The American Biology Teacher, 1969 Introduction The field of biology has been confronted recently with the paradox of being the only natural science which has yet to demonstrate that any of its terrestrially based conceptual schemes have any universal significance. The various thoughts, ideas, and principles of present day biology apply to only one kind of life-life on Earth.

Digital Detection of Oxide Breakdown and Life-Time Extension in Submicron CMOS Technology [PDF]
, 2008 An approach is introduced to extend the lifetime of high-voltage analog circuits in CMOS technologies based on redundancy, like that known for DRAMS. A large power transistor is segmented into N smaller ones in parallel. If a sub-transistor is broken, it

Oceanographic Considerations for Exoplanet Life Detection
Astrophysical Journal, 2019 Liquid water oceans are at the center of our search for life on exoplanets because water is a strict requirement for life as we know it. However, oceans are dynamic habitats—and some oceans may be better hosts for life than others.
