Caltech biologists create the first predictive computational model of gene networks that control the development of sea-urchin embryos As an animal develops from an embryo, its cells take diverse paths, eventually forming different body parts–muscles, bones, heart. In order for each cell to know what to do during development, it follows a genetic blueprint, which consists of complex webs of interacting genes called gene regulatory networks. Biologists at the California Institute...

A quartet of studies by researchers at the California Institute of Technology (Caltech) highlight a special feature on gene regulatory networks recently published in the Proceedings of the National Academy of Sciences (PNAS).The collection of papers, "Gene Networks in Development and Evolution Special Feature, Sackler Colloquium," was coedited by Caltech's Eric H. Davidson, the Norman Chandler Professor of Cell Biology. His coeditor was Michael Levine, professor of genetics, genomics and...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
