Mitochondria and the evolutionary roots of cancer

Cancer is a group of almost 200 diseases that involve variety of changes in cell structure, morphology, and physiology. Cancer phenotype is underlying several alterations in cellular dynamics with three most critical features, which includes self-sufficiency in growth signals and insensitivity to in

Quantum entanglement between the electron clouds of nucleic acids in DNA

Rieper, Anders and Vedral modelled the electron clouds of nucleic acids in a single strand of DNA as a chain of coupled quantum harmonic oscillators with dipole-dipole interaction between nearest neighbours. As a main result, the entanglement contained in the chain coincides with the binding energy

Implications of quantum metabolism and natural selection for the origin of cancer cells and tumor progression

Energy transfer in material solids is driven primarily by differences in intensive thermodynamic quantities such as pressure and temperature. The crucial observation  in quantum-theoretical models was the consideration of the heat capacity as associated with the vibrations of atoms in a crystalline

Wholeness and implicate order: “Deep” quantum chemistry and cell consciousness: quantum chemistry controls genes and biochemistry to give cells and higher organism’s consciousness and complex behavior

Bohm used the term ‘holomovement’ which is an unbroken and undivided totality and carries an implicate order which is he totality of an order including both the manifested and non-manifested aspects of the order. Non-local quantum phenomena reside in a subtler level than quantum level that is th

A new theory of the origin of cancer: quantum coherent entanglement, centrioles, mitosis, and differentiation

Low non-specific, low intensity laser illumination (635, 670 or 830 nm) apparently enhances centriole replication and promotes cell division, what is the opposite of a desired cancer therapy. In the contrary, centrioles are sensitive to coherent light. Then higher intensity laser illumination - stil

Variation in cancer risk among tissues can be explained by the number of stem cell divisions

Tomasetti and Vogelstein show that the lifetime risk of cancers of many different types is strongly correlated with the total number of divisions of the normal self-renewing cells maintaining that tissue’s homeostasis. These results suggest that only a third of the variation in cancer risk among t

Quantum Tunnelling to the Origin and Evolution of Life

Quantum tunnelling is a phenomenon which becomes relevant at the nanoscale and below. It is a paradox from the classical point of view as it enables elementary particles and atoms to permeate an energetic barrier without the need for sufficient energy to overcome it. Tunnelling is being of vital imp

Schimpansen belohnen Gefälligkeiten

Für uns Menschen ist es eine Selbstverständlichkeit: Wir belohnen andere als Zeichen unserer Dankbarkeit. Wissenschaftler der Max-Planck-Institute für evolutionäre Anthropologie und für Mathematik in den Naturwissenschaften in Leipzig haben nun ähnliche soziale Verhaltensweisen auch bei Schimpansen nachgewiesen. In einem Verhaltensexperiment belohnt ein Tier ein anderes mit Futter, wenn dieses ihm zuvor geholfen hat. Offenbar hat nicht erst der Mensch aus diesem Grund kooperiert, schon der Vorfahr von Mensch und Schimpanse hat offenbar aus einer ähnlichen Motivation heraus untereinander geteilt. Die Studie zeigt, warum Schimpansen dies tun und bestätigt Ergebnisse aus der Spieltheorie. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)

Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Wie die Zellen zu ihren Kraftwerken kamen

Evolutionsbiologie

Düsseldorf, 22. Juni 2017: Komplexe Zellen, so genannte Eukaryoten, besitzen neben dem Zellkern weitere abgeschlossene Zellbestandteile. Dazu gehören Mitochondrien, die Zellkraftwerke, welche früher eigenständige Bakterien waren. Wie es dazu kam, dass eine Zelle eine andere in sich aufnahm, hinterfragten Wissenschaftler vom Institut für Molekulare Evolution der Heinrich-Heine-Universität Düsseldorf (HHU) zusammen mit Kollegen aus den Niederlanden und der Slowakei. Ihre Ergebnisse publizierten sie kürzlich in der Fachzeitschrift Microbiology and Molecular Biology Reviews. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)

