Paternally contributed centrioles exhibit exceptional persistence in C. elegans embryos

C. elegans does it again. But how potentially non-genetic carriers like centrioles can carry biological information is still kind of a mystery. Doesn't make much sense to me.

Apoptosis and necrosis mediate skeletal muscle fiber loss in age-induced mitochondrial enzymatic abnormalities

mtDNA deletion mutations are causal in sarcopenia, and are concomitant with electron transport chain abnormalities, causing apoptotic mechanisms to activate, and cell necrosis.

Lefties, Language and Lateralization

Monogenic theory of handedness and lateralization results as having "hammered a nail in the coffin" because it was demonstrated that observed relationships between handedness and language lateralization did not involve genetic overlap. In other words, evidence goes to show that one single gene does not dictate handedness nor the part of the brain that one processes language with.
