Reply to comment by Jale89 in I just learned that the known shortest DNA in an “organism” is about 1700 base pairs in a certain virus. Is there a minimum amount of “code” required for an organism (or virus) to function in any capacity? by mcbergstedt

> they could potentially go even further, if there are genes sets where knocking out only single components was lethal, but knocking out the whole set was survivable, so there's potential to go even further.

That’s got to be maddening, having to account for various combinations within your original problem.

Reply to comment by abalawadhi in How does dish soap eliminate bacteria? by [deleted]

Even if they don’t rupture, they’re getting washed away by magnitudes more water than they can deal with. (In a similar vein, I find general spray cleaners just as effective on unwanted insects as insecticides, but with no awful odors/volatiles, and ready to wipe clean.)

Bacteria can produce biofilms in an attempt to hold position, hence the need for scrubbing to break up their defenses.

Some soaps used to have antibacterials, but that just resulted in resistant bacteria wherever they ended up.

Reply to ELI5: How is that Pantone colors don't have direct RGB counterparts? by ExternalUserError

RGB is a system for adding colors of light. This is always at odds with printed work that relies on blocking colors of light from reflecting off a page, as pages generally do not produce their own light.

RGB focuses on three specific wavelengths of light closely corresponding to the three colors most peoples' eyes are most sensitive to. Pantone relies on fourteen base pigments, and attempts to match along the entire spectrum of color.

Meanwhile, Pantone focuses on getting consistent color. A bottle of a certain ink bought decades ago should match with a package of dye purchased in the present day. Even if the pigments are produced using different chemicals, they attempt to match with each other under similar lighting conditions.

Something we take for granted with RGB is that results vary between different devices. The red color chosen by one manufacturer may differ from the red used by another. There can be variation within the model line of a certain device. The same device may show the same color values differently under different conditions (e.g. full daylight vs lights out, blue light filter, new vs old monitor).

Even #000000 black, which every device treats as the absence of light, may not match between different devices. Typical monitors will deflect as much light as they can, but cannot fully prevent a backlight from showing to some degree. Some newer monitors stop generating light, and so produce a darker black.

Reply to comment by theclash06013 in ELI5: Why does MSG make food taste so irresistible? And why is everyone against it? by theinvincible-dosa

Adding on, glutamic acid is widely found in meats, and in certain other foods such as seaweed, kelp, and yeast. (Yeast extract may appear in some ingredient lists as a sneaky way of adding glutamates without listing MSG.) Your body needs and wants this.

Meanwhile, the sodium part of MSG might cause some concerns if you have a restrictive diet. MSG is just one of many, many sodium sources that aren't table salt.
