  •   Trackable chemical substance for paint or rubber that can be tracked by a device#10186

    Hi Jon,

    An interesting question. Not sure about the application of this, but you can achieve traceability by adding a UV luminescent dye to the paint. As it absorbs and emits UV, you can easily trace it with a simple UV lamp. If you want to track rubber and are sure that no other metal is present, you can add some magnetic particles into it and trace it with a magnet.

  •   What is a Phosphate Buffer Used for?#10175

    Yes, phosphate-buffered saline can clean and dilute cells. It’s an isotonic solution, meaning it has the same osmotic pressure as the cells and it doesn’t harm them. It’s a very common solution used in cell culture and biological experiments.

  •   How humans with NDE (Near Death Experience) describe altered events?#10170

    There’s no definitive answer to this. The common explanation is that any out-of-the-world or altered perception of reality is due to hallucinations induced by enhanced brain chemistry while encountering a near-death experience.

    Explaining the source or rationale behind the hallucination is even more complex as they are influenced by a lot of physiological and psychological factors, including cultural exposure, memories, trauma, stress, preconceived spiritual and social beliefs and expectations about death, all causing a rush of heightened brain activity that creates neural pathways, giving a unique experience for every individual.

  •   When is a mutation in a virus or bacteria considered a new disease?#10112

    Welcome to Geekswipe, @wdj92.

    Mutations in viruses and bacteria don’t necessarily create a new disease. In some cases, it’s just the intensity of a disease that changes. And of course, mutations would altogether create a new set of symptoms for a significantly different disease and the immune responses will vary. So if that’s the case, then it can be considered as a ‘new disease’ caused by the same virus or bacteria.
