Neutrinos are low-mass subatomic particles with zero electric charge that interact with matter only via the weak nuclear force and gravity. This makes neutrinos difficult to detect, despite the fact ...

What these two processes share is baked into the math of each. In fact, in that respect, they're nearly identical. They both involve some stuff (atoms or money) that is either growing or shrinking.

In this lesson, students will simulate the randomness of decay in radioactive atoms and visualize the half-life of a sample radioactive element. This lesson can be completed in two (2) 45-minute class ...

Think about a garden where flowers bloom beside nuclear reactors. It sounds impossible, yet it's happening right now. Since the Chernobyl disaster in 1986, scientists have watched in amazement as ...

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 ...

Cause and Effect: Understanding the causes of radioactive decay and its effects on materials and organisms. (Example: Exploring how distance and shielding materials affect exposure to radiation.) ...

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 ...

Analysis of meteorite Erg Chech 002 shows that the radioactive isotope aluminum-26 was unevenly distributed in the early Solar System, overturning previous theories. (Yuri Amelin) A little over four ...
