In parallel with modern man (Homo sapiens), there were other, extinct types of humans with whom we lived side by side, such as Neanderthals and the recently discovered Denisovans of Siberia. Yet only Homo sapiens survived. ...

(Phys.org) —In higher animals, an embryo's protein production immediately after fertilization relies on messenger RNAs (mRNAs) inherited from the mother. But shortly thereafter, the tiny organism undergoes a profound shift ...

Static models of gene regulation networks are inevitably oversimplified, indicating how one gene specifically switches certain target genes on while turning others off. However, the reality is much more dynamic and thus noisier. ...
