Physicists at Radboud University have outlined a theoretical model suggesting that compact stars and their remnants could, in principle, slowly lose mass through a Hawking-like radiation process even ...

Radiation is energy that moves from one place to another in a form that can be described as waves or particles. We are exposed to radiation in our everyday life. Some of the most familiar sources of ...

The longest-lived stars in the cosmos may not survive for 101100 years after all. A new theoretical estimate places the effective upper bound far lower, at 1078 years for white dwarfs, suggesting that ...

Radiation from used nuclear fuel could be used to create a valuable fuel additive needed for renewable biodiesel, scientists in Slovenia and the UK have shown. The research highlights that there are ...

Components of a typical laser include gain medium, laser pumping energy and resonant optical cavity. The output frequency of most lasers is fixed or within a small range, and it is difficult to ...

A team from the Institute of Chemical Technology (ITQ), a joint research centre of the Universitat Politècnica de València (UPV) and the Spanish National Research Council (CSIC), and the Institute of ...