Familienleben als Sprungbrett für gemeinsame Jungenaufzucht

Similar Design, Different Genes: Miniature Weapons in the Animal Kingdom

In evolutionary convergence, two genetically unrelated organisms evolve similar traits, and biologists at Heidelberg University have now uncovered an example of convergence at the subcellular level in unicellular organisms and cnidarians. Together with colleagues from Canada, Assistant Professor Dr Suat Özbek and Prof. Dr Thomas Holstein have discovered that the two organisms developed similar miniature weapons for prey capture over the course of their evolution, although they share no common genetic basis. The Heidelberg researchers study the function and molecular structure of these „weapons systems“ at the Centre for Organismal Studies.

Gleichartige Bauprinzipien, unterschiedliche Gene: Miniaturwaffen in der Tierwelt

Sie verfügen über eine gleichartige Bauweise, dennoch sind sie genetisch grundverschieden: Das Prinzip der Konvergenz haben jetzt Biologen der Universität Heidelberg am Beispiel von Einzellern und Nesseltieren auf subzellulärer Ebene beschrieben. Beide Organismen haben im Laufe ihrer Evolution ähnliche Miniaturwaffen für den Beutefang entwickelt, ohne dass diese einen gemeinsamen stammesgeschichtlichen Ursprung besitzen, wie Privatdozent Dr. Suat Özbek und Prof. Dr. Thomas Holstein zusammen mit kanadischen Kollegen herausgefunden haben. Die Heidelberger Forscher untersuchen am Centre for Organismal Studies die Funktionsweise und molekulare Struktur dieser „Waffensysteme“.

Warum schwanken antarktische Krillbestände?

Der Antarktische Krill (Euphausia superba), eine der häufigsten Arten der Welt, ist Nahrungsgrundlage für viele Tiere im Südpolarmeer. Lange Zeit rätselten Wissenschaftler, warum die Größe der Krillbestände immer wieder stark schwankt. Ein internationales Team um Prof. Dr. Bernd Blasius, Institut für Chemie und Biologie des Meeres (ICBM) der Universität Oldenburg, und Prof. Dr. Bettina Meyer, Alfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung (AWI) und ICBM, zeigt nun: Vor allem Konkurrenz um Nahrung innerhalb der Population ist für die Schwankungen verantwortlich. Die Ergebnisse sind in der aktuellen Ausgabe des Fachmagazins „Nature Ecology and Evolution“ erschienen. (Mehr in: Pressemitteilungen – idw – Informationsdienst […]

New approach to antibiotic therapy is a dead end for pathogens

Kiel-based team of researchers uses evolutionary principles to explore sustainable antibiotic treatment strategies

The World Health Organization WHO is currently warning of an antibiotics crisis. The fear is that we are moving into a post-antibiotic era, during which simple bacterial infections would no longer be treatable. According to WHO forecasts, antibiotic-resistant pathogens could become the most frequent cause of unnatural deaths within just a few years.

Neuer Ansatz in der Antibiotikatherapie treibt Krankheitskeime in die Sackgasse

Kieler Forschungsteam nutzt evolutionäres Prinzip zur Entwicklung nachhaltiger Behandlungsformen in der Antibiotikatherapie

Die Weltgesundheitsorganisation WHO warnt immer eindringlicher vor einer dramatischen Antibiotikakrise. Sie befürchtet, dass eine post-antibiotische Ära kurz bevorsteht: Bakterielle Infektionen, die sich früher gut bekämpfen ließen, wären dann nicht mehr behandelbar. Antibiotika-resistente Krankheitskeime könnten laut Vorhersage der WHO binnen weniger Jahre zu den häufigsten Verursachern nicht-natürlicher Todesfälle werden.

“Pregnant” Housefly Males Demonstrate the Evolution of Sex Determination

An international team headed up by researchers from the University of Zurich has discovered the gene that determines the male sex in houseflies. Surprisingly, the sex-determining mechanisms are not the same for all houseflies – they depend on where the insects live. This knowledge not only helps us better understand the evolution of sex determination, but also aids in the control of agricultural pests or carriers of disease.
