When mammalian cells die, they do not simply dissolve away. Instead, they are actively deconstructed and destroyed in defined and organized ways by various regulated cell-death mechanisms. One of ...

Magdalena (Magda) Zernicka-Goetz, today a developmental and stem cell biologist at the University of Cambridge and California Institute of Technology, recalled being an artistic child who enjoyed ...

Animal embryos go through a series of characteristic developmental stages on their journey from a fertilized egg cell to a functional organism. This biological process is largely genetically ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

Animal embryos go through a series of characteristic developmental stages on their journey from a fertilized egg cell to a functional organism. This biological process is largely genetically ...

A small tissue fold in fly embryos, once thought purposeless, plays a vital role in stabilizing tissues. Researchers show that it absorbs stress during early development, and its position and timing ...

Microtubule asters in cytoplasmic extract of the African clawed frog Xenopus laevis. The spatio-temporal growth of the aster is coordinated by cell cycle waves that drive the polymerization (brighter ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our ...
