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.

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 ...

Can physics predict the future? This video explores the concept of predictability in the universe, starting with the ...

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 ...

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 ...

Researchers refute the assumption that the decay rate of some radioactive nuclides depends on the distance between the Earth and the Sun. PTB researchers refute the assumption that the decay rate of ...

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 ...

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 ...

We recently reported on a theory that says our universe might not have gotten its start when it collapsed in on itself and exploded. The theory says that such an event may have been prevented by the ...

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 ...
