RNA–Mediated Epigenetic Heredity

Plasma created by sunlight and RNA–mediated epigenetic heredity

Australian student confirms that giant plasma tubes are floating above Earth Excerpt: The region of space around the Earth occupied by its magnetic field, called the magnetosphere, is filled with plasma created by the atmosphere being ionised by sunlight. My comment: Scientists have believed in the creation of these structures for more than 60 years. Now visual evidence confirms structures exist that are created by sunlight on contact with the Earth’s atmosphere. This reminds me of what someone who was…

Are mutations beneficial?

Researchers develop non-invasive method to detect tumor-causing mutations in saliva Excerpt: “…a multiplexible electrochemical sensor uses electrode chips to enable vesicular entities in saliva called exosomes to rapidly release molecular constituents (DNA, RNA and proteins) while simultaneously detecting any mutations in tumor-causing DNA sequences. The total detection time is less than 10 minutes and required a small saliva sample.” My comment: This news about multiplexing attests to the complexity of systems biology, which links amino acid substitutions to mutated DNA…
