Segment 7A: Radioactive Decay We explore the nature of radioactivity. Segment 7A: Radioactive Decay We explore the nature of radioactivity and describes the types of radioactive decay that occur.

Why do some elements decay in minutes, while others last billions of years? Certain "magic numbers" of nuclear particles may ...

In a new set of results, chemists have laid the foundation for a single-atom illumination strategy called barium tagging. Their achievement is the first known imaging of single atoms in a solid noble ...

At any given moment, trillions of particles called neutrinos are streaming through our bodies and every material in our ...

Alpha recoil: Conceptual drawing of the experiment, which detects the nuclear decay of individual helium nuclei by embedding radioactive atoms in a micron-sized object and measuring the object’s ...

Anomalies in the radioactive decay of beryllium-8 and helium-4 point to the existence of a new force of nature. That is the conclusion of a group of theorists in the US, who have scrutinized data from ...

The Standard Model of physics, which explains the properties and interactions of the fundamental particles, does a phenomenal job with the things it gets right, and there's nothing that it obviously ...

In the icy bodies around our solar system, radiation emitted from rocky cores could break up water molecules and support hydrogen-eating microbes. To address this cosmic possibility, a team modeled a ...

Scientists poke and prod at the fringes of habitability in pursuit of life’s limits. To that end, they have tunneled kilometers below Earth’s surface, drilling outward from the bottom of mine shafts ...

A team of Italian researchers has uncovered compelling evidence of anomalous radioactive decay in cobalt-57 (Co-57) under ultrasonic stimulation, offering strong experimental support for the Deformed ...

The subatomic particles called neutrinos are famously elusive. But an unconventional trick could make a laser beam of the aloof particles.
