Jacob Haqq-Misra, Ravi Kopparapu, and Eric Wolf attempt to address this question in a recent paper titled “Why do we find ourselves around a yellow star instead of a red star?” and published in International Journal of Astrobiology.
A Coronal Mass Ejection means that the corona, a layer of the sun, explodes, ejecting particles into space. Supernova cosmic rays or interstellar clouds could be the possible scenarios for strong radiation.
From chemistry to biology to social networks, specific shared principles should guide how information is organized and how it cycles through these stacks. If this theory of common principles can be demonstrated, we would gain a deeper understanding of the flow of information through life.
An over-the-counter hormone supplement called melatonin, typically made from animal pineal glands or synthesized in a laboratory, was tested on rats in the present study to see if it would be able to protect the intestines of rats treated with radiation.
Radio astronomers working with a radio dish telescope detected something a bit unusual. They were seeing a very fast radio burst, faster and more irregular than any signal in the history of radio astronomy. This radio burst was coming at very short time scales, lasting just a few milliseconds. The signal was irregular, very fast, and strong. This rapid burst has been something of a mystery since it was first discovered.
