Low-temperature culturing improves survival rate of tissue-engineered cardiac cell sheets

open access: yesBiochemistry and Biophysics Reports, 2018
Assembling three-dimensional (3D) tissues from single cells necessitates the use of various advanced technological methods because higher-density tissues require numerous complex capillary structures to supply sufficient oxygen and nutrients. Accordingly,

Environment, Equivalence Inferences, and the Twins: A Reply to Sober

open access: yesPhilosophy, Theory, and Practice in Biology, 2021
Elliott Sober (2020) can be understood as advancing two distinct arguments that similarly conclude that evolutionary theory does not say that Scriven’s (1959) infamous twins have the same fitness, despite the twins’ identical genotypes and phenotypes ...

Shallow extra mixing in solar twins inferred from Be abundances [PDF]

open access: yes, 2015
Lithium and beryllium are destroyed at different temperatures in stellar interiors. As such, their relative abundances offer excellent probes of the nature and extent of mixing processes within and below the convection zone.
