Why do humans and mammals have a left-sided aortic arch, while birds have a right-sided arch and does arch side selection influence distribution of somitomeric blood and thus body part growth? Key question for Evoflow Lab - situations vacant matai.org.nz/cardioscience/
Alien Eukaryote: The Cell That Lost Its Mitochondria Life’s smallest rooms are predictable. Peer inside any eukaryotic cell and you’ll find the same architecture repeated: nucleus for information, endoplasmic reticulum for traffic, Golgi for packaging, and somewhere near the…
I love this work. I believe you can extend it with the concept of impedance. Physicists and electrical engineers care not only about resistance but the capacitance (ability to store energy) and inductance (inertia) of the flow of energy with electrons, and both of these — unlike…
Every breath we take delivers triplet oxygen into mitochondrial fields where electron flow drives charge separation, powering the quantum mechanical processes of life. Triplet oxygen (³O₂) is the ground state: calm, magnetic and unreactive. Two electrons spinning in parallel,…
The Gate That Counts Time (IMJ) Beneath the folds of a mitochondrion sits a bottleneck that appears anatomical yet behaves mathematical: the inner mitochondrial junction (tens of nanometres wide) as torsional filter, a region whose narrowness does not impede flow so much as…
The Mind Before the Brain Consciousness did not wait for neurons. Long before synapses, voltage maps, or spiking codes, matter was already computing with fields. Each membrane, each charge gradient, each spin-aligned molecule was a decision surface, testing geometries against…
Is “oxidative stress” a useful concept in biology? In this work, led by Nikos, we argue that the term “oxidative stress” is devoid of biological meaning and, even worse, misleading.

Reading this Lewis book now by coincidence. Profound:
“The greatest of [Shakespeare’s] sonnets are written from a region in which love abandons all claims and flowers into charity: after that it makes little odds what the root was like. They open a new world of love poetry; as new as Dante’s and Petrarch’s had been in their day.…

In the very first days of life, not all embryo cells are truly identical. Small differences in an enzyme called CARM1 guide the timing of cell changes that decide which cells make the embryo, and which make the placenta. elifesciences.org/articles/10896…
The C-value paradox: no simple correlation between the total amount of genomic DNA (C-value) and perceived biological complexity.

Such a beautiful artwork of echocardiography views — clear, colorful, well-organized, and very educational. A wonderful way to illustrate different echo views.

The human brain is not just electrochemical. It is also an electromagnetic organ with a built-in sensory system for magnetoreception. We’ve spent centuries mapping its chemistry, but overlooked a critical feature: the brain is in constant exchange with the physical environment…

... otherwise we could never have evolved from a bacteria-like ancestor in the first place. So: (1) bacteria are anticipatory (sensu Rosen) not reactive, (2) their behavior cannot be formalized (like a mechanism). I write about all this in detail here: link.springer.com/chapter/10.100…
... through communication) is the basic problem here. You are falling for the magic trick that is pattern repetition based on high-dimensional correlations in human-curated data sets, and call it "linguistic competence." There is no competence there. Just statistics.
Streaming in Single Ventricle Circulation Beyond mixing, streamingalso needs to be considered in understanding oxygen delivery.
