium. The resulting laboratory concoctions, generated in part through steps ...

Using lasers with precisely tuned frequency, λ, physicists control rotational states of radium monofluoride molecules and excite specific rotational levels, characterized by the quantum number, J.

A tabletop method for producing cold radioactive molecules enables precise measurement of their properties and could uncover violations of fundamental symmetries. Radium has a pear-shaped nucleus that ...

A concentration of one part per billion is like a pinch of salt in 10 tons of potato chips—and scientists can now find radioactive particles at concentrations millions of times smaller. In the Journal ...
