Solanaceae: I tried another sunberry, and it didn't have the nasty flavor of the previous, which may not have been fully ripe. It didn't have much flavor at all, actually, except quite a bit of sweetness. And the sweetness lingered; I'm not convinced it was all sugar, may be dulcamarin glucoside?

All in all, I'd try cooking a tartlet with them, pies being what people say they're good for, if I get enough to fill a microscale cookery setup. (What do I have that's smaller than a muffin pan?)

words of the day:

smokejack: "is an engine used for the same purpose as the common jack; and is so called from its being moved by means of the smoke, or rarefied air, ascending the chimney, and striking against the sails of the horizontal wheel which being inclined to the horizon, is moved about the axis of the wheel AB (plate XXI. fig 1.), together with the pinion C, which carries the wheels D and E; and E carries the chain F, which turns the spit."

heart-shake: "When it consists of a single cleft extending across the pith it is termed simple heart shake. Shake of this character in straight-grained trees affects only one or two central boards when cut into lumber, but in spiral-grained timber the damage is much greater. When shake consists of several radial clefts it is termed star shake."

radiotrophic fungi: black Chernobyl molds use melanin to grow on gamma rays. I think I learned that once before, but it's not dulled by repetition.

xylem cavitation: "In some trees, the sound of the cavitation is clearly audible, particularly in summer, when the rate of evapotranspiration is highest." Audible especially if you can hear in the hundreds of kilohertz, the web seems to be hinting.

Himmler: deeply appalling.

I've read somewhere that corn even produces audible cavitation noises.

Ah, it sounds from this corn-cavitation article like the cavitation is in the audible range too, but the ultrasound range is convenient for sensing because there's less ambient noise there(?).
