The hottest Cryonics Substack posts right now

Despite preservation with the goal of future revival not being proposed for most of human history, in 1962, Evan Cooper and Robert Ettinger independently introduced the concept of cryonics.
Factors influencing the delay in proposing preservation with future revival include a need for optimism in technological progress, willingness to take risks, and advances in preservation technology.
Other possible reasons for the delayed start include societal restrictions, advancements in information theory, and the idea that preservation does not need to be perfect to be pursued.

Study on extrasynaptic neural signaling in C. elegans challenges the idea that synapses are the sole key to brain information content.
Neuropeptide signaling plays a crucial role in behaviors like aggression in mice, emphasizing its significance beyond nematodes.
Mouse amygdala study highlights differences in brain cell activity during memory formation and recall, shedding light on the complex processes of memory.

The brain's sensory information changes over time through representational drift
Memory formation and synaptic strength may have similarities in dendritic spine volumes
New methods are helping to identify and understand specific cell types in the brain

A big connectomics study of Drosophila larva was published, revealing new insights into neural connections
Simulated neural networks can accurately replicate properties of connectomes in different species
Research proposal aims to comprehensively measure input-output functions of all 302 neurons in C. elegans, a significant project in neuroscience

Robert Ettinger is considered the father of cryonics.
Ettinger's idea of cryonics was inspired by a science fiction story called The Jameson Satellite.
The concept of preserving bodies indefinitely for potential future revival is a key theme in cryonics.
