For decades, scientists have been able to look at individual moments in the development of an embryo: a snapshot of a ...

The human body begins with a single fertilized egg formed by the union of a sperm and an egg. As the fertilized egg ...

Glycolysis is an ancient metabolic activity. It consists of a set of reactions that convert glucose into energy. This central process allows cells to grow, divide, and stay alive. It has accompanied ...

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 ...

C.H. Waddington’s powerful image of embryonic stem cells specializing on a rolling landscape has captivated biologists since the 1950s. Experimental data is finally confirming, and complicating, his ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive – particularly for egg-laying ...

Chimpanzee naive pluripotent stem cells (PSCs) can now be grown in cellular cultures, reveals a recent study. They successfully created chimpanzee early embryo models, called 'blastoids,' and found ...

Cultivated steak is notoriously difficult to produce. But a new study could make it easier, at least in theory. Researchers from the European Molecular Biology Laboratory (EMBL) Barcelona have ...

Humans have around 30 trillion cells in our adult bodies. Amazingly, each of these cells came from a handful of about 100 stem cells in the earliest days of development. The ability of these embryonic ...
