A dynamic self-organized morphology is the hallmark of network-shaped organisms like slime moulds and fungi. Organisms continuously re-organize their flexible, undifferentiated body plans to forage for food. Among these organisms the slime mould P. polycephalum has emerged as a model to investigate how organism can self-organize their extensive networks and act as a coordinated whole. Cytoplasm...
Despite immense progress in neuroscience, we remain restricted in our ability to construct autonomous, behaving robots that match the competence of even simple animals. The barriers to the realisation of this goal include lack of knowledge of system integration issues, engineering limitations and the organisational constraints common to many research laboratories. In this paper we describe our ...
The major technical and conceptual advances in cognitive science have always been connected directly or indirectly to artificial intelligence and, over the last 20 years, specifically to the field of autonomous robotics. It is thanks to the elegance and practical value of work in various regions of robotics that certain fundamental questions in cognitive science can be revisited. This is partic...
Defining an organism has long been a tricky problem for biologists. Recent work has shown how an approach based on adaptation can solve this problem, giving a conceptually simple two-dimensional measure of 'organismality'.
Copper is an essential micronutrient for human bodies, whose distribution in different organs and tissues, metabolism and physiological impact is not thoroughly explained yet. Further issues which need clarification are the exact composition and constitution of its combinations with other elements, the physiological impact of copper and copper-enzymes in sickness and health. Biomarkers for iden...
This review presents literature data on the prevalence, clinical picture, risk factors of development and modern approaches to diet therapy disease caused by Clostridium difficile (С. difficile). Particular attention is paid methods medical nutrition, taking into account symptoms intoxication organism. Data possibility using domestic products dietary nutrition treatment for restoration function...
by the food provided at these events. Large populations in fast food establishments further support their association with food. Yet little is known about the biology of Utensilus plastica (common name: plastic eating utensil). We have conducted an in-depth study of this easily overlooked species and discovered that it possesses a number of characteristics which make it an excellent model organ...
So, 21 CFR 211.113 limits the discussion to “products not required to be sterile” and 21 CFR211.84 states that the concern is “microbiological contamination that is objectionable in view of its intended use” leaving 21 CFR 211.165 to require lab testing relevant to “drug product required to be free of objectionable microorganisms”. This clearly defined concept of an “objectionable” organism the...
Choi^ra is almost universally attributed to the cholera vibrio, first discovered by Koch in 1883, and accepted, though not entirely without faint murmurs of questioning-, since. A doubt seems always to have existed as to the actual role played by t'he cholera vibrio, partly owing to the fact that a disease resembling cholera cannot be produced in experimental animals. Whilst to a certain extent...
Drift or downstream dispersal is a fundamental process in the life cycle of many riverine organisms. In face rapidly declining freshwater biodiversity, there need to enhance our capacity study drift organisms, by overcoming limitations traditional labour-intensive sampling methods that result data low temporal and spatial resolution. To address this need, we developed new technology, Riverine O...
