LAKING PATTERN SIGNATURES. "Metamorphic code is code that when run outputs a logically equivalent version of its own code under some interpretation. This is used by computer viruses to avoid the pattern recognition of anti-virus software." https://lnkd.in/d8eMfUk View in LinkedIn

NEVER THE SAME. "Material metamorphosis does exist in real life. For instance, shape memory polymers have the ability to transform back to their parent shape when heated. Metamorphic computer viruses have the ability to change their shape by themselves from one form to another, but they usually avoid generating instances that are very close to their parent shape." (Claytronics and programmable matter). https://lnkd.in/d_2z5qc View in LinkedIn

METAMORPHIC VIRUSES. "Metamorphics are body-polymorphics." Metamorphic viruses do not have a decryptor or a constant virus body but are able to create new generations that look different. They do not use a data area filled with string constants but have one single-code body that carries data as code." https://lnkd.in/d_2z5qc View in LinkedIn

IMMUNE ESCAPE. "A program can metamorph by translating its own code into a temporary representation, edit the temporary representation of itself, and then write itself back to normal code again. As this process is done on the entire virus the engine also undergoes changes and the whole virus changes with it. The change is made, of course, to attempt to avoid scanners." Not dissimilar to cancer cells. https://lnkd.in/eAcnzhY View in LinkedIn

MORPHING CODE. "Metamorphic viruses do not have a decryptor and do not “unpack” to give a constant virus body like polymorphic viruses do. However, they are able to create new generations of the virus that look different." https://lnkd.in/eXJNZSa View in LinkedIn

CUE IDENTITIES. "The identity of the cue(s) that trigger polarization, and whether this cue involves microtubules, has been an ongoing controversy." https://lnkd.in/dAxynvD View in LinkedIn

INSCRUTABLE. "Self-modifying code is notoriously hard to understand and therefore very well suited to hide program internals. Self-modifying code has a long history of hiding the internals of a program. It was used to hide copy protection instructions in 1980s MS DOS based games." https://lnkd.in/dzxTmXb View in LinkedIn

DOWNSTREAM EFFECTS. "The asymmetrically localized Par proteins in turn shape the distributions of cytoplasmic factors that specify different developmental potentials. They also shape the distributions of cortical factors that position the mitotic spindle, and thus the first cleavage furrow, to segregate correctly developmental potentials to unequally sized daughters." https://lnkd.in/dAxynvD View in LinkedIn

THE SPERM CUE. "Acting on an essentially unpolarized cell, the sperm cue triggers a rapid reorganization of the cell cortex, accompanied by the de novo enrichment of conserved polarity determinants known as Par proteins within complementary anterior and posterior cortical domains." https://lnkd.in/dAxynvD View in LinkedIn

DIVERSITY FROM FEW SYSTEMS. "Registration of the cleavage plane with the axis of polarity then ensures differential inheritance of these potentials. With respect to cell fates, the output of these asymmetric divisions is amazingly diverse, yet the embryo seems to accomplish this diversity through variants of a few conserved symmetry-breaking systems." https://lnkd.in/dAxynvD View in LinkedIn
