Normal heart development requires appropriate levels of retinoic acid (RA) signaling. RA levels in embryos are dampened by Cyp26 enzymes, which metabolize RA into easily degraded derivatives. Loss of Cyp26 function in humans is associated with numerous developmental syndromes that include cardiovascular defects. Although previous studies have shown that Cyp26-deficient vertebrate models also ha...

Review of Jonathan Fox’s Religion, Civilization, and Civil War

In the past ten years there has been increasing interest in rigorous, quantitative analysis of the determinants of civil war, ethnic violence, and other forms of domestic conflict.

In the development of the vertebrate body plan, Wnt3a is thought to promote the formation of paraxial mesodermal progenitors (PMPs) of the trunk region while suppressing neural specification. Recent lineage-tracing experiments have demonstrated that these trunk neural progenitors and PMPs derive from a common multipotent progenitor called the neuromesodermal progenitor (NMP). NMPs are known to ...

Piracy and Innovation: Does Piracy Restore Competition?

One of the main issues usually associated with piracy is that it hinders innovation. As this leads to smaller profits, firms have no incentive to innovate. In this article, we show that even if piracy is usually seen as innovation “killer” it may, on the contrary, increase innovation: piracy places firms in a highly competitive environment and pushes them to innovate continuously in order to ma...
