Equality of the sexes: Found in translation
Article Abstract:
The number of X chromosomes is half in male fruit flies than the female flies, still the expression of X-linked proteins in males is the same because of a sex-specific compensatory mechanism. A unique two-stage translation silencing mechanism that thwarts synthesis of a male -specific transcription activator in female flies, thus ensuring that gene dosage compensation occurs only in males is reported.

On regenerating the ovary and generating controversy
Article Abstract:
The claims that mouse germline stem cells (GSCs) replace ovarian follicles that are rapidly lost through follicle death are highlighted. Concerns regarding the putative role of bone marrow cells in reproduction and the experimental rigor needed to verify the revolutionary hypothesis is discussed.

Spiroplasma swim by a processive change in body helicity
Article Abstract:
Spiroplasma swimming is driven by the propagation of a pair of kinks along the cell body and these kinks are generated by a processive change in body helicity. A processive change in the helicity of the body creates the waves and enables directional movement.
