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

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

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

Sehschwäche in der Schwangerschaft: Bei diesen Warnzeichen sollten Sie zum Augenarzt

Jede sechste werdende Mutter ist während der Schwangerschaft von Augenproblemen betroffen. Die meisten Beschwerden sind harmlos und bilden sich nach der Schwangerschaft von selbst zurück, sagen Experten der DOG – Deutsche Ophthalmologische Gesellschaft. In seltenen Fällen können aber auch Symptome auftreten, die auf einen Schwangerschaftsdiabetes oder eine Schwangerschaftsvergiftung – die sogenannte Präeklampsie – hinweisen. Bei wechselnder Sehschärfe, Flimmern oder Schatten vor den Augen oder bei komplettem Sehverlust sollten Schwangere sofort einen Augenarzt aufsuchen.

Durchbruch in der Telomer-Forschung: nicht die Länge ist entscheidend

Bislang ging man davon aus, dass die Länge der Telomere ausschlaggebend für die Entstehung von Krankheiten wie Krebs oder Diabetes ist. Laut neuen Forschungsergebnissen aus Sydney geht es jedoch nicht um die Länge, sondern um die Struktur der DNA-Segmente. In weiteren Studien soll nun herausgefunden werden, inwieweit die menschliche Gesundheit mit der Telomer-Gesundheit zusammenhängt.

Diabetes raises risk of cancer, with women at even greater likelihood, a major new study has found

A global review involving almost 20 million people has shown that having diabetes significantly raises the risk of developing cancer, and for women the risk is even higher. Researchers also found diabetes (type 1 and type 2) conferred an additional risk for women, compared to men, for leukaemia and cancers of the stomach, mouth and kidney, but less risk for liver cancer.

Weaponizing oxygen to kill infections and disease

19. Aug. 2018

The life-threatening bacteria MRSA can cripple a medical facility since it is resistant to treatment. But scientists report that they are now making advances in a new technique that avoids antibiotics, instead using light to activate oxygen, which wipes out bacteria. The method also could be used to treat other microbial infections, and possibly even cancer. (Mehr in: Cancer News — ScienceDaily)

Insight into development of lung cancer

18. Aug. 2018

Lung cancer results from effects of smoking along with multiple genetic components. A new study identifies two main pathways for the role of chromosome 15q25.1 — a leader in increasing susceptibility to lung cancer — in modifying disease risk. One pathway is implicated in nicotine dependence. The other plays a part in biological processes such as nutrient transfer and immune system function. The findings increase our understanding of lung cancer cause and development. (Mehr in: Cancer News — ScienceDaily)
