Plastic and Reconstructive Surgery, 1965
A nodular growth appeared on the wrist of a healthy man (Fig 1) and reached a diameter of 1.5 cm within three weeks. It was hard, red, and shiny with an umbilicated central plug. A small biopsy specimen taken from the edge of this lesion was interpreted as well-differentiated squamous cell carcinoma.

We are increasingly seeing computer systems which are expected to function without operator intervention. This is perhaps acceptable for running computer networks or traffic lights; however, we are now seeing computer systems deployed to qualitatively influence human judgments such as rulings on legal disputes or fitness for work to evaluate disability

Self-healing superamphiphobicity
Chem. Commun., 2011Biomimetic self-healing superamphiphobicity is reported on a rough alumina surface with a large number of nanopores that act as nanoreserviors for low surface energy materials that can consecutively release and heal the damaged surface.

AbstractSelf‐healing is a natural process common to all living organisms which provides increased longevity and the ability to adapt to changes in the environment. Inspired by this fitness‐enhancing functionality, which was tuned by billions of years of evolution, scientists and engineers have been incorporating self‐healing capabilities into synthetic

Advanced Materials, 2010
AbstractSelf‐healing materials are able to partially or completely heal damage inflicted on them, e.g., crack formation; it is anticipated that the original functionality can be restored. This article covers the design and generic principles of self‐healing materials through a wide range of different material classes including metals, ceramics ...

Salmonella “RecAmends” self-healing
Cell Host & Microbe, 2021Persistent bacteria contribute to antibiotic treatment failure, potentially fueling resistance. Persisters must survive host defenses while retaining infective capacity after antibiotic cessation. In this issue of Cell Host and Microbe, Hill et al. identify bacterial RecA as a DNA repair factor that allows intracellular bacteria survival, regrowth, and

Self-healing is an intrinsically exciting concept as it applies to the process of recovery, a commonplace phenomenon found in living organisms. Self-healing of artificial materials is as beneficial to living creatures as it is to materials science, wherein the effect can considerably prolong lifetimes.

Self-healing of fractured diamond
Nature Materials, 2023Materials that possess the ability to self-heal cracks at room temperature, akin to living organisms, are highly sought after. However, achieving crack self-healing in inorganic materials, particularly with covalent bonds, presents a great challenge and often necessitates high temperatures and considerable atomic diffusion.

Self‐Healing Colloidal Crystals
Angewandte Chemie International Edition, 2009AbstractHealing hands: A complex interplay between colloidal and polymeric energetics in microgel self‐assembly behavior results in soft colloidal assemblies with self‐healing properties. Repulsive soft spheres can adopt highly compressed conformations in colloidal crystalline lattices without directly contacting the nearest neighbors (see picture ...

Proceedings of the 2007 Workshop on New Security Paradigms, 2008
Most attacks on computing systems occur rapidly enough to frustrate manual defense or repair. It appears, therefore, that defense systems must include some degree of autonomy. Recent advances have led to an emerging interest in self-healing software as a solution to this problem. It is not clear, however, if the effort to create self-healing mechanisms
