The world is full of unusual unicellular organisms and microbes, many of which have not been discovered yet. In 2017, scientists identified a single-celled marine organism called Chromosphaera ...

Biologists have provided new insights on a longstanding puzzle in biology: How complex organisms arise from a single fertilized cell. Producing a new 'gene atlas' with 4-D imaging, the researchers ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

Mounting evidence from research on nematodes to mice indicate that a father's environment, such as what he eats or if he is ...

Until a few hundred years ago, before scientific advances allowed researchers to peer inside the human body or extract cells to study them in the laboratory, I imagine that the mysteries of ...

Infertility is a major healthcare concern. Understanding the molecular regulators governing fertilization, early embryonic ...
