Abductin is one of the five rubber-like solids used by animals to provide elasticity in biological systems; the others are elastin, resilin, spider silk, and ColP.

Abductin appears exclusively in the hinge ligament of bivalve mollusks, and the name comes directly from its function: abductin ligaments oppose the adductor muscles that open and close the valves (shell halves) of the Bivalvia. When the shells close the abductin is compressed; when the adductor muscle relaxes the energy stored in the abductin pops the valves apart. Incidentally, abductin is the only biological elastomeric protein designed to work primarily under compression, rather than tension.

Abductin shows a fairly wide range of efficiency, with the most effective energy storage being found in the abductin of swimming bivalves; some bivalves, most particularly the scallops (Pectinidae) swim by rapidly opening and closing their valves, up to

I've been running Linux as my only computer OS for probably ten years, and have been very happy overall with the tech and how to use it. Dealing with the community is sometimes a litttle challenging; many people find there are many gatekeepers, many opinions and yes, still many holy wars. One is the title reference, that "it's not 'Linux', it's GNU-Linux!" Frankly I see this as off-putting to many, potentially a barrier to adoption; yes, there can be some toxicity within the communities.

I found it charming for a couple years afterwards
to think we were married
at home:

She was there
that was home.
