Stephanie Seneff: Glyphosate, EMF and Water, Vitamin D vs Sunshine

Episode 7 of Conversations with Dr. Cowan and friends is with the brilliant MIT researcher Dr. Stephanie Seneff today. In this interview, we cover many subjects having to do with circulation, Covid, glyphosate and the role of vitamin D in health and illness. Stephanie knows the medical literature on these subjects in a way that few others do. Some of her conclusions will surprise and challenge you. For example, she makes a compelling case that vitamin D supplementation is not a good idea.   My website:


Cytoskeletal microtubules have long been conjectured to have piezoelectric properties. They have been shown to behave as nematic liquid crystals which oscillate along their director axis due to the prevalent thermal fluctuations. In this work, we develop a theoretical model of the mechanics of microtubules in the cytosolic space based on the buckling of its structure due to these thermal fluctuations. This cytosolic space has been considered as a viscoelastic medium in which microtubule oscillations have been considered. As a result of resilience of cytosol and neighbouring filaments from the axial force due to thermal fluctuations, the surface traction acting laterally on the microtubule structure has been further used to elucidate its piezoelectric behaviour in vivo. After the piezoelectric properties induced by thermal fluctuations (in addition to the buckling) of microtubules have been discussed, we propose a model discussing how microtubules behave as energy harvesters and communicate via electromagnetic radiation, with each other, in an intracellular environment.


Biological cells are exposed to a variety of mechanical loads throughout their life cycles that eventually play an important role in a wide range of cellular processes. The understanding of cell mechanics under the application of external stimuli is important for capturing the nuances of physiological and pathological events. Such critical knowledge will play an increasingly vital role in modern medical therapies such as tissue engineering and regenerative medicine, as well as in the development of new remedial treatments. At present, it is well known that the biological molecules exhibit piezoelectric properties that are of great interest for medical applications ranging from sensing to surgery.

In the current study, a coupled electro-mechanical model of a biological cell has been developed to better understand the complex behaviour of biological cells subjected to piezoelectric and flexoelectric properties of their constituent organelles under the application of external forces. Importantly, a more accurate modelling paradigm has been presented to capture the nonlocal flexoelectric effect in addition to the linear piezoelectric effect based on the finite element method. Major cellular organelles considered in the developed computational model of the biological cell are the nucleus, mitochondria, microtubules, cell membrane and cytoplasm. The effects of variations in the applied forces on the intrinsic piezoelectric and flexoelectric contributions to the electro-elastic response have been systematically investigated along with accounting for the variation in the coupling coefficients. In addition, the effect of mechanical degradation of the cytoskeleton on the electro-elastic response has also been quantified. The present studies suggest that flexoelectricity could be a dominant electro-elastic coupling phenomenon, exhibiting electric fields that are four orders of magnitude higher than those generated by piezoelectric effects alone. Further, the output of the coupled electro-mechanical model is significantly dependent on the variation of flexoelectric coefficients. We have found that the mechanical degradation of the cytoskeleton results in the enhancement of both the piezo and flexoelectric responses associated with electro-mechanical coupling. In general, our study provides a framework for more accurate quantification of the mechanical/electrical transduction within the biological cells that can be critical for capturing the complex mechanisms at cellular length scales.

Birth: Study of Horses Shows Importance of the Big Squeeze

Nearly a third of childbirths in America happened by cesarean section in 2017, but whether a woman has a C-section may have more to do with where she gives birth than her health or that of her baby.

Health systems, policymakers and advocates are working to bring down C-section rates after a dramatic increase in the U.S. since the 1990s, and maternal health experts say curbing how frequently the procedure is performed for low-risk births – when a woman is giving birth at term, for the first time and to a single infant who’s in the head-first position – is key to these efforts.

[ALSO: What’s My Community’s C-Section Rate?]

Nationally, no more than 23.9% of births among low-risk women without a prior C-section should be through the procedure by 2020, according to the federal government. Among low-risk, first-time births overall, the C-section rate was 26% in 2017, according to data from the Centers for Disease Control and Prevention, and state rates ranged from 17.7% to 31%. Within states, the variation in these rates can be even greater at the hospital and provider levels.

Across the U.S., the overall C-section rate was 32% in 2017, down from 32.7% in 2013. These 10 states had the highest C-section rates in 2017, according to CDC data….
