Amplified spontaneous emission is a physical phenomenon that entails the amplification of the light spontaneously emitted by ...

So, what is supplying enough energy to knock the negatively charged electrons out ... The researchers think that these tiny ...

When researchers at the Los Alamos National Laboratory visualized data from the first few nanoseconds of a lightning, they ...

A strange energy source at the center of the Milky Way may be a new type of dark matter. Scientists found that hydrogen gas ...

NASA’s Perseverance rover recorded unusual sounds as a Martian dust devil passed directly over the robotic vehicle in 2021, ...

A new study suggests that clues about dark matter may be hidden in the Milky Way's Central Molecular Zone, where unexplained ...

Scientists suspect lightweight dark matter might ionize hydrogen in the Milky Way’s core. This could also explain the 511-keV ...

The top, phosphorus-doped layer contains more electrons, or negatively charged particles, than pure silicon does, while the bottom, boron-doped layer contains fewer electrons. This difference is ...

An international team of researchers has discovered a new method to generate electricity using small plastic beads. By ...

Tell students that each salt crystal is made up of two different types of particles called sodium ions and chloride ions. Tell students that ions are atoms or molecules that have either a positive or ...

The work could be a step toward understanding the effects behind the phenomenon of static electricity, in which electric charge accumulates on materials after they are rubbed or touched together.

This resulted in the particles' negative surface charge being neutralized, enabling them to diffuse readily in mucus gel at a rate just ten times slower than in water, an unhindered medium.
