Long-form essays examining the scientific claims and limits of biological research, especially organoids in drug discovery, disease modeling, and Alzheimer's research. Readers get critical, detailed analysis of where lab models succeed, fail, and get overhyped, plus updates from the author's work on AI and health.

A retired cardiologist and former FDA official documents his personal effort to find a Parkinson's treatment, mixing commentary on recent trial results with his own research history and operational updates on drug development. Readers get a firsthand, detailed view of how a non-specialist approaches PD science and what regulatory and safety steps a potential drug must clear.

William Wallace, Ph.D. investigates the biochemistry behind health claims, checking each claim in an episode against the cited studies and marking whether the evidence is observational, animal-only, or untested in people. Recent issues cover nicotine and Parkinson's disease, whether microplastics accumulate in the brain, and the origins and evidence for the peptide BPC-157.

Dendrite is a personal newsletter by a neuroscientist covering academia, computational neuroscience, animal biology and books, with long, anecdotal essays that explain scientific ideas through vivid examples. Readers get reflective, well-explained science writing with a personal voice rather than news or links.
