The disposable soma theory of aging was developed to explore how differences in lifespans and aging rates could be linked to life history trade-offs. Although generally applied for multicellular organisms, it is also useful for exploring life history strategies of single-celled organisms such as bacteria. Motivated by recent research of aging in E. coli, we explore the effects of aging on the f...

Aerosol particles in the atmosphere have recently been found to contain a large number of chemical elements and a high content of organic material. The latter property is explicable by an inverted micelle model. The aerosol sizes with significant atmospheric lifetimes are the same as those of single-celled organisms, and they are predicted by the interplay of aerodynamic drag, surface tension, ...

Since it is usually accepted that the more anaplastic bronchial carcinomas have a worse outlook, it might be thought that the type of cell found in a positive biopsy from bronchoscopy would give a clear lead as to prognosis. Indeed, Nicholson, Fox, and Bryce (1957) stated that the prognosis was best for squamous-celled growths and almost hopeless for spheroidal-celled, oatcelled, and anaplastic...
