Georges Lakhovsky (1869-1942) was a Russian engineer, scientist, author and inventor. His controversial medical treatment invention, the Multiple Wave Oscillator, is described as having been used by him in the treatment of cancer. Lakhovsky published books and articles that claimed and attempted to demonstrate that living cells emit and receive electromagnetic radiations at their own high frequencies. In 1939 he published "The Secret of Life: Electricity, Radiation and Your Body" in which he claimed and attempted to demonstrate that good or bad health was determined by the relative health of these cellular oscillations, and bacteria, cancers, and other pathogens corrupted them, causing interference with these oscillations. Numerous depictions pictured in the book supposedly have Lakhovsky in a Paris, France hospital conducting clinical research treating cancer patients with before, during, and after photographs.

Klimarådet udgav d. 14. aug. 2024 en analyse af Danmarks klimaregnskab, hvor det bl.a. foreslås, at en del af forbruget af kød og mælk ersattes af kultiveret/dyrket kød og mælk. Dette kan ske ved dyrkning af stamceller fra husdyr, eller ved at man dyrker gærceller, som har fået gener fra køer til at producere mælk. Miljøfordelene er bl.a. meget mindre brug af krævet jordareal, og derved frigivelse af arealer til biodiversitet. Bogen opridser mulighederne for en disruption-omvæltende produktion af proteiner på basis af denne nye forskning. Emnet er højaktuelt, hvilket ses af at nogle amerikanske delstater i 2024 har forbudt denne forskning!

Reactive Oxygen Species (ROS) are molecules generated naturally during cellular metabolic processes. They act as signaling agents that oversee specific biochemical pathways, playing a vital role in cell function and survival. However, an imbalance in ROS signaling or excessive ROS production can have harmful effects on the pathophysiology of diseases. ROS are crucial to cell signaling and are involved in various physiological processes. They modulate gene expression, regulate cell cycle progression, and influence immune responses. Although ROS are essential for normal cellular functions, an overabundance of these molecules can lead to oxidative stress, causing DNA damage, lipid peroxidation, and protein oxidation, adversely impacting cell function and leading to various diseases. Therefore, it is critical to regulate ROS levels precisely to maintain cellular homeostasis.

The Physics of Protein Structure and Dynamics looks at various aspects of protein structure and dynamics from a physico-chemical point of view. It goes into some depth regarding the description of non-covalent forces that determine the relative stability of folded and unfolded proteins. Anharmonic protein dynamics involving motions between different minima of a rugged Gibbs energy landscape is described in great detail. The book combines various aspects of the protein folding/unfolding processes with an overview of intrinsically disordered proteins, which have attracted considerable interest of the protein community over the last 25 years but are thus far underrepresented in classroom-oriented textbooks. The book looks at protein folding and intrinsically disordered proteins as heavily interrelated topics that need to be viewed together. Furthermore, it presents some basic physico-chemical aspects of protein/peptide self-assembly into nanoscale fibrils. Intrinsically disordered peptides and proteins play a major role particularly in aggregation and self-assembly processes that lead to various diseases (Alzheimer, Parkinson, Huntington, Mad-Cow). Therefore, the relevance of protein disorder for protein self-assembly deserves a closer look. Protein self-assembly cannot be separated from protein folding since it is frequently the product of misfolding. With regard to modern theories, the folding processes are linked to insights on protein dynamics and the discovered relationship between proteins and spin glasses.
