When a current is applied to a thin layer of tungsten diselenide, it begins to glow in a highly unusual fashion. In addition to ordinary light, which other semiconductor materials can emit, tungsten diselenide also produces a very special type of bright quantum light, which is created only at specific points of the material. It consists of a series of photons…

Analysis of Galileo’s Jupiter entry probe reveals gaps in heat shield modeling
The entry probe of the Galileo mission to Jupiter entered the planet’s atmosphere in 1995 in fiery fashion. As the probe descended from Mach 50 to Mach 1 and generated enough heat to cause plasma reactions on its surface, it relayed data about the burning of its heat shield that differed from the effects predicted in fluid dynamics models. New work…

Clusters are the most massive gravitationally bound objects in the universe and form (according to current ideas) in a…
