Looks like the Sun has a cold and is oozing plasma.
Saw the video via APOD: "The Sun's photosphere has thousands of bumps called granules and usually a few dark depressions called sunspots. The above time-lapse movie centered on Sunspot 875 was taken last year by the Vacuum Tower Telescope in the Canary Islands of Spain using adaptive optics to resolve details below 500 kilometers across. Each of the numerous granules is the size of an Earth continent, but much shorter lived. A granule slowly changes its shape over an hour, and can even completely disappear. Hot hydrogen gas rises in the bright center of a granule, and falls back into the Sun along a dark granule edge."

After posting some microtubule stuff, it's time for an entry about mRNA.
I see that ol' amino acid chestnut, Mr. W, who also goes by the moniker of tryptophan, is making the "science of Thanksgiving" rounds here at SB.
Traditionally, gene expression patterns were seen as mostly dependent on transcription ... yes those nasty bits of DNA that seemed to be ignored by most "science journalists".
