Dictyopterene

Dictyopterenes are a group of chemical compounds that are naturally present in marine and freshwater environments. They are sexual attractants, or pheromones, found with several species of brown algae (Phaeophyceae). The chemical formula of dictyopterene A is trans-1-(trans-1-hexenyl)-2-vinylcyclopropane. The chemical formula of dictyopterene C' is 6-butylcyclohepta-1,4-diene.[1] Dictyopterene A can be extracted from the essential oil of algae of the genus Dictyopteris.[2]

gollark: I mean, it's not too bad if your *cable* wears out, but it *is* if the device's does.
gollark: (somehow I wrote microUSB there, oops)
gollark: I'm comparing it to USB-A for point 4.
gollark: <@!111608748027445248> - Too many different things over identical looking physical connectors: a "USB-C" port might support power-delivery *input*, power-delivery *output*, Thunderbolt, two different incompatible kinds of video output, and various speeds from USB 2.0 to USB 3.2 Gen2x2 (whyyy).- The ports on devices can end up wearing out problematically, though I don't know if this is better or worse than on competitors like Lightning or µUSB.- A lot of peripherals still don't support it, though this is hardly *its* fault.- I think the smaller connector means you can't put as much weight on it safely, for bigger USB stick-y devices, though I am not sure about this.
gollark: Eh. Sort of. It has its own problems.
