What's up in
Modeling suggests that many embryonic cells commit to a developmental fate when they become too small to divide unevenly anymore.
Paradoxically, the abundance of tight interactions among living species usually leads to disasters in ecological models. New analyses hint at how nature seemingly defies the math.
For the first time, researchers have traced the genetic programs that guide the development of each cell in early embryos. Surprisingly, even cells that start out different can end up the same.
The computational biologist John Novembre uses our genetic code to rewrite the history of humanity.
