Evolution: One Penis After All

Current Biology : CB

Abstract

Amniote penises come in many shapes but are missing from the basal tuatara. This has been taken as evidence for multiple evolutionary origins of the penis. Now, genital swellings have been found in tuatara embryos, arguing for a single origin.

CREs: Gene & Cell Therapy

Gene and cell therapy advances have shown promising outcomes for several diseases. The role of cis-regulatory elements (CREs) is crucial in the design of gene therapy vectors. Here is the latest research on CREs in gene and cell therapy.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
