The first weekend of the Italian summer will be hot and sunny everywhere but sudden thunderstorms will hit certain areas, ...

Theories must stand up to practical testing, and this is especially true in physics. Researchers from Johannes Gutenberg ...

Nuclear fission involves splitting a heavy atomic nucleus into smaller nuclei and releasing a significant amount of energy. This process typically occurs when a neutron collides with an unstable ...

In the second type, the unstable nucleus emits a positron (a positively charged electron, also called an antielectron) and a neutrino while converting a proton to a neutron. Positrons and electrons ...

Radioisotopes are atoms that have an unstable nucleus, and so shed excess energy as radiation in a process called radioactive decay. These active chemical species have numerous applications across ...

Imagine a cell phone with a battery that lasts for years and doesn’t need to be plugged in to recharge. Or a drone capable of flying indefinitely over Amazonia, registering deforestation and illegal ...

Radioactive decay is ubiquitous. It occurs everywhere on Earth and throughout the universe. The most common forms occur when an unstable nucleus spits out an alpha particle, consisting of two neutrons ...

For example, in a nuclear process called β decay, an unstable nucleus converts a neutron to a proton, and in doing so emits an electron and an electron antineutrino.

An atomic nucleus with a weight of 260 or more falls into a realm of elements beyond 100: elements found only in the lab. And even in the lab, they’re far too unstable and short-lived for ...
