Explanation:

Scientists from Indian Institute of Geomagnetism (IIG), an autonomous institute under the DST have recently developed a theory that helps understand the complicated nature of Sun-Earth interaction's happening in the magnetosphere-- an area of space around Earth that is controlled by the Earth’s magnetic field.

• This new theory has opened up a plethora of opportunities to unlock the mysteries of the ion-hole structures (a localized plasma region where the ion density is lower than the surrounding plasma).
• They have completely ruled out the necessity of the upper limit in the temperature ratio between ions and electrons for the generation of a special kind of wave called Bernstein Green Kruskal (BGK) waves, named after the scientists who predicted this wave. They revealed that the electrons that are not part of ion hole dynamics also play a vital role.
• The new theory developed by the IIG team sheds light on the nature's greatest mystery that causes phenomena ---plasma transport and heating of plasma -- the fourth state of matter after solid, liquid, and gas, which is the most natural and widely observed state of matter in the entire universe.

Hence both statements are correct.
