Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to [email protected]. “What is radium and why is it dangerous?” – ...

Scientists have gained insights into the weak nuclear force from new, more sensitive studies of the beta decays of the 'mirror' nuclei lithium-8 and boron-8. The weak nuclear force drives the process ...

Students will test and observe how distance affects radiation measurements from radioactive sources. Students will test and observe how different types of shielding materials affect radiation ...

Why do some elements decay in minutes, while others last billions of years? Certain "magic numbers" of nuclear particles may make all the difference. When you purchase through links on our site, we ...

Neutrino mass measurements remain one of the most challenging endeavours in contemporary physics. Direct measurement techniques, particularly those probing the endpoint of the tritium β-decay spectrum ...

ASSERGI, Italy – In a research lab under almost a mile of rock and a six-centimeter-thick shield created from boiled-down lead from an ancient Roman shipwreck, physicists are observing a rare form of ...

Neutrinos are known for funny business. Now scientists have set a new limit on a quantum trait responsible for the subatomic particles’ quirkiness: uncertainty. The lightweight particles morph from ...
