Contained cell cluster beside scattered immune cells breaking tolerance

When the Immune System Attacks Itself: Autoimmunity and the Failure of Tolerance

When the Immune System Attacks Itself: Autoimmunity and the Failure of Tolerance Series: New Immunology | Part: 6 of 8 Primary Tag: FRONTIER SCIENCE Keywords: autoimmunity, tolerance, rheumatoid arthritis, multiple sclerosis, lupus, regulatory T cells How Tolerance Is Supposed to Work Remember that the adaptive immune system generates receptor diversity randomly.

Glowing planarian flatworm splitting into two regenerating bodies

Planarian Regeneration: The Champion Regenerators

Planarian Regeneration: The Champion Regenerators Series: Bioelectric Code | Part: 5 of 7 Primary Tag: FRONTIER SCIENCE Keywords: planaria, regeneration, stem cells, bioelectric memory, morphogenesis, Michael Levin The Planarian Puzzle Planaria are freshwater flatworms, typically a centimeter or two long. They're remarkably simple: no circulatory system, no respiratory system,

Two mirrored glowing flatworm forms, one showing a patterning signal

Morphogenetic Fields: How Bodies Know Their Shape

Morphogenetic Fields: How Bodies Know Their Shape Series: Bioelectric Code | Part: 4 of 7 Primary Tag: FRONTIER SCIENCE Keywords: morphogenetic fields, pattern formation, bioelectric gradients, positional information, developmental biology The Positional Information Problem Each cell in your body contains the same genome. Yet cells in your liver do liver things,

Neuron with voltage rings between blue and red branching dendrites

The Voltage of Life: Membrane Potential and Cell Fate

The Voltage of Life: Membrane Potential and Cell Fate Series: Bioelectric Code | Part: 2 of 7 Primary Tag: FRONTIER SCIENCE Keywords: membrane potential, Vmem, depolarization, hyperpolarization, cell fate, differentiation What Vmem Tells a Cell The membrane potential isn't just a passive consequence of ion gradients—it's

Cell drawn as a glowing battery with charged ions and channels

Your Cells Are Batteries: The Electrical Nature of Life

Your Cells Are Batteries: The Electrical Nature of Life Series: Bioelectric Code | Part: 1 of 7 Primary Tag: FRONTIER SCIENCE Keywords: bioelectricity, membrane potential, ion pumps, cellular electricity, Vmem The Basic Physics The electrical charge across a cell membrane arises from ion gradients—differences in the concentration of charged particles

Labeled bioelectric diagram with a regenerating limb, ion channels and DNA

The Bioelectric Future: A Synthesis

The Bioelectric Future: A Synthesis Series: Bioelectric Code | Part: 7 of 7 Primary Tag: FRONTIER SCIENCE Keywords: bioelectricity, regenerative medicine, developmental biology, Michael Levin, biological computation, coherence A New Layer of Biological Information The central insight is simple but profound: there's more information in biology than DNA. The

Orderly blue honeycomb cells breaking into chaotic red cancer cells

Cancer as Bioelectric Breakdown

Cancer as Bioelectric Breakdown Series: Bioelectric Code | Part: 6 of 7 Primary Tag: FRONTIER SCIENCE Keywords: cancer, bioelectricity, depolarization, tumor microenvironment, ion channels, oncology The Bioelectric Signature of Cancer Across tissue types and cancer types, a consistent pattern emerges: cancer cells are depolarized. Normal cells maintain a negative resting membrane
