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 ...

The mechanism of antibiosis involves an interaction between two organisms, where one organism produces substances such as toxins, enzymes, or antibiotics that harm another organism, particularly pathogens. [6] These interactions reduce pathogen viability of pathogens, limit the spread of disease, and enhance plant protection.
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.
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.
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 ...

Photoprotection is the biochemical process that helps organisms cope with molecular damage caused by sunlight.Plants and other oxygenic phototrophs have developed a suite of photoprotective mechanisms to prevent photoinhibition and oxidative stress caused by excess or fluctuating light conditions.
