Understanding instabilities and turbulence in plasmas is one of the key challenges across a wide range of plasma research fields, including nuclear fusion, astrophysics and laser-plasma physics. In…
The positron is the antimatter counterpart of the electron, identical in mass but carrying an equal and opposite electric charge. Like the electron, it also behaves like a tiny bar magnet, and…
Every time a bubble rises through water, or oil separates from ocean sediment, or steam escapes from boiling water, something remarkable is happening at a fundamental physical level. The interplay between gravity, pressure, and the invisible forces that govern the movement of two different phases—whether liquid and gas, or two immiscible liquids—reveals one of nature’s … Read more

Researchers at AIST have directly observed magnetic flux quanta generated in a superconductor by photon absorption and demonstrated a new principle of photon detection that identifies the number of…
In 1953, two physicists showed that an electron beam skimming past a grating emits light whose color depends only on the electron’s speed and the grating’s spacing. Known as Smith-Purcell radiation,…
Glass can keep a drink safely contained, protect a smartphone screen, or serve as a foundation for electronic components. But when it comes to controlling heat, this familiar material still holds…
