As we are not nocturnal animals by nature, then we must benefit from sunlight, in several ways. It then follows that we can deal with sunlight - maybe we need to be more in touch with how to deal with exposure. This research shows that we do not know all the ways that we use sunlight naturally, which is probably true of other environmental factors. I will be very interested in outcomes of further research. Is there any research about sunlight and cognition?

Sunlight benefits greater than skin cancer risk?
The radio emissions that we have observed have a certain shape to them. By analysing the shape of these radio waves, we can tell that they have been produced by processes similar to those that generate radio emissions above the Earth's auroras. In light of this, we are pretty sure that they have been caused by the acceleration of charged particles along magnetic field lines. Whether on Earth or on other planets, auroras occur when charged particles are funnelled along the object's magnetic field towards its poles. When they hit the atmosphere, they cause it to glow. However, before this happens, special kinds of radio wave are emitted into space. This was actually the process by which Jupiter's magnetic field was discovered; before we even knew about Earth's radiation belts. The presence of these radio waves is a strong indication that auroras are occurring outside our solar system.
