... respond and adapt to environmental changes, as well as changes during development, cell reprogramming and ageing. If you believe studying the dynamic nucleus is paramount to understand how the genome functions, support this initiative! 4DNucleome - initiative in Europe Nuclei of mitotic chromosomesCredit: David Sitbon, Ph.D. student in the Almouzni ...

Stefan Janusz reports on new ways of investigating embryo development. Stem cell therapy holds the key to regenerative medicine: replace defunct or diseased cells in an organ by injecting new cells derived from a continually replenishing source. This kind of therapy often relies on the [...] March 2010 Stefan Janusz reports on new ways of investigating ...

... which posited that all living organisms existed in miniature inside of the sperm (or the egg), and merely expanded in size over time [link]. In contrast, the theory of epigenesis proposed that embryos began as an undefined mass with new parts added during development (1). Conrad Waddington, described as a "renaissance biologist" (2), was a 20th century ...

... sought the quiet life offered by religious devotion. But her father had other ideas for her and encouraged the development of her skills as a linguist, mathematician and philosopher. Agnesi devoted herself to the study of mathematics and, having set out to write a textbook to help teach the subject to her younger siblings, she published a work that ...

... and believe in the importance of conveying the findings of our research to the public. 20 February, 2013 By Jane Mellor, and Edith Heard Research over the past century in genetics, developmental biology and more recently genomics, has led to the realization that DNA sequence cannot be the sole agent of heredity. Although heredity is firmly based ...

... affect development and behaviour. "The function of our DNA is not as fixed as previously thought," adds Michael Meaney (Douglas Institute, Quebec). "The interaction between genes and the environment plays a crucial role in determining our resistance to stress and the risk for suicide. Epigenetic marks are the product of this interaction." ...

... as a tool to better understand biological development. This work has fuelled many major breakthroughs in cancer research. A recent PLoS publication is no exception. Speculations from a group of Belgian biologists led them to uncover a genetic switch in flies that could be used to turn off cancer in humans. The scientists wondered whether genes that ...

... some of them are also involved in priming tissue-specific genes for expression at later stages of cell differentiation. The researchers found that ES cell factors Sox2 and Foxd3 bind to a tissue-specific enhancer within the λ5–VpreB1 locus. In ES cells the λ5 and VpreB1 genes are silent, but they are switched on during B cell development, where they ...

... has transformed the lives of millions of diabetics around the world. Without Dorothy Crowfoot Hodgkin’s (1910-1994) pioneering and patient efforts – over a period of some 35 years – to decipher this crucial hormone’s structure, its full potential may still not have been realised. All this was made possible by Crowfoot’s co-discovery and development ...
