This evidence that the Antikythera mechanism was not unique adds support to the idea that there was an ancient Greek tradition of complex mechanical technology that was later, at least in part, transmitted to the Byzantine and Islamic worlds, where mechanical devices which were complex, albeit simpler than the Antikythera mechanism, were built ...
Michael T. Wright, FSA (Born: 16 June, 1948) is a former curator of mechanical engineering at the Science Museum and later at Imperial College in London, England. [1] He is known for his analysis of the original fragments of the Antikythera mechanism and for the reconstruction of this Ancient Greek brass mechanism.

Plant cells differ from animal cells in that they have a cell wall. During mitosis, the new cell wall is built by the formation of a cell plate starting in the center of the cell. This process is facilitated by a phragmoplast, a microtubule array unique to plant cell mitosis. The building of cell plate and ultimately the new cell wall requires ...
In plant immunology, the hypersensitive response (HR) is a mechanism used by plants to prevent the spread of infection by microbial pathogens.HR is characterized by the rapid death of cells in the local region surrounding an infection and it serves to restrict the growth and spread of pathogens to other parts of the plant.
It was discovered by sponge divers off Point Glyphadia on the Greek island of Antikythera in 1900. The wreck yielded numerous statues, coins, and other artifacts dating back to the fourth century BC, as well as the severely corroded remnants of a device many regard as the world's oldest known analog computer, the Antikythera mechanism.

Ethylene and auxin complement JA by influencing cell elongation and asymmetric growth, both critical for thigmomorphogenesis. Ethylene production increases in mechanically stimulated plants and is linked to radial expansion and stem thickening, traits that enhance structural stability against mechanical forces like wind.
