Tracking the Diffusion of Signal Proteins in Escherichia Coli

Authors: Herbert Weidner
Comments: 6 Pages.

We describe a fast computational model to study the signal transduction in E. coli chemo­taxis. It allows to trace the places and chemical reactions of individual molecules in a cell as a function of time. From the spatial resolution of the model and the known diffusion constant of the proteins, a time step of 3 µs is calculated for the simulation.

Reproductive Cloning

Authors: Ian von Hegner
Comments: 20 Pages.

Progressiv forkortelse af telomere ved DNA replikation er blevet sat i forbindelse med cellulær ældning. Hvad vil der ske med dyr, fremkommet ved somatisk kerneoverførsel, hvis differentierede celler fra voksne dyr med forkortede teleomerelængde benyttes til at starte embryo udvikling? Vil de forkortede telomere påvirke deres livslængde eller udvikling, eller er de forkortede telomere fra donerceller blevet rekonstrueret til fuld længde i klonede dyr?

Recognition from Description Through Synthesis and Reduction to Theory and Model

Authors: Andrzej Gecow
Comments: 9 Pages. in Polish

The half a century attempts to transmit the results of the theoretical work on the biological issues which used the methodology of physics, gave an insight into the methodological limitations resulting from the stereotypes of thinking in biology. It is primarily a lack of interest in the pursuit to deductive theory. Abstraction and deduction - the basis of physics, is despised and omitted as speculation, which creates a blockade in the development of theory in biology. The process of this development stops at an analysis that should (and does not do) reduce the sufficient conditions noted in the description to the necessary and sufficient conditions, ie. to determine the reasons for the phenomena being considered. Determination of the necessary conditions is the basis of reduction, which in the applied reductionism is not noticed. This chapter is not a recognized knowledge imparted authoritatively to use, nor fight against the official position of biology, but a collection of arguments against conservative stereotypes, to compare with other more elaborate sources on the reader's own responsibility to work out his own view rather than uncontrolled take over of the defective tradition.

Materials for Discussion of Methodological Limitations Resulting from the Stereotypes of Biologists Thinking

Authors: Andrzej Gecow
Comments: 18 Pages. in Polish

Attempts to communicate the results of theoretical works on the evolutionary biology using the methodology of physics have not yielded results for half a century, but have led to the recognition of methodological limitations stemming from the stereotypes of thinking in biology. It is primarily a lack of interest in the pursuit of deductive theory. Abstraction and deduction - the basis of physics, are despised and omitted as speculation, which creates a blockade in the development of theory in biology. As a basis for this diagnosis, five reviews of the text addressed to “KOSMOS” have been analyzed, which led to the conclusion that the text, because of the thesis contained therein, is unreadable to biologists. This study is the basis for a wider discussion in a separate publication.

Current Return to Lamarck in Agreement with Darwin

Authors: Andrzej Gecow
Comments: 12 Pages. in Polish

The terms ‘Darwinism’ and ‘Lamarckism’ mean different things to different people. Nowadays, they are rarely used in a historically correct way – clime Jablonka and Lamb, the scientists that mainly contribute to proving than not only genes can curry hereditary information and new hereditary channels show characteristic of Lamarckian mechanisms. Especially Lamarckism was seen in false and superficial way in lot of aspects. The inheritance of acquired characters was connected to Lamarck. It was rejected too radically. Today it revives but mainly not basing on epigenetic inheritance. Generally Lamarckian mechanisms increase in the complex and diverse ways the chances of accurate adaptive changes, so they no longer look like a random, appear as ‘effects of instructions’ or ‘directed variations’ but these ‘instructions’ have been previously acquired through Darwinian natural selection. The richness of these phenomena causes great difficulty of their brief describtion. Lamarckian dimension of evolution is now known better. This phenomena cannot be explained in the range of Modern Synthesis assumptions. It does not mean, that MS is false and should be rejected. Lamarckian mechanisms are created by Darwinian natural selection, but their explanations need wider assumptions, than are a basis of MS, means Extended Evolutionary Synthesis is necessary. This theme is one of the main in current discussion.
