Now you can get the dope on happiness [exec summary - it's complicated]:
Palomino, who should know better, recently sent me a little movie-gif with an explanatory caption "What you see is a myosin protein dragging an endorphin along a filament to the inner part of the brain's parietal cortex which creates happiness. Happiness. You're looking at happiness.”
We all have our domain of expertise. Jeremy Bentham, spent his life thinking about political philosophy so was able to be confident in his dismissal of The Declaration of the Rights of Man and the Citizen as "nonsense on stilts". Last Saturday I was talking to our amazing diagnostic plumber and was able to share the old joke about the itemised invoice. Michael-the-plumber seems to be able to work out what's wrong with pretty much any system involving liquids valves spiggots and/or electricity . . . and fix it with €30 in parts and about the same in labour. Me, I teach Human Physiology, so I've had to internalise the relative size of the working parts of a cell. I wish I could transmit this knowledge to my students! I've tried to present it as a scale-of-the-solar-system metaphor, with only partial success.
ANNyway, the scaling of the endorphin /myosin / happiness-is-a-drag cartoon seemed all wrong but it took me 10 minutes to tie down some numbers so that any scale bar could be shown to be internally inconsistent. My initial response there fore was :
Yerp? It's a cartoon, X. And whatever is going on the caption doesn't match the scaling. Myosin is a long string of a protein about 2000 AA / 160nm long. Endorphins OTOH are chunky but much small molecules about 30 AA long. The huge green thang in the gif could be a cell - 10,000nm in diameter but it looks too small to be 100x wider than the myosin is long. So I'm at a loss but my skeptic hat is throbbing.
I then went off to google the source of the gif and its caption: "myosin endorphins" and found that many people had been trawling the interweb along similar tracks "myosin endorphins snopes" was, for example, one of the top Google guess-the-punter's-mind completions. This led me to a much more realistic answer: "That's kinesin transporting a vesicle along a microtubule."
So I gave myself a big duh-slap and wrote:
Silly me. If it's too big to be a macromolecule and too small to be a cell it must be a sub-cellular organelle:
And cited myself about questions of size as above. Everything I know is in The Blob, but there's so much crud in there that it's hard to find relevant bits of information. What's a vesicle? It's a small membrane-bound thing of which every cell has dozens to hundreds. The vesicle in the cartoon might be loaded with endorphins, in the same way as a lysosome is loaded with hexosaminidase, but conflating the two is like saying that the passenger is the bus.
According to Google it's my birthday today. It is not. Like the happiness-is-a-drag meme has been circulating as truth for the last 6 months, Today-is-Bob's-bday is another example of GiGo - garbage in garbage out. I've no idea who / when / how Google+ acquired the incorrect data. It's always best to put the truth down in these cases, that way you're not required to remember your lies. Yest, I had to fire-up the new wifi dongle over the phone with an operative who was required only to speak to the Named Subscriber. As The Beloved is in France for two weeks I had to stoutly assert that, like the Boy named Sue, my folks had called me Roberta - and I knew her birthday when asked: phew!
